A servo tool holder structure and its application method

Abstract

The invention relates to the field of tool holders for numerically controlled machine tools, in particular to a servo tool holder structure and a method for using the same. The servo tool holder is provided with a casing, a rear cover assembly, a box assembly, a proximity switch assembly, and a water separator. The casing is installed at the tail of the rear cover assembly, and the reducer end of the rear cover assembly is connected to the rear end of the box assembly. The proximity switch assembly is installed in the box body of the box body assembly, and the water diversion plate is installed on the movable tooth plate of the box body assembly. The motor and reducer of the rear cover group are installed on the rear cover to provide the power source; the box assembly is positioned with a three-piece ratchet structure, and the proximity switch assembly uses a cam structure to detect the locking state of the knife holder. The present invention can solve the problems existing in the prior art, such as complex movement and cumbersome structure during the positioning and indexing of the tool holder, and the difficulty of increasing the manufacturing of the tool holder parts and the assembly of the complete machine, etc. Tool change function.

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...
