Description

Technical Field

[0001] This invention relates to the field of automotive parts processing, and in particular to an integrated grinding device for automotive sheet metal parts. Background Technology

[0002] Sheet metal processing is a comprehensive cold working process for thin metal sheets (usually less than 6mm thick), including shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming (such as car bodies). Products processed by the sheet metal industry are called sheet metal parts. Sheet metal parts are characterized by their light weight, high strength, electrical conductivity (which can be used for electromagnetic shielding), low cost, and good performance for large-scale mass production. They are widely used in electronics, communications, automotive, and medical device industries.

[0003] In existing technologies, grinding sheet metal parts generates a significant amount of metal dust. This dust greatly degrades the working environment of the grinding workshop, harming the health of workers and potentially leading to employee turnover. While dust-removing grinding equipment has been designed, most existing systems rely on exhaust fans located at the bottom or rear of the grinding table. Since these fans are only positioned in one area, effectively removing the dust requires high-powered fans or vortex fans to remove dust even from areas far from the exhaust fan. This significantly increases energy consumption and generates considerable noise. Furthermore, the exhaust fans inevitably have vents. The mixture of dust and air passes through a filter and is discharged through the vent. However, due to the limitations of the filters, not all dust is collected inside the exhaust fan, and smaller particles continue to escape. Long-term inhalation of these small particles can damage the lungs and respiratory tract of workers.

[0004] Therefore, it is necessary to invent an integrated grinding device for automotive sheet metal parts to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated grinding device for automotive sheet metal parts, so as to solve the problems mentioned in the background art.

[0007] The water injection assembly includes water-filling pipes arranged in an equidistant ring around the outer periphery of the plug sleeve. The end of the water-filling pipe away from the plug sleeve extends into the interior of the hollow cylinder and is fixedly connected to the piston plate. The end of the piston plate away from the water-filling pipe is fixedly connected to the end of the hollow cylinder away from the water-filling pipe via a compression spring. The end of the hollow cylinder away from the water-filling pipe has a water-intake hole. The piston plate has a water-outtake hole that communicates with the interior of the water-filling pipe. Both the water-intake hole and the water-outtake hole are equipped with a one-way valve. The side of the water-filling pipe facing the wetted sponge disc has a water-spraying hole. The hollow cylinder can move back and forth along its axis. A first water tank is located below the wetted sponge disc. When the hollow cylinder rotates, it passes through the interior of the first water tank.

[0008] Preferably, the side of the water filling pipe facing the wetted sponge disc is fixedly provided with a water injection pipe that communicates with the water spray hole. The water injection pipe is inserted into the interior of the wetted sponge disc, and the surface of the water injection pipe is provided with a water injection hole that communicates with the interior. The end of the water injection pipe away from the water filling pipe is a pointed cone shape.

[0009] Preferably, the inner wall of the first water tank is fixedly provided with an extrusion plate, and when the hollow column passes over the surface of the extrusion plate, the compression spring inside the hollow column is in a compressed state.

[0010] Preferably, a hollow ring is provided around the first drive motor to cover it, and an annular cavity is provided inside the hollow ring. A water supply pipe is provided at the bottom of the hollow ring. A water filling component is provided inside the first water tank to fill the water supply pipe with water. A downwardly inclined drain pipe is provided on the water supply pipe near the dust collection box. A one-way valve is provided inside the drain pipe and on the water supply pipe. The one-way valve on the water supply pipe is located below the inner port of the drain pipe.

[0011] Preferably, the water filling component includes an air bladder, which is fixedly connected to the inner wall of the first water tank. The air bladder is in communication with the interior of the water supply pipe. The air bladder has a water inlet, and a one-way valve is provided inside the water inlet. When the hollow column passes through the air bladder, the air bladder is in a compressed state.

[0012] Preferably, the hollow column is rotatably connected to a sleeve, which passes over the surface of the airbag component as the hollow column moves.

[0013] Preferably, the hollow column is located at the periphery of the wetted sponge disc, and when the hollow column moves toward the insertion sleeve, it squeezes the outer periphery of the wetted sponge disc.

