Description

Technical Field

[0001] The invention relates to the technical field of motor stator processing, in particular to a three-phase asynchronous motor stator press-fitting positioning device. Background Art

[0002] The three-phase asynchronous motor is a type of electric motor that is powered by a 380V three-phase AC power supply. Since the rotor and stator rotating magnetic fields of the three-phase asynchronous motor rotate in the same direction and at different speeds, there is a slip rate, so it is called a three-phase asynchronous motor. The existing stator and casing assembly technologies are divided into press mounting and thermal mounting; the press mounting method is: place the stator on the tooling, the stator power cord in the U-shaped groove, then buckle the casing on the stator core, and then turn on the hydraulic press to press the casing in.

[0003] In the existing technical scheme, a publication number: CN213717803U is proposed, which is a high-efficiency three-phase asynchronous motor stator press-fitting positioning device, including a positioning table, a placement cavity is opened on the positioning table, a plurality of buffer springs are fixedly connected to the lower end raised surface of the placement cavity, and the plurality of buffer springs are commonly fixedly connected to a positioning plate, a trigger switch is arranged between the positioning plate and the lower end raised surface of the placement cavity, a warning light is arranged on the positioning table, and the warning light is electrically connected to the trigger switch, a bracket is fixedly connected to the positioning table, and a press body is arranged on the bracket.

[0004] In order to solve the problem that during the press-fitting process, the degree of stator pressing is generally estimated by visual observation, which greatly affects the problem of stator press-fitting accuracy, the prior art uses conductive blocks and conductive sheets to cooperate with positioning plates to locate the stator pressing depth. When the stator is pressed to the required depth, the conductive blocks and conductive sheets will dock to turn on the circuit of the warning light. The warning light gives the staff an accurate judgment, which can effectively improve the accuracy of press-fitting. However, there is still a problem that it is difficult to remove the parts after the motor stator press-fitting positioning device is completed, thereby affecting the working efficiency of the device.
