Aluminum alloy riveted subway vehicle side wall general assembly welding flexible chemical equipment

Abstract

The invention discloses an aluminum alloy riveting subway vehicle side wall total installing and welding flexible tool. The aluminum alloy riveting subway vehicle side wall total installing and welding flexible tool comprises at least two annular hand wheels. Two sets of side wall tool mechanisms are arranged between the annular hand wheels. The two tool mechanisms are symmetrically arranged in a front-and-back mode. Each side wall tool mechanism comprises an upper fixing plate, a lower fixing plate, a plurality of upper side beam clamps, lower side beam clamps corresponding to the upper side beams, and a beam locking device arranged between the upper side beam clamps and the lower side beam clamps. The upper fixing plates are parallel to the lower fixing plates. The upper side beam clamps are arranged on the upper fixing plates, the lower side beam clamps are arranged on the lower fixing plates, and the beam locking devices are connected between the upper fixing plates and the lower fixing plates through tool bases. The aluminum alloy riveting subway vehicle side wall total installing and welding flexible tool is suitable for side wall installing and welding of multiple items, the improvement cost is low, the period of the new item tool preparation is shortened, the tool occupied space is saved, the accuracy and consistency of the tool are guaranteed, the productivity is improved, and the flexibility of the tool is fully guaranteed.

Description

technical field [0001] The invention relates to an aluminum alloy riveted subway vehicle side wall general assembly welding flexible chemical equipment, which belongs to the technical field of rail transit. Background technique [0002] At present, there are many models of aluminum alloy riveted subway vehicles, and there are great differences in the side wall structure of different models, including the length of the side wall, the distribution of the door pillars of the side wall, and the deflection of the side wall. In the past, the side wall general assembly welding tooling used in riveting subway vehicle projects was designed and manufactured for specific projects and specific models. Every time a new project is launched, a whole set of assembly welding equipment needs to be remade. The existing tooling in the workshop cannot be used reasonably, and the new tooling also occupies the limited layout of the workshop. Moreover, the design and manufacture of a set of tooling...
