The limit blocks 6 are fixedly connected to the frame plate 5, and each limit block 6 is evenly distributed on each edge of the top surface of the frame plate 5, so that the limit blocks 6 are evenly distributed on the frame plate 5.

[0027] A limiting slide 7 is provided between the two limiting blocks 6, and the limiting slide 7 is located exactly on the two diagonal lines of the top surface of the limiting block 6. The limiting slide 7 can cooperate with the push plate 8 during the upward movement of the jacking column 11, so that the push plate 8 moves outward in the limiting slide 7, and the stroke is limited, and it can only move within the limiting slide 7.

[0028] The limiting slide 7 is provided with a push plate 8 extending to the inside of the wheel hub 3. The push plate 8 is moved to the inside of the wheel hub 3, and the positioning plate 9 is driven to move, expand and support toward the inner wall of the wheel hub 3 through the movement of the push plate 8.

[0029] A positioning plate 9 is provided on the side of the push plate 8 close to the inner wall of the hub 3. The cross section of the positioning plate 9 is arc-shaped and is movably fitted with the inner wall of the hub 3. There are multiple positioning plates 9, which can expand from multiple directions at the same time, and fit with the inner wall of the hub 3 to fix the hub 3 from the inside, thereby improving the stability of the fixation of the hub 3 and making it easier to process the valve hole.

[0030] An inclined portion 8-1 is formed near the bottom end on the other side of the push plate 8, a cylinder 10 is provided in the frame plate 5, a telescopic rod of the cylinder 10 is connected to a lifting column 11, an inclined portion 11-1 is formed on the outer wall of the lifting column 11, the inclined portion 11-1 and the inclined portion 8-1 cooperate with each other, the inclinations of the inclined portion 8-1 and the inclined portion 11-1 are parallel, but the inclination length of the inclined portion 11-1 is greater than the inclination length of the inclined portion 8-1, through the cooperation between the inclined portion 8-1 and the inclined portion 11-1, when the lifting column 11 cooperates with the push plate 8, the positioning plate 9 expands outward.

[0031] The positioning plate 9 is fixedly connected to the pushing plate 8 . A rubber pad 13 is provided on one side of the positioning plate 9 close to the wheel hub 3 . The cross section of the rubber pad 13 is also arc-shaped. The rubber pad 13 can play a buffering role when the positioning plate 9 is in contact, expanded and fixed with the wheel hub 3 .

[0032] A support plate 14 is provided below the table 1, and vertically penetrating support columns 15 are provided at the four corners of the support plate 14.

[0034] Detailed usage and effects of the above embodiments:

[0035] When the valve hole needs to be processed, the valve hole is placed in the placement slot 2 on the table 1, and the cylinder 10 is started. The telescopic rod of the cylinder 10 drives the lifting column 11 to move upward, and the inclined portion 11-1 on the lifting column 11 and the inclined portion 8-1 on the pushing plate 8 contact each other. While continuing to move upward, the lifting column 11 will push the pushing plate 8 to move outward in the limiting slide 7, driving the arc-shaped positioning plate 9 to approach the inner wall of the wheel hub 3. When the positioning plate 9 expands to fix the wheel hub 3, the lifting column 11 stops rising, completing the fixation of the wheel hub 3, thereby improving the stability of the valve hole processing.

[0036] When the height of the table 1 needs to be adjusted, the motor 20 is started, and the output shaft of the motor 20 drives the bidirectional screw 18 to rotate, so that the horizontal moving block 19 moves on the bidirectional screw 18, and the steering plate 21 is rotatably connected between the horizontal moving block 19 and the table 1. When the horizontal movement moves, it drives the steering plate 21 to achieve an angle change, so that the lifting rod 16 can achieve a height change in the support column 15, and the height of the table 1 is adjusted, thereby improving the flexibility in the valve hole processing process.
