轨道打磨机构设计(含CAD图)(外文翻译,论文说明书17000字,CAD图4张)
摘 要
本文根据国内外现有轨道打磨机技术和企业实际需求设计出一种不同于传统轨道打磨机构的创新性轨道打磨机构,该机构的设计灵感来自于装备制造业中的数控铣床,把铣床的工作原理运用到轨道打磨上来,改善原有产品在环保性和经济性。由于本次毕业设计的时间有限,根据企业指导技术人员的建议,我主要进行轨道打磨机构的进给机构的设计与三维建模,轨道打磨机构的打磨刀头部分设定为已知。
本次设计的创新点在于把传统的磨头式打磨改变为铣刀铣磨与磨头打磨相结合的方式,进给机构由传统的液压驱动变为电机与液压分别驱动。结构部分借用机床工作台的设计原理,在保证打磨机构的结构强度,刚度,稳定性和运行精度的前提下,尽可能的减轻结构自重。轨道打磨机构的结构设计参照有关设计手册和已有产品设计说明书。

Abstract
According to the existing rail grinding machine technology and the actual needs of enterprises at home and abroad, this paper designs an innovative rail grinding mechanism which is different from the traditional rail grinding mechanism. the design inspiration of this mechanism comes from the CNC milling machine in the equipment manufacturing industry. the working principle of the milling machine is applied to the rail grinding to improve the environmental protection and economy of the original products. Because the graduation design time is limited, according to the enterprise guide technical personnel's suggestion, I mainly to track grinding mechanism of feed mechanism design and three-dimensional modeling, track grinding mechanism of grinding head part set to known.
The innovation of this design is to change the traditional grinding head type grinding into the way of combining milling cutter grinding and grinding head grinding. the feed mechanism is changed from the traditional hydraulic drive to the motor and hydraulic drive respectively. The structure part borrows the design principle of the machine tool worktable, and lightens the self-weight of the structure as much as possible on the premise of ensuring the structural strength, rigidity, stability and operation precision of the grinding mechanism. The structural design of the track grinding mechanism shall refer to the relevant design manual and the existing product design manual.
