The draw equipment of the passenger car is used for the heavy-duty equipment that side skin and skeleton of passenger train assemble, it is one of the key equipment welded on the passenger car skeleton after drawing the side skin. Draw system taking hydraulic pressure as power machinery draw equipment , by basic track , draw shelf , is it act personally to draw and hydraulic pressure system make up. This system is used in many kinds of style, many kinds of craft, structure advanced mechanized degree high advanced skin assembly system, adopt this equipment can improve car body cover with hide draw quality , raise working efficiency by a large margin, lighten worker's labour intensity.
The draw machine equipment that this thesis designed is a set of intact draw systems, as important component of equipment of drawing etc., draw quality direct relation designed to act personally reach skin draw quality of quality, draw and act personally and hoist or lower the device mainly, clamp the device , push and lean against the device , four parts are formed to draw the device. The thesis is right to draw in machinery , push away and depend on , clamp, three devices of structure and function have made a throughgoing and painstaking analysis, has calculated and checked relevant structure; Have chosen some components in hydraulic pressure, has drawn the principle picture of the hydraulic pressure, and has made brief illustration to its movement course; Go up and down with the programming realization of PLC in the electric respect, draw , push away and depend on, clamp movement circulation. Thesis this probe into for relevant personnel , passenger car of producer skin draw question offer reference, can use for person who draw design of equipment make and produce directly.
