Description

Technical Field

[0001] The utility model relates to the technical field of brake disc fixing tooling, in particular to a high-efficiency brake disc fixing tooling. Background Art

[0002] The brake disc is the friction element of a disc brake, rotating synchronously with the wheel. When the vehicle needs to slow down or stop, the caliper clamps the disc, generating braking force through friction to slow the vehicle down or stop. During brake disc machining operations, it is usually necessary to clamp the disc to prevent it from shifting during processing. This clamping operation typically requires a corresponding fixture. There are many types of fixtures on the market, and most of them utilize a pneumatic cylinder. The telescopic shaft on the cylinder extends, driving a clamping block to clamp the disc.

[0003] However, the thickness of the clamping blocks on this type of fixture is generally fixed, and the overall thickness cannot be increased by adding a corresponding number of clamping blocks as needed. If the clamping blocks are initially thicker, they may obstruct the side machining of the brake disc. When the clamping blocks are thinner, the fixed contact area between the clamping blocks and the brake disc is smaller, making it difficult to achieve a stable clamping effect, thus affecting its performance. In view of this, we have proposed a highly efficient brake disc fixing fixture. Utility Model Content
