Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a magnetic steel clamping device. Background Art

[0002] The motor is mainly composed of a rotor and a stator. The common rotor core adopts an inserted magnetic steel block structure. A magnetic steel block made of permanent magnet material is inserted into the rotor core as the rotating mechanism of the motor. It interacts with the rotating magnetic field generated by the stator to make the rotor rotate and generate the output of the motor.

[0003] The magnetic steel clamping device provided by the publication number "CN220282784U" includes a clamping assembly, which includes two clamping members, and the two clamping members are used to clamp the magnetic steel, a guide assembly, and the two clamping members are arranged on the guide assembly, and the guide assembly is used to guide the two clamping members, and a driving assembly, and the driving assembly is used to drive the two clamping members to move along the axial direction of the guide assembly so that the two clamping members are close to each other and clamp the magnetic steel. This patented technology can be inserted into the mounting hole of the flywheel rotor, and the two clamping members are aligned with the magnetic steel to be clamped, and then the two clamping members are driven to approach each other through the driving assembly to clamp the magnetic steel, and then the magnetic steel is taken out of the mounting hole, which is simple and convenient to operate.

[0004] However, the above device still has the following problems during implementation:

[0005] For example, the most widely used fixing method in the motor industry is to use glue to fix the magnet in the mounting hole, while the clamping device uses a two-side clamping and upward pull-out method. The force direction is inconsistent with the pull-out direction, which makes the pull-out more difficult and easy to slip, and thus requires a greater clamping force. The magnet itself is brittle and easily broken in the mounting hole, affecting the clamping efficiency. Utility Model Content

[0028] First, the two positioning rods 302 are driven to move by rotating the handle 303 so that the distance between the two positioning rods 302 is greater than the distance between the magnets. Then, the bottom of the positioning rod 302 is inserted into the mounting hole by holding the grip groove 9 so that the two positioning rods 302 are located on both sides of the magnet.
