Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, and in particular to a testing tool for automotive sunroof glass. Background Technology

[0002] As an important component of the car body, the sunroof glass, installed on the roof, not only effectively promotes air circulation and enhances driving comfort, but also provides a wide field of vision and meets the needs of mobile photography and videography, making it an indispensable feature in modern automotive design. To ensure the precision and sealing of the sunroof glass during assembly and avoid problems such as leakage, abnormal noise, or operational stagnation caused by dimensional deviations or deformation, its key geometric parameters must be rigorously inspected before production or assembly. Therefore, specialized inspection tools play a crucial role in automotive manufacturing quality control. As a key inspection method, their inspection capabilities and flexibility have a decisive impact on the overall vehicle assembly quality and production efficiency. Especially in the core process of inspecting the dimensions, contours, and mounting hole positions of the sunroof glass, existing inspection tools have gradually revealed a series of obvious limitations and technical problems when handling sunroof glass of different models, curvatures, or specifications.

[0003] Chinese utility model patent CN201921567085.6 discloses an automotive sunroof glass inspection tool. Although this device achieves the adjustment of the position of the inspection piece through movable first and second mounting plates and drive components, and has a certain range of adaptability, it can meet the positioning and inspection needs of sunroof glass of different sizes to a certain extent and save the cost of multiple sets of inspection tools. However, its structure still has obvious shortcomings: the inspection tool can only adjust the position of the inspection piece in a horizontal plane and cannot realize the angle flipping or tilting adjustment of the sunroof glass itself. As a result, the glass is always in a fixed posture during the inspection process, making it difficult to conduct all-round and multi-angle inspection of the edge sealing area, inclined curved surface or top arc surface. Especially for panoramic sunroof glass with complex curved surface or irregular structure, the inspection blind spot is obvious and it is impossible to fully evaluate its matching status with the vehicle body.

[0004] Therefore, to address the shortcomings of existing technologies, we urgently need a new inspection tool for automotive sunroof glass to solve this problem. This new tool should significantly improve the comprehensiveness and flexibility of the inspection, enabling precise positioning and attitude adjustment of the sunroof glass in multiple degrees of freedom, while better meeting the needs of modern automobile manufacturing for efficient, accurate, and omnidirectional inspection, providing strong support for the continuous improvement of automobile assembly quality. Utility Model Content

[0005] The purpose of this invention is to provide a testing tool for automotive sunroof glass, which solves the problem that existing testing tools can only adjust the position of the test piece in a horizontal plane, and cannot achieve the angle flipping or tilting adjustment of the sunroof glass itself, resulting in the glass always being in a fixed posture during the testing process, making it difficult to conduct all-round and multi-angle inspection of the edge sealing area, inclined curved surface or top arc surface.

[0006] To achieve the above objectives, this utility model provides a tool for inspecting automotive sunroof glass, including a support base and a support plate. The support plate is disposed on the top of the support base and is rotatably connected to the top of the support base via a rotating base. Vertical plates are fixedly connected to both sides of the top of the support plate, and a support bracket is provided between the two vertical plates.

[0007] Both of the two support brackets are rotatably connected to the upright plate on opposite sides, and a drive structure for driving the support brackets to rotate is installed on the side wall of one side of the upright plate.

[0008] The support frame has sliding grooves on both sides of the top, and a sliding block is slidably connected inside each sliding groove. The top of the sliding block is provided with an adsorption cover, and one side is provided with a positioning structure that can be detachably connected to the side wall of the support frame. The bottom of the support frame is provided with a connecting pipe and a connecting tube. The two ends of the connecting pipe pass through the two sliding blocks and are connected to the adsorption cover, respectively. One end of the connecting tube is connected to the connecting pipe, and the other end is connected to the exhaust device.

[0009] A pressure plate is provided at the top center of the support frame, and the pressure plate is connected to the support frame through a vertical lifting structure.

[0010] The support frame has an inner wall connected to a mounting plate on one side, and the vertical lifting structure includes a lifting cylinder installed at the bottom of the mounting plate. The output end of the lifting cylinder is connected to the bottom of the pressure plate.

[0011] The drive structure includes a drive motor mounted on the top of one side of the upright plate, and the output shaft of the drive motor is connected to an adjacent support frame.

