Abstract
The invention relates to a machining tool, in particular to an anti-crack micro drill bit special for glass and capable of improving work efficiency. A main body of the drill bit is composed of a straight-handle drill rod and a drill bit body, and is characterized in that the straight-handle drill rod is a cylinder and provided with a rectangular locating clamping groove, and the stability of the drill bit can be improved; the joint between the straight-handle drill rod and the drill bit body is sleeved with a gasket, falling impact force in machining can be effectively relieved, and machined workpieces are prevented from being broken.
Description
Technical field
The present invention relates to a kind of semi-finished machining tool, a kind of anticracking micro glass target drill of increasing work efficiency.
Background technology
drill bit goes out through hole or blind hole in order to drilling on processing work, and can to the cutter of existing hole reaming.Drill bit is used in a lot of field, comprise machinery, drilling well, medical, timber, stone, glass etc., and pyrometric cone glass drill is a kind of semi-finished machining tool, aim at glass drilling, and micro glass drill bit belongs to a kind of special drill bit, micro-hole will be got out on frangible glass, and in order to prevent glass to add man-hour cracked, by suitable dynamics, and add water in process engineering, alleviate glass overheated cracked.
Summary of the invention
The object of the invention is to invent a kind of anticracking micro glass target drill of increasing work efficiency.
A kind of anticracking micro glass target drill of increasing work efficiency, main body is made up of staight shank drilling rod and drill body, its innovative point is: described staight shank drilling rod is cylinder, described staight shank drilling rod is provided with rectangle locating groove, described drill body is triangular pyramidal, and described drill body is provided with cutting blade, and described cutting blade is shape of threads, and enclose around drill body one, between described staight shank drilling rod is connected with drill body, cover has pad.
Further, the length of described staight shank drilling rod is 3 ~ 5cm, and diameter is 0.2 ~ 0.5cm.
Further, described drill body is triangular pyramidal, high 0.5 ~ 1.0cm, and diameter is 0.2 ~ 0.5cm.
Further, described cutting blade is one-body molded with drill body.
Further, described rectangle locating groove is located at position after in staight shank drilling rod.
Further, described staight shank drilling rod overlaps to have between being connected with drill body increases flexible circular gasket.
Beneficial effect of the present invention is:
1, staight shank drilling rod of the present invention, through quenching technical process, sturdy and durable, has certain toughness, not fragile.
2, the structure of drill body of the present invention is triangular pyramids, can effectively fit processing work surface, not easy damaged glass surface.
3, drill bit of the present invention is provided with cutting blade, and the design of the angle that cutting blade is carried out and structure, can be good at accelerating cutting speed, increase work efficiency.
4, staight shank drilling rod of the present invention is provided with rectangle locator card and meets with, and can locate the position of drill body accurately, steady drill bit, prevent drill bit from rupturing when High Rotation Speed.
5, when round and elastic pad of the present invention effectively can alleviate processing, the strength of undershoot, prevents processing work from damaging.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
Fig. 1 is structural scheme of mechanism of the present invention.
Fig. 2 is the cutting end view of drill bit of the present invention.
Detailed description of the invention
Straight shank drill as shown in Figure 1, by staight shank drilling rod 1, drill body 2, cutting blade 3, rectangle locating groove 4 and round and elastic packing ring 5 are formed.
The structure of straight shank drill is as shown in Figure 1: staight shank drilling rod 1 is cylinder, and the length of drilling rod is 3 ~ 5cm, and diameter is 0.2 ~ 0.5cm, and handling and the use of straight shank drill are mainly considered in the design of this structure, too shortly not easily installs, oversize poor stability.
One end of straight shank drill is drill body 2 as shown in Figure 1, and drill body 2 front end is provided with a circle cutting blade 3, can accelerate reaming speed, increase work efficiency.
Described staight shank drilling rod 1 has rectangle locating groove 4, during processing work, drill bit can be blocked accurately, steady drill bit, prevent fracture.
During processing work, first at glass underlay one piece of plank, pad jail.Make a sign with the place that marking pen will bore in advance.Staight shank drilling rod 1 is contained on electric hand drill, water water in the place of mark, alignment mark, drill body 2 slowly rotates when just contact processing work is surperficial, Deng processing work occurring after mark, electric hand drill is straightened, cutting blade 3 starts machining workpieces again, then bore several under, notice that brill limit, limit is to boring position water spray, the hole wanting to get out can not collapse limit, then first from boring a part, and then turn-over bores thoroughly.Then be kept on all brill, rock and bore just, will remember when not having water to add water.So just passable.
The above is the preferred embodiment of the present invention, can not limit the interest field of the present invention with this.It should be pointed out that for those skilled in the art, technical scheme of the present invention is modified or equivalent replacement, do not depart from protection scope of the present invention.
