Description

Technical Field

[0001] The utility model relates to the technical field of measurement, in particular to a rim size detection device. Background Art

[0002] In the automotive industry, the geometric accuracy of wheel rims directly impacts vehicle safety and performance. Traditional inspection methods, which rely primarily on manual caliper measurement or semi-automatic inspection stations, suffer from low efficiency and poor consistency. Especially with the increasing prevalence of multi-product flexible production and the increasing diversity of wheel rim specifications, existing equipment struggles to balance inspection accuracy and changeover efficiency.

[0003] Currently, mainstream automated inspection equipment typically uses fixed measuring fixtures, which present significant limitations in the inspection process: manual adjustment of the rim's posture during loading requires time delays; centering often relies on mechanical stoppers, requiring fixture changes for different rim sizes, interrupting production line operations; and scanning critical dimensions often requires multiple clampings, which can lead to cumulative errors. A more prominent limitation is that, to meet full-size inspection requirements, traditional solutions require rims to be transported between different workstations, resulting in single-piece inspection times of up to several minutes, creating a production line bottleneck.

[0004] While the recent emergence of laser scanning technology has increased inspection speed, practical applications are still hampered by two issues: First, inconsistent measurement benchmarks lead to measurement drift due to differential rim deformation between the clamped and free states. Second, a stable mid-air positioning solution is lacking during dynamic inspection, as even slight rim vibrations can distort laser point cloud data. The industry urgently needs an integrated solution that can simultaneously perform high-precision positioning, multi-reference calibration, and fully automated scanning in continuous production to overcome the dual constraints of rim inspection efficiency and accuracy.

[0005] The development status of this technology field shows that simply improving the measurement method cannot systematically solve the problem. The entire process logic must be reconstructed, especially to resolve the contradictory relationship between the rigid support and free deformation of the rim during the inspection process.

[0029] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0030] The present invention is described in further detail below with reference to the accompanying drawings:

[0031] like Figure 1 and Figure 2 As shown, a wheel rim size detection device provided by the present invention includes: a transmission component, a positioning component, a measurement reference component and a scanning detection component;

[0032] The transmission assembly is used to transmit the rim 7 to a preset inspection station, which includes a lifting inspection platform 6. The lifting inspection platform 6 can lift the rim 7 to a preset height.

[0033] The positioning assembly is used to position the rim 7 on the inspection station;

[0034] The measurement reference assembly is used to fix a preset measurement reference position on the rim 7;

[0035] The scanning module of the scanning detection assembly moves along a preset trajectory relative to the rim 7 to perform multi-point position scanning detection;

[0036] The transmission component is also used to transport the inspected rim 7 to the discharge port.

[0037] In this embodiment, the transmission component is used to realize unmanned operation of the entire process of the rim 7 from feeding, detection to sorting, which significantly reduces the need for manual intervention to adapt to the continuous production rhythm. The reference point of the rim 7 is accurately locked by the measurement reference component in conjunction with the positioning component to establish a unified coordinate system. The rim 7 is scanned and detected at multiple angles by the scanning and detection component. Based on the unified measurement reference, data drift caused by changes in the clamping position is reduced, the accuracy of the rim size detection is improved, and the reliability and efficiency of the detection process are improved.

[0038] Specifically, the outer side of the entire wheel rim size detection device may adopt a shell module of a box structure, and a control component and a display component may be set on the box panel, and a cooling fan may also be set on the box.

[0039] Among them, the transmission component cooperates with the relative position relationship of the positioning component, the measurement reference component and the scanning detection component, and can transmit the rim 7 from the feed port to the detection station, and can output the detected rim 7 to the discharge port.

[0040] After the rim 7 reaches the inspection station, the positioning assembly can clamp the rim 7 lifted by the jacking inspection platform 6 to achieve centering, and then release the clamping operation, and the rim 7 is in the positioned position.

[0041] After the positioning is completed, for example, using the upper part of the outer edge of the rim 7 as the measurement reference, the rim 7 can be further lifted by the lifting detection platform 6 to reach a predetermined detection height. The measurement reference component can then clamp the measurement reference of the rim 7 for the scanning detection component to perform scanning detection based on the measurement reference.

[0042] When the measurement reference assembly is clamped, rim 7 is suspended in mid-air. The scanning modules of the scanning and inspection assembly move relative to rim 7 along a pre-set trajectory. Multiple scanning modules can be provided, for example, with separate scanning modules for the outside and inside of the rim. Once the measurement reference assembly has clamped rim 7, the scanning modules move relative to rim 7, scanning and inspecting multiple points inside and outside the rim along the pre-set trajectory based on the measurement reference.

