Description

The present invention relates to a (stop) angle element, which allows a safer, more accurate and more flexible fastening and alignment of workpieces on a clamping or welding table, wherein the angle element is also mechanically more dimensionally stable.

It is known workpieces that are machined, such as those workpieces that are machined by welding to fix before machining on so-called clamping or welding tables, so that accurate and safe processing is possible. These welding tables have in particular a table top with a plurality of holes. Fixing bolts, so-called clamping bolts are introduced into the holes to clamp workpieces or other work accessories, such as stop angle, between the table top and the bolt.

Known stop angle have a plurality of through holes into which a clamping bolt can be inserted for fixing on the welding table.

The disadvantage is that the known stop angle can not be fixed flexibly and without effort on a welding table having a predetermined hole pattern in the table top, with any angle to the hole grid. Furthermore, the stop angles may be dimensionally unstable, e.g. The side walls can easily yield under heavy load or move relative to each other. This is not desirable in terms of the most accurate workpiece machining.

It is an object of the present invention to provide a (stop) angle element that can be fixed with less effort and less complicated on a table top, in particular at an arbitrary angle to a predetermined hole grid of the table top, and at the same time mechanically stable.

The object is solved by the invention according to the independent claim. Further preferred developments of the invention are described in the dependent claims.

The angle element according to the invention for a welding table can have at least two straight side walls, which can be arranged at a predetermined angle to each other. Further, the angle element may have a plurality of holes in at least one wall element. The wall element can be arranged on the side walls. The holes can be through holes. The holes can be round and / or long holes. Furthermore, the at least one wall element can have a substantially circular-arc-shaped groove, which can be designed as a through-hole.

The side walls furthermore preferably have at least one planar surface. The wall element is preferably arranged between the side walls. The wall element has in particular the function of lying flat on a table top of a clamping or welding table with a surface, so that the holes can be used to introduce fixing bolts, so-called clamping bolts, through the holes.

Through-hole should mean, in particular, that the element on which the bore is arranged is completely pierced, i. a through hole is present.

Furthermore, preferably, a center of the circular arc-shaped groove can lie on a contact point of two side walls. A contact point of the sidewalls is the point where two sidewalls abut or intersect.

The fixation of an inventive (stop) angle element on a table top of a clamping or welding table can be done for example by means of two clamping bolts. For this example, the wall element is just on the table top positioned so that at least two holes of the angle element are arranged exactly over two holes in the table top. The clamping bolts can then be inserted into the table bore through the hole in the angle element and fixed there. If the angle element is fixed with two clamping bolts in this way, a relative position of the angle element to the tabletop, among other things, can be set rotationally.

In particular, the invention offers the additional technical advantage that a clamping bolt can be inserted through the circular arcuate groove. Thus, the angle member is allowed along the circular arc groove, i. along a predefined path, can be twisted. This can be used to set a desired relative position between a hole grid of the table top and the angle element very accurately and without effort. The set relative position can then be fixed rotationally by simply inserting a second clamping bolt. On the other hand, first of all a first clamping bolt can be introduced into a round or oblong hole, so that the clamping bolt is used as a fulcrum. The (rotary) position can then be flexibly fixed by a second clamping bolt is inserted at the circular groove.

In addition to the above advantages, which in particular bring about a better and more flexible handling / use of the angle element, the circular arc-shaped groove or its arrangement according to the invention simultaneously offers the technical advantage that the mechanical (shape) stability of the angle element can be increased. The circular arc groove reduces possible bending of the side walls toward each other, especially when high mechanical loads act on the side walls.

The angle element may have three side walls, wherein at least two of the three side walls may be arranged in contact with each other. The side walls may each be arranged at a predetermined angle to each other. It can be two substantially circular arc Be provided grooves.

The three side walls may preferably be arranged along three edges of an imaginary rectangle. Particularly preferably, the three side walls are arranged at an imaginary rectangular shape along a longitudinal edge and the two shorter edges, substantially U-shaped. The three side walls can be flat and straight. The two grooves can preferably be arranged in each case in a section of the wall element which is arranged in a corner region between in each case two side walls.

