Abstract
The invention discloses a motor production technology. The technology is mainly characterized in that an end surface and a seam allowance part of an end cover flange are formed by rough turning, and other parts are formed by finish turning; and after the end surface and the seam allowance part are completely assembled with other components of the motor, the processing of the end surface and the seam allowance of the end cover flange and the formation of a connection hole are performed. Through the production technology, the accumulated error of radial runout and axial runout of the end cover and the seam allowance of the end cover flange relative to a main shaft of the motor can be easily eliminated so that the connection accuracy between an electric motor and a working machine can be reliably guaranteed, stable operation of equipment is realized, power consumption is reduced, operation failures of equipment is reduced, and the service life of equipment is prolonged; and the technology is simple and easy to implement and has obvious effects.
Description
Technical field
The invention belongs to the motor production technical field, particularly a kind of motor production technology.
Background technology
Motor is to use at present the most general power-equipment, is connected with working machine supporting, for completing work in every.Motor is generally assembled by housing, stator, rotor, electric machine main shaft, end cap flange and afterbody end cap.And be arranged on the end cap flange of housing shaft extension end, be used for the bearings of electric machine main shaft and the connection of motor and working machine.Particularly in electric machine main shaft and the direct rigidly connected equipment of working machine side power transmission member, circular runout and axial runout error with respect to electric machine main shaft after end cap end face of flange and seam machine-shaping there is extremely strict requirement, to guarantee the concentric of electric machine main shaft and working machine side power transmission member, reduce electric machine main shaft to the axial thrust of working machine side power transmission member.And at present to the processing method of end cap end face of flange and seam, normally to the independent machine-shaping of end cap flange, and with bearing mounting hole as the processing positioning datum.The drawback of this processing technology is, after the motor general assembly is completed, due to the accumulated error that the inside and outside circle of electric machine main shaft cylindrical, bearing and end cap flange bearing installing hole etc. produce, be easy to cause that circular runout and the axial runout error with respect to electric machine main shaft exceeds design standard after end cap end face of flange and seam machine-shaping.Like this, bring a series of trouble in the process of motor and working machine connection operation, the one, the end cap flange forms the reactive loss of electric machine main shaft rotary power and the waste of electric energy for circular runout and the axial runout of electric machine main shaft; The 2nd, easily cause electric machine main shaft and working machine side power transmission member premature wear and flexural fatigue to be damaged, or/and the damage of end cap flange bolt, the Whole Equipment failure rate increase reduction with operating efficiency; The 3rd, electric machine main shaft produces axial runout because of radial force with respect to motor stator, and the magnetic gap pulsating nature changes, and affects the stationarity of motor rotation, and then brings series of malpractice; The 4th, cause the machining accuracy grade of electric machine main shaft and end cap flange high, difficulty of processing strengthens, and manufacturing cost is high.
Summary of the invention
The purpose of this invention is to provide a kind of defective that can overcome prior art, reduce the difficulty of processing of each member of motor, effectively guarantee the motor production technology that motor quality and equipment operate steadily.
Realize that the technical scheme that purpose of the present invention is taked is: a kind of motor production technology, comprise the processing of member blank or blanking, also include following processing step:
A. member processing: get the end cap flange blank, with its end face and the rough turn moulding in seam position, inner circle position finish turning moulding is made end cap flange light base standby, and routinely technique with the whole machine-shapings of other member of motor;
B. motor semi-finished product assembling: all members of motor of machine-shaping are comprised that end cap flange light base all is assembled into the motor semi-finished product for standby by packaging technology;
C. end cap end face of flange and seam processing: with described motor semi-finished product clamping on the machined into station, with end cap end face of flange and the moulding of seam finish turning;
D. the processing of end cap flange connecting hole and motor product assembling: the motor semi-finished product that will complete end cap end face of flange and seam are placed in the drilling machine processing stations, carry out the machine-shaping of end cap flange connecting hole, load onto motor afterbody end cap after taking off and get final product.
In described step C, the processing of end cap end face of flange and seam is take electric machine main shaft as positioning datum.
The production technology of motor of the present invention, adjustment by technological process, can eliminate easily the accumulated error of the relative electric machine main shaft circular runout of end cap end face of flange and seam and axial runout, thereby guarantee reliably the precision that is connected of motor and working machine, realize the even running of equipment, and can save the consumption of electric energy, reduce equipment operation failure, extension device useful life, this process is simple, and effect is remarkable.
Description of drawings
Fig. 1 is the structural representation of motor in the present invention.
Embodiment
Referring to Fig. 1, be the structural representation of motor in the present invention, number in the figure is respectively: end cap flange 1, electric machine casing 2, afterbody end cap 3, end face of flange 1-1, seam 1-2, electric machine main shaft 5 and connecting hole 1-3.The production technology of motor of the present invention, after blank or raw material blanking procedure are forged in the casting of completing respective members, first technique routinely is with each member whole machine-shapings except end cap flange 1 of motor, and with end face of flange 1-1 and the rough turn moulding in seam 1-2 position of end cap flange 1 blank, all the other position finish turning moulding, make the light base of end cap flange 1, then by packaging technology, all members of motor of machine-shaping are comprised that the light base of end cap flange 1 all is assembled into the motor semi-finished product.Then, with described motor semi-finished product clamping on the machined into station, carry out the finish turning moulding of end face of flange 1-1 and the seam 1-2 of end cap flange 1, in the process of finish turning moulding, take electric machine main shaft 4 as positioning datum, be about to electric machine casing 2 cylindricals and be installed on lathe chuck, the shaft extension end holds out against with the top centre bore with electric machine main shaft 4 of lathe tail, carries out the finish turning moulding of end face of flange 1-1 and the seam 1-2 of end cap flange 1.At last, the motor semi-finished product of completing end cap flange 1 upper flange end face 1-1 and seam 1-2 finish turning are placed in the processing stations of drilling machine, carry out the machine-shaping of connecting hole 1-3 on end cap flange 1, namely become motor product.This production technology can be eliminated the end face of flange 1-1 of end cap flange 1 and the accumulated error after seam 1-2 assembling effectively, guarantee reliably the end face of flange 1-1 of assembling rear end cap flange 1 and seam 1-2 with respect to electric machine main shaft 4 radially, the axial runout error in allowed band, and then assurance equipment moves stably.
