Description

Technical Field

[0001] This invention relates to the field of automotive cover processing technology, specifically to an adaptively adjustable grinding device for automotive covers and its usage method. Background Technology

[0002] Automotive covers are an important component in the automotive body structure, typically used to cover certain areas inside or outside the vehicle, serving to protect, decorate, or conceal the internal structure. Circular covers, as one shape, are commonly used for vehicle logo covers, fuel filler caps, etc. In the automotive manufacturing industry, the surface quality of automotive covers directly affects the overall appearance and performance of the vehicle. During the manufacturing process, grinding equipment is used to polish automotive covers to improve processing precision and surface quality. A grinding belt slides across the surface of the automotive cover, thus polishing it.

[0003] In existing automotive cover grinding equipment, before grinding round automotive covers, the covers are clamped and fixed on the top of a turntable for rotation and grinding. After grinding, the covered covers need to be manually released from the top of the turntable by the operator. Manual fixing or loosening can easily affect the efficiency of placing and picking up the covers, thus affecting the work efficiency of grinding batches of automotive covers. At the same time, when the grinding belt is pressed against the top of the cover, the protruding shape of the cover makes it difficult for the grinding belt to adhere tightly to the top of the cover, affecting the grinding effect of the grinding belt on the cover. Therefore, improvements are needed.

[0004] Based on this, the present invention designs an adaptive adjustment grinding device for automotive cover plates and its usage method to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an adaptively adjustable grinding device for automobile covers and its method of use, in order to solve the problem mentioned in the background art that, in the existing grinding devices for automobile covers, before grinding a round automobile cover, the round automobile cover is clamped and fixed on the top of the turntable for rotating grinding. After grinding, the automobile cover needs to be manually loosened from the top of the turntable by the operator. Manual fixing or loosening can easily affect the efficiency of placing and picking up the automobile cover, thereby affecting the work efficiency of grinding batches of automobile covers. At the same time, when the grinding belt is pressed against the top of the automobile cover, the shape of the automobile cover has a protrusion, which makes it difficult for the grinding belt to be pressed firmly against the top of the automobile cover, affecting the grinding effect of the grinding belt on the automobile cover.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An adaptive grinding device for automotive cover plates includes a base, a rotating motor fixedly installed at the bottom of the base, a conveyor turntable rotatably mounted on the top of the base via bearings, three cover plate bodies on the top of the conveyor turntable, an arc-shaped pressure block fixedly installed at the center of the top of the base on one side of the conveyor turntable, electric lifting seats symmetrically fixedly installed on both sides of the base, a grinding mechanism fixedly installed between the telescopic ends of the two electric lifting seats, and a clamping mechanism symmetrically fixedly installed on the top of the grinding mechanism.

[0009] As a further embodiment of the present invention, a mounting circular groove is provided at the center position between each group of rectangular grooves on the top of the conveyor turntable. The bottom of the mounting circular groove is connected to a mounting groove one, and one side of the mounting groove one is connected to a mounting groove two. A movable slide rod is slidably installed inside the mounting groove two. One end of the two movable slide rods extends through the mounting groove two to the outside of the conveyor turntable and is fixedly installed with a semi-circular pressure block. The semi-circular pressure block and the inner side of the arc-shaped pressure block are closely aligned. A limit plate is fixedly installed at one end of the movable slide rod inside the mounting groove two. A return spring is sleeved on the surface of the movable slide rod inside the mounting groove two.

[0010] As a further embodiment of the present invention, a fixing plate is fixedly installed at the middle height position inside the mounting groove, a trapezoidal slider is slidably installed inside the mounting groove, and the trapezoidal slider slides close to the top of the fixing plate. A limiting groove is symmetrically provided on one side of the trapezoidal slider. Mounting slide posts are symmetrically slidably installed through the fixing plate, and the limiting groove slides on the surface of the mounting slide posts. The bottom ends of the two mounting slide posts extend through the fixing plate to the bottom of the mounting groove and are fixedly connected to a reset pressure plate.

[0011] As a further embodiment of the present invention, a downward pressure spring is sleeved on the surface of the mounting slide column located between the fixed plate and the reset pressure plate. The top ends of the two mounting slide columns pass through the fixed plate and the trapezoidal slider and are fixedly connected to a trapezoidal pressure block, and the trapezoidal pressure block is in contact with the trapezoidal slider. A top plate is fixedly connected to the top of the trapezoidal pressure block, and the top plate is snapped into the inside of the mounting groove.

