The workpiece positioning plate is placed in the positioning groove and positioned by the two adjacent surfaces of the positioning groove; positioning clamps are provided next to the positioning grooves to clamp and fix the positioned workpiece positioning plate; two positioning recesses for placing positioning posts are also provided on the upper surface of the main body inside the positioning bosses.

[0005] Furthermore, the workpiece positioning plate includes a slotted positioning plate, a positioning hole positioning plate, a limiting hole positioning plate, and an end face positioning plate.

[0006] Furthermore, the lower surface of the slotted positioning plate is provided with grooves for positioning the three sides of the workpiece; the positioning hole positioning plate is provided with round holes for positioning the stud workpiece; the limiting hole positioning plate is provided with elongated holes for positioning the stud workpiece within tolerance range; and the end face of one end of the end face positioning plate is adapted to the end face of the workpiece.

[0007] Furthermore, two sets of positioning bosses of equal height are provided on the upper surfaces of both sides of the main body. These two sets of positioning bosses are higher than other positioning bosses. Positioning grooves are symmetrically arranged on the opposing positioning bosses, and a double-pinch buckle-groove positioning plate is placed together in the symmetrical positioning grooves.

[0008] Furthermore, the positioning recesses on the upper surface of the main body and the positioning columns therein are both circular in cross-section.

[0009] Furthermore, the main body is made of HPL board material. It is sturdy, durable, does not deform, has a long lifespan, and provides good molding results.

[0010] The fiberglass flat cover bonding fixture for intercity vehicles described in this utility model has a simple and precise positioning method, which greatly improves the operating efficiency and the accuracy of the bonding installation, and reduces the processing defect rate and production cost. In addition, it is sturdy, durable and does not absorb moisture, which greatly reduces the risk of deformation of the bonded fiberglass products, and has a long service life and good molding effect.

Detailed Implementation

[0013] The following is combined Figures 1 to 10 The present invention provides a detailed description of the bonding fixture for the fiberglass flat cover plate of the intercity vehicle.

[0014] The intercity vehicle fiberglass flat cover plate assembly tooling of this utility model includes: a main body 1, a positioning boss 8, a positioning groove 9, a single clamping point grooved positioning plate 2, an oblong hole positioning plate 3, a round hole positioning plate 4, an end face positioning plate 5, a positioning post 6, a double clamping point grooved positioning plate 7, and a quick clamp 11.

[0015] like Figure 1 As shown, the main body 1 is an HPL board, which is sturdy, durable and non-hygroscopic, greatly reducing the risk of deformation of the bonded fiberglass products, resulting in good molding effect and long service life.

[0016] The upper surfaces of both sides of the main body 1 are provided with positioning bosses 8 of varying heights at intervals along the length direction. Each positioning boss 8 has an inwardly opening positioning groove 9. Different types of workpiece positioning plates are placed within the positioning grooves 9 and positioned by two adjacent surfaces of the grooves 9. Positioning clamps 11 are located beside the positioning grooves 9 to clamp and fix the different positioning plates of the positioned workpieces. Positioning pins 6 are also placed inside the positioning bosses 8 of the main body 1.

[0017] The different styles of workpiece positioning plates include a single-grip slotted positioning plate 2, a positioning positioning plate 3, a limiting hole positioning plate 4, an end-face positioning plate 5, and a double-grip slotted positioning plate 7. The upper surfaces of both sides of the main body 1 are provided with two sets of positioning bosses 8 of equal height. These two sets of positioning bosses are higher than other positioning bosses, and the double-grip slotted positioning plate 7 is positioned on these two sets of positioning bosses.

[0018] like Figure 2 and Figure 3 As shown, the lower surface of the single-pinch groove positioning plate 2 is provided with grooves for positioning the three sides of the workpiece 10.
