Definitions

  • the invention relates to a method for grinding a rotationally symmetrical machine component with two axle parts and an intermediate therewith, enlarged in diameter central part, on which an active surface in the form of a particular flat truncated cone with a rectilinear or curved contour in cross section is formed.
  • Machine components of this type are, for example, in transmissions with continuously variable ratio, as required in motor vehicles.
  • two machine components face each other with facing active surfaces.
  • the active surfaces thus form a Ringraurn with approximately wedge-shaped cross-section, in which a tension member such as a chain or a belt depending on the distance of the active surfaces of each other back and forth between different radii. Since such a transmission must work very accurately and transmit large torques, high demands are placed on the dimensional accuracy and the surface quality of the machine components. This also applies to the associated grinding operations, especially when grinding the active surface.
  • the active surface is ground by means of corundum grinding wheels in Schräginstechmaschine.
  • the cylindrical outer surfaces of the associated axle parts are also ground, which are generally graduated in diameter.
  • a universal grinding station for tool grinding is known, which allows a variety of possible combinations in the mutual position assignment of grinding heads and tool carriers. Also known is a grinding head with two different grinding wheels (DE 37 24 698 A1), with the various grinding operations can be performed in a workpiece clamping. There is already a proposal (DE 199 21 785 A1) to grind relevant machine components in one clamping, with two separate grinding spindles are used.
  • the machine component to be ground thus remains in a single set-up in which all grinding operations are carried out.
  • the grinding spindle is pivoted about two mutually perpendicular pivot axes and in addition to the machine component parallel to its longitudinal axis and perpendicular to it (X-axis) is moved.
  • the grinding spindle can thus be brought into any desired position relative to the machine component, so that it is possible to grind both the active surface and further, located on the machine component cylindrical outer surfaces with grinding wheels of basically cylindrical contour.
  • the first grinding wheel of cylindrical basic shape will also have an outer contour that is rectilinear in cross-section in the case of an effective surface with a contour that is rectilinear in cross-section. If the effective surface is curved, the grinding wheel must have a slightly curved, adapted contour in cross-section in cylindrical basic shape. The bulges occurring in practice are very small.
  • the possibility of movement of the grinding spindle relative to the machine component parallel to its longitudinal axis opens up the possibility of grinding the active surface with the cylindrical peripheral surface of the grinding wheel in a perpendicular grinding process, said relative displacement effecting the feed. Since in the machine components of the type in question here the effective surface has the shape of a flat truncated cone, it is sufficient to make the feed during grinding of the active surface by the grinding spindle and the machine component parallel to its longitudinal axis and perpendicular thereto (X-axis ) is moved. Of this movement is attributable to the grinding point on the active surface only an obliquely directed component, but deviates only by a small amount from the direction of the longitudinal axis, so that there is almost a vertical grinding in the usual sense.
  • the advantage is a constant cutting speed over the entire width of the grinding wheel. This ensures an increased surface quality and surface structure.
  • optimized dressing parameters are obtained when dressing the grinding wheel, because during dressing the same parameters, namely a identical dressing speed as during grinding and the same speed ratios and feed values are achieved. Because the cutting speed of the grinding wheel remains the same over the effective surface, the achievable surface roughness is consistent. Due to the same cutting speed of the grinding wheel over the complete “conical surface", optimal values for the cutting volume per unit time can be achieved.
  • the outer diameter of the conical disk is assumed to have a diameter of, for example, 190 mm and a diameter of 40 mm adjoining the conical surface, the workpiece speed changes by a factor of 4.75 due to the rotation of the workpiece during grinding.
  • the height of the conical surface is thus about 75 mm.
  • the cutting speed at the outside diameter of the conical surface is then about 80% of the cutting speed of the grinding wheel at the small diameter of the conical surface. This is opposite to the cutting volume, since this is highest at the large diameter at the conical surface.
  • the cutting speed ratio to the cutting volume, which must be removed via the conical surface is substantially improved by the grinding wheel set perpendicular to the conical surface.
  • the grinding process according to the invention can therefore be carried out optimally with ceramic-bonded CBN grinding wheels. Overall, a significantly reduced number of cycles on modern processing machines at the same time considerably improved grinding result.
  • the active surface of the machine component is ground by a grinding wheel located on the first grinding wheel of cylindrical shape and rectilinear or adapted curved peripheral contour is made perpendicular to the active surface, wherein the axial extent of the grinding wheel covers the radial oblique stretch of the active surface and the delivery takes place by the grinding wheel and the machine component are moved in the direction of its longitudinal axis relative to each other.
  • the first grinding wheel has a greater axial extent, so that the entire active surface can be finished in a process of vertical grinding.
  • the effective surface of the machine component is a truncated cone shell with a contour which is rectilinear in cross-section
  • the first grinding wheel can have a cylindrical shape.
  • a curved cross-section contour of the active surface and a suitably curved peripheral contour of the first grinding wheel is required.
  • a second grinding wheel is used with which the said cylindrical outer surfaces are ground by longitudinal grinding;
  • the second grinding wheel is coaxially with the first grinding wheel on the grinding spindle and the second grinding wheel preferably has a significantly smaller width than the first grinding wheel, so that a longitudinal grinding of cylindrical outer contours can be made easily.
  • the longitudinal grinding of the cylindrical outer surfaces located on the machine component takes place by means of peeling grinding, in which grinding is carried out in a known manner in one pass down to the final dimension. Since all the prerequisites for a high-quality grinding process are present as a result of the constant clamping, it is possible here to work in the peeling method, whereby the cycle time is further reduced with high grinding quality.
  • the cylindrical outer surfaces to be ground can ggs. also be edited by plunge grinding.
  • the machine component is advantageously clamped between tips and driven from at least one of the tips for rotation.
  • the exact centering is least disturbed despite the rotary drive. This also results in a high quality of the grinding result.
  • the invention also relates to a device for grinding a rotationally symmetrical machine component of the type mentioned at the outset already mentioned in connection with the method. It consists in a device according to the features of claim 7.
  • the device according to the invention comprises a flying arrangement of both grinding wheels on one and the same side of the grinding spindle. This results in a structurally simple design of the grinding spindle, which is readily achievable by grading the diameter of both grinding wheels, that the two grinding wheels do not interfere with each other in the different processing operations.
  • the clamping and drive members are formed for clamping the machine component by attached to a workpiece headstock and tailstock quills centering with them at the tips engage in frontal bores of the machine component, and if at least located on the workpiece headstock with a coupling is provided, which communicates with the frontal bore of the machine component via radially acting from inside to outside tendons for the purpose of the rotary driving in operative connection.
  • the rotary drive of the machine component from the inside of a centering this machine component tip means that the centering is not disturbed by the rotary drive.
  • the radially outwardly acting tendons do not apply axial forces to the machine component and the tips.
  • stresses and deflections of the machine component remain despite a reliable rotational drive. It is thus a reliable rotary drive connected to a centering of high consistent accuracy.
  • such a coupling can be realized in that it is designed as Sp Dr Druskupplung whose outwardly to be spread tenders are designed as clamping jaws and are arranged in the region of the tip of a longitudinal bore of the workpiece headstock shaft, and that the actuation of the Tensioning members by a tie rod, which is passed through the longitudinal bore and provided in the clamping jaws with a Betäf Trentskonus.
  • the required mutual longitudinal displacement of the machine component and the grinding spindle slide can advantageously be realized in that the clamping and drive members for clamping and for rotary drive of the machine component are located on a grinding table which is movable relative to the grinding spindle slide in the longitudinal direction of the machine component.
  • a grinding headstock is arranged on the grinding spindle slide via a first pivot axis perpendicular to its displacement plane, on which the grinding spindle is pivotable about a second pivot axis, which is perpendicular to the first pivot axis runs.
  • the grinding spindle can be brought particularly advantageous in the various processing positions on the machine component, wherein the two grinding wheels do not interfere with each other.

