Description

The invention relates to machine tool design and can be used to handle detonated type of gear wheels.

Known machines are for rolling triangular and involute splines, which contain grippers mounted on spindles of fixed and movable heads 1.

However, these machines have a low accuracy of part positioning and are not adapted for automatic loading.

A machine is known for machining parts, containing a grandmother with a mandrel, a tool head, a magazine, and a feeder with a prism that can be rotated from the stop 21

A disadvantage of the known automaton is the unreliability of its operation.

The aim of the invention is to increase the reliability of the machine.

This goal is achieved by the fact that the support is fixed on the store and is made in the form of a single-acting latch.

FIG. 1 shows a machine for processing parts, a common type; in fig. 2 - kinematic diagram of the automaton; in fig. 3 - the moment of loading

details; in fig. 4 - moment-unloading details; FIG. 5 is a section A-L in FIG. 3 in FIG. 6 is a sectional view BB in FIG. four.

The machine for machining parts consists of the base 1, the headstock 2 with the mandrel 3 and the piston drive 4, the tool of the mental head 5 with the thumb pin and the hydraulic cylinder 7, the magazine 8 pi10 tatel 9 with the prism 10 on the axis 11, the finger 12 on the prism 10f of the latch 13 in as a two-armed 1 bar with a counterweight 14 and an emphasis 15 fixed on the store 8, as well as a diverter

15 tray 16..

The machine works as follows.

The magazine 8, when moving to the left, down, to the right, supplies the part to the prism 10, and the latch 13 becomes under.

20 finger 12 prism 10 fig..Z), Feeder 9 lowers the prism 10 with Detail to the treatment area. Teeth parts are meshed with knurling teeth. At the same time, the latch 13 / turning around the axis of the axis allows the prism of 12 prisms; 10 free to go down, and then under the action of the counterweight is in its original position. The piston actuator 4 feeds the mandrel 3 to the base hole of the part and simultaneously to the second.

support of the headstock 2, Instrumental head 5 under the action of a hydraulic cylinder

7 moves to the distance required for running in, running in occurs. After processing, the mandrel 3 releases the part and the feeder 9 raises it up. At the same time, the prism 10, resting its finger 12 on the latch 13 of the magazine 8, rotates around the axis 11 (Fig. 4), dropping the part

8 diverting tray 16. By turning, l latch 13 holds the stop 15. The next store 8 moves upwards and the prism under its own weight takes its initial, horizontal position. Then the cycle is repeated.

The proposed design of the automaton improves the accuracy of machining the gear ring of the wheel relative to the base hole and the reliability of the automated loading and drawing of the part.
