Problems solved by technology

In the past, the flipping bracket of the welding fixture was bulky and heavy, and at least two or more people were required to operate it together. The operation was complicated and inefficient, and the welding quality could not be guaranteed.
At the same time, during the body manufacturing process, large outer panel covering parts such as the top cover and side wall are easily deformed, and it is not easy to transport them over a long distance in the air with a spreader

Abstract

The invention discloses an overturning fixture, a conveying line and a use method of the conveying line, and belongs to the technical field of automobile production. The overturning fixture comprisesa fixture base, lifting cylinders are fixedly installed at both ends of the fixture base, piston rods of the two groups of lifting cylinders are fixedly connected with lifting frames, overturning bearings are fixedly installed on the two groups of lifting frames, a same welding fixture is fixedly connected with inner rings of the two groups of overturning bearings, an overturning motor is fixedlyinstalled on one of the lifting frames, and an output shaft of the overturning motor is fixedly connected with the welding fixture. The conveying line further comprises a conveying base, the conveyingbase is fixedly arranged on the middle part of the fixture base and the two are arranged vertically, a guide rail II, a rodless cylinder and a locking assembly are arranged on the conveying base, a movable conveying trolley is arranged on the guide rail II, a limit block II is fixedly arranged at the bottom of the conveying trolley, the rodless cylinder is used to push the conveying trolley to move back and forth, and the locking assembly is used to limit the position of the limit block II, so that installation space is saved, the degree of automation is high, and welding quality is high.

Description

technical field [0001] The invention relates to the technical field of automobile production and manufacturing, in particular to a welding jig that can be turned over, a conveying line and a method for using the conveying line. Background technique [0002] With the continuous improvement of the automation level of the automobile welding production line, the method of loading parts by robot grippers has become more and more widely used. Usually, after the welded workpiece is placed on the loading table, the robot gripper is lifted from above the workpiece. Grab the workpiece directly. But sometimes, according to the structure of the workpiece and the needs of the enclosing manufacturing of the body, the robot gripper needs to grab the workpiece from the reverse side of the workpiece to facilitate the on-line needs of the workpiece, so that the workpiece needs to be turned over after welding. In the past, the flipping bracket of the welding fixture was bulky and heavy, requi...
