Maximum cost-effective, cutting-tool's used life should extend as far as possible.
Utility model content
In order to overcome defect and deficiency present in above-mentioned prior art, this utility model provides a kind of shield machine and rolls
Cutter, hobboing cutter of the present utility model ensure that stability in the course of the work and reliability, adds the life-span of hobboing cutter, reduces
Production cost.
In order to solve above-mentioned problems of the prior art, this utility model is achieved through the following technical solutions:
A kind of hob cutter for shield machine, including hobboing cutter body and cutter ring, it is characterised in that: if radially the offering of described cutter ring
Dry radial hole, is provided with alloy block in described radial hole, described alloy block one end protrudes from cutter ring outer surface, described alloy block
The other end slidably connect regulating block, described regulating block and radial hole threaded engagement, described regulating block and alloy block generation phase
To rotation, regulating block moves up and down in radial hole with radial hole threaded engagement, thus drives alloy block to move up and down.
A fixed block, the lateral surface of described fixed block and hobboing cutter body it is installed with on the peripheral hobboing cutter body of described cutter ring
Lateral surface maintains an equal level.
One layer of wearing layer it is coated with on described fixed block.
One layer of wearing layer it is coated with on described cutter ring.
The upper surface of described fixed block uses the excessive face of arc or wedge shape transition face.
Compared with prior art, useful the having the technical effect that this utility model is brought
1, this utility model is radially spaced on cutter ring along cutter ring and offers and some radial holes, is provided with conjunction in radial hole
Gold bullion, and alloy block protrudes from cutter ring outer surface, and the other end of alloy block connects regulating block, and regulating block is by screw thread even
Being connected in radial hole, by rotating regulating block, under the effect of screw thread, regulating block moves up and down in radial hole, thus drives
Alloy block moves up and down.When alloy block may wear to a certain degree on cutter ring, alloy can be regulated by regulating regulating block
The extension elongation of block, adds hobboing cutter service life, and alloy block and regulating block is slidably connected, regulating block and alloy block generation phase
To rotation, it is ensured that the rotation of regulating block is not affected by alloy block, it is ensured that hobboing cutter stability in the course of the work and can
By property.Structure of the present utility model ensure that stability in the course of the work and reliability, adds the life-span of hobboing cutter, fall
Low production cost.
2, this utility model also card dress fixed block on the peripheral hobboing cutter body of cutter ring, can effectively protect hobboing cutter body, it is to avoid
The generation of hobboing cutter body wear phenomenon.Fixed block can be replaced in the case of serious wear, it is to avoid cause due to abrasion
Hobboing cutter body entirety scraps phenomenon, effectively extends the service life of hobboing cutter body.
3, this utility model also spraying abrasion-proof layer on cutter ring and fixed block, extends the service life of hobboing cutter further.
