Description

Technical Field

[0001] The present invention relates to the field of direct drive motors, and more particularly to a structure of a permanent magnet direct drive motor with water-air cooling. Background Art

[0002] A direct drive motor is a motor technology that can directly drive a load. It directly couples or connects a new type of rotary motor or linear motor to the driven load to achieve driving without intermediate transmission devices such as gears, belts or chains. According to different motion forms, direct drive motors can be divided into two categories: rotary direct drive motors and linear direct drive motors. A linear direct drive motor, that is, a linear motor, is a motor that directly drives a load to perform linear motion.

[0003] For related technologies, reference can be made to the Chinese utility model patent with the publication number CN220510922U, which discloses a water-cooled linear motor, including a linear motor body and a water-cooling device. The linear motor body includes a base, and a groove is formed in the base. The water-cooling device includes a liquid storage tank. A liquid outlet pipe is fixedly installed on the bottom surface of the liquid storage tank. One end of the liquid outlet pipe is fixedly installed with a connector. One end of the connector is fixedly installed with a cooling pipe. The cooling pipe is arranged in the groove. One end of the cooling pipe is fixedly connected with a return pipe. One end of the return pipe is fixedly connected with a pump body. The output end of the pump body is connected with a liquid inlet pipe. The liquid inlet pipe is fixedly installed on one side of the liquid storage tank. When the switch of the pump body is turned on, the coolant in the liquid storage tank flows through the liquid outlet pipe and the connector into the cooling pipe, then enters the pump body through the return pipe, and finally flows into the liquid storage tank through the liquid inlet pipe for recycling. The coolant in the cooling pipe exchanges heat with the hot air in the groove, thereby dissipating heat from the linear motor.

[0004] In view of the above related technologies, after the cooling pipe is used for a period of time, scale and impurities will adhere to the inner wall of the cooling pipe. At this time, the staff needs to disassemble the cooling pipe from the groove and clean the inside of the cooling pipe. The operation process of the staff is relatively complicated, resulting in a low cleaning effect of the cooling pipe. Summary of the Invention

After the cooling pipe 2 is used for a period of time, the motor 32 is started. The motor 32 drives the cleaning screw 33 to rotate. The cleaning screw 33 drives the driving ring 34 to move. The first electromagnet in the driving ring 34 attracts the first iron block. The driving ring 34 drives the cleaning ring 31 to move. The cleaning ring 31 cleans the scale and impurities on the inner wall of the straight pipe 21, which is convenient for the staff to operate and solves the problem of low cleaning effect of the cooling pipe 2.

The bidirectional screw 36 drives the two separation plates 37 to move away from each other. The two separation plates 37 respectively drive the first arc plate 351 to move, so that the first arc plates 351 move away from each other. At the same time, the shaking mechanism 5 drives the first arc plate 351 to shake, and shakes off the dust adhered to the brush ring 35.

When the two first arc plates 351 contact each other, the storage battery supplies power to the second electromagnet, the second electromagnet attracts the second iron block, the second iron block drives the driving plate 77 to move, and the driving plate 77 drives the square rod 75 to move, so that the square rod 75 is pulled out of the square groove.

[0040] The implementation principle of a water-air cooled permanent magnet direct drive motor structure in an embodiment of the present invention is as follows: After the cooling pipe 2 has been used for a period of time, the motor 32 is started.

And the cleaning gear 331 drives the rotating shaft 71 to rotate, the rotating shaft 71 drives the connecting shaft 213 to rotate, and the connecting shaft 213 drives the second arc plate 311 to rotate. When the two first arc plates 351 and the two second arc plates 311 are all spliced together, the storage battery energizes the first electromagnet and the second electromagnet. The first electromagnet attracts the first iron block, and the second electromagnet attracts the second iron block. The second iron block drives the driving plate 77 to move, the driving plate 77 drives the square rod 75 to be pulled out of the square groove, and at the same time the locking block 62 is pulled out of the insertion groove. The cleaning screw 33 drives the driving ring 34 to move, and the driving ring 34 drives the cleaning ring 31 to move. The cleaning ring 31 cleans the scale and impurities on the inner wall of the straight pipe 21; When the cleaning screw 33 drives the driving ring 34 to return to the initial position, the cleaning gear 331 meshes with the first gear 411, the separating gear 361 meshes with the second gear 421, the cleaning gear 331 meshes with the fifth gear 741. The bidirectional screw 36 drives the two first arc plates 351 to move away from each other. At the same time, the bidirectional screw 36 drives the shaking cam 53 to rotate, and the shaking cam 53 drives the first arc plate 351 to shake, shaking off the dust adhered to the brush ring 35. The rotating shaft 71 drives the square rod 75 to rotate, the square rod 75 drives the connecting shaft 213 to rotate, and the connecting shaft 213 drives the second arc plate 311 to rotate, so that the length direction of the second arc plate 311 is the same as the length direction of the straight pipe 21. During the process of the coolant passing through the straight pipe 21, the influence of the second arc plate 311 on the coolant flow rate is reduced.
