Description

Technical Field

[0001] This utility model belongs to the field of automotive windshield lower trim panels, specifically, it relates to a detection device for automotive windshield lower trim panels. Background Technology

[0002] The lower windshield trim panel is an important functional component located below the windshield of a car. It serves multiple purposes, including waterproofing, airflow diversion, protection, and decoration. Aging or damage to the trim panel can affect vehicle safety. It is used to cover the gap between the bottom of the windshield and the engine compartment, concealing structural components and wiring, and enhancing the integrity and aesthetics of the front of the vehicle. It also prevents rainwater, dust, fallen leaves, and other foreign objects from directly entering the engine compartment, avoiding moisture, blockage, or damage to internal components. Some models are equipped with sealing strips to further enhance waterproofing and dustproofing.

[0003] Currently, the industry generally uses coordinate measuring machine (CMM) for detecting deformation of the lower windshield trim panel. However, CMM is relatively complex to operate and slow, which cannot meet the need for quickly identifying deformation of the lower windshield trim panel and providing data quickly. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a vehicle front windshield lower decorative panel testing device, comprising a workbench, a testing mechanism installed on the workbench, and a product disposed on the testing mechanism;

[0006] The testing mechanism includes a high support platform installed on the rear side of the top of the workbench, a low support platform installed on the front side of the top of the workbench, and side support platforms installed on both sides of the workbench. The top of the high support platform, the low support platform, and the side support platforms are respectively provided with some components of the contour block.

[0007] Preferably, several sets of horizontal tilting mechanisms are evenly arranged on the high support platform, and each set of horizontal tilting mechanisms is equipped with a dial indicator at its front end.

[0008] Preferably, the low support platform is arranged with several sets of bases, and each set of bases is provided with a detection shaft that is adapted to it.

[0009] Preferably, a side dial indicator is provided on the side of each of the two sets of side support platforms that are separated from each other.

[0010] The beneficial effects of adopting the above technical solutions are:

[0011] I. This utility model adopts a dedicated contour positioning and multi-point synchronous detection design, which is simple to operate. After placing the product on it, multiple tests can be completed quickly, and the time required is much lower than that of coordinate measuring machine, which greatly improves the efficiency of online detection. Compared with expensive coordinate measuring machines, this device has lower manufacturing and maintenance costs and is more suitable for large-scale deployment on production lines.

[0012] Second, by directly reading the specific values ​​of the deformation variables through a dial gauge, precise and quantitative data support is provided for analyzing the causes of deformation and adjusting the production process, avoiding errors caused by human judgment; the contour blocks can be replaced according to the decorative panels of different car models, giving the device a certain degree of versatility; the entire device has a stable structure, good repeatability, and small deviation, ensuring the reliability of the test results.

[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of this utility model, and to facilitate its implementation.

[0022] Specifically, such as Figures 1 to 6 As shown, a vehicle windshield trim panel testing device includes a workbench 1, a testing mechanism 2 mounted on the workbench 1, and a product 3 disposed on the testing mechanism 2.

[0023] The testing mechanism 2 includes a high support platform 21 installed on the rear side of the top of the workbench 1, a low support platform 22 installed on the front side of the top of the workbench 1, and side support platforms 23 installed on both sides of the workbench 1. The top of the high support platform 21, the low support platform 22, and the side support platform 23 are respectively provided with some components of the contour block 24.

[0024] It should be noted that the workbench 1 serves as the installation base for the entire device and is made of high-strength aluminum alloy to ensure stability during the testing process; the testing mechanism 2 is fixedly installed on the workbench 1 and is used to position and deform the product 3 to be tested; the product 3 to be tested is placed on the contour block 24 of the testing mechanism 2, and rapid positioning is achieved through the contour block 24.

