[0002] A permanent magnetic fixed chuck is a device that uses the magnetism of permanent magnetic materials to fix the workpiece. It is usually composed of permanent magnetic materials, iron cores, etc. Its working principle is to tightly adsorb the metal workpiece through the magnetic field generated by the permanent magnetic material to achieve the fixing effect.

[0003] In the prior art, the traditional permanent magnetic fixed suction cup will cause internal heat when in use due to the need to frequently pass current. In order to prevent the internal coil from being damaged due to high temperature, it is necessary to dissipate heat. The traditional heat dissipation method is a passive heat dissipation method with a filter net, which has a poor heat dissipation effect. Therefore, the utility model proposes an electric permanent magnetic fixed suction cup to solve the above problem. Utility Model Content

[0011] Preferably, a dust removal blade is fixedly sleeved on the lower end of the driving rod, and the dust removal blade passes through the magnetic core and is located in the through hole.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. By setting up a heat dissipation mechanism, during use, the output shaft of the driving motor rotates, driving the driving rod to rotate, thereby driving the rotating plate to rotate with the driving rod as the axis, thereby driving the two rotating rods and the two heat dissipation fan blades to rotate with the driving rod as the axis. Under the action of the ring gear, the gear meshing with it rotates, thereby driving the rotating rod and the heat dissipation fan blades to rotate, thereby achieving heat dissipation for the coil and the magnetic core to avoid damage caused by excessive temperature.

[0014] 2. By setting a driving rod and dust removal blades, the output shaft of the motor rotates during use, driving the driving rod to rotate, thereby driving the dust removal blades to rotate.
