Constant-pressure high-pressure central water outlet structure for automatic on-line CNC lathe turret tool holder

Abstract

The invention provides a constant pressure type high pressure center water drainage structure for an automatic on-line numerically controlled lathe turret. Two fluid loops are formed on a fixed shaft inside the numerically controlled lathe turret. Pressure oil is introduced into the first loop and enters a fluid separation shaft from the fixed shaft to form a pressure oil cavity to push a water drainage shaft to move forwards so as to be in sealing fit with a rotary flange; and high-pressure cooling fluid is introduced into the second loop, enters the fluid separation shaft from the fixed shaft and then enters the water drainage shaft through the fluid separation shaft, at the moment, the water drainage shaft is pushed by the pressure oil in the first loop to be in sealing fit with the rotary flange, so that cutting fluid enters the rotary flange through the water drainage shaft and enters a cutterhead through the rotary flange, and finally the high-pressure cooling fluid flows out through a water outlet in the cutterhead. By means of the constant pressure type high pressure center water drainage structure for the automatic on-line numerically controlled lathe turret, the high-pressure cooling problems of a tool and parts in the numerically controlled lathe turning process can be easily and effectively solved, and the internal space of the turret is sufficiently utilized.

Description

technical field [0001] The invention relates to the field of numerically controlled lathes, in particular to a constant-pressure high-pressure central water outlet structure for a turret tool holder of an automatic on-line numerically controlled lathe. Background technique [0002] As we all know, CNC lathes are rotary cutting machine tools, which will generate a lot of cutting heat during the turning process. At the same time, cutting will produce banded chips and chip winding, which will cause downtime, waste time, and seriously endanger the operator, damage the workpiece, and is not conducive to the machine tool. Automatic connection. After adopting the high-pressure cooling processing method, in addition to effectively reducing the cutting heat, ensuring the cutting accuracy of the machine tool, the life of the blade and the smoothness of the processed parts, it also increases the brittleness of the chips and is easy to break, and obtains short chips, so that the chips a...
