[0034] FIGS. 1, 2, 3 show a plate 1 which has a surface 2 with several slots 3 arranged parallel to one another, with the slots 3 extending in transverse direction of the plate 1. The plate 1 is provided with sidewalls 4 and additionally with bores 5, which are arranged in a regular grid in the surface 2 and in the sidewalls 4. It is to be understood that neither the bores 5 nor the sidewalls 4 are necessarily required for the present invention.
[0035] It is readily apparent form the enlarged illustration of a slot 3 in FIG. 3 that the cross-section of the slot 3 in perpendicular relation to the longitudinal direction of the slot 3 is a hexagon. The surfaces 6 of the slot 3 abutting on the surface 2 of the plate 1 enclose an angle of 45° with the surface 2 of the plate 1. According to the invention, an angular range of 42° to 48° has proven hereby to be advantageous. The maximum width of the slot 3 is designated by 6a and the open width of the slot 3 by 6b.
[0036] FIGS. 4 and 5 illustrate other plates 1, which differ from the plate of FIGS. 1 to 3 by the pattern of the slots 3. In the plate 1 of FIG. 4, the slots 3 run in longitudinal direction of the plate. In the plate 1 of FIG. 5, the slots 3 run both in transverse and in longitudinal directions of the plate 1, i.e. they form crossing zones 7.
[0037] The method for the production of the slots 3 in the surface 2 of the plate 1 is explained in greater detail with reference to FIGS. 6 and 7. Initially, the plate 1 is machined with a disc milling cutter 8 from the left and from the right at an angle 8a of 45°. According to the invention, an angular range of 42° to 48° has proven to be advantageous. It is to be understood that the sequence plays no role here.
[0038] Subsequently, the edges 9 of the slot 3 on the surface 2 of the plate 1 are machined with a radius cutter 10. The resultant slot 3 is then broached with a face milling cutter 11 at a right angle to the surface 2 of the plate 1. The sequence of the last two method steps may also be reversed, i.e. the slot 3 is initially broached with the face milling cutter 11 and only at the conclusion are the edges 9 machined with the radius milling cutter 10.
[0039] FIGS. 8 to 11 show a sliding block 12 which is intended for acceptance in the slot 3 in the surface 2 of the plate 1. As is particularly apparent from FIGS. 9 and 11, the sliding block 12 has a cross-section in perpendicular relation to the longitudinal direction of the slot 3, which cross-section is a hexagon. The angle 13 is hereby 45°, with an angle range of 42° to 48° proven to be advantageous according to the invention. The sliding block 12 has a threaded bore 14 in which clamping elements or the like can be attached.
[0040] FIGS. 12 to 15 show another sliding block 15 which is also intended for acceptance in the slot 3 in the surface 2 of the plate 1. FIGS. 13 and 15 particularly clearly show that this sliding block 15 also has a cross-section in perpendicular relation to the longitudinal direction of the slot 3, which cross-section is a hexagon. The angle 13 is hereby 45°, with an angle range of 42° to 48° proven to be advantageous according to the invention. The sliding block 15 has a threaded bore 14 in which clamping elements or the like can be attached. In contrast to the sliding block 12 of FIG. 8 to 11, the length of the sliding block 15, designated by 16, is greater than the maximum width 6a of the cross-section of the slot 3 in perpendicular relation to the longitudinal direction of the slot 3.
[0041] The illustration of FIG. 16 clearly shows that the sliding block 15 can also bridge the gaps at the crossing zones 7 of the slots 3 as a result of its length, and a clamping in these crossing zones 7 is possible.
[0042] FIGS. 17 to 21 show another sliding block 17 which, as is readily apparent from FIGS. 18 and 21, has a cross-section in perpendicular relation to the longitudinal direction of the slot 3, which cross-section is a hexagon. The angle 13 is hereby 45°, with an angle range of 42° to 48° proven to be advantageous according to the invention. The sliding block 17 has a threaded bore 14 in which clamping elements or the like can be attached.
[0043] The sliding block 17 is designed in such a way that it can be threaded into the slot 3 from above and can be rotated in the slot 3. For this purpose, the width 18 is smaller than the open width 6b of the slot 3. Furthermore, material on the surfaces 19 has been point-symmetrically removed so that the sliding block 17 is rotatable by 90° in the slot 3.
[0044] FIGS. 22 to 25 show a further sliding block 20 which, as is particularly apparent from FIGS. 23 and 25, has a cross-section in perpendicular relation to the longitudinal direction of the slot 3, which cross-section is a hexagon. The angle 13 is hereby 45°, with an angle range of 42° to 48° proven to be advantageous according to the invention. The sliding block 20 has a threaded bore 14 in which clamping elements or the like can be attached.
[0045] The sliding block 20 is designed in such a way that it can be threaded into the slot 3 from above and is rotatable in the slot 3. For this purpose, the width 21 is smaller than the open width 6b of the slot 3. Furthermore, material has been removed point-symmetrically on the surfaces 22, so that the sliding block 17 in the slot 3 is rotatable by an angle 22a, which is 41.5° in the exemplary embodiment.
[0046] Threading and rotating of the sliding blocks 17, 20 are explained in greater detail with reference to the detailed illustrations of FIGS. 26 and 27. In the lowermost illustration of FIG. 26, the sliding blocks 17, 20 are still outside of the slot 3. In the illustration above, the sliding blocks 17, 20 are each placed into the slot 3. The sliding blocks 17, 20 are then rotated clockwise in the slot 3 until reaching the end position of the sliding blocks 17, 20 shown in the uppermost illustration. In particular the enlarged sectional view of FIG. 27 shows the hexagonal cross-section of the sliding blocks 17, 20 in perpendicular relation to the longitudinal direction of the slot 3 in the slot 3.
[0047] FIGS. 28 to 30 illustrate a clamp adapter 23 which has a cylindrical shape and is provided with a countersunk bore 24.
[0048] As is apparent from FIG. 31, the clamp adapter 23 can be connected to the sliding block 12 with a countersunk screw 25. It is to be understood that the sliding blocks 15, 17 or 20 may also find application here. The clamp adapter 23 is provided for receiving a clamping tool 26 with a cylindrical foot joint 27. The clamp adapter 23 enables the use of standard clamps from the accessories of a welding and clamping table system.
