It is more demanding to grinding personnel specialty technical merit in journey, not only drill bit is lost when layman's grinding drill it is larger, and
And can not ensure angle problem after grinding, drill bit is not sharp after grinding, and fluted drill grinding fixture can solve this well
Class problem.
Utility model content
The purpose of this utility model is to need to be ground after being passivated in the process for the use of fried dough twist drill bit, it is proposed that Yi Zhongke
With fast assembling-disassembling and the fluted drill grinding attachment of angle of drill bit after drill bit grinding is can guarantee, to solve drill bit using being needed after passivation
The problem of professional is ground drill bit, ensure stock removal when fluted drill grinding and angle value after grinding, and
It is easy to operate, work well, be easy to disassemble, the grinding efficiency and ground effect of fried dough twist drill bit can be greatly improved.
To achieve the above object, the utility model provides a kind of fluted drill grinding attachment, the fluted drill grinding attachment
Including grinding fixture bottom plate that shape is regular hexagonal prism shape, the grinding fixture latch that is arranged on the grinding fixture bottom plate with
And the drill bit tie down screw being arranged on the grinding fixture latch is extended vertically through, pair of the grinding fixture plate upper surface
Diagonal position is equipped with the triangular groove that angle is 90 °, and the center of the grinding fixture latch is equipped with threaded hole, the drill bit
Fried dough twist drill bit is held out against by threaded hole and is fixed in the triangular groove by tie down screw.
Preferably, the grinding fixture latch is circular plate with holes.
Based on the above-mentioned technical proposal, the utility model has the advantages that：
The fluted drill grinding attachment of the utility model is proposed for needing to be ground after being passivated during the use of fried dough twist drill bit
One kind with fast assembling-disassembling and can guarantee angle of drill bit after drill bit grinding, can not only be solved using the present apparatus drill bit use it is blunt
The problem of needing professional to be ground drill bit after change, and it is easy to operate, work well, be easy to disassemble, can be significantly
Improve the grinding efficiency and ground effect of fried dough twist drill bit.
In use, fried dough twist drill bit is put into fluted drill grinding fixture bottom plate triangular slot, the fluted drill being ground is needed to bore
Head process goes out bottom plate hexagonal angle a little, tightens fried dough twist drill bit tie down screw, compresses the fried dough twist drill bit for needing grinding, will be numb
Two faces that flower bores 120 ° of grinding fixture are close to abrasive grinding wheel respectively, are ground fried dough twist drill bit, which compresses reliable, Er Qiecao
Make simply to substantially increase the efficiency that 120 ° of fluted drill drill bits are ground, there is extraordinary practicability.
Description of the drawings
Attached drawing described herein is used to provide a further understanding of the present invention, and is constituted part of this application,
The exemplary embodiment of the utility model and the description thereof are used to explain the utility model, does not constitute to the improper of the utility model
It limits.In the accompanying drawings：
Fig. 1 is fluted drill grinding attachment structural schematic diagram；
Fig. 2 is fluted drill grinding attachment schematic side view；
Fig. 3 is fluted drill grinding attachment schematic top plan view.
Specific implementation mode
Below by drawings and examples, the technical solution of the utility model is described in further detail.
The utility model provides a kind of fluted drill grinding attachment, and the present apparatus includes fluted drill grinding fixture bottom plate, fried dough twist
Grinding fixture latch, fried dough twist drill bit, four part of fried dough twist drill bit tie down screw composition are bored, as shown in FIG. 1 to 3, wherein
Show a kind of preferred embodiment of the utility model.
As shown in Figure 1 and Figure 2, the fluted drill grinding attachment include shape be regular hexagonal prism shape grinding fixture bottom plate 1,
Grinding fixture latch 2 on the grinding fixture bottom plate 1 is set and extends vertically through setting and is locked in the grinding fixture
The diagonal positions of drill bit tie down screw 4 on plate 2,1 upper surface of grinding fixture bottom plate are equipped with the triangle that angle is 90 °
Slot, the center of the grinding fixture latch 2 are equipped with threaded hole, and the drill bit tie down screw 4 is by threaded hole by fried dough twist
Drill bit 3, which is held out against, to be fixed in the triangular groove.
As shown in figure 3, the grinding fixture bottom plate 1 is hexagon, interior angle is 120 °, conforms exactly to the grinding of fluted drill drill bit
Angle afterwards, diagonal positions are provided with the triangular groove that angle is 90 ° on hexagon bottom plate, for placing the fried dough twist for needing grinding
Drill bit 3.Preferably, the grinding fixture latch 2 is circular plate with holes, and plectane center is provided with threaded hole, for being screwed into drill bit
Tie down screw 4.The drill bit tie down screw 4 needs the fried dough twist drill bit 3 of grinding for being locked.
The fluted drill grinding attachment of the utility model is proposed for needing to be ground after being passivated during the use of fried dough twist drill bit
One kind with fast assembling-disassembling and can guarantee angle of drill bit after drill bit grinding, can not only be solved using the present apparatus drill bit use it is blunt