In particular, two or more grooves further advantageously increase the mechanical dimensional stability of the angle element and allow the angle element can be flexibly and easily fixed on a table top in any relative position to a Tischbohrungsraster.

Further, at least one groove may be arranged such that a concave portion of the groove may point in a direction of a contact point between two side walls. The circular arc of the groove may preferably have an angle of less than or equal to 90 °. The angle can also be larger.

The arrangement of the groove, so that the concave part points in the direction of a corner between two side walls, supports in particular additionally the mechanical dimensional stability of the angle element.

The side walls may have a predetermined angle of 90 ° to each other. The at least one wall element can be arranged at an angle of 90 ° to the side walls. The arrangement of the wall element is preferably such that, when the side walls are arranged along the edges of an imaginary rectangle or rectangle, the wall element is arranged in the region of a base surface of the imaginary rectangle. The wall element can cover the entire imaginary base area or preferably a part of the imaginary base area. The arrangement of 90 ° between side wall and Wall element to mean that the wall element and the respective side wall are arranged substantially T- or L-shaped to each other.

The shaping of the angle element offers many possibilities and increased flexibility to arrange the angle element on a clamping table and / or other parts, e.g. Workpieces and / or tools to arrange relative thereto.

Furthermore, the angle element can have at least one stiffening element, which can be arranged substantially obliquely to at least one side wall. The stiffening element may have one or more sub-sections, each of which may be straight or may have a curvature. The stiffening element may have at least one longitudinal groove.

The stiffening element additionally increases the mechanical stability of the angle element, in particular for angle elements with long side edges. The longitudinal groove of the stiffening element also allows the stiffening element to bring in the least possible additional weight. The longitudinal groove preferably has a semicircular material recess.

Furthermore, at least one transverse strut element can be provided between the at least one wall element and the at least one stiffening element. The cross strut element may have at least one through hole. Furthermore, the outer contour of the cross strut element may be wavy.

The cross strut element allows in addition to the additional mechanical dimensional stability that additional holes can be provided, which provide additional fixation options. The wavy contour reduces the weight of the cross strut element.

Furthermore, the wall element can be in one piece and be arranged flush with a side edge of the side walls. In one piece, the wall element in particular, when the wall element is designed as a casting. If in each case one side edge of the side walls is arranged flush with a surface of the wall element, the wall element with this surface can be arranged flat on the table top.

Furthermore, at least one side wall may have a recess which may have a rounded edge. Further, in a portion around a bore, the wall member may have a recess which may have a rounded edge shape. The recess allows that even shorter clamping bolts can protrude as far as possible into the hole and the weight of the angle element can be reduced simultaneously. The rounded edge shape allows, in particular with clamping bolts with a round bolt head that the edge of the recess does not come into engagement with the bolt head. The recess in the side wall allows a reduction in the weight of the angle. The edge rounding of the recess makes it possible for the user to easily grasp the angle and to prevent a risk of injury on a sharp edge.

Furthermore, the side walls may have at least one bore. This allows the angle element to be used even more flexibly, for example by arranging and fixing angle element with a flat surface of a side wall on the table top.

Furthermore, the at least one edge of the at least one bore can be reworked, so that the reworked bore edge has a phase, a radius, a phase in combination with a radius, a phase in combination with a second phase, a radius in combination with a second radius or may have a phase in combination with a radius in combination with a second phase. In a through hole, the bore has two edges, at least one of which can be reworked. The post-processing improves in particular that a clamping bolt can be easily inserted into the bore. Phase in combination with radius means that along an axial direction of the bore initially a phase is provided, which merges into a radius - or vice versa. In particular, phase in combination with phase means that a phase having a first predetermined angle along a bore axis merges into a phase having a second predetermined angle. The same applies to a radius in combination with a second radius. With two phases and a radius, the radius can be arranged, for example, in the direction of the bore axis between the two phases.

Furthermore, the angle element may have at least two circular arc-shaped grooves, which may be arranged coaxially with each other. Furthermore, a round bore can be provided at a common center of the coaxially arranged circular arc-shaped grooves. Thereby the possibilities or the flexibility of handling the angle element, e.g. when mounting on a chuck table, further increased.

