Abstract
The utility model discloses a kind of reversed counterbore machinery knives, it is intended to solve the deficiency of counter sink process operation inconvenience of the conventional tool to some narrow space positions.The utility model includes cutter head, knife handle, cutter head is arranged on knife handle lower end outer wall, lateral surface on cutter head far from knife handle is cutting face, incisal bevel is obliquely installed, cutting face is equipped with blade far from the one side edge of knife handle, on knife handle and cutter head side junction is equipped with chip space, and chip space and blade are separately positioned on the both sides of the edge of cutter head leading flank.When counter sink machines, the cutter head end of cutter is inserted into from counter sink miner diameter end, and after cutter head enters counter sink large diameter portion, transverse shifting cutter is overlapped knife handle axis with countersunk head axially bored line, and then cutter rotation is machined out counter sink.This reversed counterbore machine adds cutter very convenient to the counter sink process operation of some narrow space positions.
Description
Technical field
The utility model relates to a kind of cutters, more specifically, it relates to a kind of reversed counterbore machinery knives.
Background technique
With the continuous development of mechanical technology, in recent years, China's Tool and Die Technology has to develop on a large scale very much, mold manufacture level
There is large increase, advanced numerically-controlled machine tool instead of many processing stations for needing spark discharge, not only reduces
Because of positioning accuracy error caused by frequently dismounting, while mold manufacturing time is shortened, improves unit product processing efficiency.But
It is since most of mold cavity is complex, during changing processing technology, for some special machining positions, it is necessary to match
Process is just able to achieve with dedicated tool.When such as processing large-scale bottle blowing die part, because of the fixed counter sink in side and sides adjacent
Hypotelorism between wall causes processing space insufficient, and conventional tool is inconvenient countersunk head hole machined.
Utility model content
The utility model overcomes the deficiency of counter sink process operation inconvenience of the conventional tool to some narrow space positions,
A kind of reversed counterbore machinery knives are provided, it is very convenient to the counter sink process operation of some narrow space positions.
In order to solve the above-mentioned technical problem, the utility model uses a kind of following technical scheme: reversed counterbore machinery knives,
Including cutter head, knife handle, cutter head is arranged on knife handle lower end outer wall, and the lateral surface on cutter head far from knife handle is cutting face, incisal bevel
It is obliquely installed, cutting face is equipped with blade far from the one side edge of knife handle, and on knife handle and cutter head side junction is equipped with chip space, row
Bits slot and blade are separately positioned on the both sides of the edge of cutter head leading flank.
When counter sink machines, the cutter head end of cutter is inserted into from counter sink miner diameter end, and cutter head enters counter sink large diameter portion
Afterwards, transverse shifting cutter certain distance, then cutter rotation are machined out counter sink.Cutting of being obliquely installed is arranged in blade
On bevel, be conducive to reduce cutting resistance, cutting effect is good, and chip space is convenient for the discharge of chip, prevents chip from damaging processing table
Face.This reversed counterbore machinery knives are very convenient to the counter sink process operation of some narrow space positions.
Preferably, blade and knife handle axis are arranged in parallel.It avoids the formation of hole wall and connects knife, while optimizing anterior angle, avoid knife
Head in process tipping or cross quick-wearing, improve cutting-tool's used life.
Preferably, cutter head trailing flank and knife handle outer wall are tangent, the thickness between cutter head leading flank and trailing flank is less than knife
The diameter of handle and the radius for being greater than knife handle.This structure setting is conducive to improve in cutting process, cutter head and knife handle link position
Anti-twisting property.
Preferably, cutter head upper side is obliquely installed from knife handle connecting pin to the other end upward.Cutter head when avoiding processing
Upper side and face contact to be processed reduce cutting resistance.
Preferably, cutter head leading flank is obliquely installed from knife handle connecting pin to the other end forward.This structure setting by
Work surface is flowed to through chip space in chip, improves counterbore surface finish.
Preferably, the knife handle lower end outer wall opposite with cutter head is equipped with the arc dust lead face being obliquely installed, arc dust lead
Face is obliquely installed to close to knife handle axis direction from top to bottom, and the angle of arc dust lead face and knife handle axis is to close to chip space side
To gradually increasing.Dust lead face provides more spaces to the discharge of chip, conducive to the quick discharge of chip.
Preferably, knife handle lower end surface is concordant with cutter head lower end surface.Prevent knife handle lower end and other components in process
It interferes.
Compared with prior art, the utility model has the beneficial effects that (1) reversed counterbore machinery knives are to some narrow skies
Between position counter sink process operation it is very convenient；(2) cutter use process chip removal effect is good, will not damage finished surface；(3)
Cutter life is long.
