[0002] CNC grinding machine is a machine tool that uses grinding tools to grind the surface of workpieces through CNC technology. It is the product of the combination of information technology and mechanical manufacturing technology, and represents the technical level and development trend of modern basic machinery. Most grinding machines use high-speed rotating grinding wheels for grinding, and a few use other grinding tools such as oilstones and abrasive belts and free abrasives for processing, such as honing machines, superfinishing machines, grinders and polishing machines. Grinding machines can process materials with higher hardness, such as hardened steel, cemented carbide, etc., and can also process brittle materials, such as glass and granite. Grinding machines can perform high-precision grinding with very small surface roughness, and can also perform high-efficiency grinding, such as strong grinding, etc.

[0033] The driving assembly 5 includes a driving motor 501 , a gear 502 is fixedly mounted on the output end of the driving motor 501 , a ring member 503 is movably connected to one side of the gear 502 , and a first rectangular rod 504 is fixedly mounted on one side of the top of the ring member 503 .

[0034] The above scheme is adopted: through the cooperation of the movable unit 4 and the driving assembly 5, the gear 502 drives the ring member 503 to rotate, and the rotation of the ring member 503 drives the movable rod 407 to move. When the movable rod 407 moves toward the rectangular plate 9 to resist the movable plate 402, the movable plate 402 moves upward, so that the first spring telescopic rod 403, the bellows 405 and the second spring telescopic rod 404 are contracted, so that the gas in the bellows 405 blows the debris on the surface of the steel plate, so that some easy-to-fall debris falls from the surface of the steel plate, and the ring member 503 drives the first rectangular rod 504 to move to resist the second rectangular rod 505, so that the second rectangular rod 505 drives the connecting plate 506 to flip downward, and the larger debris generated by grinding falls quickly, so that the debris generated by grinding is quickly cleaned up, thereby avoiding consuming a lot of time for cleaning the debris, improving the grinding efficiency of the steel plate, and thus improving work efficiency.

[0035] like Figure 2 , Figure 4 and Figure 6 As shown, a first spring telescopic rod 403 is elastically supported between the fixed bracket 401 and the movable plate 402, a second spring telescopic rod 404 is elastically supported between the top of the inner cavity of the fixed shell 1 and the movable plate 402, a connecting plate 506 is hingedly connected to the middle part of the fixed plate 6, a third spring telescopic rod 507 is elastically supported between the connecting plate 506 and the fixed plate 6, and a second rectangular rod 505 is movably connected to the bottom of the connecting plate 506.

[0036] The above scheme is adopted: through the design of the first spring telescopic rod 403 and the second spring telescopic rod 404, the first spring telescopic rod 403 is elastically supported between the fixed bracket 401 and the movable plate 402, so that when the movable rod 407 contacts the movable plate 402, the movable plate 402 moves, so that the first spring telescopic rod 403 limits the movable plate 402, so that the movable plate 402 is more stable when moving, and the second spring telescopic rod 404 is elastically supported between the top of the inner cavity of the fixed shell 1 and the movable plate 402, so that when the movable plate 402 drives the bellows 405 to contract or expand, the movable plate 402 is more stable when moving, thereby making the bellows 405 more stable, and then making the bellows 405 can better absorb dust and blow some smaller debris from the surface of the steel plate, so that the grinding effect is better. Through the cooperation of the connecting plate 506 and the third spring telescopic rod 507, the gear 502 rotates to drive the annular member 503 to move, and the annular member 503 drives the first rectangular rod 504 to move. The first rectangular rod 504 moves to resist the second rectangular rod 505, so that the first rectangular rod 504 and the second rectangular rod 505 are clamped, so that the second rectangular rod 505 drives the connecting plate 506 to flip downward. When the first rectangular rod 504 and the second rectangular rod 505 are unclamped, the third spring telescopic rod 507 drives the connecting plate 506 to reset, so that the debris can be better collected and processed.

[0037] like Figures 5 to 8 As shown, a slide groove is provided on one side of the fixed plate 6 close to the movable rod 407, and the inner wall of the slide groove is smooth, sliders are provided on both sides of the movable rod 407, and the fixed plate 6 is movably connected with the movable rod 407, the bottom of the movable plate 402 is an inclined surface, the top of the movable rod 407 is designed to be an inclined surface, and the connecting pipe 406 is abutted against the movable rod 407, the gear 502 is a half gear, the inner wall of the ring 503 is provided with teeth, and the gear 502 is meshed and connected with the ring 503.

[0038] The above scheme is adopted: through the cooperation between the fixed plate 6 and the movable rod 407, the design of the fixed plate 6 slide groove and the movable rod 407 slider, when the movable rod 407 moves in the fixed plate 6, the cooperation between the slide groove and the slider allows the movable rod 407 to limit the movable rod 407 when it moves, so that the movable rod 407 is more stable when it moves, and the inner wall of the slide groove is smooth, so that the movable rod 407 reduces the friction with the fixed plate 6 when it moves, thereby reducing the loss of the machine and thus increasing the service life of the machine. Through the design of the movable plate 402 and the movable rod 407, the movable plate 402 and the movable rod 407 are inclined. The surface design makes it more time-saving and labor-saving when the annular member 503 drives the movable rod 407 to resist the movable plate 402. Through the cooperation between the gear 502 and the annular member 503, the teeth on both sides of the gear 502 and the annular member 503 are meshed, so that the gear 502 drives the annular member 503 to reciprocate, and then the annular member 503 drives the movable rod 407 to move, so that the movable rod 407 resists the movable plate 402 at different heights, so that the bellows 405 contracts or expands, and then the bellows 405 absorbs and cleans the dust and some smaller debris generated by grinding.

