Description

Technical Field

[0001] This utility model relates to the field of automotive testing equipment technology, specifically to an automotive wheel hub pressure resistance testing operating table with rapid positioning capability. Background Technology

[0002] The automotive wheel hub pressure resistance testing workbench is a commonly used piece of equipment in automotive parts testing. It is mainly used to test the pressure resistance performance of automotive wheel hubs to ensure that the wheel hubs meet strength requirements during use. It is widely used in automotive manufacturing plants, automotive repair shops, and wheel hub testing institutions.

[0003] Existing automotive wheel hub pressure resistance testing platforms, designed to meet basic limiting requirements, typically only feature a single-directional limiting structure. However, this presents significant problems in practical use: most devices cannot simultaneously achieve rapid radial and axial limiting, requiring manual adjustment of multiple components, which is cumbersome and inefficient, especially when changing to different wheel hub sizes. Furthermore, some devices lack precise positioning auxiliary structures, resulting in insufficient limiting accuracy and potential wheel hub misalignment during testing, affecting the accuracy of results. In addition, most devices lack integrated control and status feedback structures, making it impossible to monitor the limiting status in real time, requiring manual inspection and confirmation, increasing operational procedures and the risk of errors, and causing inconvenience to users. Therefore, those skilled in the art provide an automotive wheel hub pressure resistance testing platform with rapid limiting capabilities to address the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to provide a car wheel hub pressure resistance testing workbench with rapid positioning capability, thereby solving the problems in the prior art.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: a car wheel hub pressure resistance testing operating platform with rapid positioning capability, comprising an operating platform body, and a radial rapid positioning component and an axial rapid positioning component provided on the operating platform; the top surface of the operating platform body is a horizontal bearing surface, the radial rapid positioning components are installed on the top surface of the operating platform body and distributed radially, the radial rapid positioning components include at least three T-shaped guide rails that extend radially along the top surface of the operating platform body and are distributed radially, a sliding limiting block is slidably connected on the T-shaped guide rail, and a cam-type quick locking component is installed on the side of the sliding limiting block;

[0006] The axial quick-limiting component is located at the center of the top surface of the main body of the operating table. It includes an electric lifting rod fixed inside the main body of the operating table. The telescopic end of the electric lifting rod extends upward through the top surface of the main body of the operating table and is fixedly connected to the center of the bottom of the support base. The radial quick-limiting component and the axial quick-limiting component cooperate to form a double limit on the car wheel hub.

[0007] As a preferred embodiment of the above technical solution, the cam end of the cam-type quick-locking component abuts against the side of the T-shaped guide rail, and a scale is provided on the top surface of the main body of the operating table along the length of the T-shaped guide rail.

[0008] As a preferred embodiment of the above technical solution, the sliding limit block has an arc-shaped contact surface on the side facing the center of the main body of the operating table. An elastic wear-resistant layer is fixed on the surface of the arc-shaped contact surface, and the sliding limit block is in contact with the outer peripheral wall of the car wheel hub through the arc-shaped contact surface.

[0009] As a preferred embodiment of the above technical solution, the top surface of the support seat is provided with an annular positioning groove that is adapted to the center hole of the automobile wheel hub, and elastic positioning pins are symmetrically embedded in the side wall of the support seat, with the pin end of the elastic positioning pin extending into the annular positioning groove.

[0010] As a preferred embodiment of the above technical solution, the elastic positioning pin includes a sleeve that is fixedly embedded in the side wall of the support base. A spring is provided inside the sleeve. One end of the pin body abuts against the spring, and the other end can slide out of the sleeve and pass through the annular positioning groove. A guide slope is provided at the protruding end of the pin body.

