Machining tooling for scroll plate of scroll compressor

Abstract

The invention discloses a machining tooling for a scroll plate of a scroll compressor, and relates to the field of the scroll compressor. A clamp base is provided with a clamping groove; a pressing plate is arranged in the clamping groove; the pressing plate is connected to a main shaft of an air cylinder; the main shaft of the air cylinder is arranged in the clamp base; two sides of the upper end surface of the clamp base are provided with two symmetrical pins; pin holes are formed in positions corresponding to the pins, of the lower end surface of a the scroll plate step; the scroll plate step is snapped onto the upper end surface of the clamp base; the upper end of the scroll plate step is provided with the scroll plate; the lower end of a sleeve is provided with a sleeve key groove; the sleeve sleeves the clamp base through a position corresponding to the pressing plate, of the sleeve key groove; and the upper end of the sleeve is tightly pressed the scroll plate step. According to the machining tooling, through an air cylinder pull-down locking manner and a scroll plate positioning manner, errors of repeated positioning can be avoided; and the machining tooling can conveniently and rapidly clamps the scroll plates, can clamp a plurality of the scroll plates at the same time, reduce the times of changing tools due to machine tool idling, and improve the machining efficiency, and is high in machining consistency.

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
