A controller is fixed on a workbench, and the controller is electrically connected to the trigger button, two hydraulic cylinders, a driving motor, a moving motor, a plurality of protective gas nozzles, and a rotating structure.

[0006] When the parts need to be polished, the staff puts the parts on the upper surface of the mobile table and puts them between the first clamping plate and the second clamping plate. Then the staff controls the two hydraulic cylinders to contract through the controller, and the two hydraulic cylinders drive the lifting plate to descend, and the lifting plate drives the rack, two support columns, protective cover, drive motor, grinding wheel, cleaning brush, and trigger button to descend until the elastic rubber on the bottom of the protective cover is pressed against the surface of the workbench. The descent of the rack drives the linkage gear to rotate, the linkage gear drives the active roller to rotate, the active roller drives the driven roller and the conveyor belt to rotate, and the conveyor belt drives the fixed block, the sliding plate, and the second clamping plate to move toward the first clamping plate, so that the second clamping plate and the first clamping plate clamp the parts.

[0007] When the elastic rubber on the bottom of the protective cover is pressed against the surface of the workbench, the protective cover covers the moving groove. At this time, the grinding wheel and the cleaning brush are in close contact with the parts. At this time, the trigger button is pressed by the surface of the workbench. The trigger button sends a signal to the controller. The controller controls the two hydraulic cylinders to stop, controls the drive motor and several protective gas nozzles to start, and controls the moving motor to reciprocate once. The drive motor drives the grinding wheel and the active pulley to rotate, and the grinding wheel grinds the parts. At the same time, the active pulley drives the driven pulley and the cleaning brush to rotate through the linkage belt, and the cleaning brush cleans the dust generated by the grinding of the surface of the parts. At the same time, several protective gas nozzles spray the protective gas in the gas tank into the protective cover to protect the grinding process of the parts and clean the dust generated by the grinding of the surface of the parts. The moving motor drives the screw to reciprocate once, and the screw drives the moving table, the second clamping plate, the first clamping plate, the parts, and the linkage gear to reciprocate, and the upper surface of the parts is polished and cleaned by the grinding wheel and the cleaning brush. By setting a lifting block and a telescopic spring, elastic contact is achieved, so that the grinding wheel, the cleaning brush and the parts can be protected.

[0008] After the mobile motor rotates back and forth once, the controller controls the two hydraulic cylinders to extend, and the two hydraulic cylinders drive the rack, two support columns, protective cover, drive motor, grinding wheel, cleaning brush, and trigger button to rise until the trigger button is separated from the workbench. At this time, a gap is generated between the protective cover and the workbench. The trigger button sends a signal to the controller, and the controller controls the two hydraulic cylinders, drive motor, and several protective gas nozzles to close, and controls the fan to start for a period of time. The fan drives the outside air through the gap between the protective cover and the workbench, the upper surface of the workbench, the moving slot, the filter, and the fan to be discharged to the outside again. Among them, the airflow brings the dust on the upper surface of the workbench into the moving slot, and the filter blocks the dust in the airflow. When the fan stops, the controller controls the two hydraulic cylinders to extend to the initial length. The two hydraulic cylinders drive the rack, two support columns, protective cover, drive motor, grinding wheel, cleaning brush, and trigger button to rise to the initial position. The rising rack drives the linkage gear to rotate, and the linkage gear drives the active roller to rotate. The active roller drives the driven roller and the conveyor belt to rotate. The conveyor belt drives the fixed block, the sliding plate, and the second clamping plate to move away from the first clamping plate, so that the second clamping plate and the first clamping plate release the parts. Then the staff replaces the parts and repeats the grinding work. By setting an observation window, the staff can observe the grinding process of the parts. The present invention can realize automatic clamping, reciprocating grinding, cleaning, gas protection, and release of parts, which improves the automation of the grinding equipment, saves time and effort, and improves the grinding efficiency of parts. By setting a rotating structure, the workbench can be rotated, which is more convenient.

[0009] Furthermore, rubber pads are provided on the opposite sides of the first clamping plate and the second clamping plate.

[0010] By providing rubber pads, components can be protected.

