In some exemplary embodiments of the invention, the tensioning device is a vise, a jig in or for a lathe, a drilling machine, a milling machine, an NC or CNC machining center, a laser processing machine, a laser measuring station or other device.

In some exemplary embodiments of the invention, the angle adjustment device is configured to align auxiliary means used to align, set up, or adjust angular positions of a workpiece or component to be machined or measured. Aids may be, for example, adjustment means, adjustment aids, support parts, standard parts with predetermined dimensions or other components or individual parts which are suitable for aligning a workpiece.

A baseline may be referred to as a socket, base, reference surface, reference surface or the like in some exemplary embodiments of the invention. The base strip may have a scale or marking surface, which allows a determination or reading of a set angle by which the swivel strip or its workpiece bearing surface is to be unfolded or opened.

The scale may include, for example, linear or non-linear divisions, bar marks or the like.

The scale may have, for example, 1 degree intervals, 5 degrees intervals and / or 10 degrees intervals as subdivisions.

The scale or marking surface can be imprinted directly into the material of the base strip.

The embossing can be done for example by means of a laser inscription.

The scale or marking surface can be connected to the base strip by means of adhesive film or the like.

In some exemplary embodiments according to the invention, the base strip may have another display, such as a mechanical display, an electromechanical display, an electrical display or an electronic display, instead of or in addition to an optional scale.

An electrical or electronic display may be an analog display or a digital display.

The electrical or electronic display may, for example, indicate a sensor signal from an electromagnetic transmitter (eg from a coordinate converter, or "resolver") or from another angle measuring sensor or displacement sensor.

A displacement sensor may be based on different operating principles, such as a resistance change, a variable inductance, a variable capacitance, a variable luminous flux, a pulse count measurement, a transit time measurement, another method, or any combination of the aforementioned principles of operation.

In some example embodiments according to the invention, a swivel strip can be or have or be designated as a contact surface, contact surface, support, bearing surface, limb strip, an angle or the like.

The swivel strip can be provided and / or configured in some inventive exemplary embodiments for the direct or indirect application of a workpiece thereto.

For direct application, the pivot bar can be a contact surface, a line support (eg in the form of a roller or a pin) or a point support (eg a three-point support in the form of three ball or ball segments or other components, more than three balls or other components are also possible).

The aforementioned conditions (such as line support, point support) can be provided on a contact surface of the swivel bar. You can alternatively be distributed to a plurality of contact surfaces of a plurality of swivel bars of adjacently set up Winkeleinstellvorrichtungen. For example, two or more balls, ball segments or other components may be provided on a first abutment surface of a first angle adjustment device and one or more balls, ball segments or other components on a second abutment surface of a second angle adjustment device. A aligned on both the first and the second contact surface workpiece can thus rest on both contact surfaces together on prominent elements such as the balls, ball segments or other components.

A "spindle" is an example of an arbitrarily ausgestaltetes machine element that converts a rotational movement in a translational movement or converts, or vice versa. The term spindle is therefore not to be understood as limiting.

In some exemplary embodiments according to the invention, the conversion of a translational movement into a rotational movement is carried out by means of a movable, in particular directly manually displaceable, floating bearing block. The loose bearing block can, for example, at intervals in locking positions, which are arranged or stamped on or on the base bar, engage and thus accurately positioned.

In some exemplary embodiments of the invention, a spindle is or includes a threaded spindle, motion screw, ball screw, roller screw, or the like.

Spindles may include a threaded rod, in particular a cylindrical rod, on which a z. B. trapezoidal thread, a flat thread or other thread can be arranged.

A bearing block may in some exemplary embodiments of the invention be a spindle mount, a spindle bearing, a flange connected to the baseboard, a mount, a fixation section, or the like. The term fixed storage block is therefore not to be understood as limiting.

A floating bearing block may be or include a spindle nut in some exemplary embodiments of the invention. The floating bearing block may comprise an edge, a display, a marker or the like for reading a set angle of the swivel bar. The movable bearing block can be connected to the spindle and the base strip. For example, the loose bearing block can be moved axially by means of the spindle and simultaneously guided in a guide groove of the base strip. This may be advantageous because the spindle guide due to their structural design, for example, as a standard part with predetermined clearance fits, no exact or no sufficiently accurate guidance permits. This sufficiently precise guidance can then be achieved advantageously by means of the guide groove in the base strip.

