Embodiment Construction

[0021] The present invention is described in detail below in conjunction with accompanying drawing:

[0022] An assembly tooling for a squirrel-cage motor rotor guide bar, comprising a rotor core 1, on the rotor core 1, an inverted T-shaped through hole 2 for inserting the guide bar is provided, and a rectangular The through hole 3, the rectangular through hole 3 and the inverted T-shaped through hole 2 are connected together. In the inverted T-shaped through hole 2, a guide bar 4 and a left wedge-shaped steel bar 5 are inserted from the left side of the rotor core 1. Inserted into the rectangular through-hole 3, the right wedge-shaped steel bar 6 is inserted into the rectangular through-hole 3 from the right side of the rotor core 1, the upward wedge-shaped surface of the left wedge-shaped steel bar 5 and the upward wedge-shaped surface of the right wedge-shaped steel bar 6 The lower wedge faces fit together.

[0023] After the rotor core 1 and the rotating shaft 7 are assem...

Abstract

The invention discloses an assembly tool of a rotor guide bar of a squirrel cage motor and an assembly method of the rotor guide bar, and solves the problem that the guide bar and a guide bar insertion groove are not tightly wedged in the existing motor rotor assembly. The assembly tool comprises a rotor iron core (1), wherein an inverted T-shaped through hole (2) allowing the guide bar to be inserted is formed in the rotor iron core (1); a rectangular through hole (3) is formed in the inner side of the inverted T-shaped through hole (2); the rectangular through hole (3) communicates with the inverted T-shaped through hole (2); the guide bar (4) is inserted into the inverted T-shaped through hole (2); a left wedge-shaped steel bar (5) is inserted into the rectangular through hole (3) from the left side surface of the rotor iron core (1); a right wedge-shaped steel bar (6) is inserted into the rectangular through hole (3) from the right side surface of the rotor iron core (1); and an upward wedge-shaped surface of the left wedge-shaped steel bar (5) is matched with a downward wedge-shaped surface of the right wedge-shaped steel bar (6). The assembly quality of the motor rotor is greatly improved.

Description

technical field [0001] The invention relates to an assembly tool for a rotor guide bar of a squirrel-cage motor, in particular to an assembly tool for the guide bar in assembling the rotor of a squirrel-cage motor and an assembly method for the rotor guide bar. Background technique [0002] The rotor core of the squirrel-cage motor is formed by stacking the rotor punches, and an inverted T-shaped through hole is punched out along the outer circumference of each punched sheet. After the punched sheets are stacked, the inverted T-shaped through holes form the rotor guide The existing assembly process is to insert the conductive copper strip into the guide bar insertion slot from one side of the iron core. After the guide bar is inserted, there is generally a gap between the guide bar and the guide bar insertion slot. The bar and the iron core are fixed as a whole, so that the guide bar will not shake in the guide bar insertion slot when the rotor rotates, so as to avoid the br...
