Brief description of the 165 screw-cutting lathe

bed

The bed is the basic assembly unit on which all other assembly units and mechanisms of the machine are mounted.

On the top of the frame there are three prismatic guides, of which the front and rear are the base of the carriage, and the middle one is the base of the tailstock.

Inside the frame there are inclined hatches for removing chips and coolant in the direction opposite to the workplace.

Under the left head part of the frame there are niches, in one of which the main drive electric motor is mounted, and in the other - an electric cooling pump with a coolant reservoir. The trough for collecting coolant is made monolithic with the frame body.

On the right side of the frame, on the front wall, there is mounted a bracket with built-in supports for the lead screw and the drive shaft and a fast-moving gearbox for the caliper with a flange electric motor.

To prevent sagging of the lead screw and the lead shaft, the machine with RMC 5000 has two suspensions.

Front headstock of screw-cutting lathe model 165

Front headstock of screw-cutting lathe 165

The front headstock is installed on the left head part of the frame, fixed with pins and secured with bolts.

The following are mounted in the headstock housing:

• gearbox
• spindle unit
• eight-fold step increase link
• mechanism for changing the direction of movement of the carriage when cutting threads
• spindle speed adjustment mechanism
• Lubrication system
• electrical cabinet

The spindle is mounted on three rolling bearings, of which the front and rear are adjustable.

A description of the adjustment of spindle bearings is given in the “Adjustment” section.

Adjustment of the spindle rotation speed, as well as adjustment for cutting right or left threads of normal or increased pitch is done by moving the gears along the splined shafts using handles located on the front wall of the front headstock (see Fig. 37 and Table 22).

The shaft splines and gear teeth are hardened and ground.

Enabling the step increase link is possible only when working with brute force.

Tailstock

The rear headstock moves along the frame guides from the manual gearbox by rotating the roller 26 (see Fig. 3).

The headstock is attached to the frame using two clamps with three bolts.

For rigid fixation in the axial direction, there is a stop in the rear headstock, which can be inserted into the cast cavities of the frame using handle 27.

The headstock body moves along the bridge in the transverse direction (see subsection “Regulation”).

A rotating spindle is built into the headstock quill, the front support bearings of which are adjusted using nuts.

Rapid movement of the quill is carried out by the flywheel 29. Locking is carried out by the handle 33.

Slow movement of the quill is carried out by handles 31 through a worm gear, activated by handle 30.

For drilling, countersinking and reaming, by turning the pusher 28, it is necessary to turn on the gear coupling, which rigidly connects the spindle to the quill.

The tailstock spindle has a slot for the legs of the tail cutting tool.

When changing the center or tool, the quill must be pushed into the headstock body as far as it will go. In this case, the pusher pushes the center or tool out of the spindle.

Caliper and carriage

The cross-design support has longitudinal movement along with the carriage along the frame guides and transverse movement along the carriage guides. Both movements are carried out mechanically (with working feed and using a quick movement mechanism) and manually.

The cutting slide, carrying a four-position tool holder, is moved manually along the guides of the rotating part, which can be rotated around a vertical axis to any angle.

The nut of the screw pair for the transverse movement of the caliper is composite and separated by an adjusting wedge. The adjustment of the gaps in the guides of the carriage, the rotating part, made by wedges, in the screw pair of the transverse movement of the caliper is given in subsection 2.4. "Regulation".

Machine apron

The apron is a closed type with a removable front wall (lid).

The movement of the caliper group is transmitted by the apron mechanism from the drive shaft or lead screw.

Due to the presence of four electromagnetic clutches in the apron, control of the mechanical movement of the support group is concentrated in one handle 23 for controlling the mechanical strokes of the carriage and support (see Fig. 3), and the direction of activation of the handle coincides with the direction of feed.

By additionally pressing button 24 (see Fig. 3), built into handle 23, you can turn on the rapid movement of the caliper in the direction of tilting the control handle (23).

Thanks to the overrunning clutch built into the feed box, high speed can be activated when the feed is on.

The lead screw nut is split and is activated by handle 21 through a cam device.

To prevent simultaneous activation of the lead screw nut and the feed, there is an electromechanical lock.

A safety clutch mechanism is mounted in the apron, which prevents the machine from breaking due to overload. Its adjustment is given in subsection 2.4. "Regulation".

Gearbox

The feed box is a closed type with a removable front wall (lid).

The feed box mechanism allows you to get all the feeds and threads cut on the machine without having to change the settings of the replacement gears.

