Fixture for detecting inner wall of automobile compressor piston

Abstract

The invention discloses a fixture for detecting an inner wall of an automobile compressor piston. The fixture comprises a base and is characterized by further comprising a support plate, a fixed base, a connecting column and a detecting head, wherein the top of the base is provided with the support plate, and one side of the support plate is outward connected with the fixed base; the front end of the fixed base is provided with the connecting column, the front end of the connecting column is provided with the detecting head, and the detecting head adopts a round detecting head; and the two sides of the round detecting head are designed into flat surfaces, and the flat surfaces are provided with blind holes. The fixture provided by the invention solves the problems in the prior art that a flange of the compressor piston is generally formed through a spring tightening device, the service life of a spring is shorter, and the spring generates deformation after being used for a long time, therefore, the detection accuracy is greatly reduced, and the detection requirement of the piston cannot be met; and the fixture provided by the invention has the advantages that the structure is simple, the use is convenient, and the fixture can rapidly and precisely detect the flange of the inner wall of the compressor piston.

Description

technical field [0001] The invention relates to a detection jig, in particular to a detection jig for the inner wall of an automobile compressor piston. Background technique [0002] There are two corresponding flanges on the inner wall of the piston of the automobile compressor. These two flanges have a great influence on whether the piston of the automobile compressor can work well. It is generally necessary to check the inner wall of the piston of the compressor before assembly. The flange is inspected to determine whether it meets the requirements of the process. At present, the detection of the piston flange of the compressor is generally completed through the spring tension mechanism, but the service life of the spring is short. After a long period of use, the spring will be deformed, which will greatly reduce the detection accuracy and cannot meet the needs of piston detection. . Contents of the invention [0003] In order to solve the problem that the piston flan...