In some exemplary embodiments according to the invention, the movable bearing block can have a locking screw, a clamping screw, a clamping lever, a clamping device or the like for fixing the floating bearing block to or on the base strip, in particular in a guide groove. The movable bearing block may have one or more sliding surfaces. For example, the movable bearing block may have one or more sliding surfaces for sliding and axial displacement on or on the base strip. Furthermore, the loose bearing block may have one or more sliding surfaces, along which slides the swivel bar. In particular, during the sliding of the swivel strip along a sliding surface of the movable bearing block, the swivel strip is simultaneously rotated about a swivel joint which is arranged in or on the base strip. The sliding surfaces of the movable bearing block on the one hand for sliding and axial displacement on or on the base bar and on the other hand for sliding the pivot bar are in particular different surfaces of the movable bearing block.

The bearing block or other portion may, in some exemplary embodiments of the invention, include a locking screw, a clamping screw, a clamping lever, a clamping device, a pin or the like for fixing the spindle in a rotational position. This device can serve to prevent accidental rotation of the spindle after adjusting an angular position of the swivel bar.

To this end, a pin may be provided to be inserted through an opening (eg, a through hole) of the fixed bearing block and into an opening (eg, may be a blind opening) of the spindle head or other portion of the spindle. If the opening of the spindle head is provided in the radial direction, a further rotation of the spindle can thereby be prevented.

Instead of an opening, in particular on the spindle, a plurality of openings may be provided.

In some exemplary embodiments according to the invention, the pivot bar is rotatably mounted in or on the base strip. The bearing may comprise a sliding bearing or a rolling bearing. In particular, the swivel bar is by means of a Bolzens stored, which can be referred to as a pin, pintle or the like. The bolt can be connected by means of a press fit with the swivel bar and by means of a clearance fit with the base bar. Likewise, a reverse arrangement is possible, ie a connection on the one hand between the bolt and the pivot bar by means of clearance fit and on the other hand between the bolt and the base bar by means of a press fit.

In some exemplary embodiments of the invention, the spindle is rotatably mounted in or on the fixed bearing block. For example, the spindle head can be arranged by means of a clearance fit in the fixed bearing block. This bearing assembly can be fixed by means of a cover plate or the like in the fixed bearing block. The cover plate is in particular detachable again, for example by means of a screw, connected to the fixed bearing block.

In some exemplary embodiments according to the invention, the swivel strip and the floating bearing block abut each other at least in sections. In particular, the pivot bar and the movable bearing block are punctiform or linear at two sliding surfaces to each other. The shape of the sliding surfaces can form the kinematics of the rotational movement of the pivot bar, which is generated by an axial displacement of the movable bearing block, in particular by means of the spindle.

In some exemplary embodiments of the invention, the sliding surfaces of the pivot bar and / or the floating bearing block are coated, hardened, polished, or otherwise machined.

In some exemplary embodiments according to the invention, the pivot bar is movably arranged on the pivot strip by means of a sliding movement or a displacement movement of the movable bearing block.

In some exemplary embodiments according to the invention, the surfaces of the swivel strip and the floating bearing block which are arranged to slide relative to one another are convex. In particular, at least one of the two surfaces has a convex surface shape. The surfaces may have a punctiform or a linear contact with each other. This can advantageously allow a simple, smooth and smooth movement of the pivot bar in an axial displacement of the movable bearing block. An undesirable static friction between the surfaces of the swivel bar and the movable bearing block can be advantageously prevented.

In some exemplary embodiments according to the invention, the increase in the angular position of the pivot bar by means of the translational displacement of the movable bearing block forms a non-linear function. A non-linear function in this context means that, for example, the floating bearing block is moved steadily and linearly, the angular increase or the angular decrease of the pivoting strip, however, increases or decreases non-linearly. By way of example only, the increase of the angle in a range between approximately 0 degrees and 33 degrees may correspond to a linear displacement of the movable bearing block of approximately 6.6 cm, the steps per degree corresponding to an approximately constant linear displacement of the floating bearing block of approximately 2 mm. In a subsequent range, the increase of the angle in a range between about 34 degrees and 60 degrees may correspond to a linear displacement of the floating bearing block of about 4 cm, wherein the steps per degree of approximately constant linear displacement of the floating bearing block by about 1.2 mm correspond. That is, the resolution or the ability to adjust an angle with an accuracy of less than one degree is easier to set in the range between 0 degrees and 33 degrees and read on a scale on the baseboard versus the range between 34 degrees and 60 degrees. This purely exemplary embodiment may have other resolutions in other embodiments. The exact relationships between the linear displacements of the movable bearing block and the rotation of the swivel bar by certain angles depends essentially on the geometry of the two sliding surfaces of the floating bearing block on the one hand and the pivot bar on the other.

