Embodiment Construction

[0035] Such as Figure 1a with Figure 1b As shown, the trunk lid in the present embodiment is formed by the upper cover plate 8 and the side cover plate 7, the upper cover plate 8 is a horizontal plate, the side cover plate 7 is a vertical plate, and the top edge of the side cover plate 7 The bends are horizontally lapped and lapped on the edge of the upper cover plate 8 to form a lapped welding zone.

[0036] Such as figure 2 shown and image 3 As shown, the structural form of the laser lap welding fixture of the body-in-white trunk lid robot on the welding position P in this embodiment is:

[0037] The top member 15a in the lower support 15 is supported on the bottom of the upper cover 8, and the side members 15b in the lower support 15 are supported on the inner side of the side cover 7; the first upper pressing head 16 is pressed against the upper cover 8 On the top, it forms a clamping for the upper cover plate 8 in the form of opening and closing relative to the top...

Abstract

The invention discloses a robot laser overlapping weld clamp for a white car body trunk lid. The top edge of a side cover plate is bent to form a horizontal overlapping edge to be in overlap joint with the edge of an upper cover plate to form an overlapping weld area. The robot laser overlapping weld clamp is characterized in that according to the structural form of the welding position of the robot laser overlapping weld clamp, a first upper press head abuts against the upper cover plate, and the upper cover plate is clamped by the first upper press head and a top component in an opposite opening form; and a second upper press head abuts against the horizontal overlapping edge of the side cover plate, and the overlap joint area is clamped by the second upper press head and the top component. The structural form of the welding position of the robot laser overlapping weld clamp is firm and stable, the flatness and connecting strength of a weld line can be guaranteed, and the laser overlapping weld quality of the trunk lid is improved.

Description

technical field [0001] The invention relates to a laser lap welding jig, which belongs to the technical field of mechanical fixtures, and more specifically relates to a laser lap welding jig for a robot-in-white trunk lid. Background technique [0002] Body laser welding is mainly used for the welding of automobile body frame structures, such as the welding of trunk lids. Traditional resistance spot welding has been gradually replaced by laser welding. The use of laser welding technology can improve the flexibility of product design, reduce manufacturing costs, and reduce the overlapping surface between plates, which not only reduces the amount of plates used, but also improves the connection strength of the body. When laser welding the trunk lid of a car, different fixture positioning and clamping methods have a great influence on the laser lap welding quality of the trunk lid of the body-in-white. In order to ensure the flatness and connection strength of the weld, it is n...
