Embodiment 1

[0030] As shown in the figure, a tooling for rapid assembly and welding of frame side beams in this patent includes a main frame 2, a positioning baffle 4, a first pressing device 6, a second pressing device 3 and a pin shaft 5 .

[0031] The upper part of the main frame 2 is a plane, and the middle part of the plane is provided with a concave part matching with the lower protrusion of the side beam 1; the concave part is used for positioning and carrying the side beam 1.

[0032] The upper part of the positioning baffle 4 is provided with a first connecting hole 8, and the side is provided with a rib 9; the width of the rib 9 is equal to the horizontal distance from the outer side of the vertical plate of the side beam 1 to the outer edge of the upper cover.

[0033] The first pressing device 6 includes a frame body 12, a vertical lead screw 11 and a horizontal lead screw 13; the frame body 12 is a bent rod-shaped member, and the bent rod-shaped member includes a horizontal p...

Embodiment 2

[0041] When using the tooling for fast assembly and welding of frame side beams as described in Embodiment 1 to carry out side beam 1 pairing operation, the first step is the vertical plate and partition of the prefabricated side beam, that is, the vertical plate and The partition points are fixed as a whole; the second step is to assemble and weld the lower cover plate of the side beam, the vertical plate and the partition plate, specifically, first place the lower cover plate in the depression of the main frame 2, and make the lower The left side of the plate fits the rib 9 of the positioning baffle plate 4, and then the prefabricated vertical plate and partition plate are placed on the lower cover plate, and the horizontal lead screw 2 of the second pressing device 3 at the two ends of the main frame 2 is adjusted. 14. Make the vertical plate coincide with the center of the lower cover plate; then connect each first pressing device 6 with the corresponding positioning baffle...

Abstract

The invention discloses a quick assembling and welding fixture used for side beams of an engineering car framework. The quick assembling and welding fixture comprises a main frame, positioning baffles, first compression devices, second compression devices and hinge pins. The fixture is used for solving the problems that welding deformation is caused and the size is difficult to control during assembly and welding of the side beams; by structural study and analysis on the side beams, the fixture can achieve positioning of an upper cover, a lower cover and a vertical plate of the side beams during assembling, so that side beam deformation in the welding process is prevented, the purpose of quick and efficient assembly is achieved, the assembly quality of the side beams is ensured while the time is shortened, and the production rate is improved.

Description

technical field [0001] The invention relates to the technical field of manufacturing railway engineering vehicles, in particular to a rapid assembly and welding tool for the frame side beams of engineering vehicles. Background technique [0002] The side beam is the main part of the engineering vehicle frame and is currently the main product of the workshop. Its structure is composed of two vertical plates, upper and lower cover plates and multiple partitions. Many, large amount of welding, it is very easy to cause bending deformation of the whole side beam after welding, and in severe cases, distortion will occur, which will bring difficulties to the work of the subsequent process group or increase the workload of correction; at the same time, the side beams will be assembled The requirements for each size are relatively high. To mass-produce, it is necessary to design and manufacture tooling to ensure the quality of assembly and improve production efficiency. Contents of...
