In view of the existing servo motor, the servo motor needs to be installed at the corresponding position during normal use. The outer surface of the installed servo motor cannot be fully protected during use. When the outer surface of the servo motor is damaged, it needs to be replaced as a whole. Replacing the entire motor will cause waste of some parts inside the motor. The end of the connecting block is passed through the first clamping block and extended to the side of the second clamping block away from the first clamping block, and then the end of the threaded rod is passed through the connecting block and connected to the first protective shell and the second protective shell respectively, and the threaded rod on the connecting block is rotated in the opposite direction so that the end of the threaded rod is separated from the first protective shell and the second protective shell, and then the connecting block is pulled out of the first clamping block and the second clamping block, so that the first protective shell and the second protective shell can be disassembled and assembled, and finally the position of the servo motor is installed.

[0004] The servo motor is prone to vibration during use, which may affect the performance, accuracy and life of the motor. At the same time, it is inconvenient to ensure its own stability and is prone to displacement or instability due to vibration. Utility Model Content

[0014] Technical effects and advantages of the utility model:

[0015] 1.

[0024] As attached Figure 1-5 The servo motor with multi-structure vibration reduction function shown in the figure comprises a servo motor body 1, and a vibration reduction protection mechanism is arranged on the outer side of the servo motor body 1;

[0025] The vibration reduction protection mechanism includes a protective shell 2, which is arranged on the outside of the servo motor body 1. Threaded holes 3 are opened on both side surfaces of the protective shell 2. A threaded rod 4 is threadedly connected inside the threaded hole 3. A hollow plywood 5 is arranged at one end of the threaded rod 4. A bearing 6 is installed between the threaded rod 4 and the hollow plywood 5. A connecting slide plate 7 is slidably connected inside the hollow plywood 5. A damping plate 8 is fixedly connected to one side of the connecting slide plate 7. A rubber plate 9 is fixedly connected to the bottom of the inner wall of the hollow plywood 5. A sealing sleeve 10 is fixedly installed on the top of the servo motor body 1. A moving cylinder 11 is slidably connected inside the sealing sleeve 10. A fixed rod 12 is fixedly connected to the top of the inner wall of the sealing sleeve 10. A piston 13 is fixedly connected to the bottom of the fixed rod 12. A connecting plate 14 is fixedly connected between the moving cylinder 11 and the servo motor body 1.

[0026] As attached Figure 1 , 2 As shown in , 3 and 5, one end of the threaded rod 4 is fixedly connected to a rotating disk 15, a vibration isolation gasket 16 is installed between the rotating disk 15 and the protective shell 2, one end of the connecting slide plate 7 passes through the hollow plywood 5 and extends to one side of the hollow plywood 5, the damping plate 8 is made of asphalt, and the cross-sectional shape of the hollow plywood 5 is set to be L-shaped, so as to improve the vibration reduction and buffering effect of the overall structure.

[0027] As attached Figure 1 , 2 As shown in FIG. 4 , heat dissipation holes 17 are provided on both sides of the protective shell 2, and the number of the heat dissipation holes 17 is set to be multiple to facilitate heat dissipation.

[0028] As attached Figure 2-5 As shown, two limit rods 18 are fixedly connected to the inner wall of the protective shell 2, and the outer sides of the two limit rods 18 are slidably connected to limit sleeves 19. The top of the limit sleeve 19 is fixedly connected to the bottom of the hollow splint 5, thereby improving the stability of the hollow splint 5 fixing the servo motor body 1 and preventing the hollow splint 5 from rotating due to the vibration of the servo motor body 1.

[0029] As attached Figure 1 , 2As shown in FIGS. 4 and 5 , the bottom of the sealing sleeve 10 passes through the protective shell 2 and extends to the inside of the protective shell 2 , and the piston 13 is slidably connected to the inner wall of the moving cylinder 11 , so as to compress the air inside the moving cylinder 11 and perform buffering and vibration reduction through the high-pressure air caused by vibration.

[0031] Working principle of the utility model: during the use of the servo motor with multi-structure vibration reduction function provided by the utility model, the servo motor body 1 generates vibration during operation. First, the damping plates 8 on both sides of the servo motor body 1 and the rubber plate 9 at the bottom of the servo motor body 1 are used for buffering and vibration reduction, so as to achieve the vibration reduction and protection effect on the servo motor body 1. At the same time, the connecting slide plate 7 slides toward the inside of the hollow splint 5 due to the vibration of the servo motor body 1, and then the connecting slide plate 7 squeezes the polymer buffer pad 20, and further buffers and reduces vibration through the polymer buffer pad 20. At the same time, the servo motor body 1 will drive the connecting plate 14 and the moving cylinder 11 to vibrate, so that the moving cylinder 11 moves inside the sealing sleeve 10. At the same time, due to the fixed position of the fixing rod 12 and the piston 13, the air inside the moving cylinder 11 is compressed, and the vibration of the servo motor body 1 is buffered and reduced by the high-pressure air. At the same time, by rotating the rotating disk 15, the two hollow splints 5 clamp and fix the servo motor body 1 to further ensure the fixing effect of the servo motor body 1, thereby improving the vibration reduction effect.
