[0013] A method of using a polishing apparatus for processing automotive cover plates, the method comprising the following steps: During the processing of the car cover, the car cover is placed on the conveyor belt on the left. The conveyor belt transports the car cover to the right. The first motor is started, causing the lead screw to rotate. During the rotation of the lead screw, the nut drives two transfer components to move to the left through the cross plate. This causes the sliding hole in the cross plate to push the column to slide in the slide rail through the slider. When the column slides to the inclined surface on the left side of the Z-shaped slide rail, the column changes its trajectory and moves along the inclined surface inside the slide rail. At the same time, the column drives the slider to slide outside the slide bar, causing the sliders on the front and rear sides to move away from each other. That is, the uprights on the two columns move away from each other, increasing the two The distance between the rubber pads is adjusted to allow the two rubber pads to be moved to the front and rear sides of the car cover. When the car cover is clamped and pushed, the first motor is controlled to rotate in the opposite direction, causing the lead screw to reverse. The nut then drives the two transfer components to move to the right through the cross plate. When the column slides to the right on the inclined surface in the slide rail, it drives the bottom slider to slide outside the slide rod. At this time, the two sliders move closer to each other. When the column slides into the horizontal position in the slide rail, the two rubber pads contact the front and rear sides of the car cover and clamp it. At the same time, the cross plate drives the car cover to move to the right through the two transfer components, so that the car cover slides on the roller. The polishing head is installed in a slot within the tray and locked in place by bolts passing through the polishing head and positioning holes. Next, two electro-hydraulic rods and a second motor are controlled. The second motor drives the driven gear to rotate via a drive gear. Since the diameter of the drive gear is much larger than that of the driven gear, the rotational speed of the support cylinder driven by the driven gear is increased. Furthermore, the counterweight on the side of the protective shell away from the second motor balances the weight on both sides of the protective shell, improving the stability of the support cylinder driving the adaptive polishing assembly's rotation. During the rotation of the adaptive polishing assembly, the three trays, under centrifugal force, cause the three polishing heads to unfold outwards. Simultaneously, the trays pull the fixed seats to slide outside the central column and limit rod via two support rods. The support rods also drive the deflection rod in the middle to deflect. During this process, the two fixed seats move away from each other. The limit rod and central column support and guide the fixed seats, improving the stability of the horizontal movement of the fixed seats and achieving the purpose of synchronous adjustment of the three trays. Secondly, the two electro-hydraulic rods extend and move the protective shell downwards. The protective shell, in turn, moves the support cylinder downwards. The support cylinder moves the adaptive polishing assembly downwards and into contact with the surface of the car cover, allowing the rotating polishing head to polish the surface of the car cover. The extraction pipe is connected to an external dust collection device to prevent dust from scattering during polishing. During this process, the two transfer components move the car cover horizontally to the right, supported by rollers at the bottom to reduce friction during horizontal movement. Polishing the moving car cover improves polishing efficiency. If there is a... When the curvature and surface are fixed, the protrusion will squeeze the polishing head in the support plate. After the support plate is pressed, it will squeeze the ends of the two support rods. The end of the support rod inside the support cylinder will push the fixed seat to slide outside the central column, so that the two fixed seats are close to each other. With the pull of the spring, the fixed seat is given a force that moves towards the stop block, so that the support rod on the fixed seat can transmit the force to the polishing head on the support plate, so that the polishing head is in close contact with the protrusion of the car cover. When polishing the concave part of the cover, during the rotation of the support cylinder, the support plate will be driven by centrifugal force to open outward and fit into the concave part for polishing. When the polishing work on the surface of the car cover is completed, the two transfer components continue to move the car cover to the right. When the column in the transfer component slides to the inclined surface on the right side of the slide, the column will move along the inclined surface inside the slide. At the same time, the column drives the slider to slide outside the slide rod, so that the sliders on the front and rear sides move away from each other. The two columns drive the two rubber pads to move away from each other through the upright plate until the rubber pads are completely separated from the front and rear sides of the car cover. At this time, the bottom of the car cover slides into the right conveyor belt conveyor mechanism. The conveyor belt conveyor mechanism works to send the car cover out of the processing table. Then, the position of the transfer component is adjusted to the left conveyor belt conveyor mechanism to facilitate the re-clamping and transfer of the car cover.