Abstract

L'invention concerne un procédé et un dispositif pour rectifier un élément de machine (17) constitué de deux parties axiales (18, 19) et d'une partie médiane (20) de diamètre D nettement supérieur. La partie médiane (20) comporte une surface active (22) présentant sur une partie la forme d'un cône tronqué (21) plat. Pour usiner la quantité à rectifier (25) sur la surface active (22), l'élément de machine (17) est inséré entre des extrémités (6, 7) de tiges (4, 5), la tige (5) disposée au niveau de la contre-pointe (3) étant soutenue par une lunette (27). L'élément de machine (17) est déplacé dans le sens de son axe longitudinal (23) et la ligne de contact (28) de sa surface active (22) est approchée contre la meule (15). Il est ainsi possible de réaliser un meulage vertical avec le contour extérieur cylindrique de la première meule (15), la vitesse de coupe sur l'ensemble de la surface axiale de la première meule (15) étant constante, d'où une rectification de très bonne qualité. La première meule (15) et une deuxième meule (16) plus étroite sont logées mobiles sur une broche porte-meule (14). Faire pivoter cette broche (14) autour de deux axes mutuellement perpendiculaires et déplacer ladite broche (14) perpendiculairement à l'axe longitudinal (23) permet de mettre la deuxième meule (16) en une position de travail, dans laquelle les parties extérieures cylindriques de l'élément de machine sont usinées par meulage longitudinal, l'élément de machine (17) restant alors dans la même fixation. Le procédé de l'invention permet d'exécuter un très bon meulage à des cadences de production plus rapides.