[0014] Preferably, the top of the hollow ring is fixedly connected to one end of the buffer tube, and the other end of the buffer tube extends out of the dust collection box.

[0015] Preferably, the top of the dust collection box is provided with a second water tank, and the bottom of the second water tank is provided with a recess for accommodating the second drive motor. The top end of the buffer tube extends into the interior of the second water tank and is inclined toward the second drive motor. A reflux hole is provided on the buffer tube near the bottom of the second water tank, and a one-way valve is provided inside the reflux hole.

[0016] Preferably, the shaft of the second drive motor is provided with a limiting protrusion, and the inner wall of the plug sleeve is provided with a limiting groove that matches the limiting protrusion.

[0017] The technical effects and advantages of this invention are as follows:

[0018] 1. The wetted sponge disc in this invention can adsorb these small particles, thereby making the air discharged from the wetted sponge disc cleaner and less polluting to the environment. At the same time, the water injection component can fill the interior of the wetted sponge disc with water and keep it in a moist state. In addition, the wetted sponge disc in this invention can be disassembled from the outside of the plug sleeve, making it easy to replace the wetted sponge disc with dust to ensure the adsorption effect of the wetted sponge disc on dust.

[0019] 2. The dust suction head of the present invention is located at the free end of the mechanical cantilever near the grinding head, so that the dust suction head can move with the grinding head to achieve more precise dust suction. Compared with traditional large-area air extraction and dust removal, the present invention only removes dust from the area where dust is being generated during grinding, thus eliminating the need for energy-consuming components such as high-power air pumps or motors, and eliminating the need for air extraction in areas where dust removal is not required, thereby reducing energy consumption and production costs.

[0020] 3. The water injection pipe is inserted into the interior of the wet sponge tray to fix and limit the position of the wet sponge tray, so that the wet sponge tray can rotate stably in the vertical plane with the water injection pipe. This allows different parts of the wet sponge tray to contact the opening of the dust collection box, preventing a certain part of the wet sponge tray from always being in the position corresponding to the opening of the dust collection box and becoming saturated with adsorption, thus avoiding a reduction in the dust removal effect of the wet sponge tray.

[0021] 4. Each time the water filling component fills the hollow ring with water, it can cool down the first drive motor. The water that has entered the hollow ring and has slightly increased in temperature will be discharged back into the first water tank through the drain pipe, realizing the effect of "circulating water cooling", thus making the cooling effect on the first drive motor better.

[0022] 5. Because the extrusion plate is located near the bottom of the wet sponge tray, the hollow column will squeeze the outer periphery of the wet sponge tray near the bottom edge. As the water absorbed by the wet sponge tray will sink to the bottom of the wet sponge tray under gravity, the extrusion of the hollow column on the side of the wet sponge tray near the bottom can squeeze out the supersaturated water absorbed by the bottom of the wet sponge tray and let it fall into the first water tank for recycling. This also prevents the saturated parts of the wet sponge tray from affecting the air exhaust inside the dust collection box. At the same time, it prevents the bottom of the wet sponge tray from becoming too heavy due to water settling, thus preventing the wet sponge tray from being pulled downward and deformed. It also prevents the adsorption holes on the wet sponge tray from becoming blocked or enlarged after deformation, which would affect the dust adsorption effect.

[0023] 6. When the water sprayed from the buffer pipe falls to the bottom of the second water tank at the position corresponding to the second drive motor, the temperature of the cold water will be transferred to the second drive motor through the second water tank, which will cool the second drive motor. The water that falls to the bottom of the second water tank will enter the water supply pipe again through the return hole and then enter the first water tank through the drain pipe, completing a cycle.

