Abstract
The utility model relates to a quick assembled drilling bit, which comprises a drill body (1) and a coaxial drill shank (2) connected with the drill body. The utility model is characterized in that the drill shank forms a hexagon prism shape, and the cross section is a regular hexagon. The drill shank can be also provided with a ring groove according to actual demand. The utility model doesn't need any auxiliary tool when the utility model is used for assembling and disassembling a chuck of a machine tool or an electric tool, and once assembly or disassembly only requires several seconds. The efficiency is improved by several times to tens of times, and the disadvantages brought by clamp abrasion are thoroughly avoided. When the utility model is used, the required torque is not influenced by the friction at all, and thus, the utility model fundamentally solves the problem of skid of a connecting rod and reduces the use cost simultaneously.
Description
The utility model relates to a kind of drill bit that adopts mechanical means that object is carried out drilling processing, particularly a kind of ready-package drill bit.
Drill bit generally is made of drill body and drillstock two parts, and drillstock partly is held on the chuck of lathe or electric tool during use, drives the drill body rotation and work when the output shaft of lathe or electric tool rotates.The drillstock part generally all cylindrical (as shown in Figure 6) of existing drill bit, therefore required in use moment of torsion provides by the frictional force between it and the chuck fully, can cause frictional force to descend when various reasons (having greasy dirt, chuck wearing and tearing etc. to occur) occurring as drillstock and chuck faying face, the phenomenon that drillstock skids on chuck appears, influence is normal to be used, even under regular service conditions, also usually the situation that drillstock skids can occur, this brings great inconvenience to use, also makes its use occasion be subjected to great restriction; In addition when drill bit is installed and removed on the chuck of electric tool, must use the special carrier spanner could clamp its drillstock, and in use for some time, when the engagement position of chuck and its special spanner can wear phenomenon occur, more make mounting or dismounting seem very inconvenient, therefore when reality is used, more time and efforts flower is arranged in the mounting or dismounting action.
The purpose of this utility model just is to provide at above-mentioned prior art present situation the ready-package drill bit on a kind of chuck that can apace drill bit be installed on lathe or electric tool.
The purpose of this utility model is achieved in that the drill body part-structure that does not change existing drill bit, only the drillstock partial design is become the hexagonal cylindricality, and its cross section is a regular hexagon.
For cooperating a kind of quick-changing type special carrier that has now occurred, can be provided with a cannelure at the corresponding position of described drillstock part, when being sub-packed on the chuck with the drill shank of convenient drill bit, one resilient clip of chuck can fall into this cannelure, thereby drill bit is fixed, be unlikely to come off from chuck.
Compared with prior art, the utility model when mounting or dismounting without any need for aid, mounting or dismounting once only need several seconds, efficient has improved several times to tens times, and thoroughly avoided the drawback brought because of clamp wear, required moment of torsion is not subjected to the influence of frictional force fully yet during use, has fundamentally solved the drillstock problem of slip, has reduced use cost simultaneously yet.
Description of drawings;
Fig. 1 is the structural representation of the utility model embodiment one (parallel shank twist drill).
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the structural representation of drillstock ringless-type groove (parallel shank twist drill).
Fig. 4 is the vertical view of Fig. 3.
Fig. 5 is applied to the embodiment of parallel shank percussion drill head for the utility model.
Fig. 6 is the structural representation of drill bit of the prior art.
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
Be the embodiment of a straight shank twist drill head as shown in Figure 1 and Figure 2, comprise drill body (1) and drillstock (2), drill body (1) planform is same as the prior art, and this does not give unnecessary details.The same drill body of drillstock (2) (1) is coaxial to link to each other, drillstock (2) is the hexagonal cylindricality, its cross section is a regular hexagon, drillstock (2) is provided with a cannelure (21), be used for mating a kind of novel quick-changing type special carrier now, when drill bit shank partly is loaded on the chuck, resilient clip on the chuck can fall into this cannelure, thereby drill bit is fixed, be unlikely to come off from chuck, therefore this drillstock can clamping again can clamping on the common chuck on the quick-changing type special carrier, the chamfering of drillstock (2) afterbody is mainly used to strengthen the practicality and the aesthetic property of drill bit.
In actual applications, also can be by instructions for use with the cancellation of the cannelure (21) on the drillstock (2), as shown in Figure 3.
The utility model only changes the planform of drillstock (2), and no matter what form drill body is, all can use; As be applied to parallel shank percussion drill head shown in Figure 5.
Claims (2)
1, a kind of ready-package drill bit comprises drill body (1) and the coaxial drillstock that links to each other (2) with it, it is characterized in that described drillstock (2) is the hexagonal cylindricality, and its cross section is a regular hexagon.
2, ready-package drill bit as claimed in claim 1 is characterized in that described drillstock (2) is provided with a cannelure (21).
