Specific embodiment
Below in conjunction with the accompanying drawings the present invention is described further.
As shown in Figures 1 to 4, a kind of new countersink frock, including knife-containing block 1, removably installs on the knife-containing block 1
There is the cutter 2 of processing, the knife-containing block 1 is removably installed in main borehole axle（Not shown in figure）On, and with main borehole axle
Rotate together.The knife-containing block 1 is designed as Breeches type, and the center of the knife-containing block 1 is provided with knife-containing block installing hole 3,
The knife-containing block 1 is installed on main borehole axle by knife-containing block installing hole 3, and 1 two ends of the knife-containing block are symmetrically arranged with two cutters
Installing hole 4, Cutting tool installation manner hole 4 is square herein, and cutter 2 is installed in the knife-containing block 1, and symmetrically by Cutting tool installation manner hole 4
Two Cutting tool installation manner holes 4 centrage and knife-containing block installing hole 3 centrage in the same plane.Install in the knife-containing block
The upper one end in hole 3 offers dowel hole 5, and dowel hole 5 arranges one herein, is fixedly installed key on main borehole axle（In figure not
Illustrate）, the main borehole shaft portion that stretches out of key sticks into dowel hole 5, so that the knife-containing block 1 can turn with main borehole axle
Dynamic, main borehole axle upper diameter herein is more than lower diameter, defines a round platform rank, knife-containing block in upper and lower part junction
Just it is stuck at round platform rank, prevents knife-containing block from moving up, key herein is arranged on the end of round platform rank, and along main borehole axle axle
A part is extended in line direction, and the extension of key just can be stuck in the dowel hole 5 completely so that knife-containing block 1 can be with master
Bore hole axis are rotated together, meanwhile, knife-containing block retaining screwed hole 6 is offered in the top another end of the knife-containing block installing hole 3, herein
Knife-containing block retaining screwed hole 6 arranges one, and knife-containing block retaining screwed hole 6 is connected with knife-containing block installing hole 4, and is stopped by knife-containing block
Move back bolt（Not shown in figure）Main borehole axle is held out against through knife-containing block retaining screwed hole 6, the lock of knife-containing block 1 and main borehole axle is realized
Tightly, so arranging causes whole knife-containing block 1 to keep stable connection with main borehole axle, occurs knife-containing block 1 in preventing the course of work
The situation of loosening.
Cutter fastening thread hole is set along the centerline direction in the Cutting tool installation manner hole 4 respectively at 1 two ends of the knife-containing block
7, herein two ends be respectively provided with two cutter fastening thread holes 7, cutter fastening thread hole 7 is connected with Cutting tool installation manner hole 4,
The cutter 2 is held out against through the cutter fastening thread hole 7 by corresponding four cutter fastening bolts 8, realizes cutter 2 with dress
The locking of cutter block 1, meanwhile, the head direction of four cutter fastening bolts 8 is identical with main borehole axle direction of rotation, and so arranging makes
Obtain cutter 2 to be firmly fixed together with knife-containing block 1, it is ensured that the reliability of the course of processing.
As it can be seen in figures 5 and 6, being provided with U-shaped chip curling groove 10 at 9 edge of blade of the cutter 2 so that bits slag can pass through
U-shaped chip curling groove 10 is smoothly discharged out, and reduces chip removal resistance, improves the use environment of blade 9, extends the use of cutter 2
Life-span.
The angle that two 4 centrages of Cutting tool installation manner hole are formed with 3 centrage of knife-containing block installing hole is α, and α
For 15 ~ 45 °, α is designed as 30 ° herein, and blade and the handle of a knife angulation of the cutter 2 are 2 α.