[0034] This invention provides, for example Figures 1-7 The illustrated integrated grinding device for automotive sheet metal parts includes a grinding box 1. A rotating grinding head 3 is located inside the grinding box 1. The grinding head 3 is connected to the free end of a mechanical cantilever 2. A suction head 4 is located near the grinding head 3 at the free end of the mechanical cantilever 2. The suction head 4 is fixedly connected to one end of a suction pipe 5, and the other end of the suction pipe 5 is connected to one end of a suction box 6. The suction box 6 is a horizontally placed cylindrical structure with one open end, and the opening of the suction box 6 is located at the end away from the suction pipe 5. The interior of the suction box 6... The dust collection box 6 is equipped with a filter screen 14. Inside the dust collection box 6, between the filter screen 14 and the opening, there is a rotating turbine 15. The turbine 15 is driven by a first drive motor 19. A second drive motor 21 is horizontally placed at the top of the dust collection box 6 near the opening. A plug-in sleeve 22 is fitted on the shaft of the second drive motor 21. A wetted sponge tray 7 is coaxial with the plug-in sleeve 22. The wetted sponge tray 7 covers the opening of the dust collection box 6. A water injection component for injecting water into the wetted sponge tray 7 is also provided outside the plug-in sleeve 22.

[0035] The water injection assembly includes water-filling pipes 8 arranged in an equidistant ring around the outer periphery of the plug sleeve 22. The end of the water-filling pipe 8 away from the plug sleeve 22 extends into the interior of the hollow column 9 and is fixedly connected to the piston plate 26. The end of the piston plate 26 away from the water-filling pipe 8 is fixedly connected to the end of the hollow column 9 away from the water-filling pipe 8 by a compression spring. The end of the hollow column 9 away from the water-filling pipe 8 is provided with a water-absorbing hole 30. The piston plate 26 is provided with a water-discharging hole 31 that communicates with the interior of the water-filling pipe 8. Both the water-absorbing hole 30 and the water-discharging hole 31 are provided with a one-way valve. The side of the water-filling pipe 8 facing the wetted sponge plate 7 is provided with a water-spraying hole 32. The hollow column 9 can move back and forth along its axis. A first water tank 12 is provided below the wetted sponge plate 7. When the hollow column 9 rotates, it passes through the interior of the first water tank 12.

[0036] In actual operation, the workpiece to be processed can be placed inside the grinding box 1. The mechanical cantilever 2 can drive the grinding head 3 to move in various directions inside the grinding box 1, thereby achieving all-round grinding of the workpiece surface and edges. During the grinding process, the turbine 15 rotates under the drive of the first drive motor 19 and generates negative pressure, so that the dust generated by grinding inside the grinding box 1 will enter the suction pipe 5 through the suction head 4 and then enter the inside of the suction box 6 for collection. The extracted air will pass through the filter screen 14 inside the suction box 6 and be discharged from the opening of the suction box 6. Since the filter screen 14 can only filter particles of a certain size, in actual application, some small particles smaller than the pore size of the filter screen 14 will also be discharged from the opening of the suction box 6. The wetted sponge plate 7 can adsorb these small particles, thereby making the air discharged from the wetted sponge plate 7 cleaner and less polluting to the environment.

[0037] Meanwhile, to ensure the soaked sponge disc 7 remains moist, the present invention includes a water-filling pipe 8 and a hollow column 9. When the hollow column 9 passes through the first water tank 12, it moves back and forth within the tank. When the hollow column 9 first moves towards the insertion sleeve 22, air inside it enters the water-filling pipe 8 through the water outlet 31 and exits through the spray nozzle 32. Conversely, when the hollow column 9 moves away from the insertion sleeve 22... When the device moves, the water inside the first water tank 12 will enter the hollow column 9 through the water suction hole 30 for storage. When the hollow column 9 moves closer to the plug sleeve 22, the water inside the hollow column 9 will enter the water filling pipe 8 through the water outlet 31 and be sprayed from the water spray hole 32 on the water filling pipe 8 onto the surface of the wet sponge plate 7 and absorbed by the wet sponge plate 7, thereby keeping the wet sponge plate 7 moist, which facilitates further purification of the air sprayed from the opening of the dust collection box 6.

