Abstract

The invention discloses a presetting and detecting device for vehicle deflections of metro vehicles, comprising a deflection presetting device and further comprising a horizontal deflection detecting device. The deflection presetting device comprises a hydraulic jack for jacking upwards the bottom of a vehicle body and a vehicle body supporting device; the vehicle body supporting device is provided with a jack support on which the hydraulic jack is arranged; and the vehicle body supporting device is further provided with a hydraulic pull-down device. The invention further comprises a method for presetting and detecting deflections by using the presetting and detecting device for vehicle deflections of metro vehicles. All processes of the method disclosed by the invention can be realized on one tire position of technical equipment, the process required to lift the vehicle body to detect the deflection is avoided after the vehicle body is produced by using an ordinary process, the technical route is shortened and the invested cost of the technical equipment is reduced; and at the same time, the investment of the work procedures is reduced, the work time is shortened and a win-win effect of technology and economy is achieved.

Description

technical field [0001] The invention relates to a multi-functional process equipment for assembly welding and detection of a car body assembly in the technical field of subway vehicle manufacturing, in particular to a device for presetting and detecting the deflection of a subway vehicle body, and a device using the above-mentioned overall deflection presetting of the subway vehicle body A method for preset deflection and deflection detection by setting and detecting device. Background technique [0002] Subway vehicle body assembly, in order to ensure that the rear body chassis of the assembly meets the design requirements of deflection, it is necessary to create a smooth upward curve deflection in the length direction of the vehicle body, and finally the vehicle body can be maintained after the vehicle body is installed and when it is loaded. Therefore, when the car body is produced, it is necessary to preset the deflection of the car body according to the rear deflection ...