[0012] The pressure plate is made of metal, and a flexible pad is fixedly connected to the bottom of the pressure plate.

[0013] The positioning structure includes a positioning plate disposed on one side of the support frame. A horizontal plate is fixedly connected to the bottom end of the positioning plate. One end of the horizontal plate is connected to the side wall of the sliding block. A positioning screw with one end threaded through the positioning plate is provided on one side of the positioning plate. Several positioning holes adapted to the positioning screw are provided on both sides of the support frame.

[0014] The support base has an installation groove on its top that is compatible with the rotating base, and both upright plates have through grooves on one side of their bottom for connecting pipes to pass through.

[0015] This utility model discloses a testing fixture for automotive sunroof glass. A rotating base connects a support plate to a support seat, enabling the support plate to rotate freely in the horizontal plane. This allows for circumferential angle adjustment of the sunroof glass, solving the problem of traditional fixtures being unable to change the glass's orientation and facilitating inspection from multiple directions. The support frame and upright plate are rotatably connected and controlled by a drive structure to tilt or flip the sunroof glass in the vertical plane, effectively exposing the edge sealing area, top curved surface, and tilted curved surface, eliminating blind spots. This is particularly suitable for omnidirectional inspection of complex curved glass surfaces such as panoramic sunroofs. Inspection: The adsorption hood is connected to the exhaust equipment via connecting pipes and connecting tubes. Under negative pressure, it reliably adsorbs and fixes the glass edge, avoiding damage to the glass surface and ensuring stability without falling off at multiple angles. The sliding block slides in the sliding groove, allowing the adsorption hood to be adjusted laterally to fit different sizes of skylight glass. Combined with the detachable positioning structure, it enables quick locking, improving the versatility and adjustment flexibility of the inspection tool. The pressure plate simulates vertical loading through a vertical lifting structure, which can detect the deformation and matching accuracy of the glass under assembly stress, more realistically reflecting the actual installation situation.

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] Example 1

[0025] Please see Figure 1-5 As shown, a testing tool for inspecting car sunroof glass in this embodiment includes a support base 1 and a support plate 4. The support plate 4 is disposed on the top of the support base 1 and is rotatably connected to the top of the support base 1 through a rotating base 5. Upright plates 2 are fixedly connected to both sides of the top of the support plate 4, and a support bracket 3 is provided between the two upright plates 2.

[0026] The two support brackets 3 are rotatably connected to the upright plate 2 on opposite sides, and a drive structure for driving the support brackets 3 to rotate is installed on the side wall of one side of the upright plate 2.

[0027] The top two sides of the support frame 3 are provided with sliding grooves 11, and each sliding groove 11 is slidably connected with a sliding block 14. The top of the sliding block 14 is provided with an adsorption cover 17, and one side is provided with a positioning structure that can be detachably connected to the side wall of the support frame 3. The bottom of the support frame 3 is provided with a connecting pipe 7 and a connecting pipe 6. The two ends of the connecting pipe 7 pass through the two sliding blocks 14 and are connected to the adsorption cover 17, respectively. One end of the connecting pipe 6 is connected to the connecting pipe 7, and the other end is connected to the exhaust device.

[0028] A pressure plate 8 is provided at the top center of the support frame 3, and the pressure plate 8 is connected to the support frame 3 through a vertical lifting structure.

[0029] Workflow: When using this inspection tool for automotive sunroof glass, first place the sunroof glass to be inspected on two support brackets 3. The support brackets 3 are positioned between the upright plates 2 on both sides of the top of the support plate 4, and the support brackets 3 and the upright plates 2 are rotatably connected. The drive structure on one side of the upright plate 2 can control the support bracket 3 to rotate around the connecting shaft, thereby causing the sunroof glass to tilt or flip at a certain angle. The support plate 4 is rotatably connected to the support base 1 below through the rotating base 5, so that the entire support plate 4 can rotate along the horizontal plane, thereby causing the sunroof glass to adjust its circumferential angle, realizing multi-angle and multi-directional inspection posture adjustment. After the glass is placed in place, start the exhaust device connected to the connecting pipe 6. The exhaust device is connected to the connecting pipe 7 through the connecting pipe 6. The connecting pipe 7 passes through two sliding blocks 14 and is connected to the suction cover 17 on the top of the sliding blocks 14 on both sides respectively, forming... The negative pressure channel allows the adsorption hood 17 to adhere to and fix the edge of the sunroof glass under negative pressure, ensuring its stability and preventing slippage during flipping or movement. The sliding block 14 can slide left and right within the sliding groove 11 on the top of the support frame 3, thereby adjusting the distance between the two adsorption hoods 17 to accommodate sunroof glass of different widths. After adjustment, the sliding block 14 is locked to the side wall of the support frame 3 by the positioning structure to prevent displacement during the inspection process. Then, the vertical lifting structure is activated, driving the pressure plate 8 to press down vertically from the top center of the support frame 3, simulating the vehicle body installation state to apply a preset pressure to the glass, and detecting its deformation under stress or the matching accuracy with the sealing structure. Under different angles and stress states, the operator can comprehensively inspect the contour, edge gap, mounting hole position, and curved surface fit of the sunroof glass, completing multi-angle and omnidirectional inspection.

