[0001] This utility model relates to the field of machining, specifically a protective device for milling machine machining. Background Technology
[0002] During milling, the cutting tool rotates at high speed while the workpiece moves slowly in a straight line (feed motion). The main safety hazards caused by this motion are the high-speed rotating milling cutter and the chips generated during milling. To prevent accidents such as the cutting tool getting caught between the operator's hand or clothing and the workpiece, sudden tool breakage, or the workpiece flying out during operation, it is necessary to install appropriate protective devices on the milling machine.
[0003] Milling machine safety devices are crucial for ensuring the safety of milling machine operators. Selecting appropriate safety devices, following installation and maintenance procedures, and adhering to safe operating procedures are essential for preventing accidents during milling operations.
[0004] Existing milling machines typically fix the workpiece directly on the worktable for processing, which generates a large amount of debris during the process. During use and observation, it was found that these debris are carried by the rotating cutter head and splashed in all directions, which causes pollution around the worktable and affects subsequent processing.
[0005] Therefore, a milling machine protection device is proposed to address the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a milling machine machining protection device includes an operating table 1; a linear motor 11 is fixedly connected to the operating table 1; a fixed platform 12 is slidably connected to the linear motor 11; a support column 13 is fixedly connected to the operating table 1; a connecting column 14 is fixedly connected to the end of the support column 13; a hydraulic cylinder 15 is fixedly connected to the connecting column 14; a motor 16 is fixedly connected to the output end of the hydraulic cylinder 15; a rotating shaft 17 is fixedly connected to the output end of the motor 16; a cutting head 18 is fixedly connected to the end of the rotating shaft 17; a first connecting plate 19 is fixedly connected to the motor 16; the first connecting plate 19 and the rotating shaft 17 are through-connected and rotatably connected; a plurality of connecting components 110 are fixedly connected to the first connecting plate 19; a second connecting plate 111 is fixedly connected to the other end of the connecting component 110; a through hole 112 is opened on the second connecting plate 111; the through hole 112 and the cutting head 18 are correspondingly arranged; a splash guard is fixedly connected between the first connecting plate 19 and the second connecting plate 111. The anti-splash cloth 113; the rotating shaft 17 is located inside the anti-splash cloth 113. When the workpiece needs to be processed, the workpiece is placed on the fixed table 12 for fixation. Then, the linear motor 11 is turned on to transport the workpiece to the designated position. When the workpiece reaches the designated position, the motor 16 is turned on. When the motor 16 is turned on, it drives the rotating shaft 17 fixed to the output end of the motor 16 to rotate. When the rotating shaft 17 rotates, it drives the cutter head 18 fixed to the end of the rotating shaft 17 to rotate. The rotating cutter head 18 processes the workpiece. The position of the cutter head 18 can be adjusted by adjusting the length of the hydraulic cylinder 15 so as to process the workpiece to different depths. When the cutter head 18 rotates to process the workpiece, it will generate debris. The debris will splash around the cutter head 18. When the debris moves to a certain position, the anti-splash cloth 113 blocks the splashed debris. By fixing the anti-splash cloth 113 between the first connecting plate 19 and the second connecting plate 111, the debris splashed during the workpiece processing can be blocked, reducing the situation of debris splashing during use.
[0026] like Figure 2As shown, the connecting assembly 110 includes a telescopic rod 2; the telescopic rod 2 and the first connecting plate 19 are fixedly connected; the other end of the telescopic rod 2 is fixedly connected to the connecting assembly 110; a spring 21 is fixedly connected to the first connecting plate 19; the other end of the spring 21 is fixedly connected to the connecting assembly 110; the telescopic rod 2 is located inside the spring 21. When the hydraulic cylinder 15 moves, it drives the motor 16 to move towards the fixed platform 12. When the motor 16 moves, it drives the second connecting plate 111 to move. When the second connecting plate 111 moves to a designated position, it contacts the workpiece surface. At this time, the telescopic rod 2 and the spring 21 are compressed. When the telescopic rod 2 and the spring 21 are compressed to a certain position... When the cutting head 18 contacts the workpiece surface to process the workpiece, after the cutting head 18 completes the processing, it moves towards the connecting column 14. At this time, under the action of the spring 21, the second connecting plate 111 moves towards the fixed platform 12. When the second connecting plate 111 moves to the designated position, the anti-splash cloth 113 is stretched to cover the cutting head 18. A telescopic rod 2 is fixed between the first connecting plate 19 and the second connecting plate 111, and a spring 21 is fixed outside the telescopic rod 2. When the spring 21 extends, it covers the cutting head 18, which allows the anti-splash cloth 113 to be in an extended state after use, reducing the situation where the debris attached to the cutting head 18 is thrown out in all directions.
