[0003] However, due to the irregularity of the sheet metal part surface, traditional detection tools and detection methods cannot perform precise measurements, and they lack flexibility. When multiple positions need to be detected, the detection mechanism needs to be repeatedly operated, seriously affecting the detection efficiency and resulting in low detection efficiency. Summary of the Invention

[0027] Please refer to Figures 1 to 3 , an embodiment of the present application provides a detection device 100 for detecting a workpiece 101. Among them, the workpiece 101 can be a component on an automobile, such as a sheet metal part or a plastic part. In this embodiment, the workpiece 101 is a sheet metal part of an automobile sunroof glass, and the bending radian and bending height of the workpiece 101 can be detected by the detection device 100.

[0028] Please refer to Figures 1 to 3, the detection device 100 includes: a fixed platform 10, a detection member 30, and a positioning member 20. The fixed platform 10 can be arranged on the workbench and maintained horizontally. The fixed platform 10 has an upwardly disposed mounting surface 121, and the shape of the mounting surface 121 is adapted to the workpiece 101. That is, when the workpiece 101 has a certain bending curvature, the mounting surface 121 is a concave arc surface, so that one side surface of the workpiece 101 fits the mounting surface 121, that is, the convex side surface of the workpiece 101 is disposed on the mounting surface 121. The positioning member 20 is used to press and position the workpiece 101 on the mounting surface 121, so that the workpiece 101 and the mounting surface 121 can remain stable during subsequent detection, effectively eliminating the positioning error caused by poor contact between the irregular surface of the workpiece 101 and the mounting surface 121. The detection member 30 is connected to the fixed platform 10 and is used to detect the workpiece 101. For example, it detects the bending curvature and bending height of the workpiece 101. A plurality of the detection members 30 are arranged at intervals along the length direction of the workpiece 101. Through the plurality of detection members 30, the workpiece 101 can be detected at multiple positions simultaneously, improving the detection efficiency, and enabling each detection member 30 to perform detection based on the same reference, eliminating the error of repeated positioning, thereby improving the preparation and detection accuracy of the detection.

[0029] Please refer to Figures 1 to 3 , the detection device 100 provided in this embodiment can detect the profile panel with an irregular shape through the combination of the fixed platform 10, the detection member 30, and the positioning member 20. The positioning member 20 presses and fixes the workpiece 101 on the mounting surface 121, improving the stability during the detection process. The design of arranging a plurality of the detection members 30 at intervals along the length direction of the workpiece 101 enables the device to cover multiple detection points of the workpiece 101 at one time and can achieve parallel detection, shortening the detection cycle, and having good detection accuracy, high detection efficiency, and flexibility.

[0030] Please refer to Figures 1 to 3 , optionally, the fixed platform 10 includes a fixing plate 11 laid flat on the workbench and a detection table 12 arranged on the fixing plate 11, and the mounting surface 121 is located on the detection table 12. The upper surface of the fixing plate 11 is a plane. Taking the upper surface of the fixing plate 11 as the reference surface, the bending curvature refers to the bending degree of the surface to be detected of the workpiece 101 relative to the upper surface of the fixing plate 11, and the bending height refers to the distance from the detection point on the surface to be detected of the workpiece 101 to the upper surface of the fixing plate 11.

[0031] Please refer to Figures 4 to 5 , optionally, the detection table 12 is detachably connected to the fixing plate 11. For example, through bolts, the detachable connection between the detection table 12 and the fixing plate 11 can be realized. By replacing different detection tables 12, different workpieces 101 can be detected.

[0032] Please refer to Figures 1 to 3 In some embodiments, the detecting member 30 includes a fixing seat 33 connected to the fixed platform 10, a turning arm 32 rotatably connected to the fixing seat 33, and a dial indicator 31 connected to the turning arm 32. The turning arm 32 rotates relative to the fixing seat 33 by a predetermined angle so that the detecting end of the dial indicator 31 abuts against or disengages from the workpiece 101. The predetermined angle can be 60 degrees, 90 degrees or 120 degrees, which is not limited here and can be selected according to actual situations.

