Description

Technical Field

[0001] This utility model relates to the field of vehicle component testing technology, and specifically to a vehicle half-shaft testing device. Background Technology

[0002] As a core component of the automotive transmission system, the health of the half-shaft directly affects the vehicle's power, economy, and safety. Due to its long-term operation under harsh conditions of high torque, alternating loads, and impacts from complex road conditions, wear, cracks, and deformation are inevitable. If these defects are not detected in time, they can lead to minor issues such as abnormal noises and vibrations, affecting the driving experience; in severe cases, they may break suddenly while driving, causing loss of vehicle control and serious traffic accidents. Therefore, rapid, accurate, and non-destructive testing of the half-shaft is crucial before manufacturing and during maintenance. Currently, the inspection of automotive half-shafts mostly relies on visual observation by workers or measurement using simple tools such as calipers and dial indicators. This method is not only inefficient and susceptible to subjective factors, but also fails to detect minute cracks and deformations, failing to meet the high standards of quality and safety required by modern industry.

[0003] Therefore, to address the aforementioned pain points, a new type of automotive half-shaft testing device is needed to achieve efficient and accurate testing, thereby meeting the high standards of quality and safety requirements of modern industry. Utility Model Content

[0004] One of the objectives of this invention is to provide a vehicle half-shaft detection device to solve the problems of insufficient efficiency and accuracy in existing vehicle half-shaft detection methods.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A vehicle half-shaft inspection device includes an inspection platform with a support surface formed thereon for supporting the half-shaft of the vehicle under test; it also includes a 3D scanner and an industrial camera, the 3D scanner and the industrial camera being mounted on the inspection platform, the 3D scanner being configured to reconstruct a three-dimensional model of the half-shaft of the vehicle under test, and the industrial camera being configured to work in conjunction with the 3D scanner to identify surface defects of the half-shaft of the vehicle under test; the support surface is inclined; and friction strips are laid on the support surface.

[0007] Based on the aforementioned technical means, the inclined support surface allows the half-shaft of the vehicle under test to roll under its own weight. The friction strip provides resistance to the rolling of the half-shaft on the support surface, enabling it to roll at a low speed and smoothly. This allows the 3D scanner to accurately and clearly scan and reconstruct the three-dimensional model of the half-shaft, thereby quantifying its deformation and wear. Simultaneously, it facilitates the industrial camera to clearly photograph the half-shaft to capture its surface micro-defects. The collaborative work of the 3D scanner and the industrial camera enables rapid, comprehensive, accurate, and non-destructive testing of defects in the half-shaft, improving the testing efficiency and accuracy of the half-shaft.

[0008] Furthermore, it also includes a first lifting column and a second lifting column; the 3D scanner is mounted on the detection platform via the first lifting column to realize the lifting movement of the 3D scanner; the industrial camera is mounted on the detection platform via the second lifting column to realize the lifting movement of the industrial camera.

[0009] Based on the above-mentioned technical means, the first and second lifting columns can respectively realize the height adjustment of the 3D scanner and the industrial camera to adapt to the detection of half shafts of vehicles of different specifications, thereby improving the adaptability and practicality of the 3D scanner and the industrial camera in detecting half shafts of vehicles.

[0010] Furthermore, it also includes a first spherical gimbal and a second spherical gimbal; the 3D scanner is mounted on the first lifting column via the first spherical gimbal to achieve the rotational movement of the 3D scanner; the industrial camera is mounted on the second lifting column via the second spherical gimbal to achieve the rotational movement of the industrial camera.

[0011] Based on the aforementioned technical means, the 3D scanner can quickly adjust its spatial posture through the first spherical gimbal, realizing flexible and rapid angle adjustment of the 3D scanner from multiple angles, making it easy to quickly align the 3D scanner with the scanning station; similarly, the industrial camera can achieve flexible and rapid angle adjustment from multiple angles through the second spherical gimbal, making it easy to align with the scanning station, thus improving the efficiency of posture adjustment of the 3D scanner and the industrial camera.

[0012] Furthermore, buffer blocks are provided at both ends of the support surface.

[0013] Based on the above technical means, the buffer block is used to flexibly block and limit the rolling of the half shaft of the vehicle under test, so as to effectively absorb the impact energy of the half shaft of the vehicle under test on the testing platform and prevent the half shaft of the vehicle under test from being damaged or broken due to collision.

[0014] Furthermore, a lifting baffle is provided on the support surface, the lifting baffle is located between the two buffer blocks, and the lifting baffle is arranged parallel to the two buffer blocks.

