Description
Technical field
The present invention relates to the motor process technology, particularly relate to the technology of frock clamp under a kind of cutter that is used to process motor case and using method thereof.
Background technology
Prior motor mainly is made up of critical components such as casing, end cap, footing, stator, rotor, bearings.Wherein stator is fixed on the casing, the interior circle of its cylindrical and casing is friction tight, footing (usefulness being installed 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 being fixed stator, and have certain clearance between the cylindrical of the interior circle of stator and rotor, and the concentricity of the two cooperation is under perfect condition, and monolateral gap is about 0.25-0.8.
As Fig. 2, shown in Figure 3, because the existing clamping end that is used to process the frock clamp of motor case all is plane, therefore requiring clamping of workpiece to hold end face also must be the plane, make present motor case processing all adopt tune Vehicle Processing technology, promptly first interior circle (referring to Fig. 2) with the 17 swelling casings 13 of the scroll chuck on the lathe spindle, casing 13 is fixed on the lathe, turning casing 13 is towards seam and this end seam end face of lathe tool one end then, after turning finishes casing 13 is unloaded from lathe, and then will load onto lathe again after the casing 13 tune commutations, and utilize four lugs 14 on the casing 13 that casing 13 is fixed on (referring to Fig. 3) on the lathe frock clamp 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 frock clamp 11, and the seam end face of its seam end face and lathe frock clamp 11 is fitted; And then turning casing 13 not seam and this end seam end face of the end crossed of car, and the interior circle of turning casing 13.
Because traditional tune Vehicle Processing technology is owing to need twice clamping casing, 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 frock clamp 21 have wearing and tearing or casing 23 seams too big, in the time of can causing the secondary clamping casing the seam of an end of turning cooperate partially pine with the seam of lathe frock clamp 21, make that its two ends seam end face is parallel after the casing 23 whole completion of processing, 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 frock clamp 31 has foreign matter to exist, or both all have foreign matter to exist, or four lugs on the casing 33 have not fastening individually, after can causing casing 33 whole completion of processing, its two ends seam end face is uneven; When 3) above-mentioned two kinds of situations exist simultaneously, can cause the whole completion of processing of casing after, its two ends seam end face is uneven, and its two ends seam center line also departs from.This shows, the machining accuracy of traditional tune Vehicle Processing technology is lower, cause the air gap between rotor inhomogeneous easily after the motor case assembling that processes, serious meeting causes rotor to produce friction, make the bearing enclose raceway send mechanicalness noise, and influence the life-span of bearing because of being on the uneven track.
Summary of the invention
At the defective that exists in the above-mentioned prior art, technical problem to be solved by this invention provides high being used to of a kind of machining accuracy and processes frock clamp and using method thereof under the cutter of motor case.
In order to solve the problems of the technologies described above, frock clamp under a kind of cutter that is used to process motor case provided by the present invention, comprise jig main body and four hasps, described jig main body is fixed on the 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 and protrudes and the identical projection of geomery towards the lathe tool direction;
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 that is used for fixing hasp 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, take the spacing between the outer end of part two of diagonal angle less than taking in the part of the motor case to be processed first processing end outer peripheral face;
The end of the flange on each projection and jig main body clamp the width of the spacing of end between the end face greater than lathe tool.
The using method of frock clamp under the cutter that is used to process 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 four flanges on the projection respectively, the seam to be processed that makes the first processing end is between the flange of four projections;
2) fasten four of the motor case to be processed first processing end respectively with four hasps and take part, and utilize bolt that four hasps are separately fixed on four projections;
3) with lathe tool respectively the two ends seam and the seam end face of turning motor case to be processed, and the interior circle of turning motor case to be processed;
4) unscrew the bolt of fixing four hasps earlier after the turning completion four hasps are unclamped, take off the motor case of completion of processing then.
Frock clamp and using method thereof under the cutter that is used to process motor case provided by the invention, because the end end face that clamps of jig main body is provided with four projections that protrude towards the lathe tool direction, and on each projection, be equipped with the flange that protrudes towards the jig main body central axial direction, the end of each flange and jig main body clamp the width of the spacing of end between the end face greater than lathe tool, make motor case to be processed leave the space that the cutter of buying car in installments stretches into towards the seam end face to be processed and the clamping between the end end face of jig main body of jig main body one end, therefore only need a clamping just all can be wanted to unload workpiece again after the whole completion of processing of Working position, thereby effectively avoided departing from, had the high characteristics of machining accuracy because of the 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.
