[0009] Preferably, a side plate is fixedly connected to the top side of the fixed frame, a support column is installed on the top side of the fixed frame, a stepper motor is installed at the top of the support column, a gear is installed at the output end of the stepper motor, two slide rails are symmetrically arranged around the central axis inside the side plate, a slider is slidably installed inside the slide rail, a rack is fixedly connected to one side of each slider, the rack meshes with the top and bottom sides of the gear respectively, a protective door is fixedly connected to the other side of each slider, two slide tracks are opened on the top side of the worktable, a movable block is fixedly connected to the bottom side of the protective door, the movable block is slidably installed inside the slide track, and the protective door is driven to open and close by a gear and rack mechanism, effectively preventing the splashing of waste chips during processing.

[0010] Preferably, a water collection cavity is provided inside the workbench below the fixed frame, and several through holes are provided at equal intervals inside the fixed frame.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figure 1 , 2 As shown in Figures 3 and 5, a dust suppression device for workpiece processing includes a workbench 1. A fixed frame 2 is installed at one end of the top side of the workbench 1. A conveying pipe 3 is assembled on the top side of the fixed frame 2. Five spray nozzles 4 are equidistantly installed on the bottom side of the conveying pipe 3. A connecting pipe 5 is installed on the top side of the end of the conveying pipe 3. A water filling cylinder 6 is connected to the top of the connecting pipe 5. A water inlet pipe 7 is connected to one side of the bottom end of the water filling cylinder 6. Valves 8 are installed inside both the water inlet pipe 7 and the connecting pipe 5. A piston plate 9 is slidably installed inside the water filling cylinder 6 above the water inlet pipe 7. A connecting rod 10 is installed on the top side of the piston plate 9. A connecting plate 11 is installed on the top of the connecting rod 10. A cylinder 12 is installed on the top side of the fixed frame 2. An actuating rod 13 is installed on the working end of the cylinder 12. One end of the connecting plate 11 is installed on the top side of the actuating rod 13.

[0024] A side plate 26 is fixedly connected to the top side of the fixed frame 2. A support column 27 is installed on the top side of the fixed frame 2. A stepper motor 28 is installed at the top of the support column 27. A gear 29 is installed at the output end of the stepper motor 28. Two slide rails 30 are symmetrically arranged inside the side plate 26 along the central axis. A slider 31 is slidably installed inside the slide rail 30. A rack 32 is fixedly connected to one side of each slider 31. The rack 32 meshes with the top and bottom sides of the gear 29, respectively. A protective door 33 is fixedly connected to the other side of each slider 31. Two slide tracks 34 are opened on the top side of the workbench 1. A movable block 35 is fixedly connected to the bottom side of the protective door 33. The movable block 35 is slidably installed inside the slide track 34.

[0025] The workbench 1 has a water collection cavity 36 located below the fixed frame 2. The fixed frame 2 has several through holes 37 equidistantly arranged inside, and the through holes 37 are connected to the water collection cavity 36. During operation, in practical applications, the drill bit 42 will splash in all directions under high-speed rotation. If there is no water spray to suppress dust, the dust will spread with the air flow in the workshop, polluting a wider working environment. After the milling cutter is fixed, the stepper motor 28 starts, and its output end drives the gear 29 to rotate. Since the rack 32 meshes with the top and bottom sides of the gear 29 respectively, the rotation of the gear 29 will cause the two racks 32 to make linear movements in opposite or opposite directions, thereby driving the protective door 33 to slide in the slide rail 34 through the movable block 35, realizing the opening and closing action of the protective door 33. When the protective door 33 is closed, a rectangular hole is reserved between the two, which facilitates the installation frame 40 to enter the interior of the fixed frame 2, effectively preventing the splashing of waste chips during processing.

[0026] During drilling, cylinder 12 is activated, and its working end drives connecting plate 11 to move up and down via actuating rod 13. This causes connecting rod 10 to drive piston plate 9 to slide up and down inside water filling cylinder 6. When piston plate 9 moves upward, the lower space inside water filling cylinder 6 increases. At this time, valve 8 in water inlet pipe 7 opens, and valve 8 in connecting pipe 5 closes, allowing water to be drawn into water filling cylinder 6. When piston plate 9 moves downward, the lower space inside water filling cylinder 6 decreases. Valve 8 in water inlet pipe 7 closes, and valve 8 in connecting pipe 5 opens, allowing water to be forced into connecting pipe 5 and into conveying pipe 3. Finally, water is sprayed out from five spray nozzles 4, achieving intermittent water supply to conveying pipe 3 and spray nozzles. The sprayed water comes into contact with dust generated during processing, causing the dust to settle. The sprayed water flows into water collection chamber 36 through through hole 37, ensuring that the water flowing out during processing can be collected and treated in a centralized manner, avoiding environmental pollution.

