Clutch shift fork assembly riveting process

Abstract

The invention discloses a clutch fork assembly riveting technique. The clutch fork assembly riveting technique comprises the steps that firstly, a riveting clamp is manufactured, the riveting clamp comprises a base, a combined installation base and a fork limiting block are fixedly arranged on the base, a fork clamping piece positioning column and a rivet positioning column are fixedly arranged on the combined installation base, the fork limiting block, the fork clamping piece positioning column and the rivet positioning column are sequentially arranged on the same line from front to back at intervals, the cross section of the fork limiting block is in the shape of an inverted T, a bolt penetrates through the step surface of the fork limiting block so as to fix the fork limiting block to the base, a hemispherical head is arranged at the top of the fork clamping piece positioning column, and a hemispherical groove is formed in the top of the rivet positioning column; secondly, the riveting clamp is fixed to a working table through the base; thirdly, a workpiece is clamped; and fourthly, a clutch fork, a fork clamping piece and a rivet are fixed together in a riveted mode through a riveting device. According to the clutch fork assembly riveting technique, the riveting precision is high, and manual correction is not needed in the later stage; meanwhile, looseness and disengagement of the fork clamping piece can be avoided after the fork clamping piece is riveted.

Description

technical field [0001] The invention relates to the technical field of riveting technology, in particular to a riveting technology for riveting a clutch shift fork assembly. Background technique [0002] The clutch shift fork assembly is formed by riveting the clutch shift fork and the shift fork card through rivets. combine figure 1 , figure 2 As shown, the existing riveting fixture includes a base 1 on which a rivet positioning column 5 and a shift fork limit block 3 are fixed. The top of the rivet positioning column 5 has a spherical groove, and the cross section of the shift fork limit block 3 is "convex". When riveting, place the hemispherical head of the rivet C in the spherical groove of the rivet positioning column 5 first, and then place the clutch shift fork A. Clamp the word "convex", and finally place the shift fork card B on the clutch shift fork A. At this time, the riveted end of the rivet C passes through the rivet hole on the clutch shift fork A and the...

Problems solved by technology

[0003] The main problems in the actual use of the above riveting process are: (1) the shift fork card B is only limited by the rivet C, and it may rotate slightly around the axis of the rivet C during riveting, and the positioning is inaccurate, resulting in the shift fork The gap B1 at the end of the card B is misaligned with the middle hole A1 of the clutch fork A, which needs to be corrected manually in the subsequent process, and will cause the fork card B to loosen; (2) The riveted end is located on the side of the fork card B. When the length is short, the shift fork card B is easy to fall off
