Rotating tower type tool magazine knife-selecting device of numerically controlled machine

Abstract

The invention belongs to the technical field of numerical control machine tool and in particular relates to a cutter selection device of a rotary tower cutter warehouse of a numerical control machine tool. A cutter motor is arranged on a base; the cutter motor drives a sliding shaft sleeve and a cutter shaft to rotate through a transmission belt and a driven wheel; the sliding shaft sleeve is connected with a cutter shaft through a second clutch disc; a piston rod of a small cylinder is connected with the sliding shaft sleeve and drives the sliding shaft sleeve to slide in the driven wheel so as to realize on-off between the sliding shaft sleeve and the cutter shaft through the second clutch disc; the sliding shaft sleeve can realize sliding and synchronous rotation in the driven wheel through sliding teeth; the outer end part of a camshaft of a large cylinder which is arranged on the base and is connected with a cylinder piston is fixedly connected with a cutter disc and can drive the on-off between the cutter disc and the base; a motor of the cutter disc drives the camshaft and the cutter disc to rotate through a separation mechanism of the cutter disc; and the action of the motor, the large cylinder and the small cylinder is controlled through a controller. The cutter selection device has the advantages that the cutter selection device has a simple structure, low cost, low working noise, convenient mounting and maintenance and is suitable to be popularized and applied to various numerical control machine tools.

Description

technical field [0001] The invention belongs to the technical field of numerical control machine tools, in particular to a tool selection device for a turret type tool magazine of a numerical control machine tool. Background technique [0002] At present, the turret-type tool selection devices of CNC machine tools at home and abroad all use transmission mechanisms such as tool disc separation mechanisms, connecting rod mechanisms, and conveyor belts to transmit power and realize some special actions. The disadvantages are: the above-mentioned transmission The structure of the mechanism is complex, the working noise is large, the parts have many failures, the wear is serious, the installation and maintenance are difficult, the installation and maintenance take a long time, the production efficiency is low, the production cost is high, and the service life is short. Contents of the invention [0003] The object of the present invention is to provide a turret-type tool magazi...
