Description
Technical Field
[0001] The utility model relates to the technical field of scroll stator processing, in particular to a four-axis special punching fixture for a scroll stator. Background Art
[0002] The moving disc and the static disc in the compressor are collectively called the scroll disc. The static disc is a fixed involute, and the moving disc is an eccentric spiral involute. The two moving and static scroll discs of the double function equation type in the compressor are engaged with each other. The scroll and static disc are parts with special shapes. When punching holes in the scroll and static disc, they need to be fixed. This requires a four-axis special punching fixture for the scroll and static disc. A fixture refers to a device used to fix the processing object in the mechanical manufacturing process so that it occupies the correct position to accept construction or inspection. It is also called a fixture. In a broad sense, any device used to quickly, conveniently and safely install workpieces in any process in the process can be called a fixture.
[0003] Today's four-axis special punching fixture for scroll stator can basically meet people's needs, but there are still some problems. The specific problems are as follows:
[0004] 1. The four-axis special drilling fixture for the scroll stator needs to stably clamp the scroll stator during processing. The traditional scroll stator clamping is not stable enough, which may cause the scroll stator to deviate during drilling, affecting the drilling quality.
[0005] 2. The four-axis special punching fixture for the scroll stator is difficult to prevent the scroll stator from rotating. When punching the scroll stator, the scroll stator is prone to rotation due to vibration, resulting in the deviation of the punching position. Utility Model Content
