Description

Vorrichtung zur Härtebestimmung durch- Erzeugung eines Kugeleindrucks. Die Erfindung bezweckt die Verbesserung der Vorrichtungen zur Härtebestimmung durch' Erzeugung von Kugeleindrücken, bei denen eine Preßvorrichtung und ein Druckkraftmesser mit einem gemeinsamen Träger zu einer handlichen und leicht tragbaren Einrichtung vereinigt sind.Device for hardness determination by generating a spherical impression. The invention aims to improve the devices for hardness determination by ' Generation of ball indentations, in which a pressing device and a pressure force meter with a common carrier to a handy and easily portable device are united.

Die Erfindung besteht darin, daß der Träger der Preßvorrichtung und des Druckkraft-. messers als ein aus einem Stück bestehender geschlossener Rahmen ausgebildet ist, innerhalb dessen auch der Druckkraftmesser befestigt ist. ' Hierdurch wird es möglich, dem Träger der Preßvorrichtung und des Druckkraftmessers einen erheblich kleineren Querschnitt zu geben, als er bei den bekannten Apparateg der genannten Art vorhanden sein muß, so, daß die ganze Vorrichtung ein geringes Gewicht erhält und deshalb für ihren Zweck besonders brauchbar ist. Auch wird dex Druckkraftmesser durch den geschlossenen Rahmen besser als bei den bekannten Vorrichtungen gegen Beschädigungen geschützt.The invention consists in that the carrier of the pressing device and of the compressive force. knife as a one-piece closed frame is formed, within which the pressure dynamometer is also attached. 'Through this it becomes possible to the carrier of the pressing device and the pressure force meter one to give considerably smaller cross-section than with the known apparatus of the mentioned type must be available so that the entire device is light in weight and is therefore particularly useful for its purpose. There is also a dex pressure dynamometer by the closed frame better than with the known devices against Damage protected.

Die Zeichnung stellt eine der Erfindung genllß ausgebildete Kugeldruckpresse in einem Ausführungsbeispiel in perspektivischer Ansicht dar.The drawing represents a ball pressure press designed according to the invention in one embodiment in a perspective view.

An der einen Innenseite des Rahmens a ist der Druckkraftmesser b befestigt, mit welchem die Druckkugel c auswechselbar verbunden ist. Der Druckkraftmesser ist in eine schwalbenschwanzförmige Nut an dem Rahmen a eingesetzt. An der dem Druckkraftmesser 1b gegenüberliegenden Seite des Rahmens #a ist eine Schraubenspindel gelagert, welche durch einen knebelbolzen e gedreht wird. Die Sehraubenspindel;il wirkt auf eine Druckplattet, welche durch prismatische Schienen g geführt wird.The pressure dynamometer b is attached to the inside of the frame a, with which the pressure ball c is interchangeably connected. The compression dynamometer is inserted into a dovetail groove on the frame a. On the pressure force meter 1b opposite side of the frame #a is mounted a screw spindle, which is rotated by a toggle bolt e. The very spindle; il acts on one Pressure plate, which is guided by prismatic rails g.

Bei Ausführung des Versuchs wird der zu prüfende Körper zwischen die Druckplatte/ und die Kugele des Kraftmessers b gebracht und in ihm durch Anziehen der Schraubenspindel d ein Kugeleindruck erzeugt.When the test is carried out, the body to be tested is placed between the Pressure plate / and the balls of the dynamometer b brought and tightened in it the screw spindle d creates a spherical impression.

Wenn besonders große Probestücke zu prüfen sind, so kann der Kraftmesser b aus dem Rahmen a herausgenommen und in Verbindung mit einer beliebigen Spannvorrichtung benutzt werden.If particularly large specimens are to be tested, the dynamometer can b taken out of the frame a and in connection with any clamping device to be used.
