Utility model content
The deficiency that the utility model exists for prior art and defect, provide one to change cutter head and knife bar can reusable vertical compression compact form metal long cutting tool bar boring cutter.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of vertical compression compact form metal long cutting tool bar boring cutter, comprise knife bar, cutter head is installed in described knife bar front end, its end installs handle of a knife, and described knife bar front end is removably connected by bindiny mechanism and described cutter head, and the addendum cone and fixed station that are positioned at boring cutter front end are contained in described bindiny mechanism, described fixed station is positioned at addendum cone front end, and described addendum cone is set in the taper hole that is positioned at cutter head center and compresses with hold-down bolt.Cutter head front central is provided with screw, and hold-down bolt to be arranged in screw thus to be pressed on knife bar by cutter head.
In said structure, described addendum cone angle of inclination is 50 ° ~ 65 °, and addendum cone angle of inclination is the angle between addendum cone bus and horizontal plane.
In said structure, the approximate circle cylinder of described fixed station to be two relative side be plane, namely the shape of fixed station is that cylindrical relative two sides cut into plane.
In said structure, uniform many gib blocks on the anterior outer wall of described knife bar, described gib block arranges along knife bar axis.
In said structure, described knife bar center is provided with limbers, and knife bar front end is provided with the apopore that multiple and described limbers is communicated with.
In said structure, described knife bar rear end is provided with cylindrical positioning boss, and boss rear end is provided with connected unit, and the relative two sides of connected unit are plane, and this connected unit is sleeved in the connecting hole of handle of a knife center.
Further, positioning boss rear end face is provided with for the groove of mounting and adjusting cushion block and the locking screw nail for installing lock-screw, bottom portion of groove and the adjustment bolt hole for mounting and adjusting bolt be opened on positioning boss front end face.
Closer, handle of a knife outer wall be evenly equipped with multiple for install hold out against screw hold out against screw hole, described in hold out against screw hole and radially arrange centered by handle of a knife center.
The beneficial effects of the utility model are:
1, the cutter head of the utility model vertical compression compact form metal long cutting tool bar boring cutter and knife bar adopt and removably connect, precision and the roughness of processing can not only be ensured, can also cutter head service life to after change cutter head, realize knife bar to reuse, thus knife bar can reach the 2-3 in original life-span doubly, reduces production cost;
2, knife bar center of the present utility model is provided with limbers, and knife bar front end is provided with the apopore that multiple and described limbers is communicated with, and improves cooling effect, thus extends the service life of cutter head cutter, reduces production cost further.
