Abstract
A tool pivoting mechanism of a tool magazine for a machining center uses a pressure cylinder as an actuating means to drive a cam mechanism. The cam mechanism composes of a cam set means which moves a roller on a tool pivoting block up or down along a guiding raft, thus drives a tool pot and a cutting tool to rotate. Through the curvature change of the cam curve, the pivoting mechanism controls the displacement, velocity and acceleration of tool pivoting block, thus prevents the impact force of tool pivoting and avoids the falling off of cutting tool.
