a, installing a cutter in a cutter holder clamping jaw (14), locking the cutter holder clamping jaw (14) through a cutter holder positioning pin (8), locking the cutter holder clamping jaw (14) by the cutter holder positioning pin (8) in a normal state, enabling the cutter holder clamping jaw (14) to clamp the cutter to perform rotary motion in a vertical plane, enabling the cutter not to fall down under the action of gravity, and pushing up the cutter holder positioning pin (8) through a hydraulic cylinder (11) when the cutter is moved to a cutter changing point, wherein the clamping force of the cutter holder clamping jaw (14) can ensure the fixing of the cutter in a horizontal position;
b: the hydraulic oil cylinder (11) is an execution unit controlled by a hydraulic system, and the oil cylinder bracket (3) is driven to move back and forth by the expansion and contraction of an output shaft of the hydraulic oil cylinder (11) so as to realize the pressing of the tool holder locating pin (8);
c: the oil cylinder bracket (3) is of an L-shaped structure, the upper side and the lower side of the oil cylinder bracket are symmetrically connected with the two hydraulic oil cylinders (11), the front and the rear motions can be realized along with the extension of the output shafts of the hydraulic oil cylinders (11), the vertical surface at the front ends of the output shafts of the extended hydraulic oil cylinders (11) can be contacted with the tool holder positioning pins (8) and can jack the tool holder positioning pins (8) forwards, and at the moment, the tool holder clamping jaw (14) is opened in a safe manner;
d: the tool is clamped by the front-end tool holder clamping jaw (14), the tool changing action is divided into two actions of tool taking and tool returning, when the tool taking action is performed, the spindle (1) is in butt joint with the tool holder taper hole (9) and then locks the tool, the tool can be pulled out from the opening direction of the tool holder clamping jaw (14) for opening safety through a machine tool driving shaft, when the tool is returned, the tool holder clamping jaw (14) can be jacked through the driving shaft in the opening direction of the tool holder clamping jaw (14), after the tool holder clamping jaw (14) is closed and clamped, the spindle (1) loosens the tool and withdraws from a tool changing point from the rear side, and the whole tool changing action is completed.
