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 supportingly with working machine, is used to accomplish each item work.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 the 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 the axial thrust of electric machine main shaft to the 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 reference.The drawback of this processing technology is; After the motor general assembly is accomplished; Because 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 the seam machine-shaping.Like this, in the process of motor and working machine connection operation, bring a series of trouble, the one, the end cap flange is for the circular runout of electric machine main shaft and the reactive loss and the waste of electric energy of axial runout formation electric machine main shaft rotary power; The 2nd, cause electric machine main shaft and working machine side power transmission member premature wear and flexural fatigue to be damaged easily, or/and the damage of end cap flange bolt, the equipment integral failure rate increase the 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 influences 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 motor quality and equipment operation motor production technology stably.
Realize that the technical scheme that the object of the invention is taked is: a kind of motor production technology, comprise processing of member blank or blanking, also include following processing step:
A. member processing: get the end cap flange blank, with the rough turn moulding of its end face and seam position, the finish turning moulding of inner circular part position, it is subsequent use to process end cap flange light base, and presses common process with the whole machine-shapings of other member of motor;
B. motor semi-finished product assembling: by packaging technology with all members of motor of machine-shaping comprise end cap flange light base all assembling become the motor semi-finished product for standby;
C. end cap end face of flange and seam processing: with said 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. processing of end cap flange connecting hole and the assembling of motor finished product: the motor semi-finished product that will accomplish end cap end face of flange and seam place 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.
Among the said step C, the processing of end cap end face of flange and seam is positioning reference with the electric machine main shaft.
The production technology of motor of the present invention through the adjustment of technological process, can be eliminated the accumulated error of relative electric machine main shaft circular runout of end cap end face of flange and seam and axial runout easily; Thereby guarantee the precision that is connected of motor and working machine reliably, realize the even running of equipment, and the consumption that can save electric energy; Reduce the equipment operation fault; Prolong service life of equipment, this process is simple, and effect is remarkable.
Description of drawings
Fig. 1 is the structural representation of motor among the present invention.
Embodiment
Referring to Fig. 1, be the structural representation of motor among the present invention, label is respectively among the figure: 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; Be after blank or raw material blanking operation are forged in the casting of accomplishing respective members; Press earlier each member except that end cap flange 1 the whole machine-shapings of common process with motor, and with the 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; Process the light base of end cap flange 1, the light base that all members of motor of machine-shaping is comprised end cap flange 1 by packaging technology more all assembling becomes the motor semi-finished product.Then; Said motor semi-finished product clamping on the machined into station, is carried out the finish turning moulding of the end face of flange 1-1 and the seam 1-2 of end cap flange 1, in the process of finish turning moulding; With electric machine main shaft 4 is positioning reference; Be about to electric machine casing 2 cylindricals and be installed on the 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 the end face of flange 1-1 and the seam 1-2 of end cap flange 1.At last, the motor semi-finished product of accomplishing end cap flange 1 upper flange end face 1-1 and seam 1-2 finish turning are placed the processing stations of drilling machine, carry out the machine-shaping of connecting hole 1-3 on the end cap flange 1, promptly become the motor finished product.This production technology can be eliminated the end face of flange 1-1 of end cap flange 1 and the accumulated error after the seam 1-2 assembling effectively; End face of flange 1-1 and the seam 1-2 that guarantees assembling rear end cap flange 1 reliably with respect to electric machine main shaft 4 radially, the axial runout error in allowed band, and then assurance equipment moves stably.
