Automatic tool changing device of simple computer numerical control machining center

Abstract

The invention provides an automatic tool changing device of a simple computer numerical control machining center and relates to the field of numerical control machine tool equipment. The automatic tool changing device comprises a base, wherein a first seat body, a second seat body and a third seat body are sequentially arranged on the base from left to right, a shaft hole is formed in the upper end of the first seat body, a rotary shaft is arranged in the shaft hole, the left end of the rotary shaft is connected with a transmission, the right end of the rotary shaft is connected with a tool disc, and various tools are installed on the tool disc. A tool bit is installed on the tool disc through a clamping-connecting device, a sliding way is formed in the second seat body, a tool seat is arranged in the sliding way, a tool handle is arranged on the tool seat, and the central height of the tool handle is equal to the lowest point of the central height of the tool bit. An air cylinder is arranged on the third seat body, and a pushing rod is arranged on the left side of the air cylinder and is in contact with the bottom of the tool seat. The automatic tool changing device further comprises a controller, wherein the controller is connected with a motor and the air cylinder, and the work of the motor and the work of the air cylinder are controlled through preset numerical values. The automatic tool changing device is simple in structure and easy to operate and enables automatic tool change to be more convenient and efficient.

Description

technical field [0001] The invention relates to the field of numerical control machine tool equipment, in particular to a simple automatic tool changer for a numerical control machining center. 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. CNC machine tools solve complex, precise, small-batch, and multi-variety parts processing problems. It is a flexible, high-efficiency automatic mac...

AI Technical Summary

Problems solved by technology

The tool holder is an important part of the CNC machine tool. The blade is fixed on the tool holder so that the blade can process the shaft material. The existing tool holder has a single structure, and the blade adopts a single fixed structure. It is difficult to replace the blade. Different parts of the shaft material When processing, it is necessary to adjust the position of the blade. The existing blade generally needs to be removed and reinstalled after changing the position. The installation process is cumbersome and the work efficiency is low. Most of the automatic tool change devices of the machining centers in the prior art are realized by buckles. The tool is connected to the rotating device, and the buckle is easy to be worn during repeated use, so that the connection between the tool and the rotating device is not firm, and the tool falls in the machining center casing, which affects the performance of the machining center
