[0014] Compared with the prior art, the present utility model provides a guide rail seat for a numerical control machine tool, having the following beneficial effects:

[0015] 1. Through the provided compression cylinder, when the ball slider body moves along the guide rail seat body, it drives the moving plate to move. The moving plate drives the clamping post to move, and the clamping post drives the connecting rope to move back and forth. When the ball slider body moves to one side, the connecting rope moves to the other side. The connecting rope drives the two compression cylinders to move, causing the two compression cylinders to approach the fixed ring and the extrusion ring respectively. The ball slider body drives the support post to move, and the support post drives the extrusion ring to move. The fixed ring in the moving direction of the extrusion ring and the ball slider body squeezes the compression cylinder. At the same time, the connecting rope drives the extrusion block to move, and the other fixed ring of the extrusion block squeezes the compression cylinder, causing the air flow in the compression cylinder to be discharged through the air pipe. The air flow blows through the pipe towards the bellows cover body and blows away the waste chips attached to the top of the bellows cover body, which is beneficial to preventing the waste chips from accumulating on the top of the bellows cover body, resulting in the bellows cover body constantly rubbing and scratching against the waste chips during the stretching and compression processes, causing damage to the surface of the bellows cover body and affecting the working life of the bellows cover body. At the same time, the waste chips accumulated on the top of the bellows cover body collapse, causing the bellows cover body to get stuck on the guide rail seat body or hindering the movement of the ball slider body, affecting the normal operation of the ball slider body.

[0016] 2. Through the provided elastic rope, during the stretching and compression process of the bellows cover body, it drives the elastic rope to continuously expand and contract along the surface of the bellows cover body. The elastic rope drives the fine wool brush on the surface of the elastic rope to continuously move, causing the fine wool brush on the surface of the elastic rope to always fill the bottom of the bellows cover body, which is beneficial to preventing waste chips, etc. from entering the guide rail seat body through the bottom of the bellows cover body during the movement and expansion and contraction of the bellows cover body, resulting in the guide rail seat body and the ball slider body being affected by the scraping and friction of the waste chips, and improving the running stability of the guide rail seat body and the ball slider body.

A first bolt 3 is threadedly connected between the top of the ball screw slider body 2 and the circumferential side surface of the clamping post 5.

[0025] A plug 13 is fixedly connected between both sides of the fixed plate 10. Both ends of the two connecting ropes 6 respectively pass through the plug 13 and are fixedly connected to one end of the clamping post 5. The circumferential side surface of the connecting rope 6 is slidably connected to the inside of the plug 13.

[0026] At least two fixed posts 14 are fixedly connected to both sides of the guide rail seat body 1. A fixed ring 15 aligned with a fixed ring 15 is fixedly connected to one end of the fixed post 14.

[0029] Working principle: When the ball slider body 2 moves along the guide rail seat body 1, it drives the moving plate 4 to move. The moving plate 4 drives the clamping column 5 to move.

The other fixed ring 15 of the extrusion block 23 squeezes the compression cylinder 17, so that the air flow in the compression cylinder 17 is discharged through the air pipe 16. The air flow blows through the pipe 16 to the bellows body 7 and blows away the waste chips attached to the top of the bellows body 7, which is beneficial to preventing the waste chips from accumulating on the top of the bellows body 7, resulting in continuous friction and scratching between the bellows body 7 and the waste chips during the stretching and compression processes, causing damage to the surface of the bellows body 7 and affecting the working life of the bellows body 7. At the same time, the waste chips accumulated on the top of the bellows body 7 collapse, resulting in the bellows body 7 being stuck on the guide rail seat body 1 or hindering the movement of the ball slider body 2, affecting the normal operation of the ball slider body 2.

[0030] During the stretching and compression process of the bellows body 7, it drives the elastic rope 6 to continuously stretch and contract along the surface of the bellows body 7. The elastic rope 6 drives the fine fluff brushes on the surface of the elastic rope 6 to continuously move, so that the fine fluff brushes on the surface of the elastic rope 6 are always filled at the bottom of the bellows body 7, which is beneficial to preventing waste chips, etc. from entering the guide rail seat body 1 through the bottom of the bellows body 7 during the movement and stretching of the bellows body 7, resulting in the guide rail seat body 1 and the ball slider body 2 being affected by the scraping and friction of the waste chips, and improving the running stability of the guide rail seat body 1 and the ball slider body 2.