[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, during the rotation of the adaptive polishing assembly driven by the support cylinder, the three pallets, under the action of centrifugal force, cause the three polishing heads to unfold outward. Then, the positions of the protective shell, support cylinder, and adaptive polishing assembly are adjusted so that the adaptive polishing assembly contacts the surface of the car cover. During this process, two transfer components move the car cover horizontally to the right. Polishing the car cover while it is in motion improves polishing efficiency. If the car cover surface has a certain curvature or concavity, the protruding parts will squeeze the polishing heads in the pallets. After being pressed, the pallets will squeeze the ends of the two support rods located inside the support cylinder. The end will push the fixed seat to slide outside the central column, bringing the two fixed seats closer together. With the pull of the spring, a force is applied to the fixed seat towards the stop block, allowing the support rod on the fixed seat to transmit the force to the polishing head on the support plate. This makes the polishing head fit tightly against the raised part of the car cover. When polishing the concave part of the cover, as the support cylinder rotates, the support plate is subjected to centrifugal force, which will cause the polishing head to unfold outward and fit against the concave part for polishing. This allows the polishing head to fully fit against the cover surface, improving polishing uniformity and efficiency. No further finishing is required, meeting the needs of modern production line mass production.
[0015] 2. This invention starts the first motor to drive the lead screw to rotate. During the rotation of the lead screw, the nut drives the two transfer components to move to the left through the horizontal plate. This causes the sliding hole in the horizontal plate to push the column to slide in the slide rail through the slider. When the column slides to the inclined surface on the left side of the Z-shaped slide rail, the column changes its trajectory and moves along the inclined surface in the slide rail. That is, the uprights on the two columns move away from each other, increasing the distance between the two rubber pads, so as to move the two rubber pads to the front and rear sides of the car cover. When clamping and pushing the car cover, the first motor is controlled to drive the lead screw to reverse, and the nut drives the two transfer components to move to the right through the horizontal plate. When the column slides to the right on the inclined surface in the slide rail, the two sliders move closer to each other. When the column slides into the horizontal surface in the slide rail... When positioned, the two rubber pads contact and clamp the front and rear sides of the car cover. Simultaneously, the horizontal plate moves the car cover to the right via two transfer components, cooperating with the adaptive polishing component to polish the car cover, improving polishing efficiency. After polishing the surface of the car cover, the two transfer components continue to move the car cover to the right. When the column in the transfer component slides to the inclined surface on the right side of the slide, the column will move along the inclined surface in the slide. Similarly, the two columns move the two rubber pads away from each other and completely detach from the car cover via the vertical plate. At this time, the bottom of the car cover slides into the right-side conveyor belt conveyor mechanism, realizing the purpose of automated clamping, transfer, and conveying of the car cover, improving the degree of automation and processing efficiency.

Two electro-hydraulic rods 11 are fixed at the top inside the support frame 2. A protective shell 13 is fixed at the bottom of the two electro-hydraulic rods 11. A support cylinder 15 is rotatably connected to both sides of the inside of the protective shell 13 through bearings. Grooves 16 are opened on both sides of the support cylinder 15. A transmission component 17 and a counterweight 18 are fixed in the two grooves 16 respectively. The bottom of the transmission component 17 is fixedly connected to one end of the support cylinder 15. An adaptive polishing component 20 is fixed inside the support cylinder 15. The adaptive polishing component 20 passes through the support cylinder 15 and extends to the outside.
[0021] As a further embodiment of the present invention, conveyor belt conveying mechanisms 3 are respectively installed on both sides of the processing table 1, and a plurality of rollers 4 are provided between the two conveyor belt conveying mechanisms 3. The rollers 4 are rotatably connected to the middle of the processing table 1, and the top of the conveyor belt conveying mechanism 3 is flush with the top of the rollers 4. During operation, the transfer component 10 drives the car cover to move to the right, causing the car cover to slide on the roller 4. The bottom roller 4 supports the car cover, reducing the friction of the car cover's horizontal movement.
