Definitions

  • the invention relates to a hand planer with an arranged in the machine housing, fixed on a transverse to the planing direction, motor-driven tool shaft, essentially circular cylindrical planing tool, which has a freely facing outside on the facing side of the housing, which is pivoted upwards, on the housing arranged swivel hood is covered.
  • Such a planing machine is known from US-PS 31 26 929.
  • a recessed workpiece surface can be planed into the corner at the transition to the adjacent upstanding workpiece surface, as is the case, for example, with rebate planing is.
  • an object protrudes relatively far upwards, for example a guide rail for lateral guidance of the planing machine, hinders the laterally protruding one intended to protect the operator and the tool and when working upward swiveling swivel hood planing.
  • the present invention is therefore based on the object of improving the hand-held planing machine mentioned at the outset in such a way that the swivel hood does not hinder planing from any recessed areas into the corners.
  • pivoting hood in the upwardly pivoted state is at least by the amount that it protrudes beyond the housing side surface, axially displaceable towards the center of the housing.
  • a pivot shaft connected to the pivoting hood is rotatably mounted in a housing bore and is arranged axially displaceably.
  • the pivoting hood is expediently displaceable against the force of a spring and can be locked in the inner position.
  • Another expedient measure is that a return spring holding the swivel hood against a swivel stop is provided. This measure keeps the swivel hood in its lowest possible position.
  • the swivel hood or the swivel shaft to be connected to a radially projecting swivel lever which serves to carry out the swivel and / or axial movement.
  • This is expediently arranged in the region of a front handle on the housing, so that a hand grasping the handle can actuate the pivot lever with a finger.
  • a motor-driven tool shaft running transversely to the planing direction indicated by an arrow in FIG. 1 is mounted, onto which an essentially circular-cylindrical planing tool 16 is attached and fastened in a rotationally fixed manner.
  • the housing 10 is closed behind the planing tool 16 at the bottom by an outlet table plate 40, to which a bearing for the tool shaft can be integrally formed in the interior of the housing.
  • the underside of the outlet table top 40 is arranged tangentially to the flight circle of the planing tool 16, which is determined by two planing knives 41 which extend in the axial direction on opposite sides of the peripheral surface of the planing tool 16.
  • an inlet table top 57 which is parallel to the outlet table top 40 and adjustable in height is arranged at the bottom of the housing 10.
  • a housing recess 24 receiving the planing tool 16 is open to the outside. Accordingly, the outer end face of the planing tool 16 visible in FIG. 1 faces freely outward and lies in the plane of the housing side face 25. In this way, planing can be carried out into corners and edges with the hand planer, provided that the free end face of the planing tool 16 covering swivel hood 26 is swung away beforehand.
  • the free end face of the planing tool 16 can also be offset somewhat inwards or outwards with respect to the housing side surface 25, for which purpose the planing tool 16 itself or its tool shaft can be axially adjusted.
  • the drive of the tool shaft and its mounting is arranged on the side of the planing tool 16 opposite the free end face.
  • An axial screw 17 with a washer 18 is used to fasten the planing tool 16 to the tool shaft.
  • These are arranged in an end recess 19 in the planing tool 16 in order to avoid the screw 17 projecting beyond the free end face of the planing tool 16.
  • the swivel hood 26 can be swiveled upward about a swivel axis 42 running parallel to the tool shaft 11 (this means the geometrical axis line) and can be axially displaced towards the center of the housing by a certain amount. In this way, the housing side surface 25 can serve as a stop when planing along corners or edges, the planing tool being exposed for this purpose. 2, the swivel hood 26 is connected to a swivel shaft 50 which can be rotated about the swivel axis 42 and which is rotatably mounted in a corresponding housing bore 51.
  • the end of the pivot shaft 50 is supported by a spring 52 against the bottom of the bore 51, so that an axial movement of the pivot shaft 50 inwards against the force of this spring 52 must take place.
  • the bore 51 opens out into a chamber 53, in which a locking device consisting of two parts 54, 55 is arranged.
  • the part 54 can be locked behind the part 55.
  • Another spring 56 on the one hand on the wall of the chamber 53 and on the other hand connected to the pivot shaft 50, serves in the form of a torsion spring as a return spring for returning the pivot hood 26 to the position covering the planing tool 16.
  • the swivel hood can of course also be locked in the upper, axially inwardly pushed position by another locking device.
  • a swivel lever 43 is attached to the swivel hood 26 or to its swivel shaft perpendicular to the swivel axis 42.
  • An operator's hand comprising a front handle 44, can easily pivot the pivot lever 43 e.g. operate with the thumb.
  • this swivel lever 43 points upwards.
  • the swivel hood 26 can be moved to the upper position (shown by a solid line) by a downward movement of this swivel lever 43 and then be displaced somewhat inwards.
  • the swivel hood can of course also be locked in the upper, inwardly pushed position by other locking devices.
  • the pivoting hood 26 itself or the pivoting lever 43 can be locked in a corresponding slot or behind an edge.
  • a corresponding indentation in the housing 10 can serve here as a stop surface for the swivel hood 26 in the locked position or also in the case of other locking devices.
