In order to control the conveying one by one of workpiece, feeding groove is extending out the discoidal turned cavities 11 of formation near feed well place, the sub-material rotating disk 12 of one circle is set in turned cavities, this sub-material rotating disk is by the driving stepper motor be located at outside feeding groove, to make it can by the angular turn arranged in advance in turned cavities, the circumferentially decile of sub-material rotating disk arranges two sub-material bayonet sockets 121, sub-material bayonet socket is radially extended internally by the edge of sub-material rotating disk, the width of sub-material bayonet socket and the external diameter adaptation of workpiece, its base is semicircle, and the degree of depth of sub-material bayonet socket equals the 1-1.2 of workpiece external diameter doubly, preferred value is 1.1 times.The line of two sub-material bayonet sockets and the central axes of feeding groove, like this, a sub-material bayonet socket just aims at feeding groove near workpiece inlet side, another sub-material bayonet socket is then just aimed at feeding groove and is connected feed well side, when workpiece rolls downwards along feeding groove, first enter into and aim at feeding groove in the sub-material bayonet socket of workpiece inlet side, and just can only hold a workpiece in sub-material bayonet socket, during stepper motor drive sub-material dial rotation, feeding groove is shut by sub-material rotating disk, namely the subsequent workpiece be affixed with the workpiece in sub-material bayonet socket is blocked in feeding groove, after sub-material rotating disk turns over 180 degree, originally the sub-material bayonet socket of alignment pieces inlet side forwards to and aims at feeding groove connection feed well side, now, the workpiece of its inside can roll downwards under gravity and enter in feed well, originally the sub-material bayonet socket then rotational alignment workpiece inlet side that feeding groove connects feed well side is aimed at, follow-up workpiece can enter in this sub-material bayonet socket, repetition like this, workpiece can be sent in feed well one by one.Certainly, we can also arrange two to opposite polarity permanent magnet 122 at the madial wall correspondence position of the edge of sub-material rotating disk and turned cavities, the layout and two pairs of permanent magnets are centrosymmetric, utilize the suction of permanent magnet, can guarantee that sub-material rotating disk can be positioned at accurately on position in a free state, when working, stepper motor then can overcome this suction and rotates.
In addition, in order to workpiece is pushed to locating slot inner position, we also need arrange corresponding workpiece pusher 5 to one end that feeding groove connects in feed well, as shown in Figure 3, workpiece pusher comprises one and is slidably arranged in the arc push pedal 51 in feed well and drives arc push pedal to push cylinder 52, arc push pedal side is the propelling movement face 511 of indent, propelling movement face is preferably the face of cylinder with workpiece external diameter adaptation, opposite side is rotationally connected by rotating shaft 53 with the piston rod pushing cylinder, simultaneously, axis hole 512 inwall of arc push pedal accommodation rotating shaft arranges the stopper slot 513 along the circumferential direction arranged, and correspondingly in rotating shaft corresponding stopper slot place radial position-limitting pin 531 is set, position-limitting pin extend in stopper slot, by reasonably arranging the size of stopper slot, the rotational angle of arc push pedal can be limited.Certainly; be understandable that; need to arrange alignment pin or holding screw etc. between above-mentioned rotating shaft and piston rod, to make can not produce relative rotation between rotating shaft and piston rod, thus guarantee to rotate between two extreme positions that can limit at stopper slot between arc push pedal and piston rod.
Further, we also need arrange torsion spring (not shown) in rotating shaft, one end pins piston rod, the other end pins arc push pedal, make arc push pedal can turn to side extreme position under the effect of torsion spring, the propelling movement of arc push pedal is now facing to the vertical consistency with feed well, and the face that namely pushes becomes symmetry shape on the central axis of feed well longitudinal direction.When arc push pedal turns to another extreme position, arc push pedal be oriented horizontal direction, thus can completely towards the locating slot of level.Certainly, we need to arrange draw-in groove 21 along its length in feed well bottom surface, and corresponding draw-in groove place arranges the driving lever 514 goed deep in draw-in groove at the edge of the downside of arc push pedal, like this, form between driving lever and draw-in groove and be slidably connected, thus guide effect is played to the slip of arc push pedal in feed well, simultaneously, when arc push pedal is pushed to feed well and locating slot junction, draw-in groove stops driving lever, the torsion making arc push pedal overcome torsion spring turns to completely towards the locating slot direction of level, and then workpiece is successfully pushed in locating slot, and be positioned on the bottom surface of locating slot.
