Definitions

  • the invention relates to a motor-driven machine tool, in particular a hand-held machine tool, according to the preamble of claim 1.
  • Pendelhub too is at best to a limited extent possible in the straight-ahead working direction rotated about its longitudinal axis working tool.
  • the invention is based on the object to simplify a motor-driven machine tool of the type mentioned in construction, robust design and in particular to the effect that, if necessary, a pendulum lifting operation in the direction of the longitudinal axis from its straight working direction twisted working plane of the working tool, ie a " scrolling "working mode is possible.
  • Supporting the working tool on the support member is rotational position independent. This makes it possible to simplify the guidance for the lifting rod and to form it by a sliding guide running in the lifting direction, which in turn is supported on the supporting frame via a pivot axis running transversely to the working plane.
  • this support is provided on the support frame at its end region remote from the working tool, then it is possible to rigidly form the lifting rod, starting from the working tool or the receptacle for the working tool up to the support comprising the sliding guide, and into the
  • Lifting rod near the support to integrate the drive connection to the lifting drive resulting in a very compact design and especially in the field of drive connection to the lifting drive at pendulum driven working tool in the direction of the working plane brings only small pivoting with it, which simplifies the design of the drive connection.
  • crank drive equipped as an eccentric drive and includes an eccentric pin supported by a housing side mounted drive wheel, which engages in the guide slot of a link part, wherein the Sliding part extends transversely to the working plane of the working tool and the eccentric engages in the slotted guide.
  • the link part of the lifting rod is integrally connected to the rotatably guided in the sliding guide in the direction of the longitudinal axis part of the lifting rod, so that this part of the lifting rod may preferably consist of flat material, for example, may be formed by a stamped part.
  • the lifting rod is formed in its section extending from the slide part to the tool holder with a rigid connection to the slide part by a round material, in particular a rod-shaped round material, so that with conventional
  • Tool holders can be worked.
  • the support of the support member to the support frame is provided against the cage-like support frame provided, downwardly projecting support legs via a transverse plane to the work plane pivot axis, wherein the support member preferably as
  • Angular lever is designed, which is provided projecting over its leg remote from the working tool with a setting sector, which is within the allowable range of rotation of the support frame in the overlap region to the a- xial preferably parallel to the longitudinal axis adjustable actuator which acts on the actuator for the pendulum movement of the working tool is.
  • Fig. 1 is a perspective and schematic overall view of a
  • Jig saw designed machine tool according to the invention redu- graces the parts essential for the understanding of the invention and in particular largely without housing parts, and
  • FIG. 2 to 4 representations of the machine tool of FIG. 1 in frontal view, side view and plan view, partly simplified.
  • the machine tool 1 shown in the figures is designed as a jigsaw 2, the working tool 3 is formed by a liftable driven saw blade 4.
  • the saw blade 4 is connected via a saw blade holder 5 to the lifting rod 6 acted upon by a lifting drive 7.
  • the intended as a working tool 3 saw blade 4 has a longitudinal axis 8, which lies in the working plane of the saw blade 4, the front side has a toothing 9 and against the opposite saw blade back 10, a support member 1 1 is supported via a support roller 12.
  • the support member 1 1 is as
  • Swivel lever 13 is formed, which is articulated via a pivot axis 14 on a support frame 15.
  • the support frame 15 has a cage-like training on an upper in the drawing, remote from the working tool 3 support ring 16 and a lower support ring 17, which are connected by a longitudinal strut 18, veranerie by a longitudinal strut, fixed in position. From the lower support ring collar in the drawing down support legs 19, which are penetrated by the pivot axis 14.
  • a plate-shaped actuating sector 20 is provided, which is acted upon by the control element 21 provided for the pendulum drive, positionally fixed actuator 22.
  • the support frame 15 is rotatably supported via at least one of its support rings 16, 17 for only schematically indicated housing 24 via a bearing, which is symbolically illustrated by a bearing supporting the upper support ring 16 bearing 25.
  • the lifting rod 6, which preferably contains in its upper, the upper support ring 16 adjacent portion the hubstangenseiti- gene drive part of the lifting drive 7, which as a gate member 26 is a transversely to the Working plane extending link guide 27 has, in which an eccentric pin 28 engages, which is provided on a drive wheel 29 of the eccentric drive designed as a crank mechanism 30 and part of the lifting drive 7.
  • the lifting rod 6 continues with a section 31, which passes through a sliding guide 32, which is part of a transverse to the working plane extending strut 33, which extends over a likewise transverse to the working plane pivot axis 34 for upper support ring 16 is rotatably supported.
  • the slide member 26 comprehensive portion 31 of the lifting rod 6 is rotatably connected via the sliding guide 32 and slidably connected in the direction of the longitudinal axis 8 with the strut 33, which in turn is pivotable about the pivot axis 34, so that for the lifting rod 6, the one over its length continuous rigid unit forms, a pivot bearing is provided about the pivot axis 34, the lifting rod 6 is movable in the extension provided with saw blade 4 on the support member 1 1 when acted upon by the actuator 22.
  • the upper portion 31 of the lifting rod 6, which contains the slide member 26 is preferably made of flat material, can accordingly also be inexpensively formed as a stamped part and goes down into a circular cross-section rod member 35, which is fixedly connected to the gate member 26 and on the the saw blade holder 5 is provided.
  • the described construction further offers the possibility of providing the lower support ring 17 with a sliding guide for the lifting rod 6 in the direction of its working plane, so that a transverse guide for the lifting rod 6 is also provided in the region of the lower support ring 17. This can be achieved, for example, by a bottom to the lower support ring 17, which has a corresponding, the lifting rod 6 with its rod member 35 leader receiving slot-shaped recess.

  • the rotational adjustment which is not shown, can take place directly by the attack of a rotary drive on the support frame 15, or indirectly via a rotary drive acting on the lifting rod 6, in particular its section 31.
  • the described structure of the jigsaw 2 leads to a very compact and robust design, in which the working tool is supported in the form of the saw blade in all rotational positions on the support member 1 1 in the respective working plane, so that even in deviating from the straight-ahead working directions a support of the Saw blade 4 is given on the support member 1 1 in the working plane, whereby the jigsaw 2 in the so-called scrolling mode, ie as a scrolling Jig Saw with superimposed to the lifting drive oscillating with in the direction of the saw blade plane 4 is to be operated.
  • the rotary drive for the lifting rod 6 is symbolically indicated by an arrow and designated 36.
