Definitions

  • the present invention relates to an oscillation drive with a tool according to the preamble of claim 1.
  • An oscillation drive is to be understood as meaning a drive whose output shaft executes an oscillating rotational movement during operation.
  • a fixed to the output shaft tool can be used in a variety of ways, such as for sawing, cutting or grinding.
  • a first variant the tool is pressed with a clamping element, for example by means of a clamping screw, against a receptacle at the free end of the output shaft, so that a high frictional force between the tool and the recording arises.
  • a clamping element for example by means of a clamping screw
  • Such a connection is referred to as frictional.
  • the receptacle or the tool on a mounting portion which can engage in a correspondingly shaped mounting opening on the other part.
  • the transmission of the torque is achieved here by a form fit between the mounting portion and mounting hole.
  • a positive connection offers over a frictional connection the advantage that even very high torques can be transmitted.
  • the attachment portion widens in a direction parallel to the longitudinal axis and on the contact surface at least in one area.
  • the width of the attachment portion is determined in a plane perpendicular to the longitudinal axis and measured along a circular arc whose center lies on the longitudinal axis.
  • the broadening of the attachment portion in the direction of the contact surface can thus be described such that the width of the Fastening portion in a first plane perpendicular to the longitudinal axis is greater than the width in a parallel plane which is farther away from the abutment surface than the first plane.
  • attachment portion narrows or tapers in at least one region away from the contact surface in one direction.
  • base surface of the fastening section, with which the fastening section rests on the contact surface is larger than the surface of the fastening section facing away from the base surface. If the surfaces mentioned are not flat, the respective surface dimension is to be considered in relation to a plane perpendicular to the longitudinal axis.
  • the attachment portion has a plurality of protrusions protruding radially outward with respect to the longitudinal axis.
  • the oscillation drive according to the invention combines the advantages of a positive connection, namely the possibility of transmitting high torques, with the advantages of a frictional connection, namely that overloads are avoided.
  • the transmission of the torque takes place in principle positive fit by a positive connection between the mounting portion of the output shaft and the mounting opening of the tool.
  • the oscillation drive according to the invention allows a certain axial deflection of the tool with respect to the longitudinal axis of the output shaft. Due to the axial deflection of the tool, the tool moves into a region of the mounting portion, which allows a rotation of the tool by a certain angle of rotation.
  • the fastening means presses the tool back into its form-fitting starting position.
  • the force which opposes the fastening means of the axial displacement of the tool is achieved in that the fastening means has an elastic and / or resilient part or is elastically and / or resiliently received.
  • the fastener elastically and / or resiliently presses against the tool and holds it in positive fit.
  • the tool presses against the force exerted by the fastener, so that in a sense a part of the force acting on the attachment portion against the force Fastener is passed.
  • the axial deflection of the tool increases the force exerted by the fastener force and pushes the tool back into the secure positive fit as soon as the increased load decreases.
  • each projection forms, starting from the contact surface, at least one flank whose base line on the contact surface is essentially straight.
  • a corresponding contact surface should also be formed with a straight base line at the attachment opening of the tool. Then the torque transmission can take place along the entire straight line. This can eliminate punctiform stresses between the fastener and the mounting hole, so that areas with a particularly high heat load can be avoided.
  • the flank to the longitudinal axis forms an angle between 5 ° and 40 °, preferably between 10 ° and 25 °, in particular between 13 ° and 17 °.
  • the angle can be chosen in view of the intended material pairing, e.g. Steel on steel or steel on aluminum.
  • the surface of the flank forms a flat trapezoid.
  • the surface of the flank is designed in such a way, upon rotation of the tool a particularly good sliding of the part of the fastening opening corresponding to this flank is possible. Furthermore, it is advantageous in this embodiment that the sliding of the part of the fastening opening and thus the axial deflection of the tool is approximately proportional to the force acting on the tool in the plane of oscillation. That is, the higher the load on the tool, the further the tool can yield axially.
  • the output shaft on a biased by a spring element tension element on which the fastening means can be fixed.
  • the fastening means for example, a fastening pin, held by the substantially rigid tension member, wherein the tension member is in turn held by means of the spring element resiliently in the oscillation drive.
  • the principle of such a structure is for example from the DE 39 02 874 A1 known.
  • the fastening means on an elastic and / or resilient portion.
  • the tool is held by a member that allows the axial deflection of the tool due to a partially elastic and / or resilient property.
  • a fastening means can for example represent a clamping screw whose screw head has a certain elasticity or is elastically displaceable with respect to the screw shaft.
  • the attachment portion is polygonal in cross-section, preferably formed hexagonal.
  • the projections are symmetrical with respect to a direction radial to the longitudinal axis and each have two flanks, which are connected to each other via a remote from the longitudinal axis, common, curved portion.
  • flanks approach at an angle between 5 ° and 35 °, preferably between 10 ° and 25 °, in particular between 12 ° and 18 °.
  • flanks of the projections are closed in an area near the longitudinal axis by an undercut.
  • the torque transmission does not take place in the innermost region of the projection, which is seen radially from the longitudinal axis, but in its middle, and possibly also in its outer region.
  • Fig. 1a shows an oscillating drive 10 with an output shaft 12 which is driven to oscillate about its longitudinal axis 14 and has a free end 16.
  • a receptacle 18 is arranged, which has a contact surface 20 for engaging a tool 22 (FIG. Fig. 3 ) having.