Further, at least one circular arc-shaped groove having a toothed inner edge. The toothing can be produced in particular and preferably in that a multiplicity of overlapping round holes is arranged in the wall element, which can be arranged along an imaginary circular arc. The toothing provides a grid that prevents a clamping bolt or a tool that is inserted into the circular arc-shaped groove to slip smoothly and unintentionally from a set position. The grid also provides additional assistance in accurately setting a desired angle of the angle member, i. adjusting an angle is simplified.

Further, the wall element may have a plurality of round holes, which may be arranged along an imaginary circular arc. Preferably, these round holes are not executed overlapping each other. Furthermore, at least two groups of round holes can be provided, each of which can be arranged along an imaginary circular arc, wherein at least one group on a convex side of the circular-arc groove and at least one Another group can be arranged on a concave side of the circular arc-shaped groove. This simplifies in particular the setting of a certain angle and creates additional possibilities for a flexible use of the more manageable angle element.

In summary, the invention thus provides a mechanically more dimensionally stable angle element, which is more flexible and can be fixed with less effort on a clamping or welding table.

Hereinafter, various examples of the present invention will be described in detail with reference to the drawings. Identical or similar elements in the figures are denoted by the same reference numerals. However, the present invention is not limited to the described embodiments, but further includes modifications of features of the described examples and combination of features of various examples within the scope of the independent claims.

FIG. 1 shows two perspective views of an angle element 1. The angle element 1 shown has three side walls 2a, 2b, 2c, which are arranged at an angle of 90 ° to each other, so that there is a substantially U-shaped arrangement. The side walls 2 a, 2 b, 2 c can be used, for example, for aligning workpieces with an angle with respect to one another on a clamping or welding table. The side walls 2a, 2b, 2c are shown in one piece with a wall element 3a, which, in particular Fig. 2a particularly shows, plan / even with an edge of the side walls 2a, 2b, 2c is arranged. The wall element 3a and the side walls 2a, 2b, 2c each have holes 4, which are shown running both as round holes 4a and 4b as long holes. The holes 4 are designed as through-holes, so that, for example, a clamping bolt (not shown) through the bore 4 in the receptacle of a clamping table (14, Fig. 15 ) can be introduced, so that for example the angle can be fixed by means of the clamping bolt on the table.

Furthermore, the show FIGS. 1a and 1b , as well as the FIGS. 2a and 2b in that the wall element 3a has two essentially circular-shaped or kidney-shaped grooves 5. These are arranged in a section of the wall element 3a, which is arranged in a corner region between in each case two side walls 2a, 2b, 2c. Longitudinal ends of the groove 5 each point in the direction of a side wall 2a, 2b, 2c. The groove 5 is oriented such that the concave portion is aligned in the direction of a corner between two side walls 2a, 2b, 2c. The grooves 5 increase according to the invention the dimensional stability of the angle element 1. Further, the grooves 5 can be used to receive a clamping bolt. By rotating the angle element 1 about an inserted in the groove 5 clamping bolt a very accurate and easy alignment of the angle element 1 can be achieved on a clamping table.

Next show the FIGS. 1a and 1b in that edges 7 and corners of the side walls 2a, 2b, 2c and edges 3b of the wall element 3a are rounded and partly undulating edges. This shape reduces the weight of the angle element 1, since the use of material is minimized. In particular with regard to a minimum weight, a recess 10 is arranged on the side walls 2a, 2b, 2c, which is arranged in particular in the direction of a side edge 7 of the side walls 2a, 2b, 2c. FIG. 1a shows that the side wall 2c has a recess 10 covering almost the entire edge length, which has rounded edges 10a. The edge 10a of the recess 10 has a waveform (see FIG Fig. 3d ), which simulates the outer shape of arranged in the side wall holes 4a. Further shows FIG. 1b in that two recesses 10 are provided on the side wall 2a, which are trapezoidal are formed.

