[0002] A servo synchronous permanent magnet motor is a high-performance electric motor that combines servo system and permanent magnet synchronous motor technology. It is widely used in applications requiring high precision and high dynamic response, such as industrial automation, robotics, and high-end machinery. To regulate the torque of a servo synchronous permanent magnet motor, a frequency converter is typically installed on the motor.

[0003] Since the servo synchronous permanent magnet motor will be connected to different devices during use, and the safety radius of the connected devices is different, the required inverter position should be adaptively adjusted. However, the current inverter is generally directly threaded on the servo synchronous permanent magnet motor, and the operation button is set on the surface of the inverter. When operating, it can only be close to the servo synchronous permanent magnet motor. Therefore, when the inverter position needs to be adjusted, the inverter will not be able to make adaptive adjustments.

[0004] Therefore, it is necessary to design a torque adjustment device for a servo synchronous permanent magnet motor to solve the above problems. Utility Model Content

[0008] Preferably, the block is L-shaped, and the horizontal end of the block is threadedly sleeved on the outer surface of the threaded rod, and one side of the horizontal end of the block is in contact with one side of the inverter, and the vertical end of the block is located on one side of the terminal post, and the bottom of the vertical end of the block is located above the outer side of the terminal post.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0018] Obviously, many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] See also Figure 1-3The utility model provides a torque adjustment device for a servo synchronous permanent magnet motor, comprising a frequency converter 1, wherein a second fixed block 10 is fixedly connected to the bottom of one end of the frequency converter 1, and two symmetrical sliding slots 14 are provided at the bottom of the second fixed block 10, wherein a slider 23 is slidably connected to the inside of the two sliding slots 14, and the bottoms of the two sliders 23 are rotatably connected to a third rotating shaft 22, and the bottoms of the two third rotating shafts 22 are rotatably connected to a rotating block 21, and one end of the two rotating blocks 21 is rotatably plugged with a first rotating shaft 16, and the two first rotating shafts 16 are rotatably connected to a connecting block 12, and the two first rotating shafts 1 6 are fixedly sleeved with gears 17, and the two gears 17 are meshed with each other, the top of the connecting block 12 is fixedly connected to the micro motor 11, and the top of one of the first rotating shafts 16 is fixedly connected to the output shaft of the micro motor 11, and the bottom of the connecting block 12 is fixedly connected to the device box 8, a terminal post 7 is provided on one side of the inverter 1, and a plurality of connecting wires 13 are connected to the terminal post 7, the inner cavity of the device box 8 is rotatably connected to the second rotating shaft 20, and the outer surface of the second rotating shaft 20 is fixedly sleeved with a winding wheel 18, and both ends of the first rotating shaft 16 are provided with a spiral torsion spring 19, and the plurality of connecting wires 13 are rotatably sleeved on the winding wheel 1 8, and one end of the multiple connecting wires 13 passes through the outside of one side of the device box 8. The bottom of the device box 8 is fixed with a connecting plate 9. The inverter 1 can be installed on the servo synchronous permanent magnet motor to be controlled by the connecting plate 9, and connected to the servo synchronous permanent magnet motor through multiple connecting wires 13. The other ends of the multiple connecting wires 13 are connected to the terminal post 7, and the middle length of the multiple connecting wires 13 is wound around the winding wheel 18. When the position of the inverter 1 needs to be adjusted, the micro motor 11 can be turned on and the two gears 17 are engaged to make the two first rotating shafts 16 rotate in the opposite direction, and the two third rotating blocks 21 are driven by the reverse rotation. The shaft 22 and the two sliders 23 slide at the bottom of the second fixed block 10, thereby pushing the second fixed block 10 and the inverter 1 to slide to one side of the connecting plate 9, so that the inverter 1 is distanced from the servo synchronous permanent magnet motor. At the same time, the terminal post 7 will pull the multiple connecting wires 13 to rotate on the winding wheel 18, so that the lengths of the multiple connecting wires 13 can adapt to the distance adjustment of the inverter 1.
