The support rods slide through the limit holes, and the other end of the support rods is hinged to the outside of the adaptive adjustment component through the pins. A limit rod is provided between the two support rods, and the end of the limit rod is fixed to the inner wall of the outer baffle plate. The limit rod slides through the slide hole, and three slideways are provided on the outer wall of the outer baffle plate.

[0010] As a further solution of the present invention, the polishing assembly includes a polishing plate, which is overlapped on the outside of the outer baffle plate. Three limit bars are fixedly connected to the inner wall of the polishing plate. The limit bars are slidably connected in the slideway, and the cross-sectional shapes of the limit bars and the slideway are both T-shaped.

[0011] As a further solution of the present invention, the dust suction assembly includes two dust suction hoods, the dust suction hoods are installed on the top of the protective cover, the back of the dust suction hoods are connected to an air duct, the ends of the two air ducts are connected to dust filter boxes, the bottom of the dust filter box is connected to a main pipe, the bottom end of the main pipe is installed with a fan, and the fan is installed on the back of the machine base.

[0012] As a further solution of the present invention, anti-slip pads are respectively provided at the four corners of the bottom of the support base, and observation brackets are respectively provided on both sides of the machine base. The observation brackets are installed on one side of the protective cover, and a transparent observation window is provided in the observation bracket.

[0013] A method for using a polishing device for automobile cover plate processing, the method comprising the following steps:

[0014] The automobile cover to be polished is mounted on an external workbench, and the external workbench is pushed to one side of the machine base, so that the automobile cover to be polished is located below the supporting wheel. The driving motor is controlled to work so that its output shaft drives the supporting wheel to rotate, and the supporting wheel drives four adaptive adjustment components to rotate, and the adaptive adjustment component drives the external polishing component to rotate. The automobile cover is pushed to make it contact with the polishing component, so that the polishing component can achieve the purpose of polishing the surface of the automobile cover;

[0015] When the convex surface on the automobile cover contacts the polishing assembly, the convex surface will squeeze the polishing assembly, and the polishing assembly will squeeze the outer baffle, so that the multiple outer baffles can be gathered toward the middle of the support wheel. After being compressed, the outer baffle will squeeze the two support rods, so that the support rods can deflect and squeeze the two sliding sleeves, so that the two sliding sleeves can approach each other outside the sliding rod. With the elastic force of the two support springs, a reverse supporting force can be given to the sliding sleeve, so that the sliding sleeve can support the outer baffle through the support rod, so that the polishing assembly can move while keeping close contact with the outer wall of the automobile cover, ensuring the polishing effect;

[0016] When the concave surface on the automobile cover plate contacts the polishing assembly, the sliding sleeve is supported by the elastic force of the two supporting springs, so that the sliding sleeve squeezes the outer baffle plate through the two supporting rods, so that the four outer baffle plates drive the four polishing assemblies to unfold and contact the surface of the automobile cover plate, and the concave surface position of the automobile cover plate can be polished. Therefore, the polishing device can adaptively adjust the position of the polishing assembly according to the curved surface of the automobile cover plate. During the sliding of the sliding sleeve on the outer wall of the sliding rod, the sliding sleeve is buffered and damped by the damping spring arranged on the outer surface of the sliding rod, so as to prevent the jitter generated by the polishing assembly during operation from being transmitted to the sliding sleeve, thereby causing the adaptive adjustment assembly to continue shaking, and the stability of the polishing work is ensured by reducing the floating frequency of the adaptive adjustment assembly.

[0017] When the polishing assembly is polishing the automobile cover, some dust gas will be generated. The fan is controlled to work so that the dust hood can extract the dust gas below. The dust gas enters the dust filter box through the air duct. The dust filter box can filter the gas containing dust, and the dust is isolated in the dust filter box. The gas passes through the main pipe and is discharged from the air outlet of the fan to prevent the dust gas from spreading and affecting the working environment. In addition, during the polishing process, the polishing status can be observed through the transparent observation window in the observation bracket to prevent residual material from splashing and causing safety hazards. When replacing the polishing assembly, the polishing plate is pulled outward from the outside of the adaptive adjustment assembly so that the polishing plate drives the limit strip to slide out of the slideway in the adaptive adjustment assembly so that the polishing plate can be removed. When installing the polishing plate, the T-shaped limit strip at the bottom of the polishing plate is embedded in the T-shaped slideway to limit the polishing plate so that the polishing plate will not separate from the adaptive adjustment assembly during rotation.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention polishes the automobile cover plate by pushing the automobile cover plate to make it contact with the polishing assembly. When the convex surface on the automobile cover plate contacts the polishing assembly, the convex surface will squeeze the polishing assembly, and the polishing assembly will squeeze the outer baffle plate, so that the multiple outer baffle plates can be gathered toward the middle of the supporting wheel. After the outer baffle plate is pressed, it will squeeze the two support rods and the sliding sleeve. The two sliding sleeves can approach each other outside the sliding rod, and with the elastic force of the two support springs, a reverse supporting force can be given to the sliding sleeve, so that the sliding sleeve can support the outer baffle plate through the support rod, so that the polishing assembly moves while maintaining contact with the automobile. The outer wall of the car cover fits tightly to ensure the polishing effect. When the concave surface on the car cover contacts the polishing component, the sliding sleeve is supported by the elastic force of the two supporting springs, so that the sliding sleeve squeezes the outer baffle plate through the two supporting rods, so that the four outer baffle plates drive the four polishing components to unfold and contact the surface of the car cover, and the concave surface of the car cover can be polished. Therefore, the polishing device can adaptively adjust the position of the polishing component according to the curved surface of the car cover, and the car cover can be directly pushed into the polishing device horizontally, which reduces the workload and improves the polishing efficiency.

