Description
(1) technical field
The utility model relates to a kind of sander, especially relates to a kind of hand-held drill pipe bore sander, is used for the polishing of drill pipe bore.
(2) background technology
At present, polishing for drill pipe bore, usually need to use large-scale sander equipment, complicated operation not only, and because equipment is maximization equipment, can't move, when the polishing endoporus, need mobile drilling rod, increased manufacturing procedure, influenced production efficiency to ad-hoc location, simultaneously, this type of main equipment tends to expend a large amount of electric energy.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of simple in structure, conveniently moving is provided and has the hand-held drill pipe bore sander of energy-saving effect,
The purpose of this utility model is achieved in that a kind of hand-held drill pipe bore sander, include confined chamber, bull stick and air motor, be respectively arranged with left sealing cap and right aling cap about described confined chamber, be provided with some handles between described left sealing cap and the right aling cap, described right aling cap center is connected with a suction nozzle, described air motor is fixedly set in the confined chamber, and the air inlet of described air motor links to each other with suction nozzle, described bull stick one end is with an emery wheel, the other end links to each other with the output of air motor, be provided with a bearing between described bull stick and the confined chamber, described bull stick center has an outlet passageway, described bull stick is positioned on the distolateral wall of confined chamber and has a venthole, and described outlet passageway is connected with venthole.
The beneficial effects of the utility model are:
(1) adopts air motor to drive bull stick and rotate, compare, have more energy-saving effect with traditional motor-driven.
(2) behind the employing air motor, structure is simplified greatly, can carry out hand-held easily.
(3) compare with traditional maximization equipment, operate more flexibly, improved production efficiency greatly.
(4) in the course of work, Compressed Gas is got rid of by the gas outlet of starter after the venthole of bull stick and initial stage passage when discharging, can blow out the dust that produces in the bruting process, has guaranteed the cleannes of drill pipe bore.
