The limiting slot 9 in 7 left side of fixing groove, the inside of the limiting slot 9 are equipped with locating part 10.
The expansion piece 4 includes expansion loop 401, and the expansion loop 401 is socketed with the external of cutter hub 1, the expansion loop 401
Inner surface offer anti-channeling slot 402, the anti-channeling slot 402 is clamped with anti-channeling tooth 3, is limited to expansion piece 4, is made expansion piece
It will not be slided between 4 and cutter hub 1, the outer surface of the expansion loop 401 is equipped with limiting tooth 403, the limiting tooth 403 and limiting slot
6 clampings, limit cutter ring 5, make to slide between cutter ring 5 and expansion piece 4.
The fixing piece 8 includes fixing clasp 801, and the fixing clasp 801 is clamped with fixing groove 7, plays fixed function, makes
Expansion piece 4 can be fixed on the outside of cutter hub 1, and the left side of the fixing clasp 801 is equipped with guiding tooth 802, play guiding and make
With.
The top surface of the fixing piece 8 is obliquely arranged, and the left end of 1 lateral surface of cutter hub is obliquely arranged, and solid
The gradient for determining 8 top surface of part is identical as the gradient of 1 top surface of cutter hub, play the guiding role, and enables what cutter ring 5 was more easier to be arranged
It is convenient that installation and replacement are carried out to cutter ring 5 in the outside of expansion piece 4.
The locating part 10 includes limited location snap ring 1001, and the limited location snap ring 1001 is clamped with limiting slot 9, the limiting card
The left side of ring 1001 offers pilot hole 1002, and the pilot hole 1002 is adapted with guiding tooth 802, and the pilot hole
1002 are socketed with guiding tooth 802, and the right side of the limited location snap ring 1001 is equipped with crushing block 1003, play position-limiting action, make cutter ring 5
It is fixed on the outer surface of expansion piece 4, the top surface of 1002 inner cavity of pilot hole and the bottom surface of crushing block 1003 are oblique, and its
Gradient is identical as the gradient of 8 top surface of fixing piece.
The length value and width value of the pilot hole 1002 are all larger than the length value and width value of guiding tooth 802, make to be oriented to
There are a buffer gaps between hole 1002 and guiding tooth 802, convenient to install to locating part 10, thus convenient to cutter ring 5
Installation and replacement are carried out, while ensuring that the right end of crushing block 1003 is preferentially contacted with cutter ring 5, guarantee that cutter ring 5 is compacted.
The linear expansion coefficient when expansion piece 4 is heated is greater than linear expansion coefficient when cutter ring 5 is heated, and makes expansion piece
The amount of 4 linear expansions is greater than the amount of 5 linear expansion of cutter ring, by between cutter ring 5 and expansion piece 4 gap and expansion piece 4 and cutter hub 1
