Description

The abrasive wheel structure

Technical field

The utility model is about a kind of abrasive wheel structure.

Background technology

" a workman wants to do his work well must first sharpen his tools ", carry out machining with sharp keen drill bit or milling cutter, not only time saving and energy saving, and be easier to control accuracy, even if but the sharpest keen drill bit or milling cutter, it is continuing still can to become pure gradually under the use, therefore must repair the blade of this drill bit or milling cutter with abrasive wheel, keeps best sharp keen state at any time in order to do keeping this drill bit or milling cutter.

Abrasive wheel is to rotate around the center for motor drives now, this abrasive wheel have one with the cutting end face of central vertical, the one cutting circle side face that equidistantly rotates around the center, the user visual oneself custom and in this cutting end face, the cutting circle side face carries out the blade finishing of drill bit or milling cutter, in general, bottom blade with this abrasive wheel bit dressing or milling cutter does not have too big difficulty, maximum difficulty is the circumference blade of bit dressing or milling cutter, because this circumference blade mostly is provided with along the helical form chip area, be formed with the radial relief angle between this circumference blade and chip area, the radial clearance angle, be with, this circumference blade of desire correction just must grind this angle of relief, the cutting end face of abrasive wheel now, angle between the cutting circle side face is to be 90 degree, be difficult to insert this angle of relief of finishing along chip area, cause the circumference blade effectively to repair smoothly, make drill bit or milling cutter can't keep best sharp keen state.

The utility model content

The purpose of this utility model provides the abrasive wheel structure of a kind of effectively bit dressing or milling cutter circumference blade, makes drill bit or milling cutter keep best sharp keen state.

For achieving the above object, solution of the present utility model is: a kind of abrasive wheel structure, and its abrasive wheel is made of fuse, first abrasive material and second abrasive material; Its fuse has a center of rotation and both ends of the surface, and first abrasive material is arranged at this fuse one end face, and this first abrasive material is formed with a cutting end face and a cutting periphery; Second abrasive material is located on the fuse periphery, and this second abrasive material has a cutting end face and a cutting taper seat, and forms an acute angle part less than 90 degree between the cutting end face and the cutting circle conical surface.

The cutting end face and the angle between the cutting circle side face of described first abrasive material are 90 degree.

The granularity of described second abrasive material is thick than first abrasive material.

Described fuse center provides the useful mesopore that rotates around the center for driving shaft drives.

Described fuse has the end face of two vertical centres, is concaved with a ring-type shoulder between one end and periphery, and first abrasive material is to be fixedly arranged in shoulder, and is formed with the cutting circle side face of a cutting end face that trims with the fuse end face, an outstanding shoulder periphery.

The cutting circle side face of described first abrasive material is concaved with in order to the breach in abutting connection with second abrasive material.

Described fuse periphery forms the taper seat of flaring by shoulder to the other end, and second abrasive material is the corresponding taper seat that is fixedly arranged in, and forms cutting end face, the cutting circle conical surface that can rotate around the center that trims with the fuse other end.

After adopting such scheme, this abrasive wheel is that the end face in fuse is provided with first abrasive material, and fuse is equipped with second abrasive material in addition, the angle of controlling then between first abrasive material cutting end face and cutting circle side face is 90 degree, so that the usefulness of finishing milling cutter or drill bit bottom blade to be provided respectively, then have the cutting end face and the cutting circle conical surface as for second abrasive material, and form an acute angle part less than 90 degree between the two sides, this sharp portion of separating can insert milling cutter or flute of drill and the relief of repairing the circumference blade is separated, and makes the utility model abrasive wheel have the convenience of comprehensive grinding milling cutter or drill bit according to this.

In addition, the granularity of this second abrasive material is thick than first abrasive material, makes its taper seat, acute angle part can repair bottom blade, angle of relief fast, and makes this angle of relief superficiality meet required.

The specific embodiment

See also Fig. 1 to Fig. 5, the utility model abrasive wheel is to comprise:

Fuse 10, please cooperate Fig. 5 to see it, it has a center of rotation, this center has provided mesopore 11, use for driving shaft drives and rotate around the center, fuse 10 has the

end face

12,13 of two vertical centres, is concaved with a ring-type shoulder 14 between one end 12 and periphery, and fuse 10 extra incomes are formed the taper seat 15 of flaring to other end 13 by shoulder 14;

First abrasive material 20, please cooperate Fig. 1 and Fig. 5 to see it, be to be fixedly arranged in shoulder 14, and be formed with the cutting circle side face 22 of a cutting end face that trims with fuse 10 end faces 12 21, outstanding shoulder 14 peripheries, the angle that these first abrasive material, 20 cutting end faces 21 and cutting circle side face are 22 is 90 degree, can look the usefulness that user's habit plane provides finishing milling cutter or drill bit bottom blade; And cutting circle side face 22 is concaved with a breach 23 in the position of relative fuse 10 other ends 13, in order to the second following abrasive material 30 of adjacency;

Second abrasive material 30, please cooperate Fig. 1 and Fig. 5 to see it, it is the corresponding taper seat 15 that is fixedly arranged in, and be formed with cutting end face 31, the cutting circle conical surface 32 that can rotate that trims with fuse 10 other ends 13 around the center, 32 of this cutting end face 31 and the cutting circle conical surfaces form an acute angle part 33 less than 90 degree, this acute angle part 33 can be inserted milling cutter or flute of drill and repair the angle of relief of circumference blade, makes the utility model abrasive wheel have the convenience of comprehensive grinding milling cutter or drill bit according to this.

In addition, the granularity of this second abrasive material 30 is the thick than first abrasive material 20 of control, make its cutting circle conical surface 32 that the usefulness of milling cutter or the blade rough lapping of drill bit bottom can be provided in advance, the cutting circle side face 22 of first abrasive material 20 then can form the usefulness of thin (essence) grinding; And this acute angle part 33 can be repaired angle of relief fast, makes this angle of relief grind numb superficiality and meets required.

In sum, overall structure of the present utility model is reformed all shortcoming commonly using structure fully, makes the acute angle part 33 of the utility model abrasive wheel can be really and repair the angle of relief of milling cutter or drill bit smoothly.

The above person of thought, only be of the present utility model one than preferred embodiment, when can not with qualification scope of the present utility model, promptly the equalization of being done according to the utility model claim generally changes and modifies, and all should still belong in the scope that the utility model contains.
