Problems solved by technology

[0003] When changing tools, store various tools together on the tool holder, and use the tools on the tool holder to grind the workpiece on the CNC machine tool. During the grinding process of the workpiece, the tool holder will be damaged due to grinding The force generates a certain vibration force, so that the tool installed on the tool holder will loosen due to the grinding vibration force, causing the tool to be easily misplaced or accidentally detached from the tool holder, causing damage to the tool and affecting the overall operation of the machine tool State, also reduce the service life of the machine tool, reduce the grinding efficiency of the workpiece

Abstract

The invention discloses an automatic tool changing device for a numerically controlled machine tool, the structure of which includes a main body, a motor, a guide rail, a tool changing arm, a wheel disc, a tool holder, and an anti-tripping device. When the invention is improved and used, the tool can be stably installed On the clamping seat, the extruding arm will be pushed by the tool, and the two friction pads will resist the friction with the contact surface of the tool. The tool can be stably clamped on the two extruding arms, so that the tool can be stably fixed inside the connecting cavity. The tool will push the movable sleeve downward during the grinding vibration process, and the vibration feeling generated by the grinding workpiece will be eliminated by the spring pressing piece. Elimination, it is supported by the triangular plate, so that the resisting part and the pressing part are opposed to each other, preventing the retracting deformation of the triangular plate, ensuring the stability of the tool grinding and the grinding efficiency of the workpiece.

Description

technical field [0001] The invention relates to the field of numerically controlled machine tools, in particular to an automatic tool changing device for numerically controlled machine tools. Background technique [0002] CNC machine tool is an automatic machine tool equipped with a program control system. With the control of computer programs, it can complete various processing requirements, such as milling, drilling, boring, tapping, etc., and automatically process parts. The library system is to provide the tool storage and tool change requirements required in the automatic machining process of CNC machine tools, and greatly shorten the processing time. When using the tool change, the areas that need to be improved: [0003] When changing tools, store various tools together on the tool holder, and use the tools on the tool holder to grind the workpiece on the CNC machine tool. During the grinding process of the workpiece, the tool holder will be damaged due to grinding ...
