Riveting pressing forming device for cover plate of automobile clutch booster

Abstract

The invention discloses a riveting pressing forming device for a cover plate of an automobile clutch booster. The riveting pressing forming device for the cover plate of the automobile clutch booster comprises a base plate, wherein a positioning base is arranged on the base plate; a positioning cylinder is arranged rightly opposite to the positioning base; a pressing block is arranged on the positioning cylinder; a riveting cylinder is arranged on the base plate; the output end of the riveting cylinder is connected with the riveting assembly; a pressing cylinder is arranged below the base plate of the corresponding riveting cylinder; the output end of the pressing cylinder is connected with the pressing assembly; the riveting assembly comprises an installing base and a hinging pressing head; the installing base is fixedly installed on the base plate; the hinging pressing head are hinged with the installing base and the output end of the riveting cylinder; an installing plate is fixedly arranged on the base plate; the end part of the riveting cylinder is hinged with the installing plate; the pressing assembly comprises a pressing plate; the pressing plate is fixedly connected with the output end of the pressing cylinder vertically; and the pressing cylinder is fixed below the base plate through a fixing plate. The riveting pressing forming device for the cover plate of the automobile clutch booster has good riveting quality; in the riveting process, the damage to an electrophoretic paint layer at a cover plate forming position is avoided; the consistency of products is good; and the production efficiency is high.

Description

technical field [0001] The invention relates to the field of auto parts processing, in particular to a riveting forming device between a cover plate and a main body of an auto clutch booster. Background technique [0002] The clutch is used very frequently when the car is running, and the working conditions of the vehicle where the booster is located are relatively harsh. The cover plate of the traditional automobile clutch booster is fixed on the main body by screws, which is easy to loosen during operation and will cause random disassembly. The present inventor has invented a kind of cover plate fixing method of automobile clutch booster, as figure 1 As shown, a vertical fixing flap 21 is provided along the edge of the cover plate 2, and then the head of the fixing flap is bent on the normal surface of the main body 1 by means of riveting. In this structure, the cover plate 2 is riveted on the main body 1 to achieve permanent fixation without random disassembly, and the ...

AI Technical Summary

Problems solved by technology

In the riveting of the fixed flap 21 of the cover plate 2, a single beating method is adopted. This method has low work efficiency, and the electrophoretic paint layer on the surface of the cover plate caused by riveting is peeled off, and the corrosion resistance and weather resistance are poor. Due to the uneven stress in the force, the riveting part of the clutch booster will break early during use, causing the dust cover to fall off early, and the dust in the air will enter the cylinder of the booster

For example: cement mixer trucks often run on the construction site, mud and dust are easily sucked into the cylinder, causing early wear of the piston Y-ring, resulting in air leakage from the large piston, and failure of the clutch booster, resulting in a shorter service life of the entire clutch booster
