[0029] Please see Figures 1-4This utility model provides a technical solution: a servo motor vibration reduction structure, including a servo motor 1, with support legs 2 fixedly installed on the front and rear sides of the bottom of the servo motor 1, a base plate 3 provided below the bottom of the servo motor 1, a slide rail 6 provided on the top of the base plate 3, a threaded rod 12 rotatably installed inside the slide rail 6, and symmetrically distributed left-hand threads and right-hand threads provided on the outer wall of the threaded rod 12.

[0030] The outer wall of the threaded rod 12 is fitted with symmetrically distributed adjustment blocks 8, and the adjustment blocks 8 are slidably installed on the slide rail 6. The top of each of the two adjustment blocks 8 is fixedly installed with a clamping plate 10, and the opposite sides of the two clamping plates 10 are fixedly installed with silicone bushings 11. A groove 14 is opened on one side of the top of the substrate 3, and a control box 7 is fixedly installed on one side of the top of the substrate 3.

[0031] A worm gear 13 is rotatably mounted inside the control box 7, and the bottom end of the worm gear 13 extends into the interior of the groove 14 and is rotatably connected to a bearing mounted on the bottom of the inner wall of the groove 14. The top end of the worm gear 13 passes through the control box 7 and extends to the top of the control box 7. A knob 9 is provided at the top end of the worm gear 13. A worm wheel 15 is fixedly mounted on the outer wall of one end of the threaded rod 12, and the worm wheel 15 meshes with the worm gear 13.

[0032] In this example, the top of the worm gear 13 is provided with a fixed groove 17, the bottom of the knob 9 is fixedly installed with a movable column 16, and the movable column 16 is slidably inserted into the fixed groove 17. Both sides of the inner wall of the fixed groove 17 are provided with sliding grooves 23. A limit rod 20 is fixedly installed inside the sliding groove 23. A slider 21 is sleeved on the outer wall of the limit rod 20, and the slider 21 is slidably installed on the sliding groove 23. The slider 21 is fixedly connected to the lower side of the outer wall of the movable column 16. A spring 18 is sleeved on the outer wall of the limit rod 20 at the top of the slider 21. A positioning rod 19 is fixedly installed on one side of the bottom of the knob 9. The top of the control box 7 is provided with several positioning grooves 22 corresponding to the positions of the positioning rods 19, and the positioning grooves 22 are engaged with the positioning rods 19.

[0033] In this example, both ends of the base plate 3 are fixedly mounted with symmetrically distributed fixing blocks 4. The fixing blocks 4 have mounting holes and rubber shock-absorbing pads 5 are provided at the bottom of the fixing blocks 4 to buffer vibration, reduce the impact on the table surface, and improve the stability of the device.

[0034] In this example, the adjusting block 8 has a T-shaped structure and is adapted to the slide 6. This prevents the adjusting block 8 from coming off the slide 6 and ensures that it slides stably within the slide 6, making the clamping plate 10 move more smoothly.

[0035] In this example, the adjusting block 8 has a threaded hole that matches the threaded rod 12, and the adjusting block 8 is threadedly connected to the threaded rod 12 through the threaded hole.

[0036] In this example, the slider 21 has a sliding hole that matches the limiting rod 20, and the slider 21 is slidably connected to the limiting rod 20 through the sliding hole.

[0037] Working principle: According to Figures 1-4 As shown, all parts of the device not shown are the same as or can be implemented using existing technology. When using this device, the base plate 3 is first securely fixed to the table surface using the cooperation of the fixing block 4 and bolts. Then, the servo motor 1 is precisely placed in the center above the base plate 3, positioned between the two clamping plates 10. Simultaneously, the support leg 2 is connected and fixed to the table surface using bolts. Afterwards, rotating the knob 9 drives the worm gear 13 to rotate. Through the meshing transmission between the worm gear 13 and the worm wheel 15, the worm wheel 15 drives the threaded rod 12 to rotate. Based on the thread transmission characteristics of the left-hand and right-hand threads on the threaded rod 12, and the sliding relationship of the adjusting block 8 within the slide rail 6, the synchronous relative movement or opposite movement of the two slide rails 6 is achieved. The movement of the adjusting block 8 causes the clamping plate 10 and the silicone bushing 11 to move synchronously. When the two adjusting blocks 8 move relative to each other, the two clamping plates 10 drive the silicone bushing 11 to clamp the two sides of the servo motor 1, and the upper end of the clamping plate 10 is fastened into the groove on the top side of the servo motor 1. This clamping and fixing method significantly improves the stability of the servo motor 1 during operation. When the servo motor 1 is running, the vibration it generates will cause instability and jumping. At this time, the jumping and swinging force generated by the vibration is transmitted to the silicone bushing 11. The silicone bushing 11 absorbs most of the vibration energy with its own elasticity and flexibility, effectively buffering the vibration of the servo motor 1, thereby achieving a vibration reduction effect. When it is necessary to disassemble, repair and maintain the servo motor 1, simply operate the knob 9 to move the two clamping plates 10 in opposite directions to release the clamping and fixing of the servo motor 1, and then remove the connecting bolts between the servo motor 1 and the table to complete the disassembly. There is no need to remove the base plate 3. Since the opposite movement of the two clamping plates 10 on the substrate 3 will not hinder the disassembly and assembly of the servo motor 1, the ease of use of the device is greatly improved, which is conducive to carrying out maintenance and repair work efficiently in practical applications.

[0038] according to Figures 1-4As shown, when controlling the position of the clamping plate 10 using the knob 9, an upward pulling force must first be applied to the knob 9. The displacement of the knob 9 causes the movable column 16 to slide within the fixed groove 17. Simultaneously, the movement of the movable column 16 drives the slider 21 to slide on the outer wall of the limiting rod 20, and exerts a squeezing effect on the spring 18. As the knob 9 moves upward, the positioning rod 19 disengages from the corresponding positioning groove 22. At this time, the knob 9, having lost the locking and limiting action between the positioning rod 19 and the positioning groove 22, can rotate freely, thereby achieving the adjustment of the position of the clamping plate 10. After the position of the clamping plate 10 is determined, the vertical limiting action on the knob 9 is released. Under the elastic restoring force of the spring 18, the slider 21 and the movable column 16 drive the knob 9 to return downward, causing the positioning rod 19 to engage with the corresponding positioning groove 22, thus achieving the self-locking function of the knob 9 rotating in the horizontal direction. In addition, by combining the self-locking characteristics of the worm gear 13 and worm wheel 15, a double locking effect is achieved on the clamping plate 10, which effectively enhances the stability and reliability of the clamping plate 10 in the process of clamping and fixing the servo motor 1.

[0039] It is worth noting that this vibration damping structure has a flexible installation method, and multiple sets can be installed on the same servo motor, thereby further enhancing the fixing and vibration damping effect of the servo motor.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
