Abstract
The utility model discloses a novel glass drill bit is connected by drill tip, drillstock and brill body triplex and constitutes, and its innovation point lies in: it is connected with the drillstock to bore the big one end of body diameter, the drillstock is the welding formula with boring the body coupling mode, it is connected with the drill tip to bore the little one end of body diameter, it is integrated forming with the drill tip to bore the body. The utility model discloses a cylinder drillstock that the glass drill bit will have positioning groove combines together with the rotary -table brill body, has reached the impact force that pushes down when alleviating processing, avoids glass's damage to can the effectual mesh that fastens the drill bit.
Description
Technical field
The utility model belongs to glass processing instrument, particularly relates to a kind of novel glass drill bit.
Background technology
Drill bit, as the indispensable instrument of boring, is engineer's common tool; The form of drill bit is more, and purposes is comparatively wide, and the pass having boring is also more.Because boring is according to the requirement of pass, the requirement of sheet material, there is different drill bit design requirements.Various informative.At present, although market drill bit is more.
Drill bit goes out through hole or blind hole in order to drilling on solid material, and can to the cutter of existing hole reaming.Conventional drill bit mainly contains fluted drill, centre drill, chit drill, depth drill and cylindrical drill.Though reamer counterbit can not be holed on solid material, also they are included into drill bit one class traditionally.The course of work dig pit operation time, drill bit, with vertical shaft rotary, moves axially simultaneously.Soil is cut under the moment of torsion and responsive to axial force of drill bit, is raveled under the extruding and centrifugal action of working-blade, forms native stream and presses to hole wall, simultaneously along page elevator to earth's surface.When native stream moves to without hole wall stop place, because centrifugal action hack is thrown around hole, complete the process of digging pit.
Intensity due to glass is higher and fragile, in many occasions, glass needs boring, but the Glass drill head of prior art adopts horizontal line shape cutting edge, and the thin-walled of cutting edge side is provided with shallow trace parallel lines decorative pattern, these decorative patterns go out bits when being used for glass drilling, but its diamond on parallel decorative pattern does not in use play the effect of creeping into, and cause a large amount of waste to a certain extent, and it also can affect working (machining) efficiency, also easily cause workpiece to break, practicality is poor.
Utility model content
It is excessive that the technical problems to be solved in the utility model presses down impulsive force when being glass drilling, easily causes the fragmentation of glass.
For solving the problem, the utility model provides technical scheme: a kind of novel glass drill bit, by apex point, drillstock and drill body three part connect and compose, it is characterized in that: one end that described drill body diameter is large is connected with drillstock, described drillstock and drill body connected mode are welded type; One end that described drill body diameter is little is connected with apex point, and described drill body and apex point are monolithic molding.
Further, the structure of described apex point is cylinder, and described apex point leading section offers circumference bite, and the vertical angle of described circumference bite and apex point is 15 ~ 20 °.
Further, the structure of described drill body is Rotary-table, and the diameter up and down of described Rotary-table drill body is than being 1:3.
Further, the structure of described drillstock is slender cylinder, and length is 5 ~ 7cm, and diameter is 2 ~ 3cm, and the rearward end periphery along described cylinder drillstock offers 2 detents up and down, and the diameter of described detent is 1 ~ 2cm.
The beneficial effects of the utility model are as follows:
1, the cylinder drillstock with detent combines with Rotary-table drill body by Glass drill head of the present utility model, reaches the impulsive force that presses down when alleviating processing, avoids the damage of glass, and can the object of effective securing drill bits;
2, the apex point being provided with circumference bite of the present utility model, circumferential cutting edge and vertical line orientation angle are 15 ~ 20 °, be conducive to drill bit to contact with glassy phase and make, drill bit creep into operation, cutting edge has angle in the vertical direction, thus can avoid brokenly cutting the accumulation in discharge process, thus ensure that workpiece creep into operation;
3, cylinder drillstock of the present utility model, the rearward end periphery of cylinder drillstock offers 2 detents up and down, can play securing drill bits, prevents the self falling descending drill bit in working order, avoids unnecessary the scrapping of workpiece, reduces production cost.
Accompanying drawing explanation
If Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Drawing reference numeral: 1, circumference bite, 2, apex point, 3, drill body, 4, drillstock, 5, positioning groove
For making utility model object of the present utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
The structure of Glass drill head of the present utility model as shown in Figure 1, a kind of novel glass drill bit, connected and composed by apex point 2, drillstock 4 and drill body 3 three part, it is characterized in that: one end that drill body 3 diameter is large is connected with drillstock 4, drillstock 4 and drill body 3 connected mode are welded type; One end that drill body 3 diameter is little is connected with apex point 2, and drill body 3 and apex point 2 are monolithic molding.
The structure of apex point 2 is cylinder, apex point 2 leading section offers circumference bite 1, circumference bite 1 is 15 ~ 20 ° with the vertical angle of apex point 2, be conducive to drill bit to contact with glassy phase and make, drill bit creep into operation, cutting edge has angle in the vertical direction, thus can avoid brokenly cutting the accumulation in discharge process, thus ensure that workpiece creep into operation.
The structure of drill body 3 is Rotary-table, and the diameter up and down of Rotary-table drill body 3, than being 1:3, reaching the impulsive force pressed down when alleviating processing, avoids the damage of glass,
The structure of drillstock 4 is slender cylinder, length is 5 ~ 7cm, diameter is 2 ~ 3cm, rearward end periphery along cylinder drillstock 4 offers 2 detents 5 up and down, the diameter of detent 5 is 1 ~ 2cm, can play securing drill bits, prevents the self falling descending drill bit in working order, avoid unnecessary the scrapping of workpiece, reduce production cost.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of the utility model patent.
