Processing method for integrally riveting separated type retainer

Abstract

The invention relates to a processing method for integrally riveting a separated type retainer. The processing method is characterized in that a punching head (5) is arranged in a clamping jaw (3); the diameter of the punching head is matched with that of a rivet hole of a retainer (2); the punching head is fixed through a locknut (4); the distance between the head part of the punching head and the end face of the locknut is H2; a supporting head (7) is arranged at one end of a round supporting platform (1); the diameter of the supporting head is matched with that of the punching head; the height of the head part of the supporting head extending out of the plane of the supporting platform is H2, wherein 2H2 plus H1 equals to H; a rivet (6) is inserted into the rivet hole of the retainer and sleeved on the supporting head; the clamping jaw is inserted in the upper part of the rivet hole of the retainer; a pressure frame is arranged at the end of the supporting platform, which is near the supporting head; the stroke of the pressure frame is set; the pressure frame aligns with the upper part of the clamping jaw; in the downward motion process, a cone of the head part of the punching head and a cone of the head part of the supporting head rivet the rivet at the same time; after riveting is finished, the pressure frame returns to the original position; and the rivet in the rivet holes of all the retainer can be riveted in the same manner.

Description

technical field [0001] The invention belongs to the technical field of bearing cage processing, in particular to a processing method for integral riveting of a detachable cage. Background technique [0002] The separated cage is composed of two symmetrical metal cages. For the two halves of the blank metal cage, several rivet holes must be processed first, and then the two halves of the metal cage are riveted into a whole cage by several rivets, and finally Subsequent finishing is carried out according to the requirements of the finished product, such as the inner and outer diameters of the fine car cage. [0003] The current riveting method adopts a manual method, the rivet is penetrated into the rivet hole, the two sides of the rivet are riveted and the burr is removed by the taper pin, and then the next rivet is riveted, and so on. [0004] The disadvantages of manual riveting are as follows: [0005] 1) When riveting, the rivet hole must be found first, and there is no...

AI Technical Summary

Problems solved by technology

[0005] 1) When riveting, the rivet hole must be found first, and there is no positioning reference;

[0006] 2) The strength of hitting the cone pin with a hammer during riveting is inaccurate, either the riveting is too heavy or the riveting is too light, the yield of riveting cannot be guaranteed, and the cage after riveting cannot be guaranteed to have a certain strength. Inconvenience for subsequent finishing;

[0007] 3) The efficiency of riveting is low, wasting manpower and materials
