Description

Technical Field

[0001] The utility model relates to the field of brake parts processing, in particular to a multi-station and multi-angle cutting fixture for brake structural parts. Background Art

[0002] The brake base is part of the brake of a heavy truck. During the cutting process of the brake base, the brake base forging must be clamped and fixed by a machining fixture. Due to the special shape of the brake base, the forging mold error and allowance are large. When fixing the brake base, it is difficult to clamp and position the brake base efficiently and accurately with traditional fixtures. Manual calibration is required, which is complicated and time-consuming. It is very inconvenient to use and cannot stably and efficiently remove the allowance. Existing machining fixtures are mostly single-station settings, which can only clamp and fix a single workpiece at a time. Multiple workpiece changes will increase the processing interval time of the workpiece and reduce the processing efficiency of the workpiece. If more equipment or operators are added, the production cost will be greatly increased, and the flexibility is poor.

[0003] Therefore, we have made improvements to this problem and proposed a multi-station and multi-angle cutting fixture for brake structural parts. Utility Model Content