[0012] As a further embodiment of the present invention, the grinding mechanism includes a mounting frame, and grinding rollers are rotatably mounted on both ends of the mounting frame via bearings. Grinding belts are sleeved on the surfaces of the two grinding rollers, and the bottom of the grinding belts is in close contact with the cover plate body. One end of one of the grinding rollers passes through the mounting frame and is fixedly connected to a transmission gear. A grinding motor is fixedly mounted on one side of the top of the mounting frame, and a drive gear is fixedly connected to the output end of the grinding motor, and the drive gear meshes with the transmission gear.

[0013] As a further embodiment of the present invention, the clamping mechanism includes a concave frame, three clamping rods are slidably connected through the top of the concave frame, a fixed frame is fixedly connected to the bottom of the three clamping rods, and a connecting strip is fixedly connected through the top of the three clamping rods. A clamping spring is sleeved on the surface of the clamping rods located between the fixed frame and the top of the concave frame. A clamping roller is rotatably mounted on the bottom of the fixed frame via a rotating shaft, and the clamping roller is in close contact with the top of the grinding belt. Limiting grooves are symmetrically provided on both sides of the concave frame, and the fixed frame is slidably connected through the limiting grooves on both sides.

[0014] A method of using an adaptively adjustable grinding machine for automotive cover plates, the method comprising the following steps: The rotating motor is started, driving the rotating disc to rotate. This causes the pins to intermittently engage with the intermittent slots on the surface of the intermittent rotating disc. The intermittent rotating disc drives the conveyor disc to rotate intermittently on the top of the base. During the rotation of the conveyor disc, the cover plate body is engaged between four corresponding clamping rollers. The clamping rollers push the moving slider to slide on the corresponding mounting rod surface, compressing the clamping springs and deforming them. The springs then return to their original position, clamping and fixing the cover plate body between the four clamping rollers. The conveyor disc is then rotated to move the cover plate body to the bottom of the grinding mechanism. The grinding motor is then started, and the transmission mechanism, via the drive gear and the conveyor... The meshing of the moving gear controls the rotation of the grinding roller, causing the grinding belt to move on the top of the cover plate body. At the same time, the electric lifting seat is extended and retracted, driving the grinding mechanism to move downward, so that the grinding belt is pressed against the top of the cover plate body for grinding. When the grinding belt is pressed against the top of the cover plate body, the grinding belt deforms, causing the top of the grinding belt to straighten and lift the pressure roller. This pushes the fixing frame to move upward at the bottom of the concave frame, compressing the pressure spring. Under the rebound of the pressure spring, the fixing frame is pressed downward, so that the pressure roller presses against the top of the grinding belt, ensuring that the grinding belt is taut on the top of the cover plate body for grinding. After the cover plate body is polished, the control turntable rotates to move the cover plate body away from the bottom of the polishing mechanism. During the rotation of the turntable, the semi-circular pressure block moves closer to the arc-shaped pressure block, making the semi-circular pressure block fit tightly against the inner wall of the arc-shaped pressure block. The arc-shaped pressure block pushes and squeezes the semi-circular pressure block, causing the moving slide rod to retract into the second mounting groove. This causes the limiting plate to deform the reset spring inside the second mounting groove. At the same time, the moving slide rod drives the trapezoidal slider to slide inside the first mounting groove. The trapezoidal slider fits tightly against the inclined surface on the opposite side of the trapezoidal pressure block, lifting the trapezoidal pressure block upward. Under the action of the mounting slide column, the reset pressure plate moves upward and approaches the fixed plate, compressing the lower pressure spring between the fixed plate and the reset pressure plate until... The top plate pushes out of the mounting groove, pushing the cover plate body between the four clamping rollers. This facilitates the removal and replacement of the polished cover plate body. The control turntable continues to rotate, moving the semi-circular pressure block away from the arc-shaped pressure block. Under the rebound action of the return spring, the limit plate is lifted and slides back inside the second mounting groove. This causes the moving slide rod to pull the trapezoidal slider to slide at the bottom of the trapezoidal pressure block. Under the rebound action of the downward pressure spring, the downward pressure plate pulls the mounting slide column down inside the limit slide groove until the top plate moves down and is inserted into the mounting groove. This makes it easy to press the unprocessed cover plate body against the mounting groove and insert it between the corresponding clamping rollers, improving the efficiency of polishing a batch of cover plate bodies.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting up a rotating motor, clamping springs, clamping rollers, a return spring, a trapezoidal slider, a downward pressure spring, a top plate, and an arc-shaped pressure block, allows the cover plate body to be placed between the four clamping rollers. The cover plate body lifts the clamping rollers, pushing the movable slider to slide on the surface of the mounting slide rod, compressing the clamping springs and deforming them. Under the rebound action of the clamping springs, the movable slider is lifted, causing the clamping rollers to clamp onto the surface of the cover plate body, thereby clamping and fixing the cover plate body to the top of the conveyor turntable. The rotating motor is started to control the pin to intermittently engage with the intermittent slots on the surface of the intermittent turntable, causing the intermittent turntable to drive the conveyor turntable to rotate intermittently on the top of the base. The cover plate body clamped and fixed to the top of the conveyor turntable is moved to the bottom of the grinding mechanism for grinding. After the cover plate body is ground, the conveyor turntable is controlled to rotate... The cover plate body rotates away from the bottom of the grinding mechanism until the semi-circular pressure block and arc-shaped pressure block corresponding to the ground cover plate body are pressed together. The moving slide rod is squeezed into the second mounting groove, causing the return spring to deform. This pushes the trapezoidal slider to lift the trapezoidal pressure block, causing the top plate to lift the cover plate body. The cover plate body is then pushed out of the four clamping rollers, making it easy to pick up and replace the ground cover plate body. The control of the conveyor turntable continues to rotate, causing the semi-circular pressure block to disengage from the arc-shaped pressure block. Under the rebound of the return spring, the limit plate is lifted, causing the moving slide rod to drive the trapezoidal slider to slide inside the first mounting groove. Under the rebound of the downward pressure spring, the return pressure plate is pressed down. Under the pull of the mounting slide column, the top plate is pressed down and inserted into the mounting circular groove, making the top plate and the conveyor turntable flush, making it easy to press the cover plate body tightly against the top of the conveyor turntable again.

