Brief description of the drawings
Fig. 1 is the front view of trapezoidal slotting cutter provided by the invention.
Fig. 2 is the right view of trapezoidal slotting cutter provided by the invention.
Fig. 3 is the structural representation of straight sword blade in trapezoidal slotting cutter provided by the invention.
Embodiment
The present invention provides a kind of trapezoidal slotting cutter, to make the purpose of the present invention, technical scheme and effect clearer, bright
Really, developing simultaneously referring to the drawings, the present invention is described in more detail for embodiment.It should be appreciated that specific implementation described herein
Example is not intended to limit the present invention only to explain the present invention.
Fig. 1 to Fig. 3 is referred to, the present invention provides a kind of trapezoidal slotting cutter.For the ease of observing cutter head structure, Fig. 1 and Fig. 2
In be to draw straight sword blade, but individually draw straight sword blade in figure 3.
A kind of trapezoidal slotting cutter, including handle of a knife 1, the cutterhead being coaxially disposed with handle of a knife, and the knife being arranged on cutterhead
Piece 3, cutterhead includes a circular body 21, and is symmetricly set on two round platforms 22 of body both sides, the side of each round platform
Some straight sword blades 3 are detachably provided with face respectively；The blade of each straight sword blade of cutterhead the same side with perpendicular to knife
The angle of the plane of disk axis 11 is equal, and the blade of each straight sword blade of cutterhead the same side can rotate around the axis 11 of cutterhead
Form the complete surface of revolution.In other words, in front view, the surface of revolution that each blade of the cutterhead per side is formed is respectively one
Frusto-conical face（Herein, frusto-conical face refers to removes truncated cone with a plane parallel to circular cone bottom surface, between bottom surface and section
Part side）.Therefore, when cutterhead rotates, the blade of cutterhead both sides can be used for the both sides inclined-plane of processing dovetail groove.
During actual use, the trapezoidal slotting cutter can carry out finish-milling to the dovetail groove rough milled.Compared to common dovetail groove milling
The cutter head of knife, the cutterhead size and weight of milling cutter provided by the invention are bigger, therefore rotate more stable and can bear bigger
Cutting resistance；Simultaneously as two sides of cutterhead can set more straight sword blades, therefore cutting precision is higher, so as to real
Now high-precision dovetail groove at cutting.
Further, in the projection perpendicular to the plane of cutter axis（As shown in right view）, cutterhead is straight per side
Angle of throat piece concentrically annular configuration, it is along the circumferential direction equiangularly disposed respectively in the inner ring and outer rings per side to have multiple straight swords
Blade.Straight sword blade is not drawn in Fig. 2, annular configuration is only depicted in the mounting groove 221 of inner ring and is arranged in the peace of outer shroud
Tankage 222, and each blade is then fixed in mounting groove 221 and 222 when actually using.Rotated by the setting cutterhead
Each blade in journey in same ring can be contacted by identical time interval with workpiece, ensure that workpiece is equably cut
Cut.The straight sword blade of the same side is arranged to two rings, the size of single blade can be caused to reduce, is only needed more after blade damage
Change a less blade, thus avoid as prior art by blade set very big and blade sets very long, i.e.,
Blade damage very little is set also to fall a very big blade exchange.
Further, in the projection perpendicular to the plane of cutter axis, the inner ring and outer rings of cutterhead the same side set phase
With the straight sword blade of quantity, the straight sword blade of the inner ring and outer rings of cutterhead the same side shifts to install in a circumferential direction.Pass through mistake
Position is set so that the moment that each blade of inner ring and outer rings contacts with workpiece is not simultaneously, i.e. cutter be instantaneously subject to always
Cutting resistance is reduced, and improves the service life of milling cutter.
Further, in the projection perpendicular to the plane of cutter axis, each straight sword blade position of two inner ring of cutterhead
Put identical；Each straight sword blade position of two outer shrouds of cutterhead is identical.The setting causes the symmetrical configuration of blade both sides, is easy to add
Work.
Further, each specification of straight sword blade 3 on cutterhead is identical, so as to improve the interchangeability of straight sword blade, drop
Maintenance, repair cost during the low cost of manufacture of milling cutter and follow-up use.
Preferably, as shown in Fig. 2 being respectively arranged with 5 straight sword blades in inner ring and outer rings of the cutterhead per side.
As shown in figure 3, further, the body of each straight sword blade 3 is cuboid, is divided on four ribs 301 of cuboid
A blade is not provided with.Because each straight sword blade has four blades respectively, therefore, can switch after an edge wear
Using another blade, until the straight sword blade that four blades more renew again after all wearing.
Further, each straight sword blade 3 is corresponded on cutterhead and offers a mounting groove respectively（Marked as 221 Hes in Fig. 2
222）, discharge launder 223 and abacus 224；Each blade is respectively by screw lock in corresponding mounting groove；Perpendicular to
Abacus corresponding to the side position identical any two blade of cutterhead two is interconnected in the projection of the plane of cutter axis.Tool
Body, a through hole is offered on the body of straight sword blade, installation trench bottom offers a screwed hole, and screw passes through through hole simultaneously
In screwed hole corresponding to being screwed into.
Further, axially extending bore is offered in the middle part of cutterhead, that one end that handle of a knife corresponds to cutterhead offers screwed hole, cutterhead
It is bolted with handle of a knife.
The axially extending bore opened up in the middle part of cutterhead includes the first through hole 231 coaxially opened up with cutterhead, and four are equably divided
Second through hole 232 of the portion around first through hole；That one end that handle of a knife corresponds to cutterhead correspondingly offers five screwed holes（In figure
It is not shown）, first through hole and each second through hole branch are connected through bolt with handle of a knife.By unrooted bolt connection, ensure that
Blade and handle of a knife firmly connect.
It is understood that for those of ordinary skills, can be with technique according to the invention scheme and its hair
Bright design is subject to equivalent substitution or change, and all these changes or replacement should all belong to the guarantor of appended claims of the invention
Protect scope.
