[0005] 1. In actual applications, when the cantilever of the cantilever single winch is running at high speed, the two cantilevers will generate huge centrifugal force. Although this centrifugal force can be partially offset by the fixing parts, it will still produce certain vibration and shaking. After running for a long time, it will increase the internal wear and tear of the equipment and shorten its service life. The existing technology has not made improvements to this problem. Therefore, in this case, it cannot meet the needs.

[0006] 2. In actual applications, the operation of the motor will generate vibration, which will be transmitted to the entire equipment, causing noise. It is also more likely to cause vibration displacement of the screws and bolts that fix the motor after long-term operation, thereby causing the bolts to fall off. Although the existing technology provides sound insulation cotton to solve the noise problem, it cannot solve the vibration problem, which will increase the loss of equipment in the long run.

[0007] In view of this, it is necessary to improve the defects in the traditional grinding device. Utility Model Content

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] The working principle of the utility model is as follows Figure 1-Figure 4As shown: A cantilever single twisting machine for cable processing, including a main body 1, the main body 1 is set in a rectangular shape, and a motor slot 2 is opened at the bottom of one side of the rear end, a motor 3 is arranged inside the motor slot 2, and a motor seat 4 is fixedly connected to the bottom end of the motor 3. The bottom end of the motor seat 4 is provided with a structure for providing anti-seismic buffering for the motor 3. The structure includes a fixed block 5 fixed to the four corners of the bottom end of the motor seat 4. At the same time, an insertion shaft 6 is inserted in the fixed block 5, and both ends of the insertion shaft 6 are rotatably connected to a buffer rod 7. The bottom end of the buffer rod 7 is rotatably connected to an insertion shaft 2 8. The insertion shaft 2 8 is located The middle part of the buffer rods 7 on both sides is rotatably connected with a buffer block 9, and a longitudinally arranged buffer shaft 10 is inserted in the buffer block 9. The buffer blocks 9 are interconnected by a spring 11 that is sleeved on the outside of the buffer shaft 10. The front and rear ends of the buffer shaft 10 are fixedly connected with a buffer seat 12, and the buffer seat 12 is fixedly connected to the bottom end of the motor slot 2. The buffer seat 12 and the motor seat 4 are interconnected by a damper 13, and a spring 14 is sleeved on the outside of the damper 13. The top and bottom ends of the spring 14 are fixedly connected to the motor seat 4 and the buffer seat 12 respectively.

[0023] Therefore, when the motor 3 is running and generating vibration, its gravity and vibration force will cause it to move up and down continuously. During the downward pressure, the motor 3 and the motor seat 4 at its bottom will compress the damper 13 and the spring 14. At the same time, the fixed block 5 and the buffer rod 7 connected thereto will squeeze each other inward, making the buffer blocks 9 close to each other and squeezing the spring 2 11. When it moves upward, the effect is opposite, and this process is repeated. The damper 13, spring 14 and spring 2 11 absorb and offset the impact force during their deformation to achieve a shock absorbing effect.

[0024] Finally, a buffer structure 15 for stability is provided on both sides of the bottom end and the front and rear ends of the main body 1. In addition, a cavity 16 is opened inside the main body 1, and a rotating shaft 17 is provided at the upper end of the cavity 16. The front end of the rotating shaft 17 is fixedly connected to a cantilever frame 18, and the upper and lower parts of the front end of the cantilever frame 18 are provided with cantilevers 26. The output shaft of the motor 3 and the rotating shaft 17 are connected to each other through a belt 19.

[0025] The above-mentioned components together constitute the general appearance structure of the cantilever single twisting machine for cable processing of the utility model.

[0026] In order to further demonstrate the specific working principle of the cantilever single twisting machine for cable processing of the utility model, the above-mentioned buffer structure 15 includes an outer box 20 arranged at the bottom end of the main body 1, an inner box 21 is arranged inside the outer box 20, and the front and rear steps on both sides of the bottom end of the main body 1 are fixedly connected with a pressure rod 22, the pressure rod 22 passes through the outer box 20 and the inner box 21 and extends to the inside of the inner box 21, and the bottom end of the pressure rod 22 and the bottom end of the inner wall of the inner box 21 are connected to each other through a damper 23, and the outer part of the damper 23 is sleeved with a spring 3 27, and the top and bottom ends of the spring 3 27 are respectively fixedly connected to the pressure rod 22 and the inner box 21. The front and rear ends of the outer wall of the inner box 21 are inserted with an air pipe 24, and the bottom end of the outer box 20 is fixedly connected with a suction cup 25, and the air pipe 24 passes through the outer box 20 and extends to the inside of the suction cup 25.

[0027] The technical effect achieved by the technical solution composed of the above-mentioned technical features is: when the pressure rod 22 is pressed down, it will drive the damper 23 and the spring 3 27 to contract. Since the pressure rod 22 divides the internal space of the inner box 21 into two parts, and the contact surface between the pressure rod 22 and the inner box 21 is sealed, when it compresses the lower end space of the inner box 21, it will simultaneously cause the part of the air in the inner box 21 located below the pressure rod 22 to be compressed, and the air above will be diluted. This results in the need to keep the internal pressure of the inner box 21 consistent. Therefore, its upper part will absorb air into the suction cup 25 through the air pipe 24 until the air pressure above and below the pressure rod 22 in the inner box 21 is consistent. At this time, the air in the suction cup 25 becomes sparse, and under the action of atmospheric pressure, the suction cup 25 is pressed tightly against the bottom surface, which makes the entire device more stable and can offset the vibration caused by the centrifugal force of the suspension rotation to a certain extent.

[0028] It should be specially noted here that the components described and identified in the text and drawings of the utility model are the key components constituting the utility model, and the remaining non-key components or obvious prior art components, as well as technical features similar to the prior art, are not shown. However, this does not mean that the above-mentioned components do not exist in the utility model, nor can it be interpreted as a practical limitation on the utility model.

[0029] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
