Abstract

In a parallel vice, a plastic body (10) is inserted with prestress into a recess (11) in the housing (1) located above the rail (6) belonging to the movable jaw (7). The plastic body (10) has the form of a prism, the base of which is limited by two essentially parallel arcs (12, 13) which are connected at each of their ends by two straight lines (14, 15) arranged approximately at right angles. Two of these straight lines (15) are essentially in line with one another. By means of the longitudinal faces belonging to these straight lines (15), the plastic body (10) forming a spring bears with prestress against the top side (9) of the rail (6), in order to prevent any play between the rail (6) and housing (1). <IMAGE>

Description

Die Erfindung betrifft einen Parallelschraubstock mit einer Einrichtung zum Vermeiden von Spiel zwischen der zur bewegenden Backe gehörenden Schiene und dem Gehäuse.The invention relates to a parallel vice with a device for avoiding play between the rail belonging to the moving jaw and the housing.

Bei einem bekanntgewordenen Parallelschraubstock war die Schiene an ihrer Oberseite anstelle der beiden Längskanten mit Schrägflächen versehen, mit welchen je zwei zu diesen Flächen senkrecht stehende, in Gewindebohrungen des Gehäuses eingedrehte und mit Kontermuttern fixierbare Schrauben zusammenwirkten.In a parallel vise that became known, the rail was provided on its top instead of the two longitudinal edges with inclined surfaces with which two screws perpendicular to these surfaces, screwed into threaded bores in the housing and fixable with lock nuts, interacted.

Zweck dieser Ausbildung war es, eine Feineinstellung des Spiels zwischen Schiene und Gehäuse möglich zu machen.The purpose of this training was to make it possible to fine-tune the play between the rail and the housing.

Nachteilig bei diesem Schraubstock war der Umstand, daß zum Einstellen des Spiels vier Schrauben betätigt und fixiert werden mußten; eine mühevolle, umständliche und zeitraubende Tätigkeit.A disadvantage of this vise was the fact that four screws had to be operated and fixed in order to set the game; an arduous, cumbersome and time consuming Activity.

Eine ähnliche Ausführung eines Schraubstockes wird in der AT-PS 309 355 beschrieben. Dort hat die Schiene an ihrer Oberseite anstelle der beiden Längskanten zwei Abfasungen, deren eine sich gegen eine entsprechende Schrägfläche des Kanals im Schraubstockfluß legt und deren andere von zwei federnden Stöpseln mit entsprechend geneigten Endflächen belastet wird, die in quer zur Schiene nahe deren Oberfläche verlaufende Bohrungen eingesetzt und darin durch Gewindestopfen in ihrer Lage gehalten sind.A similar version of a vice is described in AT-PS 309 355. There the rail has two chamfers on its top instead of the two longitudinal edges, one of which lies against a corresponding inclined surface of the channel in the vise flow and the other of which is loaded by two resilient plugs with correspondingly inclined end faces, which run in holes running transversely to the rail near the surface of the latter used and held in place by threaded plugs.

Eine andere Möglichkeit zum Einstellen bzw. Vermeiden des Spiels lag in der Anordnung eines Keils aus Stahl, der in eine zur Schiene offene, oberhalb derselben im Gehäuse vorgesehene Vertiefung mit dem Keilwinkel entsprechend geneigt verlaufender Bodenfläche eingelegt war. Mittels zweier Schrauben konnte der Keil in der Vertiefung verschoben und gegen die Oberseite der Schiene gedrückt werden. Durch zwei entgegengesetzt wirkende Schrauben wirde der Keil in seiner richtigen Lage fixiert.Another possibility for adjusting or avoiding the play lay in the arrangement of a wedge made of steel, which was inserted into a recess open to the rail and provided above the same in the housing with the wedge angle correspondingly inclined bottom surface. The wedge could be moved in the recess by means of two screws and pressed against the top of the rail. The wedge is fixed in its correct position by two counter-acting screws.

Die Berührungsfläche zwischen Keil und Schiene war wohl größer als bei Anordnung der vier Schrauben bzw. der zwei Stöpsel gemäß der AT-PS 309 355 allein, sodaß eine geringere Abnützung und damit eine längere Betriebsdauer ohne Nachstellung zu erwarten war; die Einstellarbeit war aber genauso mühevoll wie beim älteren Stand der TechnikThe contact area between the wedge and the rail was probably larger than with the arrangement of the four screws or the two plugs according to AT-PS 309 355 alone, so that less wear and thus a longer operating time without adjustment was to be expected; the adjustment work was just as difficult as with the older state of the art

Aufgabe der Erfindung ist es, die Einstellarbeit zu vermeiden und jede Abnützung an der Schiene zu verhindern.The object of the invention is to avoid the adjustment work and to prevent any wear on the rail.

