Definitions

  • the invention relates to a power tool with a work spindle for driving a tool, wherein the tool between a holding portion on a tool-side end of the work spindle and a fastener is fixed, with a displacement device for displacement of the fastener between a release position in which the fastener of the work spindle solvable, and a clamping position, in which the fastening element is clamped against the holding portion by a spring element, wherein the fastening element has an insertable into the work spindle clamping shaft which is held in the clamping position by a closure within the work spindle and is removable in the release position.
  • Such a power-operated hand tool is from the DE-A-41 22 320 known.
  • the work spindle is designed as a hollow spindle into which a clamping element can be screwed, through which a grinding wheel can be clamped.
  • the clamping element is biased in the clamping position by a plate spring package.
  • the disc spring assembly can be relieved, so that the clamping element can be unscrewed in a release position.
  • Another power-driven hand tool with a clamping device for manual clamping of a tool is from the EP 0 152 564 B1 known.
  • an angle grinder having a hollow drive shaft formed with a displaceably mounted therein spindle, which is displaceable by means of a clamping device between a clamping position and a release position.
  • a clamping device In the clamping position, a tool, for example.
  • a grinding wheel clamped by a nut against a mounting portion and held by moving the clamping device in the clamping position under spring force. Since the displacement device in the release position causes a displacement of the spindle against the force of a spring, the nut can be unscrewed in the release position without the aid of a tool to change the tool.
  • Such a clamping device basically allows tool-free clamping of a tool on the drive shaft of a hand tool, however, such a clamping device is only suitable for clamping of rotationally driven tools. If, on the other hand, the tool is reciprocally driven by an oscillation drive about the longitudinal axis of the work spindle, then large, impact-like torques result in both directions of rotation with high dynamics, so that with the known tensioning device no sufficiently secure clamping of the tool can be guaranteed.
  • Another power-driven hand tool that has an oscillating driven work spindle for driving the tool, wherein the tool on the work spindle between a holding portion of the work spindle and a mounting flange is fixed, which is rigidly connected to a clamping anchor.
  • the clamping anchor can by means of a collet-like clamping action, by means of a spring ring or O-ring, be held by magnetic force or by means of a spring-loaded rolling body lock on the work spindle.
  • the invention is therefore an object of the invention to provide a power tool, which allows attachment of a tool to the work spindle in a simple and reliable manner, without the need for an auxiliary tool, such as a wrench or the like must be used. This is a high clamping force to be achieved, which is sufficient to ensure a reliable and safe voltage of the tool even with heavy loads, such as those occurring in oscillating driven devices.
  • the displacement device allows a complete decoupling between the application of the clamping force by the spring element and between the movement of the work spindle.
  • the spring element of which the clamping force is applied, moves together with the work spindle, so that by a corresponding dimensioning of the spring element, a high clamping force can be applied.
  • the closure for fixing the insertable into the work spindle clamping shaft is received within the work spindle itself, it is also possible to decouple the displacement device completely from the work spindle, so that in the clamping position no contact between Work spindle and displacement device consists. In this way, frictional forces are avoided and a release of the tension is prevented even with strong, jerky and oscillating loads.
  • the radially movable on the sleeve clamps a particularly high clamping force is ensured.
  • form-locking elements are provided on the clamping shank of the fastening element and on the closure for the positive fixing of the clamping shank in the clamping position.

  • the clamping pieces of which preferably three or more clamping pieces are provided at equal angular intervals to each other, are preferably held in recesses of the sleeve.
  • the clamping pieces on their side facing the tool on inclined surfaces which cooperate with inclined surfaces of the sleeve such that a movement of the sleeve against the inclined surfaces of the clamping pieces causes an application of the clamping pieces towards the center.
  • the sleeve is expediently biased by the spring element in the axial direction in the direction of the closed position.
  • an ejector in the form of a rigidly fixed to the work spindle sleeve is provided on the work spindle, which limits a movement of the clamping pieces in the axial direction of the tool.
  • the clamping pieces are secured by lugs against falling out of the sleeve towards the middle.
  • the work spindle on a spindle tube and a bearing pin which are fixedly connected to each other, preferably screwed together, and which define a cavity within which the closure and preferably the spring element are received.
  • the bearing pin is penetrated in the axial direction by a pressure piece over which the closure against the force of the spring element is axially displaceable.
  • the displacement device preferably has an actuatable by means of a clamping lever eccentric, which acts on an axial end of the pressure piece.
  • the eccentric is designed so self-locking that an automatic movement of the clamping lever from the release position is prevented in the clamping position.
  • the pressure piece is kept limited in a preferred embodiment of the invention in the clamping position by the bearing pin in an end position in which the displacement device maintains an axial distance from the pressure piece.
  • the pressure piece is preferably screwed to the sleeve.
  • the clamping pieces are preferably enclosed by a clamping element, preferably in the form of an O-ring or the like on their outer surfaces and biased towards the center.
  • the work spindle is preferably coupled to an oscillating drive for oscillating drive about its longitudinal axis.
  • the work spindle may be connected to a tuning fork, which cooperates with an eccentric for oscillating drive of the work spindle.
  • the spring element should preferably be dimensioned such that a high clamping force results, which is sufficient for all applications.
  • the spring element can be designed as a helical spring, as a plate spring or as a different kind of spring, for example as a rubber spring.
  • a toothed section is preferably provided on the clamping shaft of the fastening element, which cooperates with an associated toothing on the clamping pieces.

  • Each clamping piece 62 has on its side facing the pressure piece 50 an axial bore 65, within which a spring 64 is received, which may be formed approximately as a spiral spring and which serves a pressure of the clamping pieces 62 in the direction of the tool 68.
