[0002] See attached Figure 1 The figure shows a curved door panel used in rail transit vehicles. The shape of the curved door panel needs to match the front curve of the vehicle. The curved door panel includes a door frame and a glass and fiberglass cover plate bonded to the door frame. When the curved door panel is bonded and assembled, the door frame is supported on a specific tooling, and then the glass and the cover plate are bonded by applying glue to the door frame.

[0003] At present, in order to achieve the precise positioning of the various components of the curved door panels and facilitate the subsequent installation of parts, the tooling used for bonding this type of curved door panels is manufactured using a multi-axis machining center. However, the types of curved door panels and the curved surfaces of each curved door panel are different. Therefore, when using a multi-axis machining center to manufacture the tooling, on the one hand, the processing material volume is large and the tooling is bulky; on the other hand, the production cost is high, and it cannot adapt to the bonding and positioning of curved door panels.

[0004] Therefore, there is an urgent need for a curved door panel bonding tool to reduce the cost of tooling production and adapt to small-batch curved door panel production. Utility Model Content

[0005] In view of the above technical problems, the utility model provides a curved door panel bonding tool, which is used to solve the problem that the existing curved door panel bonding tool is high in cost when produced using a multi-axis machining center and cannot adapt to the bonding and positioning of curved door panels.
