Description
技术领域technical field

背景技术Background technique
近年来，我国电力需求增长迅速，电网的高速建设拉动了输变电设备的市场需求，特别是高速动车的大范围推广，变压器性能好坏直接影响到行车的安全。随着安全面临着严峻的考验，所以变压器特别是油浸式变压器的油箱是该产品的重要部件之一，高铁对于产品的尺寸要求越来越高，油箱焊接的密封性要求越来越高。如图1所示，油箱由底板一101、底板二102、箱壁一103、箱壁二104和箱盖组成，其中前四个部件的焊接和尺寸要求为整个箱体的关键工序。In recent years, my country's electricity demand has grown rapidly, and the high-speed construction of the power grid has stimulated the market demand for power transmission and transformation equipment, especially the large-scale promotion of high-speed trains. The performance of transformers directly affects the safety of driving. As safety is facing severe tests, the oil tank of transformers, especially oil-immersed transformers, is one of the important components of this product. High-speed railways have higher and higher requirements for the size of products, and higher and higher requirements for the sealing of oil tank welding. As shown in Figure 1, the fuel tank is composed of the first bottom plate 101, the second bottom plate 102, the first tank wall 103, the second tank wall 104 and the tank cover. The welding and size requirements of the first four parts are the key processes of the entire tank.
由于以往人工手动安装存在误差，导致油箱的一致性总是停留在一个阶段，无法继续提升；同时由于油箱的部件一般比较大比较重，人工移动、校准、压紧等工作量很大，工作效率低；并且由于客户个性化需求多，导致不同的产品都需要制作相应的组焊工装，导致工装成本高，利用率低，占地多，管理难度大等一系列问题。如何解决以上问题，并保证每个油箱的组装一致性、尺寸精度和提高操作者施行焊接效率以及预防变形措施，如何使油箱工装最大程度的做到通用化而降低设计和制造成本，最大限度提高市场竞争力也是企业发展的关键点。Due to errors in manual installation in the past, the consistency of the fuel tank always stays at a certain stage, and it cannot be further improved; at the same time, because the parts of the fuel tank are generally relatively large and heavy, the workload of manual movement, calibration, and compression is very large. Work efficiency Low; and due to the large number of individual needs of customers, different products need to make corresponding assembly and welding tools, resulting in a series of problems such as high cost of tooling, low utilization rate, large land occupation, and difficult management. How to solve the above problems, and ensure the assembly consistency and dimensional accuracy of each fuel tank, improve the operator's welding efficiency and prevent deformation measures, how to make the fuel tank tooling universal to the greatest extent, reduce design and manufacturing costs, and maximize Market competitiveness is also the key point of enterprise development.