[0038] The dust suction head 4 of the present invention is located at the free end of the mechanical cantilever 2 near the grinding head 3. Thus, the dust suction head 4 can move with the grinding head 3 to achieve more precise dust suction. Compared with traditional large-area air extraction and dust removal, the present invention only removes dust from the part that is being ground and generates dust. Therefore, it does not need to use energy-consuming components such as high-power air pumps or motors, nor does it need to extract air from parts that do not need to be dusted. This can reduce energy consumption and thus reduce production costs.

[0039] Furthermore, the wetted sponge tray 7 in this invention can be detached from the outside of the plug sleeve 22, making it easy to replace the wetted sponge tray 7 that has absorbed dust, so as to ensure the dust absorption effect of the wetted sponge tray 7.

[0040] It should be noted that the suction tube 5 in this invention should be a flexible spiral tube or a spring compression tube, etc., which can be elastically contracted to ensure the movement of the suction head 4 inside the grinding box 1.

[0041] The side of the water filling pipe 8 facing the wetted sponge disc 7 is fixedly provided with a water injection pipe 23 that communicates with the water spray hole 32. The water injection pipe 23 is inserted into the interior of the wetted sponge disc 7, and the surface of the water injection pipe 23 is provided with a water injection hole 24 that communicates with its interior. The end of the water injection pipe 23 away from the water filling pipe 8 is a pointed cone shape.

[0042] In actual operation, the water injection pipe 23 is inserted into the interior of the wet sponge tray 7, which serves to fix and limit the position of the wet sponge tray 7, so that the wet sponge tray 7 can rotate stably in the vertical plane with the water filling pipe 8. This allows different parts of the wet sponge tray 7 to contact the opening of the dust collection box 6, preventing a certain part of the wet sponge tray 7 from always being in the position corresponding to the opening of the dust collection box 6 and becoming saturated with adsorption, thus avoiding a reduction in the dust removal effect of the wet sponge tray 7.

[0043] Furthermore, the water injection pipe 23 extends into the interior of the soaking sponge plate 7, and the water injection pipe 23 is provided with a water injection hole 24, which can spray water directly into the interior of the soaking sponge plate 7, instead of allowing water to penetrate from the surface of the soaking sponge plate 7 into the interior of the soaking sponge plate 7. This not only wets the soaking sponge plate 7 more quickly, but also sprays it more evenly.

[0044] In order to enable the hollow column 9 to move back and forth along its axis, the inner wall of the first water tank 12 is fixedly provided with a compression plate 29, and when the hollow column 9 passes the surface of the compression plate 29, the compression spring inside the hollow column 9 is in a compressed state.

[0045] Specifically, when the hollow column 9 passes through the extrusion plate 29 inside the first water tank 12, the extrusion plate 29 will extrude the end of the hollow column 9 away from the insertion sleeve 22, causing the hollow column 9 to move towards the insertion sleeve 22. When the hollow column 9 moves to the position where it is separated from the surface of the extrusion plate 29, the hollow column 9 will move away from the insertion sleeve 22 under the action of the compression spring fixed thereto.

[0046] A hollow ring 18 is provided around the first drive motor 19 to cover it. The hollow ring 18 has an annular cavity inside. A water supply pipe 13 is provided at the bottom of the hollow ring 18. A water filling component is provided inside the first water tank 12 to fill the water supply pipe 13 with water. A downwardly inclined drain pipe 25 is provided on the water supply pipe 13 near the dust collection box 6. A one-way valve is provided inside the drain pipe 25 and on the water supply pipe 13. The one-way valve on the water supply pipe 13 is located below the inner port of the drain pipe 25.

[0047] In actual operation, when the water filling component fills the water supply pipe 13 with water, the water entering the water supply pipe 13 will enter the hollow ring 18. The hollow ring 18 will transfer the temperature of the cold water to the first drive motor 19, thereby cooling the first drive motor 19. When the water filling component stops filling the water supply pipe 13, the water that originally entered the hollow ring 18 will pass through the water supply pipe 13 into the drain pipe 25 and be discharged from the drain pipe 25. Each time the water filling component fills the hollow ring 18 with water, it can cool the first drive motor 19. The water that has entered the hollow ring 18 with a slightly increased temperature will be discharged back into the first water tank 12 from the drain pipe 25, realizing the effect of "circulating water cooling", thus achieving a better cooling effect on the first drive motor 19.

