Definitions

  • the invention relates to a honing tool having one or more separate hydraulic expansion systems controlled by a mechanically actuated movement.
  • Honing is a machining process with geometrically indefinite cutting edges for almost all materials; It is often the last production process in production. The aim is to improve the dimensional and form accuracy and to positively influence the tribological properties.
  • a honing tool regularly executes a two-component cutting movement within a bore to be machined, during which rotational and axial movement are superimposed. This gives the machined surface defined crossed traces of these cutting movements, which are also referred to as honing or cross-grinding.
  • honing or cross-grinding For example, in engine construction, cylinder surfaces (inner surfaces of cylinder bores or cylinder liners) and bearings for shafts undergo honing to obtain finished surfaces that meet extremely high dimensional and dimensional tolerances and surface structure requirements.
  • the process is rinsed copiously (usually with honing oil or water-based cooling lubricant). Machining is often done in a strong stream of liquid to quickly rinse the material particles out of the processing room and dissipate the resulting heat.
  • Honing is already known by applying the cone in the tool with cooling lubricant (DE 10 2008 017 956.6).
  • the cooling lubricant serves for expansion and cooling.
  • the honing process is controlled via the activation or deactivation of the application of cooling lubricant via the honing machine.
  • Various switch-off criteria eg air flow rate determination via differential pressure measurement or time
  • Honing tools with double widening are also prior art, z. EP1815944. In this case, a honing tool is usually actuated by means of two separate expansion systems (hydraulically and / or mechanically acted upon).
  • the associated Delivery systems are provided by the honing machines and work via either a rod by means of pulling and pushing movement (Aufweitkegel are arranged against each other) in the axial direction or two rods, which also cause the delivery of the tools in the axial direction by pulling or pushing movement.
  • the double widening enables a cycle time reduction compared to two single machining operations, as the non-productive times (eg by eliminating the tool change) can be reduced.
  • the task is to realize a multiple honing process without tool change in the machining center.
  • the invention proposes a honing tool with the features of claim 1. Further developments of the invention are the subject of the dependent claims 2 to 10.
  • the invention proposes a honing tool with one or more hydraulic expansion systems, which in turn are actuated in each case via the cooling lubricant (FIGS. 1 and 2).
  • the control of the hydraulic expansion systems is realized by means of a mechanically controlled slide (9), which produces the fluid-effective connection of cooling lubricant and piston surface (5) of the cone (usually an annular surface).
  • the inlet (8) is opened to one of the expansion systems, the openings to the other piston surfaces are interrupted.
  • the tool cone (5) positively supports the honing stone support (4) in order to press the honing stones (2) against the workpiece to be machined. The smallest hole inside diameter of the workpiece limits the expansion movement.
  • the coil spring (14) presses the tool cone (5) back axially and the spring rings (7) pull the beam carriers (4) radially together.
  • the release openings (13) serve to relax the tool at the end of the machining process.
  • the coolant can escape radially.
  • the cooling lubricant can be supplied via an existing internal cooling through the pressure line (10) or from the side of the tool.
  • the linear or rotary movement of the control slide (9) can be brought mechanically through the spindle or be effected mechanically laterally from the honing tool.
  • suitable means e.g., a fine thread or screw
  • the invention proposes that the freedom of movement of the control slide (9) for a mechanical adaptation of measuring strips (16) to the diameter of the workpiece take place (FIG. 8).
  • the measuring strips (16) on support strips (17) are arranged, which are adjustable with the spool (9) in its diameter.
  • larger machining allowances can be processed and still the size of the hole at the end of processing by means of air flow rate determination by differential pressure measurement can be determined.
  • the descendants of the measuring nozzles will be necessary because of one certain distance of the measuring nozzles (15) for drilling the linear course of the distance determination is no longer given (critical cross-section).
  • the invention also proposes to design the control slide (9) so that it can actuate a mechanical expansion system with an axial movement in the opposite direction to the opening of the hydraulic expansion systems.
  • the mechanical expansion has the great advantage that during the movement of the spool (9) in a position and the expansion of the honing stones (L) moves to the associated position and thus the bore will always have the same size after machining. There will only be very little wear on the honing stones (1) of this expansion system during the process, which tends to make the bore smaller. This tendency can be detected downstream in the course of processing and compensated control technology (wear compensation).
  • This expansion system can be used to machine bores to a precise diameter (e.g., as a pre-honing operation), to then hydraulically finish, or to honed the hole into the tolerance field as finished honing without further control.
  • this system can be used in machining centers (BAZ), in which the tool is and the component performs the rotational and axial movements, as then easily and without mechanical additional effort an axial or rotational movement to control the slide on the tool are performed can.
  • BAZ machining centers
  • the spool (9) is in the starting position (FIG. 3).
  • the effect of the cooling lubricant on the hydraulic expansion systems is switched off, but it is already the coolant pressure in the tool.
  • the tool In this position, the tool is brought into the hole. Either the tool moves into the bore of the workpiece or the workpiece is moved onto the tool.
  • the first operation e.g. Prehone be performed (Fig. 4).
  • the control slide (9) is moved by means of a rotary or linear movement into the control position (FIG. 5), which makes the cooling lubricant volume flow to the respective hydraulic expansion system effective.
  • the spool (9) moves to a position for closing the inlet (8), so that the hydraulic actuation of the piston surface is interrupted and the expansion cone (5) is pushed back axially by means of a helical spring (14) (FIG. 7).

Abstract

L'invention porte sur le rodage. Dans un procédé de rodage, le fait d'exécuter plusieurs passes distinctes conduit à des temps morts, en raison du changement d'outil. Le nouvel outil de rodage permet un travail de rodage multiple au moyen d'un seul outil, sans changement dans le centre d'usinage. Selon la position d'un poussoir de commande mécanique (9), un ou plusieurs cônes d'outil additionnels (5) peuvent être sollicités et ainsi commandés à des instants distincts par l'introduction (8) d'un milieu non solide dans une conduite de pression (18). Ce système peut être utilisé de façon particulièrement avantageuse dans les centres d'usinage (BAZ).
