Definitions
- the invention relates to a clamping device for workpieces specially prepared for clamping in this clamping device, and a clamping method for workpieces.
- the workpieces For machining in machine tools, the workpieces must be clamped and held firmly in suitable clamping positions.
- the clamping must be such that, in particular in the case of machining operations to be carried out on the workpiece, larger forces can also be dissipated without difficulty and do not lead to the workpiece being displaced.
- the workpiece should be as easily accessible as possible in order to be able to perform as many machining operations on the workpiece as possible with a single clamping.
- the two requirements are somewhat opposed to each other. If the workpiece is to be accessible, for example, from five sides, a clamping is required which does not block access to the sides to be machined.
- Clamped machine vice the machine vice with its two clamping jaws covers two opposite sides of the workpiece over a large area. This affects access to the workpiece.
- the clamping device has two jaws or
- Clamping elements that are provided with form-locking elements that are complementary to corresponding coupling elements of the workpiece.
- the coupling elements are specially formed on the workpiece in a preparatory work step. They generally have no other function, but only serve to clamp the workpiece in question in the clamping device according to the invention. Due to the form-locking element, this enables the workpiece to be attacked, for example in an extremely narrow strip-shaped area. The non-positively clamped workpiece between the clamping elements is also held positively by the form-locking elements and the coupling element. It is
- both clamping elements are each provided with corresponding positive locking elements, this also prevents any turning, swiveling or tilting movement of the workpiece.
- the corresponding holding forces are transferred from the positive locking elements to the clamping elements and derived. This applies regardless of whether the two clamping elements are adjustable towards and away from each other or only one of the two clamping elements is movably arranged. If the clamping elements are pressed against the workpiece so that they clamp it between each other, the positive locking elements automatically engage in the coupling elements and lock the workpiece.
- the mixed positive and non-positive clamping or holding of the workpiece in the clamping device has the additional advantage that the workpiece assumes a defined position in relation to the clamping device from the start. Incorrect positioning can be almost completely ruled out. This can significantly reduce the amount of work involved in setting up the workpieces.
- the form-locking element which can be formed, for example, by projections or depressions on the tensioning elements, are preferably connected in one piece to the tensioning elements.
- the coupling elements of the workpiece are depressions or projections which are attached to the workpiece in a machining step preceding the clamping process.
- the work step can be an embossing machining process in which the clamping area of the workpiece is plastically deformed slightly. This is preferably done in an area of the workpiece that is not impaired in function by the application of depressions or projections.
- the coupling elements can also be eliminated after the machining has ended. This is possible, for example, in a grinding or milling process that then takes place in a different, possibly conventional clamping.
- the form-fitting and coupling elements can be designed, for example, in the manner of a toothing.
- the individual teeth and associated depressions are each arranged equidistantly.
- the truncated pyramid shape has proven to be advantageous for the form-fitting elements or the coupling elements.
- the shape of a truncated cone is also possible. In both cases it is achieved that the form-fitting elements find their way into the associated coupling elements relatively easily. This is particularly the case if the flank angle of the positive locking elements is not too large. E.g. it has proven to be advantageous if the angle of the side faces of the pyramid-shaped projections with respect to the contact surface is not greater than 45 °.
- the interlocking elements are arranged, for example, in a single straight row on one edge of the clamping jaw. This enables particularly tight, space-saving clamping of workpieces. However, other arrangement schemes are also conceivable and possible. If very large forces are to be absorbed, two or more row arrangement patterns can be used, for example.
- the interlocking elements and the coupling elements are of equal size, or if they even have a slight play to one another, a real functional separation between the contact surface and the interlocking element is carried out in such a way that the contact surfaces serve for positive locking, while the interlocking elements secure the position and position of the workpieces processing.
- the advantage of this embodiment is that the locking and coupling elements are not subjected to any stress during tensioning and a stress only occurs during processing. However, if a clamping is desired in which micro-movements of the workpiece are also well suppressed, it can be expedient if the elements designed as projections are at least slightly larger than the associated elements designed as recesses.
