After assembly, offsets at the top of bottom and cutter hub after two blade bearing inner side planes offset, be equivalent to blade bearing bottom
Two slot structures and three slot structures at the top of cutter hub are engaged, form positioning, and the face of carving of specially two the first grooves is distinguished
It offsets with the face of carving of two open slots, the madial wall of two the first grooves and the side wall of the second groove offset, the inside of blade bearing
Lower face and the bottom surface of the second groove offset, and two fastening screws are screwed into across waist-shaped hole in the screw hole of cutter hub, two adjusting spiral shells
Silk is screwed into adjusting screw hole.
Preferably, being equipped with the upward interior cooling hole in Y-shaped among the cutter hub bottom, interior cooling hole is from cutter hub
Between position be divided into two-way, double interior cooling holes are cooling simultaneously to both sides, and the side wall in the exit of cooling hole is set as groove structure.
Preferably, being set on cutter hub lower horizontal direction there are two the mutually perpendicular through-hole of axis, one of them is logical
It is equipped in hole and reinforces bolt, for transmitting torque, improve intensity.
Preferably, the turning point in the blade installation slot is equipped with chamfering.
Preferably, cutter hub front and rear sides upper position is equipped with scale, corresponding blade bearing outside side bottom position
Scale has been installed, degree of regulation is improved.
Preferably, the bottom of second groove is equipped with boss, boss upper surface offsets with blade bearing bottom surface.
Preferably, being cased with washer in the fastening screw, locking blade bearing is more secured.
The beneficial effects of the utility model are：It assembles and easy to adjust, locking blade bearing is more secured, blade bearing and knife
Body used positioning, three face paste locking structures greatly to enhance cutter rigidity and intensity, reduce vibration cutting, improve hole and add
The quality of work is, it can be achieved that heavy cut.In addition, the double interior cooling holes of band on cutter hub, improve the processing quality of rough bore, extend knife
The service life of piece reduces the use cost of cutter.
