Description
Technical field
The present invention relates to metal cutting technology field, more particularly to a kind of grooving cutter.
Background technology
In metal cutting process industry, in cut-out, grooving process blade by very big cutting force, produce compared with
Big cutting vibration, it is generally the case that clamping of the cutter to blade concentrates on blade close to cutting edge part, makes in working angles
Middle blade rear end vibration is big, and clamping reliability is not high, and cutter is also easy to produce abrasion and deformed, and influences part processing precision.
United States Patent (USP) US6234727B1 discloses a kind of cutting tool, and the clamping surface of cutter first can be around the rotated
One resilience axes resilient movement, the second clamping surface can be around the second resilience axes resilient movement rotated, the first clamping surface
Clamping force is applied to the top front end of blade, the second clamping surface applies clamping force to the upper rear end of blade, only when first
When resilience axes are conllinear with the second resilience axes, the first clamping surface and the second clamping surface are just separate, if rotate
First resilience axes and the second resilience axes are not conllinear, then the first clamping surface and the second clamping surface be not separate, solely
Vertical degree depends on the close degree of the first resilience axes and the second resilience axes, and this is received to the structure of cutter and blade
Very big limitation, while clamping reliability is ensured, it is difficult to ensure that the complete independence of two clamping surfaces.
The content of the invention
The technical problem to be solved in the present invention be overcome the deficiencies in the prior art there is provided the simple in construction, clamping of one kind it is stable,
Support strength is high, a kind of grooving cutter of multiple spot clamping positioning.
In order to solve the above technical problems, the present invention uses following technical scheme：
A kind of grooving cutter, including blade and cutter hub, cutter hub include support section and clamping part, support section and clamping