Closer, in order to avoid workpiece is separated with arc push pedal in propelling movement process, electromagnet (not shown) can be set in arc push pedal, in feed well, arrange a pressure lever type, normally closed travel switch near locating slot one end, the trip switch series is connected on (not shown) in the current supply circuit of electromagnet coil simultaneously.Like this, when the lower end of arc push pedal in feed well, electromagnet coil power produces suction, the workpiece entering feed well can be absorbed and fixed on the propelling movement face of arc push pedal, when arc push pedal is pushed to upper end and locating slot junction, travel switch works and makes magnet spool dead electricity, thus is discharged by workpiece and be positioned in locating slot; During the downward rollback of arc push pedal, electromagnet recovers suction again.Travel switch can be arranged on the upside of feed well and locating slot junction, correspondingly relative with driving lever in arc push pedal upside arranges a compressing tablet (not shown), when arc push pedal is rotated because driving lever is stopped by draw-in groove, the depression bar of compressing tablet pushing travel switch, thus travel switch is opened a way, electromagnet loses suction, and the workpiece be adsorbed in arc push pedal is released, and on the bottom surface of just rotational positioning groove.
As Fig. 1, shown in Fig. 2, it is made to rotate in order to the workpiece of clamping and positioning in locating slot, we can arrange a driving shaft 6 laterally placed in the side of locating slot, driving shaft can by motor by existing belt pulley, the transmission mechanisms such as gear drive, driving shaft and locating slot sidewall perpendicular, and it is coaxial with the bottom surface of locating slot, locating slot then need arrange locating hole 42 in respective drive position on the sidewall near driving shaft, driving shaft head is located in locating hole, and the end face of driving shaft flushes with the inner surface of this sidewall, so that workpiece can successfully enter in locating slot from feed well, and abut on the end face of driving shaft.Certainly, gap must be left between driving shaft and locating hole, so that drive shaft turns.The opposite side of locating slot arranges transversely movable pinch roller seat 7, pinch roller seat is arranged side by side two rotating pinch rollers 71, pinch roller seat can be promoted by cylinder, its moving direction is perpendicular to locating slot sidewall, distance between two pinch rollers and the external diameter of workpiece adapt, so that pinch roller can push down the both sides of workpiece, preferably, in distance between the center of two pinch rollers and workpiece, the mean value of external diameter is equal, thus bistrique mobile space is formed between two pinch rollers, be understandable that, the position of locating slot corresponding pinch roller on the sidewall near pinch roller should arrange pinch roller via hole 43, so that pinch roller can pass pinch roller via hole workpiece pressing.In addition, we also need arrange a bistrique via hole 44 at locating slot on the sidewall of pinch roller, and pinch roller via hole and bistrique via hole are preferably slot.Particularly, bistrique via hole should be arranged on the centre of two pinch roller via holes, like this, bistrique 9 can be made to be positioned at the position, middle of two pinch rollers, namely the bistrique of grinding machine enters in workpiece through bistrique via hole by the control of digital control system, and along moving radially of workpiece the septal fossula of grinding work piece.It should be noted that, the periphery of pinch roller is preferably the cambered surface of evagination, thus makes can form point cantact between pinch roller and workpiece, to make the direction of motion of the contact position of pinch roller and workpiece and speed be consistent, thus avoids relative sliding friction between the two.
