Description
Technical field
A kind of tool for mechanical machining is the utility model is related to, more particularly to a kind of milling tools.
Background technology
In lathe process, the good product inner ring of preparatory processing does not reach the requirement of finish, it is necessary to continue to polish, and show
Some modes are polished by way of manually taking and drawing, but this mode is polished, difficulty is big, and and its labor intensive.
The content of the invention
The utility model proposes a kind of annular groove mill for being easy to polishing inner ring.
A kind of annular groove mill described in the utility model, including sleeve and inner support core rod, the sleeve are round platform sleeve, its
Inner hollow, the big end of the round platform sleeve are provided with an outstanding annulus fin, and the annulus fin surface is smooth, and its is small
End is fixed with a hollow handle, and the handle inwall is provided with internal thread；Symmetrically it is provided with a pair and lacks on the round platform sleeve
Plane where big end is averagely divided into two symmetrical sectors by oral area, two notch parts；Two notch part is from round platform
To big end extension at sleeve cone angle, through whole round platform sleeve；Described inner support core rod one end is round platform supporting part, and the other end is circle
Post connecting portion, the outer surface of the cylinder connecting portion are provided with the screw thread to match with handle inner thread, wherein round platform supporting part
The diameter of small end is less than the maximum gauge of sleeve round platform, and the maximum gauge at the big end of round platform supporting part is more than the maximum of sleeve round platform directly
Footpath.
Preferably, the handle is Anti-slip handle.
Preferably, the big end of the inner support core rod round platform supporting part is provided with an outstanding circular fin.
A kind of annular groove mill described in the utility model, product inner ring is socketed on annulus fin, by adjusting inner support
The openings of sizes of the relative position regulating sleeve of core rod and sleeve, makes annulus fin match with product inner ring, by rotating hand
Handle realizes the polishing to product inner ring, and the utility model is simple in construction, practical, can industrialized production.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1- sleeves；2- inner support core rods；3- notch parts；4- handles；5- annulus fins；6- circular fins.
Embodiment
Embodiment 1.
A kind of annular groove mill described in the utility model, including sleeve 1 and inner support core rod 2, the sleeve 1 are round platform sleeve
1, its inner hollow, the big end of the round platform sleeve 1 is provided with an outstanding annulus fin 5, the surface light of annulus fin 5
Sliding, its small end is fixed with a hollow handle 4, and the inwall of handle 4 is provided with internal thread；On the round platform sleeve 1 symmetrically
Provided with a pair of notch parts 3, plane where big end is averagely divided into two symmetrical sectors by two notch parts 3；Described two lack
Oral area 3 extends from the cone angle of round platform sleeve 1 to big end, through whole round platform sleeve 1；Described one end of inner support core rod 2 is round platform
Supporting part, the other end are cylinder connecting portion, and the outer surface of the cylinder connecting portion is provided with the spiral shell to match with the inner thread of handle 4
Line, the wherein diameter of round platform supporting part small end are less than the maximum gauge of the round platform of sleeve 1, and the maximum gauge at the big end of round platform supporting part is big
In the maximum gauge of the round platform of sleeve 1.Handle 4 described in the present embodiment is Anti-slip handle 4.
In use, sleeve 1 and inner support core rod 2 are disassembled, the annulus fin 5 of sleeve 1 is socketed in the inner groove of product
Inner support core rod 2, is then connected, is supportted round platform sleeve 1 using the round platform supporting part of inner support core rod 2 by place by screw thread with sleeve 1
Open, annulus fin 5 is tightly connected in the inner groove of product, the inner groove of product is polished by rotational handle 4.
Because the utility model is symmetrically provided with a pair of notch parts 3 on round platform sleeve 1, therefore, inner support core rod 2 just can be by round platform sleeve
1 support is big, makes the inner groove of the matching product of annulus fin 5 of sleeve 1.
Embodiment 2.
The present embodiment is substantially the same manner as Example 1, and difference is the round platform supporting part of inner support core rod 2 described in the present embodiment
Big end be provided with an outstanding circular fin 6, circular fin 6 can be used as handle 4, for adjusting inner support core rod 2 and sleeve 1
Between connection.
