KLASS INTERNATIONELLSVENSK F. 06 h47h: PATENT- AND REGISTRRINGSVERKET Ans. 11 596/1962 was received on 29/10 1962 issued on 16/12 1963 BS OLSSON, JOHANNESHOV Device for fiddling with stepwise rotational movement The present invention relates to such a device for effecting stepwise rotational movements, for example for opening or forcing spindles, with a toothed wheel, two feed rafters, one intended for driving the toothed wheel in the clockwise direction of rotation and the other for the wheel driving in the counterclockwise direction of rotation, and a pressure medium-actuated servomotor with a reciprocating and constantly acting piston rod for the feed rafters.

Uppfinningen kannetecknas huvudsakligen darav, att matarsparrarna oeh kolvstangen aro anordnade installbara relativt varandra i en sadan mot kolvstangens arbetsrorelseriktning huvudsakligen tvargaende riktning, aft kolystangen for val av rotationsrikining kan bringas att paverka antingen den ena eller den andra matarsparren och i valbar punkt pa respektive matarsparr for reglering av matningsritelsens langd. The invention can be characterized mainly in that the feed rafters and the piston rod are arranged installable relative to each other in such a direction substantially opposite to the working direction of the piston rod, since the coal rod for selecting the direction of rotation can be caused to affect either one or the other feed raft. of the length of the feeding ritual.

Vid anordningar av fOreliggande slag har man stallt upp onskemalet, att man med en och samma servomotor dels skall kunna driva matarsparrarna for det tandade hjulets drivning i bade meclurs och moturs rotationsriktning och dels kunna ge den paverkade matarsparren forhojt startmoment. In devices of the present type, the wish has been set up that with one and the same servomotor it should be possible to drive the feed chucks for the drive of the toothed wheel in both the direction of rotation and counterclockwise rotation and to give the actuated feed chute increased starting torque.

Vid kanda anordningar fOr att oppna och stanga spindelforsedda ventiler har man anvant sig av en av en sarskild servomotor paverkad matarsparr ,for det tandade hj ule ts -vridning i en riktning och áv en av en annau servomotor. paverkad matarsparr for hjulets drivning I motsatt riktning, vilket fordyrat anlaggningen. Vid de kanda anordningarna har man icke heller lyckats Visa problemet med att med en och samma servomotor ge en matarsparr ett fOrhojt startmoment. Delta senare är mycket viktigt, eftersom vridmomentet, som erfordras for stangning av en ventil ár otillracklig for oppning av densamma. Nar man darvid Oxen har att taga hansyn till dels vaxelventiler och dels att de fiesta, ventiler Dupl. kl. 47 g: 45/04 med stigande spindel numera tillverkas med en vertikaltatning i spindelgenomgangen bOr ants& den ideala ,motorn for detta andamal kunna utveckla ett i forhallande till de erforderliga tilldragningsmomenten med lampligt varde ,forhojt startmoment i bada rotationsriktningarna. In known devices for opening and closing spindle-fitted valves, a feed ratchet actuated by a special servomotor has been used, for the toothed wheel rotation in one direction and one by another servomotor. affected feed ratchet for wheel drive In the opposite direction, which made the system more expensive. With the known devices, it has also not been possible to show the problem of using a single servo motor to give a feed chute an increased starting torque. Delta later is very important, because the torque required for closing a valve is insufficient for opening it. When you have the Taurus to take his view partly to the gear valves and partly to the fiesta, Dupl valves. at 47 g: 45/04 with rising spindle is now manufactured with a vertical inclination in the spindle passage should be assumed & the ideal, the motor for this purpose can develop a in relation to the required tightening torques with suitable value, increased starting torque in both directions of rotation.