[0048] Specifically, the water filling component includes an airbag 27, which is fixedly connected to the inner wall of the first water tank 12. The airbag 27 is internally connected to the water supply pipe 13. The airbag 27 has a water inlet 36, and a one-way valve is provided inside the water inlet 36. When the hollow column 9 passes through the airbag 27, the airbag 27 is in a compressed state.

[0049] During the rotation of the hollow column 9, it will pass over the airbag component 27 on the inner wall of the first water tank 12. The hollow column 9 will then press against the surface of the airbag component 27. The water inside the airbag component 27 will enter the interior of the hollow ring 18 through the water supply pipe 13, which will cool down the first drive motor 19. When the hollow column 9 moves to the position where it is separated from the airbag component 27, the airbag component 27 will expand again under its own elasticity and absorb water. The water will enter the interior of the airbag component 27 through the water inlet 36. When the airbag component 27 is squeezed by the hollow column 9 again, the water inside it will enter the interior of the hollow ring 18 again through the water supply pipe 13.

[0050] Furthermore, the hollow column 9 can stir the water inside the first water tank 12 as it rotates with the water filling pipe 8, thereby dissipating the heat from the water sprayed from the drain pipe 25 and cooling it again, thus avoiding affecting the heat dissipation of the first drive motor 19.

[0051] It is worth mentioning that the airbag component 27 in this invention is preferably an arc-shaped structure with the same moving trajectory as the hollow column 9, which makes the crushing path of the hollow column 9 on the airbag component 27 longer, and the airbag component 27 can store more water, so that the water inside the airbag component 27 is enough to fill the annular cavity inside the hollow ring 18, thereby improving the cooling effect on the first drive motor 19. In addition, the first water tank 12 can be connected to a circulating cold water mechanism so that the water inside the first water tank 12 is always kept at a low temperature.

[0052] The hollow column 9 is rotatably connected to a sleeve 10, which passes over the surface of the airbag component 27 as the hollow column 9 moves.

[0053] The sleeve 10 can rotate when passing over the surface of the airbag component 27, thereby avoiding large frictional resistance with the airbag component 27 and preventing the hollow column 9 from dragging the surface of the airbag component 27 and causing it to break when passing over the airbag component 27.

[0054] The hollow column 9 is located on the periphery of the wetted sponge disc 7, and when the hollow column 9 moves toward the insertion sleeve 22, it squeezes the outer periphery of the wetted sponge disc 7.

[0055] Specifically, since the extrusion plate 29 is located near the bottom of the wet sponge tray 7, the hollow column 9 will squeeze the outer periphery of the wet sponge tray 7 near the bottom edge of the wet sponge tray 7. As the water absorbed on the wet sponge tray 7 will sink to the bottom of the wet sponge tray 7 under gravity, the extrusion of the hollow column 9 on the side of the wet sponge tray 7 near the bottom can squeeze off the supersaturated water absorbed at the bottom of the wet sponge tray 7 and let it fall into the first water tank 12 for recycling. This also prevents the saturated part of the wet sponge tray 7 from affecting the air discharge inside the dust collection box 6, and prevents the bottom of the wet sponge tray 7 from becoming too heavy due to water settling, thus preventing the wet sponge tray 7 from being pulled downward and deformed. It also prevents the adsorption holes on the wet sponge tray 7 from becoming blocked or enlarged after deformation, which would affect the adsorption effect on dust.

[0056] The top of the hollow ring 18 is fixedly connected to one end of the buffer tube 17, and the other end of the buffer tube 17 extends out of the dust collection box 6.

[0057] The buffer tube 17 allows excess water entering the hollow ring 18 to be stored inside the buffer tube 17, thereby preventing excessive water from exerting an outward force on the hollow ring 18 and thus avoiding cracks or even bursting of the hollow ring 18 after long-term use, thus improving production safety.

