Description
Die Erfindung bezieht sich auf einen Positionsgeber zur Anstellhubwegmessung eines, die Lagereinbaustücke von Walzen eines Walzgerüstes beaufschlagenden Hydraulikzylinders, der von einem Führungskolben geführt wird, der sich gegen das Walzgerüst abstützt, bestehend aus einem Teleskopgehäuse, dessen einer, einen Wegaufnehmer aufnehmender, unterer Teil fest mit dem Hydraulikzylinder, und dessen anderer, einen, dem Wegaufnehmer zugeordneten Meßstab aufnehmender oberer Teil gegen den Träger des Führungskolbens abgestützt ist.The invention relates to a position transmitter for measuring the stroke length one that acts on the bearing chocks of rolls of a roll stand Hydraulic cylinder, which is guided by a guide piston that opposes supports the rolling stand, consisting of a telescopic housing, one of which, a lower part receiving a displacement transducer fixed to the hydraulic cylinder, and its other, a measuring rod assigned to the displacement sensor upper part is supported against the carrier of the guide piston.
Positionsgeber dieser Art werden in den Walzgerüsten von Walzenstraßen bei der Banddickenregelung zur Einstellung des Walzspaltes zwischen den Walzen des Walzgerüstes verwendet. Da die Walzspalteinstellung hierbei eine hohe Genauigkeit erfordert, werden nur Positionsgeber verwendet, die mit einer hohen Auflösung arbeiten, und das System muß praktisch spielfrei sein, damit keine Ausschußverluste beim Walzen der Bänder entstehen.Position encoders of this type are used in the roll stands of roller mills at Strip thickness control for setting the roll gap between the rolls of Roll stand used. Because the roll gap setting is highly accurate only position sensors with a high resolution are used work, and the system must be virtually free of play, so that no rejects are lost arise when the strips are rolled.
Bei einer bekannten Ausbildung und Anordnung der Positionsgeber in der Form eines zylindrischen Teleskopgehäuses ist dessen unterer Teil fest mit dem Hydraulikzylinder verbunden, und dessen oberer Teil wird, beaufschlagt durch eine, im unteren Teil angeordnete Feder mit einer, an seiner Stirnseite angeordneten Kugelwölbung gegen ein, an einer am Führungskolben des Hydraulikzylinders befestigten Platte angeordnetes Druckstück gedrückt. In a known design and arrangement of the position encoder in the form The lower part of a cylindrical telescopic housing is fixed to the hydraulic cylinder connected, and the upper part of which is acted upon by a arranged in the lower part with a spring arranged on its end face Ball curvature against one, on one on the guide piston of the hydraulic cylinder attached plate arranged pressure piece pressed.
Der, die Lagereinbaustücke der Walzen des Walzgerüstes beaufschlagende Hydraulikzylinder führt während des Walzbetriebes infolge der dabei bewirkten Biegungen der Walzen über ihre Längsachse innerhalb des Spiels in den Ständern des Walzgerüstes leichte Kippbewegungen aus. Diese Kippbewegungen können unter Umständen auf das empfindliche Bewegungssystem von Meßstab und Wegaufnehmer übertragen werden und führen dann ggf. zu Beschädigungen des Meßstabes oder zu Fehlmessungen.The hydraulic cylinder acting on the bearing chocks of the rolls of the roll stand leads during the rolling operation due to the resulting bends of the reels on their longitudinal axis within the game in the stands of the rolling stand from slight tilting movements. These tilts can possibly on the sensitive movement system of dipstick and Transducers are transmitted and then lead to damage to the Dipstick or for incorrect measurements.
Bei, im Walzbetrieb zeitweise auftretenden hohen Beschleunigungen der Anstellbewegungen des Hydraulikzylinders relativ zum Führungskolben kann es auch vorkommen, daß der obere Teil des Teleskopgehäuses von der, am Führungskolben befestigten Platte nach unten abhebt, d.h., daß sich die Kugelwölbung von dem Druckstück wegbewegt und dadurch Verfälschungen der Meßergebnisse des Positionsgebers verursacht. Eine Verstärkung der im unteren Teil des Teleskopgehäuses angeordneten Feder, deren Kraft diesem Abhebevorgang entgegengerichtet ist, könnte die Verfälschungsgefahr zwar verringern aber nicht ganz beseitigen, würde aber eine zusätzliche Vergrößerung der ohnehin durch die Anwendung dieser Feder schweren und voluminösen Konstruktionen des Teleskopgehäuses erfordern.In the event of high accelerations of the positioning movements that occasionally occur in rolling operation of the hydraulic cylinder relative to the guide piston can also occur that the upper part of the telescopic housing from the, on the guide piston attached plate lifts down, i.e. the spherical curvature of moved the pressure piece and thereby falsifying the measurement results of Position transmitter caused. A reinforcement in the lower part of the telescopic housing arranged spring, the force of which counteracts this lifting process could reduce the risk of adulteration but not completely eliminate it, would be an additional enlargement of the application anyway this spring heavy and voluminous construction of the telescopic housing require.
Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäßen Positionsgeber so zu verbessern, daß neben einer leichteren Bauweise des Teleskopgehäuses aus den zeitweiligen Beschleunigungen des Hydraulikzylinders keine Verfälschungen der Meßergebnisse entstehen können.The invention has for its object the generic position transmitter to improve so that in addition to a lighter design of the telescopic housing no falsifications from the temporary accelerations of the hydraulic cylinder of the measurement results can arise.
Diese Aufgabe wird durch einen, zwischen dem, den Meßstab aufnehmenden oberen Teil des Teleskopgehäuses und der Platte am Führungskolben angeordneten, fest mit diesem verbundenen elastischen Biegestab gelöst, dessen Längsachse in Richtung der Hubbewegung des Hydraulikzylinders verläuft. This task is carried out by a person who holds the dipstick upper part of the telescopic housing and the plate arranged on the guide piston, firmly connected with this elastic bending rod, its longitudinal axis runs in the direction of the lifting movement of the hydraulic cylinder.
Wie die Erfindung weiter vorsieht, können die beiden Enden des Biegestabes, einerseits auf die ihnen zugewandte Oberseite des oberen Teils des Teleskopgehäuses und andererseits auf den Innenboden eines, auf die Platte am Führungskolben aufgesetzten, mit seiner Topföffnung ebenfalls dem Teleskopgehäuse zugeordneten Topfkörpers aufleg- und lösbar mit diesem verbindbar sein. Die Enden des Biegestabes können dabei auch flanschscheibenförmig erweitert ausgebildet sein.As the invention further provides, the two ends of the bending rod, on the one hand on the top of the upper part of the telescope housing facing them and on the other hand on the inside of one, on the plate on the guide piston attached, with its pot opening also assigned to the telescopic housing Pot body can be placed and releasably connected to it. The ends of the bending rod can also be designed to be flanged his.
Da bei dieser erfindungsgemäßen Ausbildungsform eines Positionsgebers der den Meßstab aufnehmende, obere Teil des Teleskopgehäuses über den elastischen Biegestab mit dem Träger des Führungskolbens fest verbunden ist, kann dieser obere Teil auch bei großen Beschleunigungen des Hydraulikzylinders nicht von dem Träger des Führungskolbens abheben und Kippbewegungen des Hydraulikzylinders, z.B. verursacht durch die Walzenbiegungen während des Walzbetriebes, die aufgrund der festen Verbindung des unteren Gehäuseteils mit dem Hydraulikzylinder auf das Teleskopgehäuse übertragen werden, führen lediglich zu einer Ausbiegung des Biegestabes im elastischen Bereich, ohne daß dabei Verfälschungen der Meßergebnisse auftreten können. Gleichzeitig wird die Bauweise des Teleskopgehäuses durch den Wegfall der Feder vereinfacht und fällt weniger schwer aus.Since in this embodiment of a position encoder according to the invention Measuring rod-receiving, upper part of the telescopic housing over the elastic Bending rod is firmly connected to the carrier of the guide piston, this can upper part not at high accelerations of the hydraulic cylinder lift the carrier of the guide piston and tilting movements of the hydraulic cylinder, e.g. caused by the roll bends during the rolling operation, due to the fixed connection of the lower housing part to the hydraulic cylinder transferred to the telescope housing only lead to a bending of the bending rod in the elastic range, without falsification of the measurement results can occur. At the same time, the construction of the telescopic housing is simplified and falls less due to the omission of the spring difficult.
Die Erfindung wird anhand der in der Zeichnung dargestellten Ausführungsbeispiele näher erläutert. In der Zeichnung zeigen
Figur 1- einen in ein Walzgerüst eingebauten Positionsgeber bekannter Ausbildung im Axialschnitt und
Figur 2- den ebenfalls eingebauten Positionsgeber nach der Erfindung, im Axialschnitt.
- Figure 1
- a built-in position transmitter of known training in axial section and
- Figure 2
- the also built-in position transmitter according to the invention, in axial section.
