Definitions

  • the subject of the present invention is a machine with digital control for the sharpening of cutting tools comprising a table intended to support and hold the cutting tool and a vertical column carrying at least two opposite grinding wheel heads orientable around 'a horizontal axis and capable of moving vertically on the column and electromechanical means for positioning the grinding wheel heads around their horizontal axis.
  • each of the grinding wheel heads must be positioned precisely around a horizontal axis. This positioning is ensured by digital control by means of a servomotor. There are therefore as many servomotors as grinding wheel heads.
  • the object of the present invention is to simplify the construction and control of a numerically controlled sharpening machine.
  • the machine according to the invention is characterized in that the two opposite grinding wheel heads are integral in rotation about a common horizontal axis and that they are orientable around this axis by common electromechanical means.
  • each grinding head had to be controlled by its own servomotor so as to be able to be controlled independently of another grinding wheel head
  • the corresponding grinding wheel head when a grinding wheel has finished its work and must be replaced by another grinding wheel, the corresponding grinding wheel head must move half a turn around the vertical axis to come to occupy its working position. The time necessary for this movement is amply sufficient to proceed with the proper orientation of this grinding wheel head around its horizontal axis.
  • the rotation of the grinding wheel head outside work around the common axis it obviously does not matter.
  • the invention becomes particularly interesting if the machine is equipped with four grinding wheel heads mounted in pairs on two common axes, each of these axes being controlled by a servomotor. This saves two servos, since you only need two servos instead of four. The machine is therefore simpler and the cost of its manufacture is reduced.
  • Figure 1 is a simplified front view in elevation of a sharpening machine with four grinding wheel heads.
  • Figure 2 is a side elevational view of this machine.
  • Figure 3 is a plan view of this machine.
  • Figure 4 shows the sharpening of a flat spindle using three different grinding wheels.
  • Figure 5 shows the sharpening of a round spindle using three different grinding wheels.
  • FIG. 6 illustrates the use of a fourth profiled grinding wheel for sharpening a profiled flat spindle.
  • FIGS 1 to 3 show a sharpening machine comprising a frame 1, a longitudinal slide 2 carrying a table 3 on which is fixed the sharpening tool, here a flat spindle 4.
  • the machine further comprises a transverse slide 5 on which is mounted a vertical column 6 which can rotate about a vertical axis 7 and move vertically.
  • On this column 6 are mounted four grinding wheel heads 8, 9, 10 and 11 orientable around a horizontal axis.
  • Each grinding wheel head comprises a motor 12 driving a grinding wheel 13.
  • Each grinding wheel head is mounted on a turret 14 fixed radially to the column 6.
  • the grinding wheel heads 8 and 10 are diametrically opposite relative to the vertical axis 7 They are coaxial and mechanically integral with a common axis. The same applies to the grinding wheel heads 9 and 11.
  • the mechanical axis of the grinding wheel heads 8 and 10 can be driven by a non-visible servomotor, in a manner known per se. The same applies to grinding wheel heads 9 and 11.
  • the machine is controlled in a well known manner by numerical control by means of a control cabinet 15.
  • the axes of the two pairs of grinding wheel heads have been shown to be coplanar, but they may very well be offset vertically with respect to each other.
  • FIG. 4 represents the spindle 4 of FIGS. 1 to 3.
  • the grinding wheel 16 of small thickness, comes to sharpen the face of the teeth of the spindle 4 by its conical surface.
  • the grinding wheel 17 sharpens the skin of the teeth by its flat front face.
  • the grinding wheel 18 is for example a chip breaking grinding wheel.
  • FIG. 5 shows a part of a round spindle 19 also requiring three grinding wheels for its sharpening, namely a grinding wheel 20 for sharpening the face of the teeth, a grinding wheel 21 for sharpening the skin of the teeth and a grinding wheel 22 similar to grinding wheel 18.
  • FIG. 6 partially represents a flat spindle 23 whose teeth 24 have a particular profile requiring a grinding wheel 25 having the corresponding profile.
  • This wheel 25 could be the fourth wheel of the machine illustrated in FIGS. 1 to 3.
