Two milling cutters 42 described in horizontal line have certain spacing in vertical direction, in the present embodiment, the spacing is equal to
Or greater than 1.5 millimeters and it is less than or equal to 3 millimeters it should be noted that four above-mentioned 42 structures of milling cutter, specifications are the same.
In other embodiments, when the quantity difference of the milling cutter 42, the level that milling cutter 42 can be arranged according to specific circumstances is high
Degree, wherein the level height of multiple milling cutters 42 can all it is identical can also be different, can also part it is identical, part not
Same set-up mode.It is appreciated that constituting the successive suitable of cutting contact point by the design that 42 horizontal line of milling cutter misplaces
Sequence guarantees wherein a group or a milling cutter 42 cut in advance is responsible for clear angle, and then avoids colliding with each other between the milling cutter 42
Do not occur arc fillet when cutting polygonal hole.
Further, the quantity of the main shaft bevel gear 3 can be one or more, will transmit with each main shaft bevel gear 3
Multiple cutting mechanisms 4 of connection are one 4 groups of cutting mechanism, and the present invention may also set up the multiple and main shaft bevel gear 3 one by one
4 groups of corresponding cutting mechanism, it is deeper that the setting of 4 groups of multiple cutting mechanisms and the main shaft bevel gear 3 can form depth
Polygonal hole, some burrs, clast etc. can also be removed, further the smooth wall surface of the polygonal hole, further increased
The quality for being formed by polygonal hole is added.
The embodiment of the invention provides a kind of polygonal hole processing methods, using above-mentioned polygonal hole processing unit (plant), institute
The method of stating includes:
Step (1): the drilling rod 1 drives drill bit 2 to rotate, and main shaft bevel gear 3 is driven to rotate, the main shaft bevel gear 3
Its corresponding multiple horizontal axis bevel gear 41 is driven to rotate, the multiple horizontal axis bevel gear 41 drives multiple milling cutters 42 connected to it
Rotation, the drilling in advance of drill bit 2.
Step (2): the multiple milling cutter 42 then cuts the wall surface of inner hole, forms polygonal hole.
It is appreciated that the present invention is by being provided with main shaft bevel gear 3 close to the position of the drill bit 2 in the drilling rod 1, together
When multiple cutting mechanisms 4 are set milling cutter 42 knife face where plane surround multi-faceted column, the horizontal axis bevel gear 41
It is engaged with the main shaft bevel gear 3, when the drilling rod 1 rotation, passes through the main shaft bevel gear 3 and the horizontal axis bevel gear 41
Axial direction rotation of the milling cutter 42 around the milling cutter 42 is driven, and then after the drill bit 2 forms circular hole or conical bore, Duo Gesuo
It states milling cutter 42 and carries out secondary operation in the wall surface of the circular hole, and then form polygonal hole, structure is simple, easy to operate and cost
It is low.
Further, in other embodiments, after completing the step (1), the drill bit 2 can be laid down, that is, will
The drill bit 2 is separated on the drilling rod 1, and then the multiple milling cutter 42 then cuts the drill bit 2 and is formed by hole again
Wall surface, and then form polygonal hole, it will be understood that inner hole is cut by the milling cutter 42 again later by laying down the drill bit 2
Wall surface can occur to avoid the drill bit 2 and drilling collision or the case where Caton.In other embodiments, if it exists
Existing round hole or bellmouth need to be processed into polygonal hole, can also directly lay down the drill bit 2, described in driving
Milling cutter 42 rotates, while can also adjust its length according to the telescopic connecting shaft 43, and then match existing circle
The size of shape hole or bellmouth.
Further, although preferred embodiments of the present invention have been described, but those skilled in the art once learn
Basic creative concept, then additional changes and modifications may be made to these embodiments.So appended claims are intended to solve
It is interpreted as including preferred embodiment and all change and modification for falling into the scope of the invention.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
Mind and range.In this way, if these modifications and changes of the present invention belongs to the range of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to include these modifications and variations.
