Description

Technical Field

[0001] The invention relates to the technical field of automobile parts detection, in particular to a positioning structure for linear dimension detection of automobile disc-shaped parts. Background Art

[0002] When the automobile brake disc is produced and cast, it is usually centered on the axis. This center point will have a phenomenon that one side is heavy and the other side is light. When such a disc-shaped workpiece rotates at high speed, the parabola generated is not in a circle, which causes the car to shake when it is moving. Therefore, during the processing of disc-shaped parts, the linear dimensions of the disc-shaped parts need to be tested many times to control the production qualification rate of the disc-shaped parts.

[0003] When the existing positioning structure for linear dimension detection of automotive disc-shaped parts is used, the inner circumference of the disc-shaped parts is generally pressed and positioned. During the detection of workpieces of different sizes, the angle or size of the positioning structure needs to be adjusted. Due to the use of bolt fixing technology, the loading and unloading operations are more troublesome. In addition, when the disc-shaped parts are rotated for detection, they are easily disturbed by external vibrations, which affects the accuracy of the detection. Summary of the invention
