The locking module 300 can lock or unlock the synchronizing assembly 200, and the jaw assembly 400 is used to be clamped to a hub, so that the hub clamping device 900 is attached to the hub.

When the locking module 300 is in the release state, one of the jaw assemblies 400 is moved close to the locking module 300, and the synchronization assembly 200 drives the other jaw assembly 400 to be synchronized close to the locking module 300, so that the locking module 300 is always located between the two jaw assemblies 400; when the locking module 300 is in the locked state, the two jaw assemblies 400 are fixed relative to the locking module 300, and the central axis of the locking module 300 coincides with the central axis of the hub. Thus, when the hub clamping device 900 is applied to four-wheel alignment of a wheel, it can be mounted on a hub through the two jaw assemblies 400, and when the hub clamping device is mounted, the two jaw assemblies 400 can be driven to move by the synchronizing assembly 200 for the same distance, so that the locking module 300 is always located in the middle of the two jaw assemblies 400, and the central axis of the locking module 300 can be ensured to be coincident or approximately coincident with the central axis of the hub.

It will be appreciated that the coincidence of the two central axes described herein does not require that they coincide exactly, allowing for some error, i.e. the central axes may deviate by some angle, as long as the accuracy of the calculated calibration of the vehicle calibration apparatus is not affected. Alternatively, the two central axes may deviate by an angle, which is compensated by other means, such as an algorithm of calibration calculation, and the like, and the coincidence of the central axes described in this application includes the above cases.

As shown in fig. 3, the main body 100 includes a first substrate 110, a second substrate 120 and a connection post 130, the first substrate 110 and the second substrate 120 are disposed at a predetermined distance, and the connection post 130 is connected to the first substrate 110 and the second substrate 120.

It will be appreciated that the length of the connecting post 130 can be adjusted as desired by the user, simply by ensuring that two jaw assemblies 400 can be attached to the hub. It should be understood that the connection posts 130 are only for connecting the first substrate 110 and the second substrate 120, and the shape thereof is not limited to a column shape, and may be, for example, a rectangular parallelepiped shape or a square cube shape.

Thus, when the timing belt 230 rotates, the first pulley 210 and/or the second pulley 220 rotate in synchronization.

Of course, in some embodiments, the rotating shaft may be omitted, in which case, the opposite side surfaces of the two first protrusions 111 extend outwards to form two oppositely disposed protrusions (not shown), the first rotating wheel 210 is installed between the two oppositely disposed protrusions, the first rotating wheel 210 rotates around the central connecting line of the two protrusions, and similarly, the two second protrusions 121 may also be configured in the same way.

Thus, when the timing belt 230 rotates, since the portions on both sides of the center line move the same belt length and in opposite directions, it is ensured that the two jaw assemblies 400 can move closer to or farther from the locking module 300 simultaneously, and the two jaw assemblies 400 move the same distance, so that the locking module 300 is at the center of the two jaw assemblies 400.

Referring to fig. 2 and 4-6, the locking module 300 includes a mounting seat 310, a bracket 320, a locking assembly 330, and an abutting block 340, wherein the mounting seat 310 is mounted on the main body 100, the bracket 320 is mounted on the abutting block 340, the bracket 320 is movable relative to the abutting block 340, the locking assembly 330 is mounted on the mounting seat 310, and the abutting block 340 is mounted on the mounting seat 310.

The mounting seat 310 is provided with a positioning hole 311, and a central axis of the positioning hole 311 is a central axis of the locking module 300.

When the locking assembly 330 is in a locked state, the abutting block 340 and the bracket 320 clamp the timing belt 230 together, and the timing belt 230 is fixed; when the locking assembly 330 is in the elastic state, the abutting block 340 does not abut against the timing belt 230, and the timing belt 230 can drive the two jaw assemblies 400 to move.

Referring to fig. 5, the bracket 320 includes a bottom plate 321, a top plate 322, and a guide column 323, the abutting block 340 is provided with a mounting hole 343, one end of the guide column 323 passes through the mounting hole 343 and is connected to the bottom plate 321, and the other end of the guide column 323 is connected to the top plate 322, wherein a portion of the timing belt 230 is located between the bottom plate 321 and the abutting block 340, and the guide column 323 can move relative to the abutting block 340.

Referring to fig. 6 and 7, in use, when the wrench 332 is gradually rotated in a predetermined direction, the main cam 331 pushes the top plate 322 to move away from the main body 100, so that the bottom plate 321 gradually approaches the first abutting portion 341 of the abutting block 340, and the bottom plate 321 and the abutting block 340 clamp the timing belt 230 together.

It should be understood that the main cam 331 is an eccentric cam including a top surface portion, a bottom surface portion, and a connecting portion connecting the bottom surface portion and the top surface portion. The top surface portion is a portion of the main cam 331 farthest from the center, the bottom surface portion is a portion of the main cam 331 closest to the center, and a distance between an outer wall of the main cam and the center of the main cam is gradually increased in a process from the bottom surface portion to the top surface portion along the connecting portion.

In an actual use process, when the top plate 322 abuts against the bottom surface of the main cam 331, the wrench 332 is in an initial position, when the wrench 332 is gradually rotated along a predetermined direction, different positions of a connecting portion of the top plate 322 and the main cam 331 abut against each other, the top plate 322 is gradually ejected from the main body 100, that is, the top plate 322 is gradually lifted, and drives the guide post 323 and the bottom plate 321 to move along a central axis of the mounting hole 343, so that the bottom plate 321 gradually approaches the abutting block 340, after the main cam 331 rotates a certain angle along the predetermined direction, the bottom plate 321 and the first abutting portion 341 of the abutting block 340 clamp the timing belt 230 together, and at this time, the locking assembly 330 is in a locked state, and the timing belt 230 is fixed and cannot move. When the positions of the two jaw assemblies 400 need to be adjusted, the wrench 332 rotates in a direction opposite to the preset direction, the top plate 322 gradually abuts against the bottom surface of the main cam 331, and the distance between the bottom plate 321 and the abutting block 340 gradually increases, so that the synchronous belt 230 is not clamped by the bottom plate 321 and the first abutting portion 341, and at this time, the locking assembly 330 is in an elastic state, and drives the synchronous belt 230 to rotate, that is, the two jaw assemblies 400 can be driven to move, so that the positions of the two jaw assemblies 400 can be adjusted. The preset direction is a counterclockwise direction, and the direction shown in the figure is taken as a reference object.