[0011] As a preferred embodiment of the above technical solution, there are three sliding limit blocks, which are distributed in an equilateral triangle on the top surface of the main body of the operating table. The cam-type quick-locking component is equipped with an operating handle. Rotating the operating handle causes the cam in the cam-type quick-locking component to be in close contact with the outer wall of the T-shaped guide rail, thereby locking the sliding limit block and the T-shaped guide rail together.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention overcomes the limitations of existing devices that only limit movement in one direction by designing a dual limiting structure consisting of a radial quick-release component and an axial quick-release component. The two components work together to achieve stable positioning of the car wheel hub, effectively preventing radial offset or axial movement of the wheel hub during testing, significantly improving the reliability of the limit and ensuring the accuracy of the pressure resistance test results. The sliding cooperation between the T-shaped guide rail and the sliding limit block in the radial quick-release component, combined with the convenient operation of the cam-type quick-locking component, allows for quick adjustment to fit wheel hubs of different diameters. With the precise assistance of the scale, repeated manual calibration is unnecessary, significantly shortening the wheel hub replacement and adjustment time and improving testing efficiency.

[0014] Meanwhile, the arc-shaped contact surface of the sliding limit block increases the contact area with the outer peripheral wall of the wheel hub, further enhancing radial limit stability. The elastic wear-resistant layer can prevent scratches on the wheel hub surface during the limit process, combining protection and component wear resistance, and extending the service life of the device. The automatic lifting design of the electric lifting rod in the axial quick limit assembly is compatible with wheel hubs of different thicknesses. The guide slope of the elastic positioning pin enables automatic retraction and locking when the wheel hub is fitted, eliminating the need for additional manual operation and further simplifying the limit process.

[0021] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0022] Please see the appendix Figure 1 As shown, a rapid-limiting automotive wheel hub pressure resistance testing platform includes a platform body 1. The platform body 1 is equipped with a radial rapid-limiting component 2 and an axial rapid-limiting component 3. The top surface of the platform body 1 is a horizontal bearing surface. The radial rapid-limiting component 2 is installed on the top surface of the platform body 1 and distributed radially, while the axial rapid-limiting component 3 is located at the center of the top surface of the platform body 1. The radial rapid-limiting component 2 and the axial rapid-limiting component 3 cooperate to form a dual-limiting mechanism for the automotive wheel hub. Through the combination and cooperation of the above components, a wheel hub pressure resistance testing platform structure with dual rapid-limiting, precise positioning, and status feedback is formed.

[0023] As one implementation method in this embodiment, please refer to the appendix. Figure 1 Appendix Figure 3As shown, the radial rapid limiting assembly 2 includes three T-shaped guide rails 21 extending radially along the top surface of the main body 1 and distributed in a radial pattern. The included angle between the three T-shaped guide rails 21 is 120°, ensuring that the subsequent sliding limiting block 22 can form an equilateral triangle support structure. The T-shaped guide rails 21 are integrally formed of aluminum alloy, and their cross-section is "T"-shaped. The inside of the groove is provided with a wear-resistant coating to reduce the frictional resistance when the sliding limiting block 22 slides. The sliding limiting block 22 is slidably connected to the T-shaped guide rails 21. The sliding limiting block 22 is made of engineering plastic, which combines lightweight and high strength characteristics. Its bottom is provided with a "T"-shaped slider that matches the groove of the T-shaped guide rail 21. Wear-resistant nylon pads are embedded in the surface of the slider to further reduce sliding wear; a cam-type quick-locking component 23 is installed on the side of the sliding limit block 22. The cam-type quick-locking component 23 includes a cam, a rotating shaft and an operating handle 231. The cam is rotatably connected to the side wall of the sliding limit block 22 through the rotating shaft. The surface of the cam is hardened to improve its hardness. The cam end abuts against the side of the T-shaped guide rail 21. A scale 24 is provided on the top surface of the main body 1 of the operating table along the length of the T-shaped guide rail 21. The scale 24 is made by etching process and can cover the diameter range of most domestic car wheel hubs. The corresponding wheel hub inch specifications are marked next to the scale line, which makes it convenient for operators to quickly find the appropriate scale.

