Abstract

This patent introduces a tooling for quick assembly of JW4G frames, including main platform, four-corner height platform, middle height platform, adjustment and pressing device, end beam positioning stopper and pin shaft; two sets of four-corner height platforms two by two Relatively set at the four corners of the main platform; the adjustment and pressing device includes a gantry frame, a connecting plate, a screw nut, a vertical screw, a horizontal screw and a lever; two middle height platforms are set on the main platform; four The end beam positioning stoppers are respectively arranged on the outside of the main platform under the four four-corner height platforms, and are used to carry the two end beams and locate the verticality of the two end beams. This patent uses tooling to realize the positioning of side beams, cross beams and end beams during assembly, and to prevent frame deformation during assembly and welding, so as to achieve fast and efficient assembly, save time and ensure the quality of assembly.

Description

technical field [0001] The invention relates to the technical field of manufacturing railway engineering vehicles, in particular to a tooling for fast assembly of JW4G frames. Background technique [0002] The JW4G frame is a supporting part of the railway engineering vehicle. It is currently the main product of the workshop. Its structure is composed of side beams, cross beams and end beams. The diagonal line is ±2mm, and the height difference of the four corners of the frame is ±2mm; when assembling, the side beams, beams and end beams need to be adjusted in place at the same time, often the size cannot be taken into account at the same time, and the deformation caused by stress shrinkage during welding will cause If the height difference in the width direction or the four corners of the frame exceeds the standard, it will bring difficulties to the work of the accessory assembly in the subsequent process or increase the workload of correction. This requires the design and ...
