Automatic tool changer of circular cutter holders for CNC machining center

Abstract

The invention discloses an automatic tool changer of circular cutter holders for a CNC machining center. The automatic tool changer comprises an automatic tool changing control system, an electric lifting support, an electric lifting driving mechanism, a vertically rotary stand rod, a rotation driving mechanism, the rough machining circular cutter holder and the finish machining circular cutter holder, wherein the rough machining circular cutter holder and the finish machining circular cutter holder are installed on the vertically rotary stand rod. The automatic tool changing control system is connected with a numerical control system of the CNC machining center. The finish machining circular cutter holder is located under the rough machining circular cutter holder. The automatic tool changing control system comprises a data processor, a first turning angle storage unit, a second turning angle storage unit, a first tool model input unit, a second tool model input unit, a tool installation height detection unit, a first tool rest height detection unit and a second tool rest height detection unit. The automatic tool changer is reasonable in design, easy and convenient to operate, high in intelligent degree, good in using effect and capable of changing tools automatically according to rough and finish machining procedures on workpieces by the CNC machining center and meeting the requirement for automatic tool changing of many tools.

Description

technical field [0001] The invention relates to an automatic tool changing device, in particular to an automatic tool changing device for a rotary tool rest used in 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 rotary tool holder is a relatively simple automatic tool change device. The commonly used rotary tool holders mainly include square tool holders and hexagonal tool holders, that is, four or six knives are installed on the tool holders. However, in the a...
