[0002] A ball screw is a transmission element that converts rotary motion into linear motion, or converts linear motion into rotary motion. It mainly realizes the conversion of rotational motion into linear motion, or converts torque into axial repetitive force. Ball screws have the characteristics of high precision, reversibility and high efficiency, so they are most commonly used in tool machinery and precision machinery.

These pollutants will affect the smooth rolling of the ball and thus affect the normal operation of the screw. Currently, operators manually wipe the surface of the screw to keep it clean, but manual cleaning is not only time-consuming and labor-intensive, but also leads to further increase in labor costs in production.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1-Figure 5 As shown, the utility model provides a precision ball screw, including a screw body 1, the outer wall of the screw body 1 is threadedly connected with a mounting sleeve 2, the inner wall of the mounting sleeve 2 is provided with a slide groove 3, the inner wall of the slide groove 3 is provided with a group of ball bodies 4, the top of the mounting sleeve 2 is fixedly installed with a mounting seat 5, the top of the mounting seat 5 is provided with two mounting grooves 6, one side of the inner wall of the two mounting grooves 6 is provided with a square hole 7, the top of the mounting seat 5 is in contact with two mounting seats 2 8, the top of the two mounting seats 2 8 is provided with a square hole 2 9, the inner wall of the two mounting seats 2 8 is provided with a mounting groove 2 10, the inner wall of the two mounting grooves 2 10 is fixedly inserted with a cleaning brush 11, and the outer walls of the two cleaning brushes 11 are in contact with the outer wall of the screw body 1, and the outer walls of the two mounting seats 2 8 are provided with a group of mounting grooves 3 12.

[0025] The effect achieved by the entire embodiment 1 is that when the screw body 1 is driven to rotate by the motor, a group of ball bodies 4 will slide inside the slide groove 3. The sliding of the group of ball bodies 4 will drive the mounting sleeve 2 to move up and down on the surface of the screw body 1. The mounting sleeve 2 makes the top mounting seat 1 5 and the mounting seat 2 8 rise and fall together. The mounting seat 2 8 will drive the cleaning brush 11 to move up and down to remove oil, dust and other pollutants on the surface of the screw body 1, thereby improving its movement accuracy and efficiency. Automatic cleaning can also effectively reduce cleaning costs.

[0026] Embodiment 2, as Figure 2-Figure 5As shown, the inner wall of one of the two groups of mounting grooves 3 12 is fixedly inserted with a group of positioning rods 13, and the inner wall of the other group of the two groups of mounting grooves 3 12 is movably inserted with the outer wall of the group of positioning rods 13, the inner walls of the two square holes 2 9 are movably inserted with a clamping block 14, and the outer side of the two clamping blocks 14 is provided with a mounting groove 4 15, and the inner wall of the two mounting grooves 4 15 is fixedly installed with a group of springs 16, and the outer walls of the two groups of springs 16 are fixedly installed between them. There is a clamping block 17, and the inner walls of the two square holes 7 are movably inserted with the outer walls of the clamping block 17, the inner walls of the two mounting grooves 6 are movably inserted with the clamping block 17, a group of springs 18 are fixedly installed on the tops of the two clamping blocks 14, a group of fixing plates 19 are fixedly installed on the tops of the two groups of springs 18, and the inner walls of the two square holes 9 are fixedly inserted with the outer walls of a group of fixing plates 19, and the tops of the two clamping blocks 14 are fixedly installed with extrusion plates 20.

[0027] The effect achieved by the entire embodiment 2 is that when the operator needs to replace the cleaning brush 11, he can press the block 2 17, and the block 2 17 will then compress a group of springs 16 into the inside of the mounting groove 4 15, and a group of springs 2 18 will pull the block 14 into the square hole 17. Then the operator only needs to pull out a group of positioning rods 13 fixed on one mounting seat 2 8 from a group of mounting grooves 3 12 opened on another mounting seat 2 8, and then the two mounting seats 2 8 can be removed, thereby preventing the cleaning brush 11 from being used for too long and affecting the cleaning effect.

[0028] Working principle: When the screw body 1 starts to rotate under the action of external force, the screw body 1 will drive a group of ball bodies 4 in contact with it to start moving continuously inside the slide groove 3. When a group of ball bodies 4 move, they will drive the mounting sleeve 2 to move up and down on the surface of the screw body 1. When the mounting sleeve 2 moves, it will drive the top mounting seat 1 5 to move together. The mounting seat 1 5 will make the mounting seat 2 8 move together. The mounting seat 2 8 will make the cleaning brush 11 on the inner wall move together to remove the pollutants on the surface of the screw body 1. When the cleaning brush 11 is used for too long , causing the surface to be contaminated with more pollutants, the operator can press the block 2 17 to squeeze a group of springs 16 and retract them into the installation groove 4 15. At this time, the stretched group of springs 2 18 will pull the block 14 upward to prevent the block 2 17 from entering the square hole 7 again. Then the operator only needs to pull the two mounting seats 2 8 outward to pull a group of positioning rods 13 inside one mounting seat 2 8 out from a group of mounting grooves 3 12, thereby separating the two mounting seats 2 8 and replacing the contaminated cleaning brush 11.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
