Claims

[Scope of Claim for Utility Model Registration] An automatic tool changer that automatically exchanges tools between a magazine with a large number of tool pots in which tools are stored and the main shaft of a machine tool, and a chuck that grips the tools. a tool exchange arm provided at two locations, an arm drive shaft for driving this arm, a hollow arm support member set to intersect with the arm drive shaft and supporting the drive shaft, and the arm drive shaft and A cylinder part for advancing and retracting the arm that is arranged in parallel and connects and drives the arm drive shaft via a link lever, and a pinion that is inserted into the arm support member and fitted into the rotation shaft in the arm drive shaft. The link lever is equipped with a cylinder part for arm rotation with a rack carved into the cylinder rod, and a drive mechanism such as a cam and a link for converting the rotation of the motor into the movement of the cylinder part for advancing and retracting the arm and the cylinder part for arm rotation. An automatic tool changer characterized in that a lever support member that supports the lever support member and an arm support member are fixed to a slider that is arranged to be movable up and down with respect to a drive mechanism main body that incorporates a cam and a link mechanism.