[0027] Please see Figure 1 , 2As shown in Figures 4 and 5, a servo motor 14 is installed on the top side of the fixed frame 2, a threaded rod 15 is installed on the output end of the servo motor 14, a sliding groove 16 is opened on the inner side of the fixed frame 2, a sliding block 17 is slidably installed inside the sliding groove 16, a screw hole is opened inside the sliding block 17, and one end of the threaded rod 15 passes through the screw hole and is rotatably installed inside the bottom side of the fixed frame 2.

[0028] A mounting cavity 18 is installed on one side of the sliding block 17. A drive motor 19 is installed on the inner wall of the mounting cavity 18. A turntable 20 is installed on the working end of the drive motor 19. Two arc-shaped grooves 21 are equally spaced inside the turntable 20. A slide rod 22 is slidably installed inside each arc-shaped groove 21. A moving block 23 is fixedly connected to one end of each slide rod 22. Two rectangular grooves 24 are equally spaced inside one side of the mounting cavity 18. The moving block 23 is slidably installed inside the rectangular grooves 24. A fixing clamp 25 is fixedly connected to one side of each moving block 23.

[0029] A support plate 38 is installed at the other end of the top side of the workbench 1. A hydraulic cylinder 39 is installed on one side of the support plate 38. A mounting frame 40 is installed at the working end of the hydraulic cylinder 39. A drilling motor 41 is installed inside the mounting frame 40. A drill bit 42 is installed at the output end of the drilling motor 41. During operation, in order to stably complete the drilling operation of the milling cutter, the milling cutter is first placed between the fixed clamping plates 25. The drive motor 19 is started, which drives the turntable 20 to rotate. When the turntable 20 rotates, the slide rod 22 pushes the moving block 23 to move closer or further away from each other, thereby driving the fixed clamping plate 25 to clamp or release the milling cutter to adapt to milling cutters of different sizes and ensure its stability during the processing. Then, the servo motor 14 is started, and its output end drives the threaded rod 15 to rotate, which causes the sliding block 17 to move up and down along the slide groove 16, thereby realizing the precise adjustment of the vertical position of the milling cutter, so that the position where the milling cutter needs to be drilled is on the same horizontal line as the drill bit 42, to meet different processing requirements.

[0030] Finally, the hydraulic cylinder 39 operates, and its working end pushes the mounting frame 40 to move, so that the drilling motor 41 and the drill bit 42 at its output end in the mounting frame 40 reach the appropriate processing position. The drilling motor 41 starts and drives the drill bit 42 to rotate, performing precise drilling operations on the workpiece.

[0031] Working principle: First, the milling cutter is placed between the fixed clamping plates 25. The drive motor 19 is started, which drives the turntable 20 to rotate. When the turntable 20 rotates, the slide bar 22 pushes the moving block 23 to move closer or further away from each other, thereby driving the fixed clamping plate 25 to clamp or release the milling cutter to accommodate milling cutters of different sizes and ensure their stability during processing. Then, the servo motor 14 is started, and its output end drives the threaded rod 15 to rotate, which causes the sliding block 17 to move up and down along the slide groove 16, thereby realizing the precise adjustment of the vertical position of the milling cutter, so that the position where the milling cutter needs to drill is on the same horizontal line as the drill bit 42, to meet different processing requirements.

[0032] After the milling cutter is fixed, the stepper motor 28 starts, and its output drives the gear 29 to rotate. Since the rack 32 meshes with the top and bottom sides of the gear 29 respectively, the rotation of the gear 29 will cause the two racks 32 to make linear motion in opposite or opposite directions, thereby driving the protective door 33 to slide in the slide rail 34 through the movable block 35, realizing the opening and closing action of the protective door 33. When the protective door 33 is closed, a rectangular hole is reserved between the two, which makes it easy for the mounting frame 40 to enter the interior of the fixed frame 2, effectively preventing the splashing of waste chips during the processing.

[0033] When drilling is performed, cylinder 12 is activated, and its working end drives connecting plate 11 to move up and down through rod 13. This causes connecting rod 10 to drive piston plate 9 to slide up and down inside water cylinder 6. When piston plate 9 moves upward, the lower space inside water cylinder 6 increases. At this time, valve 8 in water inlet pipe 7 opens and valve 8 in connecting pipe 5 closes, and water is drawn into water cylinder 6. When piston plate 9 moves downward, the lower space inside water cylinder 6 decreases. Valve 8 in water inlet pipe 7 closes and valve 8 in connecting pipe 5 opens, and water is forced into connecting pipe 5 and into delivery pipe 3. Finally, water is sprayed out from five spray nozzles 4, achieving intermittent water supply to delivery pipe 3 and spray nozzles. The sprayed water comes into contact with dust generated during processing, causing the dust to settle. The sprayed water flows into water collection chamber 36 through through hole 37, ensuring that the water flowing out during processing can be collected and treated in a centralized manner to avoid environmental pollution.

[0034] Finally, the hydraulic cylinder 39 operates, and its working end pushes the mounting frame 40 to move, so that the drilling motor 41 and the drill bit 42 at its output end in the mounting frame 40 reach the appropriate processing position. The drilling motor 41 starts and drives the drill bit 42 to rotate, performing precise drilling operations on the workpiece.