Wie aus Fig. 1 zu ersehen, besteht der Positionsgeber aus einem Teleskopgehäuse,
das sich aus einem rohrförmigen unteren Gehäuseteil 1 und einem, in diesem
axial geführten oberen Gehäuseteil 2 zusammensetzt. Der untere Gehäuseteil 2
ist mittels einer Klemm-Spannvorrichtung 3 fest mit dem Hydraulikzylinder 4 verbunden,
der vertikal auf- und abbeweglich von einem Führungskolben 5 geführt
wird, der verbunden mit einer Platte 6 sich gegen das, nicht dargestellte, Walzgerüst
abstützt. Der obere Gehäuseteil 2 trägt unterhalb seiner Stirnseite eine zentrale
Einspannvorrichtung 7 für den Meßstab 8, der zentralaxial in den, von einer
Zylinderhülse 9 getragenen elektronischen Wegaufnehmer 10 eintaucht. Der obere
Gehäuseteil 2 sitzt mit einem äußeren Ringflansch 2a auf einer Zylinderfeder 11
auf, die gegen ein Bodenstück 1a des unteren Gehäuseteils 1 abgestützt ist. Die
von diesem Bodenstück 1a zu dem Wegaufnehmer geführte Verbindungsleitung
ist mit 12 bezeichnet. Die, nach oben weisende Stirnseite des oberen Gehäuseteils
2 des Teleskopgehäuses trägt eine Kugelwölbung 13, die ein Druckstück 14
beaufschlagt, das an der Unterwand der Platte 6 befestigt ist. Den oberen Gehäuseteil
2 und den unteren Gehäuseteil 1 umschließt ein flexibles Harmonika-Schutzrohr
15, das einerseits am Umfang des unteren Gehäuseteils 1 und andererseits
an dem Druckstück 14 befestigt ist. Der obere Gehäuseteil 2 wird durch
Beaufschlagung seines Ringflansches 2a durch die Zylinderfeder 11 in Richtung
nach oben gegen die Platte 6 gedrückt und stößt damit mit der Kugelwölbung 13
in das Druckstück 14.As can be seen from Fig. 1, the position transmitter consists of a telescopic housing,
which consists of a tubular
Der untere Gehäuseteil 1 des Teleskopgehäuses folgt den Anstellbewegungen
des Hydraulikzylinders 4 in Richtung des dargestellten Doppelpfeils S, da er fest
mit diesem verbunden ist. Dabei bleibt die Andruckverbindung des oberen Gehäuseteils
2 mit der Platte 6 über die Kugelwölbung 13 und das Druckstück 14 bestehen,
weil der obere Gehäuseteil 2 unter dem Druck der Zylinderfeder 11 steht. Nur
bei einer sehr schnell beschleunigten Bewegung des Hydraulikzylinders 4 nach
unten kann sich die Andruckverbindung zwischen Kugelwölbung 13 und Druckstück
14 lösen, wenn der Druck der Zylinderfeder 11 nicht ausreicht, diese Andruckverbindung
aufrechtzuerhalten. In diesem Fall entspricht die Position des
Meßstabes 8 im Wegaufnehmer 10 nicht mehr der tatsächlichen Position des Führungskolbens
5 mit der Folge, daß unrichtige Meßergebnisse weitergeleitet werden.The
Die Ausbildung nach Fig. 2 entspricht der nach Fig. 1 mit Bezug auf die feste Verbindung
des unteren Gehäuseteils 21 des Teleskopgehäuses mit dem Hydraulikzylinder
4 und der Führung des oberen Gehäuseteils 22 in diesem Teleskopgehäuse
mit der Maßgabe, daß wegen des Wegfalls der dort verwendeten Zylinderfeder
11 nur die, der Zylinderhülse 9 entsprechende Zylinderhülse 29, die auch
hier den Wegaufnehmer 20 erfaßt und trägt, als Führungselement für den, sie
umfassenden und auf ihr gleitenden oberen Gehäuseteil 22 dient, mit der Folge,
daß weniger und leichtere Bauteile verwendet werden können. Anstelle der Kugelwölbung-Druckstück-Verbindung
13, 14 bei der Ausbildung nach Fig. 1 ist auf
die Platte 6 ein Topfkörper 23, mit seiner Topföffnung nach unten gerichtet, über
eine Ausnehmung 6a im Träger 6 aufgesetzt und befestigt. Ein an beiden Enden
24a, 24b flanschscheibenförmig erweiterter elastischer Biegestab 24 ist mit diesen
Enden einerseits am Innenboden des Topfkörpers 23 und andererseits an der äußeren
Stirnfläche des oberen Gehäuseteils 22 befestigt. Der untere Gehäuseteil
21 und ein unterer Abschnitt des oberen Gehäuseteils 22 werden von dem Harmonika-Schutzrohr
25 umschlossen, und der, in die zentrale Einspannvorrichtung
27 eingesetzte Meßstab 28 taucht in den Wegaufnehmer 20 ein.2 corresponds to that of FIG. 1 with reference to the fixed connection
of the
Wie ersichtlich, besteht bei dieser Ausbildungsform des Positionsgebers eine feste
Verbindung zwischen dem oberen Gehäuseteil 22 des Teleskopgehäuses, das
den Meßstab 28 trägt und der Platte 6 mit der Folge, daß auch bei einer beschleunigten
Anstellbewegung des Hydraulikzylinders 4 in Richtung des Doppelpfeils
S nach unten kein Abriß dieser Verbindung erfolgen kann. Kippbewegungen
des Hydraulikzylinders 4, z.B. verursacht durch die Walzenbiegungen während
des Walzbetriebes, die aufgrund der festen Verbindung des unteren Gehäuseteils
21 mit dem Hydraulikzylinder 4 auf das ganze Teleskopgehäuse übertragen werden,
führen lediglich zu einer Ausbiegung des Biegestabes 24 im elastischen Bereich,
ohne daß dabei Verfälschungen der Meßergebnisse auftreten können. As can be seen, there is a fixed position in this form of training of the position giver
