They integrate advanced technologies such as precision machinery, computer technology, electronic technology, servo drive, sensors, and automatic control, and can efficiently and accurately complete the processing tasks of various complex parts. CNC machine tools control the movement of each axis of the machine tool according to a predetermined trajectory by inputting specific program codes, thereby achieving precise processing of workpieces.

The CNC machine tool with a chip removal and cleaning structure, through the setting of a waste liquid collector, guides and transports the cutting fluid containing iron chips during the cutting process, discharges it into the filter for double filtration, and then uses the setting of the waste chip remover to scrape the filtered iron chips and absorb the scraped iron chips for subsequent disassembly and cleaning, and cooperates with the liquid collecting box to centrally contain the cutting fluid with iron chips filtered out, thereby improving the utilization efficiency of the CNC machine tool and the cleaning and recovery effect of the cutting fluid.

The left and right sides of the multiple U-shaped frames 321 are fixedly connected with inverted L-shaped connecting short rods 325. The tops of the multiple sets of inverted L-shaped connecting short rods 325 extend to the bottom of the L-shaped connecting plate 3115 through the L-shaped connecting plate through groove 3116 and are fixedly connected to inverted L-shaped connecting rods 326 on the outside. The tops of the multiple sets of inverted L-shaped connecting rods 326 extend to the top of the adsorption plate 3117 and are fixedly connected to the inside with clamps 327. The bottoms of the multiple clamps 327 are respectively attached to the top sides of the filter screen 3118. The bottoms of the multiple air extraction plates 324 are fixedly connected with pipes 329.The debris collection mechanism 4 includes an air extraction control bin 41, the left and right sides of which are fixedly connected to the inner bottom of the left and right two assembly connecting rods 3114, respectively; the left and right sides of the inner wall of the air extraction control bin 41 are rotatably connected with columnar rotating rods 44, the front and rear ends of the two columnar rotating rods 44 extend to the outer wall of the air extraction control bin 41, the rear ends of the two columnar rotating rods 44 are fixedly connected with worm gears 45, the multiple sides on the left side of the air extraction control bin 41 are respectively fixedly connected to the ends of the multiple pipes 329 away from the air extraction plate 324, the front and rear sides of the bottom of the air extraction control bin 41 are respectively fixedly connected with the air extraction bin slider 43, and the middle part of the bottom of the air extraction control bin 41 is fixedly connected with a control The storage drive block 42, the outer walls of the two worm wheels 45 mesh with the worm 3113, the rear sides of the two worm wheels 45 and the front ends of the two columnar rotating rods 44 are fixedly connected with rotating rods 46, the inclinations of the left and right groups of rotating rods 46 are opposite, the inner sides of the left and right groups of rotating rods 46 away from the worm wheels 45 and the columnar rotating rods 44 are movably connected with lifting cross bars 47, the front and rear sides of the inner sides of the two lifting cross bars 47 are fixedly connected with push-pull vertical rods 48, the inner sides of the left and right groups of push-pull vertical rods 48 are respectively slidably connected to the outer sides of the left and right groups of vertical connecting rods 3114, and the tops of the left and right groups of push-pull vertical rods 48 are fixedly connected with a collection frame 49, and the inner wall of the collection frame 49 is a hollow design;

[0040] When the inner wall of the CNC machine tool 1 is processed and the debris generated by the cutting needs to be collected and cleaned, the crawler motor 314 is first started. After the crawler motor 314 is started, the crawler 316 is driven to rotate through the conveyor disc 315. The crawler 316 rotates while driving the second conveyor disc 317 to rotate. The rotation of the second conveyor disc 317 drives the bidirectional screw rod 319 to rotate. The rotation of the bidirectional screw rod 319 drives the two outermost U-shaped frame transmission blocks 322 to move in opposite directions. The movement of the two U-shaped frame transmission blocks 322 drives the two outermost U-shaped frames 321 to move. The two outermost U-shaped frames 321 The movement drives the multiple U-shaped frames 321 inside to move through the multiple groups of hinged rods 328 connected thereto. During the movement of the multiple U-shaped frames 321, the U-shaped frame sliders 323 at the bottom thereof slide smoothly along the columnar slide bar 3110 to ensure the stability of the movement of the U-shaped frames 321. At the same time, as the U-shaped frames 321 move, the air extraction plates 324, the inverted L-shaped connecting rods 326 and the clamping plates 327 at the top thereof are driven to move together, so that the multiple air extraction plates 324 and the clamping plates 327 are expanded at the bottom of the adsorption plate 3117, thereby increasing the adsorption range, so that the debris can be better adsorbed and clamped on the filter screen 3118;

