Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a fixture for finishing the front and back inner and outer holes of brake structural parts. Background Art

[0002] When cutting the brake base, the brake base forging needs to be clamped and fixed by a processing fixture. Due to the special shape of the brake base, the positioning accuracy requirements are high, there are many processing features and the front and back sides need to be machined. When fixing the brake base, it is difficult to clamp and position the brake base efficiently and accurately by relying on traditional fixtures. Manual calibration is required, and the operation is complicated and takes a lot of positioning and calibration time. It is very inconvenient to use, and usually needs to be coordinated with a multi-channel hydraulic station to achieve multi-action clamping. The existing processing fixtures are mostly single-sided processing, and can only process the internal control of one side of the plane at a time. Multiple replacement of workpieces will increase the processing interval time of the workpiece and reduce the processing efficiency of the workpiece. At the same time, it will increase the product precision error and the scrap rate, which will greatly increase the production cost. Utility Model Content
