Abstract

The utility model relates to the technical field of B-type urban railway vehicle bogie frame welding tools, in particular to a universal B-type urban railway vehicle bogie frame welding auxiliary tool. The universal B-type urban railway vehicle bogie frame welding auxiliary tool comprises a supporting base, a plug pin seat, an adjustable plug pin, a positioning plate, two strip-shaped pressing plates, two bolt assemblies, a longitudinal pressing screw, a transverse pressing screw and a vertical supporting screw. The auxiliary tool has the beneficial effects that the auxiliary tool is used in the welding procedure of a B-type urban railway vehicle frame manipulator, different types of B-type urban railway vehicle frames can be rapidly switched on the same tool through the adjustable plug pin and the vertical supporting screw, the frame positioning precision is high, mounting and dismounting operation is convenient, thus the utilization efficiency of the manipulator is improved, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to the technical field of welding tooling for the bogie frame of a B-type urban railway car, in particular to a general-purpose auxiliary tooling for welding the bogie frame of a B-type urban railway car. Background technique [0002] With the continuous popularization and application of welding manipulators, most of the welding seams such as side beam composition and beam composition of bogies such as railway passenger cars, urban rail passenger cars and light rails are carried out on manipulators. However, due to the differences in the dimensions of the bogie frames of different types of B-type urban railway cars, it is often necessary to manufacture different types of special tooling. The frame welding tooling for the same platform is not universal, which not only increases the cost of the tooling, but also leads to frequent loading and unloading of the tooling during the production process, which affects production efficiency....
