A kind of na1 type railway transport vehicle middle beam composition assembly device

Abstract

The invention relates to an NA1 type railway transport vehicle center sill component assembling device. the device comprises a middle center sill assembling jig and a center sill component assemblingjig; the middle center sill assembling jig comprises a jig base, a first fixing upright post, a second fixing upright post, an air pressure cylinder, a plane positioning block, a portal air pressure device and a variable-height horizontal supporting plate, wherein the first fixing upright post and the second fixing upright post are oppositely connected to the jig base in a fastening manner; the air pressure cylinder is connected to the first fixing upright post in the fastening manner; the plane positioning block is installed on the second fixing upright post; the portal air pressure device isarranged on the jig base in a crossing manner; the variable-height horizontal supporting plate is connected to the jig base between the first fixing upright post and the second fixing upright post inthe fastening manner; the center sill component assembling jig comprises a framework, a middle center sill fastening device and two draft sill fastening devices, wherein the middle center sill fastening device is arranged at the middle part of the framework; and the two draft sill fastening devices are fixedly arranged at the two ends of the framework in a manner of being longitudinally symmetricto the middle center sill fastening device. The NA1 type railway transport vehicle center sill component assembling device is simple in structure, reasonable in design, quite high in innovativeness and practical significance, and widely applied to assembling of NA1 type railway transport vehicle center sill components.

Description

technical field [0001] The invention relates to an assembling device for some components of a NA1 type special transport vehicle for trucks, in particular to an assembling device for the middle beam of a NA1 type railway transport vehicle. Background technique [0002] In recent years, the volume of railway freight has gradually increased, and the boundaries of transportation types have also continued to expand, making the demand for prototype models continue to increase. For example, the NA1 transport vehicle is a new model specially developed for railway transport trucks. The overall length of the NA1 transport vehicle is relatively long, and the center beam is the main load-bearing structure. The requirements are high, and the welding operation is difficult. However, due to the lack of relevant tooling equipment, the assembly of the center beam is time-consuming, laborious, and inefficient, and it is difficult to guarantee the quality of assembly and welding; Safety is...

AI Technical Summary

Problems solved by technology

The overall length of the NA1 transport vehicle is relatively long, and the center beam is the main load-bearing structure. High requirements and difficult welding operation

However, due to the lack of relevant tooling equipment, the assembly of the center beam is time-consuming, laborious, and inefficient, and it is difficult to guarantee the quality of assembly and welding; Safety is also difficult to guarantee

In the railway freight car manufacturing industry, welding tires are usually used to fix the size and shape of the connecting parts of the components, so as to meet the requirements of assembly accuracy and quality. However, there is no special assembly for the middle beam of NA1 type railway transport vehicles. Welding tire
