[0002] The fit of vehicle glass is a key indicator of its quality. Excessive or insufficient fit can cause deflection of the glass, leading to debonding, leakage, and other issues that affect the optical quality, appearance, and assembly, ultimately impacting the overall vehicle quality. The studs, as a crucial component of vehicle glass, significantly impact the fit. During vehicle glass inspection, a gauge is used to measure the deflection of the studs to determine if the fit is acceptable.

[0029] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0030] Existing nail stud detection fixtures take up too much space, have too many accessories, are inconvenient to use, and have low detection efficiency.

[0031] Based on this, please refer to Figures 1 to 7The utility model provides a positioning fixture, which is arranged on a work surface and is used to detect the offset of a nail column, comprising: a calibration seat 1, a detection component 2 and a sensing component 3. The calibration seat 1 is arranged on the work surface and is used to locate the reference position; the detection component 2 is slidably connected to the work surface and has a calibration end 211 and a positioning end 212. The detection component 2 can move relative to the reference position along the first direction and / or the second direction so that the calibration end 211 moves to correspond to the reference position, and / or the positioning end 212 moves to correspond to the nail column; the sensing component 3 is arranged on the work surface and is arranged corresponding to the calibration end 211, and is used to detect the distance between the calibration end 211 and the reference position in the first direction and / or the second direction. Specifically, the calibration end 211 is arranged corresponding to the reference position, which means that in the direction perpendicular to the reference position, the edge of the projection area of ​​the calibration end 211 coincides with the edge of the projection area of ​​the reference position. Taking the vertical arrangement of the positioning fixture as an example, the calibration end 211 is located directly above the reference position. Specifically, the sensing component 3 being disposed correspondingly to the calibration end 211 means that the sensing component 3 is disposed around the calibration end 211, with the reference position of the sensing component 3 serving as the initial zero position. In actual installation, the sensing component 3 is disposed opposite different sidewalls of the calibration end 211. During detection, the sensing component 3 is configured to detect the movement distance of the calibration end 211 relative to the reference position in the first direction or the second direction. Persons skilled in the art will be able to adjust the location of the sensing component 3 as needed, and this is not specifically limited.

[0032] Specifically, the first direction and the second direction are within the work surface and perpendicular to each other, and the third direction is perpendicular to the work surface. In actual use, the horizontal direction can be the first direction, the longitudinal direction can be the second direction, and the vertical direction can be the third direction. The work surface can be a testing surface or a placement surface.

[0033] It can be understood that the positioning inspection fixture provided by the present invention performs initial positioning of the detection component 2 through the calibration seat 1; after the initial positioning, when the positioning end 212 of the detection component 2 corresponds to the nail column, the calibration end 211 of the detection component 2 moves relative to the reference position along the first direction and / or the second direction, thereby generating a position offset. The sensing component 3 detects the offset of the calibration end 211 in the first direction and the second direction, and can obtain accurate nail column offset data. It is simple and convenient to use, the results are accurate, and the detection range is wide.

[0034] In some embodiments, the detection assembly 2 includes a connector 21 and a contoured positioning member 22. The contoured positioning member 22 is arranged along a third direction and disposed at a positioning end 212 of the connector 21. A calibration end 211 of the connector 21 is disposed corresponding to a reference position. The connector 21 is slidably connected to a work surface. The contoured positioning member 22 is disposed corresponding to the stud. During detection, the contoured positioning member 22 and the stud are aligned. The specific shape of the connector 21 can be adjusted based on the design modulus. When the stud does not deviate, the contoured positioning member 22 at the positioning end 212 is aligned with the stud, and the calibration end 211 is located directly above the reference position. The specific shape of the connector 21 can be adjusted by those skilled in the art based on different vehicle glass specifications, and is not specifically limited. If the stud deviates, the connector 21 is pushed, sliding the connector 21 on the work surface until the contoured positioning member 22 and the stud are aligned. At this point, the offset of the calibration end 211 from the reference position is the offset of the stud. This arrangement enables the operator to quickly locate the nail column, and the detection is convenient and accurate.

[0035] In some embodiments, the contoured positioning member 22 is provided with a receiving space 221 for receiving a nail post. Specifically, the contoured positioning member 22 is cylindrical in structure, allowing the nail post to enter the receiving space 221 during testing, making it easier for the contoured positioning member 22 to align with the nail post, reducing alignment difficulty and improving testing accuracy.

[0036] In some embodiments, the end of the profiling member 22 distal to the connecting plate is tapered toward the central axis of the profiling member 22. Specifically, the end of the profiling member 22 proximal to the stud has a tapered slope that gradually tapers toward the central axis. This configuration reduces the space occupied by the profiling member 22 proximal to the stud, preventing interference with other vehicle glass components. Furthermore, the slope facilitates the stud's entry into the accommodating space 221, facilitating a smoother inspection process.

[0037] In some embodiments, the apparatus further includes a sliding platform 23 disposed on a work surface, with the connector 21 disposed at the output end of the sliding platform 23. The output end of the sliding platform 23 is capable of sliding in a first direction and / or a second direction. In other words, the sliding platform 23 enables the connector 21 to slide horizontally or vertically, ensuring a stable and reliable sliding process. The installation of the sliding platform 23 facilitates operator replacement of the connector 21, thereby enhancing the adaptability of the positioning fixture.

[0038] In some embodiments, the calibration base 1 is provided with a positioning hole 11 in the thickness direction of the calibration base 1;

[0039] The calibration end 211 is provided with a first through hole 213 extending through the thickness of the connector 21. The first through hole 213 corresponds to the positioning hole 11. After the first through hole 213 and the positioning hole 11 are provided, calibration can be performed by aligning the first through hole 213 with the positioning hole 11 during calibration, thereby completing calibration and positioning of the reference position. This provides ease of operation and high reliability.

