Description

Technical Field

[0001] The utility model relates to the technical field of turnover tooling, in particular to a turnover device for welding the inner seam of a main beam. Background Art

[0002] The welding of the inner seam of the main beam is done by turning the workpiece to the flat welding position with a turning tool. The workers lie in the beam box to weld the inner seam. The labor intensity is high. After welding one side, the main beam is turned to the other side and the inner seam of the other side is welded in the flat welding position. Manual welding is labor-intensive and labor-intensive, and the working environment is harsh. At present, the main beam is mainly turned by a pair of double L-shaped turning tools, that is, 4 sets of L-shaped tools are used in combination. When the tool turns the main beam, the main beam is placed on the L-shaped tool. When turning the main beam to one side, a pair of L-shaped tools turns to one side. When turning the main beam to the other side, another pair of L-shaped tools turns to the other side. Two pairs of L-shaped tools realize the turning of the main beam to both sides. The L-shaped turning tool requires digging the foundation and occupies a large space. When used in conjunction with a welding robot, the L-shaped turning tool appears bulky and the equipment is backward. Utility Model Content

The support arms rotate around the support axis 2.8 to realize the flipping of the main beam. After the flipping is completed, the main beam is placed flat on the matching support platform 1, and the support seat 2.3 can run along the linear slide rail. The two support arms are at a 45° angle to the horizontal plane (that is, the two support arms are at 90°) to drag the main beam along the linear slide rail 2.1. When the main beam is dragged to the corresponding position, the two support arms are slowly flattened, and the main beam is placed on the matching support platform 1;

[0017] It should be noted that the support arm 2.5 is connected to the support arm 1 2.6 via the rotating shaft 2.9, the cylinder 2.4 is hinged to the support arm 1 2.6 via the supporting shaft 2.8, and the support arm 1 2.6 is hinged to the supporting seat 2.3 via the supporting shaft 2.8, that is, the cylinder end of the cylinder 2.4 is located in the opposite extension direction of the support arm 1 2.6, so that the two cylinders can leverage each other;
