Abstract
The present invention relates to a dovetail head for a combined flat plate digital controlled cutting and drawing machine. The present invention belongs to a component in a digital controlled combined flat plate type cutting and drawing machine. The present invention aims at providing a dovetail head for a combined flat plate digital controlled cutting and drawing machine so as to realize the transformation of a pen and a cutter by adopting a dovetail type driving slide bar. The present invention is characterized in that the dovetail head is provided with a step motor; an eccentric wheel is arranged on a shaft of the motor, and a connecting rod is coaxially connected with the shaft of the motor; a cutter rod, a cutter holder, a pen rod and a pen holder are arranged on a slide block seat; the present invention is also provided with a slide block, a slide block steering connection plate, a locking screw rod, an adjusting bolt, a photoelectric cell, etc. The dovetail type driving slide bar can realize the transformation of a cutter and a pen and can conveniently adjust a gap between the cutter and the pen. The present invention is favorable to the elimination of partial mechanical processing errors. The present invention has the advantages of compact structure, small volume, high intensity, abrasion resistance, low noise, high precision and long service life. The present invention only needs one motor and a set of transmission mechanisms.
Description
Technical field
The invention belongs to the parts in the cutting drawing machinery of assembled flat formula of numerical control.
Background technology
Head is the crucial parts of assembled flat digital controlled cutting and drawing apparatus, and it drives the motion and the conversion of the writing of indictments, appeals, etc.Domestic existing head that several small-sized cutting and drawing apparatus is joined generally all is to adopt stepper motor two ends that output shaft is all arranged in the design now, and a sets of transmission mechanism is installed separately, is mutually 180 degree corners; The writing of indictments, appeals, etc. drives respectively, adorns slide block and outer toolsetting location outward.This rotating by a stepper motor, the major defect of structure that drives cutter and the slide block of pen by motor two ends output shaft respectively is: driving motor needs specific model; Structure is complicated, and volume is big, and fault is more and heavy, and precision is not high.
Summary of the invention
The object of the present invention is to provide a kind of dovetail groove type that adopts to drive the assembled flat digital controlled cutting and drawing apparatus dovetail head that draw runner is realized writing of indictments, appeals, etc. conversion.The present invention finishes with following mode: a kind of assembled flat digital controlled cutting and drawing apparatus dovetail head, it is characterized in that it has a stepper motor 1, and on 1 of stepper motor, eccentric wheel 3 is housed, these eccentric wheel 3 coaxial connection connecting rods 4; Connecting rod 4 one sides are equipped with take-up housing 11, and knife bar 5, cutter holder 6 and penholder 8, pen clip 7 are installed; Take-up housing 11 back also are connected with slide block and turn to yoke plate 13; Take-up housing about 11 respectively is equipped with a slide block 9 respectively, is respectively left slider and right slide block; Cutter holder 6 pen clips 7 also are connected with two tie down screws 12, also are equipped with in take-up housing 11 both sides to adjust bolt 10; There is the centrally aligned of a breach and photoelectric tube 2 at above-mentioned cutter holder 6 and pen clip 7 places, on same center line at grade the time on the eccentric wheel 3.The present invention relatively has the following advantages with similar technology Related product: (1) adopts a stepper motor single-ended drive, does not need the specific model motor, can select general general-purpose machine for use.(2) adopt two dovetail link rod structures, rearmounted slide block turns to yoke plate, and this dovetail groove type drives draw runner and realizes writing of indictments, appeals, etc. conversion, and can conveniently regulate cutter, a gap, helps eliminating the part machining error.Material adopts spheroidal graphite cast-iron, the moulding of warp cutting processing; Have compact conformation, volume is little, the intensity height, and wear-resisting, noise is low, precision height, characteristics such as long service life.(3) only need a sets of transmission mechanism, so simple in structure, the chance that breaks down obviously reduces.
Description of drawings
Fig. 1-Fig. 3 is a structural representation of the present invention: wherein Fig. 1 is a front view; Fig. 2 is a vertical view; Fig. 3 is a left view.
The specific embodiment
Now the present invention is described in further detail in conjunction with the accompanying drawings.With reference to Fig. 1-Fig. 3, the assembled flat digital controlled cutting and drawing apparatus dovetail head is that the cutter that adopts a stepper motor 1 to drive to install on the take-up housing 11 and pen move up and down and carry out work, its use principle and the course of work are as follows: after stepper motor 1 receives pulse signal, adjust its duty with pulse signal, by 3 drivening rods 4 of the eccentric wheel on the motor shaft and left slider 9 moving linearlies, cutter holder of installing on the left slider 96 and knife bar 5 are along with the motion of slide block 9 is cut or withdrawing, 8 slide blocks by take-up housing 11 back of penholder turn to yoke plate 13 and knife bar 5 to make reverse motions, promptly start writing and start to write.Eccentric wheel 3 is rotated counterclockwise during starting, and knife bar 5 and penholder 8 return to the equilbrium position, and promptly cutter holder 6 and pen clip 7 places are at grade.The center of the notch alignment photoelectric tube 2 on the eccentric wheel 3; During operate as normal, the rotation of eccentric wheel 3 clockwises drives knife bar 5 and penholder 8 and moves up and down.Whenever after finishing a procedure, knife bar 5 and penholder 8 all return to the equilbrium position.On the plane of cutter holder 6 and pen clip 7, mill one and adjusted groove, be used to adjust the height of workpiece on knife bar 5 and penholder 8 and the table top.Respectively there are 2 hexagon socket head cap screws the both sides of take-up housing 11, turn bolt and can adjust gap between slide block 9 and the take-up housing 11, reduce the operating error that knife bar 5 or penholder 8 produce because of the excesssive gap of slide block 9 and take-up housing 11.The depth of feed is realized by the adjusting by the gear size of the keyboard of assembled flat digital controlled cutting and drawing apparatus, can the material of different-thickness be cut or draw.The assembled flat digital controlled cutting and drawing apparatus that the present invention is adapted to various models uses.
