Definitions

  • the invention relates to a roll grinding machine for contour grinding of rolls with a device for tracking a grinding wheel mounted on a grinding spindle tangentially to the roll contour.
  • Such roll grinding machines are used to machine work and back-up rolls used, for example, in sheet metal, plastic and paper rolling mills.
  • these rollers always have a contour which deviates from the pure cylindrical shape, for example a hollow or spherical contour or a combination thereof.
  • a grinding wheel almost always grinds a roller with only one edge because of its shaft or grinding spindle running parallel to the center of the roller and is therefore not used over the entire surface.
  • very small longitudinal feeds are used in order to avoid a step formation in the roller, with the proviso that the grinding times are extended accordingly.
  • the grinding machine is designed with the possibility of a swiveling movement of the upper support.
  • this not only requires an additional separation of the support, it is also very difficult to generate this pivoting movement around the fixed pivot point absolutely hysteresis-free and at the same time to achieve the damping in the parting surface required for the grinding process.
  • the invention is therefore based on the object of improving the tangential tracking of the grinding wheel in a roll grinding machine of the type mentioned, in particular simplifying its construction and making it possible with greater accuracy.
  • the grinding spindle is arranged in a rotatable sleeve, preferably designed as an eccentric sleeve, the longitudinal axis of which is inclined at an angle to the longitudinal axis of the grinding spindle.
  • the grinding spindle moves with a main movement lying in the plane of the center of the workpiece and the center of the grinding spindle and adjusts itself to an angle corresponding to the degree of rotation to the center line of the workpiece.
  • This angle can be calculated as a tangent to the curve via an NC control of a higher-level computer, which is preferably connected to the roll grinding machine.
  • a preferred embodiment of the invention provides that the intersection of the two longitudinal axes lies in the center of the grinding wheel. Because of the fixed intersection point thus achieved, the grinding spindle can be turned on or tracked without the distance between the center points of the workpiece or the roller and the grinding spindle changing significantly. The accuracy of the tangential tracking can be further increased in this way.
  • both the sleeve and the eccentric bushing are preferably pretensioned at both ends, the precision when tracking the grinding wheel becomes even greater.
  • Hydrostatic bearings or preloaded are suitable for preloading Rolling guides that can be used without any problems due to the rotary movement when the grinding spindle is adjusted or adjusted.
  • the very large mechanical translation achieved according to the invention between the angle of rotation of the sleeve and the angle of rotation of the grinding spindle also contributes to the fact that the feed movement of the grinding wheel during tracking to the roller contour is reduced by this ratio in a ratio of approximately 1: 100.
  • An embodiment of the invention provides that the sleeve is arranged concentrically on an eccentric bush receiving the grinding spindle.
  • the grinding spindle is therefore no longer arranged directly in the inclined sleeve, but indirectly via the inner eccentric bushing, so that a double eccentric which is particularly suitable for fine adjustments or adjustments can be achieved.
  • Figure 1 in a very schematic front view as a detail of a roller grinder known per se whose grinding wheel can be adjusted to the contour of a roller by a pivoting movement of the upper support, as realized in the prior art;
  • FIG. 2 shows, as a detail from FIG. 1, the grinding wheel set in various positions over the length of the roller to be ground;
  • FIG. 3 shows a grinding wheel that deviates from FIG. 2 tangentially and has an approximately full wheel width on the contour of a roller;
  • FIG. 4 shows a greatly simplified illustration of a grinding wheel mounted on an eccentric bushing and set against a roller, in the front view; 5 shows a section along the line VV in Fig. 4.
  • FIGS. 4 and 5 shows as a detail a basic sketch of the kinematics when the grinding wheel is adjusted by rotating the eccentric sleeve according to FIGS. 4 and 5;
  • Fig. 7 is a representation corresponding to FIG. 5 of the mounting of the grinding spindle, which is arranged here in a double eccentric.
  • the grinding spindle 7 is arranged rotatable sleeve 8, the longitudinal axis 9 of which is inclined at an angle 10 to the longitudinal axis 11 of the grinding spindle 4.
  • the intersection 12 of the two longitudinal axes 9 and 11 lies in the center of the grinding wheel and is therefore fixed locally.
  • the grinding spindle 7 is connected via a drive means 13 to a drive (not shown) of the roll grinding machine.
  • the zero position of the grinding wheel tracking results from FIG. 4, in which a point 14 or 15 (cf. FIGS.
  • the grinding spindle 4 thus adjusts itself at an angle 10 to the center of the roller 16 in accordance with the adjustment dimension, without decisively changing the distance between the center of the roller 16 and the center of the grinding spindle 17.
  • ⁇ C of the sleeve 8 and the swivel angle ⁇ of the grinding spindle 7 there is a large mechanical translation which reduces the infeed movement by a ratio of approx. 1: 100.
  • the grinding spindle 7 is arranged in an eccentric bushing 19, which in this case is concentrically enclosed by the oblique sleeve 108 arranged on the outside and causing the inclination with respect to the longitudinal axis 11 of the grinding spindle 7.
  • the double eccentric achieved due to the nesting of the eccentric bushing 19 and the inclined sleeve 108 allows the tracking movement of the grinding wheel 4 to be finely adjusted.
  • the arrangement with rotary movements for adjusting the grinding wheel 4 allows the sleeve 8 or the sleeve 108 and the eccentric bushing 19 to be provided at both ends with a hydrostatic bearing 20 or 21 and thus to be preloaded; the hydrostatic cushion of the bearings 20 and 21 is indicated schematically in FIGS. 5 and 7 without the feeds for the pressure fluid demonstrate.
  • FIGS. 5 and 7 it is possible to adjust the grinding wheel 4 tangentially to the respective roller contour with great precision, the double eccentric according to FIG. 7 also allowing an additional fine adjustment.

Abstract

L'invention concerne une machine à rectifier les cylindres (2), utilisée pour rectifier le contour de cylindres, comportant un dispositif, simple du point de vue de la technique de construction, servant à l'application très précise d'une meule (4), montée sur une broche porte-meule (7), tangentiellement contre le contour d'un cylindre. La broche porte-meule (7) est disposée dans une douille (8) pouvant tourner, dont l'axe longitudinal (9) est incliné à certain angle (10) par rapport à l'axe longitudinal (11) de la broche porte-meule (7).
