A pressure riveting mechanism for steering oil cylinder assembly

Abstract

The invention discloses a rivet pressing mechanism of a steering engine cylinder assembly. The rivet pressing mechanism comprises a base, a shell positioning seat and a support rack, wherein the shell positioning seat is arranged on the base; a pressing block for driving a cylinder positioning rod to be pressed into an upper hole of a steering engine cylinder, a steering engine shell positioning mechanism, a steering engine shell and steering engine cylinder clamping and riveting mechanism, and a steering engine cylinder nozzle limiting mechanism are arranged on the support rack. By adopting the structure, the rivet pressing mechanism has the advantages that firstly, the steering engine shell is positioned through the shell positioning seat and the shell positioning rod, the cylinder is positioned through the cylinder positioning rod, the pressing block presses downwards to press the rivets of the steering engine cylinder and the steering engine shell, the rivet pressing angle and the position are accurate, and the rivet pressingcoaxiality is precise; secondly, the shape of the inner wall at the upper end of the steering engine cylinder is matched with that of the outer wall at the end part of the cylinder positioning rod, the shape of the inner wall at the lower end of the steering engine shell is matched with that of the outer wall of a support boss of the shell positioning seat, and different models of the steering engine cylinder or the steering engine shells cannot be assembled correspondingly, so that assembling mistakes of cylinders and shells are avoided.

Description

Technical field [0001] The invention relates to the technical field of steering gears, in particular to a riveting mechanism for a steering gear cylinder assembly. Background technique [0002] At present, the usual pressure riveting method for the steering engine cylinder assembly is manual pressure riveting. The pressure riveting angle and riveting position are difficult to control accurately, and the pressure riveting coaxiality of the cylinder and housing cannot be guaranteed. At the same time, the steering engine cylinder and housing The body is also easy to be assembled incorrectly and cause mismatch. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a pressure riveting mechanism for steering gear cylinder assembly with accurate pressure riveting angle and position, accurate pressure riveting coaxiality, and error-proof assembly of the oil cylinder and the shell in view of the deficiencies of the prior art . [0004] ...
