Specific implementation manner

[0024] As Figures 1-4 shown, the present utility model provides a technical solution: a hub processing turntable tooling, including a processing table 1, the inner wall of the processing table 1 is rotationally connected with a rotating shaft 2, and the rotating shaft 2 penetrates through the processing table 1, the top of the rotating shaft 2 is fixedly installed with a rotating table 3, the bottom of the rotating shaft 2 is fixedly installed with a worm gear 4, the bottom of the processing table 1 is fixedly installed with a motor 5, the output end of the motor 5 is fixedly installed with a worm 6, the worm 6 meshes with the worm gear 4, when the arc-shaped clamping plate 74 clamps the hub, start the motor 5 to drive the worm 6 to rotate, while the worm 6 rotates, it can drive the rotating shaft 2 to rotate in cooperation with the worm gear 4 meshing with it, when the rotating shaft 2 rotates, it will drive the rotating table 3 to rotate synchronously, and the rotation of the rotating table 3 can drive the hub clamped by the arc-shaped clamping plate 74 to rotate synchronously, so that the hub can be processed. A positioning mechanism 7 for clamping the hub is arranged on the rotating table 3, and by arranging the positioning mechanism 7, the hub can be fixed on the top of the rotating table 3, which is convenient for the staff to process the hub. An auxiliary mechanism 8 is arranged on the positioning mechanism 7, and by arranging the auxiliary mechanism 8, the stability of the hub can be further improved, and the phenomenon that the hub slides during the processing can be avoided.

[0025] The above positioning mechanism 7 includes a positioning rod 71, a cross 72, a threaded rod 73, an arc-shaped clamping plate 74, a T-shaped rod 75, an inclined groove 76, a handle 77, and a rubber pad 78; the positioning rod 71 is slidably connected to the inner wall of the turntable 3. There are four groups of positioning rods 71, and the four groups of positioning rods 71 are slidably connected to the inner wall of the turntable 3 in a circumferential array with the rotating shaft 2 as the center point. The top of the positioning rod 71 is fixedly installed with an arc-shaped clamping plate 74, and the side wall of the arc-shaped clamping plate 74 is fixedly installed with a rubber pad 78. The four groups of positioning rods 71 cooperate with the arc-shaped clamping plate 74 and the rubber pad 78 to clamp the hub, and the arc-shaped arc-shaped clamping plate 74 can make the rubber pad 78 better fit the outer wall of the hub, so as to effectively avoid the situation of the hub sliding during the processing. The bottom of the positioning rod 71 is fixedly installed with a T-shaped rod 75. The cross 72 is slidably connected to the outer wall of the rotating shaft 2, and an inclined groove 76 is opened on the cross 72. The outer wall of the T-shaped rod 75 fits the inner wall of the inclined groove 76. When the cross 72 slides upward on the outer wall of the rotating shaft 2, the inclined groove 76 will squeeze the T-shaped rod 75, causing the T-shaped rod 75 to drive the positioning rod 71 to slide on the inner wall of the turntable 3 and gradually approach the rotating shaft 2, so that the four groups of positioning rods 71 can approach each other. The threaded rod 73 is rotatably connected to the inner wall of the turntable 3, and the threaded rod 73 penetrates the turntable 3. The cross 72 is threadedly connected to the outer wall of the threaded rod 73. The top of the threaded rod 73 is fixedly installed with a handle 77. By rotating the handle 77 to rotate the threaded rod 73, the cross 72 threadedly connected thereto is driven to slide up and down on the outer wall of the rotating shaft 2.

One end of the lead screw 81 is fixedly installed with a knob 82, and the other end of the lead screw 81 is rotatably connected to a suction cup 83. After the arc-shaped clamping plate 74 clamps the outer wall of the hub, the lead screw 81 is rotated by the knob 82 to make the suction cup 83 adsorb the hub, and the suction cup 83 can be used to further improve the stability of the hub and avoid the phenomenon of the hub sliding during the processing.

[0027] Working principle: First, place the wheel hub on the turntable 3, and then rotate the threaded rod 73 through the handle 77. The rotation of the threaded rod 73 drives the cross 72 threadedly connected to it to slide upward on the outer wall of the rotating shaft 2. At the same time, the inclined groove 76 will squeeze the T-shaped rod 75, causing the T-shaped rod 75 to drive the positioning rod 71 to slide on the inner wall of the turntable 3 and gradually approach the rotating shaft 2, so that the four groups of positioning rods 71 can approach each other until the rubber pad 78 on the side wall of the arc-shaped clamping plate 74 is tightly attached to the outer wall of the wheel hub. At this time, the arc-shaped clamping plate 74 and the rubber pad 78 can be used to clamp the wheel hub, and the arc-shaped arc-shaped clamping plate 74 can make the rubber pad 78 better fit on the outer wall of the wheel hub, enabling the rubber pad 78 to fully exert its excellent friction performance, thereby effectively avoiding the situation of the wheel hub sliding during the processing and facilitating the staff to process the wheel hub.

[0028] After the arc-shaped clamping plate 74 clamps the outer wall of the wheel hub, rotate the screw rod 81 through the knob 82. Under the threaded connection between the screw rod 81 and the positioning rod 71, the screw rod 81 will drive the suction cup 83 to gradually approach the wheel hub until the suction cup 83 is tightly attached to the outer wall of the wheel hub. At this time, the suction cup 83 will adsorb the wheel hub, and the suction cup 83 can be used to further improve the stability of the wheel hub and avoid the phenomenon of the wheel hub sliding during the processing.

Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
