Description

Technical Field

[0001] This utility model relates to the field of tooling, specifically a tooling for assembly support and rapid detection of part length. Background Technology

[0002] During vehicle assembly, the ventilation cover undergoes rapid inspection along its Z-axis mounting surface to match the gaps and surface differences of the hood. However, production cycles are tight, and the parts are irregularly shaped, making it impossible for employees to inspect 100% of the parts using the appropriate fixtures. This compromises the prevention of deformation and leads to defects. Furthermore, employee assembly is inconvenient and cannot guarantee that the assembly process won't cause deformation. Therefore, a tooling system for assembly support and rapid part length inspection was developed to address these issues. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a tooling for assembling support and quickly detecting the length of parts, including a base plate. The top of the base plate has corner support columns at both ends for supporting the four corners of a ventilation cover. The top of the base plate is fixed with a first front support column, a second front support column, and a third front support column for supporting the front side of the ventilation cover. The top of the base plate is also fixed with a first rear support column, a second rear support column, and a third rear support column for supporting the rear side of the ventilation cover. The top of each corner support column, first front support column, second front support column, third front support column, first rear support column, second rear support column, and third rear support column has a contoured surface that contacts and engages with the ventilation cover. The top of the base plate is also equipped with a positioning and detection device for limiting the ventilation cover.

[0004] Preferably, the tops of the first and third front support columns are positioned directly opposite the top edge of the ventilation cover.

[0005] Preferably, the top of the corner support column is positioned directly opposite the reinforcing rib of the ventilation cover, the top of the first rear support column is positioned directly opposite the bend of the ventilation cover, and the tops of the second and third rear support columns are positioned directly opposite the clamping plate of the ventilation cover.

[0006] Preferably, the top of the second front support column is provided with a limiting groove that mates with the ear plate of the ventilation cover, and a positioning column that mates with the mounting hole on the ear plate is fixed in the limiting groove.

[0007] Preferably, a limiting post is fixed to the top of the base plate, and the inner side of the limiting post is provided with an arc-shaped groove that cooperates with the ear plate of the ventilation cover.

[0008] Preferably, the positioning detection device includes a column fixed to the top of the base plate, a limiting plate is hinged to one side of the column via a pivot, a blocking block for blocking the limiting plate is provided on the side of the column, and the limiting plate is provided with a groove for limiting the edge of the ventilation cover and an L-shaped groove for limiting the bending of the ventilation cover.

[0009] Beneficial effects:

[0010] Improved inspection efficiency: By designing a special contoured surface and positioning device, the ventilation cover can be quickly and accurately positioned on the tooling, reducing the time required for traditional manual inspection and greatly improving production efficiency.

[0011] Enhanced testing accuracy: By utilizing the positioning pins in the limiting groove to match the mounting holes on the ear plate, and the precise matching of the L-shaped groove to the bends, it is ensured that every tested ventilation cover meets high quality standards, effectively reducing the defect rate.

[0012] To prevent deformation: The fixture provides comprehensive support for the ventilation cover plate through end corner support columns, first front support columns, second front support columns, third front support columns, first rear support columns, second rear support columns, and third rear support columns. In particular, special treatment is carried out at high-strength locations such as reinforcing ribs and bends to ensure that the ventilation cover plate will not undergo any form of deformation during the inspection process.

[0013] Simplified operation process: The entire testing process is simple and intuitive. Employees only need to place the ventilation cover in the correct position and fix it with the limiting plate to complete the test. This greatly simplifies the operation steps, lowers the technical threshold, and reduces training costs.

[0014] Improving product quality: The above design not only ensures that each ventilation cover is qualified before assembly, but also avoids secondary damage or deformation caused by improper assembly due to its stable support structure, thereby improving the overall quality of the final product.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figures 1 to 6 A tooling for assembling support and quickly detecting the length of parts includes a base plate 1, with corner support columns 3 at both ends of the top of the base plate 1 for supporting the four corners of a ventilation cover 2. In addition, a first front support column 4, a second front support column 5, and a third front support column 6 are fixed to the top of the base plate 1 to support the front side of the ventilation cover 2; and a first rear support column 7, a second rear support column 8, and a third rear support column 9 are fixed to support the rear side of the ventilation cover 2. The tops of these support columns are all provided with contoured surfaces that fit tightly in contact with the ventilation cover 2, ensuring stable support while facilitating initial positioning of the ventilation cover 2. To further limit the position of the ventilation cover 2, a positioning detection device 15 is also installed on the top of the base plate 1.

[0024] Specifically, the tops of the first front support column 4 and the third front support column 6 are positioned directly opposite the flange of the ventilation cover 2, ensuring the stability and strength of this part of the structure. The corner support column 3 is positioned directly opposite the reinforcing rib of the ventilation cover 2, utilizing its high strength characteristics to bear greater forces without deformation. Similarly, the first rear support column 7 is located at the bend of the ventilation cover 2, while the second rear support column 8 and the third rear support column 9 are positioned directly opposite the retaining plate, also providing stable support based on the high rigidity of these locations.

[0025] The top of the second front support column 5 is provided with a limiting groove 16, in which a positioning column 10 is installed to cooperate with the mounting holes on the ear plate of the ventilation cover 2, thereby achieving a precise positioning function. The top of the base plate 1 is also fixed with a limiting column 11, which has an arc-shaped groove 17 designed on its inner side to cooperate with the other ear plate of the ventilation cover 2, thereby enhancing the overall stability.

[0026] The positioning and testing device 15 consists of a column 12, a limiting plate 13 hinged to one side of the column, and a blocking block 14. The limiting plate 13 is provided with a groove 18 and an L-shaped groove 19, which are used to limit the edge and bend of the ventilation cover 2, respectively. When the ventilation cover 2 is placed on the fixture and tested using this device, if the L-shaped groove 19 cannot completely fit with the bend of the ventilation cover 2 or the groove 18 cannot hold the edge of the ventilation cover 2, it indicates that there is a quality problem with the ventilation cover 2.

[0027] This tooling not only improves inspection efficiency and reduces the defect rate caused by inaccurate manual inspection, but also effectively avoids deformation problems that may occur during assembly through precise positioning and support mechanisms, significantly improving assembly quality and work efficiency.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
