Since the surface of the gear 1 305 is engaged with the tooth surface of one of the tooth plates 1 2, the gear 1 305 will translate along the tooth surface of the tooth plate 1 2 when it rotates. When the gear 1 305 moves, it drives the connecting shaft 2 307 connected thereto to move, and the movement of the connecting shaft 2 307 drives the gear 2 connected thereto to rotate. 308 moves, and the gear 2 308 engages with the tooth surface of another gear plate 1 2 to make the movement more stable.

The rotation of the connecting shaft 2 307 drives the cylindrical brush 309 mounted on its surface to rotate.

[0031] In one embodiment, the moving component 4 includes two connecting blocks 401, wherein a forward and reverse motor 3 402 is fixedly installed at the bottom of one end of one connecting block 401, and the output end of the forward and reverse motor 3 402 is fixedly connected to a threaded rod 403 on the surface of the corresponding connecting block 401 through a bearing, and a connecting rod 404 is threadedly sleeved on the surface of the threaded rod 403, and both ends of the surface of one side of the connecting rod 404 are fixedly connected to a support seat 2 405, and the tops of the two support seats 2 405 are fixedly installed with a tooth plate 2 406, and the opposite sides of the two tooth plates 2 406 are fixedly connected with a T-shaped limit block 2 407, and one end of the two tooth plates 2 406 is fixedly installed with a stop block 2 408, and one end of the connecting rod 404 is movably embedded with a limit column 409.

The output end of the forward and reverse motor three 402 rotates to drive the threaded rod 403 connected thereto to rotate, and the rotation of the threaded rod 403 drives the connecting rod 404 connected thereto to move downward, while the limit column 409 embedded at the other end maintains the limit. When the limit column 409 moves downward, it drives the two support seats two 405 to move downward together, and the two support seats two 405 move downward and drive the two tooth plates two 406 to move downward. At this time, since the two limit splints 301 are mounted on the surfaces of the two T-shaped limit blocks two 407, when the two tooth plates two 406 move downward, they will drive the cleaning assembly 3 to move downward together until the top of the cleaning assembly 3 is lower than the bottom of the processing platform.

[0033] In one embodiment, the two connecting blocks 401 are respectively fixedly connected to the two side surfaces of one end of the CNC machine tool body 1, the bottom of the threaded rod 403 is embedded in the top of one end of one of the connecting blocks 401 through a bearing, the top of the threaded rod 403 is embedded in the bottom of one end of one of the tooth plates 2 through a bearing, the bottom of the limiting column 409 is fixedly embedded in the top of one end of the other connecting block 401, and the top of the threaded rod 403 is fixedly embedded in the bottom of one end of the other tooth plate 2.

[0035] In one embodiment, one end of the two tooth plates 1 2 is flush with one end of the two tooth plates 2 406 , and one end of the two T-shaped limit blocks 1 201 is flush with one end of the two T-shaped limit blocks 2 407 .

[0036] Specifically: by making one end of the two tooth plates 1 2 fit flush with one end of the two tooth plates 2 406 respectively, and making one end of the two T-shaped limit blocks 1 201 fit flush with one end of the two T-shaped limit blocks 2 407 respectively, gear 1 305 and gear 2 308 will not be hindered when moving.

[0037] In one embodiment, the two tooth plates 1 2 and the two tooth plates 2 406 are fitted together as a group, the two T-shaped limit blocks 1 201 and the two T-shaped limit blocks 2 407 are fitted together as a group, the two limit clamps 301 are correspondingly movably sleeved on the surfaces of the two groups of T-shaped limit blocks 1 201 and T-shaped limit blocks 2 407, and the gear 1 305 and the gear 2 308 are correspondingly meshed and connected on the surfaces of the two groups of tooth plates 1 2 and tooth plates 2 406.

[0038] Specifically: two T-shaped limit blocks 201 and T-shaped limit blocks 2 407 are respectively located on both sides of the CNC machine tool body 1, and the two limit clamps 301 are respectively limited by the T-shaped limit blocks 201 and T-shaped limit blocks 2 407 on both sides. By meshing the surfaces of gear 1 305 and gear 2 308 with the surfaces of two tooth plates 1 2 and tooth plate 2 406 respectively, the cleaning component 3 can move simultaneously during rotation.

[0039] Working principle: The device is connected to an external power supply through a circuit and started by an external controller. When the parts are processed by a CNC machine tool and the processing platform needs to be cleaned, the forward and reverse motor 1 303 and the forward and reverse motor 2 306 can be started by the external controller. The output end of the forward and reverse motor 1 303 rotates to drive the connecting shaft 1 304 connected to it to rotate. The rotation of the connecting shaft 1 304 drives the gear 1 305 mounted on its surface to rotate. Since the surface of the gear 1 305 is engaged with the tooth surface of one of the tooth plates 1 2, the gear 1 305 will translate along the tooth surface of the tooth plate 2 when it rotates. When the gear 1 305 moves The second connecting shaft 307 is driven to move, and the movement of the second connecting shaft 307 drives the second gear 308 connected to it to move, and the movement is made more stable by the engagement of the tooth surface of another tooth plate 1 2 by the second gear 308. When the second connecting shaft 307 moves, the output end of the second forward and reverse motor 306 rotates, driving the second connecting shaft 307 to rotate. The rotation of the second connecting shaft 307 drives the cylindrical brush 309 on its surface to rotate. At this time, the debris on the top processing platform of the CNC machine tool body 1 can be scraped and cleaned by the brush on the surface of the cylindrical brush 309 until the debris falls to the collection area pushed by the cylindrical brush 309. The inside of the box 104 is collected. In this way, the surface of the platform can be quickly kept clean after each processing is completed, without affecting the next processing. After the cleaning component 3 is cleaned, the forward and reverse motor 1 303 can be reversed by the external controller to move it in the opposite direction until the surfaces of the gear 1 305 and the gear 2 308 are disengaged from the meshing with the two tooth plates 1 2 and are engaged with the surfaces of the two tooth plates 2 406. Then, the forward and reverse motor 3 402 is started by the external controller, and the output end of the forward and reverse motor 3 402 rotates to drive the threaded rod 403 connected thereto to rotate, and the threaded rod 403 rotates with The connecting rod 404 connected to it is moved horizontally downward, and the limiting column 409 embedded at the other end is used to maintain the limit. When the limiting column 409 moves downward, it drives the two support seats 405 to move downward together. The two support seats 405 move downward and drive the two tooth plates 406 to move downward. At this time, since the two limiting splints 301 are sleeved on the surfaces of the two T-shaped limiting blocks 407, the cleaning assembly 3 will be driven downward when the two tooth plates 406 move downward until the top of the cleaning assembly 3 is lower than the bottom of the processing platform. In this way, the debris can be freely stored after each cleaning is completed, and the use of the processing platform will not be affected.
