Described cutter head is the step cutter head, and the preceding stage upper surface of cutter head front portion is the blade installed surface, and its shape is identical with blade shapes, and back stage upper surface thereafter is the blade stationary plane, and the blade stationary plane exceeds the distance of a blade thickness than blade installed surface.
Described securing member is holding screw.
It is the circular gap groove that two stage junctions of described step cutter head are provided with cross section.
Described clearance groove diameter is 0.5mm ~ 0.8mm.
Described handle of a knife and cutter hub junction are provided with the transition inclined-plane, and the angle γ between described transition inclined-plane and the horizontal plane is 45 °.
The shape of the shape of described blade fixed head and cutter head upper surface is complementary.
The major flank of described blade and the angle α between the vertical plane are 2 ° ~ 5 °.
Angle β between the front of described blade and the vertical plane and major flank equate with angle α between the vertical plane.
Described cutter hub material is the 45# steel.
The beneficial effects of the utility model are:
1, the V-arrangement boss that is provided with on V-shaped groove and the blade fixed head of the upper surface of blade of the present utility model is complementary, accurate positioning, adopt holding screw fixedly to guarantee the clamping force of blade fixed head and blade, be applicable to roughing and fine finishining, when more renewing blade, unclamp holding screw, new blade is being clamped on the cutter head, clamping aspect, quick.
2, on overall structure of the present utility model, the not energon reconditioning or tipping takes place scrap when handling of existing cutter, the utility model only need be changed a new blade just can continue use, has reduced the purchase cost of cutter, has prolonged the service life of cutter.
3, select for use in material of the present utility model, blade clamping part material of the present utility model is carbide alloy, has increased intensity, has reduced the phenomenon of breaking, has saved the time of changing to, and has improved production efficiency.