[0041] At the same time, when the bidirectional screw 319 rotates, the conical teeth 318 at its rear end mesh with the second conical teeth 3112, driving the worm 3113 to rotate synchronously, and the rotation of the worm 3113 further drives the two worm wheels 45 to rotate and then drives the two columnar rotating rods 44 to rotate. Due to the meshing relationship between the worm wheel 45 and the worm 3113, the rotation of the worm wheel 45 and the columnar rotating rod 44 drives the lifting cross bar 47 to lift and lower through the rotating rod 46. The movement of the lifting cross bar 47 is transmitted to the collecting frame 49 through the push-pull vertical rod 48, so that the collecting frame 49 is lifted and lowered in the vertical direction to the top of the adsorption plate 3117. As the collecting frame 49 is lifted and lowered and the size of the collecting frame is larger than the adsorption plate 3117, the drifting range of the debris can be effectively limited. The collecting frame 49 is closer to the processing position, so that the debris is more likely to fall into the collecting frame 49 under the action of gravity, further improving the debris collection effect. At this time, the debris is effectively collected on the filter screen 3118;

[0042] When the above structure is completed, the air extraction control chamber 41 can be started. After the air extraction control chamber 41 is started, the internal air extraction pump starts to work, and air is extracted through the pipe 329 and the air extraction plate 324. Due to the air extraction effect, a negative pressure is formed in the area between the adsorption plate 3117 and the filter screen 3118, so that the debris is adsorbed on the filter screen 3118. At the same time, as the air extraction process continues, the debris is more tightly pressed on the filter screen, reducing the scattering and flying of the debris. During the air extraction process, by adjusting the output power of the air extraction control chamber 41, the air extraction strength can be flexibly controlled to meet the cleaning needs of debris of different sizes and types.

[0043] After the processing is completed, when it is necessary to clean the debris adsorbed on the top of the filter 3118, the crawler motor 314 is started in reverse, and the bidirectional screw rod 319 rotates in the opposite direction, so that each U-shaped frame 321 gathers toward the center along the columnar slide bar 3110, thereby driving the vacuum plate 324, the inverted L-shaped connecting rod 326 and the clamping plate 327 to move together, thereby reducing the distance between the vacuum plate 324 and the clamping plate 327, making it easier to clamp and fix the debris adsorbed on the filter 3118 to prevent the debris from scattering during the cleaning process. At this time, the vacuum control chamber 41 can be stopped and the debris cleaning mechanism 3 and the debris collection mechanism 4 can be transmitted to the outer wall of the CNC machine tool 1 through the conveying plate 2. At this time, the staff can clamp the debris on the filter 3118 and move it to the designated collection container.

[0044] like Fig.10As shown, the conveying plate 2 includes a conveying plate body 21, a motor placement bin 23 is fixedly connected to the middle of the right side of the conveying plate body 21, a plurality of conveying grooves 22 are respectively opened on the top of the conveying plate body 21, a motor 24 is fixedly connected to the inner wall of the motor placement bin 23, an output end of the motor 24 extends to the inner wall of the middle conveying groove 22 and is fixedly connected to a screw rod 25, the left end of the screw rod 25 is rotatably connected to the left side of the inner wall of the middle conveying groove 22, the outer wall of the screw rod 25 is threadedly connected to the inner wall of the control bin transmission block 42, and the inner walls of the front and rear side conveying grooves 22 are respectively slidably connected to the outer walls of the two air extraction bin sliders 43;

