Abstract

The invention discloses an automatic welding fixture of subway train obverse-reverse side roofs, comprising a base, an obverse side roof welding fixture body, and a reverse side roof welding fixture body, wherein the base is fixed on the ground and equipped with a connecting tenon on the top portion, the bottoms of the obverse side roof welding fixture body and the reverse side roof welding fixture body are both equipped with a connecting tenon groove which is matched with the connecting tenon, and the obverse side roof welding fixture body and the reverse side roof welding fixture body are both provided with a hoisting structure. A quick switch can be performed between the obverse side roof welding fixture body and the reverse side roof welding fixture body through a crown block, so that an automatic welding operation of the obverse side roof and the reverse side roof can be separately realized on the same automatic welding station and welding quality of roof components can also be ensured, overcoming the problem of insufficient flexibility in layout of the current subway train roof welding process and guaranteeing the project progress of roof welding.

Description

technical field [0001] The invention designs a welding tool, in particular an automatic welding jig for the front and back of the roof of a subway vehicle. Background technique [0002] At present, the welding operation of large parts of subway vehicles is completed by welding robots. Such welding robots are imported and expensive. It is most direct to use a welding robot to complete the front and back welding of parts within its limited track length. way to save costs. [0003] In the existing subway car roof welding process layout, there is an automatic welding station on both sides of the roof, and each station is a fixed fixture designed separately. Once the process layout changes, the transfer of these large fixtures is inevitable. Takes a considerable amount of time to complete. [0004] However, the production and delivery cycle of foreign welding robots is very long. When the project time is tight and a large number of welding robots are needed, only a part of the ...
