Abstract
The utility model discloses a novel medical step drill bit, by drill tip, brill body and drillstock triplex, its characterized in that: it personally experiences sth. Part of the body for step cylinder to bore the structure of body, it is connected with the drillstock to bore the one end that the diameter is big of body, the connected mode of boring body and drillstock is integrated forming, it is connected with the drill tip to bore the one end that the diameter is little of body, drill tip and brill body integrated forming, the drillstock is close to terminal position and has seted up the location slot. The utility model discloses a medical step drill bit has adopted the brill body of step cylinder body structure to combine together with the location slot, in medical drilling process, can realize that one bores porous beneficial effect.
Description
Technical field
This utility model belongs to Medical bit field, particularly relates to a kind of new medical Step drill.
Background technology
Drill bit is a kind of rotation and head end has the instrument of cutting power, general with carbon steel SK, or high-speed steel SKH2, the materials such as SKH3 through milling or rolling again through quenching, grind after tempering heat treatment and form, Drilling operation on metal or other materials, its scope of application is extremely wide, can apply to the toolroom machines such as drilling machine, lathe, milling machine, electric hand drill use.
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.Work process 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.
Drill bit obtains at mechanical field and uses widely, in the last few years, flourish along with medical and beauty treatment cause, drill bit have also been obtained at medical field and uses widely, but because the structure of structoure of the human body and machinery differs greatly, general drill bit well cannot use at medical field.
Utility model content
The technical problems to be solved in the utility model is that drill bit is for time medical, and a drill bit can only drill through the hole in same aperture, and Medical bit is too dull.
For solving the problem, this utility model provides following technical scheme: a kind of new medical Step drill, be made up of apex point, drill body body and drillstock three part, it is characterized in that: the structure of described drill body body is stepped cylindrical body, one end that the diameter of described drill body body is large is connected with drillstock, the connected mode of described drill body body and drillstock is monolithic molding, one end that the diameter of described drill body body is little is connected with apex point, described apex point and drill body intrinsic single are shaped, and described drillstock offers positioning groove near terminal position.
Further, the structure of described drill body body is stepped cylindrical body structure, and the front end of described stepped cylindrical body drill body body is 2:3:5 to end diameter ratio.
Further, the structure of described apex point is the cone that there is helical structure on surface, and the tapering of cone is 15 ~ 30 °, and the cone of cone is high is 3 ~ 5mm, and spacing between described spiral is 0.2 ~ 0.4mm.
Further, the structure of described detent is at cylinder drillstock end position rearward, offer a cylinder detent, the height of described cylinder detent is consistent with the diameter of described cylinder drillstock, and the diameter of described cylinder detent is 2 ~ 3mm.
The beneficial effects of the utility model are as follows:
1, medical Step drill of the present utility model have employed the drill body body of stepped cylindrical body structure and positioning groove combines, and in medical boring procedure, can realize the beneficial effect of a brill porous;
2, apex point of the present utility model is the conical structure that there is helical structure on surface, the tapering of cone is 15 ~ 30 °, the cone of cone is high is 3 ~ 5mm, spacing between described spiral is 0.2 ~ 0.4mm, specific spiral spaces and the tapering of cone, increases the borehole strength of drill bit, simultaneously row cut also convenient;
3, cylinder drillstock of the present utility model offers positioning groove, is easy to the installation of machine, also fasten installation simultaneously, play the effect of slip-off preventing.
Accompanying drawing explanation
If Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Drawing reference numeral: 1, apex point, 2, drill body body, 3, positioning groove, 4, drillstock
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 medical Step drill of the present utility model as shown in Figure 1, a kind of new medical Step drill, be made up of apex point 1, drill body body 2 and drillstock 4 three part, it is characterized in that: the structure of drill body body 2 is stepped cylindrical body, one end that the diameter of drill body body 2 is large is connected with drillstock 4, drill body body 2 is monolithic molding with the connected mode of drillstock 4, one end that the diameter of drill body body 2 is little is connected with apex point 1, apex point 1 and drill body body 2 monolithic molding, drillstock 4 offers positioning groove 3 near terminal position.The structure of drill body body 2 is stepped cylindrical body structure, and the front end of stepped cylindrical body drill body body 2 is 2:3:5 to end diameter ratio.The structure of apex point 1 is the cone that there is helical structure on surface, and the tapering of cone is 15 ~ 30 °, and the cone of cone is high is 3 ~ 5mm, spacing between spiral is 0.2 ~ 0.4mm, specific spiral spaces and the tapering of cone, increases the borehole strength of drill bit, simultaneously row cut also convenient.
The structure of detent 3 is at cylinder drillstock 4 end position rearward, offer a cylinder detent 3, the height of cylinder detent 3 is consistent with the diameter of cylinder drillstock 4, the diameter of cylinder detent 3 is 2 ~ 3mm, be easy to the installation of machine, also fasten installation simultaneously, play the effect of slip-off preventing.
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 this utility model patent.
