Definitions

  • the invention is based on a hand planer according to the Genus of claim 1.
  • a hand planer is known from EP 0 048 303, whose planer knife fixed on the knife shaft with jaws become.
  • the planer knives are in this hand planer Assembled with great effort, but after disassembly of the planing knife by the user the original Position accuracy not again or only with great Effort is achievable.
  • Blunt planing knives therefore reground without disassembly. They are only allowed to do so can be sharpened with a minimal abrasion because with high grinding abrasion, the knife edge is too radial is shifted inwards opposite the knife shaft and none Chip removal is more possible.
  • planer shafts are at the latest in the final assembly together with the planer knife installed balanced with a firmly screwed jaw. If after the first knife change or regrinding the jaw does not return to its original position, increases the unbalance and leads to vibrations which are all the more disturbing the lighter the hand tool is.
  • features of claim 1 have the advantage that the planing knives and the Jaws always reproducible in the original position are adjustable and that there is therefore no vibration comes when operating the hand planer.
  • the one with the hand planer achievable work quality is across their entire Lifespan consistently high.
  • the plane shaft bearings are less stressed and therefore have a longer service life than previously known planes.
  • a hand planer consisting of a basic body on at least one Flattening over the contour of the base body with its Knife edge protruding planing knife that over a Clamping jaw is clamped to the base body, the clamping jaw by means of at least one clamping screw with the base body is screwed, adjusting the planing knife on the Knife shaft, especially after sharpening the planing knife, is cumbersome and time consuming.
  • FIG. 1 shows a side view of a hand plane
  • FIG 2 the cross section of a knife shaft of this hand plane
  • Figure 3 is a top view of the knife shaft
  • Figure 4 is a spatial representation of a clamping jaw of the plane shaft
  • Figure 5 is a plan view of the jaw
  • Figure 6 is a Clamping screw for fastening the clamping jaw on the knife shaft
  • Figure 7 is an enlargement of the contour of the screw shaft the clamping screw according to Figure 5
  • Figure 8 is a lateral Sectional view of the jaw
  • Figure 9 a Enlargement of the screw hole profile according to FIG. 8.
  • a hand planer shown in Figure 1 in side view 10 consists of a machine housing 12 with a Motor housing 14 and a handle 16.
  • an electrical switch 18 is arranged in the handle 16 .
  • a knife shaft 20 is rotatably mounted about its axis 19, whose cutting 22 one when the knife shaft 20 rotates Determine dash-dot flight circle 24, the over the base surface of the hand planer designed as sole 26 10 protrudes so that the cutting 22 in engage a workpiece that is flush with the sole 26 can.
  • An opening 28 arranged in the sole 26 for The cutters 22 pass through a pendulum guard 30 lockable. This closes automatically as soon as the hand planer 10 is lifted off a workpiece.
  • FIG. 2 shows a cross section of the knife shaft 20, wherein a base body 32 can be seen, which is a mirror image a flattening 34 with a Has planer knife 36, of which only one side is fully designated. On the flattened side 34 Side of the planer knife 36 is by means of adjusting screws 40 an adjustment body 38 attached. The adjustment screws 40 engage in a threaded bore 42 in the planing knife 36.
  • the adjustment body 38 consists of an L-shaped, along the planer knife 36 extending sheet metal profile strip. A formed by a short leg, bent at right angles Tab 38 'of the adjustment body 38 engages in an adjustment groove 44 in the flattening 34 of the base body 32 and thus places the cutting edge 22 of the planing knife 36 or the Flight circle 24 fixed to the base body 32. Between the Head of the adjusting screw 40 and the adjusting body 38 is one Washer 46 arranged as a screw lock.
  • a clamping jaw 48 is radial by means of a clamping screw 50 screwed to the base body 32.
  • the clamping screw 50 passes through a screw hole 52 of the jaw 48 a tapered screw shaft 54.
  • the thread area of the Screw shaft 54 engages in a threaded bore 56 of the Base body 32 and holds the jaw 48 against loss sure firm.
  • the planing knife 36 is secured in position via the clamping jaw 48 stretched against the base body 32.
  • the top view of the jaw 48 shown in FIG. 3 according to FIG Figure 2 leaves a part of the base body 32, the depressions 58, 58 ', 58' ', the bases 60, 60', 60 '' and the clamping screw 50 the knife edge 22 of the planing knife 36 recognize.
  • the contour of the adjusting body is dash-dotted 38 and the adjusting screws 40.
  • the arrows x - x show the section of the representation of Figure 2.
  • the jaw shown as a detail in Figures 4, 5 48 clearly shows the cup-like depressions 58, 58 ', 58' ' and the square screw holes 52, 52 ', 52' 'in the Base areas 60, 60 ', 60' '.
  • FIG. 6 shows a clamping screw 50 as a detail, with its tapered shaft 54 immediately adjacent to the screw head 64 can be seen.
  • the diameter of the tapered screw shaft 54 is somewhat larger than the edge dimension of the square screw hole 52 or as that of the inner circle.
  • the first squared screw hole 52 '' with the assembly sequence number 1 according to Figures 3, 4, 5 is square and fixes the jaw 48 axially and tangentially to the Base body 32 by its edge dimension along and across Axis 19 of the plane shaft 20 is approximately 0.1 mm smaller than that The diameter of the screw shaft 62.
  • the second squared screw hole 52 with the assembly sequence number 2 in Viewing direction right outside, is square, parallel measured to axis 19, 0.2 mm larger than the diameter of the screw shaft 62 and secures the jaw 48 only in Circumferential direction and radially opposite the plane shaft 20.
  • Das has middle screw hole 52 'with the assembly sequence number 3 the same dimensions as the second screw hole 52, so that the effect is also identical.
  • FIG. 8 shows a clamping jaw 48, the base surfaces 60, 60 ', 60' 'of the depressions 58, 58', 58 '' slightly through Embossing are arched upwards so that they are integrated Disc spring act, which the screw preload after the Secure final assembly.
  • the magnification of the corresponding one shown in FIG 8 shows a section of the base area 60 according to FIG disc spring-like curvature of the base surface 60 with respect to one Tangent 66.
  • the area of the cup spring-like curvature is through carbonitriding Case hardened, resulting in a larger one possible travel and better glide the adjusting screw 40.
  • the remaining screw holes are like the second screw hole designed only as a tight fit slot according to Figure 8 or have play all around, so that the screw the Clamping jaw only clamps radially in the area of the screw hole.
  • the jaws are at least the two outer screw holes the jaws as polygonal, especially rectangular Elongated hole, with their longitudinal axes are arranged at right angles to each other.
  • Essential for the functioning of the present invention is the point contact between the screw shaft and the Screw hole edge, which practically only over a polygonal, especially square hole or a multiple interrupted Circular recess is feasible.