[0015] Based on the above technical means, the lifting baffle positions the half shaft of the vehicle under test before the test. When the test begins, the lifting baffle descends, so that the half shaft of the vehicle under test starts to roll only under its own weight, avoiding positional deviation caused by human rolling and improving the accuracy of the test.

[0016] Furthermore, it also includes a display panel, an operation panel, and a processor, which are located on the detection platform. The 3D scanner, industrial camera, display panel, and operation panel are all communicatively connected to the processor. The display panel is configured to display the detection results, and the operation panel is configured to operate the vehicle half-shaft detection device.

[0017] Based on the aforementioned technical means, the processor is the control center of the entire vehicle half-shaft inspection device, enabling communication / control connections between the display panel, operation panel, 3D scanner, and industrial camera; the operation panel serves as a human-machine interaction channel, allowing staff to conveniently operate the vehicle half-shaft inspection device, while the display panel visualizes the inspection results, facilitating staff viewing and improving the convenience of inspection.

[0018] Furthermore, it also includes a data interface connected to the processor, the data interface being used for data exchange.

[0019] Based on the above technical means, the vehicle half-shaft detection device of this solution can be connected to external devices through a data interface to realize data export and import, thereby improving the convenience of data processing.

[0020] Furthermore, the bottom of the testing platform is equipped with rollers, and the side of the testing platform is equipped with a handle.

[0021] Based on the above technical means, the rollers reduce friction when the testing platform moves, and the handles provide a point of leverage for the staff. The combination of the two enables the staff to move the testing platform conveniently.

[0022] The beneficial effects of this utility model are as follows:

[0023] The inclined support surface allows the half-shaft of the vehicle under test to roll under its own weight. The friction strip provides resistance to the rolling of the half-shaft on the support surface, enabling it to roll slowly and smoothly. This allows the 3D scanner to accurately and clearly scan and reconstruct the three-dimensional model of the half-shaft, quantifying its deformation and wear. Simultaneously, it facilitates clear imaging of the half-shaft by an industrial camera to capture its surface micro-defects. The collaborative work of the 3D scanner and industrial camera enables rapid, comprehensive, accurate, and non-destructive testing of defects in the half-shaft, improving the testing efficiency and accuracy.

[0032] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. The drawings are for illustrative purposes only and should not be construed as limiting the utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0033] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0034] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0035] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0036] This embodiment provides, as follows: Figures 1 to 5 The vehicle half-shaft inspection device shown includes an inspection platform 1 with a support surface 11 formed on it for supporting the vehicle half-shaft 01 under test; it also includes a 3D scanner 2 and an industrial camera 3, which are mounted on the inspection platform 1. The 3D scanner 2 is configured to reconstruct a three-dimensional model of the vehicle half-shaft 01 under test, and the industrial camera 3 is configured to work in conjunction with the 3D scanner 2 to identify surface defects of the vehicle half-shaft 01 under test; the support surface 11 is inclined; and friction strips 12 are laid on the support surface 11.

[0037] When using the vehicle half-shaft detection device in this embodiment to detect the vehicle half-shaft, the vehicle half-shaft 01 to be tested is placed on the support surface 11, and then the 3D scanner 2 and the industrial camera 3 are started to scan and photograph the vehicle half-shaft 01 to be tested, so that the 3D scanner 2 and the industrial camera 3 cooperate to identify the surface defects of the vehicle half-shaft 01 to be tested.

[0038] The inclined support surface allows the half-shaft of the vehicle under test to roll under its own weight. The friction strip 12 provides resistance for the rolling of the half-shaft 01 on the support surface 11, enabling the half-shaft 01 to roll slowly and smoothly on the support surface 11. This allows the 3D scanner 2 to accurately and clearly scan and reconstruct the three-dimensional model of the half-shaft 01, thereby quantifying the deformation and wear of the half-shaft 01. At the same time, it facilitates the industrial camera 3 to clearly photograph the half-shaft 01 to capture its surface micro-defects. The collaborative work of the 3D scanner 2 and the industrial camera 3 enables rapid, comprehensive, accurate, and non-destructive testing of defects in the half-shaft 01, improving the testing efficiency and accuracy of the half-shaft 01.