[0033] Please refer to Figures 1 to 3 Optionally, a through hole is formed in the fixing plate 11, and the fixing seat 33 can be connected to the fixing plate 11 by bolts. The plane determined by the rotation trajectory of the turning arm 32 is perpendicular to the upper plate surface of the fixing plate 11. By using the flexibility of the rotation of the turning arm 32, the detecting end of the dial indicator 31 can quickly adjust the contact state with the workpiece 101. By rotating the turning arm 32, the operator only needs to simply adjust the angle to make the detecting end of the dial indicator 31 abut against or disengage from the workpiece 101, and it can adapt to workpieces 101 of different thicknesses, simplifying the operation process and improving the detection efficiency.

[0034] Please refer to Figures 1 to 3 Optionally, as a high-precision measuring tool, the dial indicator 31 can detect minute deformations or dimensional deviations on the surface of the workpiece 101, and the stability of its detecting end directly affects the reliability of the measurement results. The rotational setting of the turning arm 32 ensures the smoothness when the detecting end contacts the workpiece 101, avoiding errors caused by tool shaking or improper angles. For example, when detecting the flatness of an automobile body sheet metal part, this design can quickly locate the key parts of the workpiece 101, ensuring the accuracy of the measurement data, thereby providing a scientific basis for quality control.

[0035] Please refer to Figures 1 to 3 It can be understood that automobile sheet metal parts have various shapes and diverse detection requirements. Traditional tools are often difficult to handle complex workpieces 101 due to their single functions, while the rotational function of the turning arm 32 enables the detecting member 30 to adapt to measurement requirements at different angles and positions. For example, when detecting the edge curve of a car door panel, the operator can adjust the angle of the turning arm 32 to make the detecting end of the dial indicator 31 precisely abut against the curve part, improving the versatility of the detecting device 100.

[0036] Optionally, the detection result can be directly read through the dial indicator 31 to visualize the detection result. Among them, the display directions of some of the dial indicators 31 are opposite to those of the other part of the dial indicators 31, so that part of the detection result can be directly observed from one end of the workpiece 101, and the other part of the detection result can be observed from the other end of the workpiece 101, improving the convenience of observing the detection result.

[0037] Please refer to Figures 1 to 3 , in some embodiments, the fixed seat 33 is provided with a transfer groove, and one end of the flipping arm 32 is rotatably arranged in the transfer groove.

[0038] Optionally, the flipping arm 32 can be rotatably connected to the transfer groove through a rotating shaft. For example, both ends of the rotating shaft are respectively connected to the groove walls on the opposite sides of the transfer groove, and a rotating hole is provided on the flipping arm 32, and the rotating shaft passes through the rotating hole, so that the rotating shaft serves as the rotation fulcrum of the flipping arm 32, enhancing the overall structural stability of the detection member 30, and also ensuring the rotation consistency of the flipping arm 32 during repeated operations, so that the detection end of the dial indicator 31 can maintain precise alignment with the point to be detected on the workpiece 101.

[0039] Optionally, the materials of the fixed platform 10, the positioning member 20, the flipping arm 32 and the fixed seat 33 can be structural steel, so as to reduce the weight of the detection device 100.

[0040] Please refer to Figures 1 to 3 , in some embodiments, a fixing hole is provided at one end of the flipping arm 32 away from the fixed seat 33, and the dial indicator 31 is fixed in the fixing hole.

[0041] Optionally, the fixing hole provides a stable support for the installation of the dial indicator 31. The detection end of the dial indicator 31 passes through the fixing hole so that the dial indicator 31 is fixed in the fixing hole, ensuring the stability of the detection end of the dial indicator 31 during the measurement process.