[0030] Example 2

[0031] Please see Figure 1-5 As shown in the figure, this embodiment of a testing fixture for automotive sunroof glass includes a mounting plate 13 connected to one side of the inner wall of a support bracket 3. The vertical lifting structure includes a lifting cylinder 12 installed at the bottom of the mounting plate 13. The output end of the lifting cylinder 12 is connected to the bottom of a pressure plate 8. Specifically, through the cooperation between the mounting plate 13 connected to one side of the inner wall of the support bracket 3 and the lifting cylinder 12, the lifting cylinder 12 is installed at the bottom of the mounting plate 13, and its output end is connected to the bottom of the pressure plate 8. When the lifting cylinder 12 is activated during testing, it can push the pressure plate 8 to press down smoothly in the vertical direction, thereby simulating loading on the sunroof glass and achieving the effects of providing stable vertical pressure, accurately detecting glass deformation under stress, and improving assembly matching accuracy.

[0032] The pressure plate 8 is made of metal, and a flexible pad is fixedly connected to the bottom of the pressure plate 8. Specifically, by making the pressure plate 8 of metal and fixing the flexible pad to its bottom, the metal material ensures the structural strength and rigidity during the pressing process of the pressure plate 8, while the flexible pad contacts the surface of the sunroof glass, playing a buffering and protective role, preventing hard contact from causing scratches on the glass or local stress concentration, thus achieving the effect of ensuring uniform force application while avoiding damage to the surface of the glass being inspected.

[0033] Example 3

[0034] Please see Figure 1-5 As shown in the figure, this embodiment of a tool for inspecting automotive sunroof glass includes a drive structure comprising a drive motor 9 mounted on the top of one side of a vertical plate 2. The output shaft of the drive motor 9 is connected to an adjacent support frame 3. Specifically, by mounting the drive motor 9 on the top of one side of the vertical plate 2 and connecting its output shaft to the adjacent support frame 3, the rotation angle and speed of the support frame 3 can be precisely controlled after the drive motor 9 is started, thereby automating the tilting or flipping action of the sunroof glass. This avoids the instability caused by manual flipping and achieves the effects of improving flipping accuracy, ease of operation, and consistency of inspection.

[0035] The positioning structure includes a positioning plate 16 disposed on one side of the support frame 3. A horizontal plate is fixedly connected to the bottom end of the positioning plate 16. One end of the horizontal plate is connected to the side wall of the sliding block 14. A positioning screw 15 with one end threaded through the positioning plate 16 is provided on one side of the positioning plate 16. Several positioning holes 10 adapted to the positioning screw 15 are provided on both sides of the support frame 3. Specifically, the positioning plate 16 included in the positioning structure is disposed on one side of the support frame 3. The horizontal plate connected to the bottom end of the positioning plate 16 is connected to the side wall of the sliding block 14. A positioning screw 15 is provided on one side of the positioning plate 16. One end of the screw 15 is threaded through the positioning plate 16 and inserted into any one of the several positioning holes 10 opened on the side wall of the support frame 3. When the sliding block 14 is adjusted to the required position, the positioning screw 15 is rotated to make it embed into the corresponding positioning hole 10, thereby achieving the effect of quickly locking the position of the sliding block 14, flexibly adjusting and firmly connecting.