[0016] 2. This invention, by setting up an electric lifting seat, a grinding belt, a clamping spring, and a clamping roller, ensures that when the conveyor turntable drives the cover plate body to rotate to the bottom of the grinding mechanism, the grinding motor is activated to control the drive gear to rotate. Under the meshing action of the drive gear and the transmission gear, the grinding roller is controlled to rotate, causing the grinding belt to rotate on the top of the cover plate body. The electric lifting seat is controlled to retract, bringing the grinding belt closer to the cover plate body. The cover plate body squeezes the grinding belt, causing it to deform. During the deformation process, the top of the grinding belt straightens, squeezing the clamping roller. This causes the clamping roller to move upward inside the concave frame, squeezing and deforming the clamping spring. Under the rebound action of the clamping spring, the fixing frame is pressed down, pressing the clamping roller tightly against the top of the grinding belt. This ensures that the grinding belt is taut between the two grinding rollers, keeping it always close to the top of the cover plate body. This prevents the grinding belt from loosening during the rotation and grinding process on the top of the cover plate body, which would affect the grinding effect of the grinding belt on the cover plate body.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-8 The present invention provides a technical solution: An adaptive adjustment grinding device for automotive cover plates includes a base 1, a rotating motor 2 fixedly installed at the bottom of the base 1, a conveyor turntable 3 rotatably installed on the top of the base 1 via bearings, three cover plate bodies 4 on the top of the conveyor turntable 3, an arc-shaped pressure block 5 fixedly installed at the center of the top of the base 1 on one side of the conveyor turntable 3, electric lifting seats 6 symmetrically fixedly installed on both sides of the base 1, a grinding mechanism 7 fixedly installed between the telescopic ends of the two electric lifting seats 6, and a clamping mechanism 8 symmetrically fixedly installed on the top of the grinding mechanism 7. During operation, the unpolished cover plate body 4 is clamped on the top of the conveyor turntable 3. The rotating motor 2 is started to control the conveyor turntable 3 to rotate intermittently on the top of the base 1, so that the cover plate body 4 rotates to the bottom of the polishing mechanism 7. The polishing mechanism 7 is started to work on the top of the cover plate body 4. The electric lifting seat 6 is controlled to retract so that the polishing mechanism 7 presses against the top of the cover plate body 4 to polish the cover plate body 4 until the cover plate body 4 is polished. Then, the conveyor turntable 3 is controlled to rotate to remove the cover plate body 4 from the top of the polishing mechanism 7. Under the squeezing action of the arc-shaped pressure block 5, the cover plate body 4 is lifted from the top of the conveyor turntable 3 to facilitate the replacement of the polished cover plate body 4. As a further embodiment of the present invention, a rotating disk 201 is fixedly connected to the output end of the rotating motor 2, a dial 202 is fixedly installed on the top of the rotating disk 201, and a round pin 203 is fixedly installed on the rotating disk 201 at the groove of the dial 202. An intermittent turntable 204 is overlapped on the top of the rotating disk 201. Three intermittent slots 205 are provided at equal angles on the surface of the intermittent turntable 204, and the intermittent slots 205 are engaged with the round pin 203. During operation, the rotating motor 2 is started to control the rotating disk 201 to rotate, causing the pin 203 to rotate intermittently and engage with the intermittent slot 205, which in turn pushes the intermittent turntable 204 to drive the transmission turntable 3 to rotate intermittently. At the same time, when the intermittent turntable 204 rotates, the convex edge of the dial 202 is pressed against the concave groove on the surface of the intermittent turntable 204 to limit the movement of the intermittent turntable 204 and ensure that the intermittent turntable 204 rotates continuously.

