Abstract

The machine for hardening parts contains a bed, an inductor, a sprayer, as well as a centering device consisting of a lower plate 8, an upper plate 9, an emphasis 14, cams 13 and copiers 10. Installation part 18. is placed on the upper plate 9, which, under the action of gravity of the part, moves downward along the guide bushings 11. In this case, the swinging cams 13 interact with the copiers 10 and adjustable stops 14 to center the part. The shape of the centering device allows precise alignment of the workpieces, which improves the quality of their processing. 3 ill.

Description

The invention relates to the heat treatment of parts.

The aim of the invention is to improve the quality of quenching by improving the alignment accuracy. ,

The goal is achieved in that the centering device is made in the form of a coaxially mounted lower plate with guides in the form of bushings and a copier and an upper guide with a central hole, with stops mounted on it and spring-loaded columns mounted on the lower surface interacting with the bushings and cams.

In FIG. 1 shows the proposed machine; 2 — view A in FIG. 1; in Fig.Z - section bB in Fig.2.

The product hardening machine comprises a bed 1, an inductor 2, a sprayer 3, a mechanism for loading 4 and unloading 5 products, as well as a centering device 6 with a rotation drive 7.

The centering device 6 consists of a coaxially mounted lower 8 and upper 9 plates. A copier 10 is made on the lower plate 8, as well as a guide sleeve 11. The upper plate 9 is made with a central hole. The swing cams 13 with adjustable stops 14 are mounted on the plate 9 on the axes 12. The center of gravity of the cams 13 is offset relative to the axis of swing 12.

On the lower surface of the upper plate 9, columns 15 are mounted, spring-loaded with springs 16.

To limit the movement of the upper plate 9 under the action of the springs 16, restriction washers 17 are used.

The machine operates as follows.

The part 18 is fed into the loading zone of the machine using the loading mechanism 4 and is mounted on the upper plate 9 by the robot. Under the influence of the gravity of the part 18, the plate 9 moves down. Wherein

the columns 15 also move down the guide sleeves 11.

The swinging cams 13 interact with the copier 10. In this case, the swinging cams 13 are rotated upwards about the axis and, with adjustable stops 14, center the part 18.

After quenching is performed, the part 18 rises with the gripper of the robot. In this case, the plate 9 under the action of the springs 16 also rises. The swinging cams 13 come out of interaction with the copiers 10 and, due to the displaced center of gravity, rotate to the initial position, and the adjustable stops 14 release the part.

The use of the inventive machine will reduce the marriage during hardening of parts by increasing the centering accuracy, simplify the design of the device and ensure its more reliable operation, expand the range of hardened parts, since the presence of holes in the plate makes it possible to harden along the entire length of the workpiece.
