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 invention intends to remedy, and this by providing the machine with an eclipsable guide mounted so as to materialize when desired the axis of orientation of the turret so that by translation of the grinding spindle along its axis and taking into account the lateral offset of this spindle with respect to the aforementioned orientation axis, the useful face of the grinding wheel can be brought into the plane passing through this axis, by simply bringing said face into contact with the eclipsable 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 either of 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 moved angularly by 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 traversed by a vertickal sleeve 10 provided at its lower part with a flange 10a against which bears a disc 11 whose outer wall carries the graduation 11 a of a circular vernier which cooperates with a reference 10 b 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 example ple envisaged realization it was assumed that this mechanism was formed by two nuts 12, but it goes without saying that in more sophisticated machines can use a cylinder 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 mounting 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 somehow materializes the axis of orientation of the grinding wheel turret 6, and that also the rod 21 associated with the grooves 19a allows 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 (FIGS. 3 and 4) of the sharpening cutter, this maneuver being carried out by using the vernier 11 a and lowering the frame 4.
  • 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 tapered 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 to be used by displaying the cutting angel (value d) on the vernier associated with the carriage 4a or on the dial of the control panel.
