Abstract

The invention discloses a processing technology of a motor base. The processing technology comprises the following steps of: processing a locating end face on three ribs at an end K of the base, and processing a section of boss on the periphery of the base, thereby forming a location datum of the base by the locating end face and the boss; then, fixing the base on a lathe by a claw-type technical flange through the location datum, finishing all the inner circles, end faces, chamfers and the like of the base within once finish turning, realizing the needed final size of the base, and finishing the processing. The processing technology of the motor base in the scheme of the invention is simple to operate, and greatly improves the coaxiality of the base, so that the uniformity of air gaps of the motor is ensured, and vibration and noise generated in working process of the motor are reduced; and simultaneously, the rejection rate in base processing is reduced, and work efficiency and production efficiency both are improved.

Description

A kind of processing technology of electric machine stand
Technical field
The present invention relates to a kind of processing technology of machine components, especially a kind of processing technology of electric machine stand belongs to the electric machine stand processing technique field.
Background technology
In processing during electric machine stand, for guarantee motor gas-gap evenly, the seam at electric machine stand two ends and the axiality of iron core retaining are had strict requirement, but because the self structure of electric machine stand, need repeatedly reverse end for end man-hour to folder, location repeatedly adding.Generally all process through following step:
Figure 790375DEST_PATH_IMAGE002
holds with the K that scroll chuck grasps support, the end face and the seam of rough turn N end;
Figure 313761DEST_PATH_IMAGE004
is benchmark with the seam of support N end, and machining tool N holds on the big muscle three the fixedly screwed holes (by drill jig) used of end cap;
Figure 2011104235731100002DEST_PATH_IMAGE006
is benchmark with the end face and the seam of support N end; Support is fixed on the process flange (claiming the seam tire again); The end face of rough turn K end, seam, transition retaining and iron core retaining; Do not unload workpiece, then end face and transition retaining, seam to end value and the chamfering of finish turning K end;
Figure 2011104235731100002DEST_PATH_IMAGE008
is benchmark with the seam of support K end, and processing K holds on the big muscle three the fixedly screwed holes (by drill jig) used of end cap;
Figure 2011104235731100002DEST_PATH_IMAGE010
is benchmark with support K end end face and seam; Support is fixed on another process flange; Finish turning N end transition retaining, seam and iron core block to end value; And the end face of finish turning N end to make support length be end value and chamfering, support completion of processing on lathe so far.
In above-mentioned support manufacturing procedure, the support N of decision support axiality, K two ends and iron core retaining are respectively in different clamping operations, to accomplish, and their machining benchmark do not overlap yet, so the axiality of support just can only rely on frock to guarantee.And convenient for installing and locating, all matched in clearance between the seam of support and the process flange, exist certain fit tolerance between the two, this just can influence the axiality of support inevitably.Especially under the situation of process flange heavy wear, influence is just bigger.In addition; In step
Figure 117506DEST_PATH_IMAGE006
; Rough turn back also can influence machining accuracy at once with regard to finish turning.This is that the workpiece epidermis is harder because the chipping allowance when rough turn is big, causes that support heating, distortion are serious, and the seam that goes out of finish turning certainly exists very big error in this case, and follow-up processing with this seam as benchmark, must influence machining accuracy.These errors not only can cause the scrappage of support processing, waste a lot of processing costs; Simultaneously,, also be easy to influence the operate as normal of motor, produce vibration and noise, not only environment has been caused pollution, also reduced the life-span of motor for the motor that axiality is had relatively high expectations.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of can be in clamping, the processing technology of the accurately machined electric machine stands in position such as circle, end face, two ends seam in accomplishing.
Technical solution of the present invention is achieved in that a kind of processing technology of electric machine stand, may further comprise the steps:
