A kind of nut location combined plane cutter
Technical field
The invention belongs to the woodworking machinery field, relate in particular to a kind of nut location combined plane cutter.
Background technology
Used planing tool generally all is that blade is directly installed on the main shaft on the market now, and there is following shortcoming in the planing tool of this structure: the one, and the poor stability of blade when planing tool runs up; The 2nd, installing/dismounting trouble for the long planing tool of cutter hub and when changing the cutter blade that damages wastes time and energy.
Summary of the invention
The invention provides a kind of nut location combined plane cutter, solved the shortcoming that the planing tool poor stability in the background technology, installing/dismounting bother.
Technical scheme of the present invention is achieved in that a kind of nut location combined plane cutter, comprises main shaft, and the main shaft two ends are equipped with nut B, be equipped with planing tool A and planing tool B on the main shaft at interval, main shaft is provided with screw thread, is equipped with nut A between planing tool A and the planing tool B, and nut A is provided with the groove II;
Screw thread on the described main shaft is the corresponding positive and negative direction screw threads in both sides;
Be respectively equipped with the protruding key that matches with the groove II on planing tool A and the planing tool B;
Planing tool A is provided with screw II and taper hole I, and planing tool B is provided with screw III and taper hole II;
Be equipped with pin in the screw II, pin one end is positioned at the taper hole II of adjacent planing tool B, is equipped with pin in the screw III, and pin one end is positioned at the taper hole I of adjacent planing tool A;
Nut B is provided with screw 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 of band groove between the planing tool, and the planing tool mounted configuration of this structure is stable, and simple, time saving and energy saving for the blade exchange that damages.
