A tool magazine control system and its control method

Abstract

The invention discloses a tool magazine control system and a control method thereof, which includes: a tool magazine, the knife magazine has a plurality of knife cups, and each of the knife cups is used to accommodate a tool; a knife arm, the The knife arm is used to pick and place the tool from the tool magazine and replace the tool on the main shaft; the control unit is used to control the rotation of the tool magazine so that the knife cup corresponds to the knife arm, controlling the rotation of the knife arm to transfer the tool from the main shaft to be accommodated in the knife cup of the tool magazine or to be transferred from the knife cup of the tool magazine to a tool mounted on the main shaft superior. Adjust the tool magazine speed, tool arm speed and arrange the position of the tool in the tool magazine through the tool weight information to reduce the unbalanced load of the tool magazine, thereby improving the tool change efficiency of the tool magazine and the service life of the tool magazine. Accordingly, the workpiece has a good surface quality during the finishing process.

Description

technical field [0001] The invention relates to the technical field of tool change in a machine tool magazine, in particular to a tool magazine control system and a control method thereof. Background technique [0002] The tool magazine system of a machine tool (that is, a machine tool or a machine tool) is a device for storing and changing tools during processing. Since this tool magazine system can store multiple tools at one time, and can correctly select the tool according to the program control, during the processing, the next preset tool to be used is stored in advance, and then used when it is needed Tool exchange: Compared with the manual tool change method in the prior art, it can greatly reduce manpower and shorten processing time. [0003] According to different electric control configurations, the tool system can be divided into two types: non-servo tool magazine and servo tool magazine. The tool preparation process used by non-servo tool magazines is as follow...

Problems solved by technology

[0008] Step S108: The variable frequency motor stops running; however, the disadvantage of this type of tool magazine is that the variable frequency motor can only rotate at a fixed speed, which cannot achieve the optimal tool preparation speed; another disadvantage is that it is easy to use external I / O devices There is a problem of damage, which in turn causes the tool magazine mechanism to be easily damaged

[0012] In addition, if the machine is performing precision machining (subsequently collectively referred to as finishing), if the tool magazine performs the tool preparation action, the rotation of the tool magazine will cause the machine to vibrate, and may also cause poor machining effects on the surface of the workpiece. good

Therefore, under the premise of not affecting the processing effect of the workpiece, the motion planning of the tool magazine rotation will have other restrictions, and it will be carried out more conservatively, which ultimately makes the rotation speed planning of a single group of tool magazines impossible. Satisfy the needs of various situations, and then affect the processing efficiency
