Abstract
A kind of motor rotor core press mounting tool, belongs to electrical machmary maintenance equipment technical field, for press-fiting the motor rotor core loosened.Its technical scheme is: it is made up of chassis, connector, pull bar, connector is welded on chassis along chassis circumference chassis edge is uniform, connector position is corresponding with rotor vent locations, there is crotch one end of pull bar, and the other end of pull bar is connected with connector by connecting bolt.Rotor catches on through rotor ventilation hole by pull bar front end of the present utility model, and back end of tie rod is connected with chassis by connector, and chassis card is fixed, and mandril of lifting jack withstands on rotor through center chassis hole and compressed by rotor core.The utility model structure is simple, easy to use, enterprise can be made to complete keep in repair the compression of motor rotor core, change motor rotor core loosens the present situation that rear motor can only be scrapped, and avoids causing great waste, reduce the production cost of enterprise, there is significant economic benefit.
Description
Technical field
The utility model relates to a kind of instrument press-fited motor rotor core, belongs to electrical machmary maintenance equipment technical field.
Background technology
In steel rolling equipment, steel plate transmission drive motors-electric machines for roller restrict by running environment and service conditions, occur that looseness of electric motor rotor, iron loss increase cacophonia when causing motor to run, temperature rise is too high, even motor is burnt out time serious, electric machines for roller fault is caused to roll off the production line maintenance, iron core need be loosened to electric machines for roller during maintenance again to press-fit, guarantee that electric machines for roller normally use.The maintenance condition of current general iron and steel enterprise and equipment can not complete the compression maintenance of motor rotor core, motor can only be made to scrap, cause great waste, improve the production cost of enterprise once occur that motor rotor core loosens.Therefore, it is very necessary for developing a kind of instrument that can press-fit motor rotor core.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of motor rotor core press mounting tool, this press mounting tool can to press-fit motor rotor core by matching with other general maintenance of equipment, overcome the defect that cannot press-fit motor rotor core at present, scrap because rotor core loosens to avoid motor, reduce the production cost of enterprise, increase economic efficiency.
The technical scheme solved the problems of the technologies described above is:
A kind of motor rotor core press mounting tool, it is by chassis, connector, pull bar, connecting bolt forms, chassis is steel disc, there is centre bore at the center on chassis, connector is multiple rectangle blooms, one end of cast steel roll cuboid is vertically welded on chassis, the position of connector on chassis is corresponding with the vent locations of rotor, the other end of connector cuboid has connecting screw hole, pull bar is steel stock, quantity and the connector of pull bar match, there is crotch one end of pull bar, the other end of pull bar has the connecting screw hole of connecting screw hole and connector to match, connector is connected with pull bar by connecting screw hole by connecting bolt.
Above-mentioned motor rotor core press mounting tool, described connector and pull bar are respectively 3-4, connector on chassis circumferentially uniformly at intervals, the long axis normal of the connecting screw hole on connector and connector cuboid, the screw of pull bar one end and the body of rod long axis normal of pull bar.
Above-mentioned motor rotor core press mounting tool, the diameter in described center chassis hole is greater than mandril of lifting jack diameter.
Above-mentioned motor rotor core press mounting tool, the diameter of described pull bar is less than the internal diameter of rotor ventilation hole, and the length of pull bar is greater than the length of rotor.
The beneficial effects of the utility model are:
Motor rotor core catches on through rotor ventilation hole by pull bar front end of the present utility model, and back end of tie rod is connected with chassis by connector, and chassis card is fixed, and mandril of lifting jack withstands on rotor through center chassis hole and compressed by rotor core.The utility model structure is simple, easy to use, general enterprise can be made to complete keep in repair the compression of roller bed motor rotor core, change motor rotor core loosens the present situation that rear motor can only be scrapped, avoid causing great waste, reduce the production cost of enterprise, there is significant economic benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2,3 is front view and the end view on chassis;
Fig. 4,5 is front view and the end view of connector;
Fig. 6,7 is front view and the end view of pull bar.
In figure, mark is as follows: motor shaft 1, iron core bracing frame 2, iron core 3, iron core retainer ring 4, chassis 5, connector 6, pull bar 7, centre bore 8, connecting screw hole 9, crotch 10.
Embodiment
The utility model is made up of chassis 5, connector 6, pull bar 7, connecting bolt.
Show in figure, chassis 5 is steel disc, and there is centre bore 8 at the center on chassis 5, and the diameter of centre bore 8 is greater than mandril of lifting jack diameter.The chassis 5 of an embodiment of the present utility model is made by 30mm steel plate.
Show in figure, connector 6 is 3-4 rectangle bloom, connector 6 is uniform at edge, chassis 5 along chassis 5 circumference, one end of connector 6 cuboid is vertically welded on chassis 5, the position of connector 6 on chassis 5 is corresponding with the vent locations of rotor, the other end of connector 6 cuboid has connecting screw hole 9, the long axis normal of connecting screw hole 9 and connector 6 cuboid.
Show in figure, pull bar 7 is steel stock, and quantity and the connector 6 of pull bar 7 match, and the diameter of pull bar 7 is less than the internal diameter of rotor ventilation hole, and the length of pull bar 7 is greater than the length of rotor.There is crotch 10 one end of pull bar 7, the other end of pull bar 7 has connecting screw hole, the body of rod long axis normal of connecting screw hole and pull bar 7, the connecting screw hole of pull bar 7 and the connecting screw hole 9 of connector 6 match, and connector 6 is connected with pull bar 7 by connecting screw hole by connecting bolt.
Use procedure of the present utility model is as follows:
3 or 4 connectors 6 are welded on chassis 5 according to rotor vent locations is uniform.
Be connected with connector 6 with connecting bolt respectively the rear end of 3 or 4 pull bars 7, pull bar 7 is through rotor ventilation hole, and iron core retainer ring 4 catches on from the outside of iron core retainer ring 4 by the crotch 10 of pull bar 7 front end.
Catch chassis 5 with vehicular pulley extractor, mandril of lifting jack head withstands motor shaft 1 by the centre bore 8 on chassis 5, and operation vehicular pulley extractor makes pull bar 7 be acted on rotor core 3 by iron core retainer ring 4, thus compresses the iron core 3 loosened.
