Description

Technical Field

[0001] This utility model relates to the field of automotive sunroof brackets, and in particular to an automotive sunroof bracket inspection tool. Background Technology

[0002] In the automotive manufacturing industry, the sunroof bracket, as a crucial structural component connecting the car's roof and sunroof assembly, directly affects the sunroof's sealing performance, opening smoothness, and overall vehicle aesthetics due to its dimensional accuracy, assembly position, and angle. Therefore, precise and efficient testing of the sunroof bracket during production is a key step in ensuring product quality.

[0003] However, most sunroof bracket inspection fixtures currently used in the industry are fixed structures. These fixtures are usually custom-designed for specific models or size ranges of sunroof brackets. Their clamping and positioning structures and inspection reference surfaces are fixed after manufacturing. However, the width of sunroof brackets may vary between different car models or different configurations of the same car model. This means that when it is necessary to inspect sunroof brackets with different widths, either a separate special fixture must be provided for each width specification, resulting in a wide variety of fixtures, or the sunroof brackets may need to meet the accuracy requirements of multiple angles during actual assembly. However, existing fixed fixtures can often only be inspected at a single or limited number of preset angles. The lack of multi-angle and all-round inspection capabilities not only increases the complexity of operation, but also limits the fixture's ability to comprehensively evaluate the overall assembly status of the sunroof bracket. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automotive sunroof bracket inspection tool. Through a limiting component, the tool allows users to make corresponding adjustments according to the width of different brackets, enabling it to quickly adapt to the inspection needs of sunroof brackets of different specifications.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a car sunroof bracket inspection tool, comprising a housing, a rotating rod rotatably connected to the top of the inner wall of the housing, a horizontal plate fixedly connected to the outer wall of the rotating rod, rotating columns rotatably connected to the left and right sides of the inner wall of the horizontal plate, a first gear fixedly connected to the outer wall of the rotating column, toothed plates meshing with the left and right sides of the outer wall of the first gear, a connecting column fixedly connected to the top of the toothed plate, a first clamp fixedly connected to the top of the connecting column on the left end, an inner tube fixedly connected to the outer wall of the first clamp, a limiting component provided inside the inner tube, and the inner tube limiting the first clamp through the limiting component.

[0006] Furthermore, the limiting component includes a compression spring fixedly connected to the inner wall of the inner tube, a pressure ring fixedly connected to the bottom end of the compression spring, a retaining element fixedly connected to the inner wall of the pressure ring, and the outer wall of the retaining element slidably connected to the inner wall of the inner tube.

[0007] Furthermore, the top of the horizontal plate is provided with several slots, the size of which is adapted to the size of the card, and the card is used to engage with the slots.

[0008] Furthermore, a second clamp is fixedly connected to the top of the connecting column on the right end. The first clamp and the second clamp slide on the top of the inner wall of the horizontal plate through the connecting column. A clamping plate is slidably connected to the inner wall of both the first clamp and the second clamp. The clamping plate is used to squeeze the top of the bracket.

[0009] Furthermore, the inner wall of the clamping plate is threadedly connected to a threaded rod, and the outer wall of the threaded rod rotates within the inner walls of the first and second clamps.

[0010] Furthermore, a second gear is fixedly connected to the rear end of the outer wall of the rotating rod, a third gear is meshed with the bottom end of the outer wall of the second gear, a turntable is fixedly connected to the inner wall of the third gear, a round tube is fixedly connected to the rear end of the outer wall of the turntable, an insert rod is slidably connected to the rear end of the inner wall of the round tube, and the front end of the insert rod is engaged at the rear end of the housing.

[0011] Furthermore, a tension spring is fixedly connected to the inner wall of the circular tube, and a plug rod is fixedly connected to the rear end of the tension spring. Several slots are provided at the rear end of the outer wall of the box, and the size of the slots is adapted to the plug rod.

[0012] This utility model has the following beneficial effects:

[0013] 1. In this utility model, the limiting component allows the user to make corresponding adjustments according to the width of different brackets, no longer limited to a single specification of sunroof bracket, and can quickly adapt to the testing needs of various width specifications of sunroof brackets on the market.

[0014] 2. In this utility model, by pulling out the insert rod and disengaging it from the slot, the restriction on the turntable is released. Then, the turntable is rotated to drive the third gear to rotate, which in turn drives the second gear and the rotating rod on it to rotate. This causes the rotating rod to carry the inspection tool to change angles, thereby achieving precise inspection of sunroof brackets at different installation angles, significantly improving inspection efficiency and accuracy.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-3This utility model provides an embodiment of a car sunroof bracket inspection tool, comprising a housing 1, a rotating rod 18 rotatably connected to the top of the inner wall of the housing 1, a horizontal plate 2 fixedly connected to the outer wall of the rotating rod 18, rotating columns 16 rotatably connected to the left and right sides of the inner wall of the horizontal plate 2, a first gear 15 fixedly connected to the outer wall of the rotating column 16, toothed plates 14 meshing with the left and right sides of the outer wall of the first gear 15, a connecting column 17 fixedly connected to the top of the toothed plate 14, a first clamp 3 fixedly connected to the top of the left end of the connecting column 17, an inner tube 7 fixedly connected to the outer wall of the first clamp 3, and a limit assembly provided inside the inner tube 7, the limit assembly including a compression spring 20 fixedly connected to the inner wall of the inner tube 7, the bottom end of the compression spring 20 being fixedly connected to... A pressure ring 21 is connected, and a clamp 8 is fixedly connected to the inner wall of the pressure ring 21. The outer wall of the clamp 8 is slidably connected to the inner wall of the inner tube 7. Several slots 9 are opened at the top of the horizontal plate 2. The size of the slots 9 is adapted to the clamp 8. The clamp 8 is used to be inserted into the slots 9. A second clamp 4 is fixedly connected to the top of the right end connecting column 17. The first clamp 3 and the second clamp 4 slide on the top of the inner wall of the horizontal plate 2 through the connecting column 17. The inner walls of the first clamp 3 and the second clamp 4 are slidably connected to a clamping plate 6. The clamping plate 6 is used to squeeze the top of the bracket. The inner wall of the clamping plate 6 is threadedly connected to a threaded rod 5. The outer wall of the threaded rod 5 rotates in the inner wall of the first clamp 3 and the second clamp 4. The inner tube 7 limits the first clamp 3 through a limiting component.

