Abstract
The utility model discloses a kind of novel reamer, part connect with director element and is fixed by screw on cutter hub, leaf spring is equipped on the outside of screw, part is connect with wedge type block under cutter hub, wedge type block connect with blade and is fixed by screw, the utility model leads to director element can swing around the center of curvature of itself, it is adjacent to the working portion of reamer always with workpiece machined surface along overall length, reach self-aligning action, to, it ensure that point contact stress reduces before guide part, is improved processing quality and tool life all.
Description
Technical field
The utility model relates to a kind of novel reamers, belong to the technical field of reamer.
Background technique
The prismatic targeting part of Single-blade reamer is normally fixed to motionless in cutter hub slot.The shortcomings that this structure is to be oriented to
The machined surface of part and hole cannot be adjacent to completely, and it is uneven along the abrasion of people's degree direction to be directed at reamer working portion, therefore reduces
Durability, meanwhile, it is inconvenient to replace after structural wear.
Summary of the invention
Purpose of utility model: above-mentioned in order to overcome the problems, such as, the utility model provides a kind of novel reamer.
Process program: the utility model discloses a kind of novel reamer, including blade, screw, wedge type block, cutter hub, leaf spring, leads
To element, part connect with director element and is fixed by screw on the cutter hub, and leaf spring, the cutter hub are equipped on the outside of the screw
Lower part is connect with wedge type block, and the wedge type block connect with blade and fixed by screw.
Further, the director element outer shape is in semicircle key-like.
The utility model has the advantage that
Logical director element can be swung around the center of curvature of itself, make the working portion of reamer along overall length always with workpiece quilt
Machined surface is adjacent to, and reaches self-aligning action, to ensure that point contact stress reduces before guide part, keeps processing quality and cutter resistance to
Expenditure is all improved.
Detailed description of the invention
A kind of Fig. 1: structural schematic diagram of novel reamer of the present embodiment.
In figure: blade 1, screw 2, wedge type block 3, cutter hub 4, leaf spring 6, director element 7.
Specific embodiment
The utility model is further elaborated below in conjunction with attached drawing and by specific embodiment, it should be pointed out that: for this
For the common process personnel of technology field, without departing from the principle of this utility model, to the various of the utility model
The modification of equivalent form falls within the application range as defined in the appended claims.
Embodiment 1:
As Fig. 1 institute the utility model discloses a kind of novel reamer, including blade 1, screw 2, wedge type block 3, cutter hub 4, leaf spring
6, director element 7, part connect with director element 7 and is fixed by screw 2 on the cutter hub 4,7 outer shape of director element
In semicircle key-like, leaf spring 6 is equipped on the outside of the screw 2, the lower part of the cutter hub 4 connect with wedge type block 3, the wedge type block 3 and
Blade 1 is connected and is fixed by screw 2.
Working principle: blade 1 is fixed in a slot of cutter hub 4 with wedge block 3, screw 2, other two slots of cutter hub
Equipped with director element 7, the shape of director element 7 is similar to woodruff key, in order to improve wearability, the hard coated layer on its working face
Director element and cutter hub non-working surface are compressed, then leaf spring are tightened with screw by matter alloy, leaf spring 6.
The utility model has the advantage that
Logical director element can be swung around the center of curvature of itself, make the working portion of reamer along overall length always with workpiece quilt
Machined surface is adjacent to, and reaches self-aligning action, to ensure that point contact stress reduces before guide part, keeps processing quality and cutter resistance to
Expenditure is all improved.
