Description
Technical field
The present invention relates to electric machine field, be specifically related to a kind of precise machining process of motor shaft.
Background technology
Motor can run in use and must obtain larger output torque on axle, and the axle external space is subject to strict restriction, is difficult to arrange the arm of force in slender space, reduce mechanical efficiency, meanwhile, motor shaft is because lead-in wire needs perforation, bearing capacity is more weak, reduces mechanical strength.In addition, in process of production, owing to needing to adopt exterior mechanical to carry out the operation of milling, cutting, perforate and so on motor shaft, easily the intensity of motor shaft is impacted, thus destroy the internal structure of motor shaft, shorten the service life of motor shaft.In process, often run into various unmanageable position in addition, thus reduce working (machining) efficiency, waste a large amount of manpower and materials, working effect is poor.
Summary of the invention
The object of the present invention is to provide one to contribute to improving working (machining) efficiency, reduce difficulty of processing, increase economic efficiency, and the precise machining process of motor shaft easy and safe to operate.
Technical scheme of the present invention is, a kind of precise machining process of motor shaft, comprises the steps:
1) milling roughing: first raw material is excised a large amount of clouts by milling, carries out being processed into blank in the mode being divided into different amount, and leaves a small amount of surplus;
2) heat treatment: afterwards blank is put into stove, slowly arrive less than 450 DEG C after intensification a period of time, afterwards with the programming rate of 120 DEG C per hour, be heated to about 700 DEG C, and keep in the inherent heating process of stove, the temperature difference in each district is not more than 30 DEG C, be incubated in stove, temperature retention time 4-6 hour, finally in the stove of closing, with the cooling rate of 50 DEG C/h, be cooled to 200 DEG C;
3) form grinding: be interposed on clamp by blank blank, is carried out grinding by the fixing or continuous position that changes thus is obtained required form;
4) linear cutter: be placed on the enterprising line cutting processing of WEDM afterwards, cut out the motor shaft of blank required form and size by WEDM continuously pulsed discharge;
5) moulding: being placed on afterwards on plain-milling machine by milling cutter rotary motion is main motion, motor shaft (with) movement of milling cutter is feed motion, carry out being processed into required shape and size at blank surface;
6) numerical control workshop: be placed on afterwards on numerically controlled lathe again and carry out turnery processing, improves the shape and size size with required motor axle further;
7) NC milling: carry out last processing to motor shaft finally by NC milling, completes further by the manufacturing procedure that common Milling Process cannot be carried out, and makes motor shaft complete all shape requirements and size;
8) Electric Discharge Machining: etched on motor shaft surface by pulsed discharge, the place of milling cannot complete last processing by some engine lathes and milling machine;
9) dimensional gaughing: carry out dimensional measurement to the motor shaft machined, can store rear delivery when all data all reach necessary requirement and dispatch from the factory.
In a preferred embodiment of the present invention, form grinding after described Linear cut process, is also had to process blank further.
In a preferred embodiment of the present invention, in described hot procedure, be heated to 450 DEG C of needs 3 hours.
Of the present invention is a kind of precise machining process of motor shaft, and the present invention contributes to improving working (machining) efficiency, reduces difficulty of processing, increases economic efficiency, and easy and safe to operate.
Detailed description of the invention
