[0032] Two triangular ring frames 6 are fixed on the right side of the top surface of the operating table 1, and an electric telescopic rod 9 is fixedly installed on the inner wall of the triangular ring frame 6. A horizontal plate 10 is fixed on the left side of the telescopic end of the electric telescopic rod 9. Two sliding holes are opened on the left side of the horizontal plate 10. Two grinding rollers 11 are rotatably installed on the left side of the horizontal plate 10. The two grinding rollers 11 are respectively located in front and behind the left side of the horizontal plate 10. Two U-shaped guide rails 12 are fixed on the top surface of the operating table 1, and two oblique frames 13 are fixed on the right side of the horizontal plate 10. The bottom of the left side of the oblique frame 13 is provided with a circular hole, and a roller 14 is rotatably installed on the inner wall of the oblique frame 13. The roller 14 is located at the bottom end of the U-shaped guide rail 12. An anti-slip assembly is arranged in each slide hole, two grinding rollers 11 are respectively located on the inner wall of the wheel hub, two U-shaped guide rails 12 are respectively located in front and behind the square opening of the operating table 1, and two inclined frames 13 are arranged in an inverted eight-shaped shape, and the roller 14 rolls in the U-shaped guide rail 12. Under the support of the roller 14, the grinding roller 11 on the cross plate 10 moves stably to the left, and the U-shaped guide rail 12 limits the roller 14, so that the grinding roller 11 can accurately move to the wheel hub angle weld, so that the grinding roller 11 can accurately grind the wheel hub angle weld, thereby avoiding the grinding equipment from being difficult to accurately grind the wheel hub angle weld, resulting in poor equipment use effect;

[0033] The anti-slip assembly includes a slide bar 15, which is slidably installed on the inner walls of the two sliding holes of the cross plate 10. A disc 16 is fixed on the right side of the slide bar 15, and a spring 17 is fixed on the left side of the disc 16. The end of the spring 17 away from the disc 16 is fixed to the right side of the cross plate 10. A butt plate 18 is fixed on the left side of the slide bar 15, and a round head 19 is fixed in the middle of the left side of the butt plate 18. The round hole of the short column 5 is on the movement trajectory of the round head 19. The round head 19 is slidably connected to the round hole of the short column 5. A gap is left between the butt plate 18 and the cross plate 10. The butt plate 18 is on the right side of the wheel hub to limit the wheel hub and prevent the wheel hub from accidentally detaching from the grinding equipment during the grinding process and causing damage to the wheel hub.

[0034] When in use, the operating table 1 supports the motor 3, and the motor 3 supports the chuck 4. The staff slides the wheel hub onto the short column 5 of the chuck 4 and starts the chuck 4. The chuck 4 clamps and fixes the wheel hub, and the motor 3 on the operating table 1 is started. The motor 3 shaft starts to rotate forward, and the motor 3 shaft rotates forward in the L-shaped plate 2. The motor 3 shaft drives the chuck 4 to rotate forward, and the chuck 4 drives the wheel hub to rotate forward. Because the equipment is in the process of automatic grinding, it is difficult for the grinding head to align with the weld in the angle of the wheel hub. At this time, the operating table 1 supports the triangular ring frame 6, and the electric telescopic rod 9 in the triangular ring frame 6 is started. The telescopic end of the electric telescopic rod 9 moves to the left, and the telescopic end of the electric telescopic rod 9 drives the horizontal plate 10 to move left, and the horizontal plate 10 moves to the left. The plate 10 drives the grinding roller 11 to move to the left. At the same time, the operating table 1 supports the U-shaped guide rail 12. The horizontal plate 10 drives the inclined frame 13 to move to the left. The inclined frame 13 drives the roller 14 to move to the left. Under the action of friction, the roller 14 rolls in the U-shaped guide rail 12. With the support of the roller 14, the grinding roller 11 on the horizontal plate 10 moves stably to the left. At the same time, the U-shaped guide rail 12 limits the roller 14, so that the grinding roller 11 can be accurately moved to the wheel hub angle weld, so that the grinding roller 11 can accurately grind the wheel hub angle weld, thereby preventing the equipment from grinding the wheel hub angle weld poorly, thereby avoiding the problem that the grinding equipment is difficult to accurately grind the wheel hub angle weld, resulting in poor equipment use effect.

[0035] When the telescopic end of the electric telescopic rod 9 drives the cross plate 10 to move to the left, the cross plate 10 drives the sliding rod 15 to move to the left, the sliding rod 15 drives the disc 16 to move to the left, and the disc 16 drives the spring 17 to move to the left. At the same time, the sliding rod 15 drives the abutment plate 18 to move to the left, and the abutment plate 18 drives the round head 19 to move to the left. The round head 19 moves left into the circular hole of the short column 5. Since the chuck 4 is accidentally loosened during the rotation process, it is easy to cause the wheel hub to fall and be damaged, so that the abutment plate 18 is on the right side of the wheel hub, limiting the wheel hub to prevent the wheel hub from accidentally detaching from the chuck 4, thereby avoiding the problem of damage to the wheel hub caused by accidental detachment of the grinding equipment during the grinding process.

[0036] See also Figure 1-Figure 8 On the basis of the above embodiment, in another embodiment of the present invention, a collecting device 7 is provided on the inner wall of the circular hole of the inclined frame 13, and the collecting device 7 includes a U-shaped rod 71, a ring block 72, a collecting box 73 and a protrusion 74.