[0042] Please refer to Figures 4 to 5 , as a precision instrument, the measurement accuracy of the dial indicator 31 highly depends on the fixity of the installation position. If the detection end deviates from the surface of the workpiece 101 due to shaking or loosening, the measurement data will lose reliability. The fixing hole firmly embeds the dial indicator 31 into the flipping arm 32, preventing the dial indicator 31 from loosening during the detection process, so that the detection end of the dial indicator 31 can always maintain stable contact with the workpiece 101, ensuring the accuracy of the measurement result.

[0043] In actual operation, the existence of the fixing hole makes the installation and disassembly process of the dial indicator 31 simple and efficient. The operator only needs to insert the dial indicator 31 into the fixing hole and lock it with bolts or other fixing parts to complete the assembly, without complex tools or cumbersome steps.

[0044] Please refer toFigures 1 to 3 In some embodiments, the detection members 30 are arranged at equal intervals along the length direction of the workpiece 101 .

[0045] See also Figures 1 to 3 Optionally, arranging multiple detection members 30 at equal intervals can improve the comparability and reliability of the detection results. Since the intervals between the detection members 30 are fixed, the data collected at each detection point have a consistent reference benchmark, which is convenient for operators or subsequent analysis systems to evaluate the overall quality of the workpiece 101. For example, when detecting the flatness of a car body panel, the equally spaced detection members 30 can clearly reflect whether there are local bumps or deformations on the surface of the workpiece 101, avoiding the risk of misjudgment caused by the randomness of the detection points in traditional detection.

[0046] See also Figures 4 to 5 For workpieces 101 of different lengths or specifications, the number or spacing of the detection parts 30 can be adjusted as needed to achieve adaptation, and the principle of equal spacing ensures that the detection after adjustment remains uniform. For example, when detecting side panels of different models, the length of the workpiece 101 can be adapted by increasing or decreasing the number of detection parts 30. This flexibility enables the detection device 100 to be widely used in the detection scenarios of various automotive parts.

[0047] See also Figures 1 to 3 In some embodiments, the positioning member 20 includes a positioning seat 23 connected to the fixed platform 10 and located at one end of the workpiece 101 and a clamping arm 21 having one end rotatably connected to the positioning seat 23, and the other end of the clamping arm 21 presses the workpiece 101 toward the mounting surface 121.

[0048] Optionally, the positioning seat 23 is connected to the fixed plate 11. Similarly, a connecting hole can be opened on the fixed plate 11, and the positioning seat is penetrated by bolts to connect to the fixed plate 11. The connecting hole can be a waist-shaped hole, and the position of the positioning seat 23 can be fine-tuned. The adjustment direction is along the length direction of the workpiece 101, so that the positioning member 20 can adapt to workpieces 101 of different lengths.

[0049] See also Figures 1 to 3 It can be understood that the rotation setting of the clamping arm 21 enables it to flexibly adapt to the irregular shape of the workpiece 101, ensuring that the clamping force is evenly distributed on the surface of the workpiece 101. For example, when inspecting a door panel, the clamping arm 21 can adjust the angle according to the curve of the edge of the workpiece 101, so that the clamping point fits tightly with the workpiece 101, avoiding the deviation or shaking caused by poor contact in the traditional fixing method, and improving the stability of the workpiece 101 during the inspection process.

[0050] See also Figures 1 to 3, the positioning member 20 further includes a handle 22 for driving the pressing arm 21. By manually operating the handle 22, the pressing arm 21 can be driven to abut against the workpiece 101 or the workpiece 101 can be driven to disengage from the workpiece 101. A spring can be provided on the positioning seat 23, and the pressing arm 21 can be kept pressed against the workpiece 101 by the elastic force of the spring. For example, one end of the spring can be connected to the positioning seat 23, and the other end of the spring can be connected to the pressing arm 21, and the spring is kept in a stretched state.

[0051] Please refer to Figures 1 to 3 , in some embodiments, the pressing arm 21 includes a pressing rod 211 rotatably connected to the positioning seat 23 and a pressing head 212 connected to the pressing rod 211 and abutting against the workpiece 101.