[0022] As a further embodiment of the present invention, a connecting column 301 is fixedly connected at the center of the bottom of the conveyor turntable 3, and the connecting column 301 is rotatably connected to the top of the base 1 through a bearing. The bottom end of the connecting column 301 passes through the top of the base 1 and is fixedly connected to the intermittent turntable 204. The top of the conveyor turntable 3 is provided with multiple rectangular slots 302, and four rectangular slots 302 are grouped together. Each rectangular slot 302 is fixedly installed with a mounting slide rod 303. A movable slider 304 is slidably connected through the surface of the mounting slide rod 303. A clamping spring 305 is sleeved on the surface of the mounting slide rod 303 located on one side of the movable slider 304. A clamping roller 306 is fixedly installed on the top of the movable slider 304. During operation, the cover plate body 4 is placed between the four corresponding clamping rollers 306, causing the cover plate body 4 to push and lift the clamping rollers 306, which in turn causes the sliding block 304 to slide on the surface of the mounting rod 303. This causes the clamping spring 305 to deform on the surface of the mounting rod 303. Under the rebound action of the clamping spring 305, the clamping rollers 306 are pressed tightly against the surface of the cover plate body 4, thereby clamping and fixing the cover plate body 4 to the top of the conveyor turntable 3. This ensures that the cover plate body 4 will not easily slide on the top of the conveyor turntable 3 during the rotation of the conveyor turntable 3.

[0023] As a further embodiment of the present invention, a mounting circular groove 307 is provided at the center position between each group of rectangular grooves 302 on the top of the conveyor turntable 3. The bottom of the mounting circular groove 307 is connected to a mounting groove 308. A mounting groove 310 is connected to one side of the mounting groove 308. A movable slide rod 311 is slidably installed inside the mounting groove 310. One end of the two movable slide rods 311 extends through the mounting groove 310 to the outside of the conveyor turntable 3 and is fixedly installed with a semi-circular pressure block 321. The semi-circular pressure block 321 is closely attached to the inner side of the arc-shaped pressure block 5. A limit plate 312 is fixedly installed at one end of the movable slide rod 311 inside the mounting groove 310. A return spring 313 is sleeved on the surface of the movable slide rod 311 inside the mounting groove 310. During operation, as the conveyor turntable 3 rotates, it causes the semi-circular pressure block 321 to approach the arc-shaped pressure block 5. The arc-shaped pressure block 5 presses against the semi-circular pressure block 321, pushing the movable slide rod 311 into the second mounting groove 310. The movable slide rod 311 pushes the trapezoidal slider 314 to slide inside the first mounting groove 308. At the same time, the limiting plate 312 compresses the reset spring 313, causing it to deform inside the second mounting groove 310. When the conveyor turntable 3 causes the semi-circular pressure block 321 to disengage from the arc-shaped pressure block 5, the reset spring 313 rebounds, lifting the limiting plate 312 and causing the movable slide rod 311 to reset, pulling the trapezoidal slider 314 to move and reset inside the first mounting groove 308.

