Press riveting device for oil cylinder assembly of steering engine

Abstract

The invention discloses a press riveting device for an oil cylinder assembly of a steering engine. The device comprises a base, a housing positioning seat arranged on the base, and a supporting frame; a pressing block, a housing positioning mechanism of the steering engine, a housing and oil cylinder clamping riveting mechanism of the steering engine, a oil cylinder nozzle limiting mechanism of the steering engine are arranged on the supporting frame, wherein the pressing block is used for driving an oil cylinder positioning rod to be pressed into an upper end port in an oil cylinder of the steering engine. The press riveting device adopting the structure above has the advantages that 1, the housing of the steering engine is positioned through the housing positioning seat and the housing positioning rod, the oil cylinder is positioned through the oil cylinder positioning rod, the pressing block is downwards pressed to realize press riveting for the steering engine oil cylinder and the steering engine housing, the press riveting angle and position are accurate, and the coaxiality in press riveting is precise; 2, the inner wall of the upper end of the steering engine oil cylinder is matched with the outer wall of the end part of the oil cylinder positioning rod by the shape, the inner wall of the lower end of the steering engine housing is matched with the outer wall of a supporting boss of the housing positioning seat by the shape, thus steering engine oil cylinder or steering engine housing of inaccurate model cannot be assembled, and as a result, the assembling error of the oil cylinder and the housing can be prevented.

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...
