Description

Technical Field

[0001] The utility model relates to the technical field of stator installation tooling, and more specifically to a tooling for installing a rotor with permanent magnets into a stator. Background Art

[0002] The motor rotor is a rotating component in the motor. The motor consists of two parts, the rotor and the stator. It is a device for realizing the conversion between electrical energy and mechanical energy and between mechanical energy and electrical energy. The motor rotor is divided into a motor rotor and a generator rotor. When installing the rotor into the machine base with a stator, it is generally done manually by inserting the central axis of the rotor into one end inside the machine shell, and then rotating the rotor to install it in the stator inside the machine base. However, the rotor with permanent magnets has a very large magnetic force and is easily attracted to the inner circle of the stator. At this time, it is basically impossible to rely on manual methods. Therefore, special assembly tooling is currently used to install the rotor.

[0003] For example, a stator and rotor assembly tooling for a permanent magnet servo motor with the publication number CN220822853U in the prior art. This utility model enables the iron core of the rotor to be smoothly installed into the inner cavity of the stator by axially moving the stator relative to the rotor. The rotor and the stator are respectively restricted by the coupling and the radial fixing structure and will not be affected by magnetic attraction and have radial displacement, preventing the iron core and permanent magnets of the rotor from contacting and rubbing against the inner wall of the stator and causing damage.

[0004] However, the above prior art still has the following problems when in use: When using the support block to support the installation of the permanent magnet rotor and the stator, since the sizes of the permanent magnet rotors of different-sized motors are also different, and the support block cannot be adjusted, it is impossible to apply to permanent magnet rotors of different sizes, and there are limitations in use. At the same time, when moving the permanent magnet rotor, it is easy to shake, which will affect the installation accuracy of the permanent magnet rotor and the stator. Based on this, the utility model provides a tooling for installing a rotor with permanent magnets into a stator. Summary of the Utility Model

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a tooling for installing a rotor with permanent magnets into a stator. Through the cooperation of the front sliding seat, the rear sliding seat and the V-shaped block, the permanent magnet rotor is accurately installed in the stator machine base. At the same time, a driving component is used to drive two clamping plates to clamp the permanent magnet rotor, thereby improving the stability of the placement of the permanent magnet rotor. When the V-shaped block moves to adjust the center of the permanent magnet rotor and the stator, it can prevent the permanent magnet rotor from shaking, so as to solve the problems that appear in the above background art.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A tooling for installing a rotor with a permanent magnet into a stator, including a base. A front sliding seat, a V-block, a stator fixing table, and a rear sliding seat are sequentially arranged on the top of the base from front to back.

A driving component for driving the two round rods to rotate is arranged inside the V-block. Electric push rods are fixedly penetrated through the interiors of both the front sliding seat and the rear sliding seat.

The rear end of the output shaft of the first motor penetrates through the V-block and is fixed to the front end of the first rotating rod.

[0008] In a preferred embodiment, a cavity for placing the driving component is arranged inside the V-profile.

[0009] In a preferred embodiment, sliders are connected to the bottoms of both the V-block and the stator fixing table through two second electric push rods. The two sliders are both slidably arranged on the top of the base. Using the sliders to support the V-block and the stator fixing table facilitates adjusting the positions of the V-block and the stator fixing table.

[0010] In a preferred embodiment, positioning feet adapted to the stator base are fixedly arranged at the four corners of the top of the stator fixing table, facilitating the quick installation of the stator base.

[0011] In a preferred embodiment, a plurality of lead screws are rotatably arranged inside the base. Nut blocks are sleeved on each lead screw.
