Wherein the taper tile is four blocks of toper section of thick bamboo of components of a whole that can function independently, and the circumference evenly distributed, the tapering is the same with the design tapering of coil tip, and the support nail is the threaded rod of taking the bulb. The utility model discloses a rotatory adjustable length of screw thread, bulb top are on the taper tile to adjust the excircle diameter of taper tile, the inner ring is holistic ring, provides holistic supporting role, and this instrument easy operation is convenient, easily dismouting, and the plastic effect is obvious.
Description
The technical field is as follows:
the utility model relates to a motor stator winding tip plastic instrument.
Background art:
along with the development of motor manufacturing technology, the requirements on the carrying process and precision of each part of the motor are higher and higher, the integral performance of the motor can be directly reflected by the carrying quality of each part of the motor, after a stator winding is off-line, the end part of a coil needs to have certain taper, the coil often has deformation under the action of self stress, the taper of the end part of the coil is uneven, and therefore assembly interference or air gaps are uneven, the use performance and the service life of the motor are affected, and the motor needs to be calibrated by a special tool. Current coil plastic instrument can only carry out the school type work to coil list one by one, takes trouble hard, and manual operation is inhomogeneous hard, and the plastic effect is not obvious, and this patent application frock can carry out the bulk operation to the coil tip, and the coil tip atress is even, and easy operation is in the aspect of, and the plastic effect is good.
The invention content is as follows:
the utility model aims at providing a can accomplish stator winding smoothly and roll off the production line and accomplish the tapered motor stator winding tip plastic instrument of back coil end, guarantee the tapered precision of winding coil end to improve the whole precision that the motor was made. The utility model adopts the following technical scheme: a motor stator winding end shaping tool comprises conical tiles 1, supporting nails 2 and an inner ring 3, wherein the conical tiles 1 are 90-degree tiles with tapers on the outer arc surfaces, the four conical tiles 1 form a unified integral conical cylinder, the outer taper is the same as the design taper of the coil end, the inner wall of the conical cylinder is cylindrical, mounting holes 4 are formed in the inner wall of the conical cylinder, and the mounting holes 4 are matched and assembled with the spherical surfaces of the supporting nails 2; the supporting nail 2 is a single-end screw with a ball head, one side of the thread of the supporting nail 2 is connected with the inner ring 3, one side of the ball head of the supporting nail 2 is jacked in the mounting hole 4 on the inner wall of the taper tile 1, and the outer hexagon of the thread part and the transition part of the ball head part on the supporting nail 2 is processed.
The inner ring 3 is an integral circular ring, four threaded holes 5 are formed in the outer side of the circular ring, and the threaded holes 5 are assembled with the threaded parts on the support nails 2.
The utility model discloses a theory of operation:
the supporting nails are sequentially screwed on the inner ring, the screwed inner ring is placed at the end part of the winding, the four conical tiles are sequentially placed at the end part of the winding, the supporting nails are in contact with the inner wall of the conical tiles, the supporting nails are rotated to lengthen the length of the supporting nails, so that the supporting nails push the tiles to move outwards along the radial direction, the conical surfaces of the conical tiles abut against the end part of the winding, and the purpose of shaping the taper of the end part of the winding is achieved.
The specific use of the tool can be referred to the following examples: the supporting nails are sequentially screwed on the inner ring, the screwed inner ring is placed at the end part of the winding, the four conical tiles are sequentially placed at the end part of the winding, the supporting nails are in contact with the inner wall of the conical tiles, the supporting nails are rotated to lengthen the length of the supporting nails, so that the supporting nails push the tiles to move outwards along the radial direction, the conical surfaces of the conical tiles abut against the end part of the winding, and the purpose of shaping the taper of the end part of the winding is achieved.
The utility model has the advantages that:
the transition part of the thread and the ball head is provided with an outer hexagon, so that the spanner 2 of the support nail can be conveniently rotated.
The accurate coil taper is provided, the stress of the coil is removed after the shaping of the tool, the secondary deformation is avoided, the shaping effect is obvious and effective, the coil inserting precision is guaranteed, the uniformity of an air gap of a final assembly motor is never guaranteed, and the vibration or abnormal sound caused by the uneven air gap at the end part is avoided being overlarge. The cone cylinder adopts a split type structure, so that the tool can be conveniently mounted and dismounted, the operation difficulty of an operator is reduced, and the abutting contact surface adopts a ball head structure, so that the friction force generated by contact is reduced.
