【摘要】：随着大型工程装备的使用范围越来越广泛,尤其是海洋工程施工起重作业工程船舶,单机吊装最大重量已达8000吨,大型船舶吊机和单点系泊装置等海工装备均设计有回转机构装配法兰面,构件外形尺寸如长度、高度、直径等通常都在3~8米,最大的可达10多米,已无法使用一般通用机床进行装配法兰面的机械加工,并且这些大型构件对加工精度要求较高,现场的打磨、焊割已经不能满足生产精度要求,必须采用专用的现场加工设备,才能满足行业的技术要求。所以,在这种情况下,人们开始进行反向思维,设计研发一种能够将机床安装到大型尺寸零件上进行加工的机床,这样就能够在现场对零件进行加工,节约了大量的经济成本和资源。在这种情况下,本文设计了一种模块化现场加工机床,能够在现场对大型法兰平面进行铣削和钻孔加工。通过对现场加工机床的了解,提出机床的设计方案,对机床采用模块化设计;对铣削和钻孔时切削力等参数进行计算;对机床进行模块化设计,并以所设计的结构为基础使用ANSYS对结构进行有限元分析,检验所设计的机床结构是否合理。
[Abstract]:With the wide use of large-scale engineering equipment, especially the marine engineering construction hoisting engineering ship, the maximum lifting weight of a single machine has reached 8000 tons. Marine engineering equipment such as large ship crane and single point mooring device are designed with rotary mechanism assembly flange face. The external dimensions of components such as length, height and diameter are usually 3 ~ 8 meters, and the maximum can be more than 10 meters. General machine tools can not be used to assemble flange surface machining, and these large components require high machining accuracy, the field grinding, welding and cutting can not meet the production accuracy requirements. Must use special field processing equipment, can meet the technical requirements of the industry. Therefore, in this case, people began to reverse thinking. Design and development of a machine tool can be installed on large size parts for processing, so that the parts can be processed in the field, saving a lot of economic costs and resources. In this case. In this paper, a modular field machining machine tool is designed, which can milling and drilling the flange plane in the field. Through the understanding of the field machining machine tool, the design scheme of the machine tool is put forward. Modular design for machine tools; The cutting force of milling and drilling is calculated. The modular design of the machine tool is carried out, and the finite element analysis of the structure is carried out with ANSYS on the basis of the designed structure to verify whether the structure of the machine tool designed is reasonable or not.
