Abstract

Use: mechanical engineering, machining of parts such as rolling elements. Summary of the Invention: On the base 1, the table 2 moves longitudinally. On the carriage there is a milling headstock 3 carrying the milling cutters 4. To the left and right of the power table, racks 6 are installed for parts. The milling cutters 4 are located on the spindle parallel to the axis of the cartridges 6. When the carriage moves perpendicular to the axis of the cartridges, the part is milled by the mills 4. The tool holders 8 with the cutters 9 located at the other end of the carriage opposite the mills 4, finish turning the part. The longitudinal turning of the parts was carried out by yut cutters, the tool holders of which are mounted on retractable rolling pins mounted on racks. 4 il. with s

Description

The invention relates to a machine tool industry and can be used for machining parts such as rolling bodies.

A known machine for milling crankshafts, comprising a power table moving longitudinally mounted on a frame with a milling headstock carrying two milling cutters and supporting posts with cartridges for fastening.

This machine has no tools for surface finishing and does not provide for longitudinal turning of surfaces, which reduces its technological capabilities.

Also known is a machine for processing cylindrical surfaces, including a table mounted on a bed, racks

with work cartridges, the headstock carrying the spindle for cutters, the axis of which is parallel to the axis of the cartridges.

This machine also lacks tools for surface finishing and does not provide for longitudinal turning of surfaces, which reduces the technological capabilities of the machine.

The aim of the invention is to expand the technological capabilities of the machine through the implementation of finishing operations and turning operations.

For this, the machine, which includes a table mounted on the bed, racks with cartridges for the workpiece, the headstock carrying the spindle for the cutters, the axis of which is parallel to the axis of the cartridges, is provided with a carriage placed

on the table with the possibility of moving perpendicular to the axis of the cartridges, rolling pins mounted on racks for moving along the axes of the cartridges, and holders for cutters, some of which are fixed on rolling pins, and others on the carriage, while the headstock is mounted on one side of the carriage , and holders for incisors - on the other.

FIG. 1 shows the proposed machine, plan view; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a view B in FIG. one; in fig. 4 - view B in FIG. one.

The machine contains a frame 1, on which a power table 2 moving in the longitudinal direction is mounted. On the carriage of the power table 2 there is a milling headstock 3, carrying two mills 4. To the left and right of the power table 2 on the frame 1 there are fixed supports 5 with cartridges 6 for fastening details.

The milling cutters 4 are mounted on a spindle 7, which is generally parallel to the axis of the chucks. In addition, at the other end of the power table 2 carriage, tool holders 8 with cutters 9 are located opposite the milling cutters 4 for finishing the surfaces of the parts 15.

For longitudinal machining of the parts 15, retractable rolling pins 10 are mounted on the support posts 5, on which the tool holders 11c are located with cutters 12.

For transferring the workpieces 15 from the boring machine 13 to the milling machine there is a portal two-handed manipulator 14.

The machine works as follows.

The part 15 machined on the boring machine 13 is fed by the manipulator 14 to the loading zone. The workpiece 15 is then lowered to the axles of the support posts 5 and secured by the cartridges 6. The workpiece 15 is attached to the rotation.

The carriage of the power table 2 mounted on the bed 1 begins to move with the working feed and the part 15 is milled by mills 4 rotating

on the common spindle 7. After machining the part 15, the milling head 3 is retracted to its original position. Then the carriage of the power table 2 receives the working feed in the opposite direction and is finished machining the part 6 with the cutters 9 on the tool holder 8 opposite the milling cutters 4. When the machining of the power table 2 is finished, the carriage 2 again returns to its original position, longitudinal turning begins.

5, the parts 15 are cutters 12 in the tool holders 11 by sliding them over the rolling pins 10 and withdrawing them to their original position.

The finished part 15, at the end of the treatment, is picked up by one of the hands of the portal handle 14 and is transferred to
