Definitions

  • the present invention relates to a tool carrier which is intended to be arranged on the work spindle of a lathe for machining a workpiece.
  • Tool carriers for tools for attachment to the work spindle of a lathe are known and are used to machine workpieces made of any material. Depending on the work to be carried out, the appropriate tools must be selected and attached to the tool carrier, which is sometimes associated with complex changeover times (non-productive times). To avoid this, structurally complicated and costly turret heads with different tools are used.
  • the object of the present invention was to
  • the tool carrier enables two different tools to be held and used selectively, the costs for the components of the carrier and their number being kept to a minimum, in particular if the movement of the components of the A single motor is used for the carrier, the shaft of which moves both the slide and the desired tool holder selectively, e.g. via a lever with an inner curve and two cam disks or via two control cams for the two tool holders (plunge slide), an intermediate gear and a control curve for the slide (Cross slide).
  • the forced movement sequence is controlled sequentially or simultaneously along the movement axes X and Y or translationally. This ensures that idle times in tool selection are reduced to a minimum.
  • several tool carriers can be arranged on the spindle (each with two different tools), preferably at angular intervals of 120 °, which on the one hand excludes the risk of collision between neighboring tools and on the other hand reduces the idle time during tool selection to zero. Thanks to this surprising concept, the productivity of a lathe is sustainably increased at low costs.
  • each double tool can also be expanded by a working level (along the Z axis).
  • Fig. 2 shows a tool holder according to the invention with particularly advantageous drive means in three different positions with respect to the spindle, and
  • FIG. 3 shows a variant of the tool carrier according to FIG. 2.
  • Figure 1 of the drawing shows purely schematically a tool carrier according to the invention, with a central drive motor 1, a base carrier 8, on which a transversely displaceable carriage 5 with two tool holders 6, 6 'is arranged. Different tools 9, 9 'are held in the holders 6, 6'. Behind the cover 10, which is connected to the carriage 5 and is displaceable, there is the actual drive of the control elements 2 and 3, 3 '(see FIG. 2).
  • the base plate 8 is usually built on a Z-slide (not shown), which allows the additional controlled movement in the Z-direction (along the spindle).
  • Figure 2 illustrates schematically the functional principle of the double or twin tool carrier:
  • the motor 1 drives the control elements lever 2 and cam 3 via the motor shaft 1 '.
  • the lever 2 with an inner curve 2 ' serves to deflect in the transverse direction (Y) of the slide 5 up to adjustable stops 4 (for example, raster screws), the travel limitation serving the middle position (FIG. 2, left outside) of the tools 9, 9'.
  • the two cams 3, 3 ' serve to bring the desired tool to the working diameter (in the X direction).
  • the shift in the Y direction can be done as shown using lever 2 (up to the desired stop, if the motor shaft is turned further, the follower of the
  • the motor shaft 1 ' starting from the central position, can be rotated up to 180 ° on both sides.
  • several tool carriers can be arranged around a spindle, and the advantages described can be used in many ways. The increase in performance that can be achieved thereby makes it possible to replace the cam-controlled automatic lathes that were previously regarded as "irreplaceable".
  • FIG. 3 shows a variant of the tool carrier according to FIG. 2, in which the control lever 2 (FIG. 2) has been replaced by an intermediate gear 102 and a control cam 103 for the slide 105 (cross slide) (driven by the drive wheel 100). This ensures that the slide 105 can move into the desired working position.
  • the use of the intermediate gear 102 also ensures that only one drive motor is required for both axis movements.
  • the control cam 103 controls the cross slide 105, the two upper control cams 106, 106 'the tool holder 107, 107' of the two tools 109, 109 '.

Abstract

L'invention concerne un porte-outil présentant un support de base (8; 108) sur lequel un chariot (5; 105) peut se déplacer, de manière commandée, transversalement à l'axe de broche (7; 107). Deux éléments de maintien d'outil (6, 6'; 107, 107') pouvant se déplacer parallèlement l'un à l'autre, servant à maintenir différents outils (9, 9'; 109, 109'), sont placés sur le chariot (5; 105). Ces éléments de maintien (6, 6'; 107, 107') peuvent se rapprocher ou s'éloigner, de manière sélective, de l'axe de broche (7; 107) selon un angle de 90° par rapport au sens de déplacement du chariot (5; 105). Ce porte-outil présente en outre des moyens d'entraînement (1, 2, 3, 3'; 100, 102, 106, 106', 103) servant à déplacer le chariot (5; 105) et les éléments de maintien d'outil (6, 6'; 107, 107') le long de leurs axes de déplacement (Y, Z) dans une position de travail prédéterminée.