[0022] As a further embodiment of the present invention, two reinforcing rods 12 are fixed between the protective shell 13 and the end of the electric hydraulic rod 11, and two air extraction pipes 14 are fixed through the middle of the protective shell 13. During operation, the reinforcement rod 12 increases the strength of the connection between the protective shell 13 and the bottom of the electric hydraulic rod 11, and improves the stability of the protective shell 13 driving the adaptive polishing assembly 20 to move up and down; the air extraction pipe 14 is connected to an external dust collection device to prevent the dust generated during polishing from scattering.
[0023] As a further embodiment of the present invention, the drive assembly 8 includes a first motor 801, which is fixed on one side of the processing table 1. A lead screw 802 is fixed on the output shaft of the first motor 801, and the other end of the lead screw 802 is rotatably connected to the other side of the processing table 1. A nut 803 is externally threaded onto the lead screw 802, and a horizontal plate 804 is fixed to the outside of the nut 803. The horizontal plate 804 slides in two slide grooves 7. The transfer assembly 10 includes a slider 101. Sliding holes 9 are respectively opened at the front and rear ends of the horizontal plate 804. The slider 101 is slidably connected in the sliding holes 9. A sliding rod 102 slides through the middle of the slider 101. The sliding rod 102 is fixed inside the sliding hole 9. A column 103 is fixed on the slider 101. The column 103 slides through the slide rail 6. A vertical plate 104 is fixed on the column 103. A rubber pad 105 is provided on the side of the vertical plate 104 near the processing table 1. During operation, as the lead screw 802 rotates in the forward direction, the nut 803 drives the two transfer components 10 to move to the left through the horizontal plate 804. This causes the sliding hole 9 in the horizontal plate 804 to push the column 103 to slide in the slide rail 6 through the slider 101. When the column 103 slides to the inclined surface on the left side of the Z-shaped slide rail 6, the column 103 will change its trajectory and move along the inclined surface inside the slide rail 6. At the same time, the column 103 drives the slider 101 to slide outside the slide rod 102, causing the sliders 101 on the front and rear sides to move away from each other. That is, the vertical plates 104 on the two columns 103 move away from each other, increasing the distance between the two rubber pads 105, so as to facilitate the movement of the two rubber pads 105 to the front and rear sides of the car cover. During the reverse rotation of the lead screw 802, the two transfer components 10 are moved to the right by the horizontal plate 804. When the column 103 slides to the right on the inclined surface in the slide rail 6, it drives the bottom slider 101 to slide outside the slide rod 102. At this time, the two sliders 101 move closer to each other. When the column 103 slides into the horizontal position in the slide rail 6, the two rubber pads 105 contact the front and rear sides of the car cover and clamp it. At the same time, the horizontal plate 804 drives the car cover to move to the right through the two transfer components 10, so as to achieve the purpose of automatically clamping and moving the cover.
[0024] As a further embodiment of the present invention, the transmission assembly 17 includes a second motor 171, which is fixed inside the groove 16. A drive gear 172 is fixed on the output shaft of the second motor 171. A driven gear 173 is meshed with the bottom of the drive gear 172. The diameter of the drive gear 172 is much larger than that of the driven gear 173. The driven gear 173 is fixedly connected to the end of the support cylinder 15. During operation, since the diameter of the driving gear 172 is much larger than that of the driven gear 173, the rotational speed of the driven gear 173 driving the support cylinder 15 is increased, ensuring the polishing effect of the adaptive polishing component 20; the counterweight 18 on the side of the protective shell 13 away from the second motor 171 will balance the weight on both sides of the protective shell 13, improving the stability of the support cylinder 15 driving the adaptive polishing component 20 to rotate.
