Detailed description of the invention
Defer to technique scheme, see Fig. 1-3, loose knife-clamping device for interior cold machine tool chief axis of the present utility model, comprise main shaft, cutter and oil cylinder 13, broaching tool bar 3 is provided with in main shaft, broaching tool bar 3 one end connects cutter by claw 1, and broaching tool bar 3 is set with butterfly spring 14 and fixed cover 5 successively along its axis direction, and fixed cover 5 and broaching tool bar 3 are connected; Broaching tool bar 3 is also provided with driving member, and driving member promotes fixed cover 5 and broaching tool bar 3 moves forward along main-shaft axis direction, and fixed cover 5 compresses butterfly spring 14, realizes loose cutter action; After described loose cutter action completes, driving member departs from fixed cover 4, and under the effect of butterfly spring 14 restoring force, fixed cover 5 and broaching tool bar 3 move behind main-shaft axis direction, realizes the action of folder cutter.
Particularly, described driving member comprises the piston 7 be arranged in oil cylinder 13, is provided with rotating shaft 6 in piston 7, and rotating shaft 6 can relative to piston 7 along own axis, and the other end of described broaching tool bar 3 inserts rotating shaft 6 inside, and the two is not connected; Gap, between piston 7 and rotating shaft 6, is left between fixed cover 5 and piston 7 in one end of described fixed cover 5, rotating shaft 6 with can move along its axis direction relative to fixed cover 5; The other end of described fixed cover 5 is installed on described broaching tool bar 3 by screw thread.Described rotating shaft 6 is connected by key 11 with between fixed cover 5, and key 11 is installed on rotating shaft 6.
Described broaching tool bar 3 comprises broaching tool bar anterior 301 and broaching tool bar rear portion 302, and the two is connected by screw thread; Broaching tool bar front portion 301 is provided with claw mandrel 2, claw mandrel 2 is arranged described claw 1, and claw 1 clamps the blind rivet 10 of cutter.Described butterfly spring 14 and fixed cover 5 are sleeved on broaching tool bar rear portion 302.
Device of the present utility model, its loose cutter process is as follows: the piston 7 in oil cylinder 13 moves forward under oil pressure effect, and driven rotary axle 6 moves forward together simultaneously, and the key 11 now on rotating shaft 6 moves forward relative to fixed cover 5, and rotating shaft 6 moves forward relative to broaching tool bar 3; Piston 7 contacts fixed cover 5, and promote fixed cover 5 and move forward together with broaching tool bar 3, butterfly spring 14 is compressed, and claw mandrel 2 moves forward together with claw 1, and when arriving groove 4 place on main shaft inwall when claw 1, claw 1 opens, and unclamps blind rivet 10; In above-mentioned loose cutter process, when the left part of nut 8 contacts with oil cylinder upper cylinder cover, loose cutter action completes.