[0045] When it is necessary to move the debris cleaning mechanism 3 and the debris collecting mechanism 4 out of the inner wall of the CNC machine tool 1 to collect and process the debris, the motor 24 is started at this time, and the output end of the motor 24 drives the screw rod 25 to rotate. Since the outer wall of the screw rod 25 is threadedly connected to the inner wall of the control bin transmission block 42, as the screw rod 25 rotates, it will drive the control bin transmission block 42 to move along the length direction of the screw rod 25. While the control bin transmission block 42 moves, it drives the exhaust control bin 41, the debris collecting mechanism 4 as a whole, and the debris cleaning mechanism 3. During the movement, the vacuum control chamber 41 moves, and the vacuum chamber slider 43 at the bottom thereof slides smoothly along the transmission grooves 22 on the front and rear sides to ensure the stability of the movement of the vacuum control chamber 41. At the same time, as the vacuum control chamber 41 moves, the vacuum control chamber 41 is connected to the screw rod 25 through the control chamber transmission block 42, so that the vacuum control chamber 41 can move smoothly and accurately, and then the debris cleaning mechanism 3 and the debris collection mechanism 4 are integrally transmitted to the outer wall of the CNC machine tool 1, so that the staff can collect and process the debris conveniently.

[0046] In addition, the present invention also relates to a CNC machine tool with a chip removal and cleaning structure and a method for using the same, comprising the following steps:

[0047] Step 1: The CNC machine tool 1 processes the workpiece, and at the same time, the crawler motor 314 in the debris cleaning mechanism 3 is started to drive the conveyor plate 315 and the crawler 316, thereby driving the bidirectional screw rod 319 and the cleaning assembly 32 to operate, so that the multiple U-shaped frames 321 move and expand;

[0048] Step 2: As the bidirectional screw 319 rotates, the worm 3113 synchronously drives the worm wheel 45 to rotate, and the collection frame 49 is driven to rise and fall to the top of the adsorption plate 3117 through the rotating rod 46 and the lifting cross bar 47 to limit the floating range of the debris, and at the same time, the air extraction control chamber 41 is started to extract air, and the debris generated by cutting is adsorbed onto the filter screen 3118 through the air extraction plate 324 and the pipeline 329;

[0049] Step 3: After the processing is completed, the crawler motor 314 is started in reverse, so that each U-shaped frame 321 gathers toward the center, clamps and fixes the debris adsorbed on the filter screen 3118, and stops the work of the air extraction control chamber 41;

[0050] Step 4: Start the motor 24, and smoothly and accurately transfer the debris cleaning mechanism 3 and the debris collecting mechanism 4 as a whole to the outer wall of the CNC machine tool 1 through the threaded connection between the screw rod 25 and the control bin transmission block 42;

[0051] Step 5: The staff picks up the debris on the filter 3118 and moves it to a designated collection container to complete the cleaning and collection of the debris.

