Direct drive type tool magazine device of numerical control machine tool

Abstract

The invention relates to a numerical control machine tool direct drive type tool magazine device which comprises a disc type tool magazine body and a tool changing mechanism, the tool changing mechanism is fixedly installed on the back side of the disc type tool magazine body and comprises a first drive assembly and a tool changing arm, the tool changing arm is arranged in the horizontal direction, and the first drive assembly is fixedly installed on the disc type tool magazine body. Mounting bases used for clamping tools are installed at the two ends of the tool changing arm, and the first driving assembly is used for driving the tool changing arm to move in a three-dimensional mode so that the tools in the disc type tool magazine body and the tools of a machine tool spindle can be switched. The device is simple in structure, direct in driving, gear-free, friction-free, mechanical clearance-free and transmission inertia-free, the output torque and speed stability are greatly improved, the movement weight of the whole machine tool is reduced due to the light and handy structural design of the tool magazine, the interference area with the machine tool is small, and the external structure of the whole machine tool is effectively reduced.

Description

technical field [0001] The invention relates to the field of numerical control machine tools, in particular to a direct-drive tool magazine device for numerical control machine tools. Background technique [0002] CNC machine tool is the abbreviation of numerical control machine tool, which is an automatic machine tool equipped with a program control system. The control system can logically process programs with control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the numerical control device through the information carrier. After calculation and processing, various control signals are sent by the numerical control device to control the movement of the machine tool, and the parts are automatically processed according to the shape and size required by the drawing. [0003] The traditional tool magazine completes the tool change action through the structure of the motor and the mechanical cam. All of them use tradition...

Problems solved by technology

[0006] The beneficial effect of adopting the above scheme is that the lifting driving part is driven to rotate horizontally by rotating the driving part, thereby driving the tool changing arm to rotate horizontally, so that the mounting seats at both ends of the tool changing arm and the tool of the machine tool spindle and the disc type tool magazine body are rotated out. The tool is concentric, and then the lifting driver drives the tool change arm to move upward, so that the tool on the machine tool spindle and the tool turned out of the disc-type tool magazine body are respectively located in the mounting seats at both ends of the tool change arm, and then through the control of the two ends of the tool change arm The mounting seat clamps the corresponding tool, and then the lifting driving part drives the tool changing arm to move downward to complete the tool pulling work of the tool changing arm (that is, the mounting seats at both ends of the tool changing arm respectively hold the tool on the bed spindle and the disc type The tool that is rotated out of the tool magazine body is taken out), at this time, the rotating drive part drives the lifting drive part and the tool changer arm to rotate 180° to complete the tool change of the machine tool spindle and the tool rotated out of the disc-type tool magazine body, and then the The lifting driving part drives the tool change arm to move upwards to complete the tool switching work of the tool of the machine tool spindle and the tool transferred out of the disc-type tool magazine body. Quickly, it solves the problem that the traditional disc-type tool magazine body uses a mechanical cam structure to complete the complex tool change action
