Background technology
Machining manufacturing industry is a national basic activity, also determines a manufacturing integral level of country,
Its development level directly influences the raising of each department of national economy technical merit and economic benefit.And be machined manufacture from
The use of tool is not operated on.At present, one of most popular shape of tool is circular, such as lathe tool, milling cutter etc..This is due to circle
Shape is a kind of general, flexible shape, and circular knives can be with multiple rotary so as to cost-effective.
When circular knife carries out machining, cylindrical usually using circular knife is used as cutting edge to be cut.Due to cutting
Depth and circular knife diameter it is different, therefore circular knife participate in every time cutting cutting edge girth it is different, thus rotation can be passed through
Turn certain angle and circular knife is used for multiple times.
But be not provided with marking on existing circular knife, when operating personnel need to change the cutting edge worn,
Generally with feeling to rotate a certain angle, if rotating through more, the usable number of blade can be reduced, causes to waste；If
Rotate very few, participate in cutting again using the cutting edge worn, it is possible to workpiece size deviation is caused, so as to cause workpiece report
It is useless.
In addition, when conventional circular knife is installed with cutter hub, compressed usually using screw lock or pressing plate, or screw lock
The mode compressed with pressing plate uses simultaneously.Although conventional locking mode can to circular knife up and down, left and right formed effectively limit
System, but the circle rotation direction of circular knife can not be completely fixed, once cutting force is larger, it is very easy to cause dise knife
Piece rotates in circumferencial direction, so as to damage cutter and workpiece.

The alignment pin fixture 10 (such as lock-screw) of pin 7, it is ensured that when blade 1 works, alignment pin 7 is always positioned in indexing trough 2, is prevented
Only blade 1 rotates in a circumferential direction.
The top of the block 80 of the through hole 8 is provided with the first internal thread 81, and the alignment pin fixture 10 is provided with least
Two the first external screw threads 101 of circle, first internal thread 81 match with the first external screw thread 101.When the alignment pin fixture 10
When coordinating with the screw thread of through hole 8, the locking positioning pin 7 of alignment pin fixture 10, to prevent alignment pin 7 under external force
Moved up in through hole 8；When the first internal thread of the first external screw thread 101 and the through hole 8 of the alignment pin fixture 10
During 81 separation (when alignment pin and alignment pin fixture are not in lock-out state), the alignment pin 7 is in the presence of external force
Certain distance can be moved up in through hole 8, it is ensured that the lower section of alignment pin 7 is completely into through hole 8, so that it is guaranteed that blade 1 can
To rotate under external force.
The lower section of the alignment pin fixture 10 is preferably provided with a groove, and the upper end of the alignment pin 7 can be inserted into institute
State in groove, it can be ensured that locking mechanism is stable and firm；Or the top of the alignment pin 7 is provided with a groove, the alignment pin
The lower section of fixture 10 can be inserted into the groove.
Second of alignment pin and through hole fit system of the present embodiment, as shown in Figures 3 and 4, the cutter hub 3 are provided with one and used
In the through hole 8 for plugging alignment pin 7, the lower section of the alignment pin 7 through the through hole 8 and is plugged in the indexing trough 2 of the blade 1
It is interior.
As shown in fig. 7, being provided with the second internal thread 82 in the through hole 8, the alignment pin 7 is provided with the second external screw thread 72,
Second internal thread 82 matches with the second external screw thread 72, and the top of the alignment pin 7 passes through hole 8, be easy to clockwise or
Alignment pin 7 is rotated counterclockwise, consequently facilitating moving up or down alignment pin 7.When by rotating clockwise alignment pin 7, institute
The indexing trough 2 that alignment pin 7 holds out against blade 1 is stated, to lock blade 1；Or by rotating counterclockwise alignment pin 7, make alignment pin 7
Depart from indexing trough 2, with rotating blade 1.
First, the installation process of the blade of the present embodiment is as follows：
(1) the receiving space position of cutter hub 3 and cutter hub is first cleaned；Then, installation alignment pin is checked, and is consolidated by alignment pin
Determine the locking positioning pin 7 of part 10；
(2) back side of blade 1 is adjacent to blade back side locating surface 4, side is adjacent to blade side locating surface 5, will wherein one
Indexing trough 2 is adjacent to alignment pin 7；The centre bore 11 of blade 1 is passed through using blade fixture 6, and is connected and locks with knife mounting hole 41
Tightly, you can use.
2nd, the diameter of the circular knife of the present embodiment can be 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, 16mm,
20mm、25mm、32mm.The cutting depth and number of revolutions relation table of 10mm and 12mm circular knife are exemplified below, such as the institute of table 1
Show.
The cutting depth of table 1 and number of revolutions relation table
3rd, the fine rotational process of the blade of the present embodiment is as follows：
By taking the first alignment pin of the present embodiment and through hole fit system as an example.
(1) number of revolutions is first confirmed.
For example, as shown in figure 8, when each cutting depth (height distance of face to be processed and machined surface) is 0.3mm,
The angle that the blade of a diameter of 10mm (radius R=5mm) participates in cutting tip is about 20 degree, and due to circular knife, one week is 360 degree,
Therefore 18 times (360/20=18) about can be used.Therefore according to cutting depth and number of revolutions relation table (table 1), and blade indexing trough
Actual quantity, selection use 16 times, i.e., turn an indexing trough every time.
And for example, as shown in figure 9, when each cutting depth is in 1mm, it is about 37 degree that it, which participates in cutting tip angle, and 360/
37 are approximately equal to 9 times, and according to cutting depth and number of revolutions relation table, selection uses 8 times.Turn 2 indexing troughs every time.
(2) cleaning blade and cutter hub；Alignment pin fixture 10 to alignment pin 7 is unclamped to move in through hole.
(3) blade fixture 6 to blade 1 is unclamped freely to rotate around blade fixture 6；
(4) blade 1 is rotated counterclockwise, moved up due to the stress pressuring spring 9 of alignment pin 7 and into through hole, when
Blade 1 rotates through an indexing trough 2, into the room of next indexing trough 2, because the elastic force of spring 9 is by the bottom bullet of alignment pin 7
Go out through hole 8 (sensation by sound or on hand, learn and have turned through an indexing trough 2), stop operating blade 1；
(5) alignment pin fixture 10 is locked；
(6) blade fixture 6 is locked；It can be used.
4th, the process of the blade more renewed
(1) it is totally released and removes blade fixture 6；
(2) blade 1 is removed；
(3) the receiving space position of cutter hub 3 and cutter hub is first cleaned；Then, installation alignment pin is checked, and is consolidated by alignment pin
Determine the locking positioning pin 7 of part 10；
(4) back side of blade 1 is adjacent to blade back side locating surface 4, side is adjacent to blade side locating surface 5, will wherein one
Indexing trough 2 is adjacent to alignment pin 7；The centre bore 11 of blade 1 is passed through using blade fixture 6, and is connected and locks with knife mounting hole 41
Tightly, you can use.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made.These improve and
Retouching also should be regarded as the scope of protection of the utility model.
