The form and difference of milling machine 850 tool magazine:
There are two types of tool magazines for CNC machining centers, one is the manipulator disc tool magazine, and the other is the hat tool magazine. The function of the tool magazine of the machining center is mainly used to store tools, and it is one of the main components in the automatic tool changer. According to the number of tools in the tool stock and the way of taking the tools, the tool magazine can be designed into different types. The tool change process of the machining center machine tool is more complicated. When using the machining center to process parts, the different types of tools that need to be used during the machining process must be installed in the tool sleeves in the tool magazine, and the size is pre-adjusted outside the machine. , Put it into the tool magazine in a certain way. When the machining center is processing the tool change, the tool is selected in the tool magazine first, and the tool is taken out from the tool magazine and the spindle by the tool change device. After the tool exchange, load the new tool into the spindle and put the old tool back into the tool magazine. The tool magazine for storing knives generally can hold 16 knives or 24 knives. What is the difference between the common hat tool magazine and the disc tool magazine? This article gives a detailed introduction.
Hat tool magazine: The tool change method of this tool magazine is to change the tool by moving the spindle up and down. When the tool on the spindle enters the card slot of the tool magazine, the spindle moves upward and away from the tool, and the tool magazine rotates. When the tool to be changed is aligned directly below the spindle, the spindle moves down so that the tool enters the spindle taper hole. After clamping the tool, the tool magazine returns to its original position.
Advantages: This type of tool magazine has a simple structure, low requirements on the surrounding environment, low failure rate and affordable price.
Disadvantages: Long tool change time and low efficiency. Affect the working stroke of the spindle of the machining center.
The disc tool magazine is also called the manipulator tool magazine.
Disc-type tool magazine: the use of robotic arms for automatic tool change has obvious advantages and fast tool change speed. The working principle is that the mechanical arm simultaneously pulls out the tools in the tool magazine and rotates 180° on the spindle and inserts the tools at the same time.
Advantages: Fast tool change speed. The machine tool has relatively high processing efficiency.
Disadvantages: The failure rate is relatively high, and the requirements for the surrounding environment are high.
Such as air pressure, knife release action, and knife release signal. A common failure situation is that the tool is pulled out before the release claw is fully opened, which will cause damage to the spindle, mechanical arm, and cam.
In fact, through comparison, we can see that the higher the degree of automation or the easier to use, the more complex things are, and the more complex things are more prone to failure.