The FIG. 2a further shows that a scale 11 may also be provided on a side edge 3b of the wall element 3a. In addition, the clarify FIGS. 3a to 3e the arrangement of the angle element 1 by means of side views and plan views. That's how it shows FIG. 3b in that the side wall 2 b can be made shorter than the side wall 2 a opposite it. Figure 3c can be seen that the axes of the holes 4a of the side wall 2b are arranged on a longitudinal axis of the elongated hole 4b of the side wall 2a.

The FIGS. 4 to 6 show a further aspect of the invention. The angle elements 1 shown have the kidney-shaped grooves 5 according to the invention, which are arranged in a corner section of the wall element 3 a of the angle element 1. Two parallel and spaced side walls 2a, 2b are each integrally connected to the wall element 3a and another side wall 2c at the edges. Furthermore, a stiffening element 8 is provided in one piece with the wall element 3a and extends between the two side walls 2a, 2b and, in the form shown, has two subsections 8a, 8b. The subsection 8a is made steeper to the side wall 2c than the subsection 8b. Both subsections are shown running straight. At a contact point of the two subsection 8a, 8b, a transverse strut element 9 is made in one piece and substantially at right angles. The combination of stiffening element 8 and transverse strut element 9 increases the stiffness of the angle of the element 1, in particular against the background of compared to the angle element 1 according to FIG. 1 increased distance between the side walls 2a and 2b. At the same time, the wall element 3a thus does not need to cover the entire rear side of the angle element 1, so that a minimum weight is made possible.

The edges 3b of the wall element 3a substantially and as shown represent the external shape of the bores 4a, 4b, so that a wave-shaped edge is formed. This leads to a maximum Weight reduction and good tangibility / handling of the angle element 1. Also, the cross member element 9 has a wave-shaped edge 9b. Holes 9a are arranged within a surface of the transverse strut element 9, so that they can be performed by this example, clamping bolts or tools.

The others Figures 5 and 6 further show in further views and representations that, for example, the subsections 8a, 8b may have at least one side a groove / recess 12 which is shown formed semicircular. Furthermore, at least the side wall 2c may have the divisions shown 13, which may be recorded or incorporated into the material. The subdivisions 13 can be used for example as a scale (see also FIG. 6e ). Furthermore, the show FIGS. 6a and 6d along with FIG. 4b Particularly well, another embodiment of the recesses 10, which are arranged in the side wall 2c. These flat away from the edge 7 of the side wall 2c and are separated from each other by projections 10b. In particular, the projections 10b have the purpose of forming small ribs for increasing the dimensional stability, while the depressions are designed as long as possible with a view to optimal weight reduction.

As the Figures 6b and 6c show particularly well, the shorter side wall 2b on three round holes 4a, which are in line with the three holes 4a, 4b of the longer side wall 2a.

Furthermore, the show Figures 7-9 and 10-12 Further embodiments of the angle element 1, which largely with the embodiment according to FIG. 4 to match. Differences in the FIGS. 7 and 10 in perspective shown angle elements 1 to the angle element 1 according to FIG. 4 in particular relate to the distance between the two side walls 2a, 2b and the length of the side wall element 2c and the number of transverse strut elements 9 and subsections of the stiffening element 8. Thus, the FIGS. 7 . 8th and 9a in that three subsections 8a, 8b 8c can be provided, of which two subsections 8a and 8b are just merging (see FIG. FIG. 9a ) and a less inclined portion 8c adjoins it. Between the sub-sections 8a, 8b, 8c two transverse strut elements 9 are arranged, each having holes 9a, as well FIG. 8b displays. The in the FIG. 8 well recognizable depressions / grooves 12 allow weight savings without affecting the stiffening function of the stiffening element 8. The length and arrangement of the side walls 2a and 2b is opposite to in FIG FIG. 4 embodiment shown not changed as the FIGS. 9b and 9c demonstrate. The side wall 2c has four depressions 10 arranged along its edge 7, as already described above. Between the recesses, the projections 10b are arranged ( FIG. 9d ).