In some exemplary embodiments according to the invention, the increase in the angular position of the swivel strip in the case of a translational displacement of the floating bearing block is progressive or linear in a first section and degressive in a second section. First and second sections can be replaced by at least a third section, the z. B. can be linear, separated from each other.

The third section or a middle section of the swivel strip and in particular its underside can run parallel to the upper side or workpiece contact surface of the swivel strip.

In some exemplary embodiments of the invention, the angular position of the swivel bar can be adjusted between zero degrees and sixty degrees by means of the translatory displacement of the floating bearing block.

In some exemplary embodiments of the invention, the Adjusting accuracy of the angular position of the swivel bar at least one degree. Additionally or alternatively, the scaling of a scale is at least partially accurate to one degree.

Since the angular position of the swivel bar correlates with the translatory displacement of the floating bearing block, in this embodiment, the pitch of the translational displacement is selected such that the adjustment accuracy of the translational displacement of the floating bearing block allows resolution of at least one degree of angular position of the swivel bar. A resolution of at least one degree may mean that the adjustment accuracy may be 0.5 degrees, 40 minutes, 20 minutes, or an intermediate value, or more precisely.

In some exemplary embodiments according to the invention, the displacement of the floating bearing block per degree of angular position of the pivoting strip is at least one millimeter.

In some exemplary embodiments according to the invention, at least one of the sliding surfaces of the swivel strip and / or the floating bearing block is at least partially polished and / or hardened. A hardening process of the material of the swivel bar and / or the floating bearing block may be, for example, or comprise a transformation hardening, a precipitation hardening or a work hardening. A hardened surface may include, for example, nitriding the material.

In some exemplary embodiments according to the invention, at least one of the surfaces of the pivoting strip and / or the movable bearing block which slide against one another is coated at least in sections.

In some embodiments, the pivot bar has two side walls with an internal cavity.

In some embodiments, the swivel bar has a cross-section in a U-shape.

In some embodiments, the angle adjustment device comprises a group of features that are non-detachably interconnected, at least without the use of tools, e.g. B. screwed or otherwise have features, or consists thereof. The advantages of such a design in which no components can be lost during use of the angle adjustment device are obvious.

Some or all of the exemplary embodiments according to the invention may have one or more of the advantages mentioned above or below. These may apply to the devices according to the invention as well as to the methods according to the invention.

The angle adjusting device according to the invention advantageously allows variable and stepless adjustment options for aligning workpieces in clamping devices.

Based on a possible small and compact size Winkeleinstellvorrichtung invention can be used in vices or as an adjustment on a machine table / on machine tables of processing machines.

Due to a long contact surface of the swivel strip for workpieces, even larger parts can be placed and aligned correctly.

The angle adjusting device according to the invention advantageously makes it possible with the aid of scales, which can be arranged on the base strip, to read any angle in accordance with sufficient accuracy. The Winkeleinstellgenauigkeit can optionally be realized up to the range of one second accuracy.

The angle adjusting device according to the invention can also be connected by means of the set according to the invention with, for example, two holes and connecting pins with one or more other Winkeleinstellvorrichtungen to advantageously also large parts comfortable and easy to hang up.

The present invention will be explained in the following with reference to the accompanying drawings, in which identical reference numerals designate identical or similar components, by way of example. In the partially simplified figures:

1 shows, purely by way of example, a first embodiment of an angle adjusting device according to the invention 100 in a front view. The view is called a front view, because in this view the set angles are readable on a scale.

The angle adjustment device 100 has a base bar 1 with a bottom or overlay 1a , a swivel bar 3 and a spindle 5 with a fixed storage block 7 and a floating bearing block 9 on. The swivel bar 3 is with the baseline 1 by means of a swivel joint 11 connected.

