Description
DESCRIPCIÓN DESCRIPTION
La transmisión de movimientos adicionales a elementos rotatorios de máquinas-herramienta The transmission of additional movements to rotating machine tool elements
La invención se refiere a la transmisión de movimientos adicionales a elementos rotatorios de máquinas-herramienta, p.ej. la aproximación radial de herramientas giratorias, la sujeción automatizada de piezas de trabajo o un reajuste automático de la sujeción de piezas de trabajo durante el mecanizado. Por el documento DE 199 21 919 5 A1 se conoce un torno para el mecanizado de piezas de trabajo fijas con herramientas giratorias. Las herramientas son guiadas de forma móvil en carros en un elemento rotatorio en rotación y pueden ser desplazadas y paradas también una independientemente de la otra respecto a la pieza de trabajo. Para ello está previsto un engranaje planetario, cuyo movimiento de salida se transmite mediante una rueda cilíndrica de dientes rectos de dentado interior y exterior a un árbol de accionamiento de carro, que está conectado a su vez con un engranaje de tornillo sin 10 fin. De este modo es posible aproximar varias herramientas de forma independiente una de otra radialmente a la pieza de trabajo. No obstante, esto requiere un esfuerzo técnico relativamente grande. Con la rueda cilíndrica de dientes rectos de dentado interior y exterior no es posible usar un árbol de accionamiento de carro central para la aproximación sincrónica de las herramientas. El engranaje está integrado en un dispositivo multifuncional y no es adecuado para un montaje posterior en máquinas existentes. 15 The invention relates to the transmission of additional movements to rotating machine tool elements, eg the radial approach of rotating tools, the automated clamping of workpieces or an automatic readjustment of the clamping of workpieces during machining . From DE 199 21 919 5 A1 a lathe is known for the machining of fixed workpieces with rotating tools. The tools are guided mobile in carriages in a rotating rotating element and can also be moved and stopped independently of each other with respect to the workpiece. For this, a planetary gear is provided, whose output movement is transmitted by means of a cylindrical wheel of straight teeth of internal and external teeth to a carriage drive shaft, which is connected in turn with a worm gear 10. In this way it is possible to approximate several tools independently of each other radially to the workpiece. However, this requires a relatively large technical effort. With the cylindrical wheel of straight teeth of internal and external teeth it is not possible to use a central carriage drive shaft for synchronous approach of the tools. The gear is integrated in a multifunctional device and is not suitable for subsequent mounting on existing machines. fifteen
La presente invención tiene el objetivo de reducir el esfuerzo para la superposición de movimientos adicionales a elementos rotatorios de máquinas-herramienta. Este objetivo se consigue con un dispositivo según la reivindicación 1. The present invention aims to reduce the effort for the superposition of additional movements to rotating machine tool elements. This objective is achieved with a device according to claim 1.
A continuación, la invención se explicará más detalladamente con ayuda de un ejemplo de realización. Next, the invention will be explained in more detail with the aid of an exemplary embodiment.
La Figura 1 muestra la transmisión de un movimiento adicional a un elemento rotatorio 1 en una representación 20 esquemática; Figure 1 shows the transmission of an additional movement to a rotating element 1 in a schematic representation 20;
la Figura 2 muestra un elemento rotatorio 1 realizado como plato de sujeción. Figure 2 shows a rotating element 1 made as a holding plate.
