Servo tool rest structure and application method thereof

Abstract

The invention relates to the field of tool rests for numerical control machine tools, in particular to a servo tool rest structure and an application method thereof. The servo tool rest is provided with a shell, a rear cover plate assembly, a box assembly, a proximity switch assembly and a water division disk, wherein the shell is installed at the tail of the rear cover plate assembly, the speed reducer end of the rear cover plate assembly is connected with the rear end of the box assembly, the proximity switch assembly is installed in the box of the box assembly, and the water division disk is installed on a moving gear disk of the box assembly. A motor and a speed reducer of the rear cover plate assembly are installed on a rear cover plate and are used as a power source; the box assembly is positioned with a three-mouse-tooth disk structure, and a cam structure is adopted in the proximity switch to detect the locking state of a tool rest. With the servo tool rest structure and the application method thereof, the problems that in the prior art, motion actions are complex and the structure is complex when a tool rest is positioned and translocated, and the difficulty degree of tool rest part manufacturing and complete machine assembly are increased are solved, and the servo tool rest structure and the application method thereof are applied to numerical control machine tools and numerical control turning centers to realize tool replacement.

Description

technical field [0001] The invention relates to the field of tool holders for numerically controlled machine tools, in particular to a servo tool holder structure and a use method thereof. Background technique [0002] The tool holder is an important functional part of the CNC machine tool. The tool holder structure disclosed in US Patent No. 4,972,744 and US20050247172A1 uses a motor and a multi-stage gear to drive the cutter head to rotate. The tool holder manufacturer needs to organize the production of multi-stage gears. The box of the tool holder It is necessary to design the support mechanism of multi-stage gears and ensure the dimensional accuracy and position accuracy between the gears at all levels. The use of multi-stage gears increases the complexity of the design, and at the same time increases the difficulty of manufacturing tool holder parts and complete machine assembly. [0003] The tool holder structure disclosed in European patent EP0642884A1 needs to use a...
