Description

The automatic dust absorption air drill

Technical field: the invention is to mill at composites such as carbon fiber, fiberglass, increase the dust suction member on the employed air drills of processing such as brill, hinge.

Background technology: because the development of technology, carbon fiber, composites such as fiberglass are in space flight, on the aeronautical product, be used manufacture component widely in automobile and other industries, milling limit clout in component processing, boring, can produce toxic dust during fraising, these dust fall on the ground a bit, some swims in the air as smog, contaminated environment not only, and it is very harmful to human body, be used to process carbon fiber at present, the employed air drill of composites such as fiberglass, there is not the dust suction member, there is not dust-absorbing function, the dust that is produced in the process is stayed processing site, concentrates cleaning during to be processed finishing again, have for cleaning dust in processing, to underworker of each process operation person additional configuration and a high power vacuum cleaner, not only wasted manpower, material resources, dedusting are also undesirable, and it is extremely inconvenient to work together.

Summary of the invention: the purpose of the invention provide a kind of to composites such as carbon fiber, fiberglass mill, brill, hinge etc. add man-hour, can absorb dust simultaneously, realize dedusting, reduce processing site environment and air-polluting automatic dust absorption air drill; The purpose of the invention is achieved through the following technical solutions: the automatic dust absorption air drill: comprise air drill, transit joint, hydraulic quick coupler, it is characterized in that the automatic dust absorption air drill is made of suction pipe, spring, flexible dust cover, adapter sleeve, sealing ring, tube connector, joint, valve body, transmitting tube, adjusting airduct, locking nut, upper end cover, dividing plate, damper tube, bottom end cover, dust bag, transition joint, three-way connection, pipe joint, air intake control valve, hydraulic quick coupler, air drill; The transit joint spiral shell is contained on the handle of air drill, transit joint other end spiral shell dress three-way connection, the three-way connection inlet end is installed hydraulic quick coupler, another outlet side mounting pipe joint of three-way connection, be installed into gas control valve on the pipe joint, valve body is installed in the pipe joint outlet side, valve body is made three-port structure, in the inner chamber of valve body upper end, transmitting tube is installed, the cone-shaped structure is made in the transmitting tube lower end, the valve body lower end inner chamber is installed and is regulated airduct, regulate airduct upper end inner chamber and make inner cone shape endoporus, regulate the airduct lower end and make bell mouth shape, on the horn mouth wall, make circular hole, transmitting tube lower end cone-shaped pipe end is inserted into to be regulated in the airduct inner cone shape endoporus, the transmitting tube outer wall leaves the gap with adjusting airduct inwall cooperation place, dividing plate is installed in the lower end horn mouth of regulating airduct, upper end cover is installed in adjusting airduct horn mouth place, damper tube is contained in the bottom end cover, the bottom end cover spiral shell is contained on the upper end cover, regulate airduct, damper tube and last, form cavity between the bottom end cover, make circular hole on damper tube sidewall and the following top end wall, dust bag is installed on the valve body by locking nut, sealing ring is installed on the adapter sleeve inwall, adapter sleeve is installed on the air drill, spring is installed on the adapter sleeve, and the dust cover that will stretch is sleeved on the spring outside and is installed on the adapter sleeve, and suction pipe is installed on the flexible dust cover, suction pipe exposes the end and is shaped on circular hole, the tube connector two ends be separately fixed on the adapter sleeve with joint and valve body on.

Suction pipe adopts lucite to make.

Transmitting tube cone-shaped outer wall stays 0.1～0.5mm gap with adjusting airduct inner conical inner hole wall cooperation place.

Automatic dust absorption air drill processing carbon fiber, while dust removal process during composites such as fiberglass: hydraulic quick coupler is connected with source of the gas, compressed air enters three-way connection from hydraulic quick coupler, the three-way connection inner chamber is divided into two passages, a passage enters air drill as power source, make the rotor rotation in the air drill, driving process tool processes parts, another paths enters pipe joint, open air intake control valve, compressed air enters body cavity, compressed air enters from transmitting tube and the space of regulating the 0.1～0.5mm that stays between the airduct and regulates the airduct inner chamber, compressed air is under the situation that 0.1～0.5mm clearance channel diminishes, velocity of compressed air improves, in suction pipe, produce negative pressure, the dust that processing is produced sucks suction pipe through flexible dust cover, adapter sleeve, the tube connector inner chamber enters in the transmitting tube, under the drive of compressed air, enter and regulate the airduct inner chamber, when air-flow arrives the horn mouth inner chamber, because it is big that the space becomes, air-flow velocity slows down, under the effect of dividing plate, the circular hole changed course of air-flow from the horn mouth wall flows to the cavity, the air-flow circular hole on the damper tube sidewall again enters the damper tube inner chamber, air-flow slows down again, air-flow again under damper tube the circular hole on the top end wall enter in the dust bag, air-flow is through three dampings, promptly repeatedly change airflow direction, dwindle air communication again and again and cross section, and return multiple process with what section enlarged, and air-flow is divided into a lot of sprouts, flowed along rough plane in the tributary, speed reduces significantly, the air current flow energy is consumed, and reduces exhaust noise, and the dust in the air-flow separates from air-flow and concentrates in the dust bag.

The advantage of the invention: owing on pneumatic tools, increased the dust suction member, when composite elements such as carbon fiber, fiberglass are milled, cut processing, brill, fraising add the dust that produces man-hour and are entered in the dust bag by suction pipe, by centralized collection, processing site environment and air are not produced pollution, avoided the harm of dust human body; The automatic dust absorption air drill, simple in structure, assembling with use all easily, add man-hour, as long as dust suction when opening air intake control valve and just can realize processing, the saving human and material resources cut down finished cost.
