AI Technical Summary

Technical Problem

The existing bogie production line has low automation level, resulting in large labor investment and low production efficiency.

Method used

An automated bogie production line is designed, including a rocker side frame inspection line, a pillow frame spray line and a transition vehicle. The rocker and side frame are assembled into a pillow frame through a rocker side frame combination machine, and transferred to the spray line through the transition vehicle to achieve the overall spraying of the pillow frame.

Benefits of technology

The site occupation when spraying paint on a single-piece pillow and side frame is reduced, the spraying efficiency and effect is improved, and by reducing the use of a trolley, manpower investment is reduced and overall production efficiency is improved.

Abstract

The utility model provides an automatic bogie production line, and relates to the technical field of railway vehicles. The automatic bogie production line comprises a swing bolster and side frame maintenance line, a bolster frame spraying line and a first transition vehicle. The swing bolster and side frame maintenance line comprises a swing bolster and side frame combination machine used for assembling a swing bolster and a side frame into a bolster frame. The first transition trolley is used for moving between the lower line end of the swing bolster side frame combination machine and the upper line end of the bolster frame spraying line in a reciprocating mode so that the bolster frame can be transferred to the bolster frame spraying line. Under the condition that paint is not sprayed, the swing bolster and the side frame are assembled firstly, so that the situation that a single swing bolster and a single side frame are subjected to paint spraying to cause site occupation or poor accessory drying station quality caused by insufficient site area can be reduced, the spraying efficiency is improved, the first transition trolley can reduce the use of crown blocks under the condition that the bolster frame does not fall to the ground for production, and the production cost is reduced. And therefore, the production efficiency of the bogie is improved.