Zum Erreichen dieses Ziels wird vorgeschlagen, bei einem Schraubstock der eingangs angegebenen Art erfindungsgemäß zwischen dem Gehäuse und der zur bewegbaren Backe gehörenden Schiene einen unter Vorspannung stehenden Kunststoffkörper od.dgl. vorzusehen.To achieve this goal, it is proposed, according to the invention, for a vice of the type specified at the outset between the housing and the part belonging to the movable jaw Rail or the like a pre-stressed plastic body. to provide.

Further features of the invention are explained below with reference to the drawing, which illustrates an embodiment of the vice according to the invention. Hiebei is
  • 1 is a view, partly in section,
  • Fig. 2 is a section along the line II-II in Fig. 1,

Der gezeigte Schraubstock besteht aus dem Gehäuse 1, welches einstückig ist mit der festen Backe 2, aus dem Amboß 3 und der Grundplatte 4. In dem zwischen dem Amboß 3 und der Grundplatte 4 befindlichen Gehäuseabschnitt ist ein Kanal 5 zur Aufnahme und Führung der Schiene 6 vorgesehen, die mit der bewegbaren Backe 7 ein Ganzes bildet.The vice shown consists of the housing 1, which is integral with the fixed jaw 2, the anvil 3 and the base plate 4. In the housing section between the anvil 3 and the base plate 4 there is a channel 5 for receiving and guiding the rail 6 provided that forms a whole with the movable jaw 7.

Die Schiene 6 hat im wesentlichen verkehrt-U-förmigen Querschnitt und nimmt den Gewindeteil der Spindel 8 sowie auch die mit dem Gehäuse einstückige (nicht dargestellte) Spindelmutter auf. Die Spindel 8 und die Schiene 6 samt Backe 7 können in einfachster Weise vom Gehäuse 1 getrennt werden.The rail 6 has a substantially inverted U-shaped cross section and takes up the threaded part of the spindle 8 and also the spindle nut (not shown) which is integral with the housing. The spindle 8 and the rail 6 together with the jaw 7 can be separated from the housing 1 in the simplest way.

Die Schiene 6 und damit die bewegbare Backe 7 ist an den Seitenflächen des Kanals 5 und an dessen Bodenfläche geführt. Zur Führung der Oberseite 9 der Schiene 6 ist ein Kunststoffkörper 10 vorgesehen, der von oben her unter Vorspannung an der Schiene 6 anliegt. Dieser Kunststoffkörper 10 ist in eine nach unten zur Schiene 6 hin offene Ausnehmung oder Vertiefung 11 im Gehäuse 1 eingelegt. Diese Vertiefung ist von Wänden begrenzt, die im wesentlichen parallel bzw. senkrecht zur Oberseite 9 der Schiene 6 verlaufen.The rail 6 and thus the movable jaw 7 is guided on the side surfaces of the channel 5 and on its bottom surface. To guide the upper side 9 of the rail 6, a plastic body 10 is provided, which bears against the rail 6 from above under prestress. This plastic body 10 is inserted into a recess or recess 11 in the housing 1 which is open towards the bottom of the rail 6. This depression is delimited by walls which run essentially parallel or perpendicular to the top 9 of the rail 6.