[0024] As a further embodiment of the present invention, a fixing plate 309 is fixedly installed at the middle height position inside the mounting groove 308. A trapezoidal slider 314 is slidably installed inside the mounting groove 308, and the trapezoidal slider 314 slides close to the top of the fixing plate 309. A limiting groove 315 is symmetrically provided on one side of the trapezoidal slider 314. Mounting slide posts 316 are symmetrically slidably installed through the fixing plate 309, and the limiting groove 315 slides on the surface of the mounting slide posts 316. The bottom ends of the two mounting slide posts 316 pass through the fixing plate. A reset pressure plate 317 is fixedly connected to the bottom of the mounting groove 308 extending from 309; a downward pressure spring 318 is sleeved on the surface of the mounting slide column 316 located between the fixed plate 309 and the reset pressure plate 317; the top ends of the two mounting slide columns 316 pass through the fixed plate 309 and the trapezoidal slider 314 and are fixedly connected to a trapezoidal pressure block 319, and the trapezoidal pressure block 319 is in contact with the trapezoidal slider 314; a top plate 320 is fixedly connected to the top of the trapezoidal pressure block 319, and the top plate 320 is snapped into the inside of the mounting groove 307; During operation, as the trapezoidal slider 314 slides inside the mounting groove 308, it lifts the trapezoidal pressure block 319, pushing the top plate 320 out of the mounting circular groove 307 and the cover plate body 4 out between the four clamping rollers 306, facilitating the removal and replacement of the cover plate body 4. Simultaneously, as the trapezoidal pressure block 319 moves upward, the mounting slide column 316 pulls the reset pressure plate 317 upward, causing the downward pressure spring 318 to be squeezed and deformed between the fixed plate 309 and the reset pressure plate 317. When the trapezoidal slider 314 resets under the pull of the moving slide rod 311, the downward pressure spring 318 rebounds and presses down on the reset pressure plate 317, ensuring that the trapezoidal pressure block 319 remains firmly against the top of the trapezoidal slider 314. This causes the top plate 320 to be inserted into the mounting circular groove 307, bringing the top plate 320 and the conveyor turntable 3 into a relatively flush state, facilitating the re-clamping and fixing of the cover plate body 4 against the conveyor turntable 3 and onto the top of the top plate 320.

[0025] As a further embodiment of the present invention, the grinding mechanism 7 includes a mounting frame 701. Grinding rollers 702 are rotatably mounted on both ends of the mounting frame 701 via bearings. Grinding belts 703 are sleeved on the surfaces of the two grinding rollers 702, and the bottom of the grinding belts 703 is in close contact with the cover plate body 4. One end of one of the grinding rollers 702 passes through the mounting frame 701 and is fixedly connected to a transmission gear 704. A grinding motor 705 is fixedly mounted on one side of the top of the mounting frame 701. The output end of the grinding motor 705 is fixedly connected to a drive gear 706, and the drive gear 706 meshes with the transmission gear 704. During operation, the grinding motor 705 is started and, through the meshing of the drive gear 706 and the transmission gear 704, controls the grinding roller 702 to rotate inside the mounting frame 701, so that the grinding belt 703 rotates synchronously with the rotation of the grinding roller 702. When the grinding belt 703 is pressed against the top of the cover plate body 4, the sliding grinding belt 703 grinds the top of the cover plate body 4.

[0026] As a further embodiment of the present invention, the clamping mechanism 8 includes a concave frame 801, three clamping rods 802 are slidably connected through the top of the concave frame 801, a fixed frame 803 is fixedly connected to the bottom of the three clamping rods 802, a connecting strip 804 is fixedly connected through the top of the three clamping rods 802, a clamping spring 805 is sleeved on the surface of the clamping rods 802 between the fixed frame 803 and the top of the concave frame 801, a clamping roller 806 is rotatably mounted on the bottom of the fixed frame 803 via a rotating shaft, and the clamping roller 806 is in close contact with the top of the grinding belt 703. The concave frame 801 is symmetrically provided with limiting grooves 807 on both sides, and the fixed frame 803 is slidably connected through the limiting grooves 807 on both sides. During operation, the cover plate body 4 is pressed against the bottom of the grinding belt 703. When the grinding belt 703 is deformed by compression, the top of the grinding belt 703 gradually straightens and lifts the pressure roller 806, causing the fixing frame 803 to move upward and compress the pressure spring 805. Under the rebound action of the pressure spring 805, the pressure roller 806 is pressed tightly against the top of the grinding belt 703, ensuring that the grinding belt 703 is always in a straight and taut state. This avoids large gaps when the grinding belt 703 slides and grinds on the top of the cover plate body 4, which would affect the grinding effect of the grinding belt 703 on the top of the cover plate body 4.

