Problems solved by technology

[0004] At present, most agricultural machinery chassis frame welding jigs can only be used for manual welding, and there are generally insufficient or over-constraints. When the constraints are insufficient, the clamping and positioning of the frame beams and longitudinal beams are not accurate, resulting in inconsistent weld gaps and large welding deformation. ; When over-constrained, it is difficult to clamp the frame beams and longitudinal beams, and the labor intensity of workers is high
The rare agricultural machinery chassis frame welding jig can be used for welding, but only for a single product, with poor flexibility, and cannot be used for welding different series and various types of frames

Embodiment Construction

[0018] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0019] Such as figure 2 As shown, a flexible welding jig for an agricultural machinery chassis frame includes a frame beam positioning mechanism, a frame longitudinal beam positioning mechanism, a bearing mechanism, and a limit mechanism.

[0020] The load turning mechanism includes a transverse load frame 12 , a vertical load frame 2 , a cylindrical boss 4 , and a connector 1 . Wherein, the longitudinal bearing frame 2 is bolted to the transverse bearing frame 12 through the connector 1 , and the cylindrical boss 4 is bolted to the longitudinal bearing frame 2 . The connection of this part constitutes the load-bearing mechanism of the flexible welding jig of the agricultural machinery chassis frame, which is used for load bearing. Moreover, the chuck of the positioner clamps the cylindrical boss 4 to realize the flipp...

Abstract

The invention relates to a flexible welding jig for a vehicle frame, in particular to a flexible welding jig for an agricultural machinery chassis frame. The whole equipment is divided into four parts: the bearing turning mechanism, the frame beam positioning mechanism, the frame longitudinal beam positioning mechanism, and the limit mechanism. When the present invention works, the positions of the frame beam positioning mechanism and the frame longitudinal beam positioning mechanism on the load-bearing frame can be continuously adjusted, which can realize the welding of different series and various types of frames, and has good flexibility; The flipping of the jig realizes welding; the invention has the advantages of convenient loading and unloading of workpieces for workers, low labor intensity; low manufacturing cost, convenient operation, improved work efficiency, and meets the needs of vehicle manufacturing enterprises.
