Abstract

The invention relates to an air-tight seal structure for a driven tool holder. The air-tight seal structure involves a tool holder box body and a flange plate fixedly arranged on the tool holder box body; box body communication holes are distributed in the tool holder box body; flange communication holes communicating with the box body communication holes are distributed in the flange plate; and second sealing rings are arranged between the box body communication holes and the flange communication holes. The air-tight seal structure is simple in structure, compressed air is introduced into anair inlet hole of the box body during working and enters a sealing labyrinth along the box body communication holes and the flange communication holes, an air-tight seal system with certain stable pressure is formed, and the effect of preventing cutting fluid and impurities from entering the box body is achieved.

Description

technical field [0001] The invention belongs to the technical field of a power tool seat, and in particular relates to an air-tight structure for a power tool seat. Background technique [0002] The front end of the driven tool holder is equipped with tools, and the rear end is installed on the driven turret. It is mainly used on CNC lathes, and the driven tool holder drives the tool for cutting. Therefore, the sealing performance of the tool holder is very important to product quality. The sealing form of the power tool holder currently used is mainly based on the rotating seal ring and the labyrinth structure. The seal ring acts as the main seal to prevent cutting fluid and other fluids from entering the tool holder box, and the labyrinth acts as an auxiliary seal. Large other impurities enter. At present, the defects of the traditional sealing form are as follows: because the cutting fluid will enter the sealing area of ​​the sealing ring and the shaft, the grease on the...
