The Improvement Of Welding Robot Control System Used On Manufacturing Of Subway

In modern transportation industry, rail transportation automotive, aerospace andincreasingly fierce competition. The rail transportation industry in the stainless steelcars with good fire safety, corrosion resistance, impact energy absorptioncharacteristics, low cost lightweight and maintenance, these advantages make itbecome an important direction of development of rail vehicles. With the developmentof resistance spot welding, resistance spot welding is widely used in the stainlesssteel body of the rail vehicle manufacturing, resistance spot welding member isassembled into the lap joint, and pressing between the two electrodes, througha current hot melt using the resistance of the base metal, the method of forming aresistance welding joints. With welding simple, low cost, high efficiency importantfeature. In my company metro vehicle body side wall in the manufacturing processchosen sided spot welding robot sidewall panels. My company is having an annualoutput of10billion yuan more than the size of large enterprises, but with the hugescale of production enterprises in stark contrast to the low level of automatedproduction lines, although to some extent on the use of a number of automaticwelding equipment, but in the workpiece clamping, handling and other aspects of theuse of the workpiece is completely artificial. According to the transformation of theexisting production line welding robot project experience, this article about how tostabilize "low cost, high efficiency " manufacturing philosophy and the quality of thewelding robot features combine to make a preliminary study. From the architectureand surrounding key supporting tooling departure control system, the welding robottooling and supporting organic combination, share a control system, which saves thecost and greatly improves production efficiency.This paper discusses the integration of supporting automatic application toolingand welding robot on the body welds. First, from the automatic chemicalcharacteristics of artificial bits and starting their research in the subway car body manufacturing process of the two stations rational allocation ratio.Secondly, the metro vehicle body side wall welding production line controlsystem analysis and design, the compression tooling, tooling raised through externalinterfaces and single-sided spot welding robot robot together, you can spot weldingrobot on the control panel, the command set, the pinch tooling along an XYZ axismovement, and the realization of the pressing operation, the tooling can be achievedin elevation and elevation of the Y-axis moving operation. The spot and pressedelevation fully automated, to ensure product quality, while greatly improvingproduction efficiency. The main contents include the following aspects: controlsystem design and analysis, design of electrical control systems, PLC control systemdesign, including the design and software components PLC system hardware design,PLC control system programming, PLC control system flowchart design, networkdesign and build production lines and so on.Finally, the production will yield production line automation of previouslymanual operation after the comparison, the automatic integration of fast, flexiblecontrol, high efficiency, and quality assurance. Production line automationtechnology for the realization of the transformation of the company high quality, highefficiency requirements, provides a new technical support.
