Press-riveting device and method for steering engine oil cylinder assembly

Abstract

The invention discloses a press-riveting device for a steering engine oil cylinder assembly. The press-riveting device comprises a base, a shell positioning base and a supporting frame, wherein the shell positioning base is arranged on the base. A pressing block, a steering engine shell positioning mechanism, a steering engine shell and steering engine oil cylinder clamping and riveting mechanism and a steering engine oil cylinder oil nozzle limiting mechanism are arranged on the supporting frame, wherein the pressing block drives an oil cylinder positioning rod to be pressed into an upper port of a steering engine oil cylinder. By the adoption of the structure, the press-riveting device has the advantages that a steering engine shell is positioned through the shell positioning base and a shell positioning rod, an oil cylinder is positioned through an oil cylinder positioning rod, press riveting of the steering engine oil cylinder and the steering engine shell is carried out by pressing down the pressing block, the press-riveting angle and position are accurate, and the press-riveting coaxiality is accurate; the shape of the inner wall of the upper end of the steering engine oil cylinder is matched with the shape of the outer wall of the end of the oil cylinder positioning rod, and the shape of the inner wall of the lower end of the steering engine shell is matched with the shape of the outer wall of a supporting boss of the shell positioning base, so that assembling is not completed when a wrong model of the steering engine oil cylinder or a wrong model of the steering engine shell is chosen, and mistaken assembling of the oil cylinder and the shell is avoided.

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...
