DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See Figures 1 to 4This embodiment discloses a wheel hub positioning device, including a base 100, on which a first abutting block 101 and a second abutting block 102 are mounted, which move in opposite directions. The first abutting block 101 is mounted with a first movable roller 200 that can move in its radial direction, and the second abutting block 102 is mounted with a second movable roller 201 that can move in its radial direction. A movable adjusting roller 300 is mounted between the first abutting block 101 and the second abutting block 102. A buffer pad 400 is sleeved on the outer side of the first abutting block 101 and the second abutting block 102. The buffer pad 400 passes through the first movable roller 200, the adjusting roller 300, and the second movable roller 201 so that it is at least partially in contact with the first abutting block 101 and the second abutting block 102. The first abutting block 101 and the second abutting block 102 are driven to move by a motor. The buffer pad 400 is an annular structure as a whole. After being sleeved on the first abutting block 101 and the second abutting block 102, it is guided by the first movable roller 200 and the second movable roller 201 into the gap formed between the first abutting block 101 and the second abutting block 102, and then sleeved on the adjusting roller 300 located between the first abutting block 101 and the second abutting block 102. The first movable roller 200 and the second movable roller 201 can extend outward as the distance between the first abutting block 101 and the second abutting block 102 increases. The adjusting roller 300 can dynamically balance the length of the portion of the buffer pad 400 located in the gap formed between the first abutting block 101 and the second abutting block 102 through its own movement, thereby ensuring that the buffer pad 400 fits closely with the first abutting block 101 and the second abutting block 102, so that the buffer pad 400 can form an arc-shaped structure as much as possible, ensuring that the buffer pad and the wheel hub can fit tightly and prevent slipping between the two. The buffer pad 400 is made of rubber and can reduce the extrusion damage and scratches to the wheel hub when it fits with the wheel hub.

[0022] Both the first abutting block 101 and the second abutting block 102 are provided with a second movable groove 120. A second movable block 121 is disposed within the second movable groove 120 and is capable of moving along the second movable groove 120. The second movable block 121 is connected to a connecting rod 123 that extends to the outside of the first abutting block 101 or the second abutting block 102. The first movable roller 200 and the second movable roller 201 are mounted on the ends of the connecting rod 123. A second spring 122 is disposed within the second movable groove 120 and pushes the second movable block 121 toward the inside of the first abutting block 101 or the second abutting block 102. At the same time, the first abutment block 101 and the second abutment block 102 are both provided with a telescopic groove 130, the telescopic groove 130 is connected with the second movable groove 120, and a telescopic rod 131 capable of telescoping in the vertical direction is provided in the telescopic groove 130. The telescopic rod 131 extends into the second movable groove 120, and the second movable block 121 is provided with a first inclined surface 1211. The telescopic rod 131 abuts against the first inclined surface 1211 to drive the second movable block 121 to move.

[0023] When the first abutting block 101 or the second abutting block 102 moves away from each other, the telescopic rod 131 moves upward, abuts against the first inclined surface 1211, and moves along the first inclined surface 1211, thereby pushing the second moving block 121 toward the outside of the first abutting block 101 or the second abutting block 102. As a result, at least four points of the buffer pad 400 are pushed outward, causing the buffer pad 400 to continuously expand so that it can fit the wheel hub. When the first abutting block 101 or the second abutting block 102 moves toward each other, the telescopic rod 131 moves downward, causing the buffer pad 400 to contract.

[0024] The sidewall of the telescopic slot 130 defines a guide slot 140. The telescopic rod 131 is provided with a guide block 132 embedded in the guide slot 140. The guide slot 140 is provided with a third spring 141 that abuts the guide block 132. The third spring 141 pushes the guide block 132 in a direction away from the second movable slot 120. The base 100 is provided with a guide plate 160 that extends along the movement direction of the first abutting block 101 and the second abutting block 102. The first abutting block 101 and the second abutting block 102 both define a guide slot 150 for the guide plate 160 to pass through. The telescopic rod 131 abuts the guide plate 160. The guide plate 160 is provided with a second inclined surface 161, which the telescopic rod 131 abuts against. The movement of the first abutting block 101 or the second abutting block 102 drives the telescopic rod 131 along the second inclined surface 161, thereby driving the movement of the telescopic rod 131.

[0025] When the first abutting block 101 or the second abutting block 102 moves away from each other, the first abutting block 101 or the second abutting block 102 moves, driving the telescopic rod 131 to move. At this time, the telescopic rod 131 moves upward under the push of the second inclined surface 161. At this time, the third spring 141 is compressed, and at the same time, it also pushes the second moving block 121 to move toward the outside of the first abutting block 101 or the second abutting block 102.

[0026] When the first abutment block 101 or the second abutment block 102 approaches each other, the movement of the first abutment block 101 or the second abutment block 102 drives the telescopic rod 131 to move. At this time, the telescopic rod 131 moves downward under the push of the third spring 141, and at the same time, the second moving block 121 moves toward the center of the first abutment block 101 or the second abutment block 102 under the push of the second spring 122.

[0027] The base 100 is provided with a first movable groove 103, in which a first movable block 110 capable of moving along the first movable groove 103 is embedded. A first spring 111 is installed in the first movable groove 103, and the first spring 111 pushes the first movable block 110 to move toward the center of the base 100. The adjusting roller 300 is installed on the first movable block 110.

[0028] When the first movable roller 200 and the second movable roller 201 move toward the outside of the first abutment block 101 or the second abutment block 102, the buffer pad 400 is also stretched toward the outside of the first abutment block 101 or the second abutment block 102, thereby pulling the adjustment roller 300 toward the center away from the base 100. At this time, the first spring 111 is compressed, so that part of the buffer pad 400 can move to the outside of the gap formed between the first abutment block 101 and the second abutment block 102, so that the arc formed by the buffer pad 400 can be expanded, ensuring that the buffer pad 400 fits well with the first abutment block 101 or the second abutment block 102.

[0029] When the first movable roller 200 and the second movable roller 201 move toward the inner side of the first abutment block 101 or the second abutment block 102, the pulling force on the buffer pad 400 disappears, and the compressed first spring 111 is reset, so that part of the buffer pad 400 extends into the gap formed between the first abutment block 101 and the second abutment block 102, thereby reducing the arc formed by the buffer pad 400 and ensuring the fit between the buffer pad 400 and the first abutment block 101 or the second abutment block 102.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
