Description

Technical Field

[0001] The utility model relates to the technical field of hub fixtures, in particular to an adjustable hub fixture. Background Technique

[0002] With the rapid development of the national economy and the continuous improvement of the scientific and technological level, the automotive field in China has developed rapidly. Among them, the automotive hub is one of the parts inside the vehicle. During the processing of automotive hubs, fixtures are often required to limit their positions.

[0003] In order to better clamp and limit the automotive hub, the Chinese utility model patent with the publication number of "CN214603767U" discloses an adjustable hub grinding fixture, including a base, a workbench, a hub main body and a support plate. A workbench is arranged at the bottom end of the base. A rotating mechanism is installed at the middle position inside the base. A support plate is arranged at the top end of the base, and a hub main body is arranged at the top end of the support plate. Clamping structures are installed on both sides of the top end of the support plate. The utility model realizes the convenient rotation of the hub main body through the setting of the rotating mechanism. When rotating, start the servo motor, and the output end of the servo motor will drive the turntable to rotate. The turntable will drive the support plate at the top to rotate. The support plate will drive the hub main body to rotate. At the same time, the support plate will drive the pulleys at the bottom end to slide inside the chute, increasing the guiding property of the support plate during rotation, facilitating the rotation of the hub main body, and enabling multi-angle and all-round grinding and processing of the hub main body.

[0004] However, in actual use, we found that when the above-mentioned scheme clamps the rim position of the outer ring of the hub through the arc-shaped clamping plate and the spring, this clamping method often cannot completely fit the arc-shaped clamping plate with the rim of the outer ring of the hub when facing hubs with different diameters, and its adaptability in clamping is poor. At the same time, when it is necessary to process the other side of the hub, the above-mentioned clamping mechanism cannot flip the hub, which is likely to affect the subsequent processing efficiency. Therefore, how to solve these problems is what we need to consider. Content of the Utility Model

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose an adjustable hub fixture. In view of the clamping problem, a rotation limiting mechanism is set, which can realize the stable limiting of the hub, cooperate with the first motor and the second motor to drive the hub to rotate, facilitate subsequent multi-angle processing, and can also replace the first limiting component and the second limiting component, so as to adapt to clamping different categories of hubs.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Referring to Figures 1 - 5 , an adjustable wheel hub fixture includes a workbench 1. Four support legs are fixedly connected to the lower end of the workbench 1. A first motor 2 is installed at the lower end of the workbench 1. A first rotating shaft 3 is vertically penetrated through the workbench 1. The lower end of the first rotating shaft 3 is fixedly connected to the output shaft of the first motor 2. The upper end of the first rotating shaft 3 is fixedly connected to a circular rotating plate 4. By rotating the circular rotating plate 4, the limited wheel hub can be driven to rotate, thus facilitating subsequent multi-angle processing. Two rollers 18 are installed at the lower end of the circular rotating plate 4. The two rollers 18 can assist the circular rotating plate 4 to rotate. Two side plates 5 are fixedly connected to the upper end of the circular rotating plate 4;

[0023] Among them, it further includes a rotation limiting mechanism. The rotation limiting mechanism includes a second motor 6. The second motor 6 is installed on the left side of the left side plate 5. The opposite sides of the two side plates 5 are both rotatably connected with a second rotating shaft 7. The left end of the second rotating shaft 7 on the left side penetrates through the corresponding side plate 5 and is fixedly connected with the output shaft of the second motor 6. The right end of the second rotating shaft 7 on the left side is fixedly connected with a first mounting bracket 8. The left end of the second rotating shaft 7 on the right side is fixedly connected with a connecting plate 9. Two telescopic rods 10 are installed on the left side of the connecting plate 9. Both of the two telescopic rods 10 are electric telescopic rods. A replaceable battery (not shown) that can supply power to the two telescopic rods 10 is arranged in the connecting plate 9. The telescopic ends of the two telescopic rods 10 are jointly fixedly connected with a second mounting bracket 11. A first limiting component is installed on the right side of the first mounting bracket 8. A second limiting component is installed on the left side of the second mounting bracket 11;

[0024] Among them, the first limiting component includes a first limiting plate 12 arranged on the right side of the first mounting bracket 8. Five limiting columns 13 are fixedly connected to the right end of the first limiting plate 12. The first limiting plate 12 and the first mounting bracket 8 are fixedly connected through three first limiting screw rods 14. The second limiting component includes a second limiting plate 15 arranged on the left side of the second mounting bracket 11. Five limiting grooves 16 are opened at the left end of the second limiting plate 15. The five limiting columns 13 are all matched with the corresponding limiting grooves 16. When clamping the hub, the five limiting columns 13 will respectively penetrate through the corresponding limiting grooves 16, so as to complete the clamping and limiting of the hub. The second limiting plate 15 and the second mounting bracket 11 are fixedly connected through three second limiting screw rods 17.

[0025] In the present utility model, during use, first, align the multiple bolt holes on the hub to be clamped with the multiple limiting columns 13 and insert them, so that the right ends of the multiple limiting columns 13 completely penetrate through the corresponding bolt holes. Then, control the two telescopic rods 10 to drive the second mounting bracket 11 to move leftward, driving the second limiting plate 15 to move leftward until it fits tightly with the hub. At this time, the right ends of the multiple limiting columns 13 will penetrate and extend into the corresponding limiting grooves 16, thus completing the limiting of the hub. The whole process is convenient and fast;

[0026] After completing the limiting operation, the first motor 2 can be controlled to drive the first rotating shaft 3 to rotate, driving the circular rotating plate 4 to rotate, thereby driving the hub to rotate around the vertical center line at the upper end of the circular rotating plate 4. At the same time, the second motor 6 can also be controlled to drive the second rotating shaft 7 to rotate, driving the first mounting bracket 8 to rotate, driving the first limiting plate 12 to rotate, thereby driving the hub to rotate around the horizontal center line on the right side of the first limiting plate 12. The above two rotation methods facilitate the subsequent multi-angle processing of the hub by the staff;

[0027] It is worth mentioning that when it is necessary to clamp wheels of different categories, appropriate first limiting components and second limiting components can be selected according to the positions and sizes of the bolt holes on the new wheel. First, remove a plurality of first limiting screws 14 to release the connection between the first mounting frame 8 and the old first limiting component, and then install the new first limiting component onto the first mounting frame 8 through the plurality of first limiting screws 14. Similarly, remove a plurality of second limiting screws 17 and install the new second limiting component onto the second mounting frame 11. In this way, the wheels of different categories can also be quickly and adaptively limited.

[0028] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
