如果您在机器人钻探的最终执行器的市场上，很难知道要选择哪种工具。
Is robot drilling the same as any other type of drilling when it comes to purchasing a tool?
Or are there are extra properties you need to be aware of?
Robot drilling is a relatively simple activity. You just need a bit of basic knowledge to find the right end effector for you.
钻孔主轴：选择的工具
Your options for drilling end effectors are relatively straightforward. If you want to drill with a robot, you likely need a drilling spindle.
钻孔主轴直接适合机器人的手腕。它保持钻头并提供必要的扭矩和速度钻孔。机器人只需将主轴固定在材料上就位。
How a Drilling Spindle Works
你可以想到钻孔主轴，就像手持式电钻一样。与具有大电动机和驱动带提供高扭矩的静电柱钻，钻孔主轴紧凑。一切都包含在主轴范围内。
然而，这并不意味着该工具必须比其他钻井工具更强大。例如，Teknomotor C31 / 40-C加工主轴，包括在内in the RoboDK libraryhas 700W power. This is double the power of many home pillar drills.
Finding the Right Robotic Spindle for Your Task
哪个钻孔主轴最好？
The answer depends on the needs of your specific task. You will need to assess a few properties when comparing the different robotic spindles available on the market.
Factors that affect your choice of spindle include:
- The robot model you are using.
- 你正在钻井的材料。
- The speed and force required for this drilling task.
There area few tips you can followto get the most accurate robotic drilling, such as ensuring that the robot has the required stiffness to complete the drilling task.
Drilling vs Machining Spindles
您可能看到的另一种类型的机器人主轴是加工主轴。这些非常类似于钻孔锭子。主要区别在于加工主轴在钻孔主轴仅支撑轴向载荷时支持轴向和径向载荷。
如果你正在考虑尝试robotic machining,it could be worth investing in a machining spindle for both drilling and machining.
7 Properties to Look for in a Robot Drilling End Effector
当您正在寻找钻孔末端效应器时，您应该优先考虑哪些功能？
与其他机器人工具相比，钻孔主轴合理简单。即便如此，有几个属性that you will want to consider when looking for the right spindle for you.
七个常见属性是：
1. Lightweight
机器人钻孔和其他类型的CNC钻孔之间的主要区别是重量限制。
Robots have a limited payload capacity that influences the amount of force the robot can apply to a surface. If you choose a heavy drilling spindle, this may reduce the amount of force that the robot can apply when drilling, depending on the orientation of the end effector at the time.
2. Cooling
Drilling tools get hot. There are various cooling systems you can use to reduce the heat of the tool when it is operating.
Examples of cooling systems include air convection, air vortex (which uses compressed air to generate supercooled air), liquid, and fans.
3. Mounting Options
You need to be able to fix your drilling spindle to the end of your robot arm.
If there is no mounting option for your robot model, you can likely still use the drilling spindle. You will just need to manufacture your own mounting plate to connect the spindle to the wrist of the robot.
4.电力系统
Drilling spindles are often electrically driven. However, there are also pneumatic and hydraulic drilling spindles available on the market.
Bear in mind that you may need to purchase an extra power system for your end effector if you don’t have a suitable one already available.
5. Spinning Speed
The speed of your drilling spindle will influence how quickly it will drill through a particular material and there are a fewdifferent formulas used to calculate this.
Spindles come with a wide range of speeds from 0 RPM to 30,000 RPM or more.
6.力量或力量
The power or force of the drilling spindle will influence the type of material that it can be used to drill. For instance, drilling titanium will require ahigher power toolthan drilling soft aluminum.
中指定的权力通常是何鸿燊rsepower or watts.
7.工具选项
The “business end” of any machining spindle is the drill bit that you attach to it. You need to ensure that your spindle supports the drill bits that you want to use and vice versa.
Common tooling options include a standard collet (as seen on a pillar drill), pneumatic fitting, and automatic tool changers.
A Useful Tip for Programming Your Robot Drilling Spindle
What do you need to remember when you are programming your drilling robot?
Firstly, it’s a good idea to use a programming interface that is designed for robot machining and drilling. For example,RoboDKcomes with a machining wizard that allows you to add machining and drilling paths quickly and easily.
A useful tip for programming is to remember that calibration is vital. When you are drilling manually, you can see the tip of the drill bit. This makes it very easy for you to adjust to changes in the bit position.
通过机器人，您将知道钻头位的唯一方法是正确的calibrate the robotwhenever you change the tool.
