Embodiment 1

[0029] As shown in the figure, the patent’s tooling for JW4G frame fast assembly is characterized by: including the main platform, four-corner height platform, middle height platform, adjustment and compression device 1, adjustment and compression device 2, End beam positioning stops and pins.

[0030] Two sets of four-corner height platforms are set opposite to each other at the four corners of the main platform, which are used to position and carry the two side beams in the JW4G frame.

[0031] The four-corner height platform includes the first platform, the side beam positioning block, the side beam front and rear adjustment device and the end beam positioning plate; the first platform is used to connect the main platform and support the side beam; the side beam positioning block is arranged on the first platform for Limit the side beams so that the two side beams are parallel to each other and the distance matches the length of the beam; the front and rear adjustment devices...

Abstract

The invention discloses a tool used for rapid assembly of a JW4G frame. The tool comprises a main platform, two groups of four-corner height platforms, two middle height platforms, adjusting and pressing devices, four end beam positioning backstops and pin shafts, wherein the four-corner height platforms are arranged at the four corners of the main platform in a pairwise opposite manner; the adjusting and pressing devices comprise portal frames, connecting plates, nuts, vertical screw rods, transverse screw rods and moment arm rods; the two middle height platforms are arranged on the main platform; and the four end beam positioning backstops are respectively arranged on the outer sides of the main platform below the four four-corner height platforms, and are pairwise matched to be used for bearing and positioning two end beams to allow the two end beams to have the verticality. By employing the tool, the positioning of side beams, cross beams and the end beams during the assembly is realized; frame deformation in an assembly welding process is avoided; the effects of the rapid and efficient assembly and time saving are achieved; and the assembly quality is ensured.

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 ...