[0040] In some embodiments, a calibration pin 24 is further included, extending through the first through-hole 213 and into the positioning hole 11. The calibration pin 24 allows for direct calibration of the reference position by simply plugging and unplugging the pin. This simplifies operation while ensuring calibration accuracy, thereby ensuring the accuracy of the final offset detection.

[0041] Preferably, in a direction perpendicular to the work surface, the projection area of ​​the positioning hole 11 is within the projection area of ​​the first through hole 213. That is, the first through hole 213 is slightly larger than the positioning hole 11, and the calibration pin 24 is correspondingly configured in a stepped shape. This configuration facilitates insertion of the calibration pin 24 into the first through hole 213, improving operational simplicity, while also preventing shaking during calibration and improving calibration accuracy.

[0042] Preferably, the portion where the calibration pin 24 contacts the positioning hole 11 is provided with an exhaust groove to facilitate exhausting the air in the positioning hole 11 and prevent the air from obstructing the calibration pin 24 from entering the positioning hole 11 .

[0043] In some embodiments, the sensing component 3 includes a sensing probe 31, which is arranged on the extension line of the first direction and the second direction of the center of the calibration seat 1. Two groups of sensing probes 31 are provided to detect the distance from the calibration end 211 in the first direction or the second direction respectively. After the connecting member 21 slides, the distance changes, and the amount of change is the offset. With this arrangement, the overall detection accuracy is high, and the offset of the nail column can be accurately represented by the change in distance in two directions. There is no need to limit the displacement direction of the connecting member 21, and the positioning fixture has strong adaptability. Specifically, the sensing probe 31 can use different types of displacement sensors, such as contact linear displacement sensors, or non-contact photoelectric displacement sensors, magnetic displacement sensors, etc. Those skilled in the art can select a suitable sensing probe 31 according to actual needs without specific limitation.

[0044] In some embodiments, the sensing probe 31 includes a telescopic detection portion 311 that can maintain contact with the calibration end 211. Specifically, the sensing probe 31 utilizes a linear displacement sensor. During the detection process, the telescopic detection portion 311 maintains contact with the sidewall of the calibration end 211. When the calibration end 211 moves, the amount of telescopic detection portion 311 changes, and this change in telescopic detection portion 311 is referred to as the offset. This configuration offers a simple structure and reliable detection capabilities. It also facilitates alignment of the sensing probe 31 with the calibration end 211, improving detection accuracy.

[0045] In some embodiments, a control component is further included, which is electrically connected to the sensing component 3. Specifically, the sensing component 3 transmits the detected offset signal to the control component, which can be directly displayed or used for subsequent calculations, and has a high degree of intelligence.

[0046] Please refer to Figures 1 to 7 The first embodiment of the present invention is a positioning fixture, which is arranged on a work surface and is used to detect the offset of a nail column, comprising:

[0047] Calibration seat 1, set on the work surface, used for locating the reference position;

[0048] The detection assembly 2 is slidably connected to the work surface and has a calibration end 211 and a positioning end 212. The detection assembly 2 can move in a first direction and / or a second direction relative to the reference position so that the calibration end 211 moves to correspond to the reference position and / or the positioning end 212 moves to correspond to the nail post;

[0049] The sensing component 3 is disposed on the work surface and corresponds to the calibration end 211 , and is used to detect the distance between the calibration end 211 and the reference position in the first direction or the second direction.

[0050] The detection component 2 includes a connecting member 21 and a contour positioning member 22. The contour positioning member 22 is distributed along the third direction and is arranged at the positioning end 212 of the connecting member 21. The calibration end 211 of the connecting member 21 is arranged corresponding to the reference position. The connecting member 21 is slidably connected to the work surface.

[0051] The sliding platform 23 is provided on the work surface, and the connecting member 21 is provided at the output end of the sliding platform 23 . The output end of the sliding platform 23 can slide along the first direction and / or the second direction.

[0052] In the thickness direction of the calibration seat 1, the calibration seat 1 is provided with a positioning hole 11;

[0053] In the thickness direction of the connecting member 21 , the calibration end 211 is provided with a first through hole 213 penetrating the thickness direction of the connecting member 21 . The first through hole 213 is provided corresponding to the positioning hole 11 .

[0054] The device further includes a calibration pin 24 , which passes through the first through hole 213 and extends into the positioning hole 11 .

[0055] In this embodiment, the end of the contoured positioning member 22 away from the connecting plate is retracted inwardly in a direction gradually approaching the central axis of the contoured positioning member 22 .

[0056] In this embodiment, an accommodating space 221 is defined in the contoured positioning member 22 , and the accommodating space 221 is used to accommodate a nail post.

[0057] The working principle of the present invention is as follows: when in use, the positioning fixture is placed under the vehicle glass, and the calibration seat 1 is aligned with the vehicle glass according to the designed position. Before starting the test, the calibration pin 24 is passed through the first through hole 213 and inserted into the positioning hole 11 to complete the positioning of the connector 21 and the calibration seat 1. If the nail column has no offset, the nail column is directly accommodated in the accommodating space 221 of the contoured positioning member 22. If the nail column is offset, push the connector 21 or the contoured positioning member 22 to slide the output end of the sliding table 23 in the horizontal or vertical direction until the nail column is accommodated in the accommodating space 221 of the contoured positioning member 22, completing the positioning of the nail column. At this time, the sensing component 3 detects the change in the distance between the calibration end 211 and the reference position in the first direction and the second direction, and obtains the offset of the nail column.
