Abstract
The utility model relates to a tool of grinding a drill bit in the machine building, particularly to a tool setting gage for grinding a standard spiral bit with a taper shank, which comprises a chassis, a pillar which is vertically fixed with the chassis, a support piece which can slide along the pillar and a lock bolt which can fix the support piece and the pillar, wherein a tool setting gauge is fixed on the chassis and is provided with a V-shaped slot with the angle of 180 DEG, and the symmetrical center line of the V-shaped slot is parallel to the center line of the pillar. A guiding key used for the slide of the support piece is arranged on the pillar, the lower part of the support piece is fixed with a core clamper, and the perpendicular of the core clamper and the symmetrical center line of the V-shaped slot are concentric. The tool setting gauge is applicable to standard spiral bit with a taper shank with different diameters. Compared with the traditional grinding by hand, the tool setting gauge of the utility model can save the grinding time, reduce the technical requirement to the operator and raise the grinding quality of the drill bit.
Description
Technical field:
The utility model relates to the instrument of sharpening drill bit in the machinery manufacturing industry, specifically a kind of grinding taper shank standard spiral bit tool setting gauge.
Background technology:
At present in machinery manufacturing industry, except that the used standard spiral bit of Digit Control Machine Tool on cutter and tool grinding machine the sharpening, used standard spiral bits such as most machine tools such as lathe, drilling machine, milling machine all are by manual sharpening.Grinding standard spiral bit should guarantee 2 basic demands: one, the drill bit drift angle equals 118 °; Two, two main cutting edges and bit central symmetry.And hand grinding standard spiral bit by the experience grinding, is observed by eyes, is difficult to guarantee above-mentioned two electric requirements.First requirement can not guarantee, can influence the cutting ability and the chip removal of drill bit; Second requirement can not guarantee, what can cause that a main cutting cuts is dark, and that another main cutting is cut is shallow, even can produce the single-blade cutting.Will make the hole of being bored depart from desired center line like this, perhaps big hole drill, also can reduce stock-removing efficiency simultaneously.
Summary of the invention:
Goal of the invention of the present utility model is intended to solve two problems that present hand grinding standard spiral bit can not guarantee the sharpening requirement, and provide a kind of grinding taper shank standard spiral bit tool setting gauge, when grinding taper shank standard spiral bit, utilize this tool setting gauge, the drill bit drift angle that can guarantee the standard spiral bit of grinding equals 118 °, and two main cutting edges and bit central symmetry.
The technical scheme that realizes the foregoing invention purpose is: this grinding taper shank standard spiral bit with tool setting gauge comprise the chassis, with the column of this chassis vertical fixing, the rest pad that can slide along this column, the clamping screw that this rest pad and column can be fixed, be fixed with bit ga(u)ge on this chassis, have a V-type groove that is 118 ° of angles on this model, the symmetrical center line of this V-type groove is parallel with the center line of this column; This column is provided with the feather key that slides for this rest pad, and this rest pad bottom is fixed with top, and this top vertical line is concentric with the symmetrical center line of this V-type groove.
According to described this grinding taper shank standard spiral bit tool setting gauge of this case, applicable to the standard taper-shank twist drill of different-diameter.Compare with traditional free-hand sharpening, use this tool setting gauge, can save the grinding time, reduced specification requirement, improved the grinding quality of drill bit the operator.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Provide a specific embodiment of the present utility model below in conjunction with accompanying drawing.
This grinding taper shank standard spiral bit that present embodiment provides is made up of chassis 1, bit ga(u)ge 2, column 3, top 4, rest pad 5, clamping screw 6, feather key 7, bolt 8, V-type groove 9 with tool setting gauge, these column 3 vertical fixing are on chassis 1, this rest pad 5 is slidingly mounted on the column 3, and it is provided with the clamping screw 6 that itself and column 3 are fixed; Be fixed with bit ga(u)ge 2 on this chassis 1, have a V-type groove 9 that is 118 ° of angles on this model 2, the symmetrical center line of this V-type groove 9 is parallel with the center line of this column 3; This column 3 is provided with the feather key 7 that slides for this rest pad 5, and it is top 4 that these rest pad 5 bottoms are fixed with, and this vertical line of top 4 is concentric with the symmetrical centre of this V-type groove 9.
This grinding taper shank standard spiral bit with the tool setting gauge using method is:
At first, taper shank standard spiral bit is placed on 9 li of the V-type grooves of bit ga(u)ge 2, position line in two main cutting edges and the V-type groove 9 is overlapped, with top 4 centre bores that withstand the drill bit afterbody, observe the identical situation of two main cutting edges and V-type groove 9 groove faces of drill bit then in the horizontal direction with eyes.Contact with a face of V-type groove 9 if see a main cutting edge, illustrate that two main cutting edges of drill bit are asymmetric, should grind off that main cutting edge that contacts with V-type groove 9 again, till two main cutting edges all contact.If two main cutting edges all are that the outer end cutting edge contacts with V-type groove 9, illustrate that the drill bit drift angle is excessive, then should grind off the part on two outer limits of main cutting edge of drill bit, fit like a glove up to two main cutting edges and V-type groove 9.
Claims (1)
1, a kind of grinding taper shank standard spiral bit tool setting gauge, comprise the chassis, with the column of this chassis vertical fixing, the rest pad that can slide along this column, the clamping screw that this rest pad and column can be fixed, it is characterized in that being fixed with bit ga(u)ge on this chassis, have a V-type groove that is 118 ° of angles on this model, the symmetrical center line of this V-type groove is parallel with the center line of this column; This column is provided with the feather key that slides for this rest pad, and this rest pad bottom is fixed with top, and this top vertical line is concentric with the symmetrical centre of this V-type groove.
