Method for processing stator

Abstract

The invention discloses a stator processing method. The method comprises the following steps: a) a first axis body is clamped by a first processing mould, and a first screw thread bottom hole is processed on the end surface of a second axis body; b) the second axis body is clamped by a second processing mould, a first positioning pin on the second processing mould is used for positioning, and a second screw thread bottom hole is processed on the end surface of the first axis body; and c) the first axis body is clamped by a third processing mould, a second positioning pin of the third processing mould is used for positioning, a third hole is processed on the peripheral wall of the first axis body, and a trough is processed on the end surface of the second axis body. The three groups of processing moulds are utilized to clamp processed stators, and the positioning pins on the processing moulds are used for positioning the stators to simplify the operating process of processing the stators with high precision; moreover, hole positions needing to be processed on the stators are made more standard, and contraposition between every two hole positions is more accurate. The method has theadvantages of lightening labor intensity and improving the processing efficiency of the stators.

Description

【Technical field】 [0001] The invention relates to the field of mechanical processing, in particular to a stator processing method. 【Background technique】 [0002] During the early processing of the stator and stator sleeve of the workpiece, after the shape is completed in the CNC lathe process, the CNC uses the indexing turntable to clamp and mill the 4-M2 threaded hole and the 2.5 wide groove in the vertical direction. In the milling process, the rotary table of the dividing head is used to clamp the 2-M2 thread on the back of the milling drill. And the φ2(+0.1 / 0.05) hole on the shaft. This is prone to the following disadvantages: [0003] First, the clamping force of the processing makes the outer surface of the workpiece pinched and deformed, which is easy to produce waste products; [0004] Second, the position requirements of the 4-M2 thread, the 2-M2 thread on the back and the φ2 (+0.1 / +0.05) hole on the shaft cannot be guaranteed; [0005] Third, since the materia...

AI Technical Summary

Problems solved by technology

[0003] First, the clamping force of the processing makes the outer surface of the workpiece pinched and deformed, which is easy to produce waste products;

[0004] Second, the position requirements of the 4-M2 thread, the 2-M2 thread on the back and the φ2 (+0.1 / +0.05) hole on the shaft cannot be guaranteed;

Because it is automatic feeding during drilling, it is difficult to cut and the drill bit is easy to break

[0006] Fourth, it is inconvenient to operate, long processing time, low efficiency, and easy to cause high labor intensity for operators.
