[0033] Embodiment 1

[0034] Refer to Figures 1-6 , Figure 1 where X represents the first direction and Z represents the third direction; Figure 2In the figure, Y represents the second direction and Z represents the third direction. The first embodiment of the present application provides a wheel grasping device, including: a positioning plate 40, a first clamping assembly 10, and a second clamping assembly 20. The first clamping assembly 10 is disposed on the positioning plate 40. The first clamping assembly 10 includes a first clamping plate 11 and a second clamping plate 12 that can move along the first direction to approach or separate from each other. Both the first clamping plate 11 and the second clamping plate 12 are provided with first abutting members 13 for abutting against the outer wall of the wheel. The second clamping assembly 20 is connected to the positioning plate 40 through a connecting member 90. The second clamping assembly 20 includes a third clamping plate 21 and a fourth clamping plate 22 that can move along the second direction to approach or separate from each other. The third clamping plate 21 and the fourth clamping plate 22 are both provided with an adjusting assembly 70. The adjusting assembly 70 is provided with a second abutting member 80 for abutting against the outer wall of the wheel. The adjusting assembly 70 can move along the third direction to adjust the distance between the second abutting member 80 and the first abutting member 13 in the third direction.

[0035] In this embodiment, by moving the first clamping plate 11 and the second clamping plate 12 in the direction of approaching each other, and moving the third clamping plate 21 and the fourth clamping plate 22 in the direction of approaching each other, the wheel is tightly grasped; by moving the first clamping plate 11 and the second clamping plate 12 in the direction of separating from each other, and moving the third clamping plate 21 and the fourth clamping plate 22 in the direction of separating from each other, the state of tightly grasping the wheel is released, which is convenient for grasping wheels of any specification and size by the grasping device of the embodiment of the present application, and the wheel can be automatically held in a tight state after grasping. The positioning plate 40 is used to connect to a manipulator or a lifting tool, so as to transfer the grasped wheel to the target position through the manipulator or the lifting tool. The first clamping plate 11 and the second clamping plate 12 are relatively arranged, and the third clamping plate 21 and the fourth clamping plate 22 are relatively arranged. The first clamping plate 11, the second clamping plate 12, the third clamping plate 21, and the fourth clamping plate 22 enclose a ring. The first connection line between the first clamping plate 11 and the second clamping plate 12, and the second connection line between the third clamping plate 21 and the fourth clamping plate 22 are cross-orthogonal. The third direction is the vertical direction. What is adjusted by the adjusting assembly 70 is the relative height of the second abutting member 80 in the vertical direction. When the wheel is grasped by abutting the first abutting member 13 and the second abutting member 80 against the wheel respectively, the two first abutting members 13 are at the same height, and the two second abutting members 80 are at the same height. However, when the first abutting member 13 and the second abutting member 80 abut against the wheel, the abutting positions can be at different heights so as to abut against different high positions of the wheel. Such as Figure 6As shown, the wheels are at different heights and their outer diameters may be different. If all the abutting positions are at the same height, especially when the abutting position is below the center of gravity of the wheel, the situation of wheel wobbling is likely to occur. In this embodiment, the first abutting member 13 abuts the wheel at the first height, and the second abutting member 80 abuts the wheel at the second height. The first height is different from the second height, so that the center of gravity of the wheel is between the first height and the second height, which can improve the stability of clamping the wheel. Moreover, one of the first abutting member 13 and the second abutting member 80 can be arranged at the step of the wheel in the height direction, which can prevent the abutting member from slipping on the outer wall of the wheel.

That is, by rotating the rotating shaft 50, the first rack 31, the second rack 32, the third rack 33, and the fourth rack 34 are driven to move simultaneously, and no additional power structure needs to be provided, making the structure more compact. The moving distances of the first rack 31, the second rack 32, the third rack 33, and the fourth rack 34 are the same. Preferably, the distance between the first clamping plate 11 and the second clamping plate 12 is the same as the distance between the third clamping plate 21 and the fourth clamping plate 22.
