Description

Zum Messen der wirksamen Werkzeugschneidwinkel an Schneidwerkzeugen für die spangel>ende Verformung sind Geräte mit Tasthebeln zum mechanischen Anfühlen der Schneidflächen am Schneidezahn bekannt. Diese versagen aber völlig beim Messen kleinerer Werkzeuge. Das Messen ist sell)st an großen Fräsern, für die solche Geräte hauptsächlich gebaut werden, mit erheblichen Fehlern behaftet, da das Anfühlen z. B. der Freifläche eines Fräserzahnes vor nur wenigen Zehntel Millimetern Breite Schwierigkeiten macht, ja teils unmöglich ist. For measuring the effective tool cutting angles on cutting tools Devices with tactile levers for mechanical touch are used for deformation of the cutting surfaces on the incisor known. However, these fail completely when measuring smaller tools. The measurement is sell) st on large milling cutters for which such devices are mainly built, with significant errors, since the feel of z. B. the free surface of a cutter tooth just a few tenths of a millimeter wide Makes difficulties, sometimes impossible.

Die einzige Möglichkeit, eine solche Messung durchzuführen, bietet ein Universal- oder Werkzeugmikroskop. Das Ausrichten der Werkzeugschneide in die richtige Meßlage ist jedoch hierbei umständlich un dzeitraubend und kann meist nur im Prüfraum labormäßig für besondere Zwecke durchgeführt werden, für Werkstattmessungen ist dieses Verfahren unwirtschaftlich. Viele Werkzeuge können aber auch auf diese Weise nicht gemessen werden, da ihre Baulänge oder ihr Durchmesser hinderlich sind, z. B. Reibahlen, Senker, Tieflochbohrer, Scheibenfräser, Winkelfräser. The only way to carry out such a measurement offers a universal or tool microscope. Aligning the tool edge in the However, the correct measuring position is cumbersome and time consuming and can mostly only be carried out in the laboratory for special purposes in the test room, for workshop measurements this process is uneconomical. However, many tools can also access this Not be measured because their length or their diameter are a hindrance, z. B. reamers, countersinks, deep hole drills, side milling cutters, angle milling cutters.

Das Schneidwinkelmikroskop nach der Erfindung l'ietet die Möglichkeit, an allen vorkommenden Schneidwerkzeugen die wirksamen Schneidwinkel optische mit ausreichender Genauigkeit in kürzester Zeit zu messen, und zwar dadurch, daß erfindungsgemäß der Werkzeugträger um eine Achse und das Mikroskop um seine optische Achse drehbar angeordnet werden, und zwar derart. daß die optische Achse und die Werkzeugträgerachse, vorzugsweise in verschiedenen El>enen, aufeinander senkrecht stehen. The cutting angle microscope according to the invention offers the possibility of The effective cutting angles are also optically included in all cutting tools to measure sufficient accuracy in the shortest possible time, namely that according to the invention the tool holder is rotatable about an axis and the microscope is rotatable about its optical axis be arranged, in such a way. that the optical axis and the tool carrier axis, preferably in different el> enes, perpendicular to each other.

Die weitere Ausbildung der Erfidnung wird an Hand der Abbildungen beschrieben. The further development of the invention is based on the illustrations described.

Abb. 1 2 und 3 zeigen ein Ausführungsbeispiel in drei aufeinander senkrechten Ebenen; Abb. 4 zeigt das Bild eines Schneidwinkels im Mikroskop. Fig. 1 2 and 3 show an embodiment in three on top of one another vertical planes; Fig. 4 shows the image of a cutting angle in the microscope.

Claims (1)

Ein Werkzeugträger I ist um seine wachse 2 um 360° drehbar. Die eine Seite ist als 90° Hohlprisma ausgebildet, die gegenüberliegende Seite als ebene Meßfläche. An zwei rechtwinklig zueinander angeordneten Säulen 3 und 4 ist ein Spezialmikroskop 5 so angebaut, daß seine optische Achse senkrecht zur Achse 2 liegt und die senkrechte Achse eines eingebauten Strichkreuzes 6 genau durch den Scheitel des Holilprismas geht. Ein Mikroskopträger 7 ist auf einer Säule 4 verschiebbar und ermöglicht das Einstellen des Strichkreuzes 6 eiltsprechend dem Werkzeugdurchmesser oder der Werkzeughöhe. Ein Säulenträger 8 ist auf der Säule 3 zur Scharfeinstellung der Optik verschiebbar. Wird eine Rändelmutter 9 gelöst, so kann mittels einer gerändelten Skalenscheibe 10 an einer 360°-Strichteilung die gewünschte Meßebene am Werkzeugträger 1 zur optischen Achse des Mikroskopes 5 eingestellt werden. Es ist dadurch möglich, sowohl das Hohlprisma als auch die ebene Meßfläche des Werkzeugträgers 1 in jede beliebige 120 A tool carrier I can be rotated around its axis 2 by 360 °. The one Side is designed as a 90 ° hollow prism, the opposite side as a flat Measuring surface. A special microscope is attached to two columns 3 and 4 arranged at right angles to one another 5 grown so that its optical axis is perpendicular to axis 2 and the vertical Axis of a built-in line cross 6 exactly through the vertex of the Holil prism goes. A microscope carrier 7 is displaceable on a column 4 and enables this Adjusting the cross line 6 according to the tool diameter or the tool height. A column carrier 8 can be moved on the column 3 for focusing the optics. If a knurled nut 9 is loosened, a knurled dial can be used 10 at a 360 ° graduation, the desired measuring plane on the tool carrier 1 for the optical Axis of the microscope 5 can be adjusted. It is thereby possible to use both the hollow prism as well as the flat measuring surface of the tool carrier 1 in any 120
