Description

Technical Field

[0001] This invention relates to the field of wheel hub testing technology, specifically to a drive-integrated wheel hub strength testing device. Background Technology

[0002] In modern society, with the development of industrial civilization, cities are becoming larger and larger, and cars have become an essential means of transportation for many families. Especially for people who travel frequently for work, cars are also an important tool. Moreover, the strength testing of car wheel hubs is crucial. Wheel hub strength testing is an important test to evaluate the performance and safety of wheel hubs under stress, such as tensile performance testing, impact toughness testing, fatigue strength testing, and hardness testing.

[0003] However, most existing wheel hub strength testing devices cannot detect wheel hub strength under simulated impact conditions, resulting in unknown wheel hub strength during actual use. Some testing devices that can perform similar simulations do not have protective structures, so fragments ejected under simulated impact conditions may accidentally injure users. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: An integrated wheel hub strength testing device includes a base plate with fixing holes at the four corners of its top end. A support mechanism is provided at the top end of the base plate, and the support mechanism includes a base. The base is fixedly installed at the top end of the base plate, and a pressing mechanism is provided at the four corners of the top end of the base. A pad is fixedly installed in the middle of the top end of the base, and a fixing screw is fixedly installed on the pad. A locking groove is provided in the middle of the top end of the pad, and an obstruction block is fixedly installed at the bottom end of the locking groove. A pressure block is fixedly installed inside the pad.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figures 1-4 As shown, the present invention provides a technical solution: An integrated wheel hub strength testing device includes a base plate 101. Fixing holes 102 are provided at the four corners of the top of the base plate 101. A support mechanism 103 is provided at the top of the base plate 101. The support mechanism 103 includes a base 104, which is fixedly installed at the top of the base plate 101. A pressing mechanism 105 is provided at the four corners of the top of the base 104. A pad 106 is fixedly installed in the middle of the top of the base 104. A fixing screw 201 is fixedly installed on the pad 106. A locking groove 202 is provided in the middle of the top of the pad 106. An obstruction block 203 is fixedly installed at the bottom of the locking groove 202. A pressure block 204 is fixedly installed inside the pad 106.

[0017] The above solution allows the base plate to be fixed through the fixing holes, thereby enabling the base to be installed. The fixing screws can be used to fix the pads. The pressure block can monitor the pressure level. The locking groove can lock the wheel hub to prevent movement. The obstacle block can simulate the wheel hub hitting an obstacle.

[0018] In this embodiment, preferably, the pressing mechanism 105 includes a support rod 205, which is fixedly installed at the four corners of the top of the base 104. A drive box 206 is fixedly installed at the top of the support rod 205, and a protective net cover 301 is fixedly installed between the drive box 206 and the base 104.

[0019] With the above solution, the drive box can be supported on the top of the base by the support rod, and the device can be protected by the protective net to prevent fragments from breaking out during testing.

[0020] In this embodiment, preferably, the protective net cover 301 is fixedly installed with assembly screws 302 on the upper and lower sides, the protective net cover 301 is movably installed with a protective net door 303 at the front end, and the protective net door 303 and the opening and closing part of the protective net cover 301 are fixedly installed with hinges 304.

[0021] The above solution allows the protective mesh cover to be fixed with assembly screws, the wheel hub to be easily placed and removed by the mesh door latch, and the mesh door to be opened and closed by hinges.

[0022] In this embodiment, preferably, a heat dissipation window 305 is provided at the left end of the drive box 206, a control button 306 is fixedly installed on the left front end of the drive box 206, and a display screen 401 is fixedly installed on the right front end of the drive box 206.

[0023] The above solution allows the drive box to dissipate heat through the heat dissipation window, the device can be controlled by the control button, and pressure data can be displayed on the display screen.

[0024] In this embodiment, preferably, a cover 402 is fixedly installed on the top of the drive box 206, a connecting screw 403 is fixedly installed on the top of the cover 402, a hydraulic cylinder 404 is fixedly installed inside the drive box 206, and a hydraulic rod 405 is fixedly installed at the bottom of the hydraulic cylinder 404.

[0025] The above solution allows for easy disassembly and assembly of the cover using connecting screws, which in turn facilitates internal maintenance and repair of the drive box. The hydraulic cylinder can also be used to raise and lower the hydraulic rod.

[0026] In this embodiment, preferably, the bottom end of the hydraulic rod 405 passes through the drive box 206 and is fixedly installed with a pressure plate 406, the top end of the pressure plate 406 is fixedly installed with an installation screw 501, and the bottom end of the pressure plate 406 is fixedly installed with a lower pressure block 502.

[0027] The above solution allows the lower pressure block to be fixed to the pressure plate by installing screws through it, and the lower pressure block can then be used to fix the top of the wheel hub.

[0028] In this embodiment, the integrated wheel hub strength testing device is used by the user to fix the base plate 101 to the ground through the fixing hole 102, then fix the pad 106 to the top of the base 104 through the fixing screw 201, and connect the pressure block 204 to the display screen 401 through the connecting cable. The pressure block 204 adopts the method described in (Publication No. 201710076012.6). The pressure sensor's structure allows for real-time pressure monitoring, while the built-in ADC (Analog-to-Digital Converter) chip in the display screen 401 converts the pressure change signal in the pressure block 204 into a numerical display. The user then uses mounting screws 501 to connect the pressure plate 406 to the lower pressure block 502, securing the lower pressure block 502. After securing, the user uses assembly screws 302 to fix the protective mesh cover 301 between the drive box 206 and the base 104, causing the protective mesh door 303 to be driven and assembled. After assembly, the user places the wheel hub with the tires into the engaging slot 202 at the top of the pad 106 and closes the protective mesh door 303. At this point, the entire system is powered on. Once powered on, the user can control the device via button 306. The hydraulic cylinder 404 is controlled to work, which drives the hydraulic rod 405 to press down, causing the pressure plate 406 to drive the lower pressure block 502 to press down on the top of the wheel hub. The bottom end of the lower pressure block 502 has a groove with the same shape as the locking groove 202. When pressing down, the wheel hub is locked and kept stable. At the same time, the wheel hub is subjected to force by continuing to press down. When subjected to force, it is hindered by the obstacle block 203. Therefore, if the pressure is too high, the wheel hub will be damaged. At the moment of wheel hub damage, the pressure is buffered instantly. Therefore, the pressure monitored by the pressure block 204 will fluctuate. The pressure peak before the fluctuation is the maximum compressive strength of the wheel hub. When the wheel hub is crushed, the fragments generated will be blocked by the protective net cover 301 and the protective net door 303, thereby preventing the user from being accidentally injured.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
