A kind of nut positioning combining plane cutter
Technical field
The invention belongs to woodworking machinery field, relate in particular to a kind of nut positioning combining plane cutter.
background technology
On market, planing tool used is all generally that blade is directly installed on main shaft now, and the planing tool of this structure exists following shortcoming: the one, and the poor stability of blade when planing tool runs up; The 2nd, installing/dismounting trouble for the longer planing tool of cutter hub and while changing the cutter blade damaging, wastes time and energy.
summary of the invention
The invention provides a kind of nut positioning combining plane cutter, solved the shortcoming that the planing tool poor stability in background technology, installing/dismounting bother.
Technical scheme of the present invention is achieved in that a kind of nut positioning combining plane cutter, comprise main shaft, main shaft two ends are equipped with nut B, on main shaft, interval is equipped with planing tool A and planing tool B, main shaft is provided with screw thread, between planing tool A and planing tool B, be equipped with nut A, nut A is provided with groove II, is respectively equipped with the protruding key matching with groove II on planing tool A and planing tool B;
Planing tool A is provided with screw hole II and taper hole I, and planing tool B is provided with screw hole II I and taper hole II, is equipped with pin in screw hole II, pin one end is positioned at the taper hole II of adjacent planing tool B, in screw hole II I, be equipped with pin, pin one end is positioned at the taper hole I of adjacent planing tool A, and nut B is provided with screw hole I and groove I.
The invention has the beneficial effects as follows: planing tool main shaft of the present invention is provided with screw thread, is equipped with the nut with groove between planing tool, the planing tool mounted configuration of this structure is stable, and simple, time saving and energy saving for the blade exchange damaging.
