Problems solved by technology

The smaller the step size setting, the larger the memory space required to maintain the calculation of the machining center, which will lead to a decrease in the processing speed
At present, there is no method for obtaining scroll profiles with low processing cost and high processing accuracy.

Abstract

The invention discloses a method for machining a molded line of a scroll plate, and relates to the technical field of mechanical machining. The scroll plate is provided with an end plate and a scroll wall thereon, wherein an annular groove is formed in the periphery of the end plate; and a positioning hole is formed in the lower end face of the end plate. According to the method, a clamp for machining the molded line of the scroll plate is fixedly arranged on a workbench of a vertical machining center; the scroll plate is fixed on the clamp for machining the molded line of the scroll plate by a spring check ring; according to rough machining and semifinishing, a cutter feeding instruction of a cutter is set into fifth-degree step lengths; and according to finish machining, a cutter feeding instruction of the cutter is set into first-degree step lengths. Compared with the prior art, the method has the advantages that the cutter feeding instruction of the cutter is set from large to small, the machining accuracy is improved gradually, and machining equipment and the cutter are used reasonably while the machining accuracy of the molded line is ensured, so that the efficiency of machining the molded line is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing methods, in particular to a method for processing a scroll profile of a scroll disk of a scroll compressor. Background technique [0002] The core component of a scroll compressor is the scroll, which has an end plate and a scroll wall thereon. The compression of the gas by the scroll compressor is achieved by the relative movement of the two scrolls that mesh with each other, and the seal line of the scroll wall of the two scrolls is pushed from the outside to the inside; therefore, the scroll wall of the scroll The manufacturing accuracy of the molding line directly affects the working performance of the scroll compressor. There is a profile formed by connecting arcs and involutes of circles. The profile of this vortex profile is required to be 0.01 mm, which has particularly high requirements for processing equipment. On the vertical machining center with linear and circular int...
