Abstract

The invention relates to a mechanical assembly production, in particular to devices for pressing the cuffs and bearings into the housing. The aim of the invention is to expand the technological capabilities of the device. To do this, it contains a drive working head (WG) 2, in the axial cavity of which a pusher 5 is axially spring-loaded. The cradle 13 is fixed to the housing for mounting the housing and the spring-loaded mandrel 14 for locating the cuff and bearing relative to the housing. On the inner surface of the WG, radial protrusions are mounted, which are included in the transverse shaped groove located along the perimeter on the outer side surface of the pusher. The side walls of the groove are made with triangular protrusions, providing a different position of the end of the pusher 5 relative to the working head. On the pusher is fixed a lever 7, in contact with the stop 12, mounted in the upper part of the frame. When pressure is applied to the rodless cavity of the pneumatic cylinder, the RG moves down, the pusher spring expands, after which the plunger, which interacts with the side walls of the shaped groove with the radial projections of the RG, turns and fixes in the desired position relative to the end of the RG. Thus, press fitting into the body of the cuffs and bearings of various sizes is provided. 6 Il. (L 15 CO 4 SP 05 Fig. 1

The device contains an operating head 2 mounted on frame 1, mounted on the rod of pneumatic cylinder 3, having an axial cavity 4 in which a pusher 5 is placed, installed with the possibility of axial reversing and spring-loaded by means of a spring 6. On the shank of the pusher there is a lever 7, and on the inner surface The working head is mounted radial protrusions 8, included in the transverse figure groove 9, located around the perimeter on the outer side surface of the pusher. The side of the off-cylinder 3 is located on the side wall 10 of the shaped groove 9 made in the form of triangular projections arranged with the same pitch and having the same height, one side (A) of each of which is at an angle smaller than the angle of the other side B. Opposite side the wall 11 is made in a wagging alternating with depressions of different depths of triangular protrusions, one side (B) of each of which is angled to the axis of the working head, smaller than the second (D), and the pitch is equal to the pitch of the protrusions opposite to second groove wall. The sides of the protrusions (B and D) of the side walls located at a large angle have the opposite direction, and the top of each protrusion is located opposite to the side of the opposite protrusion having a greater inclination. The difference in the depths of the depressions h ensures the movement of the pusher 5 beyond the limits of the working head 2 on
