B690型牛头刨床的液压及控制系统设计
摘要
牛头刨床的应用十分广泛，一般行业包括模具行业、汽车行业，高精尖行业包括航空航天、军事装备等方面。由于我国经济的快速发展，也使牛头刨床等机床持续有较大的需求，同时我国政府提出了2025计划，这也说明在宏观政策下，牛头刨床以及整个机床行业都是大有可为的，虽然我们在向数字化智能化迈进，但在现阶段以及相当长的一段时间内，普通机床例如牛头刨床等仍然会发挥巨大作用。所以对牛头刨床进行深入研究并掌握相关的知识是十分有必要的。
本次设计的主要内容包括三部分内容。第一部分主要是对机械部分的结构及功能的简单介绍以。第二部分是液压系统，B690牛头刨床的传动系统不同于以往的机械传动，采用的是液压传动，用于加工大型零件。它可以实现无极变速，优势明显，在第二部分对液压系统的原理以及主要工作回路进行了分析，并用软件绘制了系统原理图以及调速结构原理图。在第三部分，主要完成的是机电部分的控制，对于机床来说，机械部分以及液压部分相对来说是比较稳定的，所以机床能否运行在最佳状态即取决于电气控制系统的控制方式。而此次采取的PLC控制，能够实现开关逻辑控制和变频电动机的转速控制，在很大程度上可以提高刨床的效率和加工精度，加强刨床的可靠性和稳定性。同时PLC具有可靠性高、功耗低、维修方便成本低等诸多优势，从而可以达到减少投资、降低功耗等目的。
通过此次的设计，不仅对大学四年所学知识进行了总结回顾，而且将自己所学理论和实践相结合，不管是对自己个人能力的提升或者是职业的发展，帮助都是十分巨大的。

ABSTRACT
shaper is widely used, the general industry, including the mold industry, the automotive industry, high-tech industries, including aerospace, military equipment and so on. As a result of the rapid development of China's economy, but also to make a small planer and other machine tools continue to have a greater demand, while my government put forward the 2025 plan, which also shows that under the macro policy, the planer and the machine tool industry is promising, To the digital intelligent forward, but at this stage and for a long period of time, ordinary machine tools such as the black planer will still play a huge role. So it is necessary to thoroughly study and master the relevant knowledge of the planer.
The main contents of this design include three major aspects. The first part is a brief introduction to the structure and function of the mechanical part and the selection of the cutter head of the bulldozer. At the same time, a brief analysis is made on the typical parts of the Noah planer. The second part is the hydraulic system, because the B690 Tau planer transmission system is different from the previous mechanical transmission, the use of hydraulic transmission, so you can achieve stepless speed, obvious advantages, in the second part of the hydraulic system principle and the main working circuit Analysis, and software used to draw the system schematics and speed structure schematic. In the third part, the main part is the control of the electromechanical part. For the machine, the mechanical part and the hydraulic part are relatively stable. Therefore, whether the machine can run in the best condition depends on the control mode of the electrical control system The The PLC control, to achieve the switch logic control and inverter motor speed control, to a large extent can improve the efficiency of planer and machining accuracy, and strengthen the stability and stability of planer. At the same time PLC has high reliability, low power consumption, easy maintenance and low cost and many other advantages, which can reduce investment, reduce power consumption and other purposes. This is the graduation design of the three main aspects.
I believe that this graduation design, not only the four years of university knowledge of the summary of the review, it is a meaningful exploration, it let me learn their own theory and practice combined, whether it is their own personal ability Promotion or career development, help is very great
