Definitions

  • the invention relates to a clamping device for workpieces made of wood, plastic and the like according to the preamble of claim 1.
  • clamping devices which are provided with a fixed stop against which the workpieces to be clamped.
  • the workpieces have different width and cross-sectional shape before and after processing and the position of the stop is tuned to the largest workpiece width, spacers between the workpiece and the stop are inserted for clamping less wide workpieces.
  • the handling of such clamping devices is therefore cumbersome.
  • the machining of the clamped workpieces is often insufficient, since an exact positioning and support of the workpieces are not guaranteed in the clamping device.
  • the invention has the object of providing the generic clamping device in such a way that workpieces of different width and cross-sectional shape can be clamped in a simple manner so that a highly accurate machining of the workpiece is ensured in the clamped position. This object is achieved in the generic clamping device according to the invention with the characterizing features of claim 1.
  • the stop can be adjusted to adapt to the respective width of the workpiece. As a result, it is no longer necessary to insert spacers between workpieces of different widths and the stop. As a result, the handling when using the clamping device is very simple. It is possible in a particularly advantageous manner to automatically adjust the stop programmatically in the required position. As a result, each individual workpiece can be assigned its own individual optimum clamping dimension, which can preferably already be determined during the drawing of the workpiece by means of CAD. Since it is not necessary to deposit the workpiece with tolerance-bearing spacers, the workpieces can be positioned with high accuracy in the clamped position. The stop can be adjusted in such a position that only the part of the workpiece to be machined projects beyond the workpiece support. This also results in a machining-optimized clamping ratio, so that the workpiece can be securely clamped.
  • the clamping device has two spaced juxtaposed stops on which the workpiece rests with one side. This results in an accurate alignment and positioning of the workpiece in its longitudinal direction. In particular, short workpieces can be created and tensioned on the two stops.
  • both attacks have a common drive. Then they are reliably adjusted in each case in the same position, so that the workpiece can be positioned exactly.
  • the clamping device is provided with two opposite and parallel to each other workpiece supports. This makes it possible to simultaneously clamp two workpieces and edit. This is especially beneficial if two are the same
  • each workpiece support advantageously has two associated stops spaced apart from one another. They are each adjustable together to adapt to the width of the workpiece.
  • the two stops of a workpiece support are adjustable in opposite directions in synchronism with the two stops of the other workpiece support. This results in a simple and time-saving adjustment of the attacks in the necessary stop position.
  • two oppositely adjustable synchronously stops are mounted on a common drive spindle in these two stop groups. It is provided with right and left-hand thread, on each of which a stop is mounted. By turning the drive spindle therefore sitting on her two attacks are adjusted in opposite directions synchronously. This ensures a very simple adjustment of the attacks, making handling much easier.
  • the clamping element can be easily and accurately adjusted to different high workpieces
  • the clamping element is advantageously adjustable by means of a threaded spindle transverse to the workpiece support. With the threaded spindle, the clamping element can be adjusted to the required position.
  • a piston of a cylinder is advantageously provided, with which the clamping element is pressed onto the workpiece, which is thus clamped between the workpiece support and the clamping element.
  • the threaded spindle is mounted in the piston.
  • the clamping device is provided with at least one clamping device with which the clamping device can be clamped on a console. It is thus easy and time-saving possible to remove the clamping device as needed from the console and replace it with another clamping device.

Abstract

L'invention concerne un dispositif de serrage servant à serrer des pièces en bois, en plastique ou similaire. Les pièces sont serrées entre un support de pièce (22, 23) et un élément de serrage (8) qui peut être réglé en hauteur par rapport au support de pièce (22, 23) pour serrer les pièces. Les pièces mêmes reposent contre au moins une butée. Afin que des pièces de largeur et forme de section transversale différentes puissent être serrées simplement de manière à garantir un usinage hautement précis de la pièce dans la position serrée, la butée peut être automatiquement positionnée pour s'adapter à la largeur de la pièce. De ce fait, la manipulation lors de l'utilisation du dispositif de serrage est très simple. Une mesure de serrage individuelle optimale peut être associée en termes de technique de programmation à chaque pièce. Un placement de la pièce avec des espaceurs entre elle et la butée n'est pas nécessaire.
