Description
Technical Field
The utility model relates to a car side wall welding pre-assembly technology, in particular to an automatic pre-assembly device for car side wall welding.
Background
The welding of the side walls of the car is to weld the left and right side walls of the car body on the bottom plate, wherein the side walls refer to the door frames on the left and right sides of the car and the supporting parts of the fender and the trunk, and are main components of the car body (see figure 1, A is the side wall of the car and B is a conveying frame). Generally, the car side wall and the car bottom plate are fixedly connected together in an automatic welding mode, namely, the car side wall and the car bottom plate are welded together on an assembly line by an automatic welding machine (namely a manipulator). In order to ensure the accuracy of the welding line, the car side wall and the car bottom plate are pre-fixed by the hasps, so that the car side wall is welded at the set position of the car bottom plate. The hasp is a structure which enables two metal pieces to be connected together through metal deformation and comprises an L-shaped folded edge and a corresponding edge; the L-shaped folded edge is usually arranged on one metal piece to be connected (such as a car floor), and a corresponding edge is arranged at a position corresponding to the other metal piece to be connected (such as the bottom of a side wall of a car). When the two are required to be connected together, the corresponding edges are overlapped and placed on the inner side of the L-shaped folded edge, the protruding part of the L-shaped folded edge is folded by adopting manual hammer knocking or a special folding tool, and the corresponding edges are firmly wrapped, so that the fixed connection between the two is realized (see the attached drawing 2, in the drawing, a is the L-shaped folded edge, and b is the corresponding edge). In addition, the process of pre-fixing the car side wall on the car bottom plate through the hasp is called pre-assembly. Usually, a plurality of L-shaped folded edges and corresponding edges (i.e. buckles) corresponding to each other are arranged at the combination part of the car floor and the car side wall. Taking a certain type of car as an example, a transverse forward hasp I is arranged at the joint of a car side wall trunk support and a car bottom plate, a vertical upward hasp II and a vertical upward hasp III are respectively arranged at the joints of the bottoms of a front door frame and a rear door frame of the car side wall and the car bottom plate, and a vertical downward hasp IV is arranged at the joint of a car side wall fender support and the car bottom plate, so that four hasps are totally arranged. The snap fasteners IV which are vertically downward at the joint part of the fender support and the base plate are of a double-snap-fastener structure (namely, a structure formed by two snap fasteners which are arranged side by side), and the rest are of a single-snap-fastener structure (see figure 1).
In the prior art, the car side wall welding and pre-splicing method adopts a conveying frame to lift and convey the car side wall to the side surface of a car floor (see figure 1, in the figure, A is the car side wall and B is the conveying frame), and because the conveying frame is not provided with a positioning mechanism, the car side wall can only be positioned near a set position of car side wall welding (at this time, the corresponding side and the L-shaped folded edge are not overlapped together) after being conveyed to the side surface of the car floor, and the car side wall also needs to be manually placed to the set position (at this time, the corresponding side and the L-shaped folded edge are overlapped together). Then, the L-shaped folding edges are folded one by adopting a hammer or a special folding tool, so that the process of pre-assembling the side wall and the bottom plate of the car is completed.
Obviously, the welding and pre-splicing method for the side wall of the car in the prior art has the problems of high labor intensity, poor working environment, low efficiency and the like.
