on the spindle head there is a speed switching mechanism, a mechanism for selecting the feed rate, a button for turning on the steering wheel, a handle for turning on the faceplate and a handle, the activation of which makes it possible to move the faceplate support from the steering wheel when cutting threads with a table;
on the lower sled tables there is a finishing operator on a flexible hose for fine installation of moving units;
Optical reading devices have buttons for turning on the optics lighting.

Descriptions of the digital display control panel and the numerical program control device panel are given in the second part of the operating manual.

Controls on the main console

Work body voter

Description of the main components of horizontal boring machines 2A622

bed

The frame with four guides has a closed box-shaped section with walls reinforced by a system of longitudinal and transverse stiffeners. Three rows of shoes allow you to quickly and easily align the bed guides with the required accuracy.

When making machines with an increased transverse table travel, two additional side guides mounted on shoes are located on both sides of the main bed (Fig. 13).

The bed has wide flat ground guides with telescopic protection, ensuring long-term preservation of the original accuracy.

At the end of the frame there is a gearbox with an electric motor that drives the movement of the spindle headstock, spindle, radial support and table longitudinally.

The distribution of movements is carried out by means of electromagnetic couplings.

Front pillar

The front post, which carries the spindle head, is rigidly fixed to the plane of the frame and has high rigidity and vibration resistance.

Front guide posts - flat, polished; The side guides are hardened overhead steel strips along which the spindle head moves on rolling rollers.

Headstock

The spindle headstock is a unit consisting of interconnected mechanisms mounted inside and outside the headstock body: the drive of the main movement mechanism, the spindle device, the mechanisms for moving the spindle headstock, the boring spindle, the radial support of the faceplate (for machines 2A620-1, 2A620F1-1 and 2А620Ф2-1), tail section, control mechanisms and counting of movements of the boring spindle and radial support of the faceplate.

The drive of the main movement mechanism of the spindle head is carried out from a flanged single-speed three-phase electric motor using a spring coupling of variable stiffness through an intermediate gearbox with two electromagnetic couplings located on the side wall of the spindle head body.

The spindle device consists of a boring and hollow milling spindle.

boring spindle moves inside heat-treated bushings pressed into the milling spindle.

The milling spindle is mounted in precision cylindrical and tapered roller bearings.

The front end of the milling spindle is equipped with a flange having a cylindrical seating surface, an end keyway and threaded holes for securing tools and fixtures.

The faceplate with radial support is mounted on its own spindle.

The moving mechanisms of the spindle head, spindle and radial support are kinematically connected to a DC electric motor through a gearbox located at the right end of the frame and a vertical shaft.

All moving parts are supplied by DC electric motors with a wide range of drives.

The feed rate variator for the moving parts is located on the spindle head next to the speed switching mechanism and is a two-row multi-stage switch with a feed rate scale in millimeters per revolution. The amount of feed of the movable element can be changed during the cutting process. When changing the spindle speed, the feed rate in millimeters per revolution is automatically maintained constant when the feed rate in millimeters per minute actually changes.

Table

The rotary table of the machine has longitudinal and transverse movement and is centered in a support with a precision cylinder-roller bearing.

When making machines with an increased transverse table travel of 1600 mm, detachable side supports are installed on the lower table slides, moving along two additional side guides,

The side guides of the lower table slide are hardened steel bars along which the upper table slide moves on rollers.

The longitudinal movement of the table is carried out by a DC electric motor through a gearbox located at the right end of the frame. Transverse movement and rotation of the table—from a DC electric motor through a gearbox located at the rear end of the lower slide. The distribution of movement is carried out by electromagnetic couplings.

Drive of the main movement of horizontal boring machines 2A622

The spindle and faceplate rotation is driven by a two-stage speed unit with electromagnetic clutches mounted on the spindle head. Kinematic diagrams of the machines are shown in Fig. 14, 15 and in table. 2.

To protect against dynamic impact, the main drive mechanism has an elastic coupling (Fig. 16).

The transmission of motion to the spindle is carried out by two pairs of gears 63, 64 (100) and 65, 66 (69) (Fig. 17, 18, 19). The larger wheel 64 (100) rotates the spindle in the lower speed range with high torques, and the other, smaller wheel 66 (99) rotates the spindle in the upper speed range with lower torques. The movement is transmitted to the faceplate by a pair of wheels 36, 35. To turn on the rotation of the faceplate, there is a special handle.

Drive for spindle feed, radial support, faceplate, spindle headstock and longitudinal movement of the table

The axial movement of the spindle, the radial movement of the faceplate support (Fig. 20), the vertical movement of the spindle head and the longitudinal movement of the table are carried out from a common DC electric motor through a gearbox, which is located on the machine bed (Fig. 21).

The distribution of movement in the movement chain of the spindle, spindle head, radial support and table is carried out longitudinally by means of electromagnetic couplings.

The kinematic chain of the radial caliper drive has a planetary mechanism with satellites 26 and 71, which allows the caliper to move during rotation of the faceplate (Fig. 22).

Axial movement of the boring spindle is carried out by ball screws 86 and 84, located in the tail part of the spindle head (Fig. 23).

Vertical movement of the spindle head is carried out by means of a rotating nut located in the gearbox on the spindle head and a stationary ball screw mounted on the stand (Fig. 24).

The machines are equipped with a mechanism to prevent the spindle head from falling when the counterweight cable breaks (Fig. 25).

When the spindle head counterweight is suspended, part 243, connected to the counterweight cable, is in the upper position, compressing the package of disc springs 244. In this case, ball 245, resting against the shoulder of part 243, through a system of levers fixes part 248 mounted in the spindle head gearbox in the upper position.

If the counterweight cable breaks, part 243, under the influence of a package of disc springs 244, will move down, releasing ball 245 and part 248 through the lever system. Part 248, under the influence of spring 249, will move to the lower position and engage with part 247, which secures shaft 246 from rotation. At the same time, the spindle head is securely fixed from falling.

Drive for lateral movement and rotation of the table

Transverse movement of the table and rotation of the table are carried out from a common DC electric motor through a gearbox, which is located at the rear end of the lower sled.

The distribution of movement to the chain of transverse movement and rotation of the table is carried out by means of electromagnetic couplings in the gearbox (Fig. 26).

Kinematics of thread cutting

The machine allows you to cut metric and inch threads (see “Table of replacement gears for thread cutting”).

Thread cutting is carried out by a retractable spindle during its axial movement or by a radial support of the faceplate during longitudinal movement of the table.

For thread cutting, the spindle feed chain is connected to the spindle rotation drive via a guitar with a set of replaceable gears located at the front end of the spindle head.

To cut left-hand threads on the guitar, an idler gear is installed.

To move the faceplate support away from the steering wheel when cutting threads using the table feed, turn on the handle located on the spindle head cover.

Kinematics of the helm

The spindle head has a steering device for manual movement of the spindle, radial support, spindle head and longitudinal movement of the table.

The turret allows for fine movement of the moving body and rapid movement of the retractable spindle.

The steering wheel is turned on using a button from the remote control on the spindle head.
