Press riveting device of steering engine hydraulic cylinder assembly

Abstract

The invention discloses a press riveting device of steering engine hydraulic cylinder assembly. The press riveting device of steering engine hydraulic cylinder assembly comprises a base, a shell positioning seat which is installed on the base, and a support frame. The support frame is provided with a pressing block which presses a hydraulic cylinder positioning rod into a steering engine hydraulic cylinder upper port, a steering engine shell positioning mechanism, a clamp riveting mechanism of the steering engine shell and the steering engine hydraulic cylinder, and a steering engine hydraulic cylinder nozzle limiting mechanism. By employing such a structure, the press riveting device of steering engine hydraulic cylinder assembly has the advantages as follows: 1, the steering engine shell is positioned via the shell positioning seat and the shell positioning rod; the hydraulic cylinder is positioned via the hydraulic cylinder positioning rod; the steering engine hydraulic cylinder and the steering engine shell are press riveted by the pressure of the pressing block; therefore the press riveting angle, the press riveting position, and the press riveting coaxiality are precise. 2, the inner wall shape at the upper end of the steering engine hydraulic cylinder is matched with the outer wall shape at the end portion of the hydraulic cylinder positioning rod; and the inner wall shape at the lower end of the steering engine shell is matched with the outer wall shape of the support protrusion of the shell positioning seat; therefore, if the model of the steering engine hydraulic cylinder or the model of the steering engine shell is not correct, the assembling cannot be done, thus avoiding mismatch of the hydraulic 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 . [0004] In order to solve the above technical problems, the technical solution of the prese...
