Definitions

  • the present invention relates to a head for a polishing machine with oscillating sector carriers.
  • the main object of the present invention is to eliminate the aforementioned drawback and to produce a head for a polishing machine with the sector carriers oscillating around a longitudinal axis.
  • the advantages obtained thanks to the present invention essentially consist in that the formation of circular scratches on the polished surface is avoided; that it is possible to increase the degree of finishing of polished surfaces; whereas, with equal treatment time and degree of finishing, it is possible to treat a larger area; that it is possible to increase the speed of advance of the polishing machine; that it is very reliable, even after a long period of operation.
  • each sector holder (12) is also given an oscillating movement around the 'respective horizontal axis (90).
  • each sector carrier by relative to the surface being treated is, for each 120 °, a closed curve which, over 60 °, is a spiral arc whose radius increases from the minimum value to the maximum value, the difference being equal to the axial translation of the shaft 9, and, on the successive 60 °, is a spiral arc whose radius decreases from the maximum value to the minimum value.
  • the transmission ratio of the gear train determined by the toothed wheels (4,5,14) is variable as a function of the desired frequency of the alternating axial movement and of the oscillatory movement of the sector carriers ( 12). Furthermore, it is advantageously provided to vary the lifting of the cam (6) as a function of the desired value for the axial displacement of the sector carriers (12).
  • the direction of inclination of the buttonholes (17) of two adjacent rings (10) can be discordant or respectively concordant, to obtain a discordant oscillation or respectively concordant of two adjacent sector carriers (12).
  • a head for a polishing machine according to the invention can be equipped with a variable number of sector carriers (12), depending on the specific use for which it is intended.

Claims (6)

  1. Kopf für eine Schleifmaschine mit einer vertikalen Motorwelle (1), die mit einem Bund (2) zum Antreiben eines Gehäuses (3) versehen ist, mit einer Vielzahl von Sektorenhaltern (12), von denen jeder auf eine entsprechende horizontale Welle (9) aufgekeilt ist,
    dadurch gekennzeichnet,
    daß ein erstes Zahnrad (4) auf die Motorwelle (1) aufgekeilt und ein zweites Zahnrad (5) auf derselben Welle frei laufend und unterhalb des ersten montiert und mit einem Ringnocken (6) mit einer Nut (7) fest verbunden ist, und daß ein Kranz (14) mit Innenverzahnung frei laufend und bezüglich der Motorwelle (1) exzentrisch montiert ist und in besagte Zahnräder (4, 5) eingreift;
    daß weiterhin die horizontale Welle (9) eines jeden Sektorenhalters (12) mit einem ersten vertikalen Bolzen (15), der eine Rolle (8) trägt, die in der Nut (7) des Nockens (6) geführt ist, und mit einem zweiten bezüglich der horizontalen Welle (9) transversalen Bolzen (11) versehen ist, der durch die Welle hindurch verläuft;
    und daß ein Ring (10), der mit dem Gehäuse (3) fest verbunden ist, auf der Welle (9) eines jeden Sektorenhalters (12) montiert und mit zwei länglichen Aussparungen (17) mit helicoidaler Spur versehen ist, die dazu dienen, die Enden des entsprechenden zweiten Bolzens (11) in der Weise zu führen, daß bei der horizontalen Rotation des Gehäuses (3) jeder Sektorenhalter (12) einer hin- und hergehenden Bewegung längs seiner zugehörigen Achse (90) und gleichzeitig einer Oszillationsbewegung um diese Achse (90) unterworfen ist.
  2. Kopf für eine Schleifmaschine nach Anspruch 1, dadurch gekennzeichnet, daß das Übersetzungsverhältnis der Zahnräder (4, 5, 14) in Abhängigkeit von der gewünschten Frequenz der hin- und hergehenden Axialbewegung und der Oszillationsbewegung der Sektorenhalter (12) veränderbar ist.
  3. Kopf für eine Schleifmaschine nach Anspruch 1, dadurch gekennzeichnet, daß das aktive Profil des Nockens (6) aus aktiven Sektoren zusammengesetzt ist, deren Zahl mit der Zahl der Sektorenhalter (12) identisch ist, und daß die Hublänge eines jeden dieser Sektoren in Abhängigkeit von der gewünschten hin- und hergehenden Axialverschiebung der Sektorenhalter (12) veränderbar ist.
  4. Kopf für eine Schleifmaschine nach Anspruch 1, dadurch gekennzeichnet, daß die Neigung der länglichen Aussparungen (17) der Ringe (10) bezüglich der Achse (90) der Welle (9) der Sektorenhalter (12) in Abhängigkeit von der gewünschten Amplitude der Oszillationsbewegungen der Sektorenhalter (12) um ihre Achse (90) veränderbar ist.
  5. Kopf für eine Schleifmaschine nach Anspruch 1, dadurch gekennzeichnet, daß die Neigungsrichtung der länglichen Aussparungen (17) der Ringe (10) von zwei benachbarten Sektorenhaltern (12) gleichlaufend oder entgegengesetzt ist, um eine gleichlaufende oder entgegengesetzte Oszillation der beiden benachbarten Sektorenhalter (12) zu erzielen.
  6. Kopf für eine Schleifmaschine nach Anspruch 1, dadurch gekennzeichnet, daß sie mit einer veränderlichen Anzahl von Sektorenhaltern (12) ausgerüstet ist.
