Description

Technical Field

[0001] This utility model relates to the field of wheel hub manufacturing and testing technology, and in particular to a tooling for detecting deformation of forged wheel hub spokes. Background Technology

[0002] Forged passenger vehicle wheels, due to their high strength and lightweight characteristics, have become one of the core components for automotive lightweighting upgrades. However, during the die forging and heat treatment processes, geometric deformation of the wheel spokes (such as radial warping and circumferential twisting) caused by factors such as uneven material flow and residual stress release has become a key process defect restricting the improvement of product qualification rate.

[0003] Currently, the industry mainly relies on two methods for detecting deformation of forged wheel spokes: manual inspection and inspection using general measuring equipment. Both methods have significant drawbacks. The manual experience-based method involves operators using simple measuring tools such as calipers and rulers to randomly check key dimensions of the spokes based on experience. The accuracy of this method is greatly affected by subjective factors, and it can only identify macroscopic deformations, resulting in insufficient precision. The general measuring equipment method uses coordinate measuring machines or laser scanners for full-dimensional inspection. While this method offers higher accuracy, the inspection time for a single piece is as long as 20-30 minutes, which cannot meet production line cycle time. Furthermore, it suffers from difficulties in locating complex curved surfaces, and there are blind spots in areas such as the back of the spokes and the periphery of heat dissipation holes.

[0004] Therefore, developing a tooling for detecting deformation of forged wheel hub spokes and applying it to actual production is an urgent problem to be solved. Utility Model Content

[0005] The purpose of this invention is to provide a tooling for detecting deformation of forged wheel hub spokes, thereby solving the aforementioned problems in the current process of detecting deformation of forged wheel hub spokes.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A forged wheel hub spoke deformation detection fixture includes a horizontally arranged detection platform for supporting the wheel hub to be inspected. Several detection components are arranged on the detection platform for detecting wheel hub deformation. The detection components circumferentially enclose a space for holding the wheel hub. Each detection component includes a support arm fixedly connected to the detection platform. Detection probes are arranged on the support arm corresponding to different detection points on the spoke portion of the wheel hub to be inspected. The probes are movably inserted into the support arm. A scale is marked on the detection probes, with the zero mark of the scale corresponding to the position of a standard wheel hub spoke detection point, used to indicate the dimensional deviation of the detection point.

[0008] Preferably, the support arm includes a column fixedly connected to the detection platform and a horizontal arm hinged to the column, so that the horizontal arm can be rotated upward with the hinge point as the axis.

[0009] Preferably, the detection platform is provided with a positioning structure for positioning the wheel hub to be detected. The positioning structure includes a positioning mandrel corresponding to the center hole of the wheel hub. The positioning mandrel is inserted into the shaft hole of the center hole of the wheel hub for center positioning of the wheel hub to be detected.

[0010] Preferably, the positioning structure includes a positioning post corresponding to the bolt hole of the wheel hub to be tested. The positioning post is inserted into the bolt hole shaft hole for radial angle positioning of the wheel hub to be tested.

[0011] Preferably, the positioning structure includes a positioning seat disposed on the detection platform, the positioning seat being circumferentially spaced corresponding to the lower wheel lip of the wheel hub to be detected, for axial positioning of the wheel hub to be detected.

[0012] Preferably, the detection probe is provided with a limiting pin, which is located on the inner and outer sides of the support arm to limit the free travel of the detection probe.

[0013] Preferably, the bottom of the testing platform is connected to a frame, which supports the testing platform at a height suitable for the testing personnel to operate, facilitating the testing operation.

[0014] Preferably, the testing platform is equipped with lifting rings to facilitate the lifting and transportation of the testing platform.