[0025] As a further embodiment of the present invention, the adaptive polishing assembly 20 includes a central column 201, which is fixed to both sides of the inner wall of the support cylinder 15. Fixing seats 203 are slidably inserted through both sides of the middle part of the central column 201. A stop block 204 is provided on the side of the two fixing seats 203 that are far apart from each other. The stop block 204 is fixedly connected to the outside of the central column 201. Three limiting rods 202 are fixedly inserted through the two stop blocks 204. The limiting rods 202 are fixed to both sides inside the support cylinder 15, and the three limiting rods 202 slide through the fixing seats 203. A spring 205 is fixed between the corresponding stop block 204 and the fixing seat 203. The spring 205 is sleeved on the outside of the central column 201. During operation, when polishing the raised parts of the car cover surface, the raised parts will press against the polishing head in the support plate 208. After being pressed, the support plate 208 will press against the ends of the two support rods 206. The end of the support rod 206 located inside the support cylinder 15 will push the fixed seat 203 to slide outside the central column 201, so that the two fixed seats 203 are close to each other. With the pulling force of the spring 205, the fixed seat 203 is given a force that moves towards the stop block 204, so that the support rod 206 on the fixed seat 203 can transmit the force to the polishing head on the support plate 208, so that the polishing head is in close contact with the raised parts of the car cover, ensuring the polishing effect.
[0026] As a further embodiment of the present invention, the three ends of the fixed base 203 are respectively rotatably connected to the support rod 206 by a pin, the middle part of the support rod 206 is rotatably connected to the deflection rod 207 by a pin, the other end of the deflection rod 207 is rotatably connected to the end of the stop block 204 by a pin, and the support cylinder 15 is provided with limit holes 19 at the positions corresponding to the support rod 206, and the support rod 206 slides through the limit holes 19. The ends of the two corresponding support rods 206 away from the fixed base 203 are rotatably connected to the support plate 208 by a pin, and the support plate 208 is provided with a slot 209, and the four corners of the slot 209 are respectively provided with positioning holes 2010. During operation, the support rod 206 is limited by the limiting hole 19 to improve the deflection stability of the support rod 206. When the position of the support rod 206 relative to the support plate 208 is adjusted, the deflection rod 207 provides auxiliary support to the middle part of the support rod 206, improving the stability of the support plate 208 and the polishing head. The polishing head is installed in the slot 209 in the support plate 208 and locked by a bolt through the polishing head and the positioning hole 2010. When removing the polishing head, the bolt is unscrewed to pull out the polishing head, which facilitates the independent replacement of multiple polishing heads.
[0027] A method of using a polishing apparatus for processing automotive cover plates, the method comprising the following steps: When processing the car cover, the car cover is placed on the left-side conveyor belt 3. The conveyor belt 3 transports the car cover to the right. The first motor 801 is started, causing the lead screw 802 to rotate. During the rotation of the lead screw 802, the nut 803 drives the two transfer components 10 to move to the left through the horizontal plate 804. This causes the sliding hole 9 in the horizontal plate 804 to push the column 103 to slide in the slide rail 6 through the slider 101. When the column 103 slides to the inclined surface on the left side of the Z-shaped slide rail 6, the column 103 changes its trajectory and moves along the inclined surface inside the slide rail 6. At the same time, the column 103 drives the slider 101 to slide outside the slide rod 102, causing the sliders 101 on the front and rear sides to move away from each other, that is, the upright plates 104 on the two columns 103 move away from each other. To increase the distance between the two rubber pads 105, so as to move the two rubber pads 105 to the front and rear sides of the car cover, when the car cover is clamped and pushed, the first motor 801 is controlled to rotate in the opposite direction, so that the lead screw 802 is reversed. The nut 803 then drives the two transfer components 10 to move to the right through the horizontal plate 804. When the column 103 slides to the right on the inclined surface in the slide rail 6, it drives the bottom slider 101 to slide outside the slide rod 102. At this time, the two sliders 101 