Detailed Implementation

[0013] The following is combined with Figures 1 to 9 The bonding tooling for the intercity vehicle fiberglass box cover described in this utility model is described in detail.

[0014] The intercity vehicle fiberglass box cover bonding fixture of this utility model includes: a main body 1, a positioning boss 6, a positioning groove 5, a positioning clamp 3, and several workpiece positioning plates of different models.

[0015] like Figure 1 As shown, the main body 1 is an HPL board, which has a long lifespan and good molding effect. Multiple positioning bosses 6 are spaced along the length of the upper surface of both sides of the main body 1. Each positioning boss 6 has an inwardly opening positioning groove 5. Various types of workpiece positioning plates are placed in the positioning grooves 5 and positioned by two adjacent surfaces of the positioning grooves 5. Positioning clamps 3 are provided beside the positioning grooves 5 to clamp and fix the positioned workpiece positioning plates. The various types of workpiece positioning plates include stud workpiece positioning plates 2, L-shaped workpiece positioning plates 4, Z-shaped workpiece positioning plates 7, and U-shaped workpiece positioning plates 8.

[0016] The upper surface of one side of the main body 1 has four positioning bosses 6 of equal height. Three stud workpiece positioning plates 2 and one L-shaped workpiece positioning plate 4 are sequentially arranged in the positioning groove 5. The first stud positioning plate is shared for processing different products. Figure 2 As shown in Figure 4, the stud workpiece positioning plate 2 is L-shaped, with its vertical surface facing downwards. A round hole and an oblong hole for adjusting errors are arranged side-by-side on the vertical surface. This oblong hole ensures that the stud workpiece 9 can be assembled onto the stud workpiece positioning plate 2 within the required tolerance range, thus preventing the stud workpiece 9 from mismatching with the stud workpiece positioning plate 2 due to machining errors during processing. Figures 5 to 6 As shown, the L-shaped workpiece positioning plate 4 is a flat plate with grooves on its inner surface for positioning the three end faces of the horizontal plane of the L-shaped workpiece 10.

[0017] On the other side of the upper surface of the main body 1, four positioning bosses 6 of different heights are provided. The height of the third positioning boss 6 is similar to that of the positioning boss 6 on the opposite side, but higher than the first, second, and fourth positioning bosses on this side. Two U-shaped workpiece positioning plates 7, one U-shaped workpiece positioning plate 8, and one U-shaped workpiece positioning plate 7 are sequentially arranged in the positioning groove 5. The first and second U-shaped workpiece positioning plates 7 are shared for processing different products. For example... Figures 7 to 8 As shown, the main plane of the U-shaped workpiece positioning plate 7 has downward-curved edges on both sides and the front end for positioning the three sides of the U-shaped workpiece 11; as Figure 9 As shown, the U-shaped workpiece positioning plate 8 is provided with an L-shaped groove with openings in two directions, and the U-shaped workpiece 12 is positioned on three sides by the two vertical surfaces and the bottom surface of the L-shaped groove.

[0018] After the positioning plates of various models are used to position the workpieces of different products, the positioning clamps 3 are used to clamp and fix the positioned workpiece positioning plates and the workpieces below them, so as to realize the positioning and bonding of different metal workpieces on the back of the fiberglass box cover.

[0019] The intercity vehicle fiberglass box cover bonding fixture described in this utility model can process multiple products on a single set of fixtures, which greatly saves the cost of bonding fixtures, saves workshop space, makes the workshop layout more reasonable, and improves processing efficiency. In addition, it also has the advantages of long service life and good molding effect.

[0020] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
