Description

Technical Field

[0001] This utility model belongs to the field of automotive parts quality inspection technology, and in particular relates to a vehicle axle inspection device. Background Technology

[0002] As a key load-bearing and force-transmitting component of the automobile chassis, the surface quality of the axle directly affects the safety, reliability, and durability of the entire vehicle. Surface inspection mainly focuses on checking parameters such as the axle's dimensions, hole positions, angles, and the presence of surface defects.

[0003] Currently, the most common surface inspection methods are visual inspection and dimensional and geometric measurement, which are mostly carried out manually. However, manual inspection has many problems: inspectors are prone to missed or incorrect inspections due to visual fatigue; inspection accuracy is greatly affected by human factors; inspection efficiency is low and cannot meet the needs of modern production; and inspection data is difficult to record and trace digitally. Furthermore, frequent manual intervention is required during the inspection process, further reducing efficiency. In addition, regarding inspection modules, traditional equipment typically uses single-angle camera devices, which are insufficient for comprehensive inspection of the three-dimensional features of the vehicle and axle, easily creating blind spots and affecting the accuracy of the inspection results.

[0004] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0005] The purpose of this invention is to provide a vehicle axle inspection equipment, which has the advantages of improving inspection accuracy and efficiency, realizing automated loading and unloading, and eliminating blind spots in inspection, so as to solve the problems of low efficiency and poor accuracy of manual inspection.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a vehicle axle inspection device, including a workbench, a loading / unloading module, and an inspection module. The loading / unloading module and the inspection module are both installed on the workbench. The loading / unloading module includes a positioning platform for fixing and positioning the vehicle axle. The positioning platform can be driven to slide into or out of the workbench along the Y direction. The inspection module is configured in two groups. The two groups of inspection modules are arranged along the X direction on the workbench and located on both sides of the positioning platform. The inspection module includes multiple cameras, which are arranged in a three-dimensional surround manner.

[0007] Furthermore, the positioning stage includes a sliding base plate and positioning blocks mounted on the top surface of the sliding base plate. The top surface of the positioning blocks is recessed downward along the Z direction to form a bayonet for engaging the axle. Multiple positioning blocks are provided along the Y direction.

[0008] Furthermore, the multiple cameras include side cameras mounted on the workbench and top cameras positioned above the workbench.

There are multiple top cameras, with some top cameras positioned along the Z-axis and the remaining top cameras positioned at an angle to the Z-axis.

[0009] Furthermore, the loading and unloading module also includes a fixed base plate, a drive source, and a slider. The fixed base plate is mounted on the worktable, the drive source is mounted on the fixed base plate and connected to the slider, and the sliding base plate is slidably mounted on the fixed base plate via the slider. The drive source drives the sliding base plate to move along the Y direction via the slider.

[0010] Furthermore, the loading and unloading module also includes linear sliding pairs for guidance and auxiliary support. The sliding base plate is arranged along the X direction, the middle part of the sliding base plate extends backward along the Y direction to form a driving part, and both ends of the sliding base plate extend to the sides along the Y direction to form guide support parts. The slider is connected to the bottom surface of the driving part. Two sets of linear sliding pairs are provided, and the guide support parts at both ends of the sliding base plate are respectively connected to the fixed base plate through the linear sliding pairs.

[0021] The following detailed description illustrates the specific implementation method:

[0022] The reference numerals in the accompanying drawings include: workbench 1, protective cover 2, loading and unloading module 3, detection module 4, sliding base plate 5, drive unit 501, guide support unit 502, positioning block 6, fixed base plate 7, slider 8, linear sliding pair 9, side camera 10, top camera 11, fill light 12, hoisting truss 13.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The basic implementation examples are as follows: Figure 1-5 The diagram shows a vehicle axle inspection device, comprising a workbench 1, a loading / unloading module 3, and an inspection module 4. Both the loading / unloading module 3 and the inspection module 4 are mounted on the workbench 1. The loading / unloading module 3 includes a positioning platform for fixing and positioning the vehicle axle, which can be driven to slide into or out of the workbench 1 along the Y-axis. The inspection module 4 is configured in two groups, positioned along the X-axis on both sides of the positioning platform on the workbench 1. Each inspection module 4 includes multiple cameras arranged in a three-dimensional surround configuration. Specifically, the workbench 1 serves as the basic support structure and can be made of profiles, welded steel structures, etc. The three-dimensional surround camera array allows for simultaneous multi-angle imaging, achieving full-coverage inspection of the vehicle axle surface. This technical solution achieves vehicle axle positioning and automated loading / unloading through a movable positioning platform, combined with a symmetrically arranged multi-camera inspection system, solving the problems of low efficiency and poor consistency in manual inspection. Specifically, the linear movement mechanism of the positioning platform ensures the repeatability accuracy of workpiece positioning, while the three-dimensional surround camera array enables three-dimensional acquisition of vehicle axle surface features. Furthermore, the inspection data can be automatically stored and reports generated, avoiding errors that may occur during manual recording.