  • On the tension element 31 may be a fastening means 28 approximately in the form of a screw to be fastened, which passes through a fastening opening 26 of a tool 22 placed on the fastening section 24.
  • the tension element 31 In the rest position, the tension element 31 is pushed axially outwardly by the tensioning lever 30, so that in this position the fastening means 28 can be released without the aid of a hand tool in order to change the tool 22.
  • the tension element 31 reaches the working position, in which now the tension element 31 is stretched by the action of a spring element 32, so that the fastening means 28 and thus the tool 22 under the action of the spring member 32 against the contact surface 20 of the recording 18 is biased.
  • the fastening means 28 is here indicated in the form of a pin 34 inserted into the tension element 31 with a head 35.
  • the resilient attachment of the fastener 28 results in that the fastener 28 can also be displaced against the force exerted by the spring element 30, i. away from the contact surface 20, when a correspondingly large force is exerted on the fastening means 28.
  • either the tension element 31 or the attachment means 28 permits axial deflection of the tool 22.
  • the force required to counteract the pretension of the attachment means 28 results from FIG between the output shaft 12 and the tool 22 acting torque, as will be explained in more detail below.
  • the attachment portion 24 here has four projections 36, which are each arranged at an angle of 90 ° to each other about the longitudinal axis 14. (One of the projections 36 is hidden here.) The projections 36 are each connected via a concentric to the longitudinal axis 14 arc-like portion 44. Overall, it should be noted that the attachment portion 24 widens in a direction parallel to the longitudinal axis 14 and on the contact surface 20.
  • the projections 36 are symmetrical with respect to a radial direction to the longitudinal axis 14 and each have two flanks 38, which facing away from the longitudinal axis 14 , common, curved portion 42 are interconnected.

  • the flanks 38 form in a side view approximately according to Fig. 1a, b each a flat harness.
  • the angle ⁇ formed by a flank 38 to the longitudinal axis 14 is here about 15 °.
  • the angle ⁇ at the rounding of the projection 36 is here also about 15 °, but if necessary, it can also be selected differently from the angle ⁇ .
  • the projection 36 tapers in the radial direction from the longitudinal axis 14 to the outside.
  • the taper is achieved by the planar flanks 38 approaching radially outward.
  • the angle ⁇ between the two flat flanks 38 is approximately 15 ° here.
  • flanks 38 of the projections 36 in an area close to the longitudinal axis 14 are each closed by an undercut 46. This can cause the power transmission between the output shaft 12 and the tool 22 takes place mainly or exclusively along the flanks 38.
  • Fig. 3 shows the oscillating drive 10 with attached tool 22.
  • the mounting hole 26 has eight receptacles, the shape and size of the projections 36 is adapted so that the tool 22 - as shown by the dashed line - can be placed in different positions.