[0039] like Figure 2 , Figure 4 and Figure 8 As shown, the third spring telescopic rod 507 is an arc-shaped spring telescopic rod, the lower end of the second rectangular rod 505 is provided with an inclined groove, the first rectangular rod 504 is abuttedly connected with the second rectangular rod 505, the lower end of the connecting pipe 406 is provided with a suction fan, and is fixedly installed on the fixed shell 1, and the side of the rectangular plate 9 close to the third spring telescopic rod 507 is an arc surface.

[0040] The above scheme is adopted: through the design of the third spring telescopic rod 507 and the second rectangular rod 505, the design of the third spring telescopic rod 507 is an arc spring telescopic rod, so that when the first rectangular rod 504 does not conflict with the second rectangular rod 505, the third spring telescopic rod 507 drives the connecting plate 506 and the second rectangular rod 505 to reset, so that the connecting plate 506 can cover the hole to prevent the dust from flying and falling on the surface of other components. If it is not cleaned in time, it will cause damage to the components. Through the cooperation of the connecting pipe 406 and the fixed shell 1, the connecting pipe A suction fan is designed at the lower end of 406, so that the suction fan can suck the dust and some lighter debris sucked by the bellows 405 into the connecting pipe 406, and finally drop them into the second storage tank 8. After a period of time, the cleaning personnel will remove the second storage tank 8 for regular cleaning, and fix it to the fixed shell 1 to fix the suction fan, thereby making the suction fan more stable when working. The curved surface design of the rectangular plate 9 allows the debris dropped by grinding to slide from the curved surface of the rectangular plate 9 to the surface of the third spring telescopic rod 507, thereby facilitating the cleaning of the debris generated by grinding.

[0041] like Figure 2 , Figure 6 As shown, one end of the movable rod 407 away from the movable plate 402 is fixedly connected to the annular member 503, a limiting groove is provided at the bottom of the connecting plate 506, a visual window is provided on the fixed shell 1, and a slot is provided on one side of the fixed shell 1 and is movably connected to the annular member 503.

[0042] The above scheme is adopted: through the cooperation of the movable rod 407 and the annular member 503, the movable rod 407 is fixedly connected with the annular member 503, so that the annular member 503 drives the movable rod 407 to move, and the movable rod 407 resists the movable plate 402, so that the movable plate 402 drives the bellows 405 to retract and expand, and the opening of the limiting groove at the bottom of the connecting plate 506 limits the second rectangular rod 505, so that the second rectangular rod 505 is more stable when moving, and through the design of the fixed shell 1 and the design of the visual window of the fixed shell 1, the operator can observe the grinding of the workpiece and its progress, and can also intuitively observe the dust and debris generated by the grinding of the CNC grinder, and the opening of the slot hole of the fixed shell 1 allows the annular member 503 to operate stably when moving, so that the annular member 503 can be moved better.

[0043] The working principle and use process of the present invention:

[0044] First, the steel plate to be ground is placed on the grinding unit 3, and the grinding force and distance memory of the grinding are adjusted by the control unit 2. After the adjustment is completed, the driving motor 501 is started, and the driving motor 501 drives the gear 502 to rotate, and the gear 502 drives the ring member 503 to rotate, and the rotation of the ring member 503 drives the movable rod 407 to move. When the movable rod 407 moves toward the rectangular plate 9 to resist the movable plate 402, the movable plate 402 moves upward, so that the first spring telescopic rod 403, the bellows 405 and the second spring telescopic rod 404 are contracted, so that the gas in the bellows 405 blows the debris on the surface of the steel plate, so that some easily falling debris falls from the surface of the steel plate, reducing the interference of the debris generated by the grinding, so that the effect of grinding the steel plate is better;

[0045] At the same time, the annular member 503 drives the first rectangular rod 504 to move to contact the second rectangular rod 505, so that the second rectangular rod 505 drives the connecting plate 506 to flip downward, so that the larger debris generated by the grinding unit 3 passes through the arc surface of the rectangular plate 9 and quickly falls into the first storage groove 7 at the bottom of the fixed plate 6, so that the debris generated by the grinding is quickly cleaned up. When the gear 502 is engaged with the teeth on the other side of the annular member 503, the movable rod 407 moves to the side away from the rectangular plate 9, and the second spring telescopic rod 404, the first spring telescopic rod 403 and the bellows 405 expand, so that the bellows 405 absorbs the dust and smaller debris generated by the grinding to the bellows In the pipe of tube 405, the suction fan at the lower end of connecting pipe 406 sucks the dust and smaller debris adsorbed by bellows 405 into the pipe of connecting pipe 406, thereby causing the dust and smaller debris in the pipe of connecting pipe 406 to fall into the second storage tank 8, and the second rectangular rod 505 and the first rectangular rod 504 are also no longer in conflict. At this time, the third spring telescopic rod 507 drives the connecting plate 506 to reset, thereby preventing the dust generated by the grinding unit 3 from flying through the holes in the fixed plate 6 to the surface of the bottom component, and failing to clean it in time, resulting in damage to the component, thereby avoiding consuming a lot of time on cleaning the debris, improving the grinding efficiency of the steel plate, and thus improving work efficiency.