[0025] In this embodiment, the positioning platform includes a sliding base plate 5 and positioning blocks 6 mounted on the top surface of the sliding base plate 5. The top surface of the positioning blocks 6 is recessed downward along the Z-direction to form a bayonet for engaging the axle. Multiple positioning blocks 6 are arranged along the Y-direction. Specifically, the sliding base plate 5 serves as the main structure of the positioning platform, supporting and fixing the positioning blocks 6, while also enabling sliding along the Y-direction. The positioning blocks 6 are fixed to the top surface of the sliding base plate 5 by bolts or welding. The shape of the bayonet on its top surface matches the contour of the axle, for example, a V-shaped, U-shaped, or semi-circular groove can be used to ensure that the axle maintains a stable posture during inspection. Multiple positioning blocks 6 are arranged along the Y-direction, and the spacing is adjusted according to the length of the axle and support requirements, thereby achieving compatible support for axles of different lengths. The depth of the bayonet is set to 1 / 3 to 1 / 2 of the axle diameter, which prevents the axle from shifting and facilitates quick loading and unloading. As a preferred embodiment, the positioning blocks 6 can be made of wear-resistant alloy steel and have their surface hardened to extend their service life. Therefore, this technical solution, through the modular design of the positioning block 6, solves the problem of large measurement errors caused by inaccurate axle positioning during manual visual inspection. The combined design of the sliding base plate 5 and the positioning block 6 ensures that the axle maintains a predetermined posture during inspection, avoiding data distortion caused by shaking or displacement. The distributed support of multiple positioning blocks 6 effectively distributes the weight of the axle, preventing local deformation from affecting inspection accuracy and providing stable reference conditions for subsequent visual inspection.

[0026] In this embodiment, the multiple cameras include side cameras 10 mounted on the workbench 1 and top cameras 11 positioned above the workbench 1. Multiple side cameras 10 are provided, with at least one side camera 10 positioned along the X-axis and the remaining side cameras 10 positioned at an angle to the X-axis. Multiple top cameras 11 are provided, with some top cameras 11 positioned along the Z-axis and the remaining top cameras 11 positioned at an angle to the Z-axis. This multi-angle camera combination enables omnidirectional, blind-spot-free image acquisition of the axle surface. The X-axis side cameras 10 are primarily used to acquire overall images of the axle end, while the angled side cameras 10 can capture detailed features at specific angles on the side (such as the size and position of special mounting holes). The Z-axis top cameras 11 are used to acquire planar images of the axle top, while the angled top cameras 11 can capture the transition area between the top and sides. This three-dimensional surround camera arrangement effectively solves the problem of limited viewing angles in traditional manual inspection, improving the comprehensiveness and accuracy of the inspection. By working together with cameras at different angles, the dimensions, holes, angles, and other features of the vehicle axle surface can be fully recorded, providing a reliable image data foundation for subsequent automated inspection.

[0027] In this embodiment, the loading / unloading module 3 further includes a fixed base plate 7, a drive source, and a slider 8. The fixed base plate 7 is mounted on the worktable 1, the drive source is mounted on the fixed base plate 7 and connected to the slider 8, and the sliding base plate 5 is slidably mounted on the fixed base plate 7 via the slider 8. The drive source drives the sliding base plate 5 to move along the Y direction via the slider 8. Specifically, the sliding base plate 5 is driven by the drive source directly through the slider 8, thereby achieving precise positioning and stable transmission. As a preferred embodiment, the drive source uses a servo motor combined with a ball screw structure, wherein the servo motor is connected to the ball screw through a coupling, and the nut of the ball screw is fixedly connected to the slider 8. This structure has the characteristics of high transmission accuracy and fast response speed, which can meet the positioning accuracy requirements in the vehicle axle inspection process. This technical solution solves the problem of insufficient positioning accuracy in the traditional manual loading / unloading process through a modular drive structure design. Due to the adoption of a mechanized drive method, errors caused by manual operation are avoided, while inspection efficiency is improved. The cooperation structure between the slider 8 and the fixed base plate 7 ensures the smoothness of the movement of the sliding base plate 5, while the direct drive method of the drive source provides sufficient driving force and positioning accuracy.

