Description
Technical field
The present invention relates to the motor process technology, particularly relate to a kind of technology for frock clamp and using method thereof under a cutter of processing motor case.
Background technology
Existing motor mainly is comprised of critical components such as casing, end cap, footing, stator, rotor, bearings.wherein stator is fixed on casing, the inner circle of its cylindrical and casing is friction tight, footing (installing for the client) is fixed on bottom of shell, be used for support machine casing, bearing holder (housing, cover) is located on the axle journal of two ends of rotor, a main support rotor and assurance rotor can along the circumferential direction freely rotate, end cap is used for spring bearing, and its seam matches with the casing seam, also supporting rotor when therefore casing is fixed wtih stator, and has certain gap between the cylindrical of the inner circle of stator and rotor, the concentricity of the two cooperation in the ideal situation, monolateral gap is in the 0.25-0.8 left and right.
as Fig. 2, shown in Figure 3, because the existing clamping end of frock clamp for the processing motor case all is plane, therefore requiring clamping of workpiece to hold end face must be also the plane, make present motor case processing all adopt tune Vehicle Processing technique, namely first with the inner circle (referring to Fig. 2) of the scroll chuck 17 swelling casings 13 on lathe spindle, casing 13 is fixed on lathe, then turning casing 13 is towards seam and this end seam end face of lathe tool one end, after turning is complete, casing 13 is unloaded from lathe, and then will again load onto lathe after casing 13 tune commutations, and utilize four lugs 14 on casing 13 that casing 13 is fixed on (referring to Fig. 3) on lathe tool fixture 11, casing 13 not the end crossed of car towards lathe tool, the seam of the end crossed of car is towards the seam of lathe tool fixture 11, the seam end face of its seam end face and lathe tool fixture 11 is fitted, and then turning casing 13 not seam and this end seam end face of the end crossed of car, and the inner circle of turning casing 13.
Due to traditional tune Vehicle Processing technique due to twice clamping casing of needs, therefore for the second time during the clamping casing, can produce following several situations: 1) as shown in Figure 4, if the seam of lathe tool fixture 21 have wearing and tearing or casing 23 seams too large, in the time of can causing secondary clamping casing the seam of an end of turning coordinate partially pine with the seam of lathe tool fixture 21, after making the whole completion of processing of casing 23, its two ends seam end face is parallel, and two ends seam center line departs from; 2) as shown in Figure 5, if the casing 33 seam end face of an end of turning has foreign matter to exist, or the seam end face of lathe tool fixture 31 has foreign matter to exist, or both all have foreign matter to exist, or four lugs on casing 33 have not fastening individually, after can causing the whole completion of processing of casing 33, its two ends seam end face is uneven; When 3) above-mentioned two kinds of situations existed simultaneously, after can causing the whole completion of processing of casing, its two ends seam end face was uneven, and its two ends seam center line also departs from.This shows, the machining accuracy of traditional tune Vehicle Processing technique is lower, easily cause the non-uniform air-gap between rotor after the motor case assembling that processes, serious meeting causes rotor to produce friction, make the bearing enclose raceway send mechanicalness noise because being on uneven track, and affect the life-span of bearing.
Summary of the invention
For the defective that exists in above-mentioned prior art, technical problem to be solved by this invention is to provide frock clamp and using method thereof under the high cutter that is used for the processing motor case of a kind of machining accuracy.
in order to solve the problems of the technologies described above, provided by the present invention a kind of for frock clamp under a cutter of processing motor case, comprise jig main body and four hasps, described jig main body is fixed on lathe, jig main body towards an end of lathe tool direction for clamping end, the two ends of motor case to be processed are respectively the first processing end and the second processing end, outer peripheral face axial symmetry of its first processing end be provided with four radially outward protrude take part, it is characterized in that: the end end face axial symmetry that clamps of described jig main body is provided with four towards lathe tool direction protrusion and the identical projection of geomery,
Be equipped with the flange that protrudes towards the central axial direction of jig main body on each projection, each projection is equipped with the screw for fixed agraffe on the end face of lathe tool one side;
Spacing between the projection at each projection and its diagonal angle, process the external diameter of the seam to be processed of end greater than motor case first to be processed, and less than taking in part of motor case to be processed the first processing end outer peripheral face, take the spacing between the outer end of part two of diagonal angle;
The end of the flange on each projection and jig main body clamp the spacing of end between end face greater than the width of lathe tool.
Using method for frock clamp under a cutter of processing motor case provided by the present invention is characterized in that, concrete steps are as follows:
1) with the first processing end of motor case to be processed towards jig main body, and make four of the first processing end outer peripheral face take part to prop up respectively four flanges on projection, make the seam to be processed of the first processing end between the flange of four projections;
2) fasten respectively four of motor case to be processed the first processing end with four hasps and take part, and utilize bolt that four hasps are separately fixed on four projections;
3) distinguish two ends seam and the seam end face of turning motor case to be processed with lathe tool, and the inner circle of turning motor case to be processed;
4) first unscrew the bolt of fixing four hasps after the turning completion four hasps are unclamped, then take off the motor case of completion of processing.
provided by the invention for frock clamp and using method thereof under a cutter of processing motor case, because the end end face that clamps of jig main body is provided with four projections that protrude towards the lathe tool direction, and be equipped with the flange that protrudes towards the jig main body central axial direction on each projection, the end of each flange and jig main body clamp the spacing of end between end face greater than the width of lathe tool, make motor case to be processed leave towards seam end face to be processed and the clamping between the end end face of jig main body of jig main body one end the space of stretching into for lathe tool, therefore only need clamped one time just all can be wanted to unload workpiece after the whole completion of processing of Working position again, thereby effectively avoided departing from because secondary clamping causes after the whole completion of processing of casing the not parallel and two ends seam center line of two ends seam end face, have the high characteristics of machining accuracy.