[0015] The beneficial effects of this invention are as follows: This invention simplifies the detection method of the spoke spatial curved surface of forged wheel hubs to point-to-point detection. By using multiple detection probes to detect the deformation at multiple detection points on the wheel hub spokes, the deformation at that local location can be obtained. This invention overcomes the problems of traditional manual inspection, where the detection results are greatly affected by subjective factors and the detection accuracy is insufficient, effectively improving the detection accuracy. At the same time, it eliminates the cumbersome operation of using a coordinate measuring machine or laser scanner for full-size inspection, improving detection efficiency and reducing blind spots.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figure 1-3 As shown, a forged wheel hub spoke deformation detection fixture includes a horizontally arranged detection platform 10 for supporting the wheel hub to be inspected. Several detection components are arranged on the detection platform 10 for detecting wheel hub deformation. The several detection components circumferentially enclose a space for placing the wheel hub to be inspected. Each detection component includes a support arm 11 fixedly connected to the detection platform 10. Detection probes 12 are arranged on the support arm 11 corresponding to different detection points on the spoke portion of the wheel hub to be inspected. The probes are movably inserted into the support arm 11. A scale 121 is marked on the detection probes 12. The zero mark of the scale 121 corresponds to the position of the standard wheel hub spoke detection point, used to indicate the dimensional deviation of the detection point.

[0023] In use, the wheel hub to be inspected is placed within the receiving space formed by the inspection components. The inspection probe 12, which is movably inserted into the support arm 11, slides down under its own weight and abuts against the spoke surface of the wheel hub. At this time, the deformation at the inspection point can be measured by observing the scale 121 on the inspection probe 12. This embodiment simplifies the inspection method of the spoke spatial curved surface to point inspection. By using multiple inspection probes 12 to detect the deformation at multiple inspection points of the wheel hub spokes, the deformation at that local location can be obtained. This embodiment overcomes the problems of traditional manual inspection, where the inspection results are greatly affected by subjective factors and the inspection accuracy is insufficient, effectively improving the inspection accuracy. At the same time, it eliminates the cumbersome operation of using a coordinate measuring machine or laser scanner for full-size inspection, improving inspection efficiency and reducing inspection blind spots.

[0024] Preferably, such as Figure 2 As shown, the support arm 11 includes a column 111 fixedly connected to the detection platform 10 and a horizontal arm 112 hinged to the column 111, so that the horizontal arm 112 can be rotated upward with the hinge point as the axis, thereby opening the accommodating space for placing the wheel hub to be detected, making it easy to put the wheel hub to be detected into the accommodating space. The detection probe 12 is movably inserted into the horizontal arm 112.

[0025] Preferably, such as Figure 1 As shown, the detection platform 10 is equipped with a positioning structure for positioning the wheel hub to be inspected, thereby ensuring detection accuracy. The positioning structure includes a positioning mandrel 21 corresponding to the center hole of the wheel hub. The positioning mandrel 21 is inserted into the shaft hole of the center hole of the wheel hub for center positioning of the wheel hub to be inspected.

[0026] Preferably, the positioning structure includes a positioning post 22 corresponding to the bolt hole of the wheel hub to be tested. The positioning post 22 is inserted into the bolt hole shaft hole for radial angle positioning of the wheel hub to be tested, so as to ensure the correspondence between the detection component and the wheel spoke detection point.

[0027] Preferably, the positioning structure includes a positioning seat 23 disposed on the detection platform 10. The positioning seat 23 is circumferentially spaced corresponding to the lower wheel lip of the wheel hub to be detected, and is used for axial positioning of the wheel hub to be detected.

[0028] During testing, the positioning mandrel 21 is inserted into the center hole of the hub to be tested, and the positioning pin 22 is inserted into the bolt hole of the hub to be tested, completing the center positioning and radial angle positioning; at the same time, the lower rim of the hub to be tested abuts against the positioning seat 23, completing the axial positioning. The circumferentially spaced positioning seats 23 ensure that the lower rim of the hub to be tested contacts the positioning seats 23 at only a few discrete points, eliminating positioning interference caused by slight deformation of the rim or flatness error of the testing platform 10, and improving the axial positioning accuracy.

[0029] Preferably, the detection probe 12 is provided with a limiting pin 122, which is located on the inner and outer sides of the support arm 11 to limit the free travel of the detection probe 12 and prevent the detection probe 12 from falling off accidentally.

[0030] Preferably, the bottom of the testing platform 10 is connected to a frame 30, which supports the testing platform 10 at a height suitable for the testing personnel to operate, thus facilitating the testing operation.

[0031] Preferably, the testing platform 10 is provided with a lifting ring 13 for lifting the testing platform 10, which facilitates the relocation of the testing platform 10.

[0032] The above-disclosed embodiments are merely specific examples of this utility model, but this utility model is not limited thereto. For those skilled in the art, any modifications made without departing from the principle of this utility model should be considered as protected by this utility model.
