The invention discloses a full-automatic tool changing frame which comprises a tool frame base, a tool frame support, a tool frame rod, a tool locking ball and a tool
locking mechanism. On the basis of an existing
machining tool, automatic tool changing is achieved, the structure is simple and compact, tool changing is rapid, rigidity is good, and
machining preset precision is high. When a tool is detached, installed and clamped, rapid changing for the tool can be achieved only by rotating a locking
cam, the tool is well locked, and only a few of seconds are needed for each time of tool changing. Due to the fact that the tool frame base is not moved, only a tool changing mechanical hand is needed for replacing the tool when
machining working procedures are changed, a tool
handle is locked by the locking ball, the locking effect is good, the self-centering adjusting and positioning effect can be achieved, the tool positioning precision is high, a tool disk, the tool changing mechanical hand and the locking
cam are all automatically controlled by a controller, the tool changing frame for full-automatic tool changing is achieved and can be easily applied to an existing lathe so as to improve the lathe conveniently, and the efficiency is improved.
