Bush press fitting and interference force detection device for brake lining supports and method

Abstract

The invention discloses a bush press fitting and interference force detection device for brake lining supports and a method. The device comprises a rack, a follow-up stopping mechanism, a brake liningsupport feeding mechanism, power mechanisms and an industrial personal computer, wherein the follow-up stopping mechanism, the brake lining support feeding mechanism, the power mechanisms and the industrial personal computer are arranged on the rack; the brake lining support feeding mechanism comprises a supporting plate used for allowing the brake lining supports to be arranged; the power mechanisms comprise pulling and pressing shaft rods and power output units for driving the pulling and pressing shaft rods to reciprocate, and limiting grooves are formed in one ends of the pulling and pressing shaft rods; the follow-up stopping mechanism comprises stopping pieces and a driving mechanism used for changing the positions of the stopping pieces, clamping parts matched with the limiting grooves are arranged at one ends of the stopping pieces, and the clamping parts are provided with first surfaces and second surfaces which are opposite in the thickness direction; and when the pulling and pressing shaft rods move in a first direction, the first surfaces can press bushes located on convex lugs at the inner side, and when the pulling and pressing shaft rods move in a second direction opposite to the first direction, the second surfaces can press bushes located on convex lugs at the outer side. The bush press fitting and interference force detection device for the brake lining supports and the method can improve press fitting quality, efficiency and automation degree.

Description

technical field [0001] The invention relates to the technical field of maintenance of foundation brake devices of railway locomotives, and in particular to a device and method for press-fitting and interference force detection of brake pad bushings. Background technique [0002] The statements in this section only provide background information related to the present disclosure and may not constitute prior art. [0003] The brake caliper unit brake pad holder is a part of the brake caliper unit, such as figure 1 As shown, the brake pad carrier assembly 1 is hingedly connected with the longitudinal rod 3 through the bush 2 press-fitted thereon. The braking force of the brake caliper is transmitted to the brake pad carrier 34 through the brake lever 4, and finally acts on the brake disc. Brake holder 34 and bushing 2 adopt the interference connection method, and the friction force of the interference connection is related to many factors such as the size tolerance of the bus...

AI Technical Summary

Problems solved by technology

[0005] At present, the four bushes 2 on the brake pad holder 34 are all press-fitted on one side. When the two outer bushes 2 are press-fitted, due to the large bending moment, if the positioning is not firm, the brake pad holder 34 as a whole is easy to Deformation will affect product quality

In addition, one-sided press-fitting is used to complete the press-fitting or testing of the four bushings 2, which requires the hydraulic cylinder to drive the pressure shaft to make two reciprocating strokes, and the press-fitting efficiency is low
