It repays part 6 and is moved to predetermined position, then lantern ring 4 is located on knife handle 2 using fixing piece, prevent lantern ring 4 from occurring with respect to knife handle 2
Secondary movement and cause compensating part 6 to change with respect to the position of cutterhead 1.In the present embodiment, multiple frictions are provided on lantern ring 4
The outer surface of rib (unlabeled in figure), friction rib from lantern ring 4 projects, and multiple friction ribs are set parallel to each other, multiple frictions
Rib surrounds the central axis circular array of lantern ring 4, and in actual use, user pinches lantern ring 4 with finger, so that finger contradicts
On friction rib, it is convenient for user easily rotational lantern ring 4.
There are two fixation holes 13, two fixation holes 13 to be collinearly arranged for setting on the lantern ring 4, the central axis of accommodating hole 7
Line between two fixation holes 13 is vertically arranged；The quantity of fixing piece is two, and two fixing pieces are located in two respectively
In fixation hole 13, fixing piece includes that activity is installed in the friction member 14 in fixation hole 13, the threaded post that is screwed onto fixation hole 13
15, threaded post 15 pushes away friction member 14 so that friction member 14 is contradicted in the outer surface of knife handle 2 for squeezing.When lantern ring 4 is with respect to knife
After handle 2 turns to predetermined position, user rotates threaded post 15 using extraneous screwdriver, and threaded post 15 can be in fixation hole 13
It is interior mobile relative to lantern ring 4, it can be squeezed when threaded post 15 moves in fixation hole 13 and push away the conflict of friction member 14 in the outer surface of knife handle 2
On, lantern ring 4 is located in the predetermined position on knife handle 2 using the frictional force between friction member 14 and knife handle 2.Utilize two fixations
Friction member 14 is contradicted respectively on the two sides of knife handle 2 in hole 13, so that the two sides stress equalization of knife handle 2, it is ensured that lantern ring 4 is steadily
It is located on knife handle 2.
2 outside of knife handle is also arranged restraining position ring block 16, is provided on stop collar 16 for stop collar 16 to be located in knife
Locating part 17 on handle 2, according to actual needs, locating part 17 equally can be screw element, and lantern ring 4 is located at cutterhead 1 and stop collar
Between 16, stop collar 16 is used for block lantern ring 4.After lantern ring 4 is located on knife handle 2, stop collar 16 is set in outside knife handle 2
Stop collar 16 is located on knife handle 2 by side using locating part 17, using 16 block lantern ring 4 of stop collar, prevents stop collar 16 along knife
The axial direction of handle 2 is mobile relative to knife handle 2.
The sliding of compensating part 6 is installed in compensation hole 8, and one end of compensating part 6 is provided with spherical extrados 18, and arc is blind
The inner wall of slot 9 is for contradicting the spherical intrados on spherical extrados 18；When rotating column 5, spherical extrados 18
Opposite sliding occurs between the spherical intrados of arc shaped blind slot 9, has compared to compensating part 6 for contradicting in arc shaped blind slot 9
Inner wall on plane, substantially reduce frictional force between compensating part 6 and column 5, squeeze column 5 easily
It is mobile to push away compensating part 6, on the other hand can reduce the abrasion between column 5 and compensating part 6, extends the service life of the two.
From one end of the arc shaped blind slot 9 to the other end of arc shaped blind slot 9, the width of arc shaped blind slot 9 gradually broaden or by
Gradual change is narrow, it is contemplated that one end of compensating part 6 is spherical extrados 18, limits spherical extrados using the side wall of arc shaped blind slot 9
18, prevent the width direction of the arcuately blind slot 9 of compensating part 6 from swinging back and forth.
The cutterhead 1 is equipped with benchmark plane of a loop 19 close to one end of lantern ring 4, and compensating part 6 is provided with for contradicting in base
Calibration plane 21 in lead ring plane 19, it is preferable that the central axis upright of benchmark plane of a loop 19 and cutterhead 1 is arranged, and works as cylinder
After part 5 drives compensating part 6 to contradict on cutterhead 1, calibration plane 21 is contradicted on benchmark plane of a loop 19, when the center of knife handle 2
The central axis of axis and machine tool chief axis compensate to it is substantially conllinear when, utilize the face between calibration plane 21 and benchmark plane of a loop 19
Face contact, it is ensured that compensating part 6 steadily contradicts on cutterhead 1, prevents between compensating part 6 and cutterhead 1 due to point contact or line contact
Cause the two contact unstable.
The knife handle 2 includes the base portion connecting with cutterhead 1, the clamping portion connecting with base portion, and clamping portion is for carrying the external world
Cutter, lantern ring 4 is set in the outside in clamping portion, and in a ring, compensation gap 3 is arranged around clamping portion in compensation gap 3.This implementation
In example, cutterhead 1 is equipped with the perforation through cutterhead 1, and clamping portion stretches out base portion via perforation, between clamping portion and the side wall of perforation
Form compensation gap 3.
The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as
Limitations of the present invention.
