Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the specification drawings and specific implementation manners.

[0021] Referring to Figure 1 - Figure 2 , a numerical control machine tool for precision parts processing includes a control panel 1. The periphery of the front end of the control panel 1 is fixedly connected with an installation frame 2. The installation frame 2 is sleeved outside the control panel 1. One side inside the installation frame 2 is rotatably installed with a connecting shaft 11. A transparent rubber curtain 3 is wound around the connecting shaft 11. Moving grooves 7 for the transparent rubber curtain 3 to move are provided on both the top wall and the bottom wall of the installation frame 2. One end of the transparent rubber curtain 3 away from the connecting shaft 11 is fixedly connected with a push plate 5. A receiving groove 4 for the push plate 5 to be received is provided on the side wall of the installation frame 2 close to the connecting shaft 11, and a connecting groove 8 is provided on the side wall of the installation frame 2 away from the connecting shaft 11. When the transparent rubber curtain 3 is retracted, the push plate 5 will be embedded in the receiving groove 4 and flush with the side surface of the installation frame 2. A locking assembly for fixing the push plate 5 is provided in the connecting groove 8. A cleaning assembly for cleaning the surface of the transparent rubber curtain 3 received in the connecting shaft 11 is provided at the bottom of one side of the installation frame 2 close to the connecting shaft 11. By pulling the push plate 5, the transparent rubber curtain 3 is moved along the moving groove 7 inside the installation frame 2 to cover the control panel 1, and the push plate 5 pulled to the other side of the installation frame 2 is locked through the locking assembly, so as to protect the control panel 1 and prevent accidental touch of the buttons on the control panel 1.

[0022] Referring to Figure 3, the locking assembly includes an L-shaped fixing block 14. A pressing plate 6 is slidably arranged through the mounting frame 2. A spring 13 is fixedly connected between the pressing plate 6 and the inner wall of the mounting frame 2. The L-shaped fixing block 14 is fixedly connected to the side of the pressing plate 6 facing the connecting groove 8. A fixing groove 15 adapted to the vertical end of the L-shaped fixing block 14 is formed on the side of the pushing plate 5 facing the transparent rubber curtain 3. By pulling, the pushing plate 5 is pulled into the connecting groove 8. Due to the movement of the pushing plate 5, one end of the pushing plate 5 presses the L-shaped fixing block 14 to move inward. During the movement, the pressing plate 6 compresses the spring 13 downward. When one end of the L-shaped fixing block 14 is inserted into the fixing groove 15 of the pushing plate 5, the fixing of the transparent rubber curtain 3 is realized. When it is necessary to recycle the transparent rubber curtain 3, just press down the pressing plate 6 to make the L-shaped fixing block 14 disengage from the fixing groove 15 on the pushing plate 5.

[0023] Refer to Figure 3 , the corners of the side of the L-shaped fixing block 14 adjacent to the pushing plate 5 are all arc angles, which is convenient for the pushing plate 5 and the L-shaped fixing block 14 to be lowered, and it is easy to press down the L-shaped fixing block 14.

[0024] Refer to Figure 4 , the cleaning assembly includes two cleaning cotton swabs 10. Rotating shafts 19 are rotatably connected to both sides of the mounting cavity 12 where the transparent rubber curtain 3 is located. Each cleaning cotton swab 10 is fixedly sleeved on the rotating shaft 19, and the cleaning cotton swabs 10 on both sides are in contact with both sides of the transparent rubber curtain 3. When the transparent rubber curtain 3 is retracted and wound around the connecting shaft 11, the two sides of the transparent rubber curtain 3 are cleaned by the cleaning cotton swabs 10 on both sides, improving the cleanliness of the transparent rubber curtain 3.

[0025] Refer to Figure 4 , at the bottom of each rotating shaft 19, a gear 18 is fixedly connected, and the two gears 18 are meshed. A rotating rod 9 fixedly connected to one of the gears 18 is rotatably arranged at the bottom of the mounting frame 2. When the cleaning cotton swabs 10 are used for a period of time, by rotating the rotating rod 9, the two gears 18 mesh and rotate to replace the cleaning surfaces of the cleaning cotton swabs 10, improving the cleaning effect.

[0026] Refer to Figure 4 , a one-way bearing 17 is fixedly connected to the bottom of the connecting shaft 11. A motor 16 is arranged in the mounting frame 2. The outer side of the one-way bearing 17 is connected to the connecting shaft 11, and the inner side of the one-way bearing 17 is connected to the output shaft of the motor 16. When the transparent rubber curtain 3 is pulled by the pushing plate 5, the connecting shaft 11 and the one-way bearing 17 rotate synchronously, facilitating the covering of the transparent rubber curtain 3 outside the control panel 1. When the transparent rubber curtain 3 is retracted, the one-way bearing and the connecting shaft 11 rotate synchronously by the rotation of the motor 16, and the transparent rubber curtain 3 is retracted and wound around the connecting shaft 11.

[0027] Working principle:

[0028] First, pull the push plate 5 to move the transparent rubber curtain 3 along the moving groove 7 in the mounting frame 2 to cover the control panel 1, and pull the push plate 5 into the connecting groove 8 by pulling. Due to the movement of the push plate 5, one end of the push plate 5 presses the L-shaped fixing block 14 to move inward. During the movement, the pressing plate 6 compresses the spring 13 downward. When one end of the L-shaped fixing block 14 is inserted into the fixing groove 15 of the push plate 5, the fixing of the transparent rubber curtain 3 is realized. When it is necessary to recycle the transparent rubber curtain 3, just press down the pressing plate 6 to make the L-shaped fixing block 14 disengage from the fixing groove 15 on the push plate 5.