[0036] The top of the support base 1 is provided with an installation groove 18 that is compatible with the rotating base 5. The bottom of one side of each of the two upright plates 2 is provided with a through groove 19 for the connecting pipe 6 to pass through. Specifically, by matching the installation groove 18 on the top of the support base 1 with the rotating base 5, the precise positioning and stable installation of the rotating base 5 are achieved, ensuring the coaxiality and stability of the support plate 4 in the horizontal plane. At the same time, the through groove 19 on one side of the bottom of the two upright plates 2 allows the connecting pipe 6 to pass through, preventing the pipe from being squeezed or twisted when the support frame 3 rotates, ensuring the smooth flow of the negative pressure air circuit, and achieving the effect of improving the assembly accuracy of the structure, ensuring the stable operation of the air circuit system and the overall reliability of the equipment.

[0037] When using this inspection tool for automotive sunroof glass, first place the support base 1 in the work area. The support plate 4 is installed in the mounting groove 18 on the top of the support base 1 via a rotating base 5, allowing free rotation in the horizontal plane. Vertical plates 2 are fixedly connected to both sides of the top of the support plate 4. A support frame 3 is provided between the two vertical plates 2. One side of the support frame 3 is rotatably connected to the vertical plate 2, and the other side is driven by a drive motor 9 installed on the top of one side of the vertical plate 2. Its output shaft is connected to the support frame 3, allowing control of the support frame 3 to tilt or flip around the connecting shaft. The sunroof glass to be inspected is placed... After being placed on the two support brackets 3, the external exhaust device connected to the connecting pipe 6 is activated. The exhaust device is connected to the connecting pipe 7 at the bottom of the support bracket 3 through the connecting pipe 6. The connecting pipe 7 passes through the support bracket 3 and is connected to the adsorption cover 17 on the top of the sliding blocks 14 on both sides respectively. Under the action of negative pressure, the glass edge is adsorbed and fixed, ensuring that it does not shift during the posture adjustment process. The sliding block 14 can slide left and right in the sliding groove 11 opened on the top of the support bracket 3 to adjust the distance between the two adsorption covers 17 to adapt to skylight glass of different widths. After adjustment, the positioning structure is used to fix the glass. The locking mechanism includes a positioning plate 16 on one side of the support frame 3, with its bottom end connected to a horizontal plate and fixed to the side wall of the sliding block 14. The positioning plate 16 has a positioning screw 15. Rotating the screw causes one end to thread through and embed into any one of the several positioning holes 10 opened in the side wall of the support frame 3, thus achieving a stable and limited position of the sliding block 14. Simultaneously, the connecting pipe 6 passes through a through groove 19 opened at the bottom of the vertical plate 2, preventing pipe compression or twisting during the rotation of the support frame 3 and ensuring unobstructed airflow. Subsequently, the vertical lifting structure is activated to apply a simulated pressure to the glass. The pressure distribution structure includes a lifting cylinder 12 mounted on a mounting plate 13 on one side of the inner wall of the support bracket 3. Its output end is connected to the bottom of the pressure plate 8, pushing the pressure plate 8 to press down vertically. The pressure plate 8 is made of metal to ensure strength and rigidity, and a flexible pad is fixedly connected to its bottom to avoid damage to the glass surface. With the multiple effects of the rotatable support plate 4, the flip-up support bracket 3, reliable adsorption and fixation, and realistic pressing, the operator can comprehensively inspect the contour, edge gap, mounting hole position and curved surface fit of the sunroof glass under different angles and stress conditions. The device achieves circumferential rotation of the support plate 4 in the horizontal direction through the cooperation of the rotating base 5 and the mounting groove 18, facilitating inspection from multiple angles; the drive motor 9 drives the support bracket 3 to automatically flip, allowing the sunroof glass to tilt in the vertical plane, effectively exposing the top arc surface and edge sealing area, eliminating blind spots in inspection; the adsorption cover 17 achieves non-contact fixation through the negative pressure system formed by the connecting pipe 7 and the connecting pipe 6, avoiding clamping damage; the sliding block 14 slides in the sliding groove 11 and is locked by the positioning screw 15 and the positioning hole 10, achieving quick adaptation and stable connection; the lifting cylinder 12 drives the pressure plate 8 to apply precise pressure, the metal material ensures structural stability, and the flexible pad protects the glass surface; the through groove 19 ensures that the connecting pipe 6 is not obstructed during movement.
