[0032] The hub clamp device of this embodiment comprises two gripper assemblies 1 for clamping to the hub, a guide assembly 2 slidably connected to the two gripper assemblies 1 and enabling the gripper assembly 1 to move relative to the guide assembly 2, a drive assembly 3 operably connected to the two gripper assemblies 1 and for driving the two gripper assemblies 1 to move toward or away from each other to a target position on the guide assembly 2, and a fixing assembly 4 provided on the guide assembly 2 and positioned between the two gripper assemblies 1 for fixing an auxiliary calibration tool.

[0033] As can be understood here, the gripper assembly 1 refers to an assembly fixed to the hub in a clamping manner, the number of gripper assemblies 1 is two, and the two gripper assemblies 1 are slidably connected to the guide assembly 2, i.e., the gripper assembly 1 can move relative to the guide assembly 2 in the guide assembly 2, and at the same time, the two gripper assemblies 1 can move opposite to or away from each other in the guide assembly 2 to accommodate hubs of different sizes.

[0034] The guide assembly 2 refers to an assembly for guiding the gripper assembly 1 to move along a predetermined direction, and the guide assembly 2 is slidably connected to the gripper assembly 1 so that the gripper assembly 1 can move relative to the guide assembly 2 in the guide assembly 2, and in this embodiment, the guide assembly 2 has an axial direction, and the gripper assembly 1 is guided by the guide assembly 2 to move along the axial direction of the guide assembly 2.

[0036] The fixing assembly 4 refers to an assembly for fixing an auxiliary calibration tool, and the fixing assembly 4 is provided on the guide assembly 2 and located between the two gripper assemblies 1, thus the position of the fixing assembly 4 relative to the guide assembly 2 is fixed and does not affect the toward or away movement of the guide assembly 2.

[0037] The operating principle of the hub clamp device according to this embodiment is as follows.

[0038] The distance between the two gripper assemblies 1 is adjusted according to the size of the hub to be clamped; specifically, the drive assembly 3 drives the two gripper assemblies 1 to move toward or away from each other so that the distance between the two gripper assemblies 1 matches the dimensions of the hub; the two gripper assemblies 1 are then clamped to the hub; a fixed assembly 4 is provided on the guide assembly 2 and positioned between the two gripper assemblies 1; i.e., if an auxiliary calibration tool is provided on the fixed assembly 4, it is positioned between the two gripper assemblies 1; and the detection device analyzes the positioning information of the tire by obtaining information (e.g., image information) of the auxiliary calibration tool.

[0039] By adopting the above technical solution, the drive assembly 3 can adjust the positions of the two gripper assemblies 1 in the guide assembly 2, and the two gripper assemblies 1 can be clamped to the hub, which is convenient to operate, and the distance between the two gripper assemblies 1 is adjustable, which allows the hub clamping device to adapt to hubs of different sizes, thereby improving the applicability of the hub clamping device.

Thus, when the screw shaft 31 rotates, the two gripper assemblies 1 move opposite to each other or away from each other along the axial direction of the screw shaft 31.

[0046] By adopting the above technical solution, the rotation of the screw shaft 31 around its axis can drive the gripper assembly 1 to move along the axial direction of the screw shaft 31, that is, the screw shaft 31 and the gripper assembly 1 are connected by a screw method, which makes the transmission reliable and improves the adjustment flexibility at the same time.

Thus, the guide structure 23 guides the gripper assembly 1 to move along the axial direction of the guide tube 22, and the guide structure 23 restricts the gripper assembly 1 from rotating around the axis of the guide tube 22.

[0052] Preferably, the number of guide structures 23 is multiple, and the multiple guide structures 23 are arranged parallel to and spaced apart on the outer wall of the guide tube 22, and the multiple guide structures 23 together limit rotation of the gripper assembly 1 around the axis, and preferably, the number of guide structures 23 is three, and the three guide structures 23 are arranged parallel to and spaced apart on the outer wall of the guide tube 22.

[0058] Specifically, the scale structures are arranged sequentially along the longitudinal direction of the guide tube.

[0059] By adopting the above technical solution, the convenience of using the hub clamp device is improved.