[0011] Furthermore, it includes a fixing sleeve and a first fixing screw. The protective cover is slidably connected to the two support columns, and its sliding direction is vertically arranged. The fixing sleeve is set on the support column, located above the protective cover, and fixedly connected to the protective cover. The first fixing screw passes through the fixing sleeve horizontally and is connected to the support column, and the first fixing screw is threadedly connected to the fixing sleeve.

[0012] By setting the height of the protective cover to be adjustable, it can adapt to parts of different heights.

[0013] Furthermore, it includes a sliding groove, a sliding block, and a second fixing screw. The sliding groove is a long T-shaped groove, which is arranged on the bottom surface of the lifting plate, and the sliding groove is perpendicular to the axis of the linkage gear. The sliding block is slidably arranged in the sliding groove and connected to the upper end of the rack. The second fixing screw passes through the sliding block upward and is connected to the inner surface of the sliding groove, and the second fixing screw is threadedly connected to the sliding block.

[0014] When facing different types of parts, the staff first controls the trigger button to close through the controller, and then loosens the first fixing screw and the second fixing screw, and then moves the rack and the sliding block to separate the rack from the linkage gear, and then squeezes the first clamping plate and the second clamping plate to make the first clamping plate and the second clamping plate close to each other and contact the parts. Then the two hydraulic cylinders are controlled by the controller to contract, and the two hydraulic cylinders drive the lifting plate to descend, and the lifting plate drives the rack, two support columns, protective cover, drive motor, grinding wheel, cleaning brush, and trigger button to descend until the grinding wheel contacts the parts, and the elastic rubber on the bottom of the protective cover contacts the workbench. Then the staff tightens the first fixing screw to fix the fixing sleeve, protective cover and the two support columns. After that, the staff moves the rack and the sliding block to make the rack mesh with the linkage gear, and then the staff tightens the second fixing screw to fix the rack with the lifting plate. Then the trigger button is controlled by the controller to open. At this time, the elastic rubber on the bottom of the protective cover is only in contact with the workbench, the grinding wheel is only in contact with the parts, and the first clamping plate and the second clamping plate are only in contact with the parts. Therefore, when the elastic rubber on the bottom of the protective cover is pressed against the workbench during the grinding process, the grinding wheel and the cleaning brush can be tightly attached to the parts, and the rubber pads on the surface of the first clamping plate and the second clamping plate can tightly clamp the parts. By setting the distance between the first clamping plate and the second clamping plate to be adjustable, parts of different widths can be accommodated. By setting the distance between the first clamping plate and the second clamping plate to be adjustable, the height of the protective cover to be adjustable, and the trigger button, different parts can be adapted and polished, which is very convenient and quick, and improves the efficiency of polishing parts.

[0015] Furthermore, the rack is cylindrical, and its axis is vertically arranged. The upper end of the rack is rotatably connected to the sliding block, and the rotation axis of the rack coincides with the axis of the rack.

[0016] When the linkage gear moves laterally, the linkage gear drives the rack to rotate, thereby reducing the friction between the rack and the linkage gear.

[0017] Furthermore, it comprises two elastic telescopic pipes, which are sleeved on the screw rod and respectively located at two sides of the moving platform, and the two elastic telescopic pipes cover the screw rod outside the moving platform.

[0018] By providing two elastic telescopic pipes, the screw can be protected to prevent dust from jamming the screw.

[0019] Furthermore, it includes a discharge channel, which is obliquely arranged inside the workbench, with its upper end connected to the bottom of the movable groove and the lower end connected to the outer side of the workbench. An electric valve is arranged in the discharge channel, and the electric valve is electrically connected to the controller.

[0020] When there is too much dust in the mobile tank, the staff starts the electric valve through the controller to discharge the dust in the mobile tank through the discharge channel.

[0021] Furthermore, the knocking rod is perpendicular to the screw rod and is arranged in the movable groove, one end of the knocking rod is fixedly connected to the screw rod and the other end is in contact with the filter screen.

[0022] When the moving motor drives the screw to rotate, the screw drives the knocking rod to rotate and knock on the filter screen, so that the dust on the filter screen falls off, preventing the dust from clogging the filter screen.

[0023] Furthermore, the gas tank contains nitrogen.

[0024] Set the protective gas to nitrogen. Since the density of nitrogen is lower than that of air, the nitrogen will rise into the protective cover and move up and down with the protective cover. When the parts are being polished, there is still nitrogen left over from the last polishing of the parts in the protective cover, which can better protect the parts during the polishing process.

