Description

Technical Field

[0001] The utility model relates to a five-sided rotating mirror processing fixture. Background Art

[0002] When processing the five-sided rotating mirror of the laser radar, the five-sided rotating mirror is installed on the tooling, and then the tooling is installed on the machine tool to start processing. However, the traditional tooling structure is unreasonable. During the processing, the dynamic balance of the spindle is poor after the tooling rotates, resulting in large shaking of the machine tool spindle. At the same time, the traditional tooling structure is provided with a pressure plate and a spring. The pressure plate is used to press the five-sided rotating mirror. When the workpiece needs to be rotated, the pressure plate is bounced up by the spring to realize the rotation of the workpiece. However, after the pressure plate presses the five-sided rotating mirror, it is difficult to bounce up the pressure plate by the spring in the traditional tooling structure. Each time clamping, the tooling structure needs to be removed from the machine tool, and the workpiece can be rotated only after the pressure plate is removed. Repeated clamping easily leads to the inability to guarantee the accuracy of the five sides. Utility Model Content
