Abstract
The invention discloses a double-gear-rack driving deep hole trepanning feed driving mechanism with a differential gear and belongs to the technical field of machine tool feed mechanisms. A drill pipe feed box is mounted on a drill pipe feed sliding plate to provide power for feeding and fast moving of a drill pipe. The drill pipe feed box is driven by a DC motor and is sped down through a return bend mechanism, and power is transferred to a left worm and gear case and a right worm and gear case from output shafts at the two ends through a planetary mechanism. A bevel gear in the left worm and gear case is engaged with a bed body left-hand rack, and a bevel gear in the right worm and gear case is engaged with a bed body right-hand rack, so that the drill pipe feed sliding plate is made to move longitudinally. When the gear of the worm and gear case and the rack on one side conduct driving out of sync, synchronous operation is achieved through compensation of the planetary mechanism. By adopting the double-gear-rack driving deep hole trepanning feed driving mechanism, the problem that a left bevel gear and a right bevel gear of a drill pipe feed box of a heave-duty deep hole drilling and boring machine conduct engagement driving with a left bed body helical rack and a right bed body helical rack simultaneously but non-synchronously during trepanning is solved.
Description
Technical field
The present invention relates to a kind of deep hole jacking feeding driving mechanism with differential gear double-rack-and-pinion drive, belong to machine tool feeding mechanism technical field.
Background technology
Be presently used for maximum set blanking aperture φ 700mm, the heavy deep hole drilling and boring machine of maximum jacking length 10000mm also belongs to internal blank, and one of key technology retraining its development processes feeding structure exactly.Arranging large modulus helical rack in bed piece arranged on left and right sides, deep hole jacking feed mechanism needs left and right two helical gears to engage respectively with lathe bed arranged on left and right sides helical rack simultaneously, but Rack and gear transmission asynchronous problem in both sides when there is feeding.For solving this problem, devise a kind of with differential gear, the deep hole jacking feeding driving mechanism of double-rack-and-pinion drive.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of with differential gear, the deep hole jacking feeding driving mechanism of double-rack-and-pinion drive, solve left and right two helical gears of heavy deep hole drilling and boring machine drilling rod feed box in overlaying processing simultaneously with the lathe bed arranged on left and right sides nonsynchronous difficult problem of helical rack engaged transmission.
The technical solution adopted for the present invention to solve the technical problems is: drilling rod feed box is arranged on drilling rod feed slide, for drilling rod feeding and the most mobile offer power.Drilling rod feed box is by a DC motor Driver, through Hui Qu mechanism reduction of speed, then through planetary mechanism, by two ends output shaft, power is reached left worm gear case and right worm gear case.Helical gear in left worm gear case helical rack left-handed with lathe bed engages, and the helical gear in right worm gear case engages with lathe bed dextrorotation helical rack, it is achieved drilling rod feed slide vertically moves.When wherein worm gear case Rack and gear transmission in side is asynchronous, compensates through planetary mechanism and reach to run synchronization.Hui Qu mechanism and planetary mechanism are absolute construction, are arranged in drilling rod feed box body.Feeding chain in Hui Qu mechanism is realized by electromagnetic clutch A and electromagnetic clutch B with the switching of quick chain.Left worm gear case and right worm gear case are independent case body, are arranged in drilling rod feed slide rearmost end, with screw with drilling rod feed slide body closing.
The invention has the beneficial effects as follows: the present invention solve left and right two helical gears of heavy deep hole drilling and boring machine drilling rod feed box in overlaying processing simultaneously with the lathe bed arranged on left and right sides nonsynchronous difficult problem of helical rack engaged transmission.
