Definitions

  • the invention relates to a grinding machine for processing the cutting of tools or the like, consisting of a machine frame with a vertical stand on which an electric motor and the grinding wheel which can be driven above it is adjustable in different directions, and a tool holder carrier plate which receives the tool holder arranged outside the stand on the machine frame and is also adjustable in different directions.
  • a grinding machine of this type is known from DE-OS 22 31 359.
  • the electric motor with the grinding wheel can be adjusted horizontally in a machine carrier.
  • the machine carrier itself is a hori zontal pivot axis adjustable on the stand, this pivot axis is perpendicular to the direction of adjustment of the electric motor and the grinding wheel in the machine frame.
  • the machine support is attached to a sleeve that can be rotated around the stand. In this way, the grinding wheel can be adjusted in all three directions.
  • the tool holder support plate is pivoted at the end of an arm. At the other end of this arm, another arm is articulated, which is rotatably mounted on a guide part.
  • the guide part can be pivoted about a vertical axis and can also be tilted on a slide.
  • This adjustment mechanism with further drive means which, in addition to a straight-line movement, also transmit the rotational movement to the tool holder carrier plate, so that a spiral or helical cutting edge can be ground, is on a basic slide and a further slide in two mutually perpendicular ones horizontal directions adjustable.
  • This known grinding machine has been specially developed for grinding tools with a spiral or helical cutting edge and is therefore very complicated in terms of effort and setting. It is therefore not suitable as a universal grinding machine on which the most varied of tools, such as drills, milling cutters or the like, can be easily ground with differently inclined cutting edges.
  • the electric motor with grinding wheel is attached to a horizontal slide, which is limited horizontally adjustable on a vertical slide in the direction from and to the tool holder support plate and can be fixed in selectable positions in that the vertical slide limits on the stand is vertically adjustable and can be fixed in selectable positions, that the tool holder support plate is pivotally mounted on a horizontally directed shaft and can be locked in selectable positions, that the shaft can be limited axially adjustable or can be fixed in selectable positions in a horizontal bearing holder, and that the bearing holder part is a turntable that is rotatable in the machine frame around a vertical axis of rotation through 360 ° and lockable in selectable angular positions.
  • the limitation of the adjustability of the grinding wheel in two directions precisely defined on the tool holder carrier plate is completely sufficient, since the tool holder carrier plate is adjustable in all three directions and moreover allows a predetermined grinding movement relative to the grinding wheel, the setting values being maintained in all three directions will.
  • the adjustment mechanism for the tool holder carrier plate remains very simple with the shaft, the bearing holder and the turntable. Join in only the locking device to be able to set the set positions. Since the stand with the horizontal and vertical slides always occupies the same position with respect to the axis of rotation of the turntable, all setting values are also in a fixed relationship to one another, which facilitates the setting for a wide variety of tools.
  • a wide variety of tool holders can also be attached to the tool holder carrier plate. With this configuration, a universally applicable grinding machine is created which can be quickly and easily adjusted to the cutting edge of the tool to be ground.
  • the coordinates of displacement of the two carriages is made possible in that the horizontal slide and the vertical slide in a known manner are adjustable by means of adjusting spindles, which are rotatable by means of winches and by means of A rret istsschrauben fixed.
