Abstract
The utility model relates to a standard detecting template for sharpening angles of an electric knife sharpener, which belongs to an attachment of an electric power abrasive product. The utility model forms a plate shape with four angles, and concave slots are respectively arranged between the angle 1 and the angle 2, the angle 2 and the angle 3, and the angle 3 and the 4 angle. When the angle 1 and the angle 2 are crossed over a circular arc, the radius of which is R, an included angle between the edge of the angle 1 and the circular arc is 30 DEG, and an included angle between the edge of the angle 2 and the circular arc is 25 DEG. When the angle 2 and the angle 3 are crossed over a circular arc, the radius of which is R, an included angle between the edge of the angle 2 and the circular arc is 60 DEG, and an included angle between the edge of the angle 3 and the circular arc is 20 DEG. When the angle 3 and the angle 4 are crossed over a circular arc, the radius of which is R, an included angle between the edge of the angle 3 and the circular arc is 40 DEG, and an included angle between the edge of the angle 4 and the circular arc is 25 DEG. A corresponding angle is marked near the edge of each angle, and the utility model is also marked with various general tool bits and corresponding best sharpening angles. The utility model has the advantages of low price, easy use and accurate detection, and can be widely used in sharpening various tool bits.
Description
Technical field
The utility model belongs to electronic grinding tool technical field, more particularly relates to the design of the sharpening angle standard detection template of electric knife sharpener.
Background technology
Traditional electric knife sharpener is electric grinder.Existing electric grinder does not all have special-purpose sharpening angle standard detection template, can't in time detect sharpening angle.Some operating personnel have to use general bevel protractor to detect.General bevel protractor price is more expensive, needs during use to adjust, and operation also bothers.Therefore, many people can only grasp the angle of grinding with eye estimate.The angular error that human eye is estimated is very big, can not guarantee the angle and the quality of tool sharpening.
The best sharpening angle of cutter commonly used is fixed in fact.As carpenter's plane and carpenter's flat chisel is 30 ° or 20 °, and scissors is 60 °, and table knife is 20 °, and fruit knife is 40 ° or the like.This just provides possibility for making special-purpose standard detection template.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, and a kind of best sharpening angle that is manufactured with multiple cutter commonly used is provided, and is cheap, easy to use, detects the sharpening angle standard detection template of electric knife sharpener accurately.
In order to achieve the above object, the utility model is tabular, has four angles.Respectively have recessed groove between its 1 jiao and 2 jiaos, 2 jiaos and 3 jiaos, 3 jiaos and 4 jiaos, have only intersecting of corresponding two angles when detecting with circular arc with assurance.When straddling on the circular arc that radius is R with 1 jiao and 2 jiaos, 1 jiao the limit and the angle of circular arc are 30 °, and 2 jiaos the limit and the angle of circular arc are 25 °.When straddling on the circular arc that radius is R with 2 jiaos and 3 jiaos, 2 jiaos the limit and the angle of circular arc are 60 °, and 3 jiaos the limit and the angle of circular arc are 20 °.When straddling on the circular arc that radius is R with 3 jiaos and 4 jiaos, 3 jiaos the limit and the angle of circular arc are 40 °, and 4 jiaos the limit and the angle of circular arc are 25 °.Near the mark on the limit at each angle has corresponding angle, for the detection of angle provides convenience.
During work, select best sharpening angle according to the cutter of desiring sharpening earlier, find corresponding angle; Then corresponding two angles of the present utility model are straddled on the abrasive wheel grinding wheel arc that radius is R, the cutter of sharpening is inserted in the angle of the limit that leans against respective corners and abrasive wheel grinding wheel arc, whether identically see.As inequality, then grinding should be added again, till identical.
Also mark above the template several cutters commonly used and corresponding best sharpening angle thereof are arranged.Be convenient to the user and contrast use at any time.
Also have the aperture of being convenient to deposit usefulness on the template.Aperture can be used for the utility model is inserted into the somewhere, or passes with steel wire or line etc. and to deposit.
Task of the present utility model comes to this and finishes.
The utility model provides a kind of best sharpening angle that is manufactured with multiple cutter commonly used, and is cheap, easy to use, detects the sharpening angle standard detection template of electric knife sharpener accurately.It can be widely used in the sharpening of various cutters.
Description of drawings
Fig. 1 is structure of the present utility model and user mode figure thereof.
Embodiment
Embodiment 1.A kind of sharpening angle standard detection template of electric knife sharpener, as shown in Figure 1.It is tabular 5, has four angles 1～4.Respectively have recessed groove 6 between its 1 jiao and 2 jiaos, 2 jiaos and 3 jiaos, 3 jiaos and 4 jiaos, have only circular arc 8 corresponding two angles and emery wheel 7 to intersect when detecting with assurance.In the time of when straddle the circular arc 8 of emery wheel 7 that radius is R with 1 jiao and 2 jiaos on, the angle 9 of 1 jiao limit and circular arc 8 is 30 °, and the angle 10 of 2 jiaos limit and circular arc 8 is 25 °.When straddling on the circular arc 8 that radius is R with 2 jiaos and 3 jiaos, the angle of 2 jiaos limit and circular arc 8 is 60 °, and the angle of 3 jiaos limit and circular arc 8 is 20 °.When straddling on the circular arc 8 that radius is R with 3 jiaos and 4 jiaos, the angle of 3 jiaos limit and circular arc 8 is 40 °, and the angle of 4 jiaos limit and circular arc 8 is 25 °.Near the mark on the limit at each angle has corresponding angle several 11, for the detection of angle provides convenience.Also mark above the embodiment 1 several cutters commonly used and corresponding best sharpening angle 12 thereof are arranged.Be convenient to the user and contrast use at any time.
It also has the aperture 13 of being convenient to deposit usefulness.Aperture 13 can be used for the utility model is inserted into the somewhere, or passes with steel wire or line etc. and to deposit.
14 for desiring the cutter of grinding among Fig. 1, and 15 is the anchor clamps that this cutter 14 of clamping is convenient to the electric knife sharpener of grinding.
