Description

Maschine zum Schleifbohren von Ziehsteinen. Die Erfindung hat eine Maschine zum Schleifbohren von Ziehsteinen zum Gegenstand. Gegenüber bekannten Arten unterscheidet sie sich durch große Einfachheit, gute Übersichtlichkeit und leichte Handhabung. Die Erfindung besteht darin, daß der hin und her gehende Steinhalter unmittelbar durdh einen unter demselben vorgesehenen verstellbaren Exzenter beeinflußt wird, der samt seiner Antriebsvorrichtung auf einem zur Beistellung bzw. Verlegung seines Hubes schwenkbaren und feststellbaren Hebel gelagert ist.Machine for grinding and drilling drawing dies. The invention has one Machine for grinding and drilling drawing dies to the object. Compared to known species it differs in its great simplicity, good clarity and lightness Handling. The invention consists in that the stone holder moving back and forth directly influenced by an adjustable eccentric provided under the same , which together with its drive device on one for provision or laying its stroke is mounted pivotable and lockable lever.

Auf der Zeichnung ist der Erfindungsgegenstand in einer Ausführungsform dargestellt, und zwar zeigt: Abb. z eine Seitenansicht und Abb. 2 eine Aufsicht.The subject of the invention is shown in one embodiment in the drawing shown, namely: Fig. Z is a side view and Fig. 2 is a plan view.

r bezeichnet einen Bock, der mit einem Lagerpaar 2, 2 für den Bohrerhalter 3 versehen ist. Auf einem zweiten Bock q. ist der Steinhalter 5 in halbzylindrischen offenen Nuten gelagert. Derselbe wird in bekannter Weise durch die Feder 6 gegen den Bohrer gedrückt. Um nun die hin und her gehende Bewegung des Steinhalters 5 einerseits herbeizuführen, anderseits den Bewegungshub in eitfachster Weise im Raum zu verlegen, ist der unterhalb desselben mit seiner Antriebsvorrichtung 8 auf einer vertikalen Welle 9 angeordnete Exzenter 7 auf einem um die zur Halterwelle 5 lotrechte Achse 13 schwenkbaren Hebel 12 gelagert. Der Exzenter 7 wirkt gegen eine Feder ro und diese gegen den Stift II des Steinhalters 5. Eine Feder 1q. zieht den Hebel 12 gegen den Gewindebolzen i 5, durch dessen Vor- oder Zurückschrauben der Hebel r2 verschoben und somit der Hub des Steinhalters 5 verlegt werden kann.r denotes a bracket which is provided with a pair of bearings 2, 2 for the drill holder 3. On a second box q. the stone holder 5 is mounted in semi-cylindrical open grooves. The same is pressed in a known manner by the spring 6 against the drill. In order to bring about the reciprocating movement of the stone holder 5 on the one hand, and on the other hand to relocate the movement stroke in the most simple manner in space, the eccentric 7 arranged below it with its drive device 8 on a vertical shaft 9 is on an axis perpendicular to the holder shaft 5 13 pivotable lever 12 mounted. The eccentric 7 acts against a spring ro and this against the pin II of the stone holder 5. A spring 1q. pulls the lever 12 against the threaded bolt i 5, by screwing it forward or backward, the lever r2 can be displaced and the stroke of the stone holder 5 can thus be relocated.