[0043] During the inspection process, the upper scanning module can be extended into the inner side of the rim 7, the lifting inspection platform 6 is lowered, and after the rim 7 adjusts to the inspection state, the scanning modules on the inner and outer sides simultaneously perform internal and external scanning. After completing a position scan, the lifting inspection platform 6 is raised, and the lifting rim 7 is separated from the measurement reference clamping, rotated a certain angle, and the lifting inspection platform 6 is lowered again, so that the rim 7 continues to be clamped with the measurement reference as the support, and another scan is performed. Multi-point position scanning and inspection can be performed as needed in one week.

[0044] like Figure 3 As shown, in the above embodiment, preferably, the transmission component includes a conveyor belt module 1, the rim 7 is placed on the belt of the conveyor belt module 1, and the conveyor belt module 1 can drive the rim 7 to move to a preset position.

[0045] Specifically, the belts are arranged on both sides of the jacking detection platform 6. When the jacking detection platform 6 is in the initial position, the surface of the jacking detection platform 6 is lower than the upper surface of the belt, preventing the rim 7 transmitted on the belt from being blocked by the jacking detection platform 6 during the transmission process.

[0046] like Figures 1 to 3As shown, in the above embodiment, preferably, the positioning component includes a centering clamping module 2, and the centering clamping module 2 performs centering clamping relative to the rim 7 on the jacking detection platform 6, that is, the rim 7 is pushed toward the middle of the centering clamping module 2, and the middle point of the centering clamping module 2 is used as the positioning point of the rim 7, and the clamping of the rim 7 is released after the positioning is completed.

[0047] Specifically, when the rim 7 is placed on the belt and the jacking test platform 6, there may be deviations in the position. By clamping the centering clamping module 2 from both sides to the middle, the position of the rim 7 can be positioned during different testing processes.

[0048] like Figure 4 As shown, in the above embodiment, preferably, the measurement reference assembly includes a reference clamping module 3, and the reference clamping module 3 clamps the rim 7 at a preset reference position after positioning.

[0049] Specifically, for a circular rim, the reference clamping module 3 can clamp the rim 7 at a pre-set measurement reference position on the rim 7, such as the upper edge of the outer side of the rim, so that the scanning detection component can perform scanning detection based on the measurement reference.

[0050] like Figure 5 As shown, in the above embodiment, preferably, the scanning and detection component includes a laser scanning module 4 and a driving gantry component 5, the laser scanning module 4 is respectively arranged relative to the inner and outer sides of the rim 7, and the driving gantry component 5 can drive the laser scanning module 4 to perform scanning and detection relative to the inner and outer sides of the rim 7;

[0051] The lifting detection platform 6 can also drive the rim 7 to move up and down and rotate relative to the laser scanning module 4.

[0052] Specifically, the driving gantry assembly 5 can drive the laser scanning module 4 to move at the detection station, and can move and scan relative to the rim 7 according to a preset trajectory. At the same time, after the scanning of some points is completed, the jacking detection platform 6 can also drive the rim 7 to move up and down and rotate, so that the laser scanning module 4 can scan the remaining points, or repeat the scan of the rim 7.

[0053] In the above embodiment, preferably, the reference clamping module 3 performs a clamping action while the jacking detection platform 6 jacks up the rim 7, and the scanning detection component simultaneously moves to the initial scanning position of the rim 7 and is able to complete the clamping when the rim 7 is jacked into place, and at the same time;

[0054] When the rim 7 is lifted into position, the reference clamping module 3 can complete the clamping, and at the same time, the scanning and detection component can start scanning and detecting along a preset trajectory.

[0055] Specifically, by pre-designing the relative position relationship between the transmission component and the positioning component, the measurement reference component and the scanning detection component, the lifting action of the lifting detection platform 6, the clamping action of the reference clamping module 3 and the moving scanning action of the scanning detection component can be executed in a predetermined rhythm sequence, so that the actions of each part are carried out simultaneously, the running time can be merged, and the detection efficiency is improved.

[0056] In the above embodiment, preferably, the transmission component also includes an inlet lifting door plate and an outlet lifting door plate. The inlet lifting door plate is arranged at the inlet of the rim 7, and the outlet lifting door plate is arranged at the outlet of the rim 7. The inlet lifting door plate and the outlet lifting door plate are only opened during feeding and discharging to prevent the oil, gas, smoke and blown iron filings at the detection site from entering the equipment and causing pollution to the scanning and detection components. The inlet and outlet are respectively arranged on the front and rear side panels of the carriage of the conveyor belt module 1, and are connected to the logistics lines of other processes on site.

[0057] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
