Clamp for inspecting angle of twisting joint notch

Abstract

The invention belongs to the field of aeronautic equipment manufacturing, and relates to a clamp for inspecting the angle of a twisting joint notch. The clamp for inspecting the angle of the twistingjoint notch comprises a base, a positioning plate, an inspecting block, a shaft pin, a plug pin, a first positioning pin and a second positioning pin; a ribbed plate is arranged on the base, and usedfor supporting other parts, the lower end of the positioning plate is in screw joint to the inclined ribbed plate, a round through hole is formed in the upper end of the positioning plate, and cooperation with a part notch is achieved; the first positioning pin is inserted into the round through hole of the positioning plate and a part base hole, the lower end of the inspection blcok is connectedwith the base through the shaft pin, a round through hole is formed in the upper end of the inspection block, and is matched with the other notch of the part, the plug pin is inserted into the lower end of the inspection block, and the state of the inspection block is stable. The second positioning pin is inserted into the round through hole of the inspection block and the other base hole of the part, and angle inspection of the part is achieved. The clamp is simple in structure, ingenious in appearance, and capable of effectively detecting the machining angle, it is ensured that the product percent of pass of delivery parts is 100%, and the inspection auxiliary time is shortened.

Description

technical field [0001] The invention belongs to the field of aviation equipment manufacturing, and relates to a fixture for testing the angle of a notch of a twisted joint. Background technique [0002] In the field of aerospace machining, whether it is military aircraft or civil aircraft, there are a large number of special-shaped parts with notch features. Such parts have different shapes, and the processing technology is not good. It is difficult to guarantee the final size requirements, and the pass rate is relatively low. However, the design basis and processing basis of most of these products are hole elements, which provides a new solution for checking the notch angle. [0003] This type of part is in the shape of a twisted joint, and the measured element is in a cross state. It cannot be accurately measured by the existing general-purpose measuring tools. It can only be confirmed that the part meets the use requirements after a trial assembly of the parts assembled ...

AI Technical Summary

Problems solved by technology

[0003] This type of part is in the shape of a twisted joint, and the measured element is in a cross state. It cannot be accurately measured by the existing general-purpose measuring tools. It can only be confirmed that the part meets the use requirements after a trial assembly of the parts assembled with it. low production efficiency

The measured notch angle of the part selected this time is 41.24°, which is the assembly angle of the part. If the angle is too small or too large, it will cause the consequence that the part cannot work normally after assembly.
