Problems solved by technology

However, because there is a gap between the bushing and the indenter, the two bushings and the bushing hole are not in the same axis when they are pressed in, resulting in either the bushing being crooked and crushed, or the bushing hole being crushed

Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] An embodiment of the present invention provides a double-sided pressing bushing mechanism of a shift fork shaft, which is suitable for pressing the bushing into the bushing hole of the bushing.

[0024] Such as figure 1 , 2 As shown, the double-sided pressing bushing mechanism 100 of the shift fork shaft in this embodiment includes: a pressing assembly 1 and a power part 2 .

[0025] The press assembly 1 includes: a transmission push rod 11 and a plur...

Abstract

The invention provides a shifting fork shaft double-face bush pressing mechanism and device. The shifting fork shaft double-face bush pressing mechanism comprises a press fitting assembly and a powerpart. The press fitting assembly comprises a transmission push rod and a plurality of sliding blocks, one end of the transmission push rod is in transmission connection with the power part and is driven by the power part to move in the axial direction, and the other end of the transmission push rod is a conical end; and the plurality of sliding blocks are distributed on the periphery of the conical end, move in the axial direction of the transmission push rod and perform radial movement along the conical surface of the conical end. According to the shifting fork shaft double-face bush pressingmechanism, the transmission push rod and the plurality of sliding blocks are adopted, the transmission push rod can push the sliding blocks to stretch out in the radial direction in the press fittingprocess, a shaft sleeve hole and a bush are aligned, the coaxiality is guaranteed, and the bush is pressed into the shaft sleeve hole; and when the transmission push rod retreats, the plurality of sliding blocks retreat in the radial direction and are conveniently separated from the bush, and the problem that in the prior art, the bush or the shaft sleeve hole is crushed is solved.

Description

technical field [0001] The invention relates to the technical field of press-fitting of shift fork bushings, in particular to a double-sided pressing bushing mechanism and device for a shift fork shaft. Background technique [0002] At present, the shift fork of the automobile transmission has a shaft sleeve, and the shaft sleeve is arranged axially through, and a bushing is respectively installed in the shaft sleeve holes at both ends, and the bushing is fitted in the shaft sleeve hole with interference. This bushing can be used to reduce the friction between the bushing and the shaft. In the existing press-fitting method, the bushing is placed on the pressing head, and the bushing is used as a guide to press the bushing into the shaft sleeve hole. However, because there is a gap between the bushing and the indenter, the two bushings are not coaxial with the bushing hole when they are pressed in, resulting in either the bushing being crooked and crushed or the bushing hole...
