Work table ' · \

The invention relates to a work table according to the preamble of the protection claim 1. |

The invention is based on the object of a work table I

to create a workpiece with flat surfaces safely and I

can quickly clamp in various positions in space without |

that the work area around the workpiece is easy in some way

is restricted. t

This object is gekennzeich- by the protection in Claim 1 \ dissolved Neten characteristics. This ensures that the suction | plates are adjustable in at least two degrees of freedom, | whereby an optimal position for the machining is given for the workpiece. By holding the workpiece with negative pressure, on the one hand quick and easy clamping is possible, on the other hand its possibly sensitive surfaces remain

free from any damage.

Further developments of the invention are set out in the subclaims leads. I.

The features according to claim 2, which are accessible from all sides to the workpiece, are particularly advantageous here as well as unrestricted work space.

Due to the features according to claim 3 is formed by the full length uninterrupted in the table top Guide gap ensures adjustment and locking of the suction plates in every position.

The invention is explained in more detail below with reference to schematic drawings of an exemplary embodiment. It demonstrate:

Figure 1 is a front view of the work table according to the invention,

Figure 2 is a sectional view along II - II in Figure 1,

FIG. 3 shows a partial view according to FIG. 2, with the table top of the work table in a pivoted position is.

According to Figure 1, there is the work table according to the invention 25th

from a frame 1 on which a table top 2 with suction plates 8 is attached.

The table top 2 connects head ends 3 of stands 1a of the frame 1 and is pivotably mounted on this. The head ends 3 consist of plate-shaped elements, which are firmly connected to the stands by welding. By means of the clamping lever 5, the can be pivoted about an X-axis Table top fixed in any swivel position - "_ will be presented.

The table top 1 consists of two guide rails 6 and 6 arranged parallel to one another at a distance 7, which are connected to one another at their ends. These guide rails are usually square or right-angled cross-section, with their side surfaces 6a and 6b or 7a and 7b being ground and thus guideways represent.

One or more suction plates 8 are arranged on these guideways and along the X-axis, as shown by arrow B in FIG Figure 1 shows, displaceable and rotatable about its Y-axis.

The suction plate consists of a foot substructure 9, which is on

15th

a usually circular base plate 9a, whose lower surface for placing on the guideways 6a and 7a is also ground, is expediently attached by welding. On the foot substructure 9 is screwed 10 a suction head 11 is attached, which has a sensing valve (not

20th

shown) has a vacuum supply and thus suction only allowed when the workpiece is in place. By rubber lips 12 on the suction head 11 is a secure seal between this and the workpiece placed on it as well as a damage-free surface contact to the latter

25th

perform. The suction head 11 also has a connecting piece for connecting a vacuum hose coming from a pneumatic vacuum generator.

In the space between the guide rails, each

30th

Wells a clamping element 14 is used for each suction plate 8,

f that into the

Base plate 9a engages. The tensioning element becomes vertical through the side surfaces 6b and 7b of the guide rails

to the X-axis (in the horizontal plane), and is ent-35

along the X-axis together with the suction plate 8

bar, this being in any desired displacement position by a clamping lever 15 attached to the clamping element is detectable.

As Fig. 3 shows, the table top is pivotable about its longitudinal axis (X-axis) so that the attached to it Suction plates 8 have a total of three degrees of freedom: pivoting about the X axis, displacement along the X-axis, rotation around its vertical axis (Y-axis). There-

^ q through a determination of the workpiece in various, easily and quickly changeable positions in space achieved, which ensures that the workpiece from is freely accessible on all sides and the tensioning process does not restrict work.

The ends of the guide rails 6, 7 are preferably each welded to plates 4, which are connected to the head ends 3 are congruent and each of which is a spring-loaded Ball element 4a carries. In the head ends 3 are hemispherical at certain angular positions (e.g. 0 °, 45 °, 90 °) Recesses are provided into which the ball element engages, thereby adjusting the table top is made possible in these angular positions.
