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, since high-speed planer knives do not have a groove on their back facing the cover shell, but on the opposite side, that is to say on their base surface.
- the known hand planer machines 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 hard metal reversible planer knife, for example by molding a groove in the back thereof, whereby the groove of the carbide-reversible planer knife would have to be of 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 planer knives, in particular carbide and high-speed steel reversible planer knives, can be attached to the knife carrier without separate holding means to be carried outside the hand planer .
- 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 planing knives
- FIG. 3 shows a side view of a knife holder with chord 11 steel reversible height knives
- FIG. 4 a plan view of a pressure plate mounted on the knife carrier.
- FIG. 1 shows a hand planer Machine 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-reversible planing knife 23, 25, which protrude beyond the circumference of the base body 17 with their cutting edges, which are not described in 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 flat sides 21, 29. Noses 31, 33 of two pressure plates 35, 37, which are identical to one another, project into these. 33 facing away from the side of the pressure plates 35, 37 are supported by two identical cover shells 39, 41, each with an end clamping surface (not shown), 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.
- 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 different position of the pressure plates 35, 37 and when used differently designed planer knife. This is explained below with reference to FIG. 3.
- FIG. 3 differs from the exemplary embodiment in FIG. 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 wedge-shaped arrangement 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 mutually the two same pressure plates 27, 29, which act as washers, are held against the base body 17 and overlap with their grooves 28, 30 the lugs 32, 34 of the pressure plates 37, 39.
- On the sides of the planing knives 24, 26 facing away from the grooves 28, 30 the two mutually identical cover shells 39, 41 are each supported by an end clamping surface (not described in more detail) and in this way press the planing knives 24, 26 secured against displacement against the pressure plates 37, 39.
- the pressure plates 35, 37 can be brought into alternating holding positions by turning them, in which they can alternatively use high-speed steel planing knives 24, 26 or carbide-reversing planing knives 23, 25 on their as Hold the supporting surface of the base or back surface in a form-fitting manner.
- the pressure plates 27, 29 are part of 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 in an equally adjustable manner if required or depending on the presence. 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:
- the carbide-reversible planer knives 23, 25 are adjusted by turning the adjusting screws 51, 53 so that the flight circle of the ones not shown Cutting 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 51, 53 are turned to the specified clamping torque.
- the high-speed steel planer knives 24, 26 are assembled and adjusted in the following way:
- the high-speed steel planer knives 24, 26 are adjusted by turning the adjusting screws 51, 53 so that the flight circle of the cutting edges of the planer knives 24, 26, not shown, 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 high-speed steel planer knives 24, 26 are moved into the desired position by being carried along by the pressure plates 35, 37 via the stops 48, 50.
- the clamping screws 51, 53 are turned to the prescribed tightening torque, the inclined position of the cover shells 39, 41 being compensated for by wedge-shaped washers, which are not designated here.
- 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.

Une coque de recouvrement (39, 41) maintient de chaque côté la plaque d'appui (35, 37) par une vis de serrage (43, 45) contre le corps de base (17). La plaque d'appui (35, 37) bloque la face de retenue (27, 29) située dans une rainure, au moyen des faces de maintien (31, 33) se trouvant sur une partie faisant saillie. Cette raboteuse à main permet de loger des lames de rabot différentes sur le porte-lames avec un seul moyen de fixation. La plaque d'appui (27, 29) est conçue de sorte à pouvoir maintenir, quelle que soit la position de rotation, les lames de rabot (23, 25) ayant des faces de retenue (24, 26) de structure et de position différentes, et notamment des lames rotatives minces en métal dur (23) de faible largeur ainsi que les lames rotatives épaisses en acier-rapide, de plus grande largeur.Hand planer provided with a rotary blade holder comprising a base body (17) which supports at least one support plate (35, 37) which supports a planer blade (23, 25), in particular a rotary blade hard metal (23, 25), with a profiled back and a smooth base surface, against said base body (17). A cover shell (39, 41) holds the support plate (35, 37) on each side by a clamping screw (43, 45) against the base body (17). The support plate (35, 37) blocks the retaining face (27, 29) located in a groove, by means of the retaining faces (31, 33) located on a projecting part. This hand planer can accommodate different planer blades on the blade holder with only one fixing means. The support plate (27, 29) is designed so as to be able to maintain, whatever the rotational position, the planer blades (23, 25) having retaining faces (24, 26) of structure and position different, and in particular thin rotary blades of hard metal (23) of small width as well as thick rotary blades of high-speed steel, of greater width.
