Auxiliary device for mass positioning of chutes on subway steel car body doors

Abstract

The invention discloses a batch positioning auxiliary device for sliding grooves formed in a door of a subway steel vehicle body and belongs to the field of steel structure welding of stainless steel vehicle bodies of railway vehicles. According to the batch positioning auxiliary device for the sliding grooves formed in the door of the subway steel vehicle body, the three-dimensional positioning of heights, gaps and planar gradients for C-shaped horizontal sliding groove arrays is achieved by arranging a plurality of C-shaped sliding groove locking blocks on a horizontal positioning cross beam of a height positioning support. The positioning method of the batch positioning auxiliary device is simple, quick, convenient, accurate, reliable, and capable of reducing the repair rate and relieving the labor intensity greatly, and significantly improving the production efficiency of the working procedure. Besides, the batch positioning auxiliary device has the advantages of being simple in structure, practical, convenient to operate, low in cost, convenient to popularize and the like.

Description

technical field [0001] The invention belongs to the field of rail vehicle stainless steel car body steel structure welding, and in particular relates to a batch positioning auxiliary device for a chute on a door of a subway steel car body. Background technique [0002] Such as Figure 1 to Figure 3 As shown, a plurality of chute fixing seats 2 are usually arranged along the horizontal direction on the door frame beam 1 of the sliding door of rail vehicles such as subways, and each chute fixing seat 2 includes a horizontal long boss 2-1 and a horizontal short boss 2-2, two C-shaped horizontal chutes 3 are respectively welded and fixedly connected to the outer end surfaces of the horizontal long boss 2-1 and the horizontal short boss 2-2. The C-shaped horizontal chutes 3 fixed on the multiple horizontal long bosses 2-1 at the same height jointly form the first horizontal chute array, which is located on the multiple horizontal long bosses 2-1 at another height The respective ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the requirements of the new chute array positioning process, when the height, spacing and plane gradient of the two sets of horizontal chute arrays are measured, positioned and welded in three-dimensional space on the vertical sliding door steel structure door frame, Its positioning accuracy is poor, the repair rate is high, and the labor intensity is high, which seriously affects the technical problems of production efficiency. The invention provides a batch positioning auxiliary device for the chute on the door of the subway steel car body
