Abstract
A cutter-changing device includes a cutter-magazine carrying cutters, a rotary telescopic cylinder, and a clamping sub-assembly. The clamping sub-assembly includes a cutter-changing arm, and a pair of clamping assemblies. The rotary telescopic cylinder drives the cutter-changing arm to rotate, extend and retract. Each clamping assembly includes a mounting member, an elastic member, a piston, and at least one resisting member. The mounting member is mounted on the cutter-changing arm, and defines at least one mounting hole through the sidewall thereof. The elastic member and the piston are sleeved with the mounting member, and the two opposite ends of the elastic member press against the piston and the mounting member. The resisting member is mounted between the elastic member and the mounting member, and capable of being resisted by the piston to be partially exposed from the mounting hole.