[0025] In addition, the contour block 24 is divided into multiple sections, which can be detachably installed on the top of the high support platform 21, the low support platform 22 and the side support platform 23 respectively. Its shape is adapted to the inner or outer surface of the product 3 to be tested. By replacing the contour block 24, it can be adapted to different models of front windshield trim panels.

[0026] Several sets of horizontal tilting mechanisms 25 are evenly arranged on the high support platform 21, and each set of horizontal tilting mechanisms 25 is equipped with a dial gauge 26 at its front end.

[0027] It should be noted that the height of the high support platform 21 is adapted to the height of the rear side of the product 3 to be tested; through the flipping horizontal flipping mechanism 25, the detection end of the dial gauge 26 can quickly contact the upper surface of the product 3 to be tested, so as to realize the upper surface type variable detection.

[0028] The low support platform 22 is provided with several sets of bases 27, and each set of bases 27 is provided with a detection shaft 28 that is adapted to it.

[0029] It should be noted that the height of the low support platform 22 is lower than that of the high support platform 21, and it is adapted to the front shape height of the product 3 to be tested; the top of the detection shaft 28 contacts the lower surface of the product 3 to be tested, which not only plays an auxiliary positioning role, but also helps to judge the deformation of the lower surface through the force feedback of the detection shaft 28.

[0030] A side dial gauge 29 is provided on the opposite side of each of the two sets of side support platforms 23.

[0031] It should be noted that the inner side of the side support platform 23 is matched with the side distance of the product 3 to be tested; the detection end of the side dial gauge 29 is horizontally pointed to the side of the product 3 to be tested, and is used to detect side-type variables.

[0032] The following points apply to product testing:

[0033] Upper surface deformation measurement: Multiple sets of horizontal flipping mechanisms 25 are installed on the high support platform 21; each mechanism can be flipped down independently like a "door"; when it is flipped down, the probe of the dial indicator 26 fixed at its front end will press against the upper surface of the product 3; by comparing the dial indicator reading with the standard value, the deformation at that point can be obtained; multi-point measurement can comprehensively reflect the flatness of the upper surface of the product;

[0034] Mounting hole position measurement: Multiple sets of bases 27 are set on the low support platform 22, and a detection shaft 28 of a specific diameter is inserted into each base 27; the operator tries to insert the detection shaft 28 into the corresponding mounting hole of the product 3. If it can be inserted smoothly without obvious shaking, it means that the position of the hole is qualified; otherwise, it is unqualified.

[0035] Side deformation measurement: Side dial gauges 29 are installed on the outside of the two side support platforms 23 respectively; when the product 3 is placed, the probe of the side dial gauge 29 will automatically press against the side edge of the product 3 and directly read the lateral deformation.

[0036] The specific working method is described below using specific embodiments:

[0037] Example:

[0038] First, gently place the product 3 to be tested onto the contour block 24 of the testing mechanism 2, allowing it to fit naturally. Then, sequentially flip all the horizontal flipping mechanisms 25 on the high support platform 21, observing and recording the readings of each upper dial gauge 26. Simultaneously, observe the readings of the side dial gauges 29 on both sides. Next, attempt to insert all the testing shafts 28 on the low support platform 22 into the corresponding mounting holes of the product 3. Finally, by combining the readings of all dial gauges and the pass / fail status of the testing shafts, quickly determine whether the product 3 is qualified, and accurately determine the location and size of its deformation, providing a direct basis for subsequent repair or process improvement.

[0039] Example:

[0040] When testing the lower windshield trim panel of another model, the original profile block 24 needs to be removed: unscrew the positioning pins and bolts, and remove the profile block that is compatible with the original product; then install the new profile block: select the profile block that is compatible with the new product, position it with the positioning pins, and fix it with bolts; then adjust the position of the testing element: according to the outer dimensions of the new product, fine-tune the installation position of the horizontal flipping mechanism 25, the height of the side dial indicator 29, and the specifications of the testing shaft 28, and the testing can begin. The entire adaptation process only takes 10-15 minutes.

[0041] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
