Embodiment Construction

[0026] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0027] A tool change control method for a servo tool magazine, used for tool change on spindle 1, such as figure 1 As shown, a knife arm 2 is provided on one side of the main shaft 1, and a tool magazine 3 is provided on one side of the knife arm 2. Part 21, the knife arm 2 is driven to rotate by the servo drive motor 4, a tool is connected to the main shaft 1 and the knife is punched or pulled by the knife punching cylinder 5; the servo tool magazine tool change control method includes the following steps:

[0028] Knife buckle: The servo drive motor 4 rotates the knife arm 2 to the first position according to the set length of the knife buckle pulse, so tha...

Abstract

The invention relates to a servo tool magazine tool changing control method. During the rotating process of a tool arm, a tool is loosened and broached in advance, so that the waiting time after the tool arm is in place is saved, and the tool changing speed is increased; for tools with different weight, the larger the current value or torque value of a servo drive motor is, the tool is heavier, and the smaller the current value or torque value of a servo drive motor is, the tool is lighter. In the tool changing step, the rotating speed of the servo drive motor is adjusted by detecting the current value or torque value of the servo drive motor to change a larger tool and a heavier tool at a lower speed and change a smaller tool and a lighter tool at a higher speed, so that centrifugal force during rotation of the tool can be effectively controlled, and the servo drive motor is prevented from damage under action of centrifugal force of the tool when drives the tool to rotate; and in addition, the rotating speed is set according to tools with different weight to reduce or avoid impact generated when the tool is positioned to improve the machining precision.

Description

technical field [0001] The invention relates to a tool change control method of a servo tool magazine. Background technique [0002] In the process of CNC machine tool processing, in order to improve the productivity of the machine tool, it is effective to shorten the tool change time of the tool. In order to shorten the tool change time, it is better for the machine tool to complete the movement of the tool for the next process before ending the processing of the current process. The tool change action of the existing tool magazine is one step after another. When some steps are in place, it is necessary to wait for the end of the next step before starting the next action. Therefore, the tool change efficiency is not very high. [0003] In addition, the multiple tools accommodated in the tool magazine are used for different processing. Therefore, the weight of each tool is varied. When a heavier tool is moved and changed, the kinetic energy of the moving object is greater...