Set up the feed box for feeding or threading in accordance with table. 23 and 24 in the following order (see Fig. 3 and Fig. 38):

• move handle 10 to the “off” position
• move handle 14 to the “lead screw” position for cutting threads or to the “lead roller” position - to work with feed
• move handle 7 to one of three positions - “inch thread”, “modular thread”, “metric thread or feed”
• install handles 9, 12, 13 according to the table of feeds and threads on the required thread or feed, and to install handle 9 in the desired position, place the corresponding number on its disk under the pointer;
• move handle 10 to the “on” position

When setting up for cutting threads with a pitch of increased precision, connect the lead screw with gear couplings directly to the receiving shaft of the feed box in accordance with Table. 25 (see Fig. 39).

Replacement gears

A set of replaceable gears with icm = 2/3, which makes it possible to obtain on the machine all the threads and feeds specified in the “Passport” section, is installed on the wall of the front headstock.

The design of the interchangeable gear mechanism provides for the possibility of installing other sets of gears.

Ammo

The machine includes a four-jaw non-self-centering chuck with a diameter of 1000 mm.

Lunettes

For processing non-rigid parts, the machine is equipped with two steady rests - movable and fixed.

Screw-cutting lathe DIP-500 (1M65)

The DIP-500 screw-cutting lathe began to be produced instead of the 165th line lathe. With its help, it became possible to process large-sized workpieces in small-scale and individual production. Due to its high reliability and quality of manufacture, the machine was exported.

Today, these models are not produced, but you can choose their modern analogues.

Kinematic diagram of screw-cutting lathe 165

Bearing layout for screw-cutting lathe 165

The main movement is driven by an electric motor through a V-belt drive.

The gearbox provides the spindle with 24 different speeds of both forward and reverse rotation through kinematic chains according to table. 4.

The spindle is reversed by an electric motor.

Rotation is transmitted to shaft IX of the gearbox from the spindle through gears 21-22, 26-27 or from shaft V (when the step increase link is turned on eight times) through gears 16-24, 23-22, 26-27. Ball IX receives one or eight revolutions per spindle revolution, respectively.

The block of gears 25 and 28 is designed to change the direction of movement of the carriage when cutting threads.

The movement is transmitted to the feed box from shaft IX through replaceable gears 30-32-31.

The feed box communicates to the caliper through the overrunning clutch, the XXIII running shaft and the apron mechanism 32 longitudinal and transverse feeds.

The kinematic chain of longitudinal and transverse feeds is calculated using the formula

i = icm * ik.p * if

Where:

icm is the gear ratio of replaceable gears;

ik.p - gear ratio of the feed box;

if is the gear ratio of the apron.

The kinematic chains through which feeds are carried out are given in table. 5 for the feed box and in the table. 6 for the apron.

Threading is carried out through the kinematic chains of the feed box, given in table. 7. In addition, threading can be done by directly connecting the lead screw with replaceable gears, selecting the appropriate icm (see Table 24). The range of feeds and threads is expanded when using an eight-fold pitch increase link.

The list of elements of the kinematic scheme (see Fig. 4) is given in table. 8, and the corrected gears - in Table 9.

Design of sectional horizontal pump CNS 60-165

The main structural units of the pump are the casing and the rotor.

The housing includes suction and discharge line covers, guide vanes, front and rear brackets. The housings of the guide vanes, suction and discharge covers are tightened with coupling bolts.

The guide vane, ring (with sealing rings) and impeller form the pump section. The joints of the guide vane housings are sealed with rubber rings made of oil- and petrol-resistant rubber.

Due to the fact that the pump body consists of separate sections, it is possible, without changing the flow, to change the pressure by installing the required number of impellers and guide vanes with housings. In this case, only the length of the shaft and tie rods changes.

The pump rotor consists of a shaft on which impellers, a ring, a shaft jacket, a spacer sleeve, adjusting rings and a relief disk are installed. All parts on the shaft are tightened with a rotor nut.

The rotor is supported by two radial spherical bearings installed in the front and rear brackets in a sliding fit, allowing the rotor to move in the axial direction by the amount of the rotor “run-up”.

The bearing chambers are sealed with cuffs installed in the bearing caps.

The bracket is closed from the outside with a cover in which a rotor displacement control device is mounted.

Design Features

Any machine includes some standard components. They determine what functionality a particular type of equipment has.

bed

The bed acts as a load-bearing element. The remaining parts are attached to this part. Structurally, this part looks like two walls that connect to each other. Rigidity to a certain extent is given to it by the transverse elements that organize the connection. The machine is equipped with separate parts that move along the bed.

