With the popularization of intelligent production, the utilization rate of CNC machining center machine tools is getting higher and higher. And the current CNC machining center is gradually developed from the previous CNC milling machine, which combines the characteristics and functions of the CNC milling machine, upgrades on the basis of the original, increases the function and structure of the automatic tool changer, through the pre-placement of different tools, makes the CNC machining center in programming, can realize a variety of convenient and efficient processing technology, saves the time of machine tool shutdown and manual tool change, and the current automatic tool changer has a variety of tool magazines such as disc type, bucket hat type, chain type, etc., Today, we will introduce the automatic tool change structure process.
Five-axis machining center disc type tool magazine
The automatic tool changer of the CNC machining center, although there are disc type, hat type, chain type, etc., according to the power of the tool magazine rotation, it can be divided into hydraulic motor, ordinary motor, servo motor, cam machinery, non-power and other forms. Among them, the chain tool magazine is characterized by large capacity, more than 100 tools can be pre-placed, and the relative utilization rate of this tool magazine is low. The disc tool magazine is generally 24/32 tool capacity, which can meet the processing needs of the vast majority of production enterprises, the disc tool magazine tool change is a random tool change, this method is used in the case of more tools, the auxiliary tool change is carried out through the manipulator, there is no tool return process, the spindle moves to the safe tool change height when the tool is changed, the manipulator takes out the tool from the tool magazine, and then removes the tool from the spindle, the manipulator rotates 180 degrees to load the tool into the spindle, so that the tool change speed can be controlled within 3 or 5 seconds, and the tool change efficiency is extremely high, Therefore, the application rate of this automatic tool changer is relatively widespread.
Five-axis machining center bucket hat type tool magazine
The hat type tool change structure does not have a manipulator, which belongs to the fixed tool change method, which is generally used in the case of not many tools, and realizes the automatic tool change function through the mutual transmission between the spindle and the tool magazine. After each device is turned on, the tool magazine needs to be returned to zero and retrieved. When changing tools, the spindle moves to the tool magazine position, the spindle puts the tool back to the tool magazine, and then the tool magazine rotates to the new tool position that needs to be replaced, and the spindle grabs. These two actions cannot be performed at the same time, so the tool change speed will be slower.
Five-axis machining center chain tool magazine
The tool change methods and tool structures of chain tool magazine, disc tool magazine and bucket hat tool magazine are different, but for different processing industries and the configuration of different CNC machining center machine tools, the best choice can better meet the production needs of enterprises. After all, the existence of each automatic tool changer has its own advantages.
