Aero-engine conduit conical surface coloring detection device and detection method

Abstract

The invention discloses an aero-engine conduit conical surface coloring detection device and detection method, wherein the detection device comprises a workload gauge, a detection conical surface arranged at the front end of the workload gauge, a clamping part arranged at the rear end of the workload gauge, a detection thread arranged on the workload gauge and located between the detection conicalsurface and the clamping part, and a detection gauge matched with the workload gauge; the detection conical surface is the same as a detected part in terms of conicity. The coloring detection deviceis convenient to operate and good in reliability, and effectively solves the coloring inspection problem of the sealing conical surface of the pipe end. The coloring inspection effect and the percentof pass of a pipe end sealing conical surface are guaranteed, powerful verification is provided for the sealing performance of the guide pipe assembly, and high use value is achieved.

Description

technical field [0001] The invention relates to the field of Hankong engines, in particular to an aeroengine duct tapered surface coloring detection device and detection method. Background technique [0002] The engine ducts are all over the engine body, conveying various fluids, known as the engine "vessels". Therefore, the sealing performance of the pipe end is extremely important. After the tapered surface of the pipe end seal is formed, coloring inspection must be carried out on the tapered surface to verify the forming quality of the tapered surface. The structure of the traditional cone coloring gauge is a 74° outer cone head structure. The colorant is evenly applied to the outer cone surface, and the parts and the coloring gauge are manually held to inspect the cone surface by hand. This method is greatly affected by human factors. At the same time, after the cone surface is formed, there is a small amount of springback. Under the action of a relatively small manua...

This method is greatly affected by human factors

At the same time, after the cone surface is formed, there is a small amount of springback. Under the action of a relatively small manual gripping force, the angle of the cone surface of the pipe end and the taper of the coloring gauge cannot be completely fitted, resulting in a low pass rate of the pipe end cone surface coloring inspection.