This swivel 11 allows a particular non-latching unfolding, unfolding or erecting the swivel bar 3 (short: unfold) when the floating block 9 to the left (referring to 1 ) is moved. The swivel joint 11 can be a plain bearing. The translational displacement of the movable bearing block 9 by a certain distance correlates with certain angles 15 or angular positions of the swivel bar 3 , relative to the bottom 1a that by means of a scale 13 can be read. In the in 1 shown position is the floating bearing block 9 positioned at about 43.5 degrees. That is, the displacement of the floating bearing block 9 between the scale positions 0 degrees (0 °) and 43.5 degrees ( 43 , 5 °) corresponds to an opening of the swivel bar 3 at 43.5 degrees. The angle 15 for measuring or aligning a workpiece resting on or on the swivel strip (in 1 not shown) thus corresponds to approximately 43.5 °.

In this case, angle indications are always based on the top side or the underside in case of doubt 1a the baseboard 1 ,

The correlation between the displacement of the floating bearing block 9 and unfolding the swivel bar 3 , ie the respective angles 15 or angular positions of the swivel bar 3 , depends on the two curves on the one hand at the bottom 17 the swivel bar 3 and on the other hand, the geometry 19 of loose bearing block 9 and especially its top off. In the 1 Curves shown result in a non-linear relationship between the translational displacement of the floating bearing block 9 and the angle of rise of the swivel bar 3 , In the range between 0 degrees and 20 degrees is the displacement of the floating bearing block 9 in this embodiment, per degree between about 2 mm and 2.2 mm. In the range between 20 degrees and 30 degrees varies the displacement and is in total per degree between about 2 mm and 3 mm. From 30 degrees, the displacement path per degree continuously decreases to about 1.1 mm scale distance between two marking lines. The larger the displacement per degree, the more accurate and finer the angle or the angular position of the swivel bar 3 be set. Consequently, in the present example, the 1 the swivel bar 3 between about 20 degrees and 30 degrees most accurately. Depending on the desired application of the angle adjusting device according to the invention 100 In other embodiments, this area can be chosen differently and the curves of the underside 17 the swivel bar 3 and the geometry 19 of loose bearing block 9 be adjusted accordingly.

In the purely exemplary embodiment of the 1 is the total length of the base bar 1 including the width of the fixed bearing block 7 about 150 mm. The radius of the bottom 17 the swivel bar 3 is in this exemplary embodiment in the upper area (relative to 1 ), which refers to the angle range between approx. 0 degrees and 20 degrees, approx. 80 mm (see right in 1 , corresponds here exemplarily the first section). Between about 20 degrees and 40 degrees is the course of the bottom 17 straight (center in 1 , corresponds here exemplarily the third section). Between about 40 degrees and 60 degrees is the radius of the bottom 17 approx. 33 mm (left in 1 , corresponds here exemplarily the second section).

There can be several radii.

The radius of that area, which is the free end of the swivel bar 3 is closer, here the first section, regardless of value specifications (that is, generally speaking) may be greater than that of that end, which the articulated connection or the hinge 11 assigned. An optional area located between these two areas, here the third area, may have a radius which is smaller than those radii of the first and second areas.

The floating bearing block 9 is at a translational displacement by means of a sliding movement along the bottom 17 the swivel bar 3 moved or guided. Due to this sliding movement, the swivel bar is directed 3 infinitely variable.

The floating bearing block 9 is by means of the spindle 5 moved in translation and moved. The spindle 5 is in the camp block 7 stored by means of a plain bearing. The spindle 5 is in particular manually rotated, for example by means of a hexagon socket wrench. The spindle head with the Hexagon socket profile is also exemplified as a functional unit in the fixed bearing block 7 arranged. This arrangement is in 3b visible.

The baseboard 1 indicates a page that is in 1 is visible, the scale with the degrees, in this exemplary embodiment from 0 degrees to 60 degrees. On the back, the in 2 is visible, is a guide groove 21 shown in the floating bearing block 9 to be led. Both the plain bearing of the spindle head in the fixed bearing block 7 as well as the leadership of the floating bearing block 9 in the guide groove 21 are optionally manufactured with the appropriate fits, so that preferably a precise and backlash-free operation is guaranteed. Both the plain bearing of the spindle head in the fixed bearing block 7 as well as the leadership of the floating bearing block 9 in the guide groove 21 can be provided with a suitable lubricant, for example with a bearing oil, a bearing grease or other lubricant.