[0027] like Figure 3 As shown, a pair of connecting strips 3 are fixedly connected to the rotating shaft 17; multiple first bristles 31 are fixedly connected to the connecting strips 3. When the rotating shaft 17 rotates, it drives the cutter head 18 to rotate and process the workpiece. When the cutter head 18 processes the workpiece, the debris generated will adhere to the anti-splash cloth 113. When the rotating shaft 17 rotates, it drives the connecting strips 3 to rotate. When the connecting strips 3 rotate, they drive the first bristles 31 to rotate. When the first bristles 31 rotate, they contact the surface of the anti-splash cloth 113 and clean the surface of the anti-splash cloth 113. By fixing multiple connecting strips 3 to the connecting strips 3, the surface of the anti-splash cloth 113 is cleaned when the first bristles 31 contact the anti-splash cloth 113, reducing the accumulation of debris and impurities on the surface of the anti-splash cloth 113.
[0028] like Figure 4 As shown, multiple elastic ropes 4 are fixedly connected to the telescopic rod 2; the other end of the elastic rope 4 is fixedly connected to the splash-proof cloth 113. During use, when the splash-proof cloth 113 moves towards the cutter head 18, the elastic rope 4 stretches the splash-proof cloth 113. By fixing multiple elastic ropes 4 to the telescopic rod 2, the elastic rope 4 can stretch the splash-proof cloth 113 during use, keeping the splash-proof cloth 113 in an extended state and reducing the possibility of the splash-proof cloth 113 moving towards the cutter head 18.
[0029] like Figure 5As shown, multiple buffer blocks 5 are fixedly attached to the second connecting plate 111. The buffer blocks 5 are made of flexible material. When the second connecting plate 111 moves to a designated position, the buffer blocks 5 contact the workpiece surface. When the buffer blocks 5 contact the workpiece surface, they press the workpiece. By fixing multiple buffer blocks 5 to the second connecting plate 111, the workpiece can be pressed during the processing, reducing the shaking of the second connecting plate 111 during the processing. At the same time, it can reduce the situation where the second connecting plate 111 directly contacts the workpiece surface, causing scratches on the workpiece.
[0030] like Figure 5 As shown, a plurality of second brush bristles 6 are fixedly attached to the through hole 112. The second brush bristles 6 are arranged in an array. When the cutter head 18 completes the processing of the workpiece, the second connecting plate 111 moves away from the motor 16 under the action of the spring force of the spring 21. At this time, the cutter head 18 and the second brush bristles 6 come into contact. When the cutter head 18 and the second brush bristles 6 come into contact, the impurities and debris attached to the cutter head 18 are cleaned. By fixing a plurality of second brush bristles 6 to the through hole 112, the debris and impurities attached to the cutter head 18 can be cleaned, reducing the situation where debris and impurities adhere to the cutter head 18 and affect the subsequent processing of the workpiece by the cutter head 18.
[0031] Working principle: When a workpiece needs to be processed, it is placed on the fixed table 12 and fixed. Then, the linear motor 11 is turned on to transport the workpiece to the designated position. When the workpiece reaches the designated position, the motor 16 is turned on. When the motor 16 is turned on, it drives the rotating shaft 17 fixed to the output end of the motor 16 to rotate. When the rotating shaft 17 rotates, it drives the cutter head 18 fixed to the end of the rotating shaft 17 to rotate. The rotating cutter head 18 processes the workpiece. Adjusting the length of the hydraulic cylinder 15 can adjust the position of the cutter head 18 to perform different depths of processing on the workpiece. When the cutter head 18 rotates and processes the workpiece, it will generate chips. Debris splashes around the cutter head 18. When the debris reaches a certain position, the anti-splash cloth 113 blocks the splashing debris. When the hydraulic cylinder 15 moves, it drives the motor 16 to move towards the fixed platform 12. When the motor 16 moves, it drives the second connecting plate 111 to move. When the second connecting plate 111 moves to the designated position, it contacts the workpiece surface. At this time, the telescopic rod 2 and the spring 21 are compressed. When the telescopic rod 2 and the spring 21 are compressed to a certain extent, the cutter head 18 contacts the workpiece surface to process the workpiece. After the cutter head 18 completes the processing of the workpiece, it moves towards... When the connecting column 14 moves, the second connecting plate 111 moves towards the fixed platform 12 under the action of the spring 21. When the second connecting plate 111 moves to the designated position, the splash-proof cloth 113 is stretched to cover the cutter head 18. When the rotating shaft 17 rotates, it drives the cutter head 18 to rotate and perform machining on the workpiece. When the cutter head 18 performs machining on the workpiece, the debris generated will adhere to the splash-proof cloth 113. When the rotating shaft 17 rotates, it drives the connecting strip 3 to rotate. When the connecting strip 3 rotates, it drives the first brush bristles 31 to rotate. When the first brush bristles 31 rotate, they contact the surface of the splash-proof cloth 113. The surface of the splash-proof cloth 113 is cleaned. During use, when the splash-proof cloth 113 moves towards the cutter head 18, the elastic rope 4 stretches the splash-proof cloth 113. When the second connecting plate 111 moves to the designated position, the buffer block 5 contacts the workpiece surface. When the buffer block 5 contacts the workpiece surface, it presses the workpiece. When the cutter head 18 completes the processing of the workpiece, the second connecting plate 111 moves away from the motor 16 under the action of the spring 21. At this time, the cutter head 18 and the second brush bristles 6 come into contact. When the cutter head 18 and the second brush bristles 6 come into contact, the impurities and debris attached to the cutter head 18 are cleaned.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