[0052] Working principle of the present invention: when the inner wall of the CNC machine tool 1 is processed and the debris generated by the cutting needs to be collected and cleaned, the crawler motor 314 is first started. After the crawler motor 314 is started, the crawler 316 is driven to rotate through the conveyor disc 315. The crawler 316 rotates while driving the second conveyor disc 317 to rotate. The second conveyor disc 317 rotates and drives the bidirectional screw rod 319 to rotate. The bidirectional screw rod 319 rotates while driving the two outermost U-shaped frame transmission blocks 322 to move in opposite directions. The movement of the two U-shaped frame transmission blocks 322 drives the two outermost U-shaped frames 321 to move. The movement of the two outermost U-shaped frames 321 drives the inner multiple U-shaped frames 321 to move through the multiple sets of hinged rods 328 connected. The multiple U-shaped frames During the movement of 321, the U-shaped frame slider 323 at the bottom thereof slides smoothly along the columnar slide bar 3110 to ensure the stability of the movement of the U-shaped frame 321. At the same time, as the U-shaped frame 321 moves, the air extraction plate 324, the inverted L-shaped connecting rod 326 and the clamping plate 327 at the top thereof are driven to move together, so that the multiple air extraction plates 324 and the clamping plates 327 are expanded at the bottom of the adsorption plate 3117, thereby increasing the adsorption range, so that the debris can be better adsorbed and clamped on the filter screen 3118. At the same time, when the bidirectional screw 319 rotates, the conical teeth 318 at the rear end thereof mesh with the second conical teeth 3112, driving the worm 3113 to rotate synchronously. The rotation of the worm 3113 further drives the two worm wheels 45 to rotate, thereby driving the two columnar rotating rods 44 rotates, and due to the meshing relationship between the worm wheel 45 and the worm 3113, the rotation of the worm wheel 45 and the columnar rotating rod 44 drives the lifting cross bar 47 to perform lifting movement through the rotating rod 46. The movement of the lifting cross bar 47 is transmitted to the collecting frame 49 through the push-pull vertical rod 48, so that the collecting frame 49 is lifted and lowered in the vertical direction to the top of the adsorption plate 3117. As the collecting frame 49 is lifted and lowered and the size of the collecting frame is larger than the adsorption plate 3117, the drifting range of the debris can be effectively limited, and the collecting frame 49 is closer to the processing position, so that the debris can more easily fall into the collecting frame 49 under the action of gravity, further improving the debris collection effect. At this time, the debris is effectively collected on the filter screen 3118. When the above structure is completed, , the air extraction control chamber 41 can be started. After the air extraction control chamber 41 is started, the internal air extraction pump starts to work, and air is extracted through the pipe 329 and the air extraction plate 324. Due to the air extraction effect, a negative pressure is formed in the area between the adsorption plate 3117 and the filter screen 3118, so that the debris is adsorbed on the filter screen 3118. At the same time, as the air extraction process continues, the debris is more tightly compacted on the filter screen, reducing the scattering and flying of the debris. During the air extraction process, by adjusting the output power of the air extraction control chamber 41, the air extraction force can be flexibly controlled to meet the cleaning needs of debris of different sizes and types. After the processing is completed, when the debris adsorbed on the top of the filter screen 3118 needs to be cleaned, the crawler motor 314 is started in reverse at this time, and the bidirectional screw rod 319 rotates in the opposite direction.The U-shaped frames 321 are gathered toward the center along the columnar slide bar 3110, thereby driving the air extraction plate 324, the inverted L-shaped connecting rod 326 and the clamping plate 327 to move together, thereby reducing the distance between the air extraction plate 324 and the clamping plate 327, making it easier to clamp and fix the debris adsorbed on the filter screen 3118 to prevent the debris from scattering during the cleaning process. At this time, the air extraction control chamber 41 can be stopped and the debris cleaning mechanism 3 and the debris collecting mechanism 4 can be transported as a whole to the outer wall of the CNC machine tool 1 through the conveying plate 2. At this time, the staff can pick up the debris on the filter screen 3118 and move it to the designated collection container;

[0053] When it is necessary to move the debris cleaning mechanism 3 and the debris collecting mechanism 4 out of the inner wall of the CNC machine tool 1 to collect and process the debris, the motor 24 is started at this time, and the output end of the motor 24 drives the screw rod 25 to rotate. Since the outer wall of the screw rod 25 is threadedly connected to the inner wall of the control bin transmission block 42, as the screw rod 25 rotates, the control bin transmission block 42 will be driven to move along the length direction of the screw rod 25. While the control bin transmission block 42 moves, it drives the exhaust control bin 41, the debris collecting mechanism 4 as a whole, and the debris cleaning mechanism 3 to move together. During the movement of the exhaust control bin 41, the exhaust bin slider 43 at the bottom thereof slides smoothly along the transmission grooves 22 on the front and rear sides to ensure the stability of the movement of the exhaust control bin 41. At the same time, as the exhaust control bin 41 moves, it is connected to the screw rod 25 through the threaded connection between the control bin transmission block 42 and the screw rod 25, so that the exhaust control bin 41 can move smoothly and accurately, thereby transmitting the debris cleaning mechanism 3 and the debris collecting mechanism 4 as a whole to the outer wall of the CNC machine tool 1.
