Abstract
The utility model discloses a dust absorption type hollow drill, which comprises a hollow drill rod. An alloy blade is installed on the head of the hollow drill rod, and a drill hole or a groove communicated with a vacuum air exhaust mechanism is arranged at the rear end of the hollow drill rod. The dust absorption type hollow drill is reasonable in structure and good in dust removal effect, changes an original procedure that compressed air is led in from the center of the hollow drill rod during hole drilling and drilling dust is blown out from a drill hole when a drill rushes out into the procedure that the drilling dust is absorbed in the hollow drill rod, passes through the hollow drill rod to be exhausted a later matched dust absorption separation system, is in favor of continuous drilling-in, removes dust pollution, simultaneously adopts packing seal technology to enable an air distribution ring sleeved outside the drill rod not to rotate when the drill rod is in high-speed rotation, is free of air leakage, guarantees suction vacuum degree, and is particularly suitable to deep hole drills of nonmetal materials, such as graphite materials.
Description
Technical field
The utility model relates to a kind of core drill.
Background technology
When holing, will inevitably produce dust to some brittle non-metallic materials (for example graphite, rock etc.), can adopt usually drill bit, drill hole are sprayed water towards dirt; Or in the drill bit outer ring dust sucting pipeline is set and uses the induced-draught fan dedusting; Can obtain good dust removing effects, but for drilling depth when big, because the dust that drilling goes out is blocked in and resistance is heightened make boring difficult; Therefore the normal core drill that uses hollow steel pipe top welding alloy blade; And in hollow drill logical compressed air, outside utilizing compressed air the powder ejection that goes out of drilling holing in will hole, creep into continuously in order to drilling rod.This method extensively adopts (being about to original drill gun principle is transplanted in the general industry) in China's graphite equipment processing industry.Though the scene generally is employed in drill bit the dust suction of dust suction tube dust catcher is set outward, because whiff pressure is big and concentrated in the drilling rod, and suction port suction is small and scattered, thereby general dust removing effects is not good enough.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of the utility model is to provide, the dust-collecting type core drill of good dedusting effect.
The technical solution of the utility model is:
A kind of dust-collecting type core drill is characterized in that: comprise hollow drill, and the head dress alloy blade of hollow drill, the rear end of hollow drill is provided with boring or the groove that communicates with vacuum suction mechanism.
Said vacuum-pumping system comprises the distribution circle that is wrapped in boring or groove location, and the distribution circle cooperates with vacuum exhaust pipe, outside the distribution circle, gland is set, and distribution circle and drilling rod contact site are provided with the O RunddichtringO.
The utility model is rational in infrastructure, good dedusting effect; When changing original boring compressed air is fed by the hollow drill center; The flow process that when going out the drilling dust is blown out in hole by drill bit; Change into drilling cuttings dust inspiration hollow drill; The dust suction piece-rate system of after drilling rod is sucked into, joining again realizes both having helped creeping into continuously, has eliminated dust pollution again; When adopting the packing seal technology to rotate at a high speed simultaneously, be placed in the outer distribution circle of drilling rod and do not rotate, and realize air tight to guarantee aspiration vacuum level with drilling rod.Be specially adapted to the depth drill of nonmetallic materials, for example graphite material.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the structural representation of an embodiment of the utility model.
The specific embodiment
A kind of through after join the dust-collecting type core drill of vacuum cleaner system and will be originally feed in the hollow drill so that smear metal (dust) is blown out outside the hole through gap, drill bit place by compressed air, change into vacuum smear metal by suction in the hollow drill and by the vacuum separation system of joining after being drawn in the drilling rod.This core drill is welding alloy blade 1 on the seamless steel pipe top, and drilling rod tail end welding shutoff is air tight, and the boring in the appropriate location, rear portion (or fluting) is so that bleed; The distribution circle is wrapped in boring or groove location, and behind the distribution circle that is welded with vacuum exhaust pipe 65 cooperation location, then the drilling rod axle center obtains the location; Utilize the screw thread on distribution circle 5 and the gland 4; Can will be placed in outer two round section joint rings 3 or the filler of drilling rod 2 compress, like this, do not rotate situation at distribution circle 5, gland 4 and round section joint ring 3; Realize sealing when drilling rod rotates at a high speed air tight; When the drilling rod drilling because of vacuum draw realize with smear metal by hollow drill in boring (or fluting) through above-mentioned rear portion, and be placed in the distribution circle of this outside, place, the dust suction piece-rate system of joining after pumping to.Distribution circle 5 then should or be retreated with the drilling rod advanced in unison, the cylindrical of hollow drill 2, and the rear portion needs to realize movingly with very little negative common difference with distribution circle 5 endoporus, and plays stable pivotal role; Front end then can be the light wall, also can process helicla flute to strengthen the ventilation sectional area; The centering of drilling rod front end can be adopted the blade outer rim centering of depth drill, also can be simultaneously in four guide pad centering of drilling rod front end weldering (or edge).For guaranteeing to be drawn into air and the friction that prevents drilling rod and hole wall by gap between drilling rod and boring, the drilling rod cylindrical must be less than the blade cylindrical, for example little 1 ~ 2mm.When drilling depth is big, also can set up 3 ~ 4 guide pads, to reduce the vibration of drilling rod in drilling rod a part.Also has workpiece 7 among the figure.
Claims (2)
