Description

Technical Field

[0001] The utility model relates to the technical field of pole shoe processing and positioning, in particular to a pole shoe processing and positioning tool. Background Art

[0002] The pole shoe is a unique structure of electromagnets, permanent magnets and motor poles. Some people call it the pole head. It is an indispensable part of electromagnets and permanent magnets. The outer surface of the pole shoe is an arc surface. In order to ensure that the outer surfaces of all assembled pole shoes are on the same circle, it is usually necessary to process the arc surfaces of all rotor pole shoes through positioning tooling so that the arc surfaces of all rotor pole shoes are located in the same circle. Some pole shoes are processed and positioned by tooling. A number of limit slides parallel to the axis are evenly arranged on the circumferential surface of the cylindrical seat. The two ends of the limit slide are connected with the two ends of the cylindrical seat. A pole shoe positioning seat is arranged in each limit slide, and a pole shoe slot is arranged on the outer side of the pole shoe positioning seat. A threaded hole is arranged at the bottom of the pole shoe slot, and a number of through holes are arranged between the two end faces of the cylindrical seat. A connecting rod is provided in the through hole, and a lower limit ring fixed to the connecting rod is provided on the lower end surface of the cylindrical seat, and an upper limit ring is provided on the upper end surface of the cylindrical seat. The upper end of the connecting rod is a screw portion, which passes through the upper limit ring and is locked by a nut. When in use, the pole shoe is limited by vertical sliding. Since the width of the open end of the pole shoe slot is smaller than the bottom width of the pole shoe slot, the pole shoe cannot be removed radially after being installed in the pole shoe slot (it can only be pulled out from the upper and lower ends of the pole shoe slot). Subsequently, the pole shoe is vertically limited by thread locking through the screw nut. However, the pole shoe slot structure of the device is fixed, and only a certain model of pole shoe can be processed and positioned. When the model and size of the pole shoe changes, the positioning tooling corresponding to the pole shoe slot needs to be replaced. The operation is cumbersome and the cost is high, which needs to be improved. Utility Model Content

As the locking stud 11 is gradually tightened, the vertical fixing seat 10 moves downward and squeezes the upper side of the pole shoe 5, thereby completely processing and limiting the pole shoe 5. The device can process and position pole shoes 5 of different models, and the processing and positioning of the pole shoe 5 has a wide range of applications and is easy to use.
