Shifting fork lining press-in tool

Abstract

The invention discloses a shifting fork lining press-in tool. The shifting fork lining press-in tool comprises a base (4) installed on a press working table, a positioning column (3) and a downwards-pressing column (1), and the positioning column (3) and the downwards-pressing column (1) are fixed to the base (4); the cross section of the positioning column (3) is in a step shape, and the positioning column (3) comprises an upper section, a middle section and a lower section with gradually-increased cross sections, wherein the diameter of the upper section is smaller than the inner diameter of linings, and the diameter of the middle section is larger than the inner diameter of the linings; the shifting fork lining press-in tool further comprises a guide column (2) located between the positioning column (3) and the downwards-pressing column (1), the guide column (2) comprises an upper section, a middle section and a lower section with gradually-decreased cross sections, wherein the diameter of the lower section is smaller than the inner diameter of the linings, and the diameter of the middle section is larger than the inner diameter of the linings; and the axis lines of the downwards-pressing column (1), the guide column (2) and the positioning column (3) are coincident. According to the shifting fork lining press-in tool, the guide column is arranged between the downwards-pressing column and the positioning column, and the upper lining and the lower lining are synchronously pressed into shifting fork shaft holes.

Description

technical field [0001] The invention relates to the technical field of motor vehicle transmission, relates to a shift fork and a bush used to reduce the wear of the shift fork hole and the shift fork hole shaft, and in particular to a device that can rapidly press two shift fork bushes into the shift fork shaft hole synchronously. device. Background technique [0002] The shift fork is often used in conjunction with the shift fork shaft. In order to reduce the wear between the shift fork and the shaft, it is necessary to install a bush in the shaft hole of the shift fork. In view of the long shaft hole of the shift fork, the process of installing the long bush as a whole is difficult and difficult. It is uneconomical, and a workaround is usually adopted to install a short bushing at the upper and lower ends of the shaft hole. [0003] In the prior art, due to the limitation of the tooling, it is usually divided into two processes to press in separately, first press in the b...

Problems solved by technology

[0003] In the prior art, due to the limitation of the tooling, it is usually divided into two processes to press in separately, first press in the bottom bushing, and then press in the top bushing, which requires two presses, two sets of auxiliary tools and at least two workers , not only uneconomical but also a high rate of defective products