Der in Fig. 3,4 und 5 größer dargestellte Kunststoffkörper 10 hat die Form eines Prismas, dessen Querschnitt von zwei im wesentlichen zueinander parallelen (konzentrischen) Bögen 12,13 begrenzt wird, die an ihren Enden durch jeweils zwei Gerade 14, 15 verbunden sind, welche miteinander im wesentlichen einen rechten Winkel einschließen, wobei darunter ein Winkel von 83 bis 107° verstanden wird. Die Geraden 15 fluchten miteinander, wie in Fig. 5 gezeigt ist, wodurch die durch die Geraden 15 entstehenden Gleitflächen sowohl eine leichte Auf-Zu-Bewegung der Schiene 6 (möglichst geringe Flächenpressung) als auch eine durch die Vorspannung gegebene Nachstellung des Schienenspiels bei eventuellem Verschleiß der Gleitfläche ermöglichen. An der einen Stirnseite 16 kann eine Abschrägung 17 vorgesehen sein, welche das Einschieben der Schiene 6 in den Kanal 5 erleichtert, wobei der Kunststoffkörper 10 von der Hinterseite des Gehäuses 1 etwa mit einem Schraubenzieher, einem Drahtstück od.dgl. in der Ausnehmung 11 gehalten wird. Die andere Stirnseite 18 kann etwas schräg verlaufen.The plastic body 10 shown larger in FIGS. 3, 4 and 5 has the shape of a prism, the cross section of which is delimited by two essentially parallel (concentric) arcs 12, 13, which are connected at their ends by two straight lines 14, 15 which essentially enclose a right angle with one another, whereby this is understood to mean an angle of 83 to 107 °. The straight lines 15 are aligned with one another, as is shown in FIG. 5, as a result of which the sliding surfaces created by the straight lines 15 result in both a slight open-close movement of the rail 6 (as little surface pressure as possible) and also an adjustment of the rail play given by the pretensioning if necessary Allow wear of the sliding surface. On one end 16, a bevel 17 can be provided, which facilitates the insertion of the rail 6 into the channel 5, the plastic body 10 or the like from the rear of the housing 1 using a screwdriver, a piece of wire or the like. is held in the recess 11. The other end face 18 can run somewhat obliquely.

Die Höhe H des Kunststoffkörpers ist in dessen unbelastetem Zustand größer als die Tiefe t der Ausnehmung oder Vertiefung 11 im Gehäuse 1.In its unloaded state, the height H of the plastic body is greater than the depth t of the recess or depression 11 in the housing 1.

Der Kunststoffkörper 10 kann beispielsweise aus "Hostaform", "Delrin 500" oder ähnlichen hochelastischen, abriebfesten Kunststoffen bestehen.The plastic body 10 can for example consist of "Hostaform", "Delrin 500" or similar highly elastic, abrasion-resistant plastics.

Anstelle der Bögen 12,13 können auch Polygonzüge (Folgen von geraden Linien) oder Bögen und Gerade usw. verwendet sein.Instead of the arcs 12, 13, polygons (sequences of straight lines) or arcs and straight lines etc. can also be used.

Im eingebauten Zustand liegt der Kunststoffkörper 10 mit den an den Geraden 15 entsprechenden Längsflächen an der Oberseite 9 der Schiene 6 mit Vorspannung an, da seine Höhe im unbelasteten Zustand größer ist als die Tiefe der Ausnehmung 11. Dadurch wird jegliches Spiel zwischen Schiene 6 und Kanal 5 vermieden. Die Lebensdauer des Kunststoffkörpers 10 ist sehr hoch, denn einerseits ist der Kunststoff, aus welchem der Körper besteht, an sich abriebfest, und anderseits ist ein Verschleiß der Oberseite der Schiene 6 nicht zu erwarten, weil der Kunststoff wesentlich weicher ist als der Stahl der Schiene.In the installed state, the plastic body 10 lies with the longitudinal surfaces corresponding to the straight lines 15 on the upper side 9 of the rail 6 with prestress, since its height in the unloaded state is greater than the depth of the recess 11. This eliminates any play between the rail 6 and the channel 5 avoided. The service life of the plastic body 10 is very long, because on the one hand the plastic from which the body is made is inherently resistant to abrasion, and on the other hand wear of the upper side of the rail 6 is not to be expected because the plastic is considerably softer than the steel of the rail .

Bei der in Fig. 6 gezeigten Ausführungsform sind die Geraden 15ʹ um einen Winkel α schräg nach innen zur Waagrechten geneigt. Der Winkel α beträgt 3 bis 7°, vorzugsweise 5°. Hiedurch wird erreicht, daß die durch die Geraden 15ʹ entstehenden Gleitflächen im vorgespannten Zustand satt an der Schiene 6 aufliegen, wodurch ein Minimum an Flächenpressung resultiert.In the embodiment shown in Fig. 6, the straight lines 15ʹ are inclined at an angle α obliquely inwards to the horizontal. The angle α is 3 to 7 °, preferably 5 °. This ensures that the sliding surfaces created by the straight lines 15ʹ lie snugly against the rail 6 in the prestressed state, which results in a minimum of surface pressure.
