Definitions

  • the invention relates to a hand planer with a rotating knife carrier according to the preamble of claim 1.
  • the knife carrier of the well-known hand planer is for holding high-speed steel planer knives, which are wider and standard are higher than carbide-reversible planer knives, because high-speed planer knives do not have a groove on their back facing the cover shell, but on the opposite side, i.e. on their base surface.
  • high-speed steel planer knives other knife carriers or clamping devices are known, on which the planer knives can be slidably held without a pressure plate by means of adjusting screws which engage in the groove.
  • these knife carriers are not suitable for holding carbide planing knives.
  • the known hand planers can therefore only be used with a single type of planer knife, i.e. either with carbide-reversible planer knives or with high-speed steel reversible planer knives. This significantly limits the possible uses of the known hand planers.
  • the apparently simplest way would be to match the shape of the high-speed steel planer knife to that of the carbide-reversible planer knife, for example by molding a groove in the back, the groove being that of the Carbide-reversible planer knife would have to be the same size and there would be a considerable risk of confusion between the two planer knife types.
  • the hand planer according to the invention with the characterizing features of claim 1 has the advantage that two types of standardized planing knives, in particular carbide and high-speed steel reversible planing knives, can be attached to the knife carrier without separate holding means to be carried outside the hand planing machine.
  • FIG. 1 shows a side view of a hand planing machine in which the position of the planing knives can be seen
  • FIG. 2 shows a side view of a knife holder with carbide-reversible planer knives
  • FIG. 3 shows a side view of a knife holder with high-speed steel reversing planer knives
  • FIG. 4 shows a plan view of a pressure plate mounted on the knife carrier.
  • FIG. 1 shows a hand planer 1 with a handle 3, which carries an on and off switch 5 and which is part of the machine housing 7. Under a cover shell 9 there is a motor, not shown in detail, which rotates a knife carrier 11 shown in dashed lines. On two opposite sides of the lateral surface of the roller-like knife carrier 11, two planing knives 13, 15 are seated with cutting edges, which are not specified, and which are clamped on the knife carrier 11 by means not shown in detail.
  • FIG. 2 a sectional view of the knife carrier 11 shows a base body 17 which corresponds to a roller flattened on two opposite sides of its circumference.
  • Two identical plate sides 19, 21 each carry the same carbide-reversing planer knife 23, 25, which protrude beyond the circumference of the base body 17 with their cutting edges, which are not described in any more detail.
  • Each of the two planing knives 23, 25 is held by one of two identical pressure plates 35, 37 relative to the base body 17.
  • the carbide-reversible planing knives 23, 25 each have a groove 27, 29 on their sides facing away from the plate sides 21, 29. Noses 31, 33 of two pressure plates 35, 37, which are identical to one another, project into these On the side of the pressure plates 35, 37, two mutually identical cover shells 39, 41 are supported, each with an unspecified end-face clamping surface, and in this way press the carbide-reversible planing knives 23, 25 secured against displacement against the plate sides 19, 21 of the base body 17
  • the cover shells 39, 41 are supported on the plate sides 19 by a respective second clamping surface opposite the end clamping surface - pulled by a clamping screw 43, 45 screwed to the base body 17 and passing through the cover shells 39, 41 and the pressure plates 35, 37 , 21.
  • Two stops 47, 49 arranged on the pressure plates 35, 37 pass through recesses in the base body 17, which are not identified in any more detail, and are towards the outer shells 39, 41 facing away.
  • the stops 47, 49 are two adjusting screws 51, 53 assigned, which take the pressure plates 35, 37 with them when they are unscrewed.
  • Two further mutually identical stops 48, 50 are functionally the same as the stops 47, 49 - just as the two further lugs 32, 34 are the same as the lugs 31, 33 - but with a changed position of the pressure plates 35, 37 and when using differently designed ones Planer knife. This is explained below with reference to FIG. 3.
  • FIG. 3 differs from the embodiment of Figure 2 only in that high-speed steel planer knives 24, 26 are arranged instead of the carbide-reversible planer knives and by the changed position of the pressure plates 35, 37 and the arrangement of wedge-shaped washers under the clamping screws 43, 45.