approach each other. When the column 103 slides into the horizontal position in the slide rail 6, the two rubber pads 105 contact the front and rear sides of the car cover and clamp it. At the same time, the horizontal plate 804 drives the car cover to move to the right through the two transfer components 10, so that the car cover slides on the roller 4. The polishing head is installed in the slot 209 within the support plate 208 and locked by bolts passing through the polishing head and the positioning hole 2010. Next, the two electro-hydraulic rods 11 and the second motor 171 are controlled to operate. The second motor 171 drives the driven gear 173 to rotate via the drive gear 172. Since the diameter of the drive gear 172 is much larger than the diameter of the driven gear 173, the rotational speed of the support cylinder 15 driven by the driven gear 173 is increased. Furthermore, the counterweight 18 on the side of the protective shell 13 away from the second motor 171 balances the weight on both sides of the protective shell 13, increasing the rotational speed of the adaptive polishing assembly 20 driven by the support cylinder 15. To improve rotational stability, during the rotation of the adaptive polishing assembly 20 driven by the support cylinder 15, the three support plates 208 are subjected to centrifugal force, causing the three polishing heads to unfold outward. At the same time, the support plates 208 pull the fixed seats 203 to slide outside the central column 201 and the limiting rod 202 through the two support rods 206. Meanwhile, the support rods 206 drive the deflection rod 207 in the middle to deflect. During this process, the two fixed seats 203 move away from each other. The fixed seats 203 are supported and guided by the limiting rod 202 and the central column 201, which improves the stability of the horizontal movement of the fixed seats 203 and achieves the purpose of synchronous adjustment of the three support plates 208. Secondly, the two electric hydraulic rods 11 extend and drive the protective shell 13 downward, which in turn drives the support cylinder 15 downward. The support cylinder 15 drives the adaptive polishing component 20 downward and into contact with the surface of the car cover, so that the polishing head in the rotating state polishes the surface of the car cover. The exhaust pipe 14 is connected to the external dust collection equipment to prevent the dust generated during polishing from scattering. During this process, the two transfer components 10 will drive the car cover to move horizontally to the right. The bottom roller 4 supports the car cover, reducing the friction of the horizontal movement of the car cover. By polishing the car cover in the moving state, the polishing efficiency is improved. If the surface of the car cover has a certain curvature and concavity, the protruding parts will squeeze... The polishing head in the pressure plate 208, after the pressure plate 208 is pressed, will squeeze the ends of the two support rods 206. The end of the support rod 206 located inside the support cylinder 15 will push the fixed seat 203 to slide outside the central column 201, so that the two fixed seats 203 are close to each other. With the pull of the spring 205, a force is given to the fixed seat 203 to move towards the stop block 204, so that the support rod 206 on the fixed seat 203 can transmit the force to the polishing head on the pressure plate 208, so that the polishing head is in close contact with the raised part of the car cover. When polishing the concave part of the cover, during the rotation of the support cylinder 15, the pressure plate 208 will be driven by centrifugal force to spread the polishing head outward and fit into the concave part for polishing. When the polishing work on the surface of the car cover is completed, the two transfer components 10 continue to move the car cover to the right. When the column 103 in the transfer component 10 slides to the inclined surface on the right side of the slide rail 6, the column 103 will move along the inclined surface inside the slide rail 6. At the same time, the column 103 drives the slider 101 to slide outside the slide rod 102, so that the sliders 101 on the front and rear sides move away from each other. The two columns 103 respectively drive the two rubber pads 105 to move away from each other through the upright plate 104 until the rubber pads 105 are completely separated from the front and rear sides of the car cover. At this time, the bottom of the car cover slides into the right conveyor belt conveyor mechanism 3. The conveyor belt conveyor mechanism 3 works to send the car cover out of the processing table 1. Then, the position of the transfer component 10 to the left conveyor belt conveyor mechanism 3 is adjusted so that the car cover can be clamped and transferred again.

