Description
Technical field
The utility model relates to machine industry field, it is mainly used for accurately sharpening spiral bit, specifically one
Kind twist drill bit sharpening device.
Background technique
The apex angle of fluted drill is generally 118 °~120 °, and chisel edge angle is generally 55 °, when sharpening spiral bit, generally
It is hand-held spiral bit hand grinding on grinding wheel, the angle of fluted drill is completed mainly by range estimation, and when sharpening is easy to appear fiber crops
Flower point angle it is incorrect, apex angle is asymmetric, apex angle is symmetrical but cutting edge length is unequal, apex angle is asymmetric and cutting edge length not
Phenomena such as equal, not only make workpiece processing quality it is difficult to ensure that, and waste material, the waste sharpening time, reduce fluted drill
Service life, and it is also very high to the technical requirements of worker, working efficiency is greatly reduced, making part, increased production cost.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies of the prior art and provide twist drill bit sharpening device,
The technical scheme adopted by the utility model to solve the technical problem is as follows: the structure of the utility model include hexagonal prism seat, gland,
Housing screw, ring washer, fastening screw, spiral bit, it is characterised in that the center of hexagonal prism seat is provided with one 60 °
V-shaped groove, spiral bit are mounted in the V-shaped groove of hexagonal prism seat, and V-shaped groove can have a correctly positioning, pressure convenient for spiral bit
It covers and is provided with a through slot, be drilled with two through hole at left and right sides of gland, gland is installed to by hexagonal prism seat by fastening screw
On, the center of gland is provided with a tapped through hole, and the tapped through hole and housing screw cooperate, and housing screw withstands planchet
Piece is pressed on spiral bit in V-shaped groove.
The hexagonal prism seat is positive hexagonal prism, and two sides angle is 120 °, equal to the angle of spiral bit apex angle.
Assembling process: gland is tightened on hexagonal prism seat by two fastening screws, then housing screw is screwed to gland
It is a little in interior threaded hole, then spiral bit is put into the V-shaped groove of hexagonal prism seat, and two cutting edge of spiral bit is made to keep water
Level state is put into ring washer to suitable position, finally tightens housing screw, so that housing screw is pushed down ring washer and compresses fried dough twist again
Drill bit, the present apparatus install.
The utility model has the beneficial effects that structure is simple, it is easy to operate convenient for manufacture, securely and reliably；To worker's technology
Level requirement is low；Sharpening speed is fast, precision is high, improves working efficiency；Guarantee processing quality, extends spiral bit service life.
The present apparatus can sharpen various sizes of spiral bit in a certain range.
Detailed description of the invention
Fig. 1: the utility model embodiment schematic cross-sectional view.
Fig. 2: the utility model embodiment structural schematic diagram.
In figure: hexagonal prism seat 1, gland 2, housing screw 3, ring washer 4, fastening screw 5, spiral bit 6.
Specific embodiment
It is described with reference to make the utility model detailed description in detail below.As shown in the picture, the utility model
Structure includes hexagonal prism seat 1, gland 2, housing screw 3, ring washer 4, fastening screw 5, spiral bit 6, it is characterised in that six ribs
The center of housing 1 is provided with one 60 ° of V-shaped groove, and spiral bit 6 is mounted in the V-shaped groove of hexagonal prism seat 1, and V-shaped groove is just
There can be a correctly positioning in spiral bit 6, be provided with a through slot on gland 2, it is logical that the left and right sides of gland 2 is drilled with two
Gland 2 is installed on hexagonal prism seat 1 by hole by fastening screw 5, and the center of gland 2 is provided with a tapped through hole, should
Tapped through hole and housing screw 3 cooperate, and housing screw 3 withstands ring washer 4, spiral bit 6 is pressed in V-shaped groove.
The hexagonal prism seat 1 is positive hexagonal prism, and two sides angle is 120 °, equal to the angle of 6 apex angle of spiral bit.
Assembling process: gland 2 is tightened on hexagonal prism seat 1 by two fastening screws 5, then housing screw 3 is screwed to
It is a little in threaded hole in gland 2, then spiral bit 6 is put into the V-shaped groove of hexagonal prism seat 1, and make 6 liang of spiral bit cuttings
Sword keeps horizontality, is put into ring washer 4 to suitable position, finally tightens housing screw 3, housing screw 3 is made to push down planchet
Piece 4 compresses spiral bit 6 again, and the present apparatus installs.
Working principle: spiral bit 6 is mounted in the V-shaped groove of hexagonal prism seat 1, pays attention to two cutting edges one of spiral bit 6
Surely it to be horizontally arranged, V-shaped groove 0.5mm or so is slightly protruded in 6 front of spiral bit, and housing screw 3 compresses fluted drill by ring washer 4
First 6, it then holds fluted drill sharpener and sharpens drill bit front on grinding wheel, when cutting edge is flushed with the two sides of hexagonal prism,
Spiral bit 6 is unloaded, sharpening finishes.The present apparatus can sharpen various sizes of spiral bit in a certain range.
Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this
Novel conception and scope is defined, without departing from the design concept of the present utility model, ordinary skill in this field
The all variations and modifications that technical staff makes the technical solution of the utility model should all fall into the protection model of the utility model
It encloses, technical content requested for protection of the utility model is all described in the claims.
