Abstract
The utility model relates to a measurement tool for radial runout amount of a core inner circle to two end spigot of a stator, which is applied for measuring radial runout amount of the core inner circle to a common reference axis of two end spigots. The measurement tool is composed of the following components: a mandrel, an elastic tool, a pressure ring, a mandrel nut and a step-shaped screw. The middle part of the mandrel is provided with an outer conical surface. The inclination angle of the outer conical surface is 1 DEG. The elastic sleeve is cylindrical. The diameter of an outer cylindrical surface of the elastic sleeve is slightly smaller than the diameter of an inner cylindrical surface of a stator core. Non-through slots which are bidirectionally and alternatively arranged are provided in the axial direction of the elastic sleeve for equally dividing the sleeve body along the circumference. The inner conical surface of the elastic sleeve is matched with the outer conical surface of the mandrel. The mandrel nut passes through a central circular hole of the pressure ring and is screwed on the mandrel. Furthermore the pressure ring is restrained in outer circle grooves of the mandrel nut through two nuts. The pressure ring does not rotate along with the mandrel nut. The pressure ring is connected with an annular end surface of the elastic sleeve through a step-shaped screw. The measurement tool provided by the utility model has advantages of: simple structure, convenient operation, high coaxiality which reaches up to 0.005mm between the inner circle of the stator and diameter at two ends of the mandrel.
Description
Technical field
The utility model relates to the measurement apparatus of stator two ends seam to inner circle radial run-out amount unshakable in one's determination, is applied to measure the radial run-out amount of stator core inner circle to two ends seam common reference axis.
Background technology
< < middle and small motor product quality is graded in the appendix E of general rule > > to project: the check of " radial run-out of stator core inner circle to two ends seam common reference axis ", and 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, with dial gauge, on two cross sections apart from stator core end face 10～20mm, measure equably some points (being no less than 8 points), get and record reading maximum difference on two cross sections is the radial run-out amount of stator core inner circle to two ends seam common reference axis.
Its deficiency 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 apart from stator core end face 10～20mm only reflects the situation in " on two cross sections ", can not represent stator core inner cylinder face.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point of the prior art, provide a kind of and contain stator core inner cylinder face and determine its axis, the measurement apparatus of the stator two ends seam that measurement two ends seam is used the radial run-out amount of this axis to inner circle radial run-out amount unshakable in one's determination.
The purpose of this utility model can reach by following technical proposals: the measurement apparatus of stator two ends seam to inner circle radial run-out amount unshakable in one's determination, is characterized in that being 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 not running through body is divided equally along circumference; The inner conical surface of resilient sleeve coordinates with the male cone (strobilus masculinus) of axle; Axle nut is spun in 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 utlity model has following advantage: simple in structure, easy to operate.Measuring basis changes " 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 diameter of axle right alignment of resilient sleeve cylindrical and axle reaches 0.005mm, thereby the two ends diameter of axle right alignment of stator core inner circle and axle also can reach 0.005mm.

Embodiment
The utility model is further described below in conjunction with accompanying drawing.The measurement apparatus of stator two ends seam to inner circle radial run-out amount unshakable in one's determination, is characterized in that being comprised of axle (3), resilient sleeve (1), trim ring (11), axle nut (15) and scalariform screw (9); Axle (3) middle part band male cone (strobilus masculinus) (5), male cone (strobilus masculinus) pitch angle 1 degree; Resilient sleeve (1) 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 (17) not running through body is divided equally along circumference; The inner conical surface of resilient sleeve coordinates with the male cone (strobilus masculinus) of axle (5); Axle nut (15) is spun in axle (3) through the center hole of trim ring (11), and with two round nuts (13), trim ring (11) is constrained in the annular groove outside of axle nut (15), trim ring (11) spindle nut (15) of not following one's inclinations rotates; Trim ring (11) connects mutually by scalariform screw (9) and resilient sleeve (1) annular end face.
After the utility model assembling, the two ends diameter of axle right alignment of the external diameter of resilient sleeve (1) and axle (3) is less than 0.005mm.Thereby the two ends diameter of axle right alignment of stator core inner circle and axle also can reach 0.005mm.During use, the external cylindrical surface of resilient sleeve contacts with stator core inner cylinder face total length, the axle that turns clockwise nut (15), trim ring (11) is close to the right side of resilient sleeve, axle (3) moves right, the conical surface swell resilient sleeve external diameter coordinating with resilient sleeve by axle, is adjacent to the cylindrical of resilient sleeve and stator core inner circle.Now the external cylindrical surface of resilient sleeve is exactly the containing face of cylinder of cylinder in stator core, and the two ends diameter of axle line of axle is exactly the axis of cylinder in stator core.With Centigrade scale, measure stator two ends seam I(23 respectively) and seam II(25) distance of the two ends diameter of axle of center roller, every end is measured some points (being no less than 8 points) equably, and getting two ends, record reading maximum difference be that stator two ends seam is to stator core inner circle radial run-out amount.
Be rotated counterclockwise nut, by trim ring, scalariform screw, axle and resilient sleeve disengaged, resilient sleeve and stator core inner circle are unclamped, and can unload apparatus.
