A manufacturing method of a stator frame

Abstract

The invention relates to a stator base processing and manufacturing method, comprising the steps of: (1) inspecting the size allowance of a stator base blank piece; (2) using a carrying pole beam to lift the stator base blank piece to a vertical lathe workbench; (3) in a clamping process, welding three layers of pressing plates on a cylinder wall in a step shape, wherein each layer is provided with four pieces in a crossing mode to compress the stator base blank piece; and first performing rough turning, then loosening the pressing plates, and lightly pressing the pressing plates to perform finish turning on the size at each position; (4) measuring on the vertical lathe workbench to record all sizes to be used as a final installation size recording of a stator base; (5) using the carrying pole beam to lift the stator base after finish turning, and installing the stator base on a turning tool after assembling with a stator support; (6) turning the stator base, driving a turning mould to be lifted to a boring mill workbench, and using a drill lifting tool to lift a drill to distribute drilling holes after assembling with a sealing cover plate; and (7) turning trunnion apertures on two sides of a boring mill; and performing circularity regulation when deformation of the stator base is greater. The stator base processing and manufacturing method can effectively solve the problems of deformation and poor dimension.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a manufacturing method for a stator frame. Background technique [0002] Wind power is a renewable and clean energy. Wind power generation is an important form of wind energy utilization.

AI Technical Summary

Problems solved by technology

The outer dimension of the stator base is 5.6 meters and the wall thickness is 10mm. It is a large thin-walled part, which is easy to deform after hoisting. At the same time, the strict dimensional tolerance requirements are difficult to control during the processing process, and the production is difficult.
