Specific embodiment
The present invention is described further with reference to the accompanying drawing.
As shown in Figures 1 to 4, a kind of countersink tooling that can quickly adjust positioning, including knife-containing block 1, on the knife-containing block 1
It is removably installed the cutter 2 of processing, the knife-containing block 1 is removably installed in main borehole axis (not shown),
And it is rotated together with main borehole axis.The knife-containing block 1 is designed as Breeches type, and the center of the knife-containing block 1 is provided with dress
Cutter block mounting hole 3, the knife-containing block 1 are installed on main borehole axis by knife-containing block mounting hole 3, and 1 both ends of knife-containing block are symmetrically set
Tool mounting hole 4 there are two setting, tool mounting hole 4 is rectangular herein, and cutter 2 is installed on the dress knife by tool mounting hole 4
In block 1, and the center line of the center line of symmetrical two tool mounting holes 4 and knife-containing block mounting hole 3 is in the same plane.Institute
The upper one end for stating knife-containing block mounting hole 3 offers dowel hole 5, and dowel hole 5 is arranged one herein, is fixedly installed on main borehole axis
There is key (not shown), the stretching main borehole shaft portion of key sticks into dowel hole 5, so that the knife-containing block 1 can be with main brill
Hole axle rotates together, and main borehole axis upper diameter herein is greater than lower diameter, forms a rotary table in upper and lower part junction
Rank, knife-containing block are just stuck at rotary table rank, prevent knife-containing block from moving up, and the end of rotary table rank, and edge is arranged in key herein
Main borehole axis axis direction extends a part, and the extension of key can be just stuck in completely in the dowel hole 5, so that dress knife
Block 1 can be rotated together with main borehole axis, meanwhile, knife-containing block retaining spiral shell is offered in the top another end of the knife-containing block mounting hole 3
Pit 6, knife-containing block retaining threaded hole 6 is arranged one herein, and knife-containing block retaining threaded hole 6 is connected to knife-containing block mounting hole 4, and is led to
It crosses knife-containing block Dogbolt (not shown) and holds out against main borehole axis across knife-containing block retaining threaded hole 6, realize knife-containing block 1 and master
The locking of bore hole axis, in this way setting prevent from going out in the course of work so that entire knife-containing block 1 keeps stable connection with main borehole axis
The case where existing knife-containing block 1 loosens.
Cutter fastening thread hole is set along the centerline direction of the tool mounting hole 4 respectively at 1 both ends of knife-containing block
7, two cutter fastening thread holes 7 are respectively set in both ends herein, and cutter fastening thread hole 7 is connected to tool mounting hole 4,
The cutter fastening thread hole 7 is passed through by corresponding four cutter fastening bolts 8 and holds out against the cutter 2, realizes cutter 2 and dress
The locking of cutter block 1, meanwhile, the head direction of four cutter fastening bolts 8 is identical as main borehole axis direction of rotation, and setting in this way makes
It obtains cutter 2 to be firmly fixed together with knife-containing block 1, ensure that the reliability of process.
As it can be seen in figures 5 and 6,9 edge of blade in the cutter 2 is provided with U-shaped chip curling groove 10, bits slag is passed 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
Service life.

It is 15~45 °, α is designed as 30 ° herein, and the blade and knife handle angulation of the cutter 2 are 2 α.
The type that the tool 2 can be processed according to actual needs carries out unrestricted choice, two cutters herein
One is flat scraper, and another handle is Arc scraper, considerably increases the versatility of this tooling.
On the basis of previous embodiment, in order to save to the knife time, it can be used to broach shell (not shown), broach shell set
Be calculated as circular ring shape, be to the circular ring shape design of terminations of broach shell it is identical as the structure of actually required processing, when use, can be direct
By cutter 2 by being aligned to broach shell, then cutter 2 is fixed by screwing cutter fastening bolt 8, is greatly saved to knife
Time.
When installation, first flat scraper and Arc scraper are put into respectively in tool mounting hole 4, flat scraper and circular arc are scraped
Knife is aligned by way of measurement or by then tightening four cutter fastening bolts 8 to the alignment of broach shell (not shown),
Complete the assembly of flat scraper and Arc scraper and knife-containing block 1；Then knife-containing block mounting hole 3 is directed at main borehole axis (in figure not
Show), it moves up knife-containing block 1 along main borehole axis, when moving on to the position of key, by 5 alignment keys of dowel hole, and sticks into key completely
In dowel hole 5, knife-containing block fastening bolt (not shown) is then tightened, entire countersink tooling and main borehole axis are completed at this time
Assembly.
When processing, power device (not shown) drives the rotation of main borehole axis, and main borehole axis drives key rotation, and key drives
Knife-containing block 1 rotates, and knife-containing block 1 drives flat scraper and Arc scraper to rotate simultaneously, to process to workpiece.
Novel countersink tooling of the present invention adopts a split structure design, so that cutter is detachable with knife-containing block, knife
It can directly remove and repair after tool abrasion, can remove and be replaced after tool damage, be unlikely to integral replacing as before
Equipment cost is greatly saved in tooling；When needing to process different pore size, integral replacing tooling is not had to, directly adjustment cutterhead
Switching can be realized in portion's outreach, realizes the general purpose of tooling well, and installation is easy to operate, greatly reduces
Labor intensity of workers.
The invention is not limited to specific embodiments above-mentioned.The present invention, which expands to, any in the present specification to be disclosed
New feature or any new combination, and disclose any new method or process the step of or any new combination.If this
