Description

Technical Field

[0001] The utility model relates to the technical field of brake disc detection equipment, in particular to a brake disc dynamic balancing quick clamp. 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. During the production process of the brake disc, its dynamic balance needs to be tested, and during the testing process, a corresponding fixture is needed to clamp and fix the brake disc.

[0003] The existing brake disc dynamic balancing quick clamp uses a three-jaw chuck to clamp and fix the brake disc during use. When testing the outside of the brake disc, it is necessary to use an internal locking method, and when testing the inside of the brake disc, it is necessary to use an external locking method. These two locking methods cannot be implemented on the same chuck, which leads to a low utilization rate, affecting the applicability and use effect of the clamp. Therefore, a brake disc dynamic balancing quick clamp is urgently needed to solve the above problems. Utility Model Content

[0025] The screw block 4 is screwed onto the bidirectional screw rod 7 via a thread. The specification of the screw block 4 matches that of the limiting groove 5. The screw block 4 is slidably connected to the limiting groove 5.
