The moving mechanism of engraving machine usefulness long leading screw pair and vibration damping, dust blowing cleaning device
Technical field: a building block of the utility model coefficient control glass engraving machine, particularly the moving mechanism of engraving machine usefulness long leading screw pair and vibration damping, dust blowing cleaning device belong to the glass processing machine.
Background technology: in common Machine Design, long leading screw pair will keep higher limit speed, adopts the leading screw two ends to be strained and fixed usually, the mode that nut rotatablely moves.General design is that nut and axle sleeve are fastening with screw; gear is housed on the axle sleeve; travelling gear rotation, the slide that then drives the dress axle sleeve moves, and the weakness of this frame mode maximum is in the starting of slide fast moving and when stopping; leading screw is long more; the vibration of leading screw self is big more, is unfavorable for running and protection equipment, for this reason; must carry out the vibration damping protection to leading screw, also leading screw be carried out the dust blowing cleaning simultaneously.
Summary of the invention: the purpose of this utility model is to be to provide moving mechanism and the vibration damping, dust blowing cleaning device of a kind of engraving machine with long leading screw pair, it can solve numerical control glass engraving machine long leading screw pair is eliminated vibration when the starting and stopping of bistrique slide end problem, and simultaneously the outer surface of leading screw is carried out the dedusting cleaning, service equipment is had significant role.The utility model is design like this:＜one〉long lead screw moving adopts the synchronous wheel set of driven by motor, and ball-screw nut and axle sleeve are rotated, and drags the translation of bistrique slide.＜two〉end at axle sleeve installs bearing shell cover, folding bearing shell, cleaning sleeve and cleaning ring plate additional.Like this feed screw nut is driven the vibration that axle sleeve rotates the long lead screw of generation at a high speed and carries out vibration damping, and by the cleaning ring plate to leading screw surface dedusting cleaning.Its structural principle is that long lead screw is fixed on engraving machine beam body two ends, and silk is shouldered nut and is connected with screw with synchronous pulley, axle sleeve; Cleaning sleeve, bearing shell cover use screw fastening with the attaching nut, and the attaching nut is contained in the axle sleeve tail end, and wiper ring is contained in the cleaning sleeve, and the folding bearing shell is contained in the bearing shell cover, is located by guider screw.Motor is contained on the slide, when motor rotates, make feed screw nut, axle sleeve, round nut, attaching nut, bearing shell cover by driven by motor synchronous pulley, synchronous band, cleaning sleeve rotates together, the open-close type bearing shell outwards opens at action of centrifugal force lower edge guider screw, when stopping the rotation, bearing shell is under the gravity effect, along guider screw contact leading screw, become the strong point, to the vibration vibration damping of leading screw, cleaning ring is the lip-deep dust of cleaning leading screw in rotation and in moving, and plays the cleaning leading screw.The utility model has the advantages that significantly:＜one simple in structure, stable drive, the leading screw effectiveness in vibration suppression is remarkable.＜two〉the cleaning leading screw is effective.
Description of drawings: following according to the further understanding of accompanying drawing structure of the present utility model.Accompanying drawing 1 is a part sectional plan view of the present utility model.With reference to the accompanying drawings 1 we learn: a kind of engraving machine is with the moving mechanism of long leading screw pair and vibration damping, dust blowing cleaning device, comprise motor 7, motor synchronous belt wheel 3, be with 4 synchronously, parts such as axle sleeve synchronous pulley 5, slide 15, its first design feature is that tubular axle sleeve 6 is connected on the leading screw 1, and axle sleeve 6 front ends connect feed screw nut 2, axle sleeve 6 periphery connecting bushing synchronous pulleys 5, terminal bearing shell cover 10, the cleaning sleeve 13 that connects round nut 8, attaching nut 9, circle of the short cylindrical bodily form.At this moment, starter motor 7 drives the secondary running of one-level synchronous pulley, and drives axle sleeve 6 rotations, and under the cooperation of feed screw nut 2, axle sleeve 6 detours on leading screw 1, drives slide 15 and moves forward and backward, and is very convenient.Second design feature of the present utility model is to overlap 10 middle parts at bearing shell to be connected with guider screw 11, and bearing shell cover 10 is internally connected with open-close type bearing shell 12; Be connected with cleaning ring plate 14 in the cleaning cover 13.When axle sleeve 6 rotations, open-close type bearing shell 12 outwards opens at action of centrifugal force lower edge guider screw 11; When axle sleeve 6 stopped the rotation, bearing shell 12 became the strong point at the effect lower edge of gravity guider screw 11 contact leading screws, and the vibration of leading screw 1 is played damping effect.Simultaneously, the dust on cleaning ring 14 continuous cleaning leading screw 1 surface in rotation and in moving plays cleaning leading screw 1.
Specific embodiments: the utility model discloses a kind of numerical control glass engraving machine with the moving mechanism of long leading screw pair and vibration damping, dust blowing cleaning device, through move (comprise and driving and parking) continuously in the test site, the synchronous wheel set of driven by motor one-level, ball-screw nut and axle sleeve are scratched, drag the bistrique slide and move; The bearing shell cover, folding bearing shell, cleaning sleeve and the cleaning ring plate that install additional at the other end of axle sleeve are scratched the vibration vibration damping of the long lead screw that movable property gives birth at a high speed to feed screw nut, axle sleeve, and by the cleaning ring plate to leading screw surface dedusting cleaning.Through testing hundreds of hours, stable drive, leading screw vibration damping and cleaning effect are good.The utility model is combined on the numerical control glass engraving machine, and its exploitation, application prospect are widely.Simultaneously to adopting long leading screw pair and, all can adopting its principle long lead screw to be solved the vibration damping and the dust removal problem of leading screw by the driving mechanism of feed screw nut moving.
