Description

Four-axis linkage machining fixture

technical field

The invention belongs to the field of machining, in particular, the invention relates to a four-axis linkage machining fixture.

Background technique

In the existing mechanical processing field, a single three-axis clamping mode is generally adopted in the workpiece processing engineering. Fix the workpiece on the processing table first, and process the workpiece through the cutter head. Moreover, in the process of processing, the accuracy of workpiece clamping must be guaranteed to avoid errors.

However, in the process of processing, it is usually necessary to process irregular surfaces or multi-featured surfaces. In the prior art, processing can only be performed through multiple assembly and multiple processes, resulting in low processing efficiency and easy displacement. In addition, in the process of processing, it is often necessary to process multiple surfaces of the workpiece at the same time. After processing one surface, the workpiece needs to be turned over to process other surfaces. However, at present, it is generally processed multiple times by re-clamping, which is slow, inefficient and easy to shift.

Therefore, it is necessary to improve the existing clamping mode to improve the efficiency of workpiece processing and reduce processing errors.