[0028] In this embodiment, the loading / unloading module 3 further includes a linear sliding pair 9 for guidance and auxiliary support. The sliding base plate 5 is arranged along the X-direction, with its middle portion extending rearward along the Y-direction to form a driving part 501. Both ends of the sliding base plate 5 extend laterally along the Y-direction to form guide support parts 502. The slider 8 is connected to the bottom surface of the driving part 501. Two sets of linear sliding pairs 9 are provided, with the guide support parts 502 at both ends of the sliding base plate 5 respectively connected to the fixed base plate 7 via the linear sliding pairs 9. Specifically, the linear sliding pair 9 can be implemented using ball linear guides, roller linear guides, or sliding bearing guides. The extension length of the guide support part 502 can be adjusted according to the size of the sliding base plate 5 and the load requirements. The specific shape of the driving part 501 can be a rectangular plate, a trapezoidal plate, or other shapes suitable for connection with the slider 8. The installation methods of the linear sliding pair 9 include, but are not limited to, bolt fixing, welding fixing, or embedded installation. Thus, this technical solution effectively solves the problems of guiding accuracy and support stability during long-stroke movement by setting the linear sliding pair 9 and the sliding base plate 5 with a specific shape. Specifically, the guide support sections 502 extending at both ends, together with the linear sliding pair 9, form a double-support structure, significantly improving the stability of the sliding base plate 5 during movement. The drive section 501 located in the middle enables centralized transmission of driving force, avoiding movement jamming caused by uneven force distribution. Compared with a single-sided support structure, this design allows the sliding base plate 5 to maintain smooth movement under load, ensuring the accuracy of axle positioning. In addition, the modular design facilitates maintenance and component replacement, improving the maintainability of the equipment.

[0029] In this embodiment, the detection module 4 also includes a hoisting truss 13 fixedly installed on the workbench 1, through which multiple top-facing cameras 11 are hoisted to the workbench 1. Specifically, the hoisting truss 13 is a rigid frame structure, which can be assembled from welded steel beams or aluminum alloy profiles, and its bottom is fixed to the preset mounting holes on the workbench 1 by bolts. As a preferred embodiment, the top of the truss is provided with an adjustable camera mounting bracket, which can be finely adjusted in position along the X / Y / Z axes. The top-facing cameras 11 are connected to the bracket via quick-release interfaces. This technical solution achieves modular hoisting of the top-facing camera group 11 through a truss structure, solving the technical problem of maintaining the spatial positioning accuracy of multiple cameras. Specifically, the rigid truss can eliminate the vibration transmission problem existing in traditional independent brackets, and ensures that all top-facing cameras 11 have a consistent spatial coordinate system through a unified reference mounting surface. Compared with split brackets, this integrated hoisting solution significantly improves the spatial positional stability of the camera group.

[0030] In this embodiment, the detection module 4 also includes multiple supplementary lights 12, which are distributed across the worktable 1. Specifically, the supplementary lights 12 serve as auxiliary lighting devices, primarily providing sufficient and uniform illumination for camera capture. The supplementary lights 12 can utilize LED light sources, offering advantages such as low energy consumption, long lifespan, and adjustable brightness. In a preferred embodiment, the illumination angle of the supplementary lights 12 is adjustable to ensure that the light covers the surface of the axle to be inspected. The brightness of the supplementary lights 12 can be adjusted according to actual detection needs to adapt to the inspection of axle surfaces of different materials and colors. This technical solution, by adding supplementary lights 12 to the detection module 4, effectively solves the problem of poor image quality caused by insufficient or uneven illumination during axle surface inspection. The arrangement of the supplementary lights 12 provides a stable lighting environment for the camera, ensuring that the captured axle surface images are clear and detailed, thereby improving the accuracy and reliability of the inspection.

[0031] This embodiment also includes a protective cover 2, which is installed on the workbench 1. The loading / unloading module 3 and the detection module 4 are both housed within the protective cover 2. The protective cover 2 has a door for the positioning platform to slide in or out. Specifically, the protective cover 2 can be made of welded metal sheet or transparent or semi-transparent polycarbonate material to facilitate observation of the internal detection process. The door can be designed as an automatic sliding door or a manually opening door. The protective cover 2 must completely cover the loading / unloading module 3 and the detection module 4. This technical solution, by setting the protective cover 2, encloses the loading / unloading module 3 and the detection module 4 inside the workbench 1, effectively isolating the external environment from interference with the detection process, such as dust and changes in light. The door design of the protective cover 2 allows the positioning platform to slide in or out smoothly without affecting normal loading / unloading operations. The protective cover 2 also enhances the safety of the equipment, preventing operators from accidentally contacting moving parts or suffering other injuries.
