With the rapid development of the automotive industry and the increasing demands of consumers for vehicle quality, automakers have also set more stringent standards for the production precision and quality control of the rear side panel assembly.

[0003] Currently, in the production process of automotive rear side panel assemblies, most companies still rely on traditional manual measurement methods for dimensional inspection. Specifically, inspectors need to use conventional measuring tools such as calipers and micrometers to measure each key dimension of the rear side panel assembly and compare it with the standard dimensions on the design drawings to determine whether the product meets quality requirements.

[0004] However, during manual inspection, the complex structure of the rear side panel assembly of a car, which includes numerous dimensional features of different shapes and positions, requires inspectors to accurately measure and record each feature. This makes manual measurement extremely time-consuming and labor-intensive, resulting in low inspection efficiency. Furthermore, the data obtained through manual measurement is subject to fluctuations and deviations due to the inspectors' professional skills and experience, such as their operating techniques and errors in visual judgment. This makes it difficult to guarantee the accuracy and consistency of the measurement results.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0026] In one embodiment of this utility model, such as Figures 1-3As shown, a flexible inspection tool for an automotive side panel inner panel is provided, including a frame 10, a contouring base 11, a fixing mechanism, and a flatness detection assembly 40. A worktable 101 is provided on the frame 10. The contouring base 11 is detachably mounted on the worktable 101 for placing the side panel inner panel. A measurement module (not shown) for inspection is provided on one side of the worktable 101 corresponding to the contouring base 11. The fixing mechanism includes locking components 20 and clamping components 30. Multiple sets of locking components 20 are disposed within the contouring base 11 for fixing the side panel inner panel. The locking components 20 are located on the outer edge of the contouring base 11 for pressing the outer edge of the side panel inner panel onto the contouring base 11. Multiple sets of flatness detection assemblies 40 are located on the outer edge of the contouring base 11 for detecting the flatness of the side surface of the side panel inner panel.

[0027] By incorporating a contouring base 11, a locking assembly 20, and a clamping assembly 30, the inner side panel can be quickly and accurately positioned and securely fixed to the contouring base 11. Compared to manual inspection, which requires constant adjustment of the part's position and the use of multiple clamps for fixation, the flexible fixture shortens the clamping time and improves pre-inspection preparation efficiency. Simultaneously, the multiple contouring blocks of the contouring base 11 accurately simulate the shape and position of the inner side panel, providing an accurate benchmark for measurement. Furthermore, the measurement module and flatness detection assembly 40 accurately measure the part, avoiding the influence of human visual judgment errors on the measurement results and reducing measurement deviations caused by human factors.

[0028] Preferably, the locking assembly 20 includes multiple sets of fixing platforms 21 and multiple sets of locking bolts 22. Each set of fixing platforms 21 is located within the contour base 11. Each set of locking bolts 22 is correspondingly located on each set of fixing platforms 21, and the locking bolts 22 can enter or disengage from the fixing platforms 21. By setting the fixing platforms 21 and locking bolts 22, the threaded connection between the two allows the inner side panel to be stably and accurately fixed to the contour base 11, avoiding problems caused by differences in manual operation techniques, ensuring the positional stability of the parts during the inspection process, and thus improving the accuracy of the measurement data.

[0029] Furthermore, the fixing platform 21 is provided with threaded holes. The connecting end of the locking bolt 22 is provided with a threaded part that is threadedly connected to the threaded hole. By providing threaded holes and threaded parts, it is more convenient to fix and remove the inner side panel on the contour base 11, thereby improving the fixing efficiency of the inner side panel and thus improving the inspection efficiency of the inner side panel.

[0030] Preferably, the clamping assembly 30 includes a clamp seat 31 and a pressure block 32. The clamp seat 31 is disposed on the worktable 101 and located on the outer edge of the contour base 11. The pressure block 32 is disposed on the clamp seat 31, and the contour base 11 is provided with an abutment block 111 corresponding to the pressure block 32. By setting the clamp seat 31 and the pressure block 32, the clamp seat 31 controls the pressure block 32 to move away from or press against the inner side panel, so that the inner side panel can be quickly disassembled or installed on the contour base 11, realizing flexible clamping between the inner side panel and the contour base 11, simplifying the installation and disassembly steps.

[0031] Furthermore, the clamp base 31 includes a fixed base 311, a pull rod 312, and a swing rod 313. The fixed base 311 is mounted on the worktable 101 via a fixed bracket 33. One end of the swing rod 313 is rotatably connected to the fixed base 311, and the other end is fixedly connected to the pressure block 32. One end of the pull rod 312 is rotatably connected to the fixed base 311. The swing rod 313 and the pull rod 312 are fixedly connected, and the swing rod 313 and the pull rod 312 are arranged perpendicularly. By setting the swing rod 313 and the pull rod 312, the linkage between the two can precisely control the pressure block 32 to move away from or press against the inner side panel, realizing its quick disassembly or installation on the contour base 11, simplifying its installation and disassembly steps.

[0032] Preferably, the flatness detection assembly 40 includes a detector 41 and a fixing block 42. The fixing block 42 is fixedly connected to one side of the contour base 11 by screws. The detector 41 is tightly connected to the contour base 11. The detector 41 can be a dial indicator or other flatness detection instrument. By setting the detector 41, accurate and stable flatness detection can be achieved, avoiding the influence of human visual judgment error on the measurement results, reducing measurement deviations caused by human factors, and ensuring the accuracy and consistency of the measurement results.

[0033] Furthermore, through holes are provided between the fixing block 42 and the contour base 11. The detection end of the detector 41 passes through the through hole and extends to the other side of the contour base 11. By providing through holes, the detection end of the detector 41 can accurately reach the detection position, realizing precise and stable flatness detection, avoiding the influence of human visual judgment error on the measurement results, reducing measurement deviation caused by human factors, and ensuring the accuracy and consistency of the measurement results.

[0034] Preferably, the contour base 11 includes multiple sets of contour blocks corresponding to the inner side panel, and these sets of contour blocks are connected end-to-end. The contour blocks are detachably connected to the worktable 101 via a contour bracket. By setting multiple sets of contour blocks, the shape and position of the inner side panel can be accurately simulated, providing an accurate and stable reference for measurement. This allows measurement personnel to perform dimensional measurements more accurately, avoiding measurement errors caused by inaccurate references and improving the accuracy and consistency of measurement results. Simultaneously, the detachable connection design of the contour blocks facilitates quick replacement and adjustment according to different models of inner side panels, improving the versatility and adaptability of the inspection tool.

[0035] Preferably, the measurement module is a coordinate measuring machine (CMM). By using the measurement module of a CMM, it has high-precision and automated measurement capabilities, enabling comprehensive and accurate measurement of parts. It is unaffected by errors in manual operation and visual judgment, greatly improving the accuracy and consistency of measurement results and effectively solving the problem of inaccurate and inconsistent data from manual inspection.
