Description
Technical field
The utility model relates to a kind of semi-finished machining tool, a kind of high efficiency Quick-type hard plank Special hollow drill head.
Background technology
Core drill is the form adopting multi-blade ring-type to cut, utilize the external diameter annulus of a drill bit cutting hole, do not cut mid portion, thus substantially increase drilling efficiency, and in conjunction with magnetic support rig etc., on-the-spot bore operation at any time can be realized, relative to common fluted drill, efficiency is more increased, and cuts brisk.Lignum vitae sheet material matter is comparatively hard, adds and easily occurs the situation that burr is too much man-hour, and hard plank Special hollow drill head can be good at processing, reduces a large amount of burrs, thus reduces unnecessary following process.
Utility model content
The purpose of this utility model is a kind of high efficiency Quick-type hard plank Special hollow drill head of utility model.
A kind of high efficiency Quick-type hard plank Special hollow drill head, main body is made up of drill body and staight shank drilling rod, its feature innovative point is: described drill body is hollow cylinder, described drill body is provided with cutting blade, described staight shank drilling rod is cylinder, and described staight shank drilling rod inside is provided with fastening screw pit.
Further, the length of described drill body is 1.0cm ~ 2.0cm, and diameter is 4.0cm ~ 6.0cm; Structure be hollow cylinder and front end for being provided with cutting blade.
Further, described drill body is provided with cutting blade, and the structure of cutting blade is cuboid zigzag.
Further, cutting blade rear end is provided with diamond gravel, and gravel is impalpable texture.
Further, the length of described staight shank drilling rod is 4.0cm ~ 6.0cm, and diameter is 5.0cm ~ 7.0cm; Structure is cylinder.
Further, described staight shank drilling rod inside is provided with fastening screw pit, and it is inner that screw thread is distributed in staight shank drilling rod, and dark 2 .0cm ~ 3.0 cm, diameter is 2.0 cm ~ 3.0 cm.
The beneficial effects of the utility model are:
1, drill body described in the utility model, through glossing process, smooth surface, is beneficial to processing, also meets aesthetic standard; Through quenching technical, there is certain toughness, not fragile, one-body molded, more sturdy and durable.
2, drill body described in the utility model is provided with cutting blade, structure is cuboid zigzag, cutting blade rear end is provided with diamond gravel, can friction slip be prevented, also can auxiliary cutting edge process.
3, staight shank drilling rod inside described in the utility model is provided with fastening screw pit, can coordinate perfection with fixture, more fastening.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
Fig. 1 is structural scheme of mechanism of the present utility model.
Fig. 2 is the cutting end view of the utility model drill bit.
Detailed description of the invention
Hollow boring bit as shown in Figure 1, is made up of staight shank drilling rod 1, drill body 2, cutting blade 3, diamond gravel 4 and fastening screw pit 5.
The structure of straight shank drill is as shown in Figure 1: staight shank drilling rod 1 is cylinder, and the length of described staight shank drilling rod is 4.0cm ~ 6.0cm, and diameter is 5.0cm ~ 7.0cm, installs stable.
As shown in Figure 1: staight shank drilling rod is provided with fastening screw pit 5, screw thread and fixture perfect cooperation, more fastening.
One end of straight shank drill is drill body 2 as shown in Figure 1, for hollow cylinder, drill body 2 is provided with cutting blade 3, cutting blade 3 structure cuboid zigzag, and cutting blade rear end is provided with diamond gravel, can friction slip be prevented, also auxiliary cutting edge can process, effectively increase work efficiency.
During processing work, make a sign with the place that marking pen will bore in advance.Fastening screw pit 5 is screwed in fixture, install fastening after, alignment mark, cutting blade 3 first contacts processing work, slowly rotating, when there is mark, accelerating rotary speed, diamond gravel 4 can secondary process, as the situation of boring to go down, need wood chip in first cleaning eye, then continue boring, through after a period of time, machine.
The above is preferred embodiment of the present utility model, can not limit the interest field of the utility model with this.It should be pointed out that for those skilled in the art, the technical solution of the utility model is modified or equivalent replacement, do not depart from protection domain of the present utility model.
