Problems solved by technology

[0003] Existing CNC machine tools need to change the tool in the tool magazine during the machining process, but the tool is constantly switching tool pockets during the tool change process, so the tool sequence will be chaotic during use, and the wrong tool will be fed differently. If the weight is light, the workpiece will be damaged due to tool collision, and if it is heavy, it will cause irreversible damage to the CNC machine tool. Therefore, an intelligent tool changer is needed

Abstract

The invention provides an intelligent numerical control machine tool tool changing frame and relates to the field of intelligent numerical control machine tools. The tool changing frame of the intelligent numerical control machine tool comprises a tool magazine box, a tool changing mechanism is fixedly installed on the inner top wall of the front end of the tool magazine box, a driving mechanism is arranged in the tool magazine box, a tool bag is fixedly installed on the outer surface of the driving mechanism, and a tool handle is connected to the middle of the tool bag in a clamped mode. According to the tool changing frame of the intelligent numerical control machine tool, a specified tool bag can be moved to a tool taking position through chain movement, an electromagnetic attraction block can be started to attract a fixed attraction block, then a limiting semi-ring can move outwards to drive a tool handle to move, and at the moment, a driving contact is in contact with a driven contact; the active contact is switched to be a path of the preset cutter handle through the controller, when the active contact and the passive contact form a complete path, namely cutter matching, the controller drives the motor and the fixed magnetic plate to attract the movable magnetic plate to complete the cutter taking action through the movement of the limiting semi-ring, and when the contacts are not matched, an alarm is given, and the problem of cutter disorder in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of intelligent numerical control machine tools, in particular to a tool changer for intelligent 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. [0003] Existing CNC machine tools need to change the tool in the tool magazine during the machining process, but the tool is constantly switching tool pockets during the tool change process, so the tool sequence will be chaotic during use, and the wrong tool will be fed differently. If the amount is light, the workpiece will be damaged by collision of the tool, and if it is heavy, i...