[0052] Optionally, by rotating the pressing rod 211, the pressing head 212 can be flexibly driven to rotate together, so that the pressing head 212 has a flexible adjustment ability and can quickly adjust the pressing angle according to the shape and position of the workpiece 101. That is, the rotation function of the pressing rod 211 enables the pressing arm 21 to adapt to workpieces 101 of different shapes.

[0053] Please refer to Figures 1 to 3 , optionally, two pressing heads 212 are arranged at intervals. The two pressing heads 212 can both abut against the workpiece 101, so as to avoid excessive pressure concentration on the workpiece 101. At the same time, multiple pressing heads 212 can improve the stability of the fit between the workpiece 101 and the mounting surface 121.

[0054] Please refer to Figures 1 to 3 , in some embodiments, two positioning members 20 are provided, and the two positioning members 20 are arranged at intervals along the length direction of the workpiece 101.

[0055] Optionally, the two positioning members 20 respectively press the workpiece 101 at both ends of the workpiece 101, improving the stability of the workpiece 101 during the detection process. In this embodiment, by providing two positioning members 20 at both ends or key positions of the workpiece 101, a double-point support structure is formed, effectively dispersing the pressing force, ensuring that the whole workpiece 101 fits the mounting surface 121, and avoiding problems such as offset or tilt that may occur in single-point positioning.

[0056] Please refer to Figures 1 to 3 , in addition, for sheet metal parts with different lengths or shapes, the distance between the two positioning members 20 can be adjusted as needed to adapt to the size of the workpiece 101. For example, when detecting a small car door panel, the distance between the positioning members 20 can be appropriately shortened, while when detecting a large car roof panel, the distance can be lengthened. This flexibility enhances the versatility of the detection device 100.

[0057] Please refer to Figures 1 to 3, in some embodiments, a first limiting hole is formed at one end of the workpiece 101, and a limiting post 14 protrudes from the mounting surface 121 corresponding to the position of the first limiting hole.

[0058] Please refer to Figures 1 to 3 , optionally, by using the first limiting hole as a reference hole and through the fitting of the first limiting hole and the limiting post 14, the alignment of the workpiece 101 on the mounting surface 121 can be quickly achieved, improving the detection efficiency. For example, when detecting an automotive door panel, the operator only needs to align the first limiting hole of the workpiece 101 with the limiting post 14 and insert it, and the preliminary positioning can be completed in a few seconds without repeatedly adjusting the angle or position of the workpiece 101. The setting of the limiting post 14 also enhances the fixing effect of the workpiece 101 during the detection process. The fitting of the first limiting hole and the limiting post 14 forms a constraint point, which can effectively limit the movement of the workpiece 101 in the horizontal direction. Combined with the pressing force of the positioning member 20, the stability of the workpiece 101 is further ensured.

[0059] Please refer to Figures 1 to 3 , in some embodiments, a second limiting hole is further formed at the other end of the workpiece 101, a third limiting hole is formed at the mounting surface 121 corresponding to the position of the second limiting hole, and the detection device 100 further includes a positioning pin 13. One end of the positioning pin 13 passes through the second limiting hole and is inserted into the third limiting hole.

[0060] Please refer to Figures 1 to 3 , optionally, by providing a second limiting hole at the other end of the workpiece 101 and cooperating with the third limiting hole and the positioning pin 13 on the mounting surface 121, a double-end limiting structure is formed. The double-end limiting can apply binding forces simultaneously at both ends of the workpiece 101, effectively preventing the workpiece 101 from warping, shifting or rotating during the detection process due to its long length or uneven stress.

[0061] In actual operation, the plug-and-play design of the positioning pin 13 makes the fixing and disassembling process of the workpiece 101 simple and fast. The operator only needs to align the second limiting hole of the workpiece 101 with the third limiting hole and insert the positioning pin 13 to complete the fixing, without complex tools or cumbersome steps.

[0062] The above are only optional embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application.