[0020] 2. The present invention performs buffering and damping on the sliding sleeve through the damping spring arranged on the outer surface of the sliding rod, so as to prevent the jitter generated during the operation of the polishing component from being transmitted to the sliding sleeve, thereby causing the adaptive adjustment component to continue to shake, and ensure the stability of the polishing work by reducing the floating frequency of the adaptive adjustment component. In addition, some dust gas will be generated during the polishing process, and the fan is controlled to operate so that the dust hood can extract the dust gas below, and the dust gas enters the dust filter box through the air duct. The dust filter box can filter the gas containing dust, and the dust is isolated in the dust filter box. The gas passes through the main pipe and is discharged from the air outlet of the fan, so as to prevent the dust gas from spreading and affecting the working environment. In addition, during the polishing process, the polishing state can be observed through the transparent observation window in the observation bracket to prevent residual material from splashing and causing safety hazards.

[0049] The automobile cover to be polished is mounted on the external workbench, and the external workbench is pushed to one side of the machine base 1, so that the automobile cover to be polished is located below the supporting wheel 4, and the driving motor 3 is controlled to work so that its output shaft drives the supporting wheel 4 to rotate, and the supporting wheel 4 drives the four adaptive adjustment components 7 to rotate, and the adaptive adjustment component 7 drives the external polishing component 8 to rotate, and the automobile cover is pushed to make it contact with the polishing component 8, so that the polishing component 8 can achieve the purpose of polishing the surface of the automobile cover;

[0050] When the convex surface on the automobile cover plate contacts the polishing assembly 8, the convex surface will squeeze the polishing assembly 8, and the polishing assembly 8 will squeeze the outer baffle 701, so that the multiple outer baffles 701 can be gathered toward the middle of the support wheel 4. After being compressed, the outer baffle 701 will squeeze the two support rods 702, so that the support rods 702 can deflect and squeeze the two sliding sleeves 603, so that the two sliding sleeves 603 can be close to each other outside the sliding rod 601, and with the elastic force of the two support springs 604, a reverse supporting force can be given to the sliding sleeve 603, so that the sliding sleeve 603 can support the outer baffle 701 through the support rod 702, so that the polishing assembly 8 can move while maintaining a close fit with the outer wall of the automobile cover plate, thereby ensuring the polishing effect;

[0051] When the concave surface on the automobile cover plate contacts the polishing assembly 8, the elastic force of the two supporting springs 604 is used to support the sliding sleeve 603, so that the sliding sleeve 603 squeezes the outer baffle plate 701 through the two supporting rods 702, so that the four outer baffle plates 701 drive the four polishing assemblies 8 to unfold and contact the surface of the automobile cover plate, and the concave surface position of the automobile cover plate can be polished.

The fan (115) is controlled to work so that the dust hood (111) can extract the dust gas below. The dust gas enters the dust filter box (113) through the air duct (112). The dust filter box (113) can filter the gas containing dust, and the dust is isolated in the dust filter box (113). The gas passes through the main pipe (114) and is discharged from the air outlet of the fan (115), thereby preventing the dust gas from spreading and affecting the working environment. In addition, during the polishing process, the polishing process can be observed through the transparent observation window in the observation bracket (12). The polishing plate (801) is pulled outward from the outside of the adaptive adjustment component (7) to enable the polishing plate (801) to drive the limiting strip (802) to slide out of the slideway (704) in the adaptive adjustment component (7) so that the polishing plate (801) can be removed. When installing the polishing plate (801), the T-shaped limiting strip (802) at the bottom of the polishing plate (801) is embedded in the T-shaped slideway (704) to limit the polishing plate (801) so that the polishing plate (801) will not separate from the adaptive adjustment component (7) during rotation.
