[0002] The wheel hub is a cylindrical metal component whose center is mounted on an axle, supporting the tire's inner profile. During the initial pouring and riser process in wheel hub machining, eccentricity can occur when drilling the hub's center hole. This problem not only seriously affects the accuracy of the drilled hole diameter, resulting in the hole size not meeting design requirements, thus affecting the overall performance and service life of the wheel hub, but also adversely affects the surface quality of the drilled hole, such as scratches and burrs, which reduce the wheel hub's aesthetics and safety. More seriously, eccentricity can lead to uneven clearance between the tool and the workpiece during subsequent machining and turning, increasing the risk of tool collision. This not only damages expensive tools and affects machining efficiency, but can also cause the wheel hub to be scrapped, resulting in significant economic losses for the company.

[0003] Traditional detection methods often rely on manual measurement, which is not only inefficient but also difficult to ensure accuracy. Therefore, it is of great significance to develop an automated, high-precision wheel hub center hole position detection device. Utility Model Content

[0030] like Figure 1-4 As shown, a device for detecting the size of the center hole of a wheel hub includes a support platform, a moving assembly, a detection tool and a fixed assembly 4. The moving assembly is vertically connected to the support platform, and the detection tool is fixed by the fixed assembly 4. The moving assembly includes a slide rail bracket 21, a slide rail 22, a slider 23 and a cylinder 24, and the fixed assembly 4 includes a first fixing member 41 and a second fixing member 42. The slide rail bracket 21 is vertically fixed to the support platform, the cylinder 24 is installed on the first side of the slide rail bracket 21, the slide rail 22 is installed on the second side of the slide rail bracket 21, and the slider 23 is embedded in the slide rail 22. The first fixing member 41 connects the detection tool with the slider 23, and the second fixing member 42 connects the first fixing member 41 and the telescopic rod of the cylinder 24.

[0031] When inspecting the center hole position of the wheel hub, the support platform is placed on the wheel hub 5. The wheel hub 5 rotates on the workstation, and the moving assembly, powered by cylinder 24, drives the inspection tool up and down. The inspection tool moves up and down along the diameter edge of the center hole 51 of the wheel hub 5. If the center hole 51 is undersized or has a roundness deviation, the inspection tool's downward movement is blocked, indicating that the center hole 51 of the wheel hub 5 is unqualified. The device for inspecting the size of the wheel hub center hole provided by the utility model can automatically and accurately inspect the size and roundness of the center hole 51 of the wheel hub 5, improving inspection efficiency and accuracy while reducing the difficulty and error of manual operation.

[0032] In one embodiment, Figure 1 and 2 As shown, the detection tool is a probe 31. The probe 31 can be accurately inserted into the diameter edge of the center hole 51 of the hub 5 to determine whether the position of the center hole 51 is correct. If it is blocked, it means that the center hole 51 is too small or offset.

[0033] Furthermore, if Figure 3 and 4As shown, the first fixing member 41 includes a U-shaped portion 411 and a plurality of snap portions 412. The two side surfaces of the U-shaped portion 411 wrap around the slider 23, the slide rail 22 and the slide rail bracket 21. One side of the closed surface of the U-shaped portion 411 is connected to the slider 23, and the other side of the closed surface of the U-shaped portion 411 is provided with a snap portion 412. The probe 31 is fixed by the snap portion 412. Specifically, the slider 23 is provided with a plurality of mounting holes, and the closed surface of the U-shaped portion 411 is provided with a plurality of mounting holes. The closed surface of the U-shaped portion 411 is attached to the slider 23, and the fasteners are passed through the mounting holes to fix it. The closed surface of the U-shaped portion 411 is provided with two openings, and the openings are provided with mounting holes. The probe 31 is fixed by fasteners passing through the mounting holes, which not only ensures the stability of the probe 31 but also facilitates the replacement of the probe 31.

[0034] The second fixing member 42 is located on the first side of the slide rail bracket 21 and connected to both sides of the U-shaped portion 411. The telescopic rod of the cylinder 24 is connected to the second fixing member 42. The connection between the first fixing member 41 and the second fixing member 42 transmits power to the slider 23, driving the slider 23 to slide on the slide rail 22. The rolling contact between the slide rail 22 and the slider 23 helps reduce vibration and impact during movement, thereby improving the stability and reliability of the device.

[0035] The first fixing member 41 and the second fixing member 42 are welded or integrally formed. The first fixing member 41 can be installed separately and then welded together to improve the stability and durability of the structure, or it can be integrally formed and inserted into the moving assembly and then connected to the slider 23 and the telescopic rod of the cylinder 24 respectively through fasteners.

[0036] In another embodiment, the detection tool is an infrared device. The infrared device emits infrared light and receives reflected signals to determine whether the size of the center hole 51 is acceptable. The infrared device can detect the position of the hub center hole non-contact, avoiding potential damage to the probe 31 and improving detection efficiency.

[0037] In other embodiments, there are two sliders 23, and the first fixing member 41 connects the detection tool to the two sliders 23. Figure 3 and 4 As shown, two sliders 23 are connected to the front of the U-shaped portion 411 . The arrangement of the two sliders 23 makes the detection tool more stable when moving up and down, reduces shaking and errors, and increases the service life of the sliders 23 .

[0038] In other embodiments, the support platform includes an I-shaped support 11 and a counterweight 12, and the counterweight 12 is located on the second side of the slide rail 22. The counterweight 12 is used to balance the center of gravity of the entire device and improve the stability of the device.

[0039] It should also be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device.