The collecting box 73 is fixed on the side where the four ring blocks 72 are close to each other. The collecting box 73 is located below the chuck 4, and the protrusion 74 is fixed on the front and rear bottom of the collecting box 73. The protrusion 74 is slidably mounted on the inner wall of the square mouth slide groove of the operating table 1, and the collecting box 73 is moved to the bottom of the wheel hub, so that the collecting box 73 can collect the welding slag during the grinding of the wheel hub in a centralized manner, so as to avoid the welding slag on the wheel hub falling and accumulating on the equipment during grinding, making the welding slag difficult to handle.

[0037] The collecting device 7 also includes a round block 75, a short rod 76 and a sponge roller 77. The round block 75 is fixed on the left side of the front and back sides of the collecting box 73. The short rod 76 is rotatably installed in the middle of the side where the two round blocks 75 are away from each other. The sponge roller 77 is fixed on the outer wall of the short rod 76. The sponge roller 77 is arranged on the outer wall of the roller 14. The sponge roller 77 is located above the protrusion 74. Under the action of friction, the roller 14 drives the sponge roller 77 to rotate. The sponge roller 77 rotates to erase the welding ash on the roller 14 to avoid inaccurate positioning caused by aging of the roller 14 when the grinding equipment is in use.

[0038] A scraper device 8 is arranged on the right side of the collecting device 7, and the scraper device 8 includes an inclined plate 81, a long rod 82 and a scraper 83.

The inner wall of the wheel hub is on the movement trajectory of the scraper 83. The scraper 83 sweeps out the welding slag on the wheel hub weld, so that the welding slag on the wheel hub weld will not accumulate in the wheel hub, so as to avoid the welding slag accumulating in the wheel hub when the grinding equipment is grinding, making it difficult to centrally handle the welding slag.

[0039] The scraper device 8 also includes an arc plate 84, a cylinder 85, a second spring 86, a sliding column 87, a U-shaped frame 88 and a second sponge roller 89.

Under the elastic force of the second spring 86, the second sponge roller 89 is attached to the surface of the wheel hub, so that the second sponge roller 89 wipes the welding ash on the surface of the wheel hub, so as to avoid a layer of welding ash attached to the surface of the wheel hub when the grinding device is grinding, making it difficult to clean the welding ash from the wheel hub.

[0040] While the horizontal plate 10 drives the inclined frame 13 to move to the left, the inclined frame 13 drives the U-shaped rod 71 to move to the left, the U-shaped rod 71 drives the ring block 72 to move to the left, the ring block 72 drives the collecting box 73 to move to the left, the collecting box 73 drives the protrusion 74 to move to the left, and the protrusion 74 slides to the left in the square opening slide groove of the operating table 1, so that the collecting box 73 moves to the bottom of the wheel hub, allowing the collecting box 73 to collect the welding slag during the grinding of the wheel hub, so as to prevent the welding slag from falling and accumulating on the equipment during grinding, thereby avoiding the problem of welding slag on the wheel hub falling and accumulating on the equipment during grinding, making it difficult to handle the welding slag.

[0041] While the ring block 72 drives the collecting box 73 to move to the left, the collecting box 73 drives the round block 75 to move to the left, the round block 75 drives the short rod 76 to move to the left, and the short rod 76 drives the sponge roller 77 to move to the left. During the movement of the sponge roller 77 to the left, under the action of friction, the roller 14 drives the sponge roller 77 to rotate, the sponge roller 77 drives the short rod 76 to rotate, and the short rod 76 rotates on the round block 75, so that the sponge roller 77 rotates to wipe off the welding ash on the roller 14, preventing the roller 14 from being adhered to welding ash during the movement and causing the roller 14 to age quickly, thereby avoiding the problem of inaccurate positioning caused by the aging of the roller 14 when the grinding equipment is in use.

[0042] While the ring block 72 drives the collecting box 73 to move to the left, the collecting box 73 drives the inclined plate 81 to move to the left, the inclined plate 81 drives the long rod 82 to move to the left, the long rod 82 drives the scraper 83 to move to the left, and the scraper 83 moves to the wheel hub, so that the scraper 83 sweeps out the welding slag on the wheel hub weld, so that the welding slag on the wheel hub weld will not accumulate in the wheel hub, preventing the welding slag from accumulating in the wheel hub when the equipment is grinding, thereby avoiding the problem of welding slag accumulating in the wheel hub when the grinding equipment is grinding, making it difficult to centrally handle the welding slag.

[0043] When the inclined plate 81 drives the long rod 82 to move to the left, the long rod 82 drives the arc plate 84 to move to the left, the arc plate 84 drives the cylinder 85 to move to the left, the cylinder 85 drives the spring 2 86 to move to the left, the cylinder 85 drives the sliding column 87 to move to the left, the sliding column 87 drives the U-shaped frame 88 to move to the left, the U-shaped frame 88 drives the sponge roller 2 89 to move to the left, and the sponge roller 2 89 contacts the wheel hub during the process of moving to the left. When the scraper 83 moves into the wheel hub, the sponge roller 2 89 is squeezed by the wheel hub. 9 Under the action of the extrusion force, the U-shaped frame 88 is driven to move rightward, and the U-shaped frame 88 drives the sliding column 87 to move rightward. The sliding column 87 slides rightward in the cylinder 85, and the spring 2 86 on the cylinder 85 begins to shrink. Under the elastic force of the spring 2 86, the sponge roller 2 89 is attached to the surface of the wheel hub, so that the sponge roller 2 89 wipes the welding ash on the surface of the wheel hub to prevent the welding ash from adhering to the surface of the wheel hub, thereby avoiding the problem that a layer of welding ash is attached to the surface of the wheel hub when the grinding device is grinding, making it difficult to clean the welding ash from the wheel hub.
