[0030] In one embodiment of this utility model, such as Figures 1-8 As shown, a hood assembly inspection fixture is provided, including a frame 10, a contour base 20, a hole detection component, and a slot detection component. A worktable 11 is provided on the frame 10. The contour base 20 is disposed on the worktable 11 and is used to place the hood 12. Multiple sets of fixing components 50 for fixing the top surface of the hood 12 are provided on the contour base 20. A bottom surface detection rod 26 for detecting the bottom surface of the hood 12 is provided inside the contour base 20, and the bottom surface detection rod 26 is disposed opposite to the fixing components 50. Multiple sets of support blocks 13 for supporting the hood 12 are provided inside the contour base 20 corresponding to the frame 10. The hole detection component is disposed on the frame 10 and located inside the contour base 20, and is used to detect holes on the hood 12. The slot detection component is disposed on the frame 10 and located inside the contour base 20, and is used to detect slots on the hood 12.

[0031] By setting up a bottom surface inspection rod 26, a hole position inspection component, and a slot position inspection component, and integrating these components onto the frame 10, centralized inspection of the holes and slots of the hood 12 is achieved. Specifically, the inspector only needs to place the hood 12 on the contour base 20 and observe the inspection status of each inspection module to complete multiple inspection items, greatly reducing inspection procedures and time, significantly improving inspection efficiency, thereby shortening the overall operating time of the automobile production line and improving the overall efficiency of the production line.

[0032] Preferably, the hole position detection assembly includes a first hole position detection component 30 and a second hole position detection component 31. The first hole position detection component 30 is disposed inside the contour base 20 and is used for detecting holes or round holes on the top of the hood 12. The second hole position detection component 31 is disposed inside the contour base 20 and is used for detecting round holes on the upper side of the hood 12. By setting the first hole position detection component 30 and the second hole position detection component 31, and using the first hole position detection component 30 and the second hole position detection component 31 respectively for detecting holes or round holes on the top of the hood 12 and round holes on the upper side, the detection can accurately match the detection requirements of different types of holes. The inspector can quickly select the corresponding detection component according to the hole position type, avoiding the problems of inaccurate detection or inconvenience of operation that may occur due to the use of general-purpose inspection tools, further improving detection efficiency and accuracy, and thus improving the production efficiency and product quality of the automobile production line.

[0033] Furthermore, the first hole position detection component 30 includes a first hole position bracket 301 and a first hole position detection rod 302. The first hole position bracket 301 is mounted on the frame 10. The first hole position detection rod 302 is located at the top of the first hole position bracket 301, and the top of the first hole position detection rod 302 is provided with a first square protrusion 303 or a first circular protrusion 304 corresponding to a square hole or a round hole.

[0034] In this embodiment, the first hole position detection rod 302 is divided into two types: one is a first hole position detection rod 302 with a first square protrusion 303, which is used for detecting square holes; the other is a first hole position detection rod 302 with a first circular protrusion 304, which is used for detecting circular holes.

[0035] By setting a first hole position detection rod 302, and the top of the first hole position detection rod 302 is provided with a first square protrusion 303 or a first circular protrusion 304 corresponding to a square hole or a round hole, the first hole position detection rod 302 can accurately match the hole position on the hood 12. Compared with the existing handheld inspection tools that rely on manual judgment of hole size and position, the accuracy of inspection is greatly improved. During inspection, the first hole position detection rod 302 is simply inserted into the corresponding hole position, and the hole position can be quickly judged by observing the fit between the protrusion and the hole position. This reduces human error, improves inspection efficiency, and helps to detect problems with the holes of the hood 12 in a timely manner, ensuring the accuracy and quality of automobile assembly.

[0036] Furthermore, the second hole position detection component 31 includes a second hole position bracket 311 and a second hole position detection rod 312. The second hole position bracket 311 is mounted on the frame 10. The second hole position detection rod 312 is inclinedly mounted on the top of the second hole position bracket 311, and the top of the second hole position detection rod 312 has a first cylindrical protrusion 313 corresponding to the circular hole. By the second hole position detection rod 312 being inclinedly mounted on the top of the second hole position bracket 311, and having the first cylindrical protrusion 313 corresponding to the circular hole at its top, the detection rod can better adapt to the detection of the circular hole on the upper side of the hood 12. At the same time, the precise matching of the first cylindrical protrusion 313 with the circular hole ensures the accuracy of the detection, improves the detection efficiency, and reduces the detection error caused by improper detection angle or mismatch of the inspection tool, which is conducive to improving the production efficiency and product quality of the automobile production line.