- the oversize or undersize of the interlocking elements provided on the clamping elements and the choice of material for the clamping elements are preferably set such that plastic deformations, if they occur at all, remain restricted to the workpiece. With such clamping elements, a precise and secure clamping of workpieces is possible in the long term.

- Fig. 3 shows a clamping element for the clamping system according to the
- FIGS. 1 to 3 shows a clamping element belonging to the clamping system according to FIGS. 1 to 3 with modified form-locking elements, in a schematic plan view
- FIG. 5 shows a modified embodiment of a clamping system with a plurality of clamping elements provided with positive locking elements, in a schematic plan view, and
- Fig. 6 shows a further embodiment of a clamping system with clamping elements, which are provided with connecting elements, in a schematic plan view. Description :
- a workpiece 1 is illustrated in FIG. 1, which can be firmly clamped by means of two clamping jaws 2, 3 in a machine tool which is not further illustrated.
- the clamping jaws 2, 3 are held in the direction of the arrow 4 illustrated in FIG. 1 and are adjustable towards and away from one another on an adjusting device (not illustrated further).
- the adjusting device is set up to apply a force to the clamping jaws 2, 3, if necessary, which moves the clamping jaws 2, 3 towards one another.
- clamping jaws 2, 3 illustrated in FIG. 1 are mirror-symmetrical to one another. The following description of the clamping jaw 2 accordingly applies accordingly to the clamping jaw 3.
- the clamping jaw 2 has, for example, a cuboid base 5, which has a flat surface 6 on its side facing the tool 1.
- the flat surface 6 serves as a contact surface for a clamping surface 7 which is provided on the workpiece 1 and is also of flat design and which is hidden in FIG. 1 due to the perspective.
- the workpiece 1 On the opposite side, the workpiece 1 has a corresponding flat surface 8 facing the clamping jaw 3, which is mirror-symmetrical to the flat surface 7 and is visible as a result of the perspective in FIG. 1. It will be described below instead of the clamping surface 7.
- the clamping jaws 2 and 3 serve to grasp the workpiece 1 only in the immediate vicinity of its lower edge 9. If necessary, however, can also attack in other places.
- a plurality of projections 11 arranged in a row are formed on the contact surface 6 and serve as form-locking elements.
- the projections 11 are identical to one another and extend along an upper edge 12 of the clamping jaw 2.
- FIG. 2 a section of the clamping jaw 2 is illustrated on a different scale.
- the projections 11 are formed in the shape of a truncated pyramid. They are in each case an integral part of the base body 5. As can be seen from FIGS.
- the truncated pyramid-shaped projections 11 are elongated in the direction of the edge 12 , ie they have a rectangular base. In principle, the shape can differ, but the truncated pyramid shape with a rectangular base shows good power transmission with a minimum of space.
- the slope angle, ie the angle that each side surface 14, 15, 16, 17 each includes with the contact surface 6, is preferably relatively flat.
- the slope angles of the side surfaces 14, 15 adjoining the narrower edges of the base area are preferably less than 45 °.
- the height of each pyramid-like provision 11 is preferably not greater than the length of the narrower edge of the base.
- Recesses 18 are formed in the workpiece 1, each of which is assigned to the projections 11 and shaped accordingly.
- the recesses 18 are produced, for example, in an embossing process and are designed to be complementary to the projections 11 serving as form-locking elements.
- the recesses 18 are each truncated pyramid-shaped depressions.
- the procedure for clamping workpieces 1 is as follows:
- the workpiece 1 Before clamping, the workpiece 1 is first prepared for clamping on its clamping surfaces 8. To it is placed in an embossing device and, if the recesses 18 are desired at precisely predetermined locations, first adjusted. This is particularly necessary if the workpiece 1 is to be machined without further adjustment after clamping in the clamping jaws 2, 3. In other cases, in which the clamped workpiece 1 is first touched or otherwise measured in order to determine its actual position, an adjustment in the embossing device can also be omitted.
