[0002] AC motors are machines used to realize the mutual conversion between mechanical energy and AC electrical energy. Due to the tremendous development of AC power systems, AC motors have become the most commonly used motors. Compared with DC motors, AC motors have no commutator, so they have a simple structure, are easy to manufacture, are relatively strong, and can be easily made into high-speed, high-voltage, high-current, and large-capacity motors. AC motors cover a wide range of power, and an AC motor rotor installation tool is required when assembling AC motors.

[0003] Currently, when installing a single AC motor rotor and a housing, the user is required to first fix the housing and then insert the AC motor rotor into the housing from one end. Manual operation is cumbersome and requires reliance on experience. Some patents propose a structure that can coaxially align the AC motor rotor and the housing, but the structure is relatively complex, with more power parts and a higher cost of use.

It enters into two adjacent side plates 3, the cover plate 5 is used to limit the top surface of the bottom installation of the AC motor housing to prevent it from tilting, the electric cylinder 6 is used to control the lateral movement of the motor rotor, the slide groove 7 is used to guide the roller 15, the fixing piece 8 is used to fix the motor rotor, the convex portion 9 is used to abut and limit one side of the outer end surface of the motor rotor, and the fixing hole 10 is used to insert the rotor shaft end. During installation, first place the AC motor housing on the mounting plate 1, push the front and rear sides of its bottom installation respectively to insert between the side plates 3 until one end surface conflicts with the baffle 2, and then insert the motor rotor shaft end into the fixing hole 10 until one side conflicts with the convex portion 9, and then connect the tooling to an external power supply, control the electric cylinder 6 to work through the controller, and push the fixing piece 8 through the output end of the electric cylinder 6 to drive the motor rotor to move and insert into the AC motor housing to complete the installation of the rotor. By setting the limit assembly and the push assembly, the housing can be assisted in positioning when installing a single AC motor rotor, and then the rotor can be installed by driving the electric cylinder 6. The whole installation process is simple to operate and easy to use. Under the premise of also achieving the coaxial alignment of the rotor and the housing, the tooling only uses one power part as a whole.
