For example, patent application number 202022996954.6, entitled "A Cleanable Automobile Body Grinding Equipment," addresses the technical problem of collecting and processing the dust generated during grinding, leading to a dirty work surface. To solve this problem, this invention provides a cleanable automobile body grinding equipment, including a base with a housing fixedly connected to the top. This equipment, through structures such as an exhaust hood and a suction fan, can draw the dust generated during grinding into a filter box for processing and purification before discharging, preventing dust accumulation on the worktable and inhalation by workers. Simultaneously, through structures such as a drive wheel and gear ring, the position of the grinding machine can be adjusted, allowing for repeated grinding of different parts of the vehicle body components, improving the grinding effect.

[0003] The aforementioned technologies have the following drawbacks: due to their limited size, these grinding devices can only grind small-sized body panels and are difficult to grind large-sized body panels, resulting in low practicality.

A limit mechanism is provided at the bottom of the support frame 4. A guide mechanism is provided inside the storage slot 6.

[0018] refer to Figure 3 The limiting mechanism includes a limiting frame 11 fixedly connected to the bottom of the support frame 4 and located outside the output end of the transmission device 2. The bottom of the limiting frame 11 is provided with a mounting groove 12. A ball bearing 13 is movably connected inside the mounting groove 12. The bottom of the ball bearing 13 extends to the outside of the mounting groove 12 and is movably connected to the top of the grinding disc 3. A lubrication mechanism is provided inside the mounting groove 12.

[0019] As a technical optimization of this utility model, by setting a limiting frame 11, a mounting groove 12 and a ball bearing 13, the grinding disc 3 is limited to avoid being impacted by external forces, causing the grinding disc 3 to tilt and resulting in the breakage of the connection between the grinding disc 3 and the output end of the transmission device 2.

[0020] refer to Figure 3 The lubrication mechanism includes a fixed groove 14 formed on the inner wall of the mounting groove 12 and located on the top of the ball 13. A solid lubricant 15 is fixedly connected inside the fixed groove 14. The bottom of the solid lubricant 15 passes through the fixed groove 14 and is movably connected to the top of the ball 13.

[0021] As a technical optimization of this utility model, by setting a fixed groove 14 and a solid lubricant 15, when the solid lubricant 15 rubs against the ball 13, the lubricant in the solid lubricant 15 will be transferred to the ball 13 to lubricate the ball 13, reduce the wear of the ball 13, and extend the service life of the ball 13.

Sliding blocks 17 are fixedly connected to both sides of the rubber wheel 8, and the outer side of the sliding blocks 17 extends into the interior of the guide grooves 16.

[0023] As a technical optimization of this utility model, by setting the guide groove 16 and the sliding block 17, the rubber wheel 8 is guided and limited when it moves up and down, so as to avoid the rubber wheel 8 tilting and affecting the normal operation of the grinding device.

[0024] refer to Figure 5 An auxiliary handle 18 located on the back of the support frame 4 is fixedly connected to the top of the support frame 4, and an anti-slip rubber 19 is fixedly connected to the surface of the auxiliary handle 18.

[0025] As a technical optimization of this utility model, by setting an auxiliary handle 18, the worker is provided with a position to apply force to move the grinding device, and the anti-slip rubber 19 is used to increase the surface friction of the auxiliary handle 18, so as to prevent the grinding device from slipping out of the worker's control when moving the grinding device.

[0026] refer to Figure 4 The top of the support frame 4 is fixedly connected to a counterweight water tank 20 located on both sides of the support frame 4. The counterweight water tank 20 is located outside the gas transmission pipe 10, and a drain valve 21 is connected to the outside of the counterweight water tank 20.

[0027] As a technical optimization of this utility model, by setting a counterweight water tank 20, the weight of the grinding device is increased, the impact of vibration on the grinding device is reduced, and the drain valve 21 is used to facilitate the worker to drain the water in the counterweight water tank 20, thereby reducing the weight of the grinding device and making it easier for the worker to move the grinding device.

[0028] The working principle and usage process of this utility model are as follows: When in use, first place the grinding device on the body panel, then start the air pump 9. The air pump 9 will deliver air into the telescopic airbag 7, causing the telescopic airbag 7 to expand. The telescopic airbag 7 pushes the rubber wheel 8 downward by expanding, so that the rubber wheel 8 and the grinding disc 3 are in contact with the surface of the body panel. Then start the motor 5. The motor 5 drives the grinding disc 3 to rotate through the output end and the transmission 2. The grinding disc 3 grinds the surface of the body panel by rotating. At the same time, the worker pushes the grinding device to move by using the auxiliary handle 18 to adjust the position of the grinding device, so as to grind all parts of the surface of the body panel.

[0029] In summary, this grinding device for automobile body production uses a motor 5, a transmission device 2, and a grinding disc 3 to grind the body panels. The position of the grinding disc 3 is adjusted by an air pump 9, an air supply pipe 10, a telescopic airbag 7, and rubber wheels 8. The rubber wheels 8 facilitate the movement of the grinding device, allowing it to grind body panels of different sizes, thereby improving the practicality of the grinding device.