The Figures 10a and 10b further show an even longer angle element 1 and an angle element 1 with an even longer side wall 2c and six recesses 10 described above Figures 11a and 11b show three transverse strut elements 9 are provided, each having a different length. Four subsections form the stiffening element 8, of which, as FIG. 12a shows, in each case two subsections with the same slope just merge into one another and a change in the pitch of the stiffening element 8 is provided substantially centrally of a longitudinal axis of the side wall element 2c. Like the other representations of the FIGS. 11a and 12b-e show, the side walls 2a, 2b, 2c, as well as those of the angle elements 1 described above, each arranged at an angle of 90 ° to each other and to the wall element 3a. The illustrated arcuate grooves 5 substantially cover an angle of 90 °, although other angle values may be useful.

Furthermore, all the holes 4a, 4b and the grooves 5 described above and shown in the figures can have a reworked bore edge 4c or 5c (shown by way of example in FIGS FIGS. 1a and 8a ). In the case of the existing through-holes, preferably only one of the two edges can be reworked or both. The post-processing of the edges improves in particular the handling when inserting clamping bolts. This Operation is less expensive if the edges 4c, 5c are reworked. The post-processing can be carried out in particular such that a phase or a radius in the region of the edge is incorporated into the material. Furthermore, an embodiment may also be provided, in which a phase transitions into a second phase, wherein both phases have different angles. Between the two phases, a transition can be provided by means of a radius. This embodiment with two different phases or two different radii allows a locking pin can be performed even better and thus smoothly inserted into the bore 4a, 4b, 5. Furthermore, the post-processing may also provide a combination of a radius and a phase. This refinement also improves the smooth introduction of a clamping bolt or another tool into the bores 4, 5.

The FIGS. 13a-c further show an angle element 1 with two side walls 2a, 2b and a wall element 3a, which has a circular arc-shaped outer edge 3b. The arrangement of the side walls 2a, 2b and the wall element 3a to one another is substantially equal to the angle elements 1 already described above. Differences to the angle elements 1 described above relate in particular to the arrangement of the circular arc-shaped grooves 5, which are arranged coaxially with each other on imaginary radii of different sizes , In a center of the grooves 5 a round bore 4a is arranged. There, for example, a clamping bolt can be introduced, which can act as a fixed axis of rotation when aligning the angle element 1. Aligning a desired angle is exemplary in FIG FIG. 15a by means of dashed edge lines of an angle element 1, which is rotated in different positions shown.

Furthermore, in particular show the FIGS. 13a, 13c in that one of the two grooves 5 has a toothed inner edge 5d, which enables an even more accurate alignment of the angle element 1. To further simplify the alignment is also an angle 13 on the back of the wall element 3a arranged. In addition, a linear scale 11 is provided on an edge 3b of the wall element 3a.

The FIGS. 14a, b further show an angle element 1, in particular the variant of the angle element 1 according to the FIGS. 13a-c is similar. This angle element 1 according to the Figures 14a-b has an arcuate groove 5 and two groups of round holes 4a, which are arranged along two imaginary circular arcs with different radii. A group is outside (on the convex side) of a circular arc of the circular groove 5, and a group is disposed inside (on the concave side) thereof. These round holes 4a, even in combination with the groove 5, can be used for a further simplified adjustment of the angle element, for example in relation to a bore grid of a clamping table 14. The arranged on the back of the wall element 3a angle 13 causes a further simplification of handling.

The FIG. 15a shows the example already explained above to the setting of a certain position of the angle element 1 with respect to a bore pattern of a clamping table 14th FIG. 15b further shows a clamping table 14, on the example, various angle elements 1 are fixed in different positions. FIG. 15b illustrates that the angle elements 1 can be attached to the clamping table 14 very flexible in any position and relative position to the bore grid of the clamping table 14. Furthermore, the shows FIG. 15b in that the angle elements 1 can also be fastened to one another, as shown, for example, in the region of the upper left corner of the clamping table 14.

In summary, it should be noted that the invention provides a mechanically dimensionally stable, lighter angle element, which is more flexible and can be fixed with less effort on a clamping or welding table, provides.
