Description

Technical Field

[0001] The utility model relates to the technical field of automobile brake disc detection equipment, in particular to a diameter detection equipment for processing automobile brake structure discs. Background Art

[0002] The brake disc is a metal disc made of alloy steel and fixed on the wheel, rotating with the wheel. When the vehicle is driving, the brake caliper clamps the brake disc to slow down or stop the vehicle. Generally, there are round holes on the brake disc, which is used to reduce weight and increase friction. There are many types of brake discs, which are characterized by thin walls, and the disc and the center are formed by sand cores. Different types of brake discs have differences in disc diameter, disc thickness and the gap between the two discs. The thickness and height of the disc hub are also different. In the process of processing and producing automobile brake discs, various equipment needs to be used for auxiliary work to improve the production efficiency of brake discs and extend the service life of brake discs. Among them, the "a kind of automobile brake disc processing fixture with stable structure" disclosed by the application number "CN214642962U" has solved the existing automobile brake disc processing fixture. When tightening the brake disc, it will cause obstruction to the processing, and the rotation cannot be controlled for processing. The processing range is relatively small, and the mobile operation is inconvenient, which is not conducive to adjusting the position of the automobile brake disc to adapt to different After further searching, it was found that the "heat dissipation structure of an automobile brake disc" disclosed by the announcement number "CN211259432U" effectively solved the technical disadvantages of the existing brake disc, which generates a lot of heat due to friction during braking, and it takes a certain amount of time to dissipate heat by relying on the brake disc itself, and the heat dissipation is not efficient. However, in actual use, automobile brake discs with similar structures still have many defects, such as: there are fewer detection and measurement parameters, which is not convenient for classifying and arranging brake discs, and there is no adjustment and measurement function for brake discs of different sizes. Therefore, it is necessary to design a diameter detection equipment for automobile brake structure disc processing. Utility Model Content
