Description

Technical Field

[0001] The present invention relates to a plate having at least one groove in its surface, wherein the groove is configured to receive a groove nut, a method for manufacturing a groove on the surface of a plate, and a groove nut configured to be received in a groove in the surface of the plate. Background Technology

[0002] It is known from the prior art that a plate has at least one groove in its surface, wherein the groove is configured to receive a slotted nut. The groove is designed to be T-shaped. Accordingly, slotted nuts designed to be T-shaped are known, which can be received in the groove. Clamping elements, etc., can be fastened to the slotted nut, typically in a threaded hole.

[0003] This type of plate is particularly used in slot platforms, where multiple slots are arranged parallel to each other, and the slots can extend in the transverse direction, longitudinal direction, or both. Furthermore, it is known that these slot platforms additionally have holes (arranged in a regular grid) in the surface of the slot platform and, where necessary, in the sidewalls, and are integral to a welding and clamping platform system. The welding and clamping platform system is based on a flexible, modular system consisting of system holes and compatible clamping elements. The clamping elements include stops, corners, bolts, clamps, prisms, supports, and other accessories.

[0004] A disadvantage of known plates with T-shaped grooves is that manufacturing the T-shaped grooves is complex and requires a large material thickness of the plate. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to provide a plate having at least one groove in its surface, a method for manufacturing the groove in the surface of the plate, and a groove nut, wherein the groove can be easily and inexpensively manufactured.

[0006] This technical problem is solved using the features of the independent claim. Advantageous embodiments of the invention are derived from the dependent claims.

[0007] In the plate according to the invention, which has at least one groove on its surface (wherein the groove is configured to receive a slotted nut), the cross-section of the groove perpendicular to its longitudinal direction is hexagonal. Compared to known T-grooves, the hexagonal groove can be manufactured more easily and cheaper, especially due to lower tooling costs. Here, the groove according to the invention can be applied to a lower material thickness, which reduces the weight of the plate. A larger diameter for the threaded hole of the slotted nut can still be achieved compared to known T-grooves.

[0008] In the groove according to the invention, having a hexagonal cross-section perpendicular to the longitudinal direction of the groove, the depth and width of the groove depend on the angle formed between the groove's adjacent surface and the plate's surface. It has proven advantageous that the angle between the groove's adjacent surface and the plate's surface is in the range of 42° to 48°, preferably 45°. At a 45° angle, one is in the optimal manufacturing zone for tools and machines in production technology.

[0009] The design of this invention features multiple slots arranged parallel to each other, extending in the transverse, longitudinal, or both directions of the plate. For example, such a plate can be combined with legs to serve as a slot platform. This results in a flexible clamping and guiding system for quickly and stably securing components in virtually every position and orientation, particularly for moving and positioning attachments and components or various movable system elements that can be guided, positioned, and clamped via one, two, or more slots.

[0010] To create the groove according to the invention in the surface of the plate, it is proposed to machine the plate from left and right at an angle ranging from 42° to 48° with respect to the surface of the plate, preferably 45°, using a disc milling cutter, and then broach the formed groove perpendicular to the surface of the plate using an end mill. Additionally, it may be provided to machine the edge of the groove on the surface of the plate using a radius milling cutter.

[0011] The slot nut proposed according to the invention, which is provided for receiving in a groove in the surface of a plate, has a hexagonal cross-section perpendicular to the longitudinal direction of the groove. This slot nut can be easily and inexpensively manufactured and advantageously works with the groove having a hexagonal cross-section perpendicular to the longitudinal direction of the groove in the plate. The slot nut can be introduced into the groove from one side of the plate.

[0012] Especially in plates with multiple slots arranged parallel to each other (where the slots extend in both the transverse and longitudinal directions of the plate), it is advantageous that the length of the slot nut is greater than the maximum width of the cross-section of the slot perpendicular to its longitudinal direction. This ensures that the slot nut can also bridge gaps at the intersections of the slots, and clamping is possible in these intersection areas.

[0013] To increase the applicability of the slotted nut according to the invention, it is proposed that the slotted nut be inserted into the slot from above and be rotatably constructed within the slot. The slotted nut can also be directly inserted into the slot via the table surface. Upon clamping, the slotted nut self-aligns, adjusts laterally within the slot, and locks in place. This is particularly suitable for long slots or when the occupancy of the plate does not allow for lateral insertion of the slotted nut.

[0014] These slotted nuts are designed to rotate 90° or 41.5° within the slot. To achieve this, material is removed symmetrically from the slotted nut according to the invention, which has a hexagonal cross-section perpendicular to the longitudinal direction of the slot, so that insertion into and rotation within the slot is possible.

[0015] The application possibilities of slotted nuts can be expanded by having the slotted nut have a threaded hole and being fitted with a cylindrical clamp adapter. This cylindrical clamp adapter can be connected to the slotted nut using a screw and is configured to accommodate a clamping tool with cylindrical feet. It is possible to use standard clamps from welding and clamping table systems using the clamp adapter. Attached Figure Description

[0033] Figure 31 A plate with a slotted nut, a clamp adapter, and a clamping tool is shown. Detailed Implementation

[0034] exist Figure 1 , Figure 2 , Figure 3 The diagram shows a plate 1 having a plurality of parallel grooves 3 arranged in its surface 2, wherein the grooves 3 extend in the transverse direction of the plate 1. The plate 1 is provided with sidewalls 4 and additionally with holes 5 arranged in a regular grid in the surface 2 and the sidewalls 4. It should be understood that the holes 5 and the sidewalls 4 are not mandatory requirements for this invention.