[0027] A method of using an adaptively adjustable grinding machine for automotive cover plates, the method comprising the following steps: The rotating motor 2 is started, driving the rotating disk 201 to rotate, causing the pins 203 to intermittently engage with the intermittent slots 205 on the surface of the intermittent turntable 204. The intermittent turntable 204 drives the conveyor turntable 3 to rotate intermittently on the top of the base 1. During the rotation of the conveyor turntable 3, the cover plate body 4 is engaged between the corresponding top plate 320 and the four corresponding clamping rollers 306. The clamping rollers 306 are pushed to drive the sliding slider 304 to slide and compress the clamping spring 305 on the surface of the corresponding mounting slide rod 303, deforming it. Under the rebound action of the clamping spring 305, the cover plate body 4 is clamped and fixed between the four clamping rollers 306. The conveyor turntable 3 is controlled to rotate, moving the cover plate body 4 to the bottom of the grinding mechanism 7. The grinding motor 705 is started, and the transmission is activated via the drive gear 706 and the drive mechanism 705. The meshing of gear 704 controls the rotation of grinding roller 702, causing grinding belt 703 to move on the top of cover plate body 4. At the same time, it controls the extension and retraction of electric lifting seat 6 to drive grinding mechanism 7 to move down, so that grinding belt 703 is pressed against the top of cover plate body 4 for grinding. When grinding belt 703 is pressed against the top of cover plate body 4, grinding belt 703 deforms, so that the top of grinding belt 703 straightens and pushes up pressure roller 806, pushing fixed frame 803 to move up at the bottom of concave frame 801 and compressing pressure spring 805 to deform. Under the rebound of pressure spring 805, fixed frame 803 is pressed down, so that pressure roller 806 is pressed against the top of grinding belt 703, ensuring that grinding belt 703 is taut on the top of cover plate body 4 for grinding. After the cover plate body 4 is polished, the control conveyor turntable 3 rotates to move the cover plate body 4 away from the bottom of the polishing mechanism 7. During the rotation of the conveyor turntable 3, the semi-circular pressure block 321 moves closer to the arc-shaped pressure block 5, so that the semi-circular pressure block 321 is pressed against the inner wall of the arc-shaped pressure block 5. The arc-shaped pressure block 5 pushes and squeezes the semi-circular pressure block 321, causing the moving slide rod 311 to retract into the second mounting groove 310. This causes the limiting plate 312 to compress the return spring 313 inside the second mounting groove 310, deforming it. At the same time, the moving slide rod 311 drives the trapezoidal slider 314 to slide inside the first mounting groove 308. The trapezoidal slider 314 is pressed against the inclined surface on the opposite side of the trapezoidal pressure block 319, lifting the trapezoidal pressure block 319 upward. Under the drive of the mounting slide column 316, the return pressure plate 317 moves upward and approaches the fixed plate 309, compressing the downward pressure spring 318 between the fixed plate 309 and the return pressure plate 317. The top plate 320 pushes out of the mounting groove 307, pushing the cover plate body 4 between the four clamping rollers 306, making it easy to pick up and replace the polished cover plate body 4. The control turntable 3 continues to rotate, so that the semi-circular pressure block 321 moves away from the arc-shaped pressure block 5. Under the rebound action of the return spring 313, the limit plate 312 is lifted and slides back in the mounting groove 310, so that the moving slide rod 311 pulls the trapezoidal slider 314 to slide at the bottom of the trapezoidal pressure block 319. Under the rebound action of the downward pressure spring 318, the downward pressure reset plate 317 pulls the mounting slide column 316 to slide down in the limit slide groove 315 until the top plate 320 moves down and is inserted into the mounting groove 307, making it easy to put the unprocessed cover plate body 4 into the mounting groove 307 and then into the corresponding clamping rollers 306, improving the efficiency of polishing a batch of cover plate bodies 4.

