Abstract

The invention discloses an automatic tool changing motion arm for a CNC (computer numerical control) machining center. The motion arm comprises two tool changing arms and an operation control system for automatically controlling the two motion arms, wherein the rear end parts of the two tool changing arms are both arranged on a horizontal rotary table; the two tool changing arms are respectively a motion arm I and a motion arm II; the motion arm I comprises a rear arm I and a front arm I which swings up and down under the driving of a hydraulic cylinder I, and the motion arm II comprises a rear arm II and a front arm II which swings up and down under the driving of a hydraulic cylinder II; the hydraulic cylinder I and the hydraulic cylinder II are respectively connected with a hydraulic oil tank by a hydraulic pipeline I and a hydraulic pipeline II; the hydraulic pipeline I and the hydraulic pipeline II are respectively provided with a reversing valve II and an electric proportional control valve II; the front end of the front arm I is provided with a tool changing structure I for changing a tool, and the front end of the front arm II is provided with a tool changing structure II for changing the tool. The automatic tool changing motion arm is reasonable in design, simple and convenient to operate, high in intelligent degree, good in use effect, flexible in action, fast in tool changing speed and simple to control.

Description

technical field [0001] The invention relates to an operating arm, in particular to an automatic tool changing operating arm for a numerical control machining center. Background technique [0002] The CNC machining center is a CNC machine tool with a tool magazine and an automatic tool changer. The automatic tool changer is an important executive mechanism of the CNC machine tool. Holder tool changer, spindle head tool changer and automatic tool changer system with tool magazine. In the actual processing process, the automatic tool changer can help CNC machine tools save auxiliary time and meet the requirements of completing multi-process and multi-step processing in one installation. The above-mentioned automatic tool changing system with a tool magazine includes an automatic tool changing device with a manipulator and an automatic tool changing device without a manipulator, wherein the automatic tool changing device with a manipulator uses a manipulator for tool change.
