Description

Technical Field

[0001] This invention relates to the field of direct drive motors, and more particularly to a water-air cooled permanent magnet direct drive motor structure. Background Technology

[0002] Direct drive motors are a type of motor technology that can directly drive a load. They directly couple or connect a new type of rotary motor or linear motor to the driven load to achieve drive, without the need for intermediate transmission devices such as gears, belts, or chains. According to the different motion forms, direct drive motors can be divided into two main categories: rotary direct drive motors and linear direct drive motors. Linear direct drive motors, also known as linear motors, are motors that directly drive a load to perform linear motion.

[0003] For related technology, please refer to Chinese Utility Model Patent No. 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 with a groove inside. The water-cooling device includes a liquid storage tank, with an outlet pipe fixedly installed on the bottom surface of the liquid storage tank. A connector is fixedly installed at one end of the outlet pipe, and a cooling pipe is fixedly installed at the other end of the connector. The cooling pipe is located in the groove, with a return pipe fixedly connected at one end and a pump body fixedly connected at the other end. The output end of the pump body is connected to an inlet pipe, which is fixedly installed on one side of the liquid storage tank. When the pump body is turned on, the coolant in the liquid storage tank flows through the outlet pipe and connector into the cooling pipe, then enters the pump body through the return pipe, and finally flows back to the liquid storage tank through the 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] Regarding the aforementioned technologies, after a period of use, scale and impurities will accumulate on the inner wall of the cooling pipes. At this time, workers need to disassemble the cooling pipes from the tank and clean the inside of the cooling pipes. The operation process is relatively complicated, resulting in a low cleaning effect of the cooling pipes. Summary of the Invention

At the same time, the shaking mechanism 5 drives the first arc plate 351 to shake, shaking off the dust adhering to the brush ring 35.

[0037] Reference Figures 4 to 6 One end of the cleaning screw 33 is provided with a smooth section.

[0039] Reference Figures 6 to 8 The inner top surface of the groove 11 is provided with an installation groove 111. The locking mechanism 6 includes a locking spring 61 fixedly connected to the inner top surface of the installation groove 111 and a locking block 62 placed in the installation groove 111.

The end face of the locking block 62 facing the plug groove 341 is formed with a locking slope. An L-shaped connecting rod 63 is fixedly connected to the locking block 62. The bottom of the L-shaped connecting rod 63 is formed with a hemispherical surface. The separation plate 37 can contact the hemispherical surface. When the two separation plates 37 move away from each other, the separation plates 37 separate from the hemispherical surface. The locking spring 61 pushes the locking block 62 to move, so that the locking block 62 is inserted into the plug groove and locks the drive ring 34. When the cleaning screw 33 reverses, the two first arc plates 351 are spliced ​​together first.

[0040] Reference Figures 4 to 11The cleaning ring 31 consists of two semi-circular second arc plates 311, both of which are elastic plates. Two sliding grooves 211 are formed on the inner wall of the straight tube 21.

At this time, the rotating mechanism 7 drives the connecting shaft 213 to rotate. 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.

The axis of the square rod 75 is the same as the axis of the rotating shaft 71. A spacer for the square rod 75 is provided on the end face of the connecting shaft 213. The square groove 5 is inserted, and the sliding groove 211 is equipped with a driving component for moving the square rod 75. When the driving ring 34 moves to the smooth section on the cleaning screw 33, the driving component drives the square rod 75 to insert into the square groove. The cleaning gear 331 meshes with the fifth gear 741. The cleaning gear 331 drives the fifth gear 741 to rotate. The fifth gear 741 drives the fifth rotating shaft 74 to rotate.

The third rotating shaft 72 drives the rotating shaft 71 to rotate. The rotating shaft 71 drives the square rod 75 to rotate.

[0043] Reference Figures 9 to 11 A drive groove 711 for sliding a square rod 75 is provided on the end face of the rotating shaft 71. A drive spring 76 is fixedly connected between the inner wall of the drive groove 711 and the square rod 75.

The second electromagnet is electrically connected to the battery and the first electromagnet respectively through wires. When the two first arc plates 351 move away from each other, the battery de-energizes the second electromagnet, and the drive spring 76 pushes the square rod 75 to move, so that the square rod 75 is inserted into the square groove. When the two first arc plates 351 contact each other, the battery energizes the second electromagnet, and the second electromagnet attracts the second iron block. The second iron block drives the drive plate 77 to move, and the drive plate 77 drives the square rod 75 to move, so that the square rod 75 is pulled out of the square groove.

[0044] The implementation principle of a water-air cooled permanent magnet direct drive motor structure in this embodiment of the invention is as follows: After the cooling pipe 2 has been used for a period of time, the motor 32 is started. The motor 32 drives the cleaning screw 33 to rotate, and the cleaning screw 33 drives the cleaning gear 331 to rotate. At this time, the locking block 62 locks the drive ring 34. The cleaning gear 331 drives the bidirectional screw 36 to rotate. The bidirectional screw 36 drives the two first arc plates 351 to move closer to each other. The cleaning gear 331 drives the rotating shaft 71 to rotate, and the rotating shaft 71 drives the connecting shaft 213 to rotate. 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 spliced ​​together, the battery powers 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 drive plate 77 to move. The drive plate 77 drives the square rod 75 to be pulled out of the square slot. At the same time, the locking block 62 is pulled out of the insertion slot. Pulling out the screw 33 causes the drive ring 34 to move, which in turn causes 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 screw 33 drives the drive ring 34 back to its initial position, the cleaning gear 331 meshes with the first gear 411, the disengagement gear 361 meshes with the second gear 421, and the cleaning gear 331 meshes with the fifth gear 741. The bidirectional screw 36 causes the two first arc plates 351 to move away from each other. At the same time, the bidirectional screw... 36 drives the vibrating cam 53 to rotate, which in turn drives the first arc plate 351 to vibrate, shaking off the dust adhering to the brush ring 35. The rotating shaft 71 drives the square rod 75 to rotate, which in turn drives the connecting shaft 213 to rotate. 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. This reduces the influence of the second arc plate 311 on the flow rate of the coolant as it passes through the straight pipe 21.

[0045] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
