Abstract

The invention belongs to the field of numerical control machine tools, particularly provides a quick tool replacement method for a numerical control machine tool and a tool magazine, and aims to solve the problem of excessively long tool replacement time between a tool magazine and an electro-spindle of a conventional numerical control machine tool. The quick tool replacement method comprises the following steps: a numerical control system gives a tool replacement command; a tool chamber servomotor drives a tool chamber to rotate and to rotate a target tool to a tool replacement position; a manipulator servomotor drives a manipulator to quickly rotate to the position of a to-be-replaced tool; a tool striking cylinder starts to strike tools while the manipulator rotates, and the tool striking cylinder just finishes the tool striking action when the manipulator holds a tool on an electro-spindle; and the manipulator conducts tool replacement. Furthermore, encoders are used for accurately positioning all the tools on the tool chamber and the manipulator. The quick tool replacement method for the numerical control machine tool can not only prevent the tools from falling and being disordered, but also improve the tool replacement speed.

Description

technical field [0001] The invention belongs to the field of numerical control machine tools, and specifically provides a method for quickly replacing a tool of a numerical control machine tool and a tool magazine. Background technique [0002] At present, the tool magazine is installed with a reducer through an asynchronous motor, and then drives the cam structure to change the tool. The tool change process between the tool magazine and the electric spindle is determined by multiple proximity switches and information feedback. Due to the positioning accuracy of the proximity switch The speed of the asynchronous motor is not high, and the speed of the asynchronous motor is uncontrollable, which makes the tool change time longer. In addition, since the hydraulic tooling cylinder provides hydraulic oil and pressure through the hydraulic pump, the hydraulic loading process takes a certain amount of time, thereby increasing the tool changing time. [0003] Correspondingly, ther...
