Flexible welding fixture for vehicle frame

Abstract

The invention relates to a flexible welding fixture for a vehicle frame, in particular to a flexible welding fixture for the vehicle frame of an agricultural mechanical chassis. The whole equipment is divided into a loading turnover mechanism, a vehicle frame beam positioning mechanism, a vehicle frame stringer positioning mechanism and a limit mechanism. When the flexible welding fixture works, positions of the vehicle frame beam positioning mechanism and the vehicle frame stringer positioning mechanism on a loading frame can be adjusted constantly, welding of the vehicle frames in various series and types can be achieved, and the flexibility is good; turnover of the fixture can be achieved to complete welding through a positioner; the flexible welding fixture for the vehicle frame has the advantages of being convenient to load and unload workpieces manually, low in labor intensity, low in manufacturing cost, convenient to operate, and high in work efficiency and can meet needs of vehicle manufacture enterprises

Description

[0001] (1) Technical field [0002] 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. [0003] (2) Background 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, the clamping of the frame beams is difficult, and the labor intensity of the workers is high. The rare agricultural machinery chassis frame welding jig can be used for welding, but it is only for a single product, with poor flexibility, and cannot be used for welding different series and various types of frames.
