Rivet pressing device of steering gear oil cylinder assembly

Abstract

The invention discloses a rivet pressing device of a steering gear oil cylinder assembly. The rivet pressing device comprises a base, a shell positioning seat arranged on the base and a support frame, wherein the support frame is provided with a pressing block for driving an oil cylinder positioning rod to be pressed into an upper port of a steering gear oil cylinder, a steering gear shell positioning mechanism, a steering gear shell and steering gear oil cylinder clamping and riveting mechanism and a steering gear oil cylinder nozzle limiting mechanism. With the structure, the device disclosed by the invention has the following advantages: (1) the steering gear shell is positioned through the shell positioning seat and a shell positioning rod while the oil cylinder is positioned by an oil cylinder positioning rod; and the rivet pressing of the steering gear oil cylinder and the steering gear shell is performed through the down pressing of the pressing block while the rivet pressing angle and position are accurate and the rivet pressing coaxiality is exact; and (2) the inner wall shape of the upper end of the steering gear oil cylinder is matched with the outer wall shape of the end part of the oil cylinder positioning rod, and the inner wall shape of the lower end of the steering gear shell is matched with the outer wall shape of a support boss of the shell positioning seat; and if the type of the steering gear oil cylinder or the steering gear shell is taken by mistake, the steering gear oil cylinder or the steering gear shell cannot be assembled, thereby avoiding wrong assembly of the oil cylinder and the shell.

Description

technical field [0001] The invention relates to the technical field of steering gear, in particular to a riveting device and a riveting method for a steering gear oil cylinder assembly. Background technique [0002] At present, the common riveting method of the steering oil cylinder assembly is manual riveting. It is difficult to control the riveting angle and riveting position accurately, and the coaxiality of the riveting of the oil cylinder and the shell cannot be guaranteed. The body is also prone to misassembly resulting in a mismatch. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a riveting device for the steering oil cylinder assembly with accurate riveting angle and position, precise riveting coaxiality, and error-proof assembly of the oil cylinder and the housing in view of the deficiencies in the prior art and its pressure riveting method. [0004] In order to solve the above technical problems, the...
