Machining process capable of improving concentricity of machined inner circle and machined outer circle of rotor

Abstract

The invention provides a machining process capable of improving the concentricity of a machined inner circle and a machined outer circle of a rotor, and belongs to the field of rotor machining. The machining process capable of improving the concentricity of the machined inner circle and the machined outer circle of the rotor specifically includes the steps of providing a to-be-machined rotor, performing rough turning on the machined rotor, taking out the roughly-turned rotor, grinding the outer circle of the rotor, preparing a robot for feeding and discharging, boring an inner hole of the rotor, and completing the machining. The outer circle of the rotor is ground through an outer circle grinding machine first, the ground rotor is put into a four-station boring mill where operation is performed on pairs of stations, the outer circle is positioned for boring the inner hole, the machining amount is less than or equal to 0.3 mm, the cylindricity of the inner hole is less than 0.005 mm, the concentricity of the inner circle and the outer circle is less than 0.03 mm, and Cpk is greater than 1.33. The outer circle of the rotor is machined first, and then the outer circle is positioned for machining the inner hole of the rotor, so that the concentricity of the machined inner circle and the machined outer circle of the rotor can be ensured, the product scrap rate is reduce, and enterprise loss is reduced.

Description

technical field [0001] The invention belongs to the technical field of rotor processing, and in particular relates to a processing technology capable of improving the concentricity of inner and outer circles in rotor processing. Background technique [0002] For the design of the rotor with processing capacity, the common processing technology in the industry is to process the inner hole of the rotor first, and then process the outer circle of the rotor with the inner hole positioning. The advanced rotor can ensure the concentricity of the inner hole and the outer circle. [0003] The current technology is difficult to ensure the concentricity of the inner hole and the outer circle for the machining of the rotor whose counterbore depth is greater than one-third of the rotor stack thickness, so a processing technology that can improve the concentricity of the inner and outer circles of the rotor machining is required. [0004] However, the existing processing technology has ...
