Mounting hole is equipped in the middle part of the ontology, mounting hole medial surface is equipped with the second keyway of perforation；The outer body
Blade mounting portion there are three being set on face；The lateral surface of three blade mounting portions is arc, the internal diameter with counterbore to be processed
It matches；Three blade mounting portions are respectively the first blade mounting portion, the second blade mounting portion and third blade mounting portion；
Three blades are respectively the first blade, the second blade and third blade；
First blade is removably arranged on the first blade mounting portion, medial surface and the medial surface in hole to be processed
It matches；Second blade is removably arranged on the second blade mounting portion, the lateral surface of medial surface and the first blade
Flush or staggered radially, the medial surface of lateral surface and third blade flush or staggered radially；Described
Three blades are removably arranged on third blade mounting portion, the medial surface kissing of the lateral surface of third blade and counterbore to be processed
It closes；
The cutter hub is connect by key with knife bar；Stop is removably arranged on the backstop mounting portion of knife bar, for hindering
Only cutter hub comes off from knife bar.
Specifically：The hollow portion to match with backstop mounting portion is equipped in the middle part of the backstop, stop side leads to equipped with screw thread
Hole；Stop is fixedly connected with the backstop mounting portion of knife bar by screw across tapped through hole.
Application method：In use, first connecting the main shaft of the knife bar of the utility model and numerically-controlled machine tool, and make knife bar vertical
Across the hole to be processed of workpiece to be added, by cutter hub by being keyed knife bar, and make blade upward.Stop is mounted on knife bar again
On backstop mounting portion, cutter hub is prevented to come off from knife bar.Start numerically-controlled machine tool, and make machine tool chief axis axial feed, complete counterbore
Processing.Due to flush or the staggered arrangement successively radially of three blades so that three blade uniform forces, reduction are cut
Knife phenomenon of shaking during cutting, ensure that the processing quality of spot-facing.It is to be processed to after defined depth, move backward lathe master
Axis lays down backstop, gets on lower knife body from knife bar, and knife bar is exited completely, completes the processing of a counterbore.
Blade medial surface described herein refers both to blade radially close to the side in hole to be processed.
These technical solutions can also be combined with each other including improved technical solution and further improved technical solution
Or combine, so as to reach superior technique effect.
By using above-mentioned technical proposal, the utility model has following advantageous effect：
Blade can be changed quickly in a kind of major diameter counter bore backsinking cutter of the utility model, anti-suitable for major diameter counterbore
To processing, due to flush or the staggered arrangement successively radially of three blades on the cutter hub so that three blade stress
Uniformly, the knife phenomenon of shaking in working angles is reduced, the processing quality of spot-facing is ensure that, has broad application prospects.
