Definitions

  • a surface grinder is suitable for this purpose, but one must take measures to prevent pills from being ground in by the rotating grinding wheel.
  • the workpiece clamping device is rotatably mounted and driven by a motor. This way you have the besides the rotation of the grinding wheel additional rotation of the workpiece.
  • the axis of rotation of the workpiece grinder is expediently arranged parallel to the drive axis of the grinding wheel.
  • the workpiece clamping device can be pivoted and locked according to a further feature of the invention about a position arranged transversely to its axis of rotation. It is particularly expedient if the workpiece scanning device is designed in the manner of the tool holder of a punching machine.
  • a grinding process that is as largely automated as possible is preferred for such a grinding machine.
  • a control device is provided for the infeed of the grinding wheel, which is connected to a scanning element for the surface to be ground. It is then only necessary to place the scanning element on the surface to be ground, whereupon the grinding wheel automatically adjusts to the workpiece.
  • the control device expediently consists of a guide member which supports the grinding wheel or its carrier on a control cam.
  • the scanning element used is a scanning lever which is pivotably mounted on the guide element and can be pivoted into the working area of the grinding wheel and by means of which the guide element can be fixed on the carrier of the grinding wheel.
  • the guide member is rotatably and longitudinally displaceably mounted in a clamping sleeve connected to the scanning lever, which in turn is rotatably but non-displaceably connected to the carrier of the grinding wheel, the position pivoted out of the working area of the grinding wheel being the clamp-free and the pivoted-in position of the scanning lever the clamping function of the sleeve is assigned.
  • the control curve expediently has two sections, namely a section with a steep slope, which corresponds to the distance of the grinding wheel from the underside of the scanning lever, and one with a flat slope for the working movement.
  • the control cam is expediently shifted relative to the control member by a hydraulic feed device.
  • the surface grinding machine consists of a base frame 5 in which two guide columns 4 are connected, which are connected to one another by a head 6.
  • a Klertmmhülse 26 is non-displaceably, but rotatably mounted in the carrier 3, wherein it can be pivoted by means of a scanning lever 21.
  • a guide member 24 is also rotatable, but additionally longitudinally displaceable, in the clamping sleeve 26. This has a guide roller 25 at its lower end, which is supported on a control cam 23 and is pressed against it by means of a spring 2 °.
  • the control cam 23 can be displaced with respect to the guide member 24 by a hydraulic feed device 27.
  • a fin clamping device 11 is rotatably mounted with its axis 19 in a drive 20, the axis 19 running parallel to the axis 8 of the grinding wheel 2 at a distance.
  • the chuck 11 is in turn provided with a plate 12 which. is pivotally mounted in receiving bores 13.
  • a support screw 18 is provided which pushes a cylinder 17 under the plate 12 until the desired angular position of this plate is reached.
  • an impression screw 16 is provided.
  • the scanning lever 21 is first pivoted into the working area of the grinding wheel 2 and the carrier 3 is moved downwards until the scanning lever 21 rests on the workpiece 9. Then the scanning lever 21 is pivoted out of the work area. He takes the clamping sleeve 26 with him and moves it into its clamping position, so that the guide member 24 is firmly connected to the carrier 3.
  • the control cam 23 is provided with a steeply falling section 29, which corresponds to the distance between the grinding wheel 2 and the underside of the scanning lever 21.
  • the Schlefin 2 will thus rapidly lowered to the surface to be ground, whereupon, a flatter slope of portion 30 follows that of the normal Häbewe- gun corresponds g.
  • the fin clamping device 11 rotates so that the undesired grinding in of grooves or the like does not occur.
  • the scanning lever is pivoted back into the working area of the grinding wheel 2, the flush sleeve 26 loosening and the guide member 24 being released for re-adjustment.
