Abstract
The invention relates to a processing technology of a solid rotor permanent magnet motor rotor. The solid rotor permanent magnet motor rotor is composed of a solid rotor body and a magnetic isolation system; and the magnetic isolation system is composed of a magnetic pole support ring. The processing technology of the invention comprises the following steps: the solid rotor body and the magnetic pole support ring are processed in turn; a technology groove is planed for the magnetic pole support ring before the solid rotor body and the magnetic pole support ring are welded; finish turning is carried out after the solid rotor body and the magnetic pole support ring are welded, small grooves are processed and a magnetic steel straight groove is rough machined by using a hacksaw machine; and then finish milling is carried out for the magnetic steel straight groove and a dovetail groove. By using the invention, the production time and cost are saved, the work efficiency and the benefit of an enterprise are improved, and the loss amount of tools is greatly reduced.
Description
Technical field
The present invention relates to a kind of fine-processing technique, relate in particular to a kind of processing technology of solid rotor permanent magnet motor rotor.
Background technology
Magneto uses more and more widely because its power savings is outstanding.The rotor of solid-rotor permanent-magnet motor is formed by the ferromagnetic solid rotor body with at a distance from magnetic system, and its structure is divided into rotor block and two parts of magnetic pole support ring.The conventional machining process of permanent magnet machine rotor is: 1) to the processing of solid rotor body: with the blanking of mild steel blank, blank is forged, deliver to the lathe Vehicle Processing with forging good solid rotor chaeta base.2) to the processing of magnetic pole support ring: with the blanking of stainless steel blank, blank is forged, deliver to the lathe Vehicle Processing with forging good magnetic pole support ring blank.3) to the processing of rotor: with 1) the solid rotor body and 2 that obtains of procedure) the magnetic pole support ring welding that obtains of procedure; After welding is good; The finish turning rotor is to specified size; Begin repeatedly feed then and mill sulculus, magnet steel straight trough and dovetail groove, meet dimensional requirement, deliver to the processing of slotting machine keyseat at last and obtain finished product up to sulculus, magnet steel straight trough and dovetail groove.This kind method is directly milled sulculus, magnet steel straight trough and dovetail groove with milling cutter, divide multitool to carry out, and the needed operating time of milling cutter is longer; And chip removal is not smooth in working angles, damages cutter easily, need change cutter again; Not only the cutter waste is big; Also wasted the production time, increased production cost, operating efficiency is very low.
Summary of the invention
The present invention before solid rotor body and the welding of magnetic pole support ring, with magnetic pole support ring digs technology groove earlier in order to overcome the above problems the processing technology that a kind of solid rotor permanent magnet motor rotor is provided; After welding and finish turning processing, process sulculus, roughing magnet steel straight trough with sawing machine again, then magnet steel straight trough and dovetail groove are carried out finish-milling; Practiced thrift a large amount of production times, improved operating efficiency, the waste of cutter reduces significantly simultaneously; Practice thrift production cost, improved the benefit of enterprise.
Technical scheme of the present invention is: the processing technology of solid rotor permanent magnet motor rotor, and described permanent magnet machine rotor is formed by the solid rotor body with at a distance from magnetic system, and described separated magnetic system is made up of the magnetic pole support ring, processes by following concrete mode:
1) to the processing of solid rotor body: with the blanking of mild steel blank, blank is forged, deliver to the lathe Vehicle Processing with forging good solid rotor chaeta base.
2) to the processing of magnetic pole support ring: with the blanking of stainless steel blank, blank is forged, deliver to the lathe Vehicle Processing, deliver to planer plane technology groove after car is good with forging good magnetic pole support ring blank.
3) to the processing of rotor: with 1) the solid rotor body and 2 that obtains of procedure) the magnetic pole support ring welding that obtains of procedure; After welding was good, the finish turning rotor adopted saw processing to leave some straight troughs to the magnet steel groove on the magnetic solid rotor body of rotor to specified size then; Respectively stay certain surplus on the groove both sides; At sulculus of per two adjacent straight trough middle position processing, then epitrochanterian magnet steel straight trough is carried out finish-milling simultaneously, make being of the required size of magnet steel straight trough; Simultaneously above each magnet steel straight trough, mill dovetail groove and make it meet dimensional requirement, at last the rotor that obtains is carried out line cutting keyway and obtain end product.
Advantage of the present invention is: before solid rotor body and the welding of magnetic pole support ring, earlier the magnetic pole support ring is dug technology groove, behind welding and the finish turning; With sawing machine process sulculus, roughing goes out the magnet steel straight trough, and then magnet steel straight trough and dovetail groove is carried out finish-milling, has practiced thrift a large amount of production times; Improved operating efficiency; The waste of cutter reduces significantly simultaneously, has practiced thrift production cost, has improved the benefit of enterprise.
Embodiment
The processing technology of solid rotor permanent magnet motor rotor, described permanent magnet machine rotor is formed by the solid rotor body with at a distance from magnetic system, and this is made up of the magnetic pole support ring at a distance from magnetic system, and concrete processing technology is following:
1) to the processing of solid rotor body: with the blanking of mild steel blank, blank is forged, deliver to the lathe Vehicle Processing with forging good solid rotor chaeta base.
2) to the processing of magnetic pole support ring: with the blanking of stainless steel blank, blank is forged, deliver to the lathe Vehicle Processing, deliver to planer plane technology groove after car is good with forging good magnetic pole support ring blank.
3) to the processing of rotor: with 1) the solid rotor body and 2 that obtains of procedure) magnetic pole support ring welding that procedure obtains, after welding was good, the finish turning rotor was to specified size; Adopt saw processing to leave some magnet steel straight troughs to the magnet steel groove on the solid rotor body of rotor then; Respectively stay certain surplus on the groove both sides, saw out a sulculus at per two adjacent magnet steel straight trough middle positions simultaneously, then epitrochanterian magnet steel straight trough is carried out finish-milling; Make being of the required size of magnet steel straight trough; Simultaneously end mill dovetail groove and make it meet dimensional requirement on each magnet steel straight trough only needs a feed, has shortened process time greatly.The saw of one 8 utmost point motor rotor magnetic steel straight trough, sulculus and dovetail groove and the time of milling processing are 9.3 hours; Produce the original processing technology of milling of time ratio of every rotor and save 150.7 hours; Processing charges is 230 yuan, produces every present technology of rotor and saves 2170 yuan than original technology, and the cutter waste reduces significantly; One slitting milling cutter can be processed 40-50 platform rotor, at last the rotor that obtains is carried out line cutting keyway and obtains end product.
