自动回转刀架CNC lathe work order to be able to complete a fixture in many processes processing aids to reduce time， reduce installation time and again caused by processing errors， we must turn with automatic tool. Installed in accordance with the number of different knives， automatic revolving turret at position four of six and eight-station work spaces and other forms. According to the different installation methods， automatic rotary tool can be divided into two types of vertical and horizontal. Positioning means according to the different mechanical， automatic rotary tool set can be divided into client positioning tooth and three teeth， such as disk-based positioning. The interruption of tooth plate-type tool change position to be lifted when the tool carrier， tool change a slow and poor sealing， but its relatively simple structure. Tridentate known disk-based location-free lift-type， characterized by ATC when the tool is not lifted， so when the tool change is fast and good seal， but its more complicate
structure.
Automatic rotary tool in the structure must have good strength and rigidity to bear the rough at the time of cutting resistance. In order to ensure a high transposition of the repeat positioning accuracy， automatic rotary tool holder of the position would also like to choose a reliable and reasonable positioning program structure. Rotary Tool Automatic Tool Changer automatically by the control system and the drive circuit to achieve.
Keywords: automatic rotary tool， vice worm， Electromechanical system
