Specific embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present disclosure clearer, below in conjunction with the embodiment of the present disclosure
Attached drawing, the technical solution of the embodiment of the present disclosure is clearly and completely described.Obviously, described embodiment is this public affairs
The part of the embodiment opened, instead of all the embodiments.Based on described embodiment of the disclosure, ordinary skill
All other embodiment that personnel are obtained under conditions of without creative work belongs to the scope of disclosure protection.
At least one embodiment of the disclosure provides a kind of cutting element, for example, gear milling cutter 1 as shown in Figs 1-4,
The gear milling cutter 1 includes：Main body 10；The multiple dimples 20 being arranged in main body 10；Multiple blades 30, each blade 30 are set
In one in the multiple dimple 20；And multiple Wedge grippings 40, each Wedge gripping 40 are removably attached to
In one in the multiple dimple 20.Each dimple 20 has front 201, bottom surface 202 and side 203.Each blade
30 have rake face 301 and the rear knife face 302 opposite with rake face 301, which abuts with before dimple 20 201.
Each Wedge gripping 40 and compresses the blade 30 so that its rake face 301 abuts adjacent to the rear knife face 302 of respective blade 30
201 before dimple 20.
Dimple 20 is preferably alternately arranged on two faces of gear milling cutter 1, and the quantity of dimple and blade can basis
Concrete application occasion sets to set, such as according to power of lathe of the gear milling cutter etc. is installed.
Although showing that each Wedge gripping 40 includes two voussoirs in figure, it will be appreciated, however, by one skilled in the art that
Each Wedge gripping 40 can only include a voussoir, can also include more than two voussoirs.The quantity of voussoir can root
It is set according to the size of blade.
According to the gear milling cutter of the embodiment of the present disclosure, compared with integral cutter or welded type cutter, can by blade from
Carry out reconditioning is taken off on cutter hub, thus flexibility greatly improves, and also gear milling cutter can change new blade and continue to produce, from
And improve productivity.Further, Wedge gripping compresses blade from rear knife face, therefore when blade needs reconditioning, only needs reconditioning
Rake face, the reconditioning can even be can be realized with a flat-grinding machine, therefore grinding efficiency is high, at low cost.Moreover, reconditioning
The operation that blade afterwards is installed to cutter hub becomes simple, i.e. makes Wedge gripping from rear knife by adjusting Wedge gripping vertically
One side compression blade of face simultaneously makes the rake face of blade therefore ensure that the position of the rake face of blade is protected always against before dimple
It holds constant, and then remains unchanged cutting molded line.The design of blade, wedge shape are compressed from rake face accordingly, with respect to Wedge gripping
Fixture from rear knife face compress blade have the advantages that reconditioning step simplified, tool changing and to knife it is easy, ensure to cut molded line.
When installing blade, in order to ensure the rake face 301 of blade 30 is connected to 201 before dimple, Wedge gripping 40
One or more studs 401 may be employed to be fixed, so convenient for adjusting and compress.
Gear milling cutter 1 can also include multiple adjust pad components 50, each adjust pad component 50 is located at corresponding
Between Wedge gripping 40 and blade 30, and contacted with the rear knife face 302 of blade 30.By selecting the adjusting pad with suitable thickness
Sheet element 50, it can be ensured that blade 30 is preferably bonded 201 before dimple 20.When blade reconditioning number increase, blade
Thickness can reduce, and at this moment, only possibly can not compress blade 30 completely by the adjusting of Wedge gripping 40 itself, it is therefore desirable to will adjust
Whole shim member 50 is changed to the adjust pad component with bigger thickness.It, can be with by using this method and/or these components
Further increase blade reconditioning number, improve the utilization rate of blade, reduce cost.
However it is to be noted that adjust pad component 50 is not required, Wedge gripping 40 can directly abut blade 30
To realize the compression of blade, in such a case, it is possible to complete certain number using the regulated quantity of itself of Wedge gripping 40
Blade reconditioning.
Although in addition, show that each adjust pad component 50 includes two adjust pads, art technology in figure
Personnel will be understood that, similar with Wedge gripping 40, each adjust pad component 50 can only include an adjust pad, can also
Including more than two adjust pads.The quantity of adjust pad can be set according to the size of blade.
Gear milling cutter 1 can also include multiple pads 60, each gasket 60 is placed in each dimple 20 and is fixed to
Main body 10.Each gasket 60 has first surface 601 and second surface 602, and first surface 601 is located at the bottom surface of dimple 20
Between 202 and blade 30, second surface 602 is located between the side 203 of dimple 20 and blade 30.First surface 601 and second
Surface 602 together with before dimple 20 201, is provided as the positioning surface of blade 30, blade 30, which realizes three faces, to be determined
Position, it is ensured that high positioning accuracy.The width of gasket 60 is less than the thickness of blade 30.
It is noted that gasket 60 is not required, and when the machining accuracy of dimple is enough, 201, bottom before dimple 20
Face 202 and side 203 may be used as the positioning surface of blade 30.By setting gasket 60, it can compensate and dimple is processed on cutter hub
When the error that generates, and the installation site of each blade is accurately set, to obtain set cutting molded line.
Although the attached drawing of the disclosure shows gear milling cutter as an example, it will be understood by those skilled in the art, however, that this public affairs
The structure opened can be applied to rotor milling cutter.
At least one embodiment of the disclosure additionally provides a kind of blade clamping means.The blade clamping means include：It will
Blade 30 is placed in dimple 20；And with Wedge gripping 40 from the 302 1 side compression blade 30 of rear knife face of blade 30 so that
The rake face 301 of blade 30 is abutted 201 before dimple 20.
The blade clamping means can also include：By adjust pad component 50 be located in Wedge gripping 40 and blade 30 it
Between so that the adjust pad component 50 is contacted with the rear knife face 302 of blade 30.
It can easily be ensured that the position of the rake face of blade remains constant according to the blade clamping means of the disclosure,
And then the cutting molded line of cutter is remained unchanged, and it is easy to operate, it is efficient.
The above is only the exemplary embodiment of the disclosure, not for the protection domain of the limitation disclosure, this public affairs
The protection domain opened is determined by appended claim.