[0035] from Figure 3 The enlarged view of groove 3 clearly shows that the cross-section of groove 3 perpendicular to its longitudinal direction is hexagonal. The surface 6 of groove 3 adjacent to surface 2 of plate 1 forms a 45° angle with surface 2 of plate 1. According to the invention, an angle range of 42° to 48° has proven advantageous. The maximum width of groove 3 is designated as 6a, and the open width of groove 3 is designated as 6b.

[0036] Figure 4 and Figure 5 Other plates 1 are shown, which are related to Figures 1 to 3 The difference in the plate lies in the orientation of groove 3. In Figure 4In plate 1, groove 3 extends in the longitudinal direction of the plate. Figure 5 In plate 1, groove 3 extends in both the transverse and longitudinal directions, thus forming an intersection area 7.

[0037] according to Figure 6 and Figure 7 The method for manufacturing grooves 3 in the surface 2 of plate 1 is described in detail. First, plate 1 is machined from left and right at an angle 8a of 45° using a disc milling cutter 8. Here, according to the invention, an angle range of 42° to 48° has proven advantageous. It should be understood that the order is irrelevant here.

[0038] Subsequently, the edge 9 of the groove 3 on the surface 2 of the plate 1 is machined using a radius end mill 10. Then, the groove 3 is broached perpendicularly to the surface 2 of the plate 1 using an end mill 11. Here, the order of the last two steps can also be interchanged, that is, the groove 3 is broached first using the end mill 11, and the edge 9 is machined last using the radius end mill 10.

[0039] exist Figures 8 to 11 The image shows a slotted nut 12, which is provided for receiving in a slot 3 in the surface 2 of the plate 1. (See image from...) Figure 9 and Figure 11 As is particularly evident, the slotted nut 12 has a hexagonal cross-section perpendicular to the longitudinal direction of the slot 3. Here, the angle 13 is 45°, wherein, according to the invention, an angle range of 42° to 48° has proven advantageous. The slotted nut 12 has a threaded hole 14 into which clamping elements, etc., can be fastened.

[0040] exist Figures 12 to 15 Other slotted nuts 15 are shown, which are also provided for receiving in slots 3 in the surface 2 of the plate 1. From Figure 13 and Figure 15 As is particularly evident, the slotted nut 15 also has a hexagonal cross-section perpendicular to the longitudinal direction of the slot 3. Here, angle 13 is 45°, wherein, according to the invention, an angle range of 42° to 48° has proven advantageous. The slotted nut 15 has a threaded hole 14 in which clamping elements, etc., can be fastened. Figures 8 to 11 Unlike the slotted nut 12, the length of the slotted nut 15, represented by 16, is greater than the maximum width 6a of the cross-section of the slot 3 perpendicular to the longitudinal direction of the slot 3.

[0041] from Figure 16 As can be clearly seen from the diagram, the slotted nut 15, due to its length, can also bridge the gap in the intersection area 7 of the slot 3, and clamping is possible in these intersection areas 7.

[0042] exist Figures 17 to 21Another slotted nut 17 is shown, which (in Figure 18 and Figure 21 (As can be seen particularly clearly in the image) It has a hexagonal cross-section perpendicular to the longitudinal direction of the groove 3. Here, angle 13 is 45°, wherein, according to the invention, an angle range of 42° to 48° has proven to be advantageous. The groove nut 17 has a threaded hole 14 in which clamping elements, etc., can be fastened.

[0043] The slotted nut 17 is constructed such that it can be inserted into the slot 3 from above and rotated within the slot 3. For this purpose, the width 18 is smaller than the open width 6b of the slot 3. Furthermore, material is removed symmetrically at points on the surface 19, allowing the slotted nut 17 to rotate 90° within the slot 3.

[0044] exist Figures 22 to 25 The image shows an additional slotted nut 20, which is particularly evident in... Figure 23 and Figure 25 The groove nut 20 has a hexagonal cross-section perpendicular to the longitudinal direction of the groove 3. Here, angle 13 is 45°, and according to the invention, an angle range of 42° to 48° has proven advantageous. The groove nut 20 has a threaded hole 14 into which clamping elements, etc., can be fastened.

[0045] The slotted nut 20 is constructed such that it can be inserted into the slot 3 from above and rotated within the slot 3. For this purpose, the width 21 is less than the open width 6b of the slot 3. Furthermore, material is removed symmetrically at points on surface 22, allowing the slotted nut 17 to rotate within the slot 3 by an angle 22a, which in this embodiment is 41.5°.

[0046] according to Figure 26 and Figure 27 The detailed diagrams illustrate the insertion and rotation of slotted nuts 17 and 20. Figure 26 In the bottommost diagram, slotted nuts 17 and 20 are still outside slot 3. In the upper diagram, slotted nuts 17 and 20 are respectively placed into slot 3. Then, slotted nuts 17 and 20 are rotated clockwise in slot 3 until they reach their final position shown in the topmost diagram. Especially from Figure 27 The enlarged cross-sectional view shows the hexagonal cross-section of the slot nuts 17 and 20 in slot 3, which is perpendicular to the longitudinal direction of slot 3.

[0047] exist Figures 28 to 30 The image shows a clamp adapter 23, which has a cylindrical shape and is provided with a countersunk hole 24.

[0048] As from Figure 31As can be seen, the clamp adapter 23 can be connected to the slotted nut 12 using the countersunk screw 25. It should be understood that slotted nuts 15, 17, or 20 can also be used here. The clamp adapter 23 is configured to accommodate the clamping tool 26 with the columnar foot 27. It is possible to use standard clamps from accessories of the welding and clamping table system using the clamp adapter 23.
