[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1 to 5 The embodiment of the utility model presented preferably provides a CNC machine tool linear rail assembly, including a slide rail 1 and a slider 2 slidingly arranged on the slide rail 1, the slider 2 is located on both sides of the axial direction of the slide rail 1 and is detachably connected to an adapter 3, and a first clamping member 4 and a second clamping member 5 are rotatably arranged on both sides of the slide rail 1 on the adapter 3, a clamping area is formed between the first clamping member 4 and the second clamping member 5, a cleaning sponge is clamped in the clamping area, and the cleaning sponge abuts against the surface of the slide rail 1, and a limiting member 6 is provided on the adapter 3 which can drive the first clamping member 4 and the second clamping member 5 to maintain a relatively close clamping state.

[0023] Specifically, the cleaning sponge is clamped by the first clamping member and the second clamping member on both sides of the slider, and then limited by the limiting member, so that the cleaning sponge can contact the surface of the slide rail when the slider moves, thereby cleaning the slide rail surface, thereby effectively avoiding the problem of CNC machining debris adhering to the slide rail surface and affecting the normal use of the slider;

[0024] The first clamping member and the second clamping member are mounted on the adapter, and the adapter is detachably mounted on the slider. When the cleaning sponge needs to be disassembled and replaced, the adapter can be directly removed from the slider, which is conducive to recycling and convenient for maintenance and replacement of the cleaning sponge.

[0025] Furthermore, the limiting component 6 includes a tightening screw 61 and a U-shaped limiting frame 62. The U-shaped limiting frame 62 is movably arranged on the adapter 3 and can move axially along the slide rail 1. The first clamping member 4 and the second clamping member 5 are respectively located on the inner side of the U-shaped limiting frame 62, and the inner walls on both sides of the U-shaped limiting frame 62 can respectively movably abut against the relative outer walls of the first clamping member 4 and the second clamping member 5. The tightening screw 61 is threadedly connected to the adapter 3, and one end of the tightening screw 61 is tightly pressed against one side of the U-shaped limiting frame 62, so that the U-shaped limiting frame 62 moves relative to the adapter 3 and remains tightly against the connection state of the first clamping member 4 and the second clamping member 5. Specifically, the tightening screw adopts a machine screw, and the machine screw is screwed forwardly by using an external tool to move the machine screw thread and abut against the U-shaped limit frame, thereby causing the U-shaped limit frame to be displaced relative to the adapter, and then the inner walls on both sides of the U-shaped limit frame respectively abut against the relative outer sides of the first clamping member and the second clamping member, thereby driving the first clamping member and the second clamping member to maintain a relatively close clamping state; conversely, when the cleaning sponge needs to be disassembled, the machine screw is screwed in the reverse direction to disengage the machine screw from the abutment of the U-shaped limit frame, and then the U-shaped limit frame can be displaced and disengaged from the abutment with the first clamping member and the second clamping member, and the first clamping member and the second clamping member are restored to a relatively far apart rotation disassembly state.

[0026] Furthermore, a guide groove 64 is recessed on one side of the adapter 3, a guide hole 65 is provided at one end of the guide groove 64, and a screw hole 66 is provided at the other end of the guide groove 64. A guide rod 67 is provided on one side of the U-shaped limit frame 62, and the guide rod 67 is movably inserted in the guide hole 65. A limiting block 68 is provided on the guide rod 67 in the guide groove 64, and the tightening screw 61 is threadedly inserted in the screw hole 66 and abuts against one end of the guide rod 67.

[0027] Furthermore, the first clamping member 4 and the second clamping member 5 have the same structure, wherein limiting flanges are respectively provided on the opposite inner sides of the first clamping member 4 and the second clamping member 5. The limiting flanges can better wrap and clamp the cleaning sponge.

[0028] Furthermore, the adapter 3 includes a U-shaped connector 31 and a clamping block 32 rotatably disposed on one side of the U-shaped connector 31. The slider 2 is located inside the U-shaped connector 31. A clamping slot 33 capable of being embedded and engaged with the clamping block 32 is disposed on one side of the slider 2. An elastic member is disposed between the clamping block 32 and the U-shaped connector 31, and the elastic member is used to maintain the clamping block 32 in a connected state of being embedded and engaged in the clamping slot 33. Specifically, the elastic member cooperates with the clamping block so that one end of the clamping block can remain elastically engaged in the clamping slot of the slider, thereby achieving an installed connection between the U-shaped connector and the slider. When disassembly is required, it is only necessary to press the other end of the clamping block to flip the clamping block out of the clamping slot, making installation and disassembly convenient.

[0029] Furthermore, the elastic member is a spring or a torsion spring.

[0030] Furthermore, a mounting hole 34 is provided on the slider 2 .