Finally, we can also arrange suspended axle 8 in the top near blow tank side in locating slot, suspended axle hangs rotationally a workpiece baffle 81, the lower end of workpiece baffle is unsettled, make it can rotate voluntarily when being subject to External Force Acting, further, workpiece baffle can produce an automatically reset moment under the effect of self gravitation.When workpiece enters locating slot, workpiece baffle can stop workpiece, avoids workpiece directly to tumble in blow tank because of effect of inertia.
The present invention operationally, first workpiece enters in feeding groove, and roll in a sub-material bayonet socket of sub-material rotating disk along feeding groove, now sub-material dial rotation 180 degree, this workpiece is transferred to the feeding groove of sub-material rotating disk opposite side, and automatically enter be adsorbed on arc push pedal in feed well propelling movement face on, follow-up workpiece then enters in another sub-material bayonet socket and prepares.Then workpiece is upwards pushed to and locating slot junction by arc push pedal under the promotion pushing cylinder, due to the effect of draw-in groove, arc push pedal is overturn to be sent in locating slot by workpiece, now arc push pedal makes travel switch action, the power supply of tripping magnet coil, workpiece is released and is positioned on the bottom surface of locating slot, and workpiece end face abuts on the end face of driving shaft coaxially, workpiece baffle then can guarantee that workpiece is reliably located.Then, push cylinder and drive arc push pedal to reset, pinch roller seat is close to locating slot under the promotion of cylinder, two pinch rollers through the pinch roller via hole on locating slot sidewall near workpiece, and by Work-sheet pressing on the end face of driving shaft.Now driving shaft starts high-speed rotation, and rely on frictional force to drive Work piece high-speed to rotate, two then form rolling friction between pinch roller and workpiece, meanwhile, the digital control system of grinding machine controls bistrique and enters in workpiece through bistrique via hole, and along moving radially of workpiece, grinding being carried out to the septal fossula of workpiece, a workpiece to be processed is then sent in feed well by sub-material rotating disk again, and this absorption of workpieces of medical history is in arc push pedal.After completing Deng grinding, driving shaft stops operating, bistrique and pinch roller seat retreat and reset, and push cylinder and again a workpiece to be processed is sent in locating slot, and push manufactured workpiece, it is made to squeeze workpiece baffle, workpiece baffle upwards overturns, the workpiece processed then squeezed turnover hopper also tumbles in the gathering-device be connected with blow tank automatically, workpiece baffle then automatically resets under gravity, the mouth leading to blow tank is closed, avoids the workpiece in locating slot directly to tumble in blow tank.Gathering-device can be simple workpiece collecting box, or a transport tape, and transport tape can connect the blow tank of multiple stage grinding machine, so that by workpiece transfer to stations such as follow-up detection or packagings.Then, pinch roller, bistrique, driving shaft etc. repeat aforesaid action, start the septal fossula of grinding second workpiece.Circulation like this, can carry and grinding septal fossula workpiece quickly and efficiently one by one.You need to add is that, for the ease of controlling the amount of force pushing workpiece baffle open, we also can arrange vertical screw rod 811 near blow tank side in workpiece baffle, leave gap, to be threaded an adjusting nut 812 on screw rod between this screw rod and workpiece baffle.By rotating adjusting nut, can adjust its high and low position on screw rod easily, when adjusting nut rotates, the suspended axle that distance hangs workpiece baffle becomes far away, thus increases the moment of workpiece baffle Self-resetting, makes workpiece not easily squeeze workpiece baffle; Otherwise moment then can be made to reduce, and workpiece is easy to squeeze workpiece baffle.Adjusting nut is adjusted to correct position, both can guarantee that workpiece baffle reliably can stop workpiece, be convenient to workpiece simultaneously and push workpiece baffle open and enter in blow tank.Be understandable that, adjusting nut preferably can adopt two, like this, when adjusting to correct position, can relatively rotate two adjusting nuts, making it mutual compression, to realize self-locking, avoids adjusting nut because of impact shock at screw rod superior displacement.