[0023] Specifically, the user needs to pull the locking piece 8 upwards. As the locking piece 8 rises, it drives the pressure ring 21 fixed on it to move together, causing the pressure ring 21 to apply a downward squeezing force to the compression spring 20. At the same time, the locking piece 8 disengages from the horizontal plate 2, releasing the axial restriction on the first clamp 3 and giving it the freedom to move back and forth. Next, the operator can push the first clamp 3 forward, causing the connecting post 17 connected to its bottom end to slide forward on the guide rail or plane of the horizontal plate 2. The forward movement of the connecting post 17 causes the toothed plate 14 at its bottom end to move forward along the preset track, causing the toothed plate 14 to push the first gear 15 to rotate. The rotation of the first gear 15 will in turn drive the right toothed plate 14 in the opposite direction. Then, the backward movement of the right toothed plate 14 will cause the connecting post 17 at its top to move backward, causing the connecting post 17 to move the second clamp 4 backward, thus moving the first clamp... The first clamp 3 is pushed forward, while the second clamp 4 is pulled backward. The distance between the two is quickly and precisely adjusted until the space between them can just accommodate the width of the sunroof bracket to be tested. After the width adjustment is completed, the threaded rod 5 is rotated. The rotation of the threaded rod 5 will drive the clamping plate 6 that it cooperates with to move. The clamping plate 6 will apply a downward squeezing force to the top of the sunroof bracket that is placed between the first clamp 3 and the second clamp 4 and is co-positioned, ensuring the stability of the bracket in the vertical direction. Finally, when the user releases the clamp 8 that was initially pulled up, the previously compressed spring 20 will quickly rebound. Under the elastic force of the spring 20, the clamp 8 is forcefully pushed back to its original position and re-inserted into the slot on the horizontal plate 2. This action re-locks the position of the first clamp 3, fixing it at the distance adjusted for the current width of the bracket. At this point, the fit test can begin.

[0024] Reference Figure 2 and Figure 4 A second gear 19 is fixedly connected to the rear end of the outer wall of the rotating rod 18. A third gear 22 is meshed with the bottom end of the outer wall of the second gear 19. A turntable 10 is fixedly connected to the inner wall of the third gear 22. A round tube 11 is fixedly connected to the rear end of the outer wall of the turntable 10. An insert rod 12 is slidably connected to the rear end of the inner wall of the round tube 11. The front end of the insert rod 12 is locked at the rear end of the box body 1. A tension spring 23 is fixedly connected to the inner wall of the round tube 11. The insert rod 12 is fixedly connected to the rear end of the tension spring 23. Several slots 13 are opened at the rear end of the outer wall of the box body 1. The size of the slots 13 is adapted to the insert rod 12.

[0025] Specifically, by pulling the insert rod 12 outward, it is completely disengaged from the inner side of the housing 1, thus releasing the radial restriction of the turntable 10 and allowing it to rotate. Then, the operator can directly hold and rotate the turntable 10, causing it to directly drive the third gear 22 to rotate as well. When the third gear 22 rotates, it drives the second gear 19 to rotate in the opposite direction, causing the rotation of the second gear 19 to drive the rotating rod 18 to rotate. The rotating rod 18 rotates synchronously with the horizontal plate 2 on its outer wall. The sunroof bracket, which has already been width-positioned, is firmly clamped on the horizontal plate 2. Finally, the entire horizontal plate 2, together with the bracket clamped on it, can rotate flexibly around the central axis of the rotating rod 18. This allows the operator to easily adjust the bracket to any required detection angle, meeting the requirements of multi-angle detection.

[0026] Working principle: By pulling the clamp 8 upward, the clamp 8, along with the pressure ring 21, squeezes the pressure spring 20, causing the clamp 8 to leave the horizontal plate 2 and release the restriction on the first clamp 3. Then, the first clamp 3 is pushed forward, causing the first clamp 3, along with the connecting column 17, to move forward on the horizontal plate 2. The connecting column 17 drives the corresponding toothed plate 14 at the bottom to move forward. Then, through the forward movement of the toothed plate 14, the toothed plate 14 drives the first gear 15 to rotate, causing the first gear 15 to push the right toothed plate 14 backward, carrying the connecting column 17. The right connecting column 17 then carries the top second clamp 4 backward until the sunroof bracket can be placed between the first clamp 3 and the second clamp 4. Then, the threaded rod 5 is rotated, causing the threaded rod 5 to push the clamp 6 to squeeze the top of the bracket placed on the first clamp 3 and the second clamp 4. Then, the clamp 6 is released, causing the pressure spring 20 to rebound and insert the clamp 8 back onto the horizontal plate 2, and the testing can begin.

[0027] When angle detection is required, the plug rod 12 is pulled outward to detach it from the housing 1 and release the restriction on the turntable 10. Then, the turntable 10 is rotated, causing the third gear 22 to rotate. The third gear 22 drives the second gear 19 to rotate, causing the second gear 19 to rotate the rotating rod 18 and the horizontal plate 2 on the outer wall of the rotating rod 18. The horizontal plate 2 then rotates the angle of the clamped bracket.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
