The invention discloses a scroll plate of a high-precision scroll compressor and a manufacturing method thereof. The scroll plate comprises a stationary scroll plate body and a movable scroll plate body. The stationary scroll plate body is provided with a spiral groove, the movable scroll plate body is provided with a scroll strip, and the scroll strip is matched with the spiral groove. The top surface of the stationary scroll plate body is provided with a positioning groove which is internally provided with a vibration damper. The inner side surface of the spiral groove is provided with a stroke groove. The outer side surface of the scroll strip is provided with a flexible compensation strip which is matched with the stroke groove. The method includes the steps of casting the stationary scroll plate body, casting the movable scroll plate body, machining the flexible compensation strip, mounting the vibration damper, and assembling the whole scroll plate. The manufacturing method is simple, the machining precision is high, and the requirement for machining the scroll plate of the high-precision scroll compressor can be met; and under the condition that the machining precision of the spiral groove and the scroll strip is guaranteed, a cutter is transformed reasonably, so that machining efficiency is improved, and cost is reduced.
Description
technical field [0001] The invention relates to a scroll disc of a high-precision scroll compressor and a manufacturing method thereof. Background technique [0002] The core component of the scroll compressor is the scroll. The compression of the gas by the scroll compressor is through the relative movement of the two meshing movable scrolls and the fixed scroll. Therefore, the manufacturing accuracy of the scroll wall shape of the scroll directly affects the working performance of the scroll compressor. [0003] When the scroll in the prior art is working, since there is no axial compensation function, it is easy to cause a large impact force between the fixed scroll and the movable scroll during air intake and exhaust, and it is easy to cause the wear of the scroll , and the noise is high, and the processing of the vortex profile is more difficult, and the vortex bar cannot be well matched with the spiral groove, and the service life is short.
