DETAILED DESCRIPTION

[0033] ​​The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of the present application.

[0034] With reference to Figures 1-3 The utility model provides an embodiment: a kind of wheel hub unit assembly performance test equipment, including detection table 1, detection table 1 side fixedly connected with control cabinet 2, the effect of control cabinet 2 is to facilitate user to carry out debugging control to equipment, detection table 1 top fixedly connected with detection frame 3, detection frame 3 side is provided with limit component, limit component is used to limit wheel hub quickly;

[0035] Limit component includes fixed disc 4, fixed disc 4 side is fixedly connected in detection frame 3 side, the effect of fixed disc 4 in limit component is to provide support and connection for limit component, guarantee the movement stability of limit component, fixed disc 4 other side is fixedly connected with protective shell 5, the effect of protective shell 5 is to provide protection for cylinder 6, protective shell 5 is fixedly connected with cylinder 6 inside, the effect of cylinder 6 is to provide power output for limit component, guarantee that limit component can respond quickly, cylinder 6 output end is fixedly connected with transmission disc 7, transmission disc 7 outer wall is fixedly connected with multiple fixed frame 8, multiple fixed frame 8 are all slidingly connected with support rod 9 inside, support rod 9 one end is all slidingly connected with support plate 10, the effect of support plate 10 is in contact with wheel hub inner wall, and the quick limit of wheel hub is realized by the effect of multiple support plate 10, and it can adapt to wheel hub of different diameter size, so that wheel hub always remains in central position, protective shell 5 outer wall is fixedly connected with multiple connecting blocks 11 of up and down multiple times, multiple connecting blocks 11 are all slidingly connected with transmission rod 12 inside, the effect of transmission rod 12 is to further provide support for support plate 10, guarantee that support plate 10 can be supported by multiple points, to further guarantee the support stability of support plate 10, transmission rod 12 other end is all slidingly connected in support plate 10 inner wall, detection table 1 top is provided with protection component, its effect is to prevent wheel hub parts splashing, foreign matter intrusion and noise diffusion during testing process, to avoid personnel injury.

[0036] Specifically, when high precision, non-damage clamping of the wheel hub unit assembly is required, to avoid deformation of the wheel hub caused by uneven clamping force in traditional external clamping, and fast positioning is required to improve test efficiency, the user can first perform rapid debugging of the equipment through the control cabinet 2 to ensure that the equipment is in the appropriate working state. Next, the operator aligns the inner wall of the wheel hub with the support plate 10, starts the air cylinder 6, and drives the transmission disc 7 to move forward and backward through the output end, the movement of the transmission disc 7 in turn drives the support rod 9 to deflect, causing one end of the support rod 9 to rotate in the fixed frame 8 and the other end to rotate on one side of the support plate 10. This movement provides outward support for the support plate 10, ensuring that the support plate 10 is tightly aligned with the inner wall of the wheel hub. During the movement of the support plate 10, the transmission disc 7 not only drives the support rod 9 to deflect, but also drives the transmission rod 12 inside the connecting block 11 to rotate synchronously, thereby ensuring that the support plate 10 provides more uniform support force. In addition, the equipment can also adapt to different inner diameter sizes of the wheel hub, further improving its applicability and flexibility.

