Description
Technical field
The utility model relates to machine tool field, particularly automatic withdrawal boring cutter box on a kind of heavy horizontal lathe.
Background technology
Heavy horizontal-type boring lathe in the past, design mainly for endoporus processing parts, during withdrawing, point of a knife will scratch finished surface, only have through hole add man-hour cutter can from above in advance dismounting avoid scratch workpiece, but dismantle more loaded down with trivial details, in order to adapt to market development demand, improve the treatment of surfaces of components fineness, and meet processing needs.
Summary of the invention
Automatic withdrawal boring cutter box on a kind of heavy horizontal lathe is provided for the problems referred to above the utility model, its structure is: the left end of cylinder body (4) is provided with screw (1) and locking nut (2), screw (1) withstands on the inner thrust block pad (14) of cylinder body (4), the inside of cylinder body (4) is also provided with piston rod (5), butterfly spring group (3) is provided with between piston rod (5) and thrust block pad (14), piston rod (5) is fixedly connected with knife bar (7), piston rod (5) is also fixedly connected with tapered sleeve (6) by attachment screw (11), tapered sleeve (6) top is also provided with two housing screws (10), guide pad (9) is provided with bottom cylinder body (4) right-hand member, cylinder body (4) middle and upper part is connected with oil pump (12), pressure chamber (13) is provided with between piston rod (5) and cylinder body (4).
Operation principle of the present utility model: during installation, by inner butterfly spring group (3) of the pre-locking oil cylinder of screw (1), make its pretightning force meet opposing cutting force needs, ensure tapered sleeve (6) and cutter box body (9) rigid contact, tighten locking nut (2) subsequently, ensure that pretightning force does not change; Knife bar (7) is installed in tapered sleeve (6) interior square hole, by housing screw (10) locking knife bar, during withdrawing, provides enough pressure oil by hydraulic power unit, promotes piston rod (5) and drives tapered sleeve (6) and knife bar (7) to move backward, realize automatic withdrawal.
The beneficial effects of the utility model are: the utility model structure is simple, can realize automatic withdrawal, can not scratch processing work.
