Description

Technical Field

[0001] This utility model relates to a testing device, and more particularly to a testing device for wheel hub machining. Background Technology

[0002] Wheel hubs are crucial automotive components. With the rapid development of the automotive industry, many different wheel hub structures have emerged. For example, some wheel hubs require hubcaps. These hubs need a hubcap installed on the outer center of the hub after installation. The hubcap isolates impurities, reduces wear, and prevents physical impacts, protecting the wheel hub and its core components. It also serves a decorative purpose. Another type of wheel hub with a hubcap has its design extended to the hubcap itself; that is, part of the design is located on the hubcap. Only when the hubcap is installed can the entire wheel hub display a continuous and complete design. The position of the mounting holes in the hubcap mounting slot in the center of this type of wheel hub must meet the machining and assembly requirements. Only when the hubcap is installed in the mounting slot can the design on the hubcap connect with the design on the wheel hub to form a complete design; otherwise, the design on the wheel hub cannot be connected to the design on the hubcap to form a complete design. When manufacturing this type of wheel, wheel manufacturers typically pre-assemble a wheel cover into the mounting slot to check if the positions of the mounting holes in the wheel cover mounting groove meet the assembly requirements. They then observe the alignment of the wheel cover's contour with the wheel's contour to determine if the mounting hole positions in the mounting groove are correct. However, because the wheel cover is made of non-metallic materials, repeated pre-assembly for testing can cause wear and affect its dimensional accuracy. Furthermore, since the outer surface of the wheel cover is relatively flat, tools are required to disassemble it after pre-assembly, which is not only inefficient but also easily damages the wheel cover. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the existing technology by providing a wheel hub machining inspection device that can quickly inspect wheel hubs instead of wheel hub covers, while ensuring the accuracy of the inspection.

[0004] The technical solution adopted by this utility model to achieve the above-mentioned objective is as follows: a wheel hub machining and inspection device, comprising a cylindrical main body, a cylindrical handle extending vertically upward connected to the middle of the upper surface of the main body, a central positioning post extending vertically downward connected to the center of the bottom surface of the main body and capable of being positioned inside the center hole of the wheel hub, and mounting hole positioning posts capable of being positioned in the mounting holes of the wheel hub connected to the bottom surface of the main body surrounding the central positioning post, the mounting hole positioning posts being arranged in a circular matrix on the bottom surface of the main body outside the central positioning post, and a plurality of outwardly protruding contour positioning protrusions connected to the outer circumferential wall surface of the main body.

[0005] A further technical solution of this utility model is: a central connecting hole is provided in the center of the main body, the central positioning post is a circular cylinder with a hollow bottom, the central positioning post is connected to the bottom of the main body by a connecting screw, the upper end of the connecting screw passes through the central connecting hole and connects to the internal threaded hole at the bottom of the cylindrical handle, and the outer diameter of the central positioning post is equal to the diameter of the center hole of the wheel hub.

[0006] A further technical solution of this utility model is: a peripheral connecting hole is provided on the outside of the central connecting hole of the main body. The peripheral connecting holes are arranged in a circular matrix on the outside of the central connecting hole. The positions of the peripheral connecting holes correspond one-to-one with the positions of the mounting holes of the wheel hub. The mounting hole positioning post is connected to the peripheral connecting hole on the bottom surface of the main body through a connecting device.

[0007] A further technical solution of this utility model is: the mounting hole positioning post includes an upper positioning post with a larger diameter and a lower positioning post with a smaller diameter. The upper positioning post cooperates with the upper countersunk hole of the wheel hub mounting hole, and the lower positioning post cooperates with the lower through hole of the wheel hub mounting hole.

[0008] A further technical solution of this utility model is: the adjacent contour positioning protrusions are spaced equally, and when the wheel hub machining and inspection device is set in the wheel hub cover mounting groove, the contour positioning protrusions extend to the side wall of the wheel hub cover mounting groove.

[0009] A further technical solution of this utility model is: the upper surface of the main body is also provided with a triangular positioning mark that corresponds to the position of the valve hole of the wheel hub.

[0010] A further technical solution of this utility model is: the main body part inside the contour positioning protrusion is provided with a weight reduction hole that penetrates the upper and lower surfaces of the main body part.

[0011] This utility model discloses a wheel hub machining inspection device with the following advantages: The device is made of metal and features a cylindrical handle at the top and a central positioning post and mounting hole positioning post at the bottom. A contour positioning protrusion is provided on the outer circumference of the device. The cylindrical handle allows the inspector to easily grip the device and move it in and out of the wheel hub cover mounting slot without the need for specialized tools, making inspection convenient and quick. The central positioning post and mounting hole positioning post quickly position the device in the wheel hub cover mounting slot, and the contour positioning protrusion quickly aligns with the contour shape reference. As long as the central positioning post is positioned in the center hole of the wheel hub, all mounting hole positioning posts are positioned in the wheel hub mounting holes, and all contour positioning protrusions are aligned with the wheel hub contour shape reference, it can be determined that the wheel hub machining meets the wheel hub cover assembly requirements. The inspection device is not easily deformed or worn, can quickly inspect wheel hubs instead of wheel hub covers, and ensures the accuracy of the inspection.

