A processing tool for the scroll disk of a scroll compressor

Abstract

The invention discloses a processing tool for a scroll disc of a scroll compressor, which relates to the field of scroll compressors. A clamping groove is arranged on the base of the clamp, and a pressing plate is arranged in the holding groove. The pressing plate is connected with the main shaft of the cylinder, and the main shaft of the cylinder is arranged on In the fixture base, two pins are symmetrically arranged on both sides of the upper end surface of the fixture base, and pin holes are arranged on the lower end surface of the scroll step corresponding to the positions of the pins, and the scroll step and the upper end surface of the fixture base are locked together. Then, the upper end of the scroll step is provided with a scroll, and the lower end of the sleeve is provided with a sleeve keyway, and the sleeve is sleeved on the fixture base through the sleeve keyway corresponding to the position of the pressure plate, and the upper end of the sleeve and the scroll The steps press against each other. It adopts the method of pulling down the cylinder to lock and the positioning of the scroll to avoid the error of repeated positioning. The processing efficiency is improved, and the processing consistency is extremely high.

Description

Technical field: [0001] The invention relates to a processing tool for a scroll disk of a scroll compressor, belonging to the technical field of scroll compressors. Background technique: [0002] The scroll needs to be milled on the machining center with the involute of the corrected circle. It is necessary to ensure that the center of the scroll line and the center of the scroll are in the same center. In this way, there are two requirements for the tooling: positioning and clamping. Pack. [0003] The previous clamping method used a hydraulic or pneumatic high-precision chuck to clamp the maximum diameter of the scroll, and then processed after locking. This process is likely to cause repeated positioning errors of the scroll during clamping, poor consistency of the workpiece, and clamping. The workpiece is damaged, the parallelism of the scroll is very poor, the clamping has high requirements for the operator, the tooling is expensive, and the existing scroll is made of ...

[0003] The previous clamping method used a hydraulic or pneumatic high-precision chuck to clamp the maximum diameter of the scroll, and then processed after locking. This process is likely to cause repeated positioning errors of the scroll during clamping, poor consistency of the workpiece, and clamping. The workpiece is damaged, the parallelism of the scroll is very poor, the clamping has high requirements for the operator, the tooling is expensive, and the existing scroll is made of aluminum alloy, which is not only soft in texture, but also easy to deform, which is difficult to meet the current requirements. production demand
