Abstract

Provided is a device for assembling a stainless steel vehicle body of a railway vehicle. The device comprises a side wall external positioning and internal propping device, a special chassis centering, positioning and clamping mechanical device and a specific track rocker arm type tension device, wherein through the side wall external positioning and internal propping device, a side wall is tightly attached to side wall positioning devices on walking boards on two sides in an external positioning mode by matching a horizontal oil cylinder, a first connecting block, a sliding seat, a linear guide track, a side wall external positioning piece and a side wall inner propping piece; a chassis of the vehicle body is symmetrically tensioned along a longitudinal center line of the vehicle body by the special chassis centering, positioning and clamping mechanical device through a drag hook, a tensioning lead screw and a gear transmission mechanism, so that the chassis can be automatically centered, positioned and tensioned when mounted; the chassis is placed on a supporting seat with a height and width adjustable function; and meanwhile, by the specific track rocker arm type automatic tension device, the chassis is tightly attached to the supporting seat. By the device, the vehicle body can be assembled quickly and accurately, and production efficiency and automation degree are high.

Description

technical field [0001] The invention belongs to the field of rail vehicle assembly, and in particular relates to a device for assembling a rail vehicle stainless steel body. Background technique [0002] The stainless steel car body assembly of traditional rail vehicles is assembled and positioned by struts inside the car body. The struts and the internal beams of the car body are fixed by manual MAG welding points or connected by positioning pins. way zip tight fit. This assembly method has the following disadvantages: (1) manual work is labor-intensive and the positioning accuracy of the car body is low; (2) manual MAG solder joints also affect the quality of car body manufacturing to a certain extent; The staggered setting affects the normal operation in the car, and even causes personal injury accidents; (4) low production efficiency. Contents of the invention [0003] The invention provides a rail vehicle stainless steel car body assembly device, which changes the t...
