Definitions

  • the present invention relates to machines for sharpening cutters and other machining tools.
  • the interchangeable grinding wheel is generally mounted with its electric drive motor on a turret carried in rotation by a frame capable of being adjusted in height along a vertical column, itself adjustable in transverse position relative to a horizontal bench.
  • the operator is thus able to bring the useful part of the grinding wheel to its exact desired position for sharpening the tools to be worked, which are fixed on a headstock movable axially along the aforementioned bench and are capable of being animated. an axial translational movement and / or angular displacement.
  • the useful part of the grinding wheel is profiled as a function of the sharpening work to be carried out, so that the grinding spindle receives in fact, during the use of a machine considered, grinding wheels of very large dimensions. different, especially in thickness (length along the axis).
  • the operator must carry out complicated calculations to determine the exact positioning to be assigned to the grinding wheel considered in order to achieve a precise cutting angle on the tool to sharpen.
  • This preliminary calculation already troublesome on manual adjustment machines, in practice eliminates the advantages of simplicity presented by modern sharpening machines with digital display, since prior to display the operator must carry out the exact determination of the settings.
  • the invention essentially consists in making the machine on the one hand an eclipsable guide mounted so as to materialize when desired the axis of orientation of the grinding wheel turret, and on the other hand an adjustment mechanism capable of bringing the useful part of the grinding wheel to the contact with the aforementioned guide.
  • the reference 1 designates the fixed horizontal bench of the sharpening machine, on which the headstock 2 moves for fixing the tool to be worked, shown diagrammatically at 3; the headstock 2 is capable of either being fixed in an adjustable manner along the bench 1, or of being driven in a longitudinal movement back and forth, depending on the nature of the sharpening to be carried out; in the same way and in the usual way the tool 3 can, when desired, be angularly moved in jerks according to a variable amplitude.
  • the lower part of the bench 1 is arranged to form a sliding guide for a transverse carriage 4a, vertically integral with a column 4.
  • the latter supports in an adjustable manner a frame 5 mounted cantilevered above the bench 1.
  • this frame 5 In conventional machines, it is the underside of this frame 5 which directly carries the turret 6 in an orientable manner, inside which is housed the electric motor 7 for driving the spindle 8 intended to support the grinding wheel. sharpening 9.
  • the frame 5 is crossed by a vertical sleeve 10 provided at its lower part with a flange 10a against which bears a disc 11 whose outer wall carries the graduation lla of a circular vernier which cooperates with a reference 10b of the flange 10a, said disc being attached against the underside of the frame.
  • the upper end of the sleeve 10 protrudes above this frame and is equipped with a mechanism for the angular locking of said sleeve; in the exemplary embodiment envisaged, it has been assumed that this mechanism was formed by two nuts 12, but it goes without saying that in more sophisticated machines, it is possible to have recourse to a jack or other immobilization system with immediate action.
  • the annular flange 10a is made integral with a horizontal sole 13 having in cross section a dovetail profile on which slides a carriage 14; the latter is maneuvered using a flywheel 15 fixed at the end of a threaded rod 16 which cooperates with a nut 17 secured to the carriage 14 and which is retained axially in an eyelet 18 secured to the sole 13. It is on the carriage 14 that the upper part of the grinding wheel turret 6 is fixed, which is thus capable of being adjusted in position.
  • a sliding guide 19 provided with ball bushings 20 which ensure the precision of its assembly while leaving it free to move axially and angularly.
  • the immobilization of the guide 19 is ensured using an operating rod 21 which selectively cooperates with one or the other of two grooves 19a.
  • This guide 19 passes vertically through the sole 13 through a circular opening, then the carriage 14 and the upper part of the turret 6 through elongated openings which allow the horizontal displacement of said turret. Its lower end 19b is cut to present in section a substantially triangular profile.
  • this guide 19 materializes in a way the axis of orientation of the grinding wheel turret 6, and that moreover the rod 21 associated with the grooves 19a makes it possible to immobilize it either in the low position of use, or in high eclipsed position.
  • the operator firstly lowers the guide 19 until it reaches the low position and then operates the flywheel 15 to move the turret 6 and bring the working face 9a (fig 3) of the grinding wheel 9 in contact with the tip of the lower part 19b of the guide. It is at this point certain that this face 9a coincides with the axis of rotation of the turret 6.
  • the turret 6 is pivoted so as to engage the grinding wheel 9 in the propeller or slope 33 (fig. 3 and 4) of the sharpening cutter, this maneuver being carried out with the help of the vernier lla and by lowering the frame 4. This done, it suffices to move transversely by a distance d (fig.
  • This setting mode allows the machine to be adapted almost immediately to the different types of grinding wheels used for sharpening machining tools.
  • the drive spindle 8 can be equipped with a flat grinding wheel or a large frustoconical grinding wheel since once the working face 9a of this grinding wheel brought into contact with the tip of the lower part 19b of the guide 19, the machine is ready for use by displaying the cutting angle (value d) on the vernier associated with the carriage 4a or on the dial of the control panel.
