Description

mittels eines Diamanten wirkende Abrichtvorrichtung für Schleifscheiben an Ort und Stelle. Die Erfindung betrifft eine mittels eines, Diamanten wirkende Abrichtvörrichtung für Schleifscheiben an Ort und Stelle mit an einem schwenkbaren Arm angebrachten Diamanthalter. Die Neuerung besteht im wesentlichen darin, daß der Lagerbock für die Welle des Diamanthalters auf dem Schleifspindel-Bock und sowohl die Schwenkwelle zur Führung des Diamanten längs der ebenen abgerichteten Schleiffläche als auch der Diamanthalterschaft zwecks Einstellung lotrecht dazu parallel zur Spindelachse verlaufen, so daß unabhängig von der jeweiligen Lage der Spindel die ebene Abrichtung durch bloßes Schwingen des Armes mittels einer beliebigen Schwenkvorrichtung erfolgen kann. Die Einrichtung wird zweckmäßig so getroffen, daß die Welle des Diamanthalterarmes mittels einer Schraubenfeder o. dgl. achsial bis zur Anlage ihres Bundes an die Lagerbüchse zwecks Beseitigung des Abnutzungsspielraumes vorgeschoben wird.Dressing device for grinding wheels that works by means of a diamond in place. The invention relates to a diamond acting by means of a Dressing device for grinding wheels on the spot with a swivel Arm mounted diamond holder. The innovation is essentially that the bearing block for the shaft of the diamond holder on the grinding spindle block and both the pivot shaft for guiding the diamond along the flat, dressed grinding surface as well as the diamond holder shaft for the purpose of adjustment perpendicular to it, parallel to the spindle axis run so that the planar dressing regardless of the respective position of the spindle be done by simply swinging the arm by means of any swivel device can. The device is expediently made so that the shaft of the diamond holder arm by means of a helical spring o Bearing bush is advanced for the purpose of eliminating the wear clearance.

Ein Ausführungsbeispiel der Vorrichtung ist in Abb. r in Ansicht dargestellt. Abb. a und 3 zeigen in größerem Maßstabe einen Längsschnitt durch die Abrichtvorrichtung, sowie eine Rückansicht derselben.An embodiment of the device is shown in Fig. R in a view. Figs. A and 3 show, on a larger scale, a longitudinal section through the dressing device, as well as a rear view of the same.

Der zum Abrichten der Schleifscheibe A dienende Diamant 228a ragt aus dem äußeren Ende einer Hülse 229 heraus und wird in der Hülse auf bekannte Weise durch einen Bolzen 23o gehalten, der andererseits mit der Hülse durch Gewinde schraubbar verbunden ist. Die Hülse 229 ist in einer Bohrung 231 eines mit einer Welle 233 aus einem Stück bestehenden Armes 232 gelagert. Die Welle 233 ist in einem Lager 234 eines durch Schrauben 235 an der Lagerhülse 23b der Schleifscheibenspindel befestigten Ständers 234' drehbar angeordnet. Die Hülse 229 wird durch eine geeignete Spannschraube 235' in der Bohrung 231 festgehalten. Die Welle 233 trägt auf ihrem abgesetzten Teil 236 eine einseitig als Schneckenrad 238 ausgebildete Büchse 237. Mit dem Schneckenrad 238 steht eine auf Welle 24o befestigte Schnecke 239 in Eingriff. Die im Ständer 234' gelagerte Welle 240 trägt eine Handkurbel 241, durch deren Drehung die Welle 233 ihren Arm 232 aus der Ruhe- in Arbeitsstellung zur ebenen Oberfläche der Schleifscheibe A schwingt (Abb. i). Das Gehäuse 49a ist an dieser Stelle mit einem Ausschnitt 242 versehen, um den Diamanten durchtreten zu lassen. Auf -das äußere Ende der Welle 233 ist eine Mutter aufgeschraubt, zwischen welcher und der Büchse 237 eine Schraubenfeder 243 eingespannt ist, wodurch dieWelle 233 mit ihremBund 244 leicht gegen das Lager 234 gedrückt wird. The diamond 228a used for dressing the grinding wheel A protrudes from the outer end of a sleeve 229 and is held in the sleeve in a known manner by a bolt 23o which, on the other hand, is threadedly connected to the sleeve. The sleeve 229 is mounted in a bore 231 of an arm 232 consisting of a shaft 233 in one piece. The shaft 233 is rotatably arranged in a bearing 234 of a stand 234 'fastened by screws 235 to the bearing sleeve 23b of the grinding wheel spindle. The sleeve 229 is held in place in the bore 231 by a suitable clamping screw 235 ′. On its offset part 236, the shaft 233 carries a sleeve 237 designed as a worm wheel 238 on one side. A worm 239 fastened to the shaft 24o is in engagement with the worm wheel 238. The shaft 240 mounted in the stator 234 'carries a hand crank 241, through the rotation of which the shaft 233 swings its arm 232 from the rest to the working position to the flat surface of the grinding wheel A (Fig. I). The housing 49a is provided with a cutout 242 at this point in order to allow the diamond to pass through. A nut is screwed onto the outer end of the shaft 233, between which and the bushing 237 a helical spring 243 is clamped, whereby the shaft 233 with its collar 244 is pressed slightly against the bearing 234.