[0025] A grinding method for a grinding device with a rotating structure for automobile parts: When facing different types of parts, the staff first controls the trigger button to close through a controller, and then the staff first loosens the first fixing screw and the second fixing screw, and then moves the rack and the sliding block to separate the rack from the linkage gear, and then squeezes the first clamping plate and the second clamping plate to make the first clamping plate and the second clamping plate approach each other and contact the parts. Then the controller controls the two hydraulic cylinders to contract, and the two hydraulic cylinders drive the lifting plate to descend, and the lifting plate drives the rack, two support columns, a protective cover, a driving motor, a grinding wheel, a cleaning brush, and the trigger button to descend until the grinding wheel contacts the parts, and the elastic rubber on the bottom of the protective cover contacts the workbench. Then the staff tightens the first fixing screw to fix the fixing sleeve, the protective cover and the two support columns. After that, the staff moves the rack and the sliding block to mesh the rack with the linkage gear, and then the staff tightens the second fixing screw to fix the rack with the lifting plate. Then the trigger button is controlled to open through the controller.

The moving motor 29 drives the screw 21 to reciprocate once, and the screw 21 drives the moving platform 2, the second clamping plate 28, the first clamping plate 24, the parts, and the linkage gear 212 to reciprocate, and the upper surface of the parts is polished and cleaned by the grinding wheel 411 and the cleaning brush. By setting the lifting block 46 and the telescopic spring 44, elastic contact is achieved, and the grinding wheel 411, the cleaning brush, and the parts can be protected.

[0036] After the moving motor 29 rotates back and forth once, the controller controls the two hydraulic cylinders 3 to extend, and the two hydraulic cylinders 3 drive the rack 5, the two support columns 41, the protective cover 4, the drive motor 45, the grinding wheel 411, the cleaning brush, and the trigger button 410 to rise until the trigger button 410 is separated from the workbench 1. At this time, a gap is generated between the protective cover 4 and the workbench 1. The trigger button 410 sends a signal to the controller, and the controller controls the two hydraulic cylinders 3, the drive motor 45, and several protective gas nozzles 47 to close, and controls the fan to start for a period of time. The fan drives the outside air to pass through the gap between the protective cover 4 and the workbench 1, the upper surface of the workbench 1, the moving groove 11, the filter 210, and the fan to be discharged to the outside again. Among them, the airflow brings the dust on the upper surface of the workbench 1 into the moving groove 11, and the filter 210 blocks the dust in the airflow. When the fan stops, the controller controls the two hydraulic cylinders 3 to extend to the initial length, and the two hydraulic cylinders 3 drive the rack 5, the two support columns 41, the protective cover 4, the drive motor 45, the grinding wheel 411, the cleaning brush, and the trigger button 410 to rise to the initial position. The rack 5 rises to drive the linkage gear 212 to rotate, and the linkage gear 212 drives the active roller 22 to rotate, and the active roller 22 drives the driven roller 26 and the conveyor belt 23 to rotate. The conveyor belt 23 drives the fixed block 25, the sliding plate 27, and the second clamping plate 28 to move away from the first clamping plate 24, so that the second clamping plate 28 and the first clamping plate 24 release the parts. Then the staff replaces the parts and repeats the grinding work. By setting an observation window, the staff can observe the grinding process of the parts.

By providing a rotating structure, the workbench 1 can be rotated, which is more convenient.

[0037] Rubber pads are provided on opposite sides of the first clamping plate 24 and the second clamping plate 28 .

[0038] By providing rubber pads, components can be protected.

[0039] It includes a fixing sleeve 43 and a first fixing screw 42. The protective cover 4 is slidably connected to the two support columns 41, and its sliding direction is vertically arranged. The fixing sleeve 43 is sleeved on the support columns 41, located above the protective cover 4, and is fixedly connected to the protective cover 4. The first fixing screw 42 passes through the fixing sleeve 43 horizontally and is connected to the support column 41. The first fixing screw 42 is threadedly connected to the fixing sleeve 43.

[0040] By arranging the height of the protective cover 4 to be adjustable, it can adapt to components of different heights.

