Abstract

This invention relates to mechanical assembly production, in particular, to devices for dismounting press joints. The invention allows to increase the productivity and simplify the construction of the device for dismantling the pressing tools connected by performing a pressing mechanism in the form of coaxially mounted stops: one adjustable, tl on the drive frame (P) 4, and the other 13 on the frame 1. The gripping unit is made in power cylinders 5, which move the clamping jaws 8 and are mounted on P. The assembly to be dismantled is mounted on the support 2, the power cylinders are included, which, with inclined pressure elements 6, fastened to the rods, move the jaws 8 to the front slots.

Description

(D) 9. knot. The drive P is turned on, and D 9 and 14 are pressed out. With further movement of P, the stop 11 presses the shaft 12 out of the undershield D 10, and the stop 13 - the shaft 12 from the bearing

This invention relates to mechanical assembly production, in particular, to devices for dismantling press joints.

The objectives of the invention are to increase productivity by ensuring the dismantling of the three press joints in a single drive stroke.

The press-in mechanism of the device is made in the form of two mounted stops, one of which is mounted on the frame, and the other on the drive frame, and the gripper assembly is made in the form of power cylinders mounted on the frame, which drive the clamping jaws, which are installed perpendicular to the pressing axis.

In the drawing of the image; 1o device for disassembling the press joints, general view.

The device for disassembling the press joints comprises a frame 1, a support stand 2, guide columns 3, a movable frame 4 connected to a power drive, for example, a hydraulic cylinder, on which two power cylinders 5 are vertically fixed, a rod wedge 6, which transmits force through rollers 7 on the clamping jaws 8, which serve to remove part 9 from the upper pressed out part 10 "On the frame 4 there is an adjustable stop 11 for pressing out the shaft 12 from the bearing of the top pressed out part 10, On the bed 1 there is a fixed stop 13, serving for pressing out the shaft 12 from the bearing of the lower repressible part 14,

The device works after; in this way.

The product is installed on the support stand 2. Under the action of the power CYLINDER 5, the clamping jaws 8 through the rod wedge 6 and the rollers 7 clasp the part 9, the force is sent 14. The removed D are removed, the drives return the mechanisms to their original position, the new node is installed on the support, and the cycle is repeated, 1 sludge.

The drive, under the action of which the frame 4 begins to move downwards and removes the part together with the lower part 14 that is being repressed.

During the further course of the frame 4, under the action of the stop 11, the shaft 12 is pressed out of the bearing of the upper part 10, and under the action of the stop 13, the shaft 12 is pressed out of the upper part 10

lower part 14.

In the lower position of the frame 4, the command is issued. dilution of the clamping jaws 8 and the return of the frame 4 to the original

position. .
