Description

GERMAN

The invention relates to a suction clamping device for workpieces, in particular wooden panels, with a suction plate having a ring seal.

It is known to clamp plate, cylinder or spherical workpieces of various types by means of suction. A suction plate with a suction device is used to clamp these workpieces connected is. The workpiece is placed on this suction plate; there is between workpiece and Suction plate arranged a rubber seal, which thanks to its elastic property a flawless Sealing between workpiece and suction plate guaranteed.

The aim of the invention is to provide a simply designed, easy-to-use suction clamping device, in particular for wooden panels, to create. According to the invention, the suction plate is on one at the same time attached as a suction pipe serving pipe stand, on the upper part to control the suction air with Handles provided rotary valve is mounted, while the lower end of the tube stand with a connected housing-like, designed as a pedestal base and stored in this the air delivery unit is.

The arrangement of the rotary slide valve which is rotatable about the stator axis and which is provided in the subject matter of the invention on the upper part of the stand enables convenient operation of the suction clamping device. The one with Swivel lever-like handles provided rotary valve, which is a short distance below the suction plate sits, is easily accessible, from all sides, regardless of the respective stand the operator.

Due to the housing-like base design and storage of the air delivery unit in the base the stability of the suction clamping device thanks to the deep arrangement of the unit in the center of the axis of the Stand significantly increased.

In the drawing, an embodiment of the suction clamping device is shown. It shows

1 shows the device with a workpiece in a vertical central section,

FIG. 2 is a plan view corresponding to FIG. 1,

3 and 4, on a larger scale, the rotary valve in the closed and open position,

FIG. 5 shows a cross section along the line AB in FIG. 4.

In the housing-like base 1 of a stand, which consists of a tube 2, an electric motor 3 is mounted, the shaft 4 of which carries an air feed wheel 5 at the bottom. In an intermediate plate of the housing 1 and in one The plate 6, which closes off the base housing at the bottom, has holes 7, 8 for the passage of air.

has been named as the inventor

The pipe stand 2 continues upward into an upper part 2 'with a smaller diameter, in which a closed transverse wall 9 is located. A support table 10 is placed on the upper part 2 ', which is fixed or adjustable in height can be arranged on the upper part 2 '. To fix the support table 10, both

«5, for example, a known clamping lever 11 can be used.

On the support table 10 is a self-contained, made of elastic material at the top Ring seal 12 is arranged, which could also be let into a groove in the table 10.

When the air delivery unit 3 to 5 is running, the stand tube 2, 2 'serves as a suction line through which air is sucked in from above, which emerges from the holes 8 below. A workpiece 13, for example a wooden one Plate, is placed on the seal 12, whereby between the underside of the workpiece 13, the seal 12 and the support table a cavity

14 is formed, which is connected to the suction line 2, 2 '. By the generated in cavity 14 Vacuum is the workpiece 13 on the table 10 securely held so that the edges of the Workpiece edge, for example, connected veneer

15 can be cut or sawed off on all sides.

The suction line can be provided with an inserted sieve 16 at the top to prevent sawdust from entering or the like to avoid.

In order to be able to loosen the held workpiece 13 quickly, without stopping the air delivery unit Having to wait after switching off the engine, a valve is provided in the suction line to make the connection to be able to produce quickly with the outside air. The valve consists of an on. the upper part 2 'rotatable arranged slide 17, which is provided with one or more handles 18. The swivel

About 17 is branched out with longitudinal channels 19 on the inside; the 2 $ Urid '21 holes provided in the upper part 2' work together. As Fig. 3 shows, the holes are * 20 * above the ^ minVKaHd> 9 ;. while the "· holes" are below the door, it is arranged! ·. 5> Between the longitudinal channels 19, the rotary valve 1Ψ is provided with radial bores 22. 3 shows the rotary slide valve in the working position, in which the air can step down on the arrow path drawn from above through the soldering bar 20, the longitudinal channels 19 and the holes 21. Fig. 4 shows the rotary valve IV in the open position, the interior of the upper part 2 'through the holes 20 and the bores 22 is in connection with the Außeniüft. With the air delivery unit running all the time, it is only necessary to turn the rotary valve a few degrees in order to cancel the suction effect in the cavity 14 as shown in FIG. 4 and to restore it when it is turned back. The rotary valve !? expediently rests on the collar 23 caused by the expanded stator tube 2. An on / off switch 24 for the motor 3 can be assigned to the tube or stator. In the illustrated embodiment, the stand is mobile. For this purpose, the base housing 'is provided with two running rollers 25, which can be arranged parallel to one another, as shown in FIG. A support26, which is made of a material with a higher coefficient of friction, serves as the third support point. This support26 can be inserted into a corresponding cavity of the ·; Be used socket housing. The stand constructed in this way has the advantage that it can be easily moved in a slightly raised position with the aid of the two castors and that it is sufficiently held on the floor when the support 26 touches the floor. t claims: 1. Suction clamping device for workpieces, in particular wooden panels, with a suction clamping plate having a ring seal, characterized in that the suction clamping plate (10) is attached to a pipe stand (2, 2 ') which also serves as a suction line, on its upper part (2') for Control of the suction air is mounted on a rotary slide valve (17) provided with handles (18) and the base of which is designed as a housing-like base (1) that accommodates the air delivery unit (3, 4, S). 2. suction clamping device according to claim 1, characterized in that the upper part (2 ') of the pipe stand, s separated from the lower part (2) by a transverse wall (9) arranged in the region of the rotary valve (17) and by transverse bores (20, 21, 22 ) in the upper part, lower part and rotary valve as well as through longitudinal channels (19) in the rotary valve can either be connected to the outside air or to the lower part.
