AI Technical Summary

Technical Problem

Existing technologies make it difficult to efficiently detect the coaxiality and position of special-shaped structural parts, especially special-shaped parts with narrow surfaces and susceptible to interference, resulting in low detection efficiency.

Method used

The device for detecting special-shaped structural parts adopts a non-meter reading or non-measurement method. Through the combination of limit blocks, test block components and positioning pins, rapid detection is achieved. Conventional cylindrical holes are used as reference holes instead of elliptical holes, which reduces processing difficulty and improves detection accuracy.

Benefits of technology

The coaxiality and position detection efficiency of special-shaped parts is improved, the difficulty of measuring tool processing is reduced, the detection accuracy is improved, and the problem of poor processing accuracy of elliptical holes is avoided.

Abstract

The special-shaped structural member detection device is suitable for rapid detection of coaxiality and location degree of a special-shaped part and comprises a body and a test block assembly, a limiting block is arranged at the edge position of the inner side face of the body and used for limiting movement of the special-shaped part in a notch, a first hole is formed in the body, and a second hole is formed in the body and used for limiting movement of the special-shaped part in the notch. When the special-shaped part is pushed to make contact with one side face of the limiting block, the position of the assembly hole corresponds to the position of the first hole, the special-shaped part can be limited in the vertical direction and the horizontal direction after a positioning pin is inserted, and whether the position degree of the elliptical hole is qualified or not is determined through the displacement degree of the testing block assembly in the elliptical hole and the second hole. The test board is provided with a third hole in the vertical direction, after the special-shaped part is positioned, the position of the third hole corresponds to the position of the positioning hole, whether the coaxiality of the positioning hole is qualified or not is determined through the displacement degree of the detection pin penetrating through the positioning hole and the third hole, and the detection efficiency of the part is improved.
