A flexible robot welding tool for the chassis frame of a corn harvester

Abstract

The invention relates to a welding tool for a chassis frame of a maize harvesting machine, in particular to a flexible robot welding tool for the chassis frame of the maize harvesting machine. The flexible robot welding tool for the chassis frame of the maize harvesting machine is low in machining and manufacturing cost and convenient to clamp, labor intensity of workers is low, the locating precision of transverse beams and longitudinal beams of the frame can be guaranteed, welding deformation can be reduced, flexibility is good, interference cannot be generated during welding after overturn, and a front face and a back face can be welded on one tool through one-time locating. The flexible robot welding tool for the chassis frame of the maize harvesting machine has the advantages that the workers can load and unload workpieces conveniently, and labor intensity is low; the position of a frame transverse beam locating mechanism and the position of a frame longitudinal beam locating mechanism on a bearing frame can be adjusted continuously, welding of frames of different series and different types can be achieved, and flexibility is good; overturn of the tool can be achieved through a welding positioner, and robot welding is achieved; the machining and manufacturing cost is low, operation is convenient, working efficiency is improved, and needs of enterprises are met.

Description

technical field [0001] The invention relates to a welding tool for a chassis frame of a corn harvester, in particular to a flexible robot welding tool for a chassis frame of a corn harvester. Background technique [0002] At present, most of the welding tools for the chassis frame of the corn harvester 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’s transverse 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 corn harvester chassis frame welding tooling can be used for robot welding, but it is only for a single product, with poor flexibility, and cannot be used for welding different series and types of frames. The rare corn harvester chassis frame welding tooling ...
