Testing fixture of position accuracy of back hole of exhaust pipe

Abstract

The invention discloses a testing fixture of position accuracy of a back hole of an exhaust pipe. The testing fixture includes a base plate; cushion blocks are respectively arranged at a left end and a right end of the base plate; cylindrical positioning pins are arranged on all the cushion blocks; supports are arranged at a left end and a right end of an upper edge of the base plate and an intermediate section of a lower edge of the base plate; guide blocks are arranged at top ends of all the supports; plug holes are arranged on the guide blocks; and plugs are arranged inside the plug holes. According to the invention, the testing fixture has advantages of simple structure, convenient detection, fastness, and high detection efficiency.

Description

technical field [0001] The invention relates to mechanical processing equipment, in particular to a tool for checking the position of the back hole of an exhaust pipe. Background technique [0002] At present, in the prior art, the fixtures for processing exhaust pipes generally have technical problems such as processing difficulties and low efficiency. The reason is that the shape of the exhaust pipe is complicated, and when processing the exhaust pipe, all Blank parts are difficult to clamp. If you want to clamp, you must set multiple clamping points for clamping and add more auxiliary workpieces. However, there will be too many clamping points, which will cause the exhaust pipe to be clamped and deformed. But not up to the process needs. Contents of the invention [0003] The invention provides a convenient and simple detection tool with high detection efficiency for the position degree of the back hole of the exhaust pipe. [0004] The present invention solves tech...

[0002] At present, in the prior art, the fixtures for processing the exhaust pipe generally have technical problems such as processing difficulties and low efficiency. The reason is that the exhaust pipe The shape is complex, and when the exhaust pipe is processed, it is a blank part, which is difficult to clamp. If you want to clamp, you must set multiple clamping points for clamping and add more auxiliary workpieces, but this There will be too many clamping points, which will cause the exhaust pipe to be clamped and deformed and fail to meet the process requirements