[0039] like Figure 2 and Figure 3 As shown, the inclined support surface 11 allows the half-shaft 01 of the vehicle under test to roll under its own weight, enabling the 3D scanner 2 and industrial camera 3 to comprehensively detect surface defects on the half-shaft 01. Specifically, the inclination angle of the support surface 11 along the rolling direction of the half-shaft 01 gradually decreases, causing the acceleration of the half-shaft 01 to gradually decrease during rolling along the support surface 11, preventing excessive acceleration of the half-shaft 01 that could lead to inaccuracies when the 3D scanner 2 and industrial camera 3 scan or photograph it.

[0040] like Figure 2 and Figure 3 As shown, the friction strips 12 provide frictional resistance for the rolling of the tested vehicle half-shaft 01 on the support surface 11, ensuring that the tested vehicle half-shaft 01 rolls at a low speed and smoothly during the rolling process. This guarantees that the 3D scanner 2 and the industrial camera 3 can fully scan or photograph the tested vehicle half-shaft 01. Specifically, multiple evenly spaced friction strips 12 are laid on the support surface 11. These evenly spaced friction strips 12 can generate continuous frictional resistance for the rolling of the tested vehicle half-shaft 01, preventing the tested vehicle half-shaft 01 from rolling too fast.

[0041] like Figures 1 to 3As shown, this embodiment also includes a first lifting column 4 and a second lifting column 5; the 3D scanner 2 is mounted on the detection platform 1 via the first lifting column 4 to achieve the lifting movement of the 3D scanner 2; the industrial camera 3 is mounted on the detection platform 1 via the second lifting column 5 to achieve the lifting movement of the industrial camera 3. The first lifting column 4 and the second lifting column 5 can respectively realize the height adjustment of the 3D scanner 2 and the industrial camera 3 to adapt to the detection of vehicle half-shafts 01 of different specifications, thereby improving the adaptability and practicality of the 3D scanner 2 and the industrial camera 3 in detecting vehicle half-shafts 01.

[0042] like Figure 2 and Figure 5 As shown, this embodiment also includes a first gimbal 6 and a second gimbal 7. The 3D scanner 2 is mounted on the first lifting column 4 via the first gimbal 6 to achieve rotational movement of the 3D scanner 2. The industrial camera 3 is mounted on the second lifting column 5 via the second gimbal 7 to achieve rotational movement of the industrial camera 3. The 3D scanner 2 can quickly adjust its spatial posture via the first gimbal 6, achieving flexible and rapid angle adjustment of the 3D scanner 2 from multiple angles, facilitating quick alignment of the 3D scanner 2 with the scanning station. Similarly, the industrial camera 3 can achieve flexible and rapid angle adjustment from multiple angles via the second gimbal 7, facilitating easy alignment with the scanning station and improving the efficiency of posture adjustment for both the 3D scanner 2 and the industrial camera 3.

[0043] The first ball head 6 and the second ball head 7 are electrically controlled ball heads. The first ball head 6 and the second ball head 7 have electromagnetic locking structures at the connection points with the first lifting column 4 and the second lifting column 5, respectively. After the attitude adjustment of the first ball head 6 and the second ball head 7 is completed, the two are locked to the first lifting column 4 and the second lifting column 5 respectively by the electromagnetic locking structures.

[0044] like Figure 2 and Figure 3 As shown, in this embodiment, buffer blocks 8 are provided at both ends of the support surface 11. The buffer blocks 8 are used to flexibly block and limit the rolling of the half-shaft 01 of the vehicle under test, so as to effectively absorb the impact energy of the half-shaft 01 of the vehicle under test on the detection platform 1 and prevent the half-shaft 01 of the vehicle under test from being damaged or broken due to collision. Specifically, the two buffer blocks 8 are vertically arranged and fit against the vertical surfaces at both ends of the support surface 11 (the dimensions of the two buffer blocks 8 are the same as those of the vertical surfaces at both ends of the support surface 11).

[0045] like Figure 2 and Figure 3As shown, in this embodiment, a lifting baffle 9 is provided on the support surface 11. The lifting baffle 9 is located between two buffer blocks 8 and is arranged parallel to the two buffer blocks 8. Before the test, the lifting baffle 9 positions the half-shaft 01 of the vehicle under test. At the start of the test, the lifting baffle 9 descends, causing the half-shaft 01 of the vehicle under test to begin rolling only under its own gravity, avoiding positional displacement caused by manual rolling and improving the accuracy of the test.

