Description
Technical field
The utility model is related to numerical control machining cutter equipment field, especially a kind of coarse-fine processing facing cutter structure.
Background technology
Existing numerical control machining cutter is when processing die casting cast gate, burr cloak, due to the defect of structure design,
It generally requires to be processed twice, processing efficiency is low.There is no currently on the market can also carry while improving processing efficiency
The milling cutter disc apparatus of high processing quality.
Utility model content
The technical problem to be solved by the utility model is to provide one kind time processing may be implemented thick, finishing can be completed
The coarse-fine processing facing cutter structure of work.
Technical solution adopted by the utility model to solve its technical problems is：Coarse-fine processing facing cutter structure, including
Cutter hub is evenly arranged at least one heavy-duty cutter and at least one finishing cutter in the side wall surface of the cutter hub, wherein
The central axis rotation of the heavy-duty cutter and finishing cutter with cutter hub and around cutter hub, the rotation of the heavy-duty cutter
The diameter of track is more than diameter of the finishing cutter around the rotational trajectory of cutter hub.
Further, the heavy-duty cutter is by the knife bar that is set in the side wall surface of cutter hub and is set to knife bar end
The heavy-duty cutter blade of head is constituted.
Further, the finishing cutter is by the knife bar that is set in the side wall surface of cutter hub and is set to knife bar end
The finishing cutter blade of head is constituted.
Further, the blade shapes of the heavy-duty cutter blade or finishing cutter blade are equilateral triangle.
Further, the heavy-duty cutter blade or finishing cutter blade are set to knife bar by blade screw
End.
Further, being evenly arranged with fan-shaped loss of weight pore structure around the central axis of cutter hub on the cutter hub.
Further, being provided with bar shaped step pore structure on the cutter hub.
The utility model has the beneficial effects that：In actual use, due to the diameter for the rotational trajectory for stating heavy-duty cutter
More than finishing cutter around the diameter of the rotational trajectory of cutter hub, therefore, heavy-duty cutter is completed first to the thick of workpiece to be processed
Processing, next, the finishing cutter then to follow up is completed to complete finishing at rough machined wall surface to be processed immediately
The efficiency of processing is greatly improved to complete the technique effect of " time processing completes Roughing and fine machining " in work, and
Influence of phenomena such as the effectively preventing the shake knife often occurred in conventional machining process to product quality.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model bottom.
Fig. 2 is the schematic diagram at the top of the utility model.
In figure label for：Cutter hub 1, knife bar 2, knife bar fixing screws 3, blade edge 4, blade screw 5, fan-shaped lightening hole knot
Structure 11, bar shaped step pore structure 12.
Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and examples.
Coarse-fine processing facing cutter structure as shown in Figure 1 and Figure 2, including cutter hub 1, in the side wall surface of the cutter hub 1 uniformly
It is provided at least one heavy-duty cutter and at least one finishing cutter, wherein the heavy-duty cutter and finishing cutter
It is rotated with cutter hub 1 and around the central axis of cutter hub 1, the diameter of the rotational trajectory of the heavy-duty cutter is more than finishing cutter
Around the diameter of the rotational trajectory of cutter hub 1.
The utility model cleverly designs the structure of facing cutter, due to heavy-duty cutter rotational trajectory it is straight
Diameter is more than diameter of the finishing cutter around the rotational trajectory of cutter hub 1, therefore, although heavy-duty cutter is respectively positioned on finishing cutter
On the same cutter hub 1, but heavy-duty cutter but can at first cut workpiece to be processed, next, due to finishing
4 need of blade edge of work milling cutter can be cut to the roughing face just cut by heavy-duty cutter can carry out essence at once
Processing.Such structure design not only realizes the technique effect of " time processing completes Roughing and fine machining ", moreover, in structure
On be provided with according to needs of production and the basis of the respective cutting output of flexible modulation heavy-duty cutter and finishing cutter, can be with
Well adapt to the cutting demand of different product.
In general, in order to simplify the structure of milling cutter, to effectively reduce cost, such scheme can be selected：It is described thick
Milling cutter processing is by the knife bar 2 that is set in the side wall surface of cutter hub 1 and the heavy-duty cutter blade structure for being set to 2 end of knife bar
At；Likewise, the finishing cutter can also be selected by the knife bar 2 that is set in the side wall surface of cutter hub 1 and be set to knife
The finishing cutter blade of 2 end of bar is constituted.In conjunction with the processing experience of practice, the preferably described heavy-duty cutter blade or finishing
The blade shapes of cutting plate for milling cutters are equilateral triangle.
In addition, in order to realize the convenient installation and removal of blade, as shown in Fig. 2, such scheme can be selected：It is described thick
Milling cutter processing blade or finishing cutter blade are set to 2 end of knife bar by blade screw 5.Such structure design allows this
Utility model is provided with greater flexibility, so as to expand the range of application, improves utilization rate of equipment and installations.
It in actual use,, can be in the knife to reduce the heavy burden to lathe handle of a knife in order to reduce by 1 mass of cutter hub
Central axis on body 1 around cutter hub 1 is evenly arranged with fan-shaped loss of weight pore structure 11.In general, it is preferred that being arranged on the cutter hub 1
Bar shaped step pore structure 12, to realize the tight fit with lathe handle of a knife.
Embodiment
Using universal cutter and utility model cutter parameters statistical form
It can be obtained from upper table, before using the utility model cutter, the rotating diameter of cutter isAnd it needs
To be cut twice by Roughing and fine machining (identical program track needs circulation primary), eventually lead to efficiency reduce (105/class/
8H), and since the cast gate of portioned product, burr cloak are excessive, causing cutter to occur shake knife phenomenon in milling process causes
Qualification rate is low (86.1%)；After using utility model cutter, the rotating diameter of cutter reachesAnd Roughing and fine machining
It is disposable to complete, and without there is similar shake knife phenomenon, it is also effective while improving class's yield (182/class/8H)
Qualification rate (99.2%) is improved, production cost has been saved.
