Description

A kind of fine-tuning drilling device
Technical field
The present invention relates to lathe drilling field, more particularly to a kind of fine-tuning drilling device.
Background technology
Drilling is common technological means in mechanical processing, needs first to be clamped workpiece when drilling to workpiece solid It is fixed, since the position of clamping device is fixed, if after workpiece has flaw to cause clamping device to fix workpiece, workpiece needs to bore The position in hole is not corresponding with drill bit, and workpiece machining error will be made to become larger, so as to substandard product occur, causes unnecessary wave Take.In addition, also needing to carry out chip removal collection processing during work pieces process, prevent chip sputtering from influencing the working environment of surrounding.
The content of the invention
The invention is intended to provide a kind of fine-tuning drilling device, to improve machining accuracy when drilling.
To reach above-mentioned purpose, base case of the invention is as follows：
A kind of fine-tuning drilling device, including stent, borehole drill construction, clamping device, the borehole drill construction include planetary gear Bore motor, the flabellum that system, driving planetary gear train rotate, bore motor are fixed on stent, and the planetary gear train includes the sun Wheel, circumferential planetary gear, gear ring and the planet carrier being uniformly engaged on sun gear, the output shaft and sun gear of bore motor are coaxially solid It is fixed, the drilling rod and drill bit for drilling are installed on planetary gear；The gear ring is divided into the engaging piece engaged with planetary gear and puts down Cunning portion, the end-enclosed of the partes glabra, the flabellum are coaxially mounted on the inside of partes glabra；The planet carrier is by sun gear and row The tooth of star-wheel wraps up and leaves the ventilation hole for allowing gear ring both ends to connect, and planet carrier is rotatably connected on gear ring inner wall；Break away outside gear ring It is dynamic to be connected with outer barrel, it is slidably connected on the inside of the outer barrel with planet carrier, outer drum outer wall is rotatably coupled on stent；The folder Holding mechanism includes rack-mount slide, the locating rack that is slidably connected on slide, the locating rack and drilling rod it is opposite The clamping part of clamping workpiece is installed, the clamping part includes the clamping jaw being slidably connected on locating rack and promotes clamping jaw to slide on face Dynamic air bag；The air bag is connected by pipeline with the partes glabra of gear ring；The through hole of chip removal is provided with the official road.
The principle of this programme is：Between workpiece is placed on clamping jaw, start bore motor, bore motor is rotated so as to successively Sun gear, planetary gear and gear ring high-speed rotation are driven, the flabellum on the inside of gear ring partes glabra is fixed on and rotates to be formed and flow in pipeline Air-flow so as to blow air into air bag, the air bag of expansion will promote clamping jaw to step up to fix by workpiece；Loosening fasteners, fine setting turn Dynamic outer barrel, outer barrel drive planet carrier to rotate from the fine setting for realizing planetary gear, make drill bit corresponding with the bore position of workpiece；Start gas Cylinder, cylinder promote locating rack to promote workpiece to borehole drill construction；When outer barrel and workpiece are adjacent to, workpiece, outer barrel, gear ring form one A chamber that can only enter air from air admission hole, cavity are interior formed with the air-flow in outer barrel to pipeline；Locating rack continues to promote, and pushes away Dynamic outer barrel slides, and drill bit drills with workpiece contact start, and the chip produced during drilling is by air-flow intake line, and from pipeline On chip-removal hole discharge.
The advantages of this programme, is：(1) by rotating adjustment outer barrel so as to drive planet carrier to rotate, the planet carrier band of rotation Dynamic planetary gear trim locations, improve the machining accuracy of workpiece；(2) since the inner wall of gear ring is equipped with flabellum, gear ring high-speed rotation When flabellum can be driven to rotate, so as to form one air-flow, air-flow can make air bag expansion realize the effect of fixed workpiece, together When air-flow can also by chip intake line caused by drilling, avoid chip splash influence workshop working environment, reduce Clearance time；The air-flow constantly flowed into can also reduce the temperature of drilling rod, play the role of protecting drilling rod.
Further, the clamping jaw afterbody has the cylinder barrel for accommodating air bag, and the cylinder barrel is fixed on locating rack, and clamping jaw, which slides, to be connected It is connected in the cavity of cylinder bucket, preferably clamping jaw can be promoted to consolidate workpiece when the air bag being located in cylinder bucket is hardly damaged and expands It is fixed.
Further, the strainer for preventing chip from entering air bag is installed on the pipeline, avoids chip from damaging air bag.
Further, resetting spring is installed, after the completion of work pieces process, resetting spring can be between the planet carrier and outer barrel Outer barrel is back into initial position, easy to reuse.
Further, the end of the outer barrel is equipped with sealing ring, workpiece is fitted closely with outer barrel, avoids chip from leaking out Go.
Further, there is the cushion block of support gear ring on the stent, the gear ring is rotatablely connected with cushion block, reduces bore motor The support pressure of output shaft.