[0058] In order to simultaneously cool down the second drive motor 21, the top of the dust collection box 6 is provided with a second water tank 16, and the bottom of the second water tank 16 is provided with a recess 34 for accommodating the second drive motor 21. The top end of the buffer tube 17 extends into the interior of the second water tank 16 and is inclined toward the second drive motor 21. A return hole 20 is provided on the buffer tube 17 near the bottom of the second water tank 16, and a one-way valve is provided inside the return hole 20.

[0059] In practical applications, when the water sprayed from the buffer pipe 17 falls at the bottom of the second water tank 16 and the position corresponding to the second drive motor 21, the temperature of the cold water will be transferred to the second drive motor 21 through the second water tank 16, which will cool the second drive motor 21. The water that falls to the bottom of the second water tank 16 will enter the water supply pipe 13 again through the return hole 20, and then enter the first water tank 12 through the drain pipe 25, completing a cycle.

[0060] It should be noted that both the hollow ring 18 and the second water tank 16 should be made of materials with good thermal conductivity, so as to effectively transfer the temperature of the cold water to the first drive motor 19 and the second drive motor 21.

[0061] The shaft of the second drive motor 21 is provided with a limiting protrusion 28, and the inner wall of the plug sleeve 22 is provided with a limiting groove 35 that matches the limiting protrusion 28.

[0062] The setting of the limiting protrusion 28 and the limiting groove 35 enables the second drive motor 21 to drive the rotation of the plug sleeve 22, thereby driving the rotation of the water filling pipe 8 and the hollow column 9. Even if the hollow column 9 is subjected to the resistance of the airbag component 27 and the extrusion plate 29, the rotation of the plug sleeve 22 can still be achieved.

[0063] Working principle: In actual operation, the workpiece to be processed can be placed inside the grinding box 1. The mechanical cantilever 2 can drive the grinding head 3 to move in various positions inside the grinding box 1, thereby achieving all-round grinding of the workpiece surface and edges. During the grinding process, the turbine 15 rotates under the drive of the first drive motor 19 and generates negative pressure, so that the dust generated by grinding inside the grinding box 1 will enter the suction pipe 5 through the suction head 4 and then enter the inside of the suction box 6 for collection. The extracted air will pass through the filter screen 14 inside the suction box 6 and be discharged from the opening of the suction box 6. Since the filter screen 14 can only filter particles of a certain size, in actual application, some small particles smaller than the pore size of the filter screen 14 will also be discharged from the opening of the suction box 6. The wetted sponge plate 7 can adsorb these small particles, thereby making the air discharged from the wetted sponge plate 7 cleaner and less polluting to the environment.

[0064] Meanwhile, to ensure the soaked sponge disc 7 remains moist, the present invention includes a water-filling pipe 8 and a hollow column 9. When the hollow column 9 passes through the first water tank 12, it moves back and forth within the tank. When the hollow column 9 first moves towards the insertion sleeve 22, air inside it enters the water-filling pipe 8 through the water outlet 31 and exits through the spray nozzle 32. Conversely, when the hollow column 9 moves away from the insertion sleeve 22... When the device moves, the water inside the first water tank 12 will enter the hollow column 9 through the water suction hole 30 for storage. When the hollow column 9 moves closer to the plug sleeve 22, the water inside the hollow column 9 will enter the water filling pipe 8 through the water outlet 31 and be sprayed from the water spray hole 32 on the water filling pipe 8 onto the surface of the wet sponge plate 7 and absorbed by the wet sponge plate 7, thereby keeping the wet sponge plate 7 moist, which facilitates further purification of the air sprayed from the opening of the dust collection box 6.

[0065] The dust suction head 4 of the present invention is located at the free end of the mechanical cantilever 2 near the grinding head 3. Thus, the dust suction head 4 can move with the grinding head 3 to achieve more precise dust suction. Compared with traditional large-area air extraction and dust removal, the present invention only removes dust from the part that is being ground and generates dust. Therefore, it does not need to use energy-consuming components such as high-power air pumps or motors, nor does it need to extract air from parts that do not need to be dusted. This can reduce energy consumption and thus reduce production costs.