[0024] The sliding limit block 22 has an arc-shaped contact surface 221 on the side facing the center of the main body 1 of the operating table. The curvature of the arc-shaped contact surface 221 is designed according to the curvature of the outer peripheral wall of common wheel hubs, which can fit tightly with the outer peripheral wall of most standard wheel hubs. Its contact area accounts for more than 80% of the total area of ​​the sliding limit block 22 on the side facing the center, which greatly improves the stability of radial limiting. An elastic wear-resistant layer 222 is fixed on the surface of the arc-shaped contact surface 221. The elastic wear-resistant layer 222 can undergo slight deformation during limiting to fit the surface of the wheel hub, and can resist wear caused by long-term friction. The elastic wear-resistant layer 222 is fixed to the arc-shaped contact surface 221 with strong adhesive, and the edges are rounded to avoid scratching the coating layer on the surface of the wheel hub. There are three sliding limit blocks 22 arranged in an equilateral triangle on the top surface of the main body 1 of the operating table. This distribution can form a uniform radial constraint force on the hub from three directions, preventing the hub from radially shifting due to uneven force during the testing process. The cam-type quick-locking component 23 is equipped with an operating handle 231, which is a metal rod wrapped in rubber with anti-slip texture on the surface, making it easy for the operator to grip and apply force. When the operating handle 231 is rotated, the cam rotates around the axis. When the long radius end of the cam contacts the outer wall of the T-shaped guide rail 21, continuing to rotate the operating handle 231 can generate a clamping force, making the cam and the outer wall of the T-shaped guide rail 21 fit tightly, thereby locking the sliding limit block 22 and the T-shaped guide rail 21.

[0025] As one implementation method in this embodiment, please refer to Figure 2 Appendix Figure 4 and attached Figure 5 As shown, the axial quick-limiting assembly 3 includes an electric lifting rod 32 fixed inside the main body 1 of the operating table. The telescopic end of the electric lifting rod 32 extends upward through the top surface of the main body 1 of the operating table and is fixedly connected to the bottom center of the support base 31. The top surface of the support base 31 is provided with an annular positioning groove 311 adapted to the center hole of the car wheel hub. Elastic positioning pins 33 are symmetrically embedded in the side wall of the support base 31. The elastic positioning pin 33 includes a sleeve 331 fixedly embedded in the side wall of the support base 31. A spring 332 is provided inside the sleeve 331. One end of the pin 333 abuts against the spring 332, and the other end can slide out of the sleeve 331 and pass through the annular positioning groove 311. The extended end of the pin 333 is provided with a guide slope.

[0026] When the electric lifting rod 32 is activated, its telescopic end drives the support base 31 to rise to the appropriate height. The center hole of the wheel hub is aligned with the annular positioning groove 311 of the support base 31 and inserted. The inner wall of the center hole of the wheel hub presses against the guide slope of the pin 333, causing the pin 333 to compress the spring 332 and retract into the sleeve 331. After the wheel hub is fully inserted into the annular positioning groove 311, the spring 332 returns to its original position and pushes the pin 333 out. The end of the pin 333 is engaged in the appropriate position of the center hole of the wheel hub, realizing the axial rapid positioning of the wheel hub.

[0027] In practical implementation of this utility model: Before use, check the connection status of each component to ensure that the sliding limit block 22 slides smoothly in the T-shaped guide rail 21 and that the electric lifting rod 32 extends and retracts normally. Place the wheel hub to be tested on the top surface of the main body 1 of the operating table, aligning the center of the wheel hub with the support seat 31. According to the diameter of the wheel hub, slide the sliding limit block 22 along the T-shaped guide rail 21. After adjusting the position with reference to the scale 24, rotate the operating handle 231 to lock the sliding limit block 22. The arc-shaped contact surface 221 fits against the outer peripheral wall of the wheel hub, completing the radial limit. Start the electric lifting rod 32 to drive the support seat 31 to rise. The center hole of the wheel hub fits into the annular positioning groove 311, and the pin 333 of the elastic positioning pin 33 automatically pops out and clamps the wheel hub, completing the axial limit. After the double limit is completed, the pressure resistance testing equipment can be started to test the wheel hub. After the test is completed, control the electric lifting rod 32 to descend, rotate the operating handle 231 in the opposite direction to release the sliding limit block 22, and remove the wheel hub.

[0028] During maintenance, check the wear of the cam on the cam-type quick-locking component 23, the elasticity of the spring 332 of the elastic locating pin 33, and the wear of the elastic wear-resistant layer 222. If any component is damaged, the sliding limit block 22 or the elastic locating pin 33 can be directly replaced without disassembling the complex structure. The entire process is simple to operate, has high limiting efficiency, accurate positioning, and convenient maintenance, making it suitable for automotive wheel hub pressure resistance testing needs.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
