Description
Technical field
The present invention relates to from stator two ends seam, inner circle datum axis unshakable in one's determination be calibrated to the circular runout method, be applied to indirectly measure the radial run-out amount of stator core inner circle to two ends seam common reference axis.
Background technology
In the appendix E of " middle and small motor product quality grade general rule " to project: the check of " radial run-out of stator core inner circle to two ends seam common reference axis ", the cubing of using is circle jump measuring instrument and seam mould; The method of inspection is: the stator two ends gapless seam mould of beating in ordinatedly, measuring instrument is abutted against to seam mould internal circular surfaces, both keep good contact, measuring instrument returns and circles stator, measure equably some points (being no less than 8 points) on two cross sections of distance stator core end face 10～20mm with dial gauge, get on two cross sections and record the reading maximum difference is the radial run-out amount of stator core inner circle to two ends seam common reference axis.
This measuring method weak point is: the one, and the seam mould that gapless coordinates should be corresponding one by one with the seam of tested stator, accomplish that the correspondence expense of taking a lot of work is expected very much one by one.The 2nd, stator core is to be overrided to form by thin punching, and irregular degree is larger, and the numerical value of measuring on two cross sections of distance stator core end face 10～20mm only reflects the situation of " two cross section on ", can not represent the stator core inner cylinder face.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point of the prior art, providing a kind of contains the stator core inner cylinder face and determines its axis, measure that the two ends seam uses the radial run-out amount of this axis, and then indirect determination stator core inner circle inner circle datum axis unshakable in one's determination is calibrated to the circular runout method from stator two ends seam the radial run-out amount of two ends seam common reference axis.
Purpose of the present invention can reach by following technical proposals:
From stator two ends seam, inner circle datum axis unshakable in one's determination is calibrated to the circular runout method, it is characterized in that using cubing to contain the stator core inner cylinder face, allow cubing axle two ends central axis on stator core inner cylinder face center line, then the radial run-out amount of routine measurement two ends seam to cubing axle two ends central shaft; Described cubing is comprised of axle, resilient sleeve, trim ring, axle nut and scalariform screw; Axle middle part band male cone (strobilus masculinus), male cone (strobilus masculinus) pitch angle 1 degree; Resilient sleeve is cylindrical, and the diameter of its external cylindrical surface is slightly less than the diameter of stator core inner cylinder face; The axial two way alternate of resilient sleeve is outputed the groove gap do not run through body is divided equally along circumference; The inner conical surface of resilient sleeve coordinates with the male cone (strobilus masculinus) of axle; The axle nut is spun on axle through the center hole of trim ring, and trim ring is constrained in the annular groove outside of axle nut with two nuts, the trim ring spindle nut rotation of not following one's inclinations; Trim ring connects mutually by scalariform screw and resilient sleeve annular end face.
The present invention has following advantage: cubing is simple in structure, measures easy to operate.Measuring basis changes " the two ends seam is to inner circle datum axis unshakable in one's determination " into by " inner circle unshakable in one's determination is to two ends seam common reference axis " in theory, and check data more intuitively, more can reflect actual state.The two ends central shaft right alignment of resilient sleeve cylindrical and axle reaches 0.005mm, thereby the two ends central shaft right alignment of stator core inner circle and axle also can reach 0.005mm.
