Research On The Optimization Process And Support Technology Of Excavator's Boom

Through the analysis of the first half of the sales forecast and nearly three years of excavator,we know that the competition of domestic excavator brand is more and more intense and the requirements of domestic excavator OEM quality and delivery is more and more high.As an important component of digging machine,the boom suffers alternating load repeatedly in the process of excavator working.Then it becomes to be not only parts of the structure where problem is most likely to occur,but also the benchmarking to measure the manufacturing capacity of excavator manufacturing enterprise.The quality of the project's boom is also a measure of quality reliability of excavator.How do the enterprises in the existing process equipment improve the welding quality and control the boom boom welding deformation and improve the machining efficiency of the boom is one of the most important topics in the existing enterprises.Therefore,this paper focuses on solving the problems above,to find the assurance of the manufacturing process technology boom through the key technology of process control.First the composition of excavator and important components are intrduced,and key parts of excavator boom process,product structure,high quality welding requirements and high precision machining requirements are described.The welding deformation and welding requirements,the process requires frequent knife test and so on are also introduced in the process of manufacturing boom.Followed by the introduction of the boom to the welding process of critical control points.The main process of boom welding equipment and process are described,and the side plate welding process test was carried out in-depth investigation and research.The boom assembly procedure of process equipment and process sequence are described.The boom robot welding process mainly from robot welding equipment research and development of welding sequence in detail.The artificial boom welding process in the welding deformation data collection and analysis carried out a detailed study of the key position of welding.Finally,introduced the application in online measurement technology boom processing,measurement and calculation of macro program by Renishaw head,is the boom machine online measurement processing,improve work efficiency and product quality.And the machining process improvement are described,the introduction of non-standard tools,design of special machining equipment,optimization of cutting parameters to ensure machining efficiency,reduce processing costs.Through the dynamic security technology research boom of key processes,improve the welding quality and control the boom boom of the welding deformation and improve the machining efficiency of the boom.
