[0044] The connecting portion 2 is a component used to connect the sliding portion 1 and the clamping portion 3; the connecting portion 2 connects the sliding portion 1 and the clamping portion 3, so that the clamping portion 3 is fixed relative to the sliding portion 1;

[0045] The clamping jaw part 3 refers to a component used for fixing on the wheel hub; the clamping jaw part 3 enables the wheel hub clamping device to be fixed on the wheel hub in a clamping manner, and the clamping jaw part 3 is used to provide a force point for the wheel hub clamping device on the wheel hub.

[0046] The weight-reducing groove 5 refers to a groove structure used to reduce the weight of the component; the weight-reducing groove 5 is opened on the sliding part 1 and the connecting part 2. The weight-reducing groove 5 is formed by opening a groove structure on the sliding part 1 and the connecting part 2, so that the sliding part 1 and the connecting part 2 can be made thinner and lighter.

[0047] The working principle of the clamping jaw assembly provided in this embodiment is as follows:

[0048] The clamping jaw assembly is applied to the wheel hub clamping device of the four-wheel aligner; specifically, the wheel hub clamping device includes a guide assembly 4, a drive assembly and a clamping jaw assembly, wherein the clamping jaw assembly is slidably arranged on the guide assembly 4, and the drive assembly is used to drive the clamping jaw assembly to move relative to the guide assembly 4 on the guide assembly 4, and the position of the clamping jaw assembly on the guide assembly 4 is adjusted so that the wheel hub clamping device can adapt to wheels of different sizes; when the wheel hub clamping device is clamped and fixed on the wheel hub, an auxiliary calibration tool (such as a target) is fixed on the wheel hub clamping device, and the calibration information of the auxiliary calibration tool can be obtained through the detection device, thereby obtaining the positioning information of the tire.

[0049] By adopting the above technical solution, the clamping claw part 3 provides a force application point of the wheel hub clamping device on the wheel hub, so that the wheel hub clamping device is fixed on the wheel hub in a clamping manner; the sliding part 1 realizes the movement of the clamping claw assembly relative to the guide assembly 4, thereby enabling the wheel hub clamping device to adapt to wheel hubs of different sizes, thereby improving the applicability of the wheel hub clamping device; the connecting part 2 and the sliding part 1 are both provided with weight-reducing grooves 5, so that the weight of the wheel hub clamping device is reduced, which is convenient for operators to operate and carry.

[0050] In one embodiment, a reinforcing rib 51 is provided in the weight-reducing groove 5 , and the reinforcing rib 51 connects the side groove wall 52 and the bottom groove wall 53 of the weight-reducing groove 5 .

[0051] Here, it can be understood that the reinforcing rib 51 refers to a component used to improve the mechanical strength of the connecting part 2; the reinforcing rib 51 is arranged in the weight reducing groove 5, and the groove wall of the weight reducing groove 5 has a side groove wall 52 and a bottom groove wall 53, and the reinforcing rib 51 connects the side groove wall 52 and the bottom groove wall 53, so that the side groove wall 52 and the bottom groove wall 53 can both be supported by the reinforcing rib 51, thereby improving the mechanical strength of the connecting part 2 and the sliding part 1.

[0052] Specifically, the reinforcing rib 51 is perpendicular to the bottom groove wall 53 of the weight-reducing groove 5 , and the reinforcing rib 51 divides the weight-reducing groove 5 into a plurality of weight-reducing groove parts 5 , each weight-reducing groove 5 part is still a groove structure, and thus does not affect the weight-reducing effect.

[0053] By adopting the above technical solution, the reinforcing ribs 51 improve the mechanical strength of the connecting portion 2 and the sliding portion 1, so that the clamping jaw assembly is lightweight while ensuring mechanical strength.

[0054] In one embodiment, a plurality of reinforcing ribs 51 are disposed in the weight-reducing groove 5 , and the plurality of reinforcing ribs 51 are connected end to end in sequence.

[0058] By adopting the above technical solution, the arrangement of the inclined section 21 enables the first connecting section 22 to be as close to the wheel hub as possible during the four-wheel alignment detection operation, while reducing the weight of the connecting portion 2 itself, thereby ensuring the lightweight of the wheel hub clamping device.

[0059] In one embodiment, the connecting portion 2 includes two first connecting segments 22 , which extend from the inclined segment 21 in directions away from each other, and a plane where the two first connecting segments 22 are located is used to be parallel to a plane where the hub is located.

The second connecting segment 23 extends in a direction away from the inclined segment 21 .

[0065] Here, it can be understood that the second connecting section 23 refers to a section of the connecting portion 2, and the second connecting section 23 is used to set the clamping jaw portion 3, wherein the second connecting section 23 extends from the end of the first connecting section 22 that is away from the inclined section 21 along the direction away from the inclined section 21, that is, the second connecting section 23 extends outward, so that the clamping jaw portion 3 is more open, and the points of force between the clamping jaw portion 3 and the wheel hub are more widely distributed, which further improves the stability of the wheel hub clamping device when it is fixed.

[0066] By adopting the above technical solution, the distribution range of the force points of the clamping claw part 3 on the wheel hub is expanded, and the stability of the wheel hub clamping device during fixing is improved.

[0067] In one embodiment, the second connecting section 23 is provided with a disassembly hole 231 for detachably connecting with the clamping jaw portion 3 .

[0068] Here, it can be understood that the jaw portion 3 can be fixed in the disassembly hole 231 by a threaded connection or an interference fit; when the jaw portion 3 is connected to the disassembly hole 231 by a threaded connection, the jaw portion 3 is provided with an external thread, and the disassembly hole 231 is provided with an internal thread matching the external thread, so that the jaw portion 3 can be threadedly connected to the disassembly hole 231; when the jaw portion 3 is fixed to the disassembly hole 231 by an interference fit, the outer diameter of the jaw portion 3 is slightly larger than the aperture of the disassembly hole 231, so that the jaw portion 3 can be inserted into the disassembly hole 231 and fixed in the disassembly hole 231 by the force of the interference fit.

[0069] By adopting the above technical solution, the detachable connection of the clamping jaw part 3 is achieved, which makes it convenient for operators to replace the clamping jaw part 3.