Medelst foreliggande uppfinning vinner man .dels fordelen av att med en och samma servomotor karma paverka antingen den matarsparr, som ger det tandade hjulet en medurs rotationsriktning, eller den matarsparr, som ger det tandade hjulet en moturs rotationsriktning, och dels fordelen av att erhalla ett f8rhojt startmoment i hada rotationsriktningarna. By means of the present invention, one gains the advantage of having with one and the same servomotor karma actuating either the feed ratchet which gives the toothed wheel a clockwise direction of rotation, or the feed ratchet which gives the toothed wheel a counterclockwise direction of rotation, and partly the advantage of obtaining a increased starting torque in the direction of rotation.

Uppfinningen skall har narmare beskrivas I anslutning till bifogade ritning, som vicar anordningen i princip sedd uppifran tried locket borttaget . The invention will be described in more detail in connection with the accompanying drawing, which shows the device in principle seen from above with the lid removed.

Anordningen bestar av ett ladliknande holj e med ett lock. I holjets botten ar vridbart lag-rat ett tandat hjul 4, vid vilket ventilspindeln ãr fast. Mellan det tandade bjulet °eh botten ar vridbart lagrad en cirkular konsol t, som vid ett parti av periferin nar utanfor det tandade hjulet 4 och bildar faste for tva bredvid varandra vridbart lagrade matarsparrar 1 och 2. Dessa aro anordnade att vid vridning Tiring fastpunkterna i konsolen rOra sig mot och fran det tandade hjulet. Den ena matarsparren 1 är sa fast, att den, liar den rot- sig mot Oct tandade hjulet, wider detta i medurs rotationsriktning, naedan den andra matarsparren 2 är sa fast, att den, nar den ror sig mot det tandade hjulet, paverkar detta att rora sig i moturs rotationsriktning. The device consists of a charge-like housing e with a lid. A toothed wheel 4 is rotatably mounted in the bottom of the housing, to which the valve stem is fixed. Between the toothed wheel and the bottom a rotatable bracket is rotatably mounted, which at a portion of the periphery extends outside the toothed wheel 4 and forms fasteners for two adjacent rotatably mounted feed rafters 1 and 2. These are arranged to rotate the fixed points in rotation. the console moves towards and away from the toothed wheel. One feed ratchet 1 is so fixed that when it rotates towards the Oct toothed wheel, it widens in the clockwise direction of rotation, since the other feed ratchet 2 is so fixed that when it moves towards the toothed wheel, it affects this to move in the counterclockwise direction of rotation.

Matarsparrarna 1 och 2 hMlas med fjaderkraft tryckta ifran det tandade hjulet 4 och deras fran detta vanda andar aro utformade med ,utstrackt anslagsyta, sa att man genom att trycka pa anslagsytorna i olikbelagna punkter i forhallande till matarsparrarnas vridningsaxlar erhaller olika langa matningsrorelser mot det tandade hjulet 4. 2— — Konsolen & ar kopplad till en vid h&j et fast manOvercylinder 7, rnedelst vilken konsolen kan paverkas att vrida sig. Konsolen har pa det cirkulara partiet forsetts rued en stoppklack 8, mot vilken en med hakar i andarna forsedd tvaarmad havstang 9 är avsedd att anligga med den ena eller den andra andhaken. Den hakforsedda havstangen tjanstgor salunda som sparr for konsolens vridning och installning. The feed rafters 1 and 2 are spring-loaded by means of the toothed wheel 4 and their spirits from this are designed with an extended abutment surface, so that by pressing the abutment surfaces at different points in relation to the axes of rotation of the feed rafters different length feed movements towards the toothed wheel are obtained. 4. 2— - The bracket is coupled to a wide-mounted maneuvering cylinder 7, under which the bracket can be caused to rotate. On the circular part, the bracket is mounted on a stop lug 8, against which a heated sea rod 9 provided with hooks in the spirits is intended to abut with one or the other hook hook. The hook-mounted sea rod thus serves as a barrier for the console's rotation and installation.