[0041] It includes a sliding groove, a sliding block 51, and a second fixing screw 52. The sliding groove is a long T-shaped groove, which is arranged on the bottom surface of the lifting plate 31, and the sliding groove is perpendicular to the axis of the linkage gear 212. The sliding block 51 is slidably arranged in the sliding groove and connected to the upper end of the rack 5. The second fixing screw 52 passes through the sliding block 51 upwards and is connected to the inner surface of the sliding groove. The second fixing screw 52 is threadedly connected to the sliding block 51.

[0042] When facing different types of parts, the staff first controls the trigger button 410 to close through the controller, and then loosens the first fixing screw 42 and the second fixing screw 52, ​​and then moves the rack 5 and the sliding block 51 to separate the rack 5 from the linkage gear 212, and then squeezes the first clamping plate 24 and the second clamping plate 28 to make the first clamping plate 24 and the second clamping plate 28 close to each other and contact the parts. Then the two hydraulic cylinders 3 are controlled to contract through the controller, and the two hydraulic cylinders 3 drive the lifting plate 31 to descend, and the lifting plate 31 drives the rack 5, the two support columns 41, the protective cover 4, the drive motor 45, the grinding wheel 411, the cleaning brush, and the trigger button 410 to descend until the grinding wheel 411 contacts the parts, and the elastic rubber on the bottom of the protective cover 4 contacts the workbench 1. Then the staff tightens the first fixing screw 42 to fix the fixing sleeve 43, the protective cover 4 and the two support columns 41. After that, the staff moves the rack 5 and the sliding block 51 to make the rack 5 mesh with the linkage gear 212, and then tightens the second fixing screw 52 to fix the rack 5 to the lifting plate 31. Then the trigger button 410 is turned on by the controller. At this time, the elastic rubber on the bottom of the protective cover 4 is only in contact with the workbench 1, the grinding wheel 411 is only in contact with the parts, and the first clamping plate 24 and the second clamping plate 28 are only in contact with the parts, so that when the elastic rubber on the bottom of the protective cover 4 is pressed against the workbench 1 during the grinding process, the grinding wheel 411 and the cleaning brush can be tightly attached to the parts, and the rubber pads on the surfaces of the first clamping plate 24 and the second clamping plate 28 can tightly clamp the parts. By setting the distance between the first clamping plate 24 and the second clamping plate 28 to be adjustable, it can adapt to parts of different widths. By setting the distance between the first clamping plate 24 and the second clamping plate 28 to be adjustable, the height of the protective cover 4 to be adjustable, and the trigger button 410, different parts can be adapted and polished, which is very convenient and quick, and improves the polishing efficiency of the parts.

[0043] The rack 5 is cylindrical, and its axis is vertically arranged. The upper end of the rack 5 is rotatably connected to the sliding block 51 , and the rotation axis of the rack 5 coincides with the axis of the rack 5 .

[0044] When the linkage gear 212 moves laterally, the linkage gear 212 drives the rack 5 to rotate, thereby reducing the friction between the rack 5 and the linkage gear 212 .

[0045] The two elastic telescopic pipes are sleeved on the screw rod 21 and are respectively located on both sides of the moving platform 2 . The two elastic telescopic pipes cover the screw rod 21 outside the moving platform 2 .

[0046] By providing two elastic telescopic pipes, the screw rod 21 can be protected to prevent dust from blocking the screw rod 21 .

[0047] The discharge channel 12 is obliquely arranged inside the workbench 1, with its upper end connected to the bottom of the movable groove 11 and its lower end connected to the outer side of the workbench 1. An electric valve 13 is arranged in the discharge channel 12, and the electric valve 13 is electrically connected to the controller.

[0048] When there is too much dust in the moving tank 11 , the staff starts the electric valve 13 through the controller to discharge the dust in the moving tank 11 through the discharge channel 12 .

[0049] The knocking rod 211 is perpendicular to the screw rod 21 and is arranged in the moving groove 11 , one end of the knocking rod 211 is fixedly connected to the screw rod 21 and the other end of the knocking rod 211 is in contact with the filter screen 210 .

[0050] When the moving motor 29 drives the screw rod 21 to rotate, the screw rod 21 drives the knocking rod 211 to rotate and knock the filter screen 210, so that the dust on the filter screen 210 falls off, thereby preventing the dust from clogging the filter screen 210.

[0051] The gas tank contains nitrogen.

