[0043] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0044] like Figures 1 to 7As shown, this utility model provides a disc position adjustment device for fixing, lifting, and rotating discs. The disc position adjustment device includes a base 1, a lifting drive component 2, a rotation drive assembly 4, and a fixing assembly 6. The lifting drive component 2 is mounted on the base 1, and a lifting plate 3 is provided at the output end of the lifting drive component 2, which can drive the lifting plate 3 to rise and fall. The rotation drive assembly 4 is mounted on the lifting plate 3, and a support frame 5 is provided at the output end of the rotation drive assembly 4 to place the disc. The fixing assembly 6 includes a fixing drive component 61 and a fixing claw 62. The fixing drive component 61 is located at the output end of the rotation drive assembly 4, and the fixing claw 62 is located at the output end of the fixing drive component 61. The fixing claw 62 passes through the support frame 5 so that it can extend into the center hole of the disc placed on the support frame 5. The fixing drive component 61 can drive the fixing claw 62 to fix the disc.

[0045] By placing the wheel disc on the support frame 5 and inserting the fixing claw 62 into the center hole of the wheel disc, the fixing claw 62 can then be driven by the fixing drive component 61 to fix the wheel disc. Subsequently, the rotation and lifting of the wheel disc can be driven by the rotation drive component 4 and the lifting drive component, thereby completing the fixing, lifting and rotating of the wheel disc in one device. This eliminates the need to transfer the wheel disc to multiple workstations, improves maintenance accuracy, and reduces the transfer process and intensity.

[0046] like Figure 1 and Figure 4 As shown, in some embodiments, the disc position adjustment device further includes a non-powered synchronizer 7, which is connected to the base 1 and the lifting plate 3, thereby enabling the lifting plate 3 to be lifted smoothly during the lifting process, ensuring the stability of the load.

[0047] For example, the non-powered synchronizer 7 includes multiple mounting seats 71, which are fixed circumferentially on the base 1. A support rack 72 is inserted into the mounting seat 71. The support rack 72 can be raised and lowered relative to the mounting seat 71. A pad 73 is provided on the top of the support rack 72. The lifting plate 3 is fixed on the pad 73. A transmission rod 74 is connected between adjacent mounting seats 71. Gears are provided at both ends of the transmission rod 74. The two gears mesh with the support racks 72 on two adjacent mounting seats 71 respectively. Thus, when the lifting drive 2 drives the lifting plate 3 to rise and fall, the meshing of the support rack 72 and the gears can ensure the lifting synchronization.

[0048] like Figure 1 and Figure 5As shown, in some embodiments, to facilitate the installation of the lifting drive component 2 and ensure a more compact overall structure, the base 1 includes an upper mounting plate 11 and a lower mounting plate 12. The upper mounting plate 11 and the lower mounting plate 12 are fixed at intervals by support beams. The lower mounting plate 12 is provided with mounting holes and is fixed to the ground or other auxiliary mechanisms by fasteners such as anchors or bolts passing through the mounting holes. The auxiliary mechanisms can be, but are not limited to, cleaning seats or maintenance racks. The upper mounting plate 11 is provided with through holes 13, and the lifting drive component 2 is fixed to the lower mounting plate 12 and connected to the lifting plate 3 through the aforementioned through holes 13, thereby making the overall structure more compact.

[0049] like Figure 1 As shown, in some embodiments, the rotary drive assembly 4 includes a drive unit 41 and a rotary support 42. The rotary support 42 can be a conventional rotary support, i.e., the rotary support 42 adopts a ring structure, which includes a fixed end and a rotating end. The fixed end of the rotary support 42 is fixed to the lifting plate 3, while the fixing assembly 6 and the support frame 5 are fixed to the rotating end of the rotary support 42. The drive unit 41 is connected to the rotating end of the rotary support 42, and drives it to rotate relative to the fixed end of the rotary support 42. Exemplarily, the drive unit 41 can be a motor.

[0050] like Figure 3 As shown, in order to facilitate the wiring of the fixed component 6, the disc position adjustment device also includes a pneumatic slip ring 8. The pneumatic slip ring 8 is existing technology, and its specific structure will not be described in detail. The fixed part of the pneumatic slip ring 8 is connected to the lifting plate 3, and the rotating part of the pneumatic slip ring 8 is fixed to the rotating end of the rotary support 42. Thus, the electrical circuit of the fixed component 6 is connected to the external power supply through the pneumatic slip ring 8, thereby reducing rotational interference.

[0051] like Figure 7 As shown, in some embodiments, the support frame 5 includes a support base plate 51, a support top plate 53, and support legs 52. The support base plate 51 is fixed to the rotating end of the rotary support 42. A fixed drive member 61 is disposed on the support base plate 51. Multiple support legs 52 are circumferentially disposed on the support base plate 51, surrounding the fixed drive member 61. The support top plate 53 is fixed to the support legs 52 for support. The support top plate 53 is provided with a through hole 54 for the fixing claw 62 to pass through, so that when the wheel disc is placed on the support top plate 53, the fixing claw 62 can extend into the center hole of the wheel disc. In the current embodiment, the support base plate 51 is provided with a wire hole to facilitate the routing of wires for the fixed drive member 61.

[0052] like Figure 6As shown, in some embodiments, the fixing claw 62 includes multiple fixing sub-claws arranged circumferentially at the output end of the fixing drive member 61. The fixing drive member 61 can drive the multiple fixing sub-claws to move closer or further apart, so that when the fixing sub-claws move closer together, the wheel disc can be placed on the support top plate 53; subsequently, the fixing sub-claws are driven to move further apart, pressing against the inner ring of the wheel disc and fixing it. Exemplarily, the fixing drive member 61 uses a multi-jaw chuck, for example, with three fixing sub-claws, the fixing drive member 61 uses a three-jaw chuck. In addition, the fixing method of the multiple fixing sub-claws also has an alignment function, making the wheel disc placement more accurate.

[0053] In some embodiments, a guide slope 621 is provided on the top outer side of the fixed claw. The height of the guide slope 621 gradually decreases outward from the center surrounded by multiple fixed claws. This allows the wheel disc to be guided by the guide slope 621, making it easier for the fixed claw to enter the inner ring of the wheel disc. At the same time, the guide slope 621 can also reduce damage to the wheel disc when it contacts the wheel disc.

[0054] Specifically, the fixed claw includes a fixed block 622 and a nylon guide block 623. The fixed block 622 is fixed to the output end of the fixed drive member 61, and the nylon guide block 623 is fixed on the fixed block 622. The guide slope 621 is formed on the nylon guide block 623, thereby making it more wear-resistant.

[0055] like Figure 1 and Figure 2 As shown, in some embodiments, the disc position adjustment device further includes a zeroing sensor 9 and a reference component 10. One of the zeroing sensor 9 and the reference component 10 is disposed on the lifting plate 3, and the other is disposed at the output end of the rotary drive assembly 4. On the one hand, the zeroing sensor 9 can realize the daily calibration of the rotary drive assembly 4, and on the other hand, the zeroing sensor 9 can record the number of rotations, providing data support for disc detection. In the current embodiment, the zeroing sensor 9 is disposed on the lifting plate 3, while the reference component 10 is disposed on the support base plate 51.

[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