[0037] With reference to Figure 4 and Figure 5 , the protection assembly includes a support frame 13 and a protective cover 14. The support frame 13 is slidingly connected to the top of the detection table 1, and the outer wall of the protective cover 14 is fixedly connected to one side of the support frame 13. The protective cover 14 prevents parts from splashing and debris from flying during high-speed rotation or pressure testing of the wheel hub unit assembly, protecting the safety of the operator and preventing external dust and debris from entering to affect test accuracy. The detection table 1 has left and right symmetrical clamping grooves 20. The clamping grooves 20 cooperate with the limiting balls 21 to achieve the functions of quick locking and unlocking of the protective cover 14. The support frame 13 has left and right symmetrical fixed blocks 15 fixedly connected to the upper surface. The fixed blocks 15 have transmission shafts 16 slidingly connected inside. The transmission shafts 16 have pull rings 17 fixedly connected to the top ends. The pull rings 17 are made of rubber, which facilitates the movement of the transmission shafts 16 and increases the friction between the pull rings 17 and the hands of the user to prevent the hands from slipping. The fixed blocks 15 have connecting columns 18 fixedly connected to the bottom. The connecting columns 18 have multiple limiting balls 21 slidingly connected inside. The limiting balls 21 fit into the clamping grooves 20. The transmission shafts 16 have extrusion discs 19 fixedly connected to the outer wall. The extrusion discs 19 extrude the limiting balls 21 to make the limiting balls 21 fit into the clamping grooves 20 and limit the movement of the limiting balls 21. The outer wall of the extrusion disc 19 is in contact with the outer wall of the limiting ball 21. The transmission shafts 16 have extrusion plates 22 fixedly connected to the outer wall. The transmission shafts 16 have springs 23. The springs 23 provide elastic support for the assembly to ensure that the assembly can quickly reset after movement, thereby ensuring the stability of the movement of the assembly. One end of the spring 23 is fixedly connected to the inner wall of the fixed block 15, and the other end is fixedly connected to the upper surface of the transmission shaft 16.

[0038] Specifically, in order to protect the safety of the operator, the protective cover 14 is used to shield the hub and other moving parts, and the protective cover 14 is always kept in the effective position during use to prevent the operator from accidentally contacting the moving parts during operation. In order to facilitate the disassembly of the protective cover 14, the operator only needs to pull the pull ring 17, and under the action of the pulling force, the pull ring 17 pushes the transmission shaft 16 to slide inside the fixed block 15, thereby driving the extrusion piece 22 and the extrusion disc 19 to move upwards. In this process, the extrusion spring 23 will be elastically deformed and store elastic potential energy. When the extrusion disc 19 moves upwards, the limiting ball 21 will be released, and the limiting ball 21 will be free to slide inside the connecting column 18, thereby achieving the unlocking of the protective cover 14. After unlocking, the operator can quickly remove the protective cover 14 to install and detect the hub. After installation is completed, only the elastic restoring force of the spring 23 is needed to reset the extrusion disc 19, thereby extruding the limiting ball 21 again and clamping it into the clamping groove 20 inside, completing the locking, thereby not only optimizing the operation process, but also enhancing the safety and reliability of the equipment.

[0039] Working principle: when using the hub unit assembly performance test equipment, first, the user can quickly debug the equipment through the control cabinet 2, and then the hub inner wall is attached to the support plate 10, the transmission disc 7 is driven by the output end of the air cylinder 6 to move forward and backward, the transmission disc 7 further drives one end of the support rod 9 to rotate inside the fixed frame 8 and one end of the support plate 10 to rotate on one side of the support plate 10, thereby causing the support rod 9 to deflect and providing outward support force for the support plate 10, driving the support plate 10 to tightly attach to the hub inner wall. The support plate 10 moves while driving the transmission rod 12 to rotate and deflect inside the connecting block 11, thereby providing more uniform support force for the support plate 10, thereby achieving the effect of quickly positioning the hub, and being suitable for different inner diameters of the hub. At the same time of detection, the hub and other moving parts are covered by the protective cover 14 to ensure the safety of the operator. By pulling the pull ring 17 by the operator, the transmission shaft 16 will slide inside the fixed block 15 under the action of the pulling force, and the extrusion piece 22 and the extrusion disc 19 will slide upwards under the action of the transmission shaft 16, and the spring 23 will be elastically deformed and store elastic potential energy. When the extrusion disc 19 moves upwards, the limiting ball 21 will be released, and the limiting ball 21 will be free to slide inside the connecting column 18, thereby achieving the unlocking of the protective cover 14. After unlocking, the operator can quickly remove the protective cover 14 to facilitate the user to install and detect the hub. During installation, only the elastic restoring force of the spring 23 is needed to reset the extrusion disc 19, thereby extruding the limiting ball 21 and limiting the limiting ball 21, and clamping it into the clamping groove 20 inside to lock.

[0040] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
