Definitions

  • the invention relates to a device for relief grinding and polygon grinding on grinding machines according to the preamble of claim 1.
  • a device for relief grinding and polygon grinding on grinding machines according to the preamble of claim 1.
  • Such a device is used in particular for machining taps and can be used in general for machining drills.
  • a device of the generic type is previously known from DE-PS 22 09 809.
  • the lever is firmly connected to the bearing body of the workpiece spindle shaft, its longitudinal axis runs exactly through the pivot axis of the bearing body and the axis of the spindle shaft is arranged at a small lever distance from it.
  • the lever distance can be adjusted by eccentrically mounting the spindle shaft.
  • the invention is therefore based on the object of providing a device for relief grinding and polygon grinding on grinding machines of the generic type, with which, in all intermediate positions between the relief grinding movement zero and the maximum, only relief grinding movements in the longitudinal direction of the lever are carried out, which should be precisely adjustable .
  • the sliding surface elements are expediently formed from the two halves of a cylinder piece divided longitudinally along its axis, one half of which is movably supported in bearing shells at the free end of the lever and the other half at the housing.
  • the inclined sliding surface is at an acute angle to the vertical through the longitudinal axis of the lever. In the rest position, d. H.
  • the plane of the sliding surface is parallel to the plane that runs through the axes of the spindle shaft and the swivel bearing of the bearing body.
  • the sliding surface element fixed to the housing is expediently pivotable by means of an adjustment drive in order to be able to adjust the relief grinding movement from a value of zero to a maximum value.
  • a measuring and heating element connected to a control unit is inserted in the lever in order to be able to monitor the length of the lever and the position of the longitudinal central axis of the lever.
  • the length of the lever is monitored via its temperature, with an influence on the length of the lever and thus on the diameter of the workpiece to be machined being possible by heating the heating element or by cooling.
  • the position of the longitudinal central axis of the lever is monitored by a measuring element in the form of an angular position encoder.
  • the pivot axis of the bearing body is formed from a torsion shaft.
  • the device for relief grinding and polygon grinding on grinding machines comprises a housing 1, in which a bearing body 2 around a shaft 3 designed as a torsion shaft are pivotable and a camshaft 5 carrying a cam 4 are rotatably mounted.
  • a workpiece spindle shaft 6 is rotatably mounted about its axis 7, which is arranged at a distance X from the axis of the torsion shaft 3.
  • the axis 7 of the workpiece spindle shaft is arranged parallel to the axis 9 of a grinding wheel 10, with which a workpiece inserted into the spindle shaft 6, in particular a tap, can be brought into engagement for regrinding.
  • tips 11 or clamping jaw chucks 12 can be used, which can be attached to the free end of the workpiece spindle shaft 6.
  • a drive gear 13 which is motor-driven in a manner not shown, is supported, which meshes with an output gear 14, which is attached to the axis 7 of the workpiece spindle shaft 6.
  • the rotary drive of the workpiece spindle shaft 6 is effected, specifically regardless of a possible pivoting movement of the bearing body 2 together with the workpiece spindle shaft 6 about the pivot axis 8 of the bearing body 2.
  • a lever 16 is arranged in the articulation point 15, the longitudinal axis 17 of which is substantially perpendicular to the connecting line between the axis 3 of the bearing body and the spindle axis 7.
  • the lever 17 carries on its underside a cam follower roller 18, which is in engagement with the guide curve arrangement 4, 5, and on its opposite side a spring 33 supported on the housing 1, which constantly pivots the lever 16, which is pivotably mounted about its articulation point 15, against the guide curve arrangement 4 , 5 presses.
  • a pivoting movement of the lever 16 is to be converted by means of a sliding device 19 into a linear movement along the longitudinal axis 17 of the lever 16, which acts on the bearing body 2 at a distance X from the pivot axis 3.
  • the sliding device 19 is formed from two inclined sliding surface elements 20, 21, of which the sliding surface element 20 is attached to the free end of the lever 16 within a bearing shell 22 and the sliding surface element 21 on the housing 1 by means of a further bearing shell 23.
  • This is adjustable by means of an adjustment drive 24 which is formed from a worm wheel 25 attached to the bearing shell 23 and a worm 26 which is rotatably mounted in the housing 1 on a shaft 27 and can be adjusted from outside via a control unit 28.
  • the two sliding surface elements 20, 21 are formed from the two halves of a cylinder piece divided longitudinally along its axis.
  • the sliding plane 29 is perpendicular to the longitudinal axis 17 of the lever 16 when a relief grinding movement of zero value is to be carried out.
  • the sliding surface plane 29 is parallel to a plane which runs through the axes 3 and 7.
  • the sliding surface plane 29 is inclined at an acute angle ⁇ against the vertical through the longitudinal axis 17 of the lever 16, as is shown in FIG. 1.
  • the two sliding surface elements 20, 21 are pressed together by means of a tension spring 30 which is located between the upper end of the bearing body 2 and a fastening pin 31 attached to the housing 1.
  • a pivoting movement applied to the lever 16 by the guide curve arrangement 4, 5 via the cam follower roller 18 is converted into a linear movement of the lever 16, the sliding surface element 20 sliding along the sliding surface element 21 set at the angle ⁇ .
  • This enables a relief grinding movement of the workpiece, in particular a tap, which is in engagement with the grinding wheel 10 and which consists exclusively of a movement in the direction of the longitudinal axis of the lever 16, the lever arm of which corresponds to the distance between the axes 3 and 7.
  • the size of the relief grinding movement can be changed by changing the angle a. Movement from the angular position shown in FIG. 1 in the clockwise direction reduces the relief value, movement in the counterclockwise direction increases the relief value.
  • a measuring and heating element 32 connected to the control unit 28 is arranged inside the lever 16 in order to monitor the length of the lever 16 and the position of the longitudinal central axis 17 of the lever 16.
  • the measuring and heating element 32 can thus have an influence on the diameter of the workpiece when it is being processed by the grinding wheel 10. If the lever z. B. at an operating temperature of 60 ° C has a certain length, this can be increased by heating the heating element 32 continuously and extremely finely in the desired manner when the heating element 32 is heated. This can consist of a heating coil, for example.
  • the length can be measured, for example, using strain gauges.
  • the position of the longitudinal central axis 17 of the lever 16 can take place via angular position sensors. This enables a fine adjustment in the ⁇ range.
