| 摘要：刀库是自动换刀装置中最主要的部件之一，其容量、布局以及具体结构对加工中心的设计有很大影响。 16刀刀库是在小型加工中心应用最为广泛，根据使用的场合和实际运用的要求，设计了相应的16刀的圆盘式刀库，并且对它的控制进行了一定的研究。 论文首先对16刀刀库总体设计方案进行阐述，阐述其各部件的工作原理，然后就刀库的结构设计与控制分章节对各个部分进行计算与设计。 以刀库的结构设计为研究的重点，本论文完成的是盘式刀库的总体设计、传动设计、结构设计以及传动部分的运动和动力设计。这种刀库在数控加工中心上应用非常广泛，其换刀过程简单，换刀时间短，定位精度高；总体结构简单、紧凑，动作准确可靠；文护方便，成本低。本刀库减速传动部分分两级减速，一级传动部分采用齿轮减速装置，二级传动部分采用蜗轮蜗杆减速装置，此种设计方案可提高输出轴的传动平稳性能，即提高刀盘的运转平稳性。其中传动部分为蜗杆蜗轮的一种减速装置，对于该装置中的蜗杆、蜗轮以及相关的轴都进行了详细的计算;控制部分为刀库送刀部分，由气动液压控制和PLC控制完成。27745 毕业论文关键词：加工中心，刀库，蜗杆蜗轮，气压，PLC。 CNC machining center disc tools library design Abstract：Tool storage is one of the main components of the automatically-trading-knife installment. Its capacity, position and structure have great influence to the design of the machining centre. 16-tool tool storage is widely used in the machining centre. Based on the situation and requirement the 16-tool used, the disc-style tool storage of the 16-tool is designed and some research about its control is made in this paper. The paper illustrates the design project of the 16-tool tool storage firstly, and then explains its operation principle, and at last calculates and designs the structure and control of the tool storage separately by chapters. This paper completed the overall design, transmission design, structure design and the transmission part's movement and dynamic design of the disc tool house. Such a tool house in the CNC Machining Center is widely used, the tool change is simple, tool change time is short, high-precision positioning; overall structure is simple and compact. Action is accurate and reliable; convenient maintenance and low cost. The slowdown part in the transmission of the tool house includes two parts, the first part of the transmission is gear deceleration device, the second transmission part of the transmission is Worm Gear deceleration device, such design can increase the output shaft of the transmission smooth performance, improve the smooth functioning of the tool house. The sizes of the worm, worm gear and axis are calculated. The control parts are tool storage delivering parts, which is completed by the hydraulic pressure and PLC control.