To solve this issue, special guides are provided.

• Three of the guides have a prism-shaped cross-section.
• One part is flat.

Headstock

The headstock is needed to simultaneously perform two functions:

1. The workpiece is fully supported while processing is in progress.
2. So that the part rotates in a certain way.

The front part of this equipment also contains handles responsible for controlling speeds. Thanks to this, the spindle can rotate at a certain frequency.

A special diagram is usually placed next to the handle. It is enough to study it once to understand when and what part is turned on.

The headstock in front houses a high-speed box, complemented by a rotating spindle assembly. Inside this part of the structure, special bearings can be used for rolling or sliding. The chuck of the device is fixed at the end of the spindle; a connection with threads is necessarily used in the process. This unit ensures that the part rotates in a certain way while processing is in progress.

To move the carriage on the machine, bed guides with a prismatic cross-section are used. This part must maintain certain properties such as accuracy and straightness. Neglecting such conditions will not allow you to get quality work in the end.

Operating principle of the sectional horizontal pump CNS 60-165

The operation of the pump is based on the interaction of the rotating impeller blades and the pumped liquid.

Rotating, the impeller imparts a circular motion to the fluid located between the blades. Due to the resulting centrifugal force, the liquid from the center of the wheel moves to the external outlet, and the vacated space is again filled with liquid coming from the suction pipe under the influence of the created vacuum.

Having left the impeller of the first section, the liquid enters the channels of the guide vane and then into the second impeller with the pressure created in the first section, from where it enters the third impeller with increased pressure created in the second section, etc.

The liquid released from the last impeller flows through the guide vane into the discharge cover and from it into the discharge pipeline.

During pump operation, due to water pressure on the unequal area lateral surfaces of the impellers, an axial force arises, which tends to displace the pump rotor towards the suction side.

To balance the axial force, the pump is equipped with an unloading device, consisting of an unloading disk, an unloading ring and bushing, and a spacer bushing.

The liquid from the last stage passes through the annular gap between the unloading bushing and the spacer bushing and presses on the unloading disk with a force equal to the sum of the forces acting on the impellers, but directed towards the discharge. The pump rotor is balanced, and equal forces are established automatically.

The liquid leaving the unloading chamber cools the oil seal on the pressure side.

The suction side seal is flushed with liquid supplied under pressure from the suction line. The liquid, passing through the shaft jacket through the stuffing box, prevents air from being sucked into the pump and at the same time cools the stuffing box. Most of the liquid passes through the gap between the shaft jacket and the hydraulic seal sleeve into the suction cavity, some passes between the shaft jacket and the oil seal on the suction side, cooling it, the rest comes out through the fitting.

The tightening of the stuffing box should allow the pumped liquid to leak out between the shaft and the stuffing box packing in an amount of 5-15 l/h. A smaller number indicates that the oil seal is over-tightened, which increases friction losses and accelerates wear of the shaft jacket and rotor nut.

The pump rotor is driven by an electric motor connected to the pump through an elastic sleeve-finger coupling, consisting of two coupling halves (pump and electric motor) and fingers with rubber bushings.

The direction of rotation of the pump rotor is clockwise when viewed from the electric motor.

The pump and electric motor are installed on a common foundation plate so that there is a gap of 10 mm between the coupling halves when the pump rotor is shifted completely towards the suction side.

The unit's electric motor must be grounded before operation.

The CNS pump has self-priming capabilities. This condition is achieved by installing a valve inside the pump.

As part of the central nervous system pumping unit, as a rule, general industrial asynchronous electric motors are installed on the pump. Most often, a three-phase asynchronous motor with a squirrel-cage rotor is used for these purposes.

Pumps are manufactured with both stuffing box and mechanical seals. Leaks through mechanical seals - according to the technical documentation for mechanical seals.

The pump support brackets are made of cast iron, the material of the flow part of the pumps is TsNS SCh-20, Steel 35L, the shaft is steel 40x, the guide vane, ring and body of the guide vane, the oil seal bushing is made of press material AG-4V. The pump shaft is sealed using an stuffing box packing with a cross-section of 10 mm.

CNS pumps operate stably and for a long time with a headwater of 2-6 m. In the absence of headwater at the inlet, cavitation quickly destroys these high-speed pumps. When installing them to pump water with a temperature of more than 45°C, it is necessary to increase the pressure at the inlet to the pump.