[0046] like Figure 1 and Figure 4 As shown, this embodiment also includes a display panel 10, an operation panel 13, and a processor (located within the detection platform 1, not shown in the figure). The display panel 10, operation panel 13, and processor are located on the detection platform 1. The 3D scanner 2, industrial camera 3, display panel 10, and operation panel 13 are all communicatively connected to the processor. The display panel 10 is configured to display the detection results, and the operation panel 13 is configured to operate the vehicle half-axle detection device. The processor is the control center of the entire vehicle half-axle detection device, enabling communication / control connections between the display panel 10, operation panel 13, 3D scanner 2, and industrial camera 3. The operation panel 13 serves as a human-machine interaction channel, allowing operators to conveniently operate the vehicle half-axle detection device, while the display panel 10 visualizes the detection results, facilitating viewing by operators and improving the convenience of the detection process.

[0047] Specifically, the control panel includes a power switch, a reset button, and a start button. These buttons are all connected to the processor. The power switch is used to electrically start and stop the entire vehicle half-shaft detection device. The reset button is used to reset the vehicle half-shaft detection device (returning it to its initial state before testing). In case of abnormal conditions such as unresponsive components, the reset button is used to safely and quickly restart the entire vehicle half-shaft detection device. The start button, after the entire vehicle half-shaft detection device is powered on, lowers the lifting baffle 9, causing the tested vehicle half-shaft 01 to lie flat along the support surface 11. The system is stable and allows the 3D scanner 2 and industrial camera 3 to adjust their spatial attitude and position via the first lifting column 4 and the second lifting column 5, the first ball head 6 and the second ball head 7, and to perform scanning and photography (during the scanning and photography process, the 3D scanner 2 and industrial camera 3 can transmit the collected scanning data and image data to the processor in real time for defect analysis, and display the 3D model, photo data, defect analysis and other information of the half shaft 01 of the tested vehicle reconstructed by the 3D scanner 2 through the display panel 10). After the inspection is completed, the processor can also generate an inspection report and display it through the display panel 10.

[0048] In this embodiment, the lifting baffle 9 is also configured to communicate with the processor mentioned above, and the operator can send instructions to the processor to make the lifting baffle 9 rise and fall (the lifting baffle 9 is an electrically controlled lifting plate); the first lifting column 4 and the second lifting column 5 are also communicated with the processor respectively, and the operator can send instructions to the processor to make the first lifting column 4 and the second lifting column 5 rise and fall (the first lifting column 4 and the second lifting column 5 are electrically controlled lifting columns).

[0049] like Figure 1 and Figure 4 As shown, this embodiment also includes a data interface 14, which is mounted on the detection platform 1 and connected to the processor. The data interface 14 is used for data exchange. The vehicle axle detection device of this solution can connect to external devices through the data interface 14 to achieve data export and import, improving the convenience of data processing. Specifically, the data interface 14 includes a USB interface, an Ethernet interface, and a power interface. The data interface 14 is used to connect to external storage devices, import 3D drawings, export detection data, or perform system maintenance; it also supports the connection of a mouse and keyboard for convenient human-computer interaction. The Ethernet interface is used to connect to a high-speed communication network, enabling the vehicle axle detection device of this embodiment to access the network and achieve the import of 3D drawings and the uploading of detection data. The power interface is used to connect to a power source to provide power to the vehicle axle detection device.

[0050] like Figure 2 As shown, in this embodiment, rollers 15 are installed at the bottom of the testing platform 1, and handles 16 are installed on the side of the testing platform 1. The rollers 15 reduce friction when the testing platform 1 moves, and the handles 16 provide a point of leverage for the operator. The two work together to enable the operator to move the testing platform 1 conveniently.

[0051] In this embodiment, the roller 15 is a liftable structure, specifically including a hydraulic lifting rod and a wheel body. A mounting groove is formed at the bottom of the detection platform 1. When retracted, the hydraulic lifting rod and wheel body can be fully retracted into the mounting groove, allowing the bottom of the detection platform 1 to be completely placed on the ground during the detection process. The friction with the ground ensures smooth operation of the detection platform 1. When it is necessary to move the detection platform 1, the hydraulic lifting rod is extended, allowing the wheel body to support the detection platform 1.

[0052] like Figure 4 As shown, in this embodiment, the detection platform 1 is also equipped with an indicator light 17 and a heat dissipation hole 18. The indicator light 17 is connected to the processor and has two states: when powered on, the indicator light 17 is green, indicating that the vehicle half-shaft detection device is operating normally; when the indicator light 17 is red, it indicates that the vehicle half-shaft detection device is malfunctioning and needs to be repaired. The heat dissipation hole 18 is used for heat dissipation of the internal components of the detection platform 1.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
