Abstract

The invention discloses a tool used for machining ladder holes. The tool comprises a tool body, a large-opening tool bit arranged on the tool body and a small-opening tool bit arranged on the large-opening tool bit. The tool body, the large-opening tool bit and the small-opening tool bit are coaxially arranged in sequence. The large-opening tool bit comprises a big rod body and a plurality of large-opening blades arranged on the periphery of the big rod body in a surrounding mode. The small-opening tool bit comprises a small rod body and a plurality of small-opening blades arranged on the periphery of the small rod body in a surrounding mode. A chamfer blade is arranged between the large-opening blades and the small-opening blades. The chamfer blade forms a 45-degree included angle with the rod wall of the small rod body. The chamfer range of the chamfer blade is 0.5-2 mm. The tool used for machining the ladder holes is simple in structure; burrs can be directly removed through the tool, and the production efficiency is improved.

Description

A kind of cutter for processing shoulder hole
Technical field
The present invention relates to a kind of cutter, be specifically related to a kind of cutter for processing shoulder hole.
Background technology
At present, shoulder hole cutter used in process comprises cutter hub and cutter head, needs first to carry out macropore 6 with the cutter that tool bit diameter is larger and processes, and then the cutter utilizing tool bit diameter less carries out aperture 7 and processes, thus forms shoulder hole.After cutter boring, the intersection place of macropore and aperture easily leaves burr, needs artificial removal, wastes time and energy, reduce production efficiency.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of cutter for processing shoulder hole, utilize this cutter directly can remove burr, enhance productivity.
For achieving the above object, the invention provides following technical scheme:
For a cutter for processing shoulder hole, comprise cutter hub, the macropore cutter head be arranged on cutter hub, the aperture cutter head be arranged on macropore cutter head, described cutter hub, macropore cutter head, aperture cutter head are coaxially arranged successively.
Described macropore cutter head comprises the large body of rod and around the some macropore blades be arranged on around the large body of rod; Described aperture cutter head comprises rhabdites and around the some aperture blades be arranged on around rhabdites; Described macropore blade is identical with aperture blade quantity, and described macropore blade and aperture blade are wholely set and form stepped.
Be provided with chamfering blades between described macropore blade and aperture blade, the bar wall structure angle at 45 ° of this chamfering blades and rhabdites, the chamfering scope of this chamfering blades is 0.5 ~ 2mm.
Further, also comprise the flat cutter head of ream for the flat outer surface of ream, the flat cutter head of described ream is mutually vertical with cutter hub, and described cutter hub is provided with some installing holes for installing the flat cutter head of ream, the flat cutter head of described ream comprises department of assembly and blade, and described department of assembly is equipped with in installing hole.
Beneficial effect of the present invention is:
A kind of cutter structure for processing shoulder hole of the present invention is simple, utilizes this cutter directly can remove burr, and can make shoulder hole one-shot forming, improve production efficiency.
Accompanying drawing explanation
In order to make object of the present invention, technical scheme and beneficial effect clearly, the invention provides following accompanying drawing and being described:
Fig. 1 is the structural representation of shoulder hole;
Fig. 2 is structural representation of the present invention;
Fig. 3 is the enlarged diagram of chamfering blades.
Wherein: 1-cutter hub, 2-macropore cutter head, 3-aperture cutter head, the flat cutter head of 4-ream, 5-chamfering blades, 6-macropore, 7-aperture, 11-installing hole, 21-macropore blade, 31-aperture blade, 41-department of assembly, 42-blade.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
A kind of cutter for processing shoulder hole of the present invention, comprises cutter hub 1, the macropore cutter head 2 be arranged on cutter hub 1, the aperture cutter head 3 be arranged on macropore cutter head 2, and described cutter hub 1, macropore cutter head 2, aperture cutter head 3 are coaxially arranged successively.
Described macropore cutter head 2 comprises the large body of rod and around the some macropore blades 21 be arranged on around the large body of rod; Described aperture cutter head 3 comprises rhabdites and around the some aperture blades 31 be arranged on around rhabdites; Described macropore blade 21 is identical with aperture blade 31 quantity, and described macropore blade 21 is wholely set with aperture blade 31 and forms stepped.
Be provided with chamfering blades 5 between described macropore blade 21 and aperture blade 31, the bar wall structure angle at 45 ° of this chamfering blades 5 and rhabdites, the chamfering scope of this chamfering blades 5 is 0.5 ~ 2mm.
A kind of cutter for processing shoulder hole of the present invention, structure is simple, during processing shoulder hole, utilizes the chamfering blades between macropore blade and aperture blade can carry out chamfering to the intersection of macropore and aperture, reaches the effect of burr removing.Chamfering blades chamfering scope is 0.5 ~ 2mm, can make the chamfering of final molding within the scope of 0.5 ~ 2mm.
As the improvement of such scheme, also comprise the flat cutter head 4 of ream for the flat outer surface of ream, the flat cutter head of described ream 4 is mutually vertical with cutter hub 1, described cutter hub 1 is provided with some installing holes 11 for installing the flat cutter head 4 of ream, the flat cutter head 4 of described ream comprises department of assembly 41 and blade 42, and described department of assembly 41 is equipped with in installing hole 11.
Concrete, this installing hole 11 is taper hole, identical with taper hole form during existing cutter tool changing.And each installing hole 11 points is different in cutter hub 1 position axially.
In the present embodiment, after shoulder hole machines, can flat for ream cutter head 4 be assemblied on cutter hub 1, ream be carried out to macropore upper surface and puts down, meanwhile, can flat for ream cutter head 4 can be arranged in different installing holes 11 according to demand, ream be carried out to different shoulder hole outer surfaces and puts down.
What finally illustrate is, above preferred embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although by above preferred embodiment to invention has been detailed description, but those skilled in the art are to be understood that, various change can be made to it in the form and details, and not depart from claims of the present invention limited range.
