Description

Dressing machine with a device for thickness planing dressing machines with equipment for thicknessing are especially built for woodworking.

In specialist circles, there are those with mechanical feed for the home Thickness planing work piece known under the name KoinbinierteAbrichthobel-und Thickness planer, while if only Ilairdvorachtil> available for thickness planing is, speaks of dressing machines with device for thicknessing.

The present invention relates to the latter type.

The numerous different constructions of the known combined Surface planer and t) ickenholnlmaschinen make it necessary that the Cl> er-ang from one type of processing to another, e.g. B. front dressing for planing, for the time being a change is made to the machine, e.g. 13.. \ Unfold or swivel away the dressing tables, putting on a chip hood, etc., while with the dressing machine with thicknessing device at the transition from dressing to thicknessing to this Purpose in addition to the machine special, to be attached to the planing tables of the same Parts or equipment used «must be earthed.

On the other hand, there is what is fundamentally new in the present invention in that there is a transition from one type of machining to another, e.g. B. from dressing for thicknessing, neither adding nor changing any additional parts or conversion of the machine itself is required. Only the height adjustment on the Required wood thickness is required.

In the drawing, the invention is shown schematically and by way of example. It shows Fig. R an embodiment of the planer with saw device for planing of the front (operator side), Fig. 2 is a plan view of the machine, Fig. 3, the view of the machine seen from the front side.

i is the task table that can be moved as easily as possible in the stand 2 a breaking machine, the height of which for the purpose of changing the chip thickness by kicking 16 is adjusted.

In the front part of the feed table, i.e. near the knife shaft, are attached from bottom to top resilient bolts 3, which by a device, z. B. raised or lowered by a shaft rotatable on the lever 3 with eccentric disks can be. When using the machine for dressing, the lever 3 is set so that that the pressure pins 3 remain under the surface of the table i while you use them to Thicknessing planes protrude more or less over the surface of the table i, according to your choice and so the wood to be processed the desired pressure on the guideway gives.

The pieces to be planed to thickness are now planed with the planed one Lying side up on the table i, it is pushed forward in the direction of the knife shaft. When the pressure pin 3 arrives, the wood is pushed up against the guide track by these pressed. This guideway is z. B. formed according to Figs. I to 3 of the drawing of the two irons 4 and 4a, which can be pivoted about the axis 5, and the irons on them in the width direction the machine movable, ruler-like guide iron 4b and 4e.

The undersides of the parts 4, 4a, 4b, 4 'lie in one plane, form so the guideway when thicknessing.

The parts 4b and 4c are z. B. guided in grooves of parts 4 and 4a and are held in the respective position by wing screws, etc.

To the guideway described above according to the strength to be able to adjust the workpieces during thicknessing parallel to the feed table i, are both the two pivot points 7 of the axis 5 as well as those opposite them both supports of the guideway at 8 directly or indirectly adjustable in height Elements, shown in the drawing, for example, as bolts sliding in housings, attached.

The parallelism of the guideway to the table surface is guaranteed, that the height adjustment parts, for example nine with each other are connected by rods, as shown, for example, schematically in Fig. i to 3 represented by the ones attached in points io, from a stand side to the other leading axes i i, which carry a lever 12 at each end, which over the small hinge axis 13 is connected to the bolts.

Both axes i i are connected to one another by rod 14, see above that by actuating the one lever 15, which is also seated on the axis i i the uniform height adjustment of the guideway parallel to the table surface i and 17 takes place. This also ensures the parallelism of the wood that has been planed to thickness secured. The respective set height of the guideway and thus the strength of the Thick planed wood can be read on the 18 scale.

Since the device for thicknessing is not in any, even when dressing Is a hindrance, it remains on the machine during this operation. Included the part 4 located directly above the knife shaft then only serves as protection against accidents. Replacement for the flap protection otherwise attached at this point.

The guideway, parts 4, 4 °, 46, 4 ', pivot upwards around the axis 5 in the pivot points 7 after loosening at 8 and there at the desired inclination to the table, 9o to 135 °, by tightening the nuts 6 determine.

Claims (3)

PATENT CLAIMS: i. Dressing machine with a device for thicknessing, characterized in that this device consists of a hinged guide track and spring-loaded pressure bolts arranged in the table of the dressing machine, which press the workpiece against the guide track in front of the planer knife. 2. Dressing machine according to claim i, characterized in that the guide track stored in two or four points as well as parallel in height by means of a rod is adjustable and lockable. 3. dressing machine according to claim i and 2, characterized characterized in that a camshaft pushes the pressure bolts in the table of the dressing machine adjusted in height bziv. the tension of the springs loading the pressure bolts changes.
