Example Embodiment

[0015] The method for processing a small and medium motor frame of the present invention includes the following steps:

[0016] The first step is to cast the workpiece, and use the casting method to cast the workpiece blank;

[0017] The second step is heat treatment, using annealing process to anneal the blank. When the workpiece is annealed, enter the furnace when the furnace temperature is below 300℃. After the workpiece is put into the furnace, close the furnace cavity and control the heating rate within the range of 100-150℃ / h ,, When the furnace temperature rises to 550℃~650℃, the steel base shall be kept in this temperature range for 1~2 h. When the furnace temperature rises to 500℃~550℃, the cast iron base shall be kept for 4h within this temperature range. ~6h, after the heat preservation time, the workpiece will be cooled with the furnace, and the temperature in the furnace will not drop more than 100℃ / h. If the temperature drops too fast, it should be heated appropri...

Abstract

The invention relates to the field of machining, in particular to a method for a small-and-medium-size motor seat. The method includes the following steps of casting a workpiece; conducting heat treatment; conducting rough turning, wherein the non-wire-outlet end of the motor seat is clamped on a vertical lathe; conducting rough turning, wherein one-time turning stop opening seat mold positioning and clamping are conducted, and a stop opening, the end face and an iron core baffle of the non-wire-outlet end are roughly turned, the finish turning allowance of the stop opening and the iron core baffle is reserved to range from 2 mm to 3 mm, and the finish turning allowance of the end face is reserved to range from 1.5 mm to 2 mm; conducting finish turning on the iron core baffle, wherein tail end stop opening seat mold positioning and clamping are conducted, finish turning is conducted on the iron core baffle till the iron core baffle meets the drawing requirement to be matched with a stator iron core, and the mold matching clearance is smaller than 0.1 mm; pressing the stator iron core into the motor seat; conducting rough turning on the stop opening, wherein the internal diameter of the stator iron core serves as a reference, and upper and lower meter running alignment is conducted; conducting finish turning on the stop opening, wherein four-time turning stop opening seat mold positioning and clamping are conducted, meter running alignment is conducted on the iron core jump which is controlled within 0.06 mm, finish turning is conducted on a stop opening and the end face of the extension end, and the total length is controlled to meet the drawing requirement; conducting detection. The machining process is simple, the workpiece machining quality and dimensional accuracy can be guaranteed, production efficiency is improved, and production cost is reduced.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a processing method for small and medium-sized motor frames. Background technique [0002] During the normal production and working process of the motor, the precision of each component and instrument is very high. If there is a problem with a certain component or link, it will cause unimaginable consequences to the motor equipment. At both ends of the motor base, there are two devices for the axis, the inner circle and the notch. When the motor is working, the rotation of the axis drives the center of the end face, and the jump has a great impact on the overall performance of the motor. Therefore, in order to find a breakthrough in various precision components and increase the working efficiency of the motor, it is necessary to carry out fine processing on the motor frame, so as to reduce the errors generated in the core manufacturing process. Therefore, it is very importan...
