After the wheel hub is lifted, the stacking rod 8 is inserted into the center hole of the wheel hub, and then the stacking rod 8 is inserted into the centering mechanism 7. After the first wheel hub reaches the top position of the stacking rod 8, the electric telescopic rod 13 stops. At this time, the positioning assembly 9 is located between the wheel hub's spokes and the top of the movable cylinder 71. Then the centering mechanism 7 works in the reverse direction, disengages from the contact with the inner wall of the rim of the wheel hub, so that the wheel hub is out of the limit. At this time, the wheel hub falls to the position of the positioning assembly 9 under the action of gravity.

At this time, the block 94 of the positioning assembly 9 pops out from the movable cavity 91 under the elastic force of the spring 92. The block 94 is located between the spokes of the wheel hub and the top of the movable cylinder 71. Then the forward and reverse motor 72 rotates in the opposite direction, driving the anti-slip strip 764 of the centering assembly 76 to disengage from the inner wall of the rim of the wheel hub, so that the wheel hub is out of the limit. At this time, the wheel hub falls to the position of the block 94 under the action of gravity, and the block 94 supports and limits the wheel hub to ensure that the position of the wheel hub is fixed.

The adjusting disk 74 is slidably sleeved on the movable cylinder 71, and the top of the adjusting disk 74 and the movable cylinder 71 are respectively fixedly connected with the centering assembly 76.

[0037] Furthermore, one end of the threaded rod 73 away from the forward and reverse motor 72 is rotatably connected to a support seat 75, and the support seat 75 is fixedly connected to the outer wall of the movable cylinder 71. A movable annular groove 711 is provided at the bottom of the movable cylinder 71, and the adjustment disk 74 is slidably sleeved in the movable annular groove 711.

At the same time, in cooperation with the lower connecting rod 767, the movable bar 763 can be moved away from the movable cylinder 71 or close to the movable cylinder 71. When the movable bar 763 moves away from the movable cylinder 71, it drives the fixed anti-slip strip 764 to contact the inner wall of the rim of the wheel hub. The anti-slip strips 764 evenly distributed around the circumference drive the center hole of the wheel hub to coincide with the axis of the movable cylinder 71.

[0041] Example 3

[0042] Reference Figure 1-6, which is the third embodiment of the present invention. This embodiment is based on the above two embodiments. When in use, the wheel hub that needs to push the material for transfer is transmitted to the conveyor belt 4, the servo motor 2 is powered on and works, driving the fixed active conveying roller 3 to rotate, the active conveying roller 3 drives the conveyor belt 4 to work, and the conveyor belt 4 then drives the wheel hub to move. After the wheel hub moves to the position of the baffle 6, it is blocked and stops, the electric telescopic rod 13 works, the electric telescopic rod 13 drives the fixed plate 15 to lift, and the fixed plate 15 drives the fixed centering mechanism 7 to rise synchronously. After the centering mechanism 7 is lifted, the top of the anti-slip strip 764 of the centering assembly 76 contacts the spoke of the wheel hub, and at the same time the movable cylinder 71 does not contact the stacking rod 8, the electric telescopic rod 13 stops working, and the forward and reverse motors 72 of the centering mechanism 7 are powered on Working, the forward and reverse motors 72 drive the fixed threaded rod 73 to rotate, the threaded rod 73 drives the adjusting disk 74 to move through the threaded structure, the adjusting disk 74 drives the centering assembly 76 to work, the lower connecting rod 767 of the centering assembly 76 moves under the drive of the adjusting disk 74, the lower connecting rod 767 drives the hinged movable bar 763 to move in the direction away from the movable cylinder 71, and at the same time the movable bar 763 drives the hinged upper connecting rod 762 and the middle connecting rod 765 to move, a parallelogram is formed between the upper connecting rod 762, the middle connecting rod 765, the movable cylinder 71 and the movable bar 763, and at the same time cooperates with the lower connecting rod 767 to enable the movable bar 763 to move away from the movable cylinder 71 or close to the movable cylinder 71, and when the movable bar 763 is away from the movable cylinder 71, it drives the fixed anti-skid The strips 764 contact the inner wall of the rim of the wheel hub, and the anti-skid strips 764 evenly distributed around the circumference drive the center hole of the wheel hub to coincide with the axis of the movable cylinder 71. At this time, multiple anti-skid strips 764 support and fix the wheel hub, and then the electric telescopic rod 13 works again to drive the wheel hub to lift. After the wheel hub is lifted, the stacking rod 8 is inserted into the center hole of the wheel hub, and then the stacking rod 8 is inserted into the movable cylinder 71. After the wheel hub passes through the positioning assembly 9, the inner wall of the center hole of the wheel hub contacts the block 94, causing the block 94 to retract into the movable cavity 91. When the first wheel hub reaches the top position of the stacking rod 8, the electric telescopic rod 13 stops. At this time, the block 94 of the positioning assembly 9 pops out from the movable cavity 91 under the elastic force of the spring 92, and the block 94 is located between the spokes of the wheel hub and the top of the movable cylinder 71. The forward and reverse motors 72 then rotate in the opposite direction, driving the anti-skid strips 764 of the centering assembly 76 to disengage from the inner wall of the rim of the wheel hub, so that the wheel hub is out of the limit position. At this time, the wheel hub falls to the position of the block 94 under the action of gravity, and the block 94 supports and limits the wheel hub to ensure that the position of the wheel hub is fixed. Then the electric telescopic rod 13 retracts, and when the centering mechanism 7 retracts, the inner wall of the movable cylinder 71 always contacts the block 94, so that the block 94 is always in the movable cavity 91, avoiding the block 94 from blocking the movable cylinder 71. The electric telescopic rod 13 drives the centering mechanism 7 to move to the initial position below the surface of the conveyor belt 4 again, which is convenient for pushing and stacking the next wheel hub. When the stacking rod 8 is sequentially sleeved on the wheel hub from top to bottom, the wheel hub is transported through the conveying guide rail 10.