Detailed Implementation

[0019] like Figure 1 , Figure 2 As shown, this utility model discloses a wheel hub machining inspection device, used to inspect the machined wheel hub 12 (e.g., ...). Figure 3 As shown, to meet the assembly requirements of the hub cap, the design of the hub 12 is extended to the hub cap, and part of the design is located on the hub cap. The hub surface can only show the continuous design after the hub cap (not shown in the figure) is correctly installed. The hub has a hub center hole 9, and five mounting holes 8 are provided around the hub center hole 9. The recessed part outside the hub center hole 9 and the mounting holes 8 is used to assemble the hub cap, also known as the hub cap mounting groove 11. The hub cap is placed on the hub cap mounting groove 11.

[0020] like Figure 1 , Figure 2As shown, this utility model discloses a wheel hub machining inspection device, comprising a cylindrical main body 1. A cylindrical handle 2 extending vertically upwards is connected to the center of the upper surface of the main body 1. The surface of the cylindrical handle 2 is provided with anti-slip stripes, and the cylindrical handle 2 facilitates the inspector's grip to place or remove the inspection device into or out of the wheel hub cover mounting groove 11. A central positioning post 7 extending vertically downwards and positioned inside the wheel hub center hole 9 is connected to the center of the bottom surface of the main body 1. The center of the main body 1 is provided with a central connecting hole 15. The central positioning post 7 is a circular cylinder with a hollow bottom. The central positioning post 7 is connected to the bottom of the main body 1 by a connecting screw. The upper end of the connecting screw passes through the central connecting hole 15 and connects to the internal threaded hole at the bottom end of the cylindrical handle 2. The outer diameter of the central positioning post 7 is equal to the diameter of the wheel hub center hole 9.

[0021] like Figure 1 , Figure 2 As shown, a mounting hole positioning post 6, capable of being positioned in the wheel hub mounting hole 8, is also connected to the bottom surface of the main body 1 surrounding the central positioning post 7. The mounting hole positioning posts 6 are arranged in a circular matrix on the bottom surface of the main body 1 outside the central positioning post 7. A peripheral connecting hole 14 is provided outside the central connecting hole 15 of the main body 1. The peripheral connecting holes 14 are arranged in a circular matrix outside the central connecting hole 15, and their positions correspond one-to-one with the positions of the wheel hub mounting holes 8. The mounting hole positioning posts 6 are connected to the peripheral connecting holes 14 on the bottom surface of the main body 1 via a connecting device. The mounting hole positioning post 6 includes an upper positioning post with a larger diameter and a lower positioning post with a smaller diameter. The upper positioning post mates with the countersunk hole at the upper end of the wheel hub mounting hole 8, and the lower positioning post mates with the through hole at the lower end of the wheel hub mounting hole 8. (See also...) Figure 5 As shown.

[0022] like Figure 1 , Figure 2 As shown, multiple outwardly protruding contour positioning protrusions 4 are connected to the outer circumferential wall surface of the main body 1. Adjacent contour positioning protrusions 4 are equally spaced. When the wheel hub machining inspection device is installed in the wheel hub cover mounting groove 11, the contour positioning protrusions 4 extend beyond the side wall of the wheel hub cover mounting groove 11. The spacing of the contour positioning protrusions 4 is determined according to the wheel hub's design. In this embodiment, the contour positioning protrusions 4 correspond to the positions of one side rib 13 of the wheel hub blade design. Of course, as a variation of this invention, the position and spacing of the contour positioning protrusions 4 can be changed according to the wheel hub's design, as long as the reference positioning function can be achieved. A triangular positioning mark 5, corresponding to the position of the valve hole 10 of the wheel hub, is also provided on the upper surface of the main body 1. The triangular positioning mark 5 is used for relative positioning with respect to the position of the valve hole 10 of the wheel hub. A weight-reducing hole 3 penetrating the upper and lower surfaces of the main body 1 is provided on the inner side of the contour positioning protrusions 4. This through hole effectively reduces the overall weight of the inspection device.

[0023] When working, see Figure 4 , 5 As shown, the wheel hub to be inspected is placed on the workbench (not shown in the figure), and the inspection device is placed in the wheel hub cover mounting groove 11. The center positioning post 7 is located in the center hole 9 of the wheel hub, the triangular positioning mark 5 is directly opposite the position of the valve hole 10 of the wheel hub, and all five mounting hole positioning posts 6 are positioned in the wheel hub mounting holes 8. Observe whether the contour positioning protrusion 4 corresponds to the position of the rib 13 on one side of the wheel hub blade shape. If they correspond, it is qualified, that is, it meets the assembly requirements. If they do not correspond, it is unqualified. In the figure, 4 shows the contour positioning protrusion 4 corresponding to the rib 13 on one side of the wheel hub blade shape.
