Description

Mit der Antriebsvorrichtung, insbesondere kleiner Baustoffpressen, zusammengebauter Kraftmesser Bei Prüfmaschinen mit geringer Kraftäußerung, insbesondere bei kleinen Baustoffpr essen, muß auf die Einfachheit der Kraftmessung und des Antriebes besonderer Wert gelegt werden. Gleichzeitig ist die Forderung zu erfüllen, daß die Kraftanzeige, selbst auf Bauplätzen, wo mit einer Verschmutzung der Maschinen gerechnet werden muß, stets genau ist. Um dies zu erreichen, wurden bisher bereits eingeschliffene Kolben und eingeschliffene Differentialkolben als genaue Meßmittel verwendet.With the drive device, especially small building material presses, Assembled force gauge For testing machines with little force expression, in particular for small building material tests, the simplicity of the force measurement and the drive must be taken into account special value should be placed. At the same time, the requirement must be met that the Force display, even on construction sites where the machines are expected to be contaminated must always be accurate. In order to achieve this, so far have already been ground in Pistons and ground differential pistons used as accurate measuring means.

Nachstehend wird eine neue Ausführung eines Kraftmessers mit eingeschliffenem Differentialkolben beschrieben, bei dem die Antriebsspindel zwecks Druckerzeugung durch den Differentialkolben hindurchgeführt ist.Below is a new version of a dynamometer with a ground Differential piston described in which the drive spindle for the purpose of pressure generation is passed through the differential piston.

In der Abbildung ist der neue Kraftmesser mit dem Antrieb im Schnitt dargestellt.The illustration shows the new dynamometer with the drive in section shown.

Die aufgewendete Prüfkraft-wird hydraulisch an einem Manometer i angezeigt. Die von dem zu prüfenden Körper ausgeübte Gegenkraft )o wirkt auf einen eingeschliffenen Differentialkolben 2, der in dem Zylinder 3 gleitet, welch letzterer durch die Stopfbuchse q. verschlossen wird. Die Gegenkraft P erzeugt also nach Maßgabe der Kolbenquerschnitte eine Flüssigkeitspressung in dem Hohlrauen 5, der einerseits mit dem Manometer i, andererseits mit der Nachfüllvorrichttuig 6 verbunden ist. Mit Hilfe des. Ventils 7 kann die Flüssigkeit im Hohlraum 5 mit dem Füllbehälter 8 in Verbindung gesetzt werden. Durch den Differentialkolben 2, der zweckmäßig mit einer Gewindebüchse 9 ausgestattet ist, tritt eine für den Antrieb dienende Gewindespindel io hindurch. Durch Drehen dieser Spindel mittels des Handrades i i wird die Kraft P ausgeübt, die den Probekörper belastet und zu Bruch bringt. Der Kolben 2 wird durch eine Kappe 12, deren Mitnehmer in entsprechenden Aussparungen des Zylinders 3 leicht gleiten, an der Drehung gehindert.The applied test force is displayed hydraulically on a manometer i. The counterforce exerted by the body to be tested acts on a ground Differential piston 2 sliding in cylinder 3, the latter through the stuffing box q. is closed. The counterforce P is thus generated in accordance with the piston cross-sections a liquid pressure in the hollow roughness 5, which on the one hand with the manometer i, on the other hand is connected to the refill device 6. With the help of the valve 7, the liquid in the cavity 5 can be connected to the filling container 8 will. Through the differential piston 2, which is expediently provided with a threaded bushing 9 is equipped, a threaded spindle serving for the drive passes through. By turning this spindle by means of the handwheel i i, the force P is exerted, which loads the test specimen and breaks it. The piston 2 is covered by a cap 12, the drivers of which slide easily in corresponding recesses in the cylinder 3, prevented from rotating.

Wenn der Kolben 2 durch den Verlust an Flüssigkeit in die Nähe seiner oberen Lage gelangt ist, wird das Ventil 7 geöffnet und damit dem Kolbenantriebsystem Gelegenheit gegeben, wieder in seine unterste Lage zu sinken, indem Meßflüssigkeit aus dem Behälter 8 in den Zylinderraum 5 gesaugt wird.When the piston 2 due to the loss of fluid close to its has reached the upper position, the valve 7 is opened and thus the piston drive system Given the opportunity to sink back into its lowest position by adding measuring fluid is sucked from the container 8 into the cylinder space 5.

Der Vorteil der, beschriebenen Einrichtung liegt vor allem darin, daß infolge ihrer einfachen Vereinigung und besonderen Ausführung die Kraftmeßvorrichtung und der Antrieb zusammen in dem oberen Querhaupt der Prüfmaschine untergebracht werden können.The main advantage of the facility described is that that due to their simple association and special design, the force measuring device and the drive is housed together in the upper crosshead of the testing machine can be.