  • the reference numerals have therefore been retained for the elements corresponding to FIG. 2.
  • the knife carrier 11 consists of a base body 17 which corresponds to a roller flattened on two opposite sides of its circumference.
  • the two identical plate sides 19, 21 each carry the same high-speed steel planer knife 24, 26. These protrude with their unspecified cutting edges over the circumference of the base body 17.
  • the two planer knives 24, 26 are the same as a washer by the two acting pressure plates 35, 37 held relative to the base body 17 and overlap with their grooves 28, 30 the lugs 32, 34 of the pressure plates 35, 37.
  • the two support each other the same Cover shells 39, 41, each with an unspecified end clamping surface and in this way press the planing knives 24, 26 secured against displacement against the pressure plates 35, 37.
  • the two stops 48, 50 pass through unspecified Recesses in the base body 17 and are each directed to the side facing away from the cover shells 39, 41.
  • the stops 47, 49 are assigned two adjusting screws 51, 53, which take the pressure plates 35, 37 with them when they are unscrewed.
  • stops 48, 50 facing the cover shells 39, 41 which have no recognizable function according to FIG. 2, serve as adjusting means by turning the pressure plates 35, 37, and that the stops 47 in FIG. 49 in the turned position according to FIG. 3 until the possible turning again for receiving carbide-reversing planing knives instead of the high-speed steel reversing planing knives 24, 26 have no function.
  • the pressure plates 35, 37 can be brought into alternating holding positions by turning, in which they can alternatively use high-speed steel planing knives 24, 26 or carbide-reversing planing knives 23, 25 on their serving as a holding surface Hold the base or back surface in a form-fitting manner.
  • the pressure plates 35, 37 belong to the basic equipment of the hand planing machines and are therefore always available, so that either high-speed steel or carbide-reversible planing knives 24, 26, 23, 25 can be clamped equally adjustable if necessary or depending on the availability. With the cover shells 39, 41, both types of planing knives can be clamped with the same degree of security without any special adaptation.
  • the carbide-reversible planer knives 23, 25 are assembled and adjusted in the following way: After placing the carbide-reversible planing knives 23, 25 on the plate sides 19, 21 of the base body 17 and placing the pressure plates 35, 37 and subsequent fastening of the cover shells 39, 41 by means of the tensioning screws 43, 45 on the base body 17, the carbide-reversing planer knives 23, 25 are adjusted by turning the adjusting screws 51, 53 so that the flight circle of the cutting edges of the carbide Reversible planer knives 23, 25 are arranged on predetermined coordinates with respect to the axis of rotation of the base body 17 and good cutting performance can be achieved. The carbide-reversible planer knives 23, 25 are moved into the desired position by being carried over the pressure plates 35, 37 via the stops 47, 49. After adjustment, the clamping screws 43, 45 are turned to the prescribed clamping torque.
  • the high-speed steel planer knives 24, 26 are assembled and adjusted in the following way: After placing the pressure plates 35, 37 on the plate sides 19, 21 of the base body 17 and placing the high-speed steel planer blades 24, 26 and then fastening the cover shells 39, 41 by means of the clamping screws 43, 45 on the base body 17, the high-speed steel Turning planer knives 24, 26 are adjusted by turning the adjusting screws 51, 53 so that the flight circle of the cutting edges (not shown) of the planing knives 24, 26 are arranged at predetermined coordinates with respect to the axis of rotation of the base body 17 and good cutting performance can be achieved. The high-speed steel planer knives 24, 26 are moved into the desired position by being carried over the pressure plates 35, 37 via the stops 48, 50. After adjustment, the clamping screws 43, 45 are turned to the prescribed clamping torque, the inclined position of the cover shells 39, 41 being compensated for by wedge-shaped washers, which are not described in any more detail.
  • the top view of one of the pressure plates 35 or 37 shown in FIG. 4 shows the edges of the lugs 31 or 33 and 32 or 34 and the stops 47 or 49 and 48 or 50 and openings 55 designed as elongated holes.
