Abstract

The invention discloses an oil cylinder connecting pipe coaxiality measuring gauge, which comprises a length measurer and a positioning body which is cylindrical as a whole, wherein a measuring hole is formed in the middle of the positioning body and is coaxial with the positioning body, a transverse hole is formed in the positioning body and is formed in the horizontal direction, the transverse hole is communicated with the measuring hole, a pressure head and a first compression spring are arranged in the transverse hole, one end of the first compression spring abuts against the hole wall ofthe transverse hole, the other end of the first compression spring abuts against one end of the pressure head, and the other end of the pressure head partially extends into the measuring hole; and thepositioning body further comprises a longitudinal hole formed in the positioning body, and the end, away from the measuring hole, of the transverse hole vertically extends upwards to form the longitudinal hole. The oil cylinder connecting pipe coaxiality measuring gauge aims to solve the technical problem that no special coaxiality detection equipment is available in the prior art, so that the coaxiality of a connecting pipe and a bearing mounting hole can be conveniently and quickly detected.

Description

technical field [0001] The invention belongs to the technical field of testing tools used in the manufacturing process of gearboxes, and in particular relates to a testing tool for measuring coaxiality of an oil cylinder joint. Background technique [0002] In the manufacturing process of the transmission, after the oil cylinder connecting pipe is press-fitted, it is inconvenient to measure the coaxiality of the connecting pipe and the bearing hole of the rear housing. There is no special coaxiality testing equipment in the prior art to realize the convenient and quick inspection of the connecting pipe and the bearing installation. Concentricity of the hole. Contents of the invention [0003] (1) Technical problems to be solved [0004] Based on this, the present invention proposes a measuring tool for the coaxiality of the oil cylinder connecting pipe, which aims to solve the problem that there is no special coaxiality testing equipment in the prior art, which can realiz...