9. A method of using a polishing apparatus for processing automobile hood panels, as described in any one of claims 1-8, characterized in that, The method of use includes the following steps: When processing the car cover, the car cover is placed on the conveyor belt conveyor (3) on the left side. The conveyor belt conveyor (3) transports the car cover to the right. The first motor (801) is started to drive the lead screw (802) to rotate. During the rotation of the lead screw (802), the nut (803) drives the two transfer components (10) to move to the left through the horizontal plate (804). The sliding hole (9) in the horizontal plate (804) pushes the column (103) to slide in the slide rail (6) through the slider (101). When the column (103) slides to the inclined surface on the left side of the Z-shaped slide rail (6), the column (103) will change its movement trajectory and move along the inclined surface in the slide rail (6). At the same time, the column (103) drives the slider (101) to slide outside the slide rod (102), so that the sliders (101) on the front and rear sides move away from each other, that is, the vertical plates (10) on the two columns (103) move away from each other. 4) Move away from each other to increase the distance between the two rubber pads (105) so that the two rubber pads (105) can be moved to the front and rear sides of the car cover. When the car cover is clamped and pushed, the first motor (801) is controlled to rotate in the opposite direction so that the lead screw (802) rotates in the opposite direction. The nut (803) drives the two transfer components (10) to move to the right through the horizontal plate (804). When the column (103) slides to the right on the inclined surface in the slide (6), it drives the bottom slider (101) to slide outside the slide rod (102). At this time, the two sliders (101) approach each other. When the column (103) slides into the horizontal position in the slide (6), the two rubber pads (105) contact the front and rear sides of the car cover and clamp it. At the same time, the horizontal plate (804) drives the car cover to move to the right through the two transfer components (10), so that the car cover slides on the roller (4). The polishing head is installed in the slot (209) in the support plate (208) and locked by bolts through the polishing head and the positioning hole (2010). Then, the two electric hydraulic rods (11) and the second motor (171) are controlled to work. The second motor (171) drives the driven gear (173) to rotate through the drive gear (172). Since the diameter of the drive gear (172) is much larger than the diameter of the driven gear (173), the rotation speed of the driven gear (173) driving the support cylinder (15) is increased. The counterweight (18) on the side of the protective shell (13) away from the second motor (171) will balance the weight on both sides of the protective shell (13), and increase the rotation speed of the support cylinder (15) driving the adaptive polishing assembly (2010). To improve the stability of rotation, during the rotation of the adaptive polishing assembly (20) driven by the support cylinder (15), the three trays (208) will be driven by centrifugal force to extend the three polishing heads outward. At the same time, the trays (208) will pull the fixed seat (203) to slide outside the central column (201) and the limiting rod (202) through the two support rods (206). Meanwhile, the support rods (206) will drive the deflection rod (207) in the middle to deflect. During this process, the two fixed seats (203) will move away from each other. The fixed seat (203) will be supported and guided by the limiting rod (202) and the central column (201), which will improve the stability of the horizontal movement of the fixed seat (203) and achieve the purpose of synchronous adjustment of the three trays (208). Next, the two electric hydraulic rods (11) extend and drive the protective shell (13) to move downwards. The protective shell (13) then drives the support cylinder (15) to move downwards. The support cylinder (15) drives the adaptive polishing assembly (20) to move downwards and contact the surface of the car cover, so that the polishing head in the rotating state polishes the surface of the car cover. The exhaust pipe (14) is connected to the external dust collection equipment to prevent the dust generated by polishing from scattering. During this process, the two transfer assemblies (10) will drive the car cover to move horizontally to the right. The bottom roller (4) supports the car cover, reducing the friction of the horizontal movement of the car cover. By polishing the car cover in the moving state, the polishing efficiency is improved. If the surface of the car cover has a certain curvature and curve, the protruding part will squeeze the support plate (208). When the polishing head in the support cylinder (15) is pressed, the support plate (208) will squeeze the ends of the two support rods (206). The end of the support rod (206) located inside the support cylinder (15) will push the fixed seat (203) to slide outside the central column (201), so that the two fixed seats (203) are close to each other. With the pull of the spring (205), the fixed seat (203) is given a force that moves towards the stop (204), so that the support rod (206) on the fixed seat (203) can transmit the force to the polishing head on the support plate (208), so that the polishing head is in close contact with the raised part of the car cover. When polishing the concave part of the cover, the support cylinder (15) rotates, and the support plate (208) is driven by centrifugal force to spread the polishing head outward and fit the concave part for polishing. When the polishing work of the car cover surface is completed, the two transfer components (10) continue to drive the car cover to move to the right. When the column (103) in the transfer component (10) slides to the inclined surface on the right side of the slide (6), the column (103) will move along the inclined surface in the slide (6). At the same time, the column (103) drives the slider (101) to slide outside the slide rod (102), so that the sliders (101) on the front and rear sides move away from each other. The two columns (103) drive the two rubber pads (105) to move away from each other through the upright plate (104) until the rubber pads (105) are completely separated from the front and rear sides of the car cover. At this time, the bottom of the car cover slides into the right conveyor belt conveyor mechanism (3). The conveyor belt conveyor mechanism (3) works to send the car cover out of the processing table (1). Then, the position of the transfer component (10) is adjusted to the left conveyor belt conveyor mechanism (3) so that the car cover can be clamped and transferred again.
