[0034] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. The technical methods of the present invention will be further described, but the present invention is not limited to these embodiments.

[0035] like Figure 1-3As shown, this utility model provides a riveting fixture for the front and rear crossbeams of an automobile, comprising:

[0036] The base plate 100 is equipped with a front crossbeam positioning module 200 and a rear crossbeam positioning module 300.

[0037] The front crossbeam positioning module 200 is composed of a first front and rear positioning block 210, a first left and right positioning block 220 and a first bottom positioning block 230. The first front and rear positioning block 210, the first left and right positioning block 220 and the first bottom positioning block 230 together form a space for placing the front crossbeam product 400.

[0038] The rear crossbeam positioning module 300 is composed of a second front and rear positioning block 310, a second left and right positioning block 320 and a second bottom positioning block 330. The second front and rear positioning block 310, the second left and right positioning block 320 and the second bottom positioning block 330 together form a space for placing the rear crossbeam product 500.

[0039] In other words, the riveting fixture provided in this embodiment is specifically designed for riveting operations of aluminum automotive front and rear crossbeams. By setting up the front crossbeam positioning module 200 and the rear crossbeam positioning module 300, the various surfaces of the front crossbeam product 400 and the rear crossbeam product 500 can be positioned to ensure that the products will not be skewed or displaced during the riveting process, thereby avoiding scrapping of the products due to rivet tilting or insufficient perpendicularity during the riveting process.

[0040] It should also be noted that there is a distance between the front crossbeam positioning module 200 and the rear crossbeam positioning module 300, and there is a height difference between the first bottom positioning block 230 and the second bottom positioning block 330. Therefore, after the front crossbeam product 400 and the rear crossbeam product 500 are installed, there is a distance between the two products and a height difference between the two products, which facilitates simultaneous riveting of the front and sides of the products and improves work efficiency.

[0041] Preferably, the first front and rear positioning blocks 210 are provided in multiple parts, and each part abuts against the front and rear end faces of the front crossbeam product 400.

[0042] Specifically, when the number of the first front and rear positioning blocks 210 is set to an odd number, their positions against the front and rear ends of the front crossbeam product 400 are staggered.

[0043] When the number of the first front and rear positioning blocks 210 is set to an even number, their positions against the front and rear end faces of the front crossbeam product 400 are symmetrically distributed.

[0044] Whether the distribution is staggered or symmetrical, it can ensure that the front crossbeam product 400 remains in a fixed position and does not shift when the side is riveted, thereby ensuring the perpendicularity of the rivets and guaranteeing the quality of riveting.

[0045] Preferably, the first left and right positioning blocks 220 are provided in two pieces and respectively abut against the left and right end faces of the front crossbeam product 400 to ensure that the front crossbeam product 400 will not shift in the left and right directions.

[0046] Preferably, at least two first bottom positioning blocks 230 are provided and located on the same straight line. The top surface of the first bottom positioning block 230 has a positioning groove 231. The bottom of the front crossbeam product 400 is embedded in the positioning groove 231. The positioning groove 231 is adapted to the structural features of the front crossbeam product 400, further ensuring the stability and firmness of the front crossbeam product 400 after installation.

[0047] In summary, by setting the first front and rear positioning blocks 210, the first left and right positioning blocks 220 and the first bottom positioning block 230, the front crossbeam product 400 can be positioned and limited in all directions, thereby ensuring the stability of the product position during the riveting process and ensuring good riveting quality.

[0048] Preferably, multiple second front and rear positioning blocks 310 are provided, and they respectively abut against the front and rear end faces of the rear crossbeam product 500.

[0049] Similarly, when the number of the second front and rear positioning blocks 310 is set to an odd number, their positions against the front and rear end faces of the rear crossbeam product 500 are staggered.

[0050] When the number of the first front and rear positioning blocks 210 is set to an even number, their positions against the front and rear end faces of the rear crossbeam product 500 are symmetrically distributed.

[0051] The second front and rear positioning blocks 310 ensure that the rear crossbeam product 500 will not shift in the front and rear directions.

[0052] Preferably, the second left and right positioning blocks 320 are provided in two pieces and respectively abut against the left and right end faces of the rear crossbeam product 500 to ensure that the rear crossbeam product 500 will not shift in the left and right directions.

[0053] Preferably, at least two second bottom positioning blocks 330 are provided and located on the same straight line, and the rear crossbeam product 500 is placed horizontally on each of the second bottom positioning blocks 330.

[0054] Similarly, by setting the second front and rear positioning blocks 310, the second left and right positioning blocks 320 and the second bottom positioning blocks 330, the rear crossbeam product 500 can be positioned and limited in all directions, thereby ensuring the stability of the product position during the riveting process and ensuring good riveting quality.

[0055] It is also worth mentioning that the first front and rear positioning blocks 210, the first left and right positioning blocks 220, the second front and rear positioning blocks 310, and the second left and right positioning blocks 320 are all provided with adjustment grooves 240. Fasteners pass through the adjustment grooves 240 and are connected to the base plate 100. Each positioning block can move along the direction of its respective adjustment groove 240.

[0056] In other words, after each positioning block is installed on the base plate 100, its position is not fixed, but can be moved along the direction of the adjustment groove 240, thereby meeting the riveting requirements of front crossbeam product 400 and rear crossbeam product 500 of different sizes, and improving the versatility and adaptability of the tooling.

[0057] To further improve the versatility and adaptability of the tooling, the base plate 100 can also be provided with adjustment slots 110 at the locations of each positioning block. The adjustment slots 110 are perpendicular to the adjustment slots 240 of each positioning block. By moving the fasteners within the adjustment slots 110, the position of the positioning block can be adjusted. For example, when the adjustment slot 240 of a positioning block is set vertically on the base plate 100, the adjustment slots 110 at its bottom are set horizontally. Thus, the position of the positioning block can be adjusted vertically and horizontally. This design allows the tooling to be adjusted within a wider range to adapt to products of different specifications.

[0058] In addition, handles 120 are provided at each corner of the base plate 100 to facilitate the handling of tools by operators.
