Problems solved by technology

However, this method requires the cooperation of the mould, and usually the riveting object is an easy-to-operate flat plate component. For components such as automobile shock absorbers that need to be connected on a cylindrical oil storage cylinder, the existing flat mold cannot do this. Require
Moreover, the number of riveting points of different riveting parts is different. At this time, the position of the mold needs to be changed frequently for each riveting with the conventional method, and the operation process is cumbersome.

Abstract

The invention provides a processing device applied to rivet connection of a shock absorber. The processing device comprises a fixed supporting base, a die for carrying a pressing rivet, a first positioning assembly arranged at one end of the die to position the die radially and a second positioning assembly arranged at the other end of the die to position the die axially; one end of the die is provided with a plurality of radial positioning parts while the other end of the die is provided with an axial positioning groove, and the acting end of the first positioning assembly is provided with radial positioning corresponding parts equal to the radial positioning parts in quantity; and the acting end of the second positioning assembly is provided with a jacking head arranged corresponding tothe radial positioning groove. The processing device is to expand radially under the action of pressures of the axial positioning device and the radial positioning device to be attached to the inner wall of an oil storage barrel of the shock absorber so as to achieve rivet connection of a bended surface. In addition, the used die with various models can be suitable for rivet connection demands ofdifferent components.

Description

technical field [0001] The invention relates to a processing device applied to the rivet connection of a shock absorber, belonging to the technical field of riveting. Background technique [0002] A shock absorber is a damping device that can be used to reduce shocks. It is widely used in the automotive field and is of great help to improve the ride comfort of a car. With the rapid development of the automobile industry, the auto parts industry has also grown simultaneously. At the same time, the market competition in the shock absorber industry will become more intense, and higher requirements are placed on the shock absorber, which requires the shock absorber to have Higher strength, durability, and sealing. At the same time, the manufacturing of shock absorbers pays more and more attention to environmental protection and personal safety issues. [0003] The components of automobile shock absorbers include spring discs, stabilizer bar brackets, U-shaped brackets and posit...
