Technical characteristics of the radial drilling machine 2K52

All equipment of this type is designed to work with large workpieces, whose free movement on the table is impossible or takes a lot of time.
If we delve even deeper into the information about the operation of the machine, it is easy to find out that it is used to produce a large or small number of parts, especially those of the same size range. This feature makes it easy to complete standard orders in a short time.

It is easy to perform the following types of work on the equipment:

• drilling;
• countersinking process;
• reaming;
• deployment;
• thread cutting.

There is a variation of this machine, it is called a radial drilling machine 2K52-1. The difference between these two units is the landing and secondary connecting bases. The location of these parts allows you to expand the range of use of the machine in the production of small-sized parts.

Kinematic diagram of the radial drilling machine 2K52

Base of radial drilling machine 2K52,2K52-1

The base is a rigid casting on which the plinth in which the column is installed is mounted. On the column there is a barrel with a sleeve and a drilling head.

On the base there are attached supports that serve to increase stability and align the surface of the slab in a horizontal plane.

Barrel of radial drilling machine 2K52,2K52-1

The barrel is a housing for the following assembly units: gearbox, switching mechanism, clamping mechanism, lifting mechanism and electrical equipment.

How does the machine work?

Here are the main details of the machine:

• base;
• Column;
• frame;
• barrel sleeve;
• drilling head;
• electrical equipment;
• carriage.

Machine carriage

The body and sleeve are attached to the base, and a container for cooling liquid is attached to the end part.

The column is a large steel pipe, which is installed in the base and attached with two bearings. Electrical equipment and clamping mechanisms are also located there; it is worth knowing that clamps are not included with the original equipment, they must be ordered separately.

A densely shaped cast iron is the housing, which is the main part for the gearbox. It also has space for electrical equipment.

The sleeve is attached to the body part by means of four clamps. In the direction of this part, a carriage moves along with a drilling head.

The head itself consists of a spindle, a control device and a feed box.

The spindle is made of cast iron. Has a large range for drilling frequency.

Design of radial drilling machines

Each radial drilling group machine consists of:

• hard base,
• cylindrical columns (internal and external),
• traverses (trunk),
• drill head (spindle head),
• electrical and hydraulic control equipment.

Kinematics

The main movements during drilling operations are the rotation and movement of the machine spindle quill. The kinematic chains that perform these movements are equipped with controls that allow the tool to be set to the required rotation speed and feed.

• rotation of the movable column of a radial drilling machine,
• vertical movement of the console (traverse),
• fixing the traverse on the column at operating height,
• fixing the spindle head on the traverse,
• switching spindle speeds and quill feeds.

When processing parts on radial drilling machines, the coordinates of the center of the hole and the axis of the tool are combined by moving the drilling head relative to the stationary workpiece in the polar coordinate system. This system is characterized by two parameters: the angle of rotation of the traverse and the radius of the position of the spindle head on it.

Machining holes at an angle is only possible when the workpiece itself is installed at an angle using special equipment and devices.

Stand with work table

The machine bed, combined with the working base (table), is usually cast from gray cast iron. It is designed to fix the entire machine on the foundation, install the column base with the traverse and the spindle head, as well as fasten the equipment and parts using the T-shaped grooves of the working base.

A workpiece of small dimensions can be installed on an attached box-shaped table, or directly fixed on a specially treated surface of the base (work table). Fastening the workpiece outside the working surface of the table is rarely used, because introduces an additional error into the processing accuracy of the product.

Rotary column

The column is mounted vertically on the machine bed and rotates around its axis relative to a fixed internal stand on roller bearings. The traverse is fixed to the column.

A mechanism for raising/lowering the traverse, driven by an electric motor, is mounted in the upper part of the column.

Traverse (console)

The console (arm or trunk) of the radial drilling machine is mounted directly on the column; it has a separate electric drive, moves up and down, and also rotates around a vertical axis together with the support column. Rotation, depending on the machine model, can occur either manually or using an electric drive.

A drill head with a working spindle is installed on the guides of the cantilever traverse. The traverse can be lowered or raised according to the height of the workpiece. Electrical equipment and hydraulic elements are mounted in a niche located on the reverse side of the sleeve.

Spindle head

The drill head (spindle head), mounted on a traverse, is structurally a separate power unit, having feed boxes, speed boxes, as well as mechanisms for setting the drilling depth.

In radial drilling machines, the spindle serves to fix the processing tool and transmit torque and linear feed to it.

The tool is inserted into the inner cone of the quill (Morse taper No. 4-6 or metric taper, depending on the model), and then coordinately oriented relative to the workpiece by rotating the console and moving the spindle head along it.

For operator convenience, all machine controls are located on the drilling head:

• multifunctional steering wheel for moving the spindle headstock and spindle quill;
• buttons for controlling the clamping/unclamping of units, turning on/off spindle rotation, emergency stop, turning on the work area lighting;
• handles for selecting rotation speed, spindle feed, direction of spindle rotation, switching between manual and automatic feed.

The feed box is located between the spindle and the spindle motor; Rotation from the electric motor is transmitted through gears and friction couplings. The friction clutch allows you to quickly reverse when cutting threads, cut off the feed when the required drilling depth is reached, and protect the gearbox from overloads.