- the row of successive recesses 18 shown in FIG. 1 is embossed in the embossing device by means of an embossing stamp.
- This can be done both with a linearly movable flat stamp, which presses in all the recesses 18 at the same time, and with a stamp, which only produces a single recess 18.
- this stamp is moved one position at a time, so that all recesses 18 are produced one after the other.
- the workpiece is guided between the clamping jaws 2, 3, after which they are moved towards each other in the direction of the arrow 4 until the projections 11 engage in the recesses 18 and press the contact surfaces 6 firmly against the clamping surfaces 7, 8 .
- the projections 11 sit without play in the recesses 18 and hold the workpiece 1 in a form-fitting manner if the forces to be absorbed are greater than the static friction between the contact surfaces 6 and the clamping surfaces 7, 8. Every play and every positioning uncertainty becomes due to the frictional support of the form-fitting connection avoided. Vibrations of the workpiece 1 during machining can thereby be avoided.
- the projections 11 described above, which serve as positive locking elements, are of straight-sided design. As illustrated in FIG. 4, however, it is also possible for the flanks 14, 15, 16, 17 of each frustoconical projection 11 to be curved. This is particularly true with regard to the recesses 18, which are advantageously formed on the workpiece in the embossing process and which are consequently not delimited by sharp edges. With a suitable flank curvature it can be achieved that each projection 11 rests almost completely over the associated projection 18. This serves to ensure the power transmission and thus maximize the transferable forces.
- the curvature and curvature of the projections 11 are adapted to the surface courses which are formed on the workpiece during the embossing.
- the projections 11 with a more or less large oversize, so that they sit prestressed in the recesses 18 during tensioning.
- the flat slope angles of the projections 11 prevent the workpiece 1 from wedging with the clamping jaws 2, 3.
- clamping system described above got by with two jaws 2, 3. As illustrated in FIG. 5, however, several, for example four, clamping jaws 2, 3, 2 ', 3' can also be provided, which are arranged opposite one another in pairs.
- the clamping jaws 2, 3, 2 ', 3' are designed in accordance with the clamping jaws described above and each have projections 11 which engage in correspondingly prepared recesses in the workpiece 1.
- At least two of the clamping jaws 2, 3, 2 ', 3' are displaceably arranged by means of a power-operated adjusting device, as indicated by the arrows 4, 4 '.
- clamping jaws 2, 3 each have flat contact surfaces 6, they can, as the embodiment according to FIG. 6 shows, also be curved, for example cylindrical.
- the illustrated clamping jaws 2, 3, 2 ' serve to clamp a cylindrical workpiece 1, each clamping jaw 2, 2', 3 having a cylindrically curved contact surface 6, the curvature of which is determined by the radius of curvature of the cylindrical workpiece 1.
- Each clamping jaw is in turn provided with projections 11, which are arranged along an edge 12 of each clamping jaw 2, 2 ', 3.
- the protrusions 4 can also be arranged in the axial direction, in contrast to the embodiment shown, the clamping jaws then only having clamping edges, the narrow strip-shaped contact surfaces of which are occupied by protrusions 11 .
- Clamping jaws 2, 3 are also formed by recesses.
- the workpiece 1 must be provided with corresponding complementary projections in the preparatory work step.
- the advantage of this embodiment and procedure lies in the fact that the projections on the workpiece 1 required for clamping can be easily removed after machining.
- a clamping system has been provided for clamping in front of workpieces 1, to which two or more clamping jaws 2, 3 belong.
- the clamping jaws are fitted with regularly arranged positive locking elements, for example projections 11, which protrude from corresponding contact surfaces 6.
- Complementary recesses 18, which serve as coupling elements, are formed on the workpiece in a preparation step. This can be done by embossing.
- the clamping system provides a mixed friction and positive clamping of the workpiece 1, which enables the transfer of large holding forces with a small area requirement on the workpiece and on the clamping elements 2, 3.
