Embodiment
As shown in drawings, the present invention includes movable base plate 27, movable base plate 27 bottoms are provided with left slider 32 and right side slide block 29, can in the groove of frame 28, slide; Fixed four of movable base plate 27 upper surfaces are arranged symmetrically with guide rod 26, and movable base plate 27 upper surface left sides and right side be fixed left bearing 12 and right bearing 21 respectively.On four guide rods 26, be set with spring 25, guide rod 26 is slidably matched by slide block 24 and stamp work platform 23, stamp work platform 23 left sides are provided with the second screw mandrel 11 and print a 10(rack cutter machining simulation seal 10 inner a setting containing big basin-like inkstone silk floss 38 with rack cutter machining simulation, top is furnished with oil hole 37, bottom prints 39 pairs of cloth by ink and wraps up containing big basin-like inkstone continuous 38 and flank profil " blade " periphery), the second screw mandrel 11 left ends are supported by the second bearing 31, and right-hand member is connected with stepper motor 22 by shaft coupling; On movable base plate, be fixed with machine operation platform 30, direct current generator 16 is installed on machine operation platform 30, direct current generator 16 is by the first conical gear 14 and the second conical gear 15 transmitting torques, and drive installation is at the main shaft 20 of left bearing 12 and right bearing 21.On main shaft 20, be fixed with left cam 13, right cam 19 and partial gear 18, promote stamp work platform 23 and move up and down along guide rod 26 when left cam 13 and right cam 19 synchronous rotation, partial gear 18 coordinates with incomplete tooth bar 17.Input keyboard, screen and associated circuit board are installed in frame 28 tops, direct current generator 16 and stepper motor 22 are controlled, the chute 34 that frame 28 left ends arrange coordinates slip with bracket 35, and the position that utilizes the register pin of horizontal direction to realize 35, chute 34 and bracket is located and fixes.Clutch shaft bearing 1 is arranged on bracket 35, gear back shaft 7 bottoms are arranged in clutch shaft bearing 1, gear back shaft 7 middle parts are fixedly mounted with pallet 3 and gear 2, its middle gear 2 and mobile rack 33 engaged transmission, gear back shaft 7 middle parts have threaded portion that platen dish 8 is installed, upper cone profile shaft section place cover has on the first screw mandrel 6, the first screw mandrels 6 installs pivoted arm 5, and it is that the cutter other end is an Intermediate Gray mounting hole that pivoted arm 5 front ends are installed combination writing of indictments, appeals, etc. 4(one end).
Use when of the present invention, first extract register pin 41, the main worktable that movable support bracket 35 forms gear 2, pallet 3 moves to left, and allows gear 2 depart from mobile racks 33; Ground paper 9 is placed on pallet 3, screws 8 pairs of ground paper 9 of platen dish and position compression.Circular cone through hole on the first screw mandrel 6 in the setting-out cutting mechanism consisting of the first screw mandrel 6, pivoted arm 5, the combination writing of indictments, appeals, etc. 4 is enclosed within to the upper end of gear back shaft 7; By rotation pivoted arm 5(, it is marked with length scale) regulate the distance of nib and gear back shaft 7 axle center in the combination writing of indictments, appeals, etc. 4, by holding paintbrush, around gear back shaft 7, rotate the drafting that realizes preliminary dimension reference circle.Complete after reference circle drafting, writing of indictments, appeals, etc. switching is carried out in the rotation combination writing of indictments, appeals, etc. 4, allows point of a knife around gear back shaft 7, rotate respectively the semi-circumference cutting that half cycle is realized master gear and predetermined X-gear point circle on ground paper 9.Complete after above-mentioned work, take out setting-out cutting mechanism, the bracket 35 that moves right, inserts register pin 41 and resets, and makes gear 2 and mobile rack 33 standard engagements, adjusts tangent in its semi-circumference midpoint and tooth bar " slotting tool " center line by the accurate gear compound graduation circle of trimscript.The register pin 41 that bracket 35 and chute are 34, phase mutual edge distance change in the time of can preventing gear 2, mobile rack 33 engaged transmission.Again mobile rack 33 is pushed into the extreme position at mobile two ends.
Then start direct current generator 16, by the first conical gear 14 and the second conical gear 15, drive respectively the left cam 13, partial gear 18, the right cam 19 that are fixed on main shaft 20 synchronously to rotate.Left cam 13 and right cam 19 are in rise motion, press stamp work platform 23, the rack cutter machining simulation that promotion is connected to stamp work platform 23 left sides by screw pair prints 10 and moves downward, and makes it on ground paper 9, print off ink tool marks, thereby realizes the cutting simulation of tooth bar " slotting tool "; The elastic force that utilizes spring 25 to produce in left cam 13 and right cam 19 drawback movements promotes stamp work platform 23 and resets.The incomplete tooth bar 17 of partial gear 18 pushing in left cam 13 and right cam 19 drawback movements, because incomplete tooth bar 17 is fixed in frame 28, utilize relative motion principle, partial gear 18 just drives movable base plate 27 and stamp work platform 23 above and machine operation platform 30 thereof to move horizontally a bit of distance, and mobile rack 33 driven wheels 2 in movable base plate 27 left sides and ground paper 9 rotate a corresponding angle and realize rolling movement simultaneously.After ground paper 9 rotates, not exclusively the locking arc on tooth bar 17 36 pins partial gears 18, makes it when rack cutter machining simulation prints a 10 impression ground paper, guarantee that movable base plate 27 is static.The above-mentioned motion of periodic cycle just can impress out a series of ink tool marks on ground paper 9, realizes generation method simulation of gear machining fast and accurately.In motion process, use limit switch to control the front and back stroke of movable base plate 27.
Complete after master gear drafting, unscrew platen dish 8, after being rotated to 180 degree, ground paper compresses, in keyboard, input predetermined modification coefficient, press the switch activated stepper motor 22 of displacement, stepper motor 22 drives the second screw mandrel 11 to rotate by shaft coupling, realizes rack cutter machining simulation and prints 10 displacement accurately, again start direct current generator 16 and realize complete machine backhaul impression, emulation completes the processing of X-gear.Test rear powered-down, allowed bracket 35 skid off main worktable, taken off the ground paper 9 of drafting.
Within not being described in detail in this instructions, hold for the known prior art of professional and technical personnel in the field.
