Detailed implementation manners
[0015] The technical solutions of the present application will be further described in detail below in conjunction with the specific implementation manners.
[0016] As Figure 1-7 shown, the present invention provides a technical solution: a high-precision cutting device for processing automotive parts, including a workbench 1, two fixed plates 2 are connected to the workbench 1, a support frame 3 is connected above the workbench 1, a plurality of support legs 4 are connected below the workbench 1, a baffle 5 is connected to the workbench 1, a blanking hopper 6 is connected to the workbench 1, a collection box 32 is slidably installed inside the workbench 1, a pull rod 33 is connected to the collection box 32, one inner wall of the collection box 32 is designed as an arc slope, and the collection box 32 is arranged below the blanking hopper 6 and the cutting groove 16. The arc slope on one side of the collection box 32 enables the debris to slide by itself, thus avoiding the concentrated accumulation of debris on one side of the collection box 32.

When the shielding cover 9 encloses the cutting area, the staff can observe the cutting situation through the observation window 30, and the handle 31 can facilitate the staff to push the shielding cover 9 to rotate.
[0018] An electric push rod 10 is fixedly installed inside the workbench 1. The movable end of the electric push rod 10 is connected to a fixed frame 11. A movable rod 12 is connected to the fixed frame 11. A connecting sleeve 13 is rotatably connected to the fixed rod 7. Both ends of the connecting sleeve 13 are connected to a connecting plate 14. An inclined table 15 is connected to the connecting sleeve 13. The connecting plate 14 and the inclined table 15 are perpendicular to each other. A guiding groove 35 is formed in the connecting plate 14. The movable rod 12 slides in the guiding groove 35. When the electric push rod 10 pulls the fixed frame 11 to move the movable rod 12, both ends of the movable rod 12 will slide in the guiding groove 35 and push the connecting plate 14 to make the connecting sleeve 13 rotate on the fixed rod 7, prompting the inclined table 15 to rotate and tilt, so that the scattered debris slides into the blanking hopper 6 and falls from the blanking hopper 6 into the collection box 32 for collection.
[0019] Cutting grooves 16 are formed in both the inclined table 15 and the workbench 1. Two fixed plates 2 on the workbench 1 are connected to a first grooved plate 17 through a rectangular frame. A first motor 18 is fixedly installed on the first grooved plate 17. The output shaft of the first motor 18 is connected to a threaded rod 19. A movable strip 20 is threadedly fitted on the threaded rod 19. The threaded rod 19 is rotatably connected inside the first grooved plate 17. A guiding rod 37 is connected inside the first grooved plate 17. The movable strip 20 is slidably connected to the guiding rod 37 and is slidably arranged inside the first grooved plate 17. Two ends of the lower part of the movable strip 20 are connected to supporting wheels 38. The movement of the movable strip 20 is guided by the guiding rod 37 to prevent the movable strip 20 from rotating and skewing during movement, so that the pressing plate 22 moves smoothly to press the plate.
[0020] Connecting strips 21 are connected to both sides of the movable strip 20. A pressing plate 22 is connected to the connecting strips 21. The pressing plate 22 slides on the fixed plate 2. A rubber pad 36 is connected to one side of the pressing plate 22. There are four supporting legs 4 arranged in a rectangular array, and an anti-slip rubber layer is provided below the supporting legs 4. During the contact between the pressing plate 22 and the plate, the rubber pad 36 will be squeezed, so as to be in close contact with the plate, increasing friction and thus improving the stability of clamping.
[0021] Two hydraulic push rods 23 are fixedly installed on the support frame 3. The movable end of the hydraulic push rod 23 is connected to a second slotted plate 24. A second motor 25 is fixedly installed on one side of the second slotted plate 24. The output shaft of the second motor 25 is connected to a threaded lead screw 26. An installation table 27 is installed on the threaded lead screw 26 in a threaded fit manner. A cutting wheel 28 is rotatably installed on the installation table 27. A working motor 29 is fixedly installed on one side of the installation table 27. The threaded lead screw 26 is rotatably connected inside the second slotted plate 24. The upper half of the installation table 27 slides inside the second slotted plate 24 and is in close contact with the groove wall. The output shaft of the working motor 29 is connected to the cutting wheel 28. The position of the cutting wheel 28 corresponds to the cutting groove 16. A plurality of sliding plates 34 are connected above the second slotted plate 24. The sliding plates 34 are slidably connected to the support frame 3. When the hydraulic push rod 23 pushes the second slotted plate 24 downward, the sliding plates 34 will slide on the support frame 3, thereby shielding the area on one side of the support frame 3 and reducing the flying debris everywhere.
[0022] A usage method of a high-precision cutting device for processing automotive parts, the usage method includes the following steps: The staff places the parts preparation plate on the workbench 1 from one side of the workbench 1 and makes one side of the plate contact the baffle 5. Then, the staff starts the first motor 18, so that the first motor 18 drives the threaded rod 19 to rotate in the first slotted plate 17, prompting the movable strip 20 in threaded fit with the threaded rod 19 to move along the threaded rod 19. At this time, the support wheel 38 can roll on the workbench 1, so that the movable strip 20 drives the pressing plate 22 through the connecting strip 21, prompting the pressing plate 22 to slide on the fixing plate 2; Furthermore, the pressing plate 22 contacts the plate, and the pressing plate 22 cooperates with the baffle 5 to clamp and fix the plate, preventing the plate from sliding and shifting during cutting, thereby improving the cutting accuracy. When the pressing plate 22 contacts the baffle 5, the rubber pad 36 will be squeezed, so as to be in close contact with the plate and improve the clamping stability. Then, the working motor 29 is started to drive the cutting wheel 28 to rotate, and the staff can push the second slotted plate 24 downward by starting the hydraulic push rod 23, prompting the cutting wheel 28 to approach the cutting groove 16 and contact the plate; Then, the second motor 25 is started to rotate the threaded lead screw 26, prompting the installation table 27 in threaded fit with the threaded lead screw 26 to slide along the threaded lead screw 26 inside the second slotted plate 24, thereby driving the cutting wheel 28 to move to complete the cutting. During cutting, the staff can push the shielding cover 9 to rotate through the grip 31, so that the shielding cover 9 encloses the cutting area, thereby avoiding the flying of cutting debris everywhere and preventing the surrounding staff from being injured. After cutting is completed, the hydraulic push rod 23 is controlled to pull the second slotted plate 24 upward and rotate the shielding cover 9; After that, start the electric push rod 10 to pull the fixed frame 11 to move. At this time, the movable rod 12 will be driven by the fixed frame 11, so that both ends of the movable rod 12 can slide in the guide groove 35, and at the same time, push the connecting plate 14 to cause the connecting sleeve 13 to rotate on the fixed rod 7. Furthermore, the connecting sleeve 13 drives the inclined table 15 to rotate, making the inclined table 15 tilt upward, so that the debris falling on the inclined table 15 slides into the blanking hopper 6, and then centrally falls into the collection box 32 for collection. The operation is simple, reducing the labor intensity of manual cleaning.