The angle adjusting device according to the invention 100 can be made of one material or several different materials. In particular, the baseline 1 , the swivel bar 3 and the camp block 7 made of a metallic material, such as a stainless steel. By way of example, the stainless steel may be a chromium-nickel-molybdenum alloy, such as material number 1.2311 and short name 40CrMnNiMo8-6-4.

The swivel bar 3 also has at least one optional stop 2 on, for example, to be aligned workpieces 35 (please refer 6 ) on the workpiece contact surface 3a to prevent it from slipping or to prevent it from slipping.

The stop 2 can for example be designed as a metal pin.

The stop 2 can optionally by means of a press fit in a hole in the swivel bar 3 fixed or anchored.

1a in itself shows the first embodiment 1 but with an alternative arrangement of a stop 2a , The stop 2a is in this embodiment - unlike in the example of 1 - not on the swivel bar 3 or their workpiece contact surface 3a but on the camp block 7 or positioned or fixed elsewhere. The execution and fixation of the stop 2a can optionally be analogous to the stop 2 the 1 respectively.

2 shows the angle adjusting device according to the invention 100 out 1 in a perspective view from behind. This view can be called a back view.

The already to 1 described guide groove 21 for the floating bearing block 9 is clearly visible here. The floating bearing block 9 is in this leadership 21 displaced by a sliding movement. The floating bearing block 9 can by means of two screws 23 at a position or at a set angle of the swivel bar 3 be fixed. These are the screws 23 , or at least one of the two screws 23 , tightened so that the screw tip in the guide groove 21 clamps. This fixation can be used advantageously to determine a certain set angle for aligning a workpiece in a jig, in particular for the duration of setting and fixing the workpiece in the jig, immutable.

One in the floating bearing block 9 fixed, optional guide pin 25 can be an exact guidance of the movable bearing block 9 in the guide groove 21 guarantee. The guide pin 25 For example, by means of a press fit in the floating bearing block 9 be attached.

The swivel bar 3 Optionally, it has two sidewalls with an optional interior cavity which may be downwardly open as shown here. In addition or alternatively, it could be open at the top.

When folding the swivel bar 3 for folding the angle adjusting device 100 (please refer 3a and 3b) be the spindle 5 and the baseline 1 inserted in individual areas in this cavity or sunk in it. This creates a compact design of the angle adjustment according to the invention 100 for their transport and storage or storage.

3a shows the angle adjusting device according to the invention 100 in a slightly perspective view from the front and below. The angle adjustment device 100 is completely folded and can be easily transported and stored in this condition. The graduated scale (see 1 ) is optionally not visible in this folded state.

3b shows the angle adjusting device according to the invention 100 in a rear view or view from behind, again slightly perspective, but from below. For manual operation and turning of the spindle 5 the spindle head is here optionally designed for insertion of a hexagonal wrench.

In addition to the already to the 1 to 3 explained components is still an optional cover plate 27 for fixing or for protection against falling out of the spindle 5 from the camp block 7 when shown in the assembled state. Furthermore, an optionally provided bearing pin 29 shown to the the swivel bar 3 in the assembled state rotates or pivots.

5 shows a set according to the invention 200 with two angle adjusters 100 by means of two connecting pins 31 connected to each other. The connecting pins 31 are for example by means of press fits in the base bar 1 and in the camp block 7 fixed.

The set according to the invention 200 For example, can be used advantageously for large workpieces to large areas of the workpiece to the swivel bars 3 to create and thus align the workpiece tilt-proof to certain, adjustable angle. In the embodiment of the 5 are the settings of the spindles 5 not coupled together, so that both Winkeleinstellvorrichtungen 100 must be set separately to the or the respective desired angle values. Likewise, in this embodiment, the fixed bearing blocks 7 be fixed separately to fix a once set angle.

In other embodiments this is different; There are forced couplings and / or guides provided, the angle adjustment, the at one of the two Winkeleinstellvorrichtungen 100 done without the user's intervention on the other of the two angle adjustment 100 transfer.

Depending on the fixation of the connecting pins 31 in the baseboards 1 and in the fixed camp stands 7 can the two angle adjustment 100 again separated from each other, used individually and transported separately and stored.