[0052] The protective gas is set to nitrogen. Since the density of nitrogen is lower than that of air, the nitrogen will rise into the protective cover 4 and move up and down with the protective cover 4. When the parts are polished, there is still nitrogen retained from the last polishing of the parts in the protective cover 4, so that the polishing process of the parts can be better protected.

[0053] Working process: When it is necessary to grind the parts, the staff puts the parts on the upper surface of the mobile table 2, between the first clamping plate 24 and the second clamping plate 28. Then the staff controls the two hydraulic cylinders 3 to contract through the controller, and the two hydraulic cylinders 3 drive the lifting plate 31 to descend, and the lifting plate 31 drives the rack 5, the two support columns 41, the protective cover 4, the drive motor 45, the grinding wheel 411, the cleaning brush, and the trigger button 410 to descend until the elastic rubber on the bottom of the protective cover 4 is pressed against the surface of the workbench 1. The descent of the rack 5 drives the linkage gear 212 to rotate, the linkage gear 212 drives the active roller 22 to rotate, the active roller 22 drives the driven roller 26 and the conveyor belt 23 to rotate, and the conveyor belt 23 drives the fixed block 25, the sliding plate 27, and the second clamping plate 28 to move toward the first clamping plate 24, so that the second clamping plate 28 and the first clamping plate 24 clamp the parts.

[0054] When the elastic rubber on the bottom of the protective cover 4 is pressed against the surface of the workbench 1, the protective cover 4 covers the movable groove 11. At this time, the grinding wheel 411 and the cleaning brush are in close contact with the parts. At this time, the trigger button 410 is pressed by the surface of the workbench 1. The trigger button 410 sends a signal to the controller. The controller controls the two hydraulic cylinders 3 to stop, controls the drive motor 45 and several protective gas nozzles 47 to start, and controls the mobile motor 29 to reciprocate once. The drive motor 45 drives the grinding wheel 411 and the driving pulley 48 to rotate, and the grinding wheel 411 grinds the parts. At the same time, the driving pulley 48 drives the driven pulley and the cleaning brush to rotate through the linkage belt 49, and the cleaning brush cleans the dust generated by the grinding of the parts. At the same time, several protective gas nozzles 47 spray the nitrogen in the gas tank into the protective cover 4 to protect the grinding process of the parts and clean the dust generated by the grinding of the parts. The moving motor 29 drives the screw 21 to rotate back and forth once, and the screw 21 drives the moving platform 2, the second clamping plate 28, the first clamping plate 24, the parts, and the linkage gear 212 to move back and forth, and the upper surface of the parts is polished and cleaned by the grinding wheel 411 and the cleaning brush. At the same time, the screw 21 drives the knocking rod 211 to rotate and knock the filter 210, so that the dust on the filter 210 falls off to prevent the dust from clogging the filter 210. At the same time, when the linkage gear 212 moves horizontally, the linkage gear 212 drives the rack 5 to rotate, thereby reducing the friction between the rack 5 and the linkage gear 212. By setting the lifting block 46 and the telescopic spring 44, elastic contact is achieved, which can protect the grinding wheel 411, the cleaning brush, and the parts.

The rack 5 rises to drive the linkage gear 212 to rotate, and the linkage gear 212 drives the active roller 22 to rotate, and the active roller 22 drives the driven roller 26 and the conveyor belt 23 to rotate. The conveyor belt 23 drives the fixed block 25, the sliding plate 27, and the second clamping plate 28 to move away from the first clamping plate 24, so that the second clamping plate 28 and the first clamping plate 24 release the parts. Then the staff replaces the parts and repeats the grinding work. By setting an observation window, the staff can observe the grinding process of the parts. The present invention can realize the automatic clamping, reciprocating grinding, cleaning, gas protection, and release of the parts, improves the automation of the grinding equipment, saves time and effort, and improves the grinding efficiency of the parts.

[0056] When facing different types of parts, the staff first controls the trigger button 410 to close through the controller, and then loosens the first fixing screw 42 and the second fixing screw 52, ​​and then moves the rack 5 and the sliding block 51 to separate the rack 5 from the linkage gear 212, and then squeezes the first clamping plate 24 and the second clamping plate 28 to make the first clamping plate 24 and the second clamping plate 28 close to each other and contact the parts.
