Abstract
The invention discloses a novel glass drill, which consists of a drill bit, a drill handle and a drill body sequentially connected, and has the innovation that the large-diameter end of the drill body is connected with the drill handle, and the drill handle and the drill body are connected by welding; the small-diameter end of the drill body is connected with the drill bit, and the drill body and the drill bit are integrally formed. According to the glass drill provided by the invention, the cylindrical drill handle with positioning grooves is combined with the truncated cone-shaped drill body, so that the purposes of remitting impact force of press during processing, avoiding damage of glass, and effectively fastening the drill bit are achieved.
Description
Technical field
The invention belongs to glass processing instrument, particularly relate 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.
Summary of the invention
It is excessive that the technical problem to be solved in the present invention presses down impulsive force when being glass drilling, easily causes the fragmentation of glass.
For solving the problem, the invention 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.
Beneficial effect of the present invention is as follows:
1, the cylinder drillstock with detent combines with Rotary-table drill body by Glass drill head of the present invention, 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 invention, 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 invention, 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 invention.
Detailed description of the invention
Drawing reference numeral: 1, circumference bite, 2, apex point, 3, drill body, 4, drillstock, 5, positioning groove
For making goal of the invention of the present invention, technical scheme and advantage clearly, below in conjunction with accompanying drawing, embodiments of the present invention are described in further detail.
As shown in Figure 1, a kind of novel glass drill bit, is 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 structure of Glass drill head of the present invention, and 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 invention; it is not the restriction to technical solution of the present invention; 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 patent of the present invention.
