Description
Technical field
The present invention relates to cutting tool field, the removable rack type cutter of more particularly, to a kind of cutter head.
Background technology
Cutter is the instrument being used for machining in machine-building, also known as cutting element.Most of cutter is that machine is used
, but also have handss.Because used in machine-building, cutter is substantially all for cutting metal material, so " cutter "
Word is typically just interpreted as metal cutting tool.
Rack type cutter is the cutter processing straight-tooth, helical teeth and herringbone bear by generating principle.The profile of rack type cutter much like tooth bar,
So also referred to as rack cutter.Rack type cutter has straight-tooth and two kinds of helical teeth.Straight-tooth rack type cutter is mainly used in processing straight-tooth gear and tiltedly
Gear；Skewed tooth combing tool is mainly used in processing the very narrow duplicate gear of herringbone bear, undercut and shouldered helical gear.
Rack type cutter is the important component part of cutting processing system, is the key factor of impact product quality.Batch production
During, rack type cutter performance can increase with use time and gradually degenerate, and then affects crudy it is therefore necessary to enter to cutter
Row is changed to avoid the occurrence of major quality loss.However, in cutter changing, needing to be changed whole cutter.Entirety is more
Tool changing has, and program is complicated, and frequently cutter changing can cause a large amount of production disruptions, reduces useful efficiency, increases the cost of charp tool.
By cutter integral replacing, waste serious, production cost can be increased.And, the replacement cycle is long and can increase the general of cutter fault
Rate, and then increase extra maintenance cost.
Content of the invention
Instant invention overcomes the deficiencies in the prior art, provide a kind of cutter head can be individually replaced, cost-effective and replacing construction
Rack type cutter.
For solving above-mentioned technical problem, the present invention employs the following technical solutions:
A kind of removable rack type cutter of cutter head, including cutter hub and cutter head, described cutter hub is provided with mounting seat, described cutter head
On be provided with some blades, the tool cutting edge angle of described blade is 60 °～70 °, and the auxiliary angle of described blade is -13 °～-5 °, described
Installing hole and arch posting are provided with mounting seat.
As the preferred version of the present invention, described cutter hub is provided with cutter hub connecting portion, described cutter head is away from the one of blade
End is provided with cutter head connecting portion, and described cutter hub connecting portion and cutter head connecting portion are by some bolt connections.
As the preferred version of the present invention, between described cutter hub connecting portion and cutter head connecting portion, it is provided with pad.
As the preferred version of the present invention, two groups of described installation seat, two groups of mounting seats are respectively arranged at the two ends of cutter hub.
As the preferred version of the present invention, the tool cutting edge angle of described blade is 65 °.
As the preferred version of the present invention, the auxiliary angle of described blade is -9 °.
Compared with prior art, the invention has the beneficial effects as follows:
The 1st, installing hole and arch posting are provided with the mounting seat of the present invention, it is firm to install, are avoided that rack type cutter works
During loosen, lead to cutter easily damaged.Cutter is impaired and frequently change cutter, cause less efficient, cost to improve.The present invention
Cutter hub connecting portion and cutter head connecting portion by some bolt connections, when needing to change cutter head it is only necessary to turn on bolt, change
Cutter head.The present invention does not need to change whole cutter, it is to avoid loaded down with trivial details step during integral replacing cutter, and when can save replacing
Between, improve efficiency.Only change cutter head, it is to avoid the waste of cutter hub, can be cost-effective.
