工业机器人在航空航天领域的应用实例

浏览量
  如今,航空航天领域在大型零件上实现精度和刚性的任务,都要由工业机器人来完成。因为飞机计划的使用期限为10到30年,因此简单组装任务的回报可能非常有益。接下来让我们一起来了解下工业机器人在航空航天领域都有哪些应用。
  Nowadays, the task of achieving precision and rigidity on large parts in the field of aerospace must be completed by industrial robots. Since the aircraft is planned to last 10 to 30 years, the payoff from simple assembly tasks can be very beneficial. Next, let\'s learn about the applications of industrial robots in the field of aerospace.
  1.钻孔和紧固Drilling and fastening
  这是航空航天工业中使用机器人技术的最大区域。实际上,手动钻孔需要分三个不同的步骤进行:先导孔钻孔,最终尺寸钻孔和铰孔。此外,手动钻孔机需要使用大而复杂的夹具,以及功能强大的工具才能在钛等异质材料中执行这些钻孔步骤。通过使用工业机器人,无需设计特定的夹具-机器人使用视觉系统在所需位置钻孔。另外,钻孔步骤可以单次执行。当人们一次完成工作时,机器人可以节省大量时间。
  This is the largest area in the aerospace industry where robotics is used. In fact, manual drilling requires three different steps: pilot hole drilling, final dimension drilling and reaming. In addition, manual drilling machines require large and complex fixtures and powerful tools to perform these drilling steps in heterogeneous materials such as titanium. By using an industrial robot, there is no need to design a specific fixture - the robot uses a vision system to drill holes in the desired location. In addition, drilling steps can be performed in a single run. Robots can save a lot of time when people finish their work at once.

  2.检验Inspection
  任何飞机制造过程中的检查过程都是至关重要的,并且飞机的检查要求很高。机器人可以执行多种检查程序。在某些情况下,末端执行器配有激光扫描仪和测量探针。钻孔操作后,使用计量设备,然后通过激光扫描仪观察该孔,该激光扫描仪可以收集不同的信息。
  The inspection process in any aircraft manufacturing process is very important, and the aircraft inspection requirements are very high. Robots can perform a variety of inspection procedures. In some cases, the end effector is equipped with a laser scanner and a measuring probe. After the drilling operation, metering equipment is used and the hole is observed through a laser scanner, which can collect different information.
  3.焊接Welding
  即使复合零件在飞机上越来越受欢迎,金属零件在某些应用中仍然占有一席之地。实际上,组装中的金属零件焊接(例如涡轮机)需要精确进行。在电动机中使用诸如钛和镍合金之类的稀有金属时,工业机器人是必不可少的,以便进行有效而准确的焊接。当谈到航空航天应用中的机器人焊接时,可重复性,刚度和严格的公差实现是主要论据。
  Even though composite parts are becoming more and more popular in aircraft, metal parts still have a place in some applications. In fact, welding of metal parts in assembly (e.g. turbines) requires precision. When rare metals such as titanium and nickel alloys are used in motors, industrial robots are essential for effective and accurate welding. When it comes to robotic welding in aerospace applications, repeatability, stiffness and strict tolerance implementation are the main arguments.
  4.密封和分配Sealing and distribution
  由于部件的尺寸,对于手动操作者来说,在大型机身或框架部件上施加密封剂,油漆,金属和陶瓷涂层是困难的。这就是为什么将机器人用于此类应用的原因之一。通过将机械臂放在轨道上,工作单元可以覆盖30到40英尺的距离,并有几层楼高。航空航天公司倾向于使用更多的机器人方法,包括从小型到大型点胶应用程序。
  Due to the size of the components, it is difficult for manual operators to apply sealer, paint, metal and ceramic coatings on large fuselage or frame components. This is one of the reasons why robots are used in such applications. By placing the robotic arm on the track, the work unit can cover a distance of 30 to 40 feet and be several stories high. Aerospace companies tend to use more robotic methods, from small to large dispensing applications.
  5.刚性制造Rigid manufacturing
  刚性不是应用程序本身,但是在航空航天制造中使用机器人时,可以认为刚性是一种优势。实际上,多年来,机器人比以往任何时候都趋向于更加精确。但是,由于具有严格的公差,可重复性要求和精确的制造工艺,因此机器人必须更加精确。这就是为什么大多数飞机制造商都使用辅助编码器的原因。换句话说,他们不信任机器人关节中的原始编码器。植入机器人后,集成商会安装辅助编码器,以准确知道机器人关节的位置。
  Rigidity is not the application itself, but rigidity can be considered an advantage when robots are used in aerospace manufacturing. In fact, over the years, robots have tended to be more accurate than ever before. However, due to strict tolerances, repeatability requirements and precise manufacturing processes, robots must be more accurate. This is why most aircraft manufacturers use auxiliary encoders. In other words, they don\'t trust the original encoder in the robot\'s joints. After the robot is implanted, the integrator will install an auxiliary encoder to accurately know the position of the robot joint.
  航空航天领域对于设备的制造以及检测有着非常严格的要求,而工业机器人先进的技术应用、制造理念和管理规划等加速了航天航空领域的发展。
  Aerospace industry has very strict requirements for equipment manufacturing and testing, and the advanced technology application, manufacturing concept and management planning of industrial robots accelerate the development of aerospace industry.
