Description

Technical Field

[0001] This utility model belongs to the field of shaping tooling technology, and more specifically, it relates to a fiberglass shaping tooling. Background Technology

[0002] After fiberglass products (such as car fronts) are installed on the bracket, they sag due to their own weight, resin shrinkage, and residual stress, resulting in plastic deformation that affects the product's precision and appearance. At this time, shaping fixtures are needed to assist in the process.

[0003] Based on existing technologies, it has been found that traditional jacking fixtures cannot adapt to the curved angle of the product surface, which can easily cause surface scratches. During the tightening process, the rotational friction of the threads can easily damage the surface coating of the product. The angle of the shaping mechanism is fixed, making it difficult to adapt to products with different curvatures. Hydraulic jacks are bulky and inflexible in operation, while ordinary screw fixtures have large rotational friction during tightening and the angle is not adjustable. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a fiberglass shaping fixture to solve the issues of traditional push-pull fixtures being unable to adapt to the curved angle of the product surface, easily causing surface scratches, the thread rotation friction during the tightening process easily damaging the product surface coating, and the fixed angle of the shaping mechanism making it difficult to adapt to products with different curvatures.

The stroke of the screw 3 here is set to 200mm. The connector 5 here is used to be installed inside the threaded hole on the screw 3 through the external thread. It can be easily replaced separately after damage, reducing maintenance costs. The modular design makes the replacement cost less than 10% of the overall tooling. The universal ball joint 6 is set to adapt to ±15° tilt angle. The universal joint 6 is set inside the universal joint 7. After contacting the product, it automatically locks the rotation and only transmits axial thrust to eliminate friction damage. The angle adaptation range of the universal joint 7 is ±20°.

[0026] Among them, such as Figure 3 As shown, the mounting base 1 is provided with mounting grooves 101; there are four sets of mounting grooves 101; the upper and lower mounting grooves 101 are arranged correspondingly to each other; the threaded holes on the side plate 102 correspond to the threaded holes on the fixing nut A2; the fixing nut A2 is set as an M18 hexagonal nut; the fixing nut A2 here provides a high load-bearing threaded interface, which enhances the torsional strength, and the force is sufficient to complete the shaping of the fiberglass product without damaging the threads.