Según la Figura 1, el husillo principal de una máquina-herramienta, que porta un elemento rotatorio 1, está sincronizado mediante un engranaje planetario con un árbol 14 para la transmisión de un movimiento adicional. El elemento rotatorio 1 está alojado para ello en el bastidor 5 de forma giratoria alrededor del eje del husillo 17 y se 25 hace rotar mediante el motor de husillo 15. En el elemento rotatorio 1, los carros 16, 16’ son guiados de forma móvil radialmente en la dirección de las flechas dobles 18, 18’. Para moverlos, un segundo movimiento debe superponerse al movimiento de rotación del elemento rotatorio 1. El accionamiento de los carros 16,16’ se realiza desde la rueda dentada 11 mediante el árbol 14 dispuesto de forma concéntrica respecto al eje de rotación 17, las ruedas cónicas 4 y los engranajes de tornillo sin fin 3, 3’ que cooperan con los carros 16, 16’. Mediante un engranaje planetario 19, la 30 rueda dentada 11 está en unión funcional con la rueda dentada 12, que está dispuesta de forma asegurada contra el giro en el elemento rotatorio 1. Para generar el movimiento adicional, en el engranaje planetario 19 está abridado un motor 13, que acciona directamente el piñón 8, que engrana en la rueda planetaria 7. La rueda planetaria 7 engrana a su vez en el dentado interior de la rueda principal 6. La rueda principal 6 está alojada en el eje central. El alma 9 está unida rígidamente a la rueda dentada 10. Finalmente, la rueda dentada 10 acciona la rueda dentada 11, de 35 modo que el árbol 14 gira con el movimiento de rotación superpuesto. Cuando el motor 13 está parado, los carros 16, 16’ no cambian su posición. Según el sentido de giro del motor 13, se aproximan en la dirección radial al eje de husillo 17 o se mueven hacia el exterior. Es ventajoso evitar masas no equilibradas con el movimiento sincrónico de los carros 16, 16’. En resumen, la rueda dentada 12 alimenta al engranaje planetario 19 el número de revoluciones del motor de husillo 15 y mediante la rueda dentada 11 se transmite el movimiento adicional al elemento rotatorio 1. 40 Es especialmente ventajoso que el eje de husillo 17 con la rueda dentada 12 y el árbol 14 con la rueda dentada 11 estén dispuestos de forma concéntrica. De este modo, el engranaje planetario 19 puede ser premontado como módulo compacto y es fácil reequipar una máquina con el mismo. According to Figure 1, the main spindle of a machine tool, which carries a rotating element 1, is synchronized by a planetary gear with a shaft 14 for the transmission of an additional movement. The rotary element 1 is housed for this in the frame 5 rotatably around the axis of the spindle 17 and is rotated by means of the spindle motor 15. In the rotary element 1, the carriages 16, 16 'are guided in a mobile manner radially in the direction of the double arrows 18, 18 '. To move them, a second movement must be superimposed on the rotational movement of the rotating element 1. The driving of the carriages 16,16 'is carried out from the toothed wheel 11 by means of the shaft 14 arranged concentrically with respect to the axis of rotation 17, the wheels bevels 4 and worm gears 3, 3 'that cooperate with carriages 16, 16'. By means of a planetary gear 19, the cogwheel 11 is in functional connection with the cogwheel 12, which is arranged in a secured manner against the rotation in the rotating element 1. To generate the additional movement, in the planetary gear 19 a motor 13, which directly drives the pinion 8, which engages in the planetary wheel 7. The planetary wheel 7 in turn meshes in the inner teeth of the main wheel 6. The main wheel 6 is housed in the central axle. The core 9 is rigidly attached to the sprocket 10. Finally, the sprocket 10 drives the sprocket 11, so that the shaft 14 rotates with the superimposed rotation movement. When engine 13 is stopped, cars 16, 16 ’do not change their position. Depending on the direction of rotation of the motor 13, they approach the spindle axis 17 in the radial direction or move outwards. It is advantageous to avoid unbalanced masses with the synchronous movement of cars 16, 16 ’. In summary, the sprocket 12 feeds the planetary gear 19 the number of revolutions of the spindle motor 15 and by means of the sprocket 11 the additional movement is transmitted to the rotating element 1. 40 It is especially advantageous that the spindle shaft 17 with the wheel Toothed 12 and the shaft 14 with the toothed wheel 11 are arranged concentrically. In this way, the planetary gear 19 can be preassembled as a compact module and it is easy to retrofit a machine therewith.
En una máquina-herramienta, el elemento rotatorio 1 puede estar realizado como portaherramientas para herramientas giratorias para el mecanizado de piezas de trabajo fijas. En la Figura 1 están representadas por 45 ejemplo cuchillas de corte 2, 2’ como herramientas. Otro ejemplo de realización muestra la Figura 2. Allí, el elemento rotatorio 1 está realizado como plato de sujeción. Las mordazas de sujeción 21 pueden ser reajustadas durante el mecanizado. In a machine tool, the rotating element 1 can be made as a tool holder for rotating tools for the machining of fixed work pieces. In Figure 1, cutting blades 2, 2 ’are represented as tools. Another embodiment shows Figure 2. There, the rotating element 1 is made as a holding plate. The clamping jaws 21 can be readjusted during machining.