Vid holjets sida i lige mitt for fastena for matarsparrarna 1 och 2 ph konsolen 6 ãr en tryckmediumpaverkad servomotor 5 med en fram- och atergaende kolvstang 3 fast. Servomotorns kolvstang nar ett stycke in i hOlj et och kan paverka den ena eller den andra matarspirren och olika punkter pa. resp. matarsparr. Vid ett arbetsslag hos servomotorn paverkar saledes kolvstangen nagon av matarsparrarna att Ora en frammatningsrorelse. Kolvstangen 3 har konstant slaglangd. At the side of the housing, just in the middle of the fasteners for the feed rafters 1 and 2 ph the bracket 6, a pressure medium-actuated servomotor 5 with a reciprocating piston rod 3 is fixed. The piston rod of the servomotor reaches a distance into the housing and can affect one or the other feed sprocket and different points on it. resp. matarsparr. During a working stroke of the servomotor, the piston rod thus affects one of the feed ratchets to cause a feed movement. The piston rod 3 has a constant stroke.

Anordningen fungerar pa fSlj ande satt. Vid start av servomotorn 5 ges samtidigt impuls till manovercylindern 7, vilken paverkar konsolen 6 att vrida sig. Den som sparr for konsolens 6 vridning tjanande tvaarmade hakforsedda havarmen 9 erhaller via paverkan fran det tandade hjulets 4 rotationseentrum impuls att intaga ett visst bestamt sparrlage for stoppklacken 8 pa konsolen G. Konsolen vrider sig da till ett lage, som bestimmes av sparren 9, och matarsparrarna 1 och 2 forflytta sig relativt kolvstangens 3 ande till den punkt ph en av matarsparrarna, som ger minsta frammatningsrorelsen. Matarsparren har da intagit sadant lage mitt f5r kolvstangen 3, att denna vid sin roreIse framat paverkar den aktuella matarsparrens anslagsyta pa. langsta avstand frau matarsparrens vridningsaxel. The device works as follows. At the start of the servomotor 5, impulse is simultaneously given to the control cylinder 7, which causes the bracket 6 to turn. The one which locks for the rotation of the bracket 6 serving the arm-mounted hook-mounted lever 9 receives, by the action of the center of rotation of the toothed wheel 4, an impulse to assume a certain specific locking layer for the stop lug 8 on the bracket G. The bracket then turns into a position the feed rafters 1 and 2 move relative to the spirit of the piston rod 3 to the point ph one of the feed rafters which gives the least feed movement. The feed chuck has then assumed such a position in the middle of the piston rod 3 that this, when it moves forward, affects the abutment surface of the chuck in question. longest distance from the axis of rotation of the feed chuck.

Matarsparrarnas 1 och 2 utformning ãr lampligen sadan, att de i detta lige mata fram det tandade hjulet 4 tva. tander. The design of the feed rafters 1 and 2 is suitably such that in this straight line they feed the toothed wheel 4 two. tander.

Sedan servomotorn 5 med kolvstangen 3 gjort nagra arbetsslag paverkar manovercylindern 7 konsolen 6 att vrida sig till ett lage, dar kolvstangens ande paverkar matarsparren i en punkt belagen narrmare matarsparrens vridningsaxel. Matarsparrens frammatningsrorelse blir d5. langre och det tandade hjulet 4 matas fram tre Under. After the servomotor 5 with the piston rod 3 has made some working strokes, the actuating cylinder 7 causes the bracket 6 to turn to a position, where the spirit of the piston rod acts on the feed chuck in a point-mounted jig. The feed movement of the feed spar becomes d5. longer and the toothed wheel 4 is fed three Under.

Harvid har automatiskt sparren 9 for stoppklacken 8 paverkats att intaga sa.dant lage, att denna omstallning av konsolen 6 tillates. In this case, the latch 9 for the stop lug 8 has automatically been caused to assume such a position that this adjustment of the bracket 6 is permitted.

Uppfinningen är icke begransad till den har visade utforingsformen, utan den kan betraffande detaljernas.utformning varieras rent konstruktivt. The invention is not limited to the embodiment shown, but it can be varied purely constructively with regard to the design of the details.