9. A method of using an adaptively adjustable grinding device for automobile cover plates, as described in any one of claims 1-8, characterized in that, The method of use includes the following steps: The rotating motor (2) is started to drive the rotating disc (201) to rotate, so that the pin (203) is intermittently inserted into the intermittent slot (205) on the surface of the intermittent turntable (204). The intermittent turntable (204) is controlled to drive the conveyor turntable (3) to rotate intermittently on the top of the base (1). During the rotation of the conveyor turntable (3), the cover plate body (4) is inserted between the corresponding top plate (320) and the four corresponding clamping rollers (306). The clamping rollers (306) are pushed to drive the moving slider (304) to slide and compress the clamping spring (305) on the surface of the corresponding mounting slide rod (303) to deform. Under the rebound action of the clamping spring (305), the cover plate body (4) is clamped and fixed between the four clamping rollers (306). The conveyor turntable (3) is controlled to rotate to move the cover plate body (4) to the bottom of the grinding mechanism (7). The grinding motor (705) is started and drives the transmission through the drive gear (706) and the transmission. The meshing of gears (704) controls the rotation of the grinding roller (702), causing the grinding belt (703) to move on the top of the cover plate body (4). At the same time, the electric lifting seat (6) is controlled to extend and retract, driving the grinding mechanism (7) to move downward, so that the grinding belt (703) is pressed against the top of the cover plate body (4) to perform grinding processing on the top of the cover plate body (4). When the grinding belt (703) is pressed against the top of the cover plate body (4), the grinding belt (703) deforms. The top of the grinding belt (703) is stretched and the pressure roller (806) is lifted. The fixed frame (803) is pushed to move upward at the bottom of the concave frame (801) to compress the pressure spring (805) and deform it. Under the rebound action of the pressure spring (805), the fixed frame (803) is pressed down, so that the pressure roller (806) is pressed on the top of the grinding belt (703) to ensure that the grinding belt (703) is stretched on the top of the cover plate body (4) to grind the top of the cover plate body (4). After the cover plate body (4) is polished, the control turntable (3) rotates to move the cover plate body (4) away from the bottom of the polishing mechanism (7). During the rotation of the turntable (3), the semi-circular pressure block (321) moves closer to the arc-shaped pressure block (5), so that the semi-circular pressure block (321) is pressed against the inner wall of the arc-shaped pressure block (5). The arc-shaped pressure block (5) pushes and squeezes the semi-circular pressure block (321), causing the moving slide bar (311) to retract into the second mounting groove (310), and driving the limiting plate (312) in the second mounting groove (310). 10) The internal compression return spring (313) deforms, and at the same time the moving slide rod (311) drives the trapezoidal slider (314) to slide inside the mounting groove (308). The trapezoidal slider (314) and the inclined surface on the opposite side of the trapezoidal pressure block (319) are pressed together, pushing the trapezoidal pressure block (319) upward. Under the drive of the mounting slide column (316), the return pressure plate (317) moves upward and closes to the fixed plate (309), compressing the compression spring (318) between the fixed plate (309) and the return pressure plate (317). The deformation between the four clamping rollers (306) continues until the top plate (320) pushes out of the mounting groove (307) and pushes the cover plate body (4) out between the four clamping rollers (306), making it convenient to pick up and replace the cover plate body (4) after grinding. The control of the conveyor turntable (3) continues to rotate, so that the semi-circular pressure block (321) moves away from the arc-shaped pressure block (5). Under the rebound action of the return spring (313), the limit plate (312) is lifted and slides back in the second mounting groove (310), so that the moving slide rod (311) pulls the trapezoidal The slider (314) slides at the bottom of the trapezoidal pressure block (319). Under the rebound action of the downward pressure spring (318), the downward pressure reset plate (317) pulls the mounting slide column (316) down into the limiting slide groove (315) until the top plate (320) moves down and is inserted into the mounting round groove (307). This makes it easier to press the unprocessed cover plate body (4) against the mounting round groove (307) and insert it into the corresponding clamping roller (306), thereby improving the efficiency of grinding and processing the batch of cover plate bodies (4).
