Framework side beam welding tool quick change device

Abstract

The invention discloses a framework side beam welding tool quick change device. The device comprises two connecting parts and a linear slide rail, wherein each connecting part comprises a connecting base for connecting with side beam welding tools, a lifting rotary tire turntable for driving the connecting base to rotate around a horizontal shaft, and a lifting rotary tire for driving the liftingrotary tire turntable to lift; the connecting base in each connecting part is fixedly connected to the lifting rotary tire turntable, and the lifting rotary tire turntable is rotationally connected tothe lifting rotary tire; the connecting base in one connecting part is opposite to the connecting base in the other connecting part; a slide base is arranged at the bottom of the lifting rotary tirein one connecting part, and is slidingly connected above the linear slide rail; and the other connecting part is arranged in a preset position in the extension direction of the linear slide rail. Theframework side beam welding tool quick change device realizes adjustment of the distance between the two connecting parts through arrangement of the linear slide rail and the slide base, and can change the framework side beam welding tools more safely, efficiently and quickly.

Description

technical field [0001] The invention relates to the technical field of tool quick change machinery, in particular to a frame side beam welding tool quick change device. Background technique [0002] With the rapid development of the track traction equipment manufacturing field, a large number of new high-speed EMUs, maglev trains, modern trams, modern trolleybuses, freight locomotives, intercity subways and other types of vehicles have appeared in large numbers. In order to reduce manufacturing costs, reduce waste of resources, and improve production efficiency, it is very necessary to realize collinear production of different models. [0003] The welding of the side beams of the bogie frame of all models is completed on the side beam welding tool. To realize the production of different models on the same line, the tooling of the welding station must be replaced. [0004] In the prior art, when replacing the side beam welding tooling, the operation steps are as follows: 1. ...

AI Technical Summary

Problems solved by technology

[0005] Since each time the tooling is changed, it is necessary to first loosen the 8 bolts and 8 anchor bolts on the left and right lift swivel turntables, and use the crane to hoist and weld the lift swivel, which will waste a lot of time. It takes time to disassemble the tooling and will reduce the efficiency of driving; every time the tooling is changed, it is necessary to re-embed the anchor bolts and pour the concrete, which will cause a waste of resources and increase the manufacturing cost, and there will be a long time after the concrete is poured. Curing cycle, affecting production efficiency