[0037] Preferably, the slot detection assembly includes a first slot detection component 40, a second slot detection component 41, and a third slot detection component 43. The first slot detection component 40 is disposed inside the contour base 20 and is used for detecting slots on the upper part of the hood 12. The second slot detection component 41 is disposed inside the contour base 20 and is used for detecting circular slots on the hood 12. The third slot detection component 43 is disposed inside the contour base 20 and is used for detecting circular slots on the hood 12. By setting up a first slot detection component 40, a second slot detection component 41, and a third slot detection component 43, which are respectively used to detect the upper slot and the upper circular slot of the hood 12, the three components can perform specialized detection for different types of slots. Compared with the existing general handheld inspection tools, this method is more professional and accurate. Moreover, the inspectors can select the appropriate detection component according to the slot type to quickly and accurately complete the inspection task, improving inspection efficiency. At the same time, it ensures the accuracy of the inspection results for different types of slots, which helps to ensure that the quality of the slots on the hood 12 meets the requirements and improves the overall performance of the vehicle.

[0038] Furthermore, the first slot detection component 40 includes a first slot bracket 401 and a first slot detection rod 402. The first slot bracket 401 is located inside the contour base 20. The first slot detection rod 402 is located on the first slot bracket 401, and the first slot detection rod 402 is provided with a second square protrusion 403 corresponding to the square slot. By setting the first slot detection rod 402, and the top of the first slot detection rod 402 is provided with the second square protrusion 403 corresponding to the square slot, the first slot detection rod 402 can precisely match the square slot on the hood 12. During inspection, the first slot detection rod 402 only needs to be placed against the corresponding square slot, and the fit between the protrusion and the slot can be observed to quickly determine whether the hole position is qualified. This reduces human error, improves inspection efficiency, and helps to detect problems with the holes in the hood 12 in a timely manner, ensuring the accuracy and quality of automobile assembly.

[0039] Furthermore, the first slot bracket 401 is provided with a slide block 404, and the slide block 404 has a sliding groove 405. The first slot detection rod 402 is movably connected to the sliding groove 405, and a first locking nut 406 is provided between the first slot detection rod 402 and the slide block 404. By setting the slide block 404 and the sliding groove 405, and by movably connecting the first slot detection rod 402 to the sliding groove 405 and providing the first locking nut 406, this adjustable design allows the detection rod to be flexibly adjusted according to the square slots of different positions and sizes on the hood 12, improving the versatility and adaptability of the inspection tool.

[0040] Furthermore, the second slot detection component 41 includes a second slot support 411 and a second slot detection rod 412. The second slot support 411 is disposed inside the contour base 20. The second slot detection rod 412 is disposed on the second slot support 411, and the second slot detection rod 412 has a second circular protrusion 413 corresponding to the circular slot.

[0041] The third slot detection component 43 includes a third slot support 431 and a third slot detection rod 432. The third slot support 431 is located inside the contour base 20. The third slot detection rod 432 is mounted on the third slot support 431 and has a second cylindrical protrusion 433 corresponding to the circular slot.

[0042] By setting a second groove detection rod 412 with a second circular protrusion 413 corresponding to the circular groove, and setting a third groove detection rod 432 with a second cylindrical protrusion 433 corresponding to the circular groove, the second circular protrusion 413 and the second cylindrical protrusion 433 can precisely fit with the circular groove on the hood 12, improving the detection accuracy. At the same time, protrusions of different shapes can meet the detection needs of different types of circular grooves, making the detection more comprehensive and accurate, reducing errors in the detection process, improving detection efficiency, helping to ensure the quality of the circular groove on the hood 12, and improving the overall quality of the vehicle.

[0043] Preferably, the fixing component 50 includes a fixing bracket 51 and a fixing block 52. The fixing bracket 51 is mounted on the contour base 20, and the fixing block 52 is connected to the fixing bracket 51 via a connecting block 53. The fixing block 52 has a movable groove 521, and the fixing block 52 is connected to the connecting block 53 through the movable groove 521 via a second locking nut 54. The bottom surface detection rod 26 is located at the top of the fixing bracket 51 and is positioned opposite to the fixing block 52. By setting the fixing block 52 and the second locking nut 54, the inspector can adjust the position of the fixing block 52 according to the actual situation of the hood 12 and lock it to the connecting block 53 with the second locking nut 54, ensuring that the hood 12 is stably placed on the contour base 20. At the same time, the bottom surface detection rod 26 can accurately detect the bottom surface of the hood 12, improving the stability and accuracy of the detection, reducing the detection error caused by the unstable fixing of the hood 12, improving the detection efficiency, and ensuring the production quality of the automobile production line.

[0044] Preferably, the contour base 20 includes multiple sets of contour blocks 21 connected end to end. A movable rod 22 is connected to the outer side of each contour block 21 via a third locking nut 23. A rotating seat 27 is provided between the movable rod 22 and the frame 10, and a fourth locking nut 24 is provided between the movable rod 22 and the rotating seat 27. A limiting block 25 is provided on the side of the movable rod 22 away from the rotating seat 27. By setting up the contour blocks 21, movable rod 22, and rotating seat 27, the inspector can release the fourth locking nut 24 to lower the movable rod 22, and then release the third locking nut 23 to fix the contour blocks 21 and movable rod 22. This facilitates the replacement, maintenance, and upkeep of the contour blocks 21, improving their service life. Furthermore, by replacing different contour blocks 21, the inspection tool can be adapted to inspect the hood 12, thus enhancing its applicability.
