Modularized adjustable passenger train end wall assembling and welding table

Abstract

The invention discloses a modularized adjustable passenger train end wall assembling and welding table. The table comprises a bottom frame, a short working table, long working tables and a door sill positioning assembly, wherein the short working table is fixed with the bottom frame; the long working tables are distributed on the two sides of the short working table; the door sill positioning assembly is fixed on the bottom frame at the remote end of the short working table by bolts; a door frame positioning assembly is fixed on the inner side of the long working tables by the bolts; positioning strips are fixed on the bottom frame on the outer side of the long working tables by the bolts; the distance between the inner side edges of the positioning strips is equal to the width of the passenger train end wall; and the distance between the outer end faces of the door frame positioning assembly is equal to the width of a door frame of the passenger train end wall. The end walls of different types of passenger trains can be produced by only replacing the door sill positioning assemblies, the door frame positioning assemblies and the positioning strips, which have different sizes. The end wall assembling and welding table solves the problems of various dimensional changes of end wall width direction and end wall door by replacing a small number of different modules and adjusting the positioning size of a small number of parts on the premise of ensuring reliable tool use, economy and convenience.

Description

technical field

[0001] The invention relates to a modularized and adjustable end wall assembly welding tool, which belongs to the technical field of railway vehicle manufacturing technology. Background technique

[0002] With the breakthrough of the company's passenger car products in the international market, more and more products that are completely different from the original domestic 25-type passenger cars have appeared, but the number is small (for example: Georgian cars, Malaysian cars, etc.), in the steel structure production Among them, if large-scale assembly welding tools are made for each product, it will not only increase the cost, but also affect the delivery time. Under the market economy, whether it can meet market demand with high quality, multiple varieties, small batches and low cost, and whether it can update products quickly is the key to an enterprise's invincible position in market competition.
