Definitions
- the invention relates to holders for tools for separating and / or machining. It can be used in classical mechanical engineering on machine tools, but also in other fields where, for example, a division or division of semi-finished or semi-finished products is to be performed.
- brackets are used for the brackets, which are as rigid and stiff as possible and hold the tools accordingly.
- Active can at least not be influenced sufficiently promptly during processing. It is therefore an object of the invention to propose solutions with which a cutting and / or cutting machining can be better influenced directly in the machining process.
- At least one element is arranged or accommodated in a holder, with which changing paths, acting forces or moments can be detected and exerted on a tool.
- the time derivatives of changing paths and / or forces, by establishing a temporal reference can be determined and taken into account.
- the same element (s) are reacted, so that, for example, a compensation can be achieved.
- This can, for example, influence the positioning of tools or reduce the noise emission.
- the latter aspect can e.g. by influencing the excitation frequency for vibrations.
- elements for the detection and other elements for the influence can also be present on a holder.
- the elements to be used according to the invention can be combined with a multifunctional material be formed. You can be made entirely of such a material but only in parts with such a material.
- An electrical contact should be provided if, for example, detected measured variables are to be transmitted to a machine control in order then to be able to regulate the machining process taking their consideration into consideration. However, such a contact can also be used to actively influence the clamping or holding the respective tool can.
- Multifunctional materials can be piezoelectric, ferroelectric, magnetostrictive fluids or even shape memory materials, with which elements alone or in combination can also be used with other materials.
- the first two types of materials are suitable for detection, as a sensitive function, and also for the active part.
- the arrangement of elements can be chosen so that, for example, the holder for the tool forms an abutment.
- At least one such element should be in direct contact with the tool.
- shape memory material on one or more element (s) which changes its shape depending on the temperature sudden, this can be used to actively respond to exceeding a predetermined maximum temperature tool and / or holder to respond.
- a state can also be detected by e.g. a contact is closed with an electrically conductive shape memory material during the change in shape and this can be transmitted as a corresponding signal to the machine control.
- connection to an electronic controller preferably that of the respective machine, should be present in each case as far as possible.
- Elements, but also modules formed with several elements for example, be designed as a hollow cylinder, which can then be pushed onto a drive shaft and fixed together with the tool of the holder. But this can also be achieved with annular elements.
- a plurality of annular elements can be placed on a drive shaft and separated, for example with spacers from each other and kept at a distance to each other.
- hollow cylinders, annular disks and circular disks can also be segmented, so that detection on and exercise of forces or moments in a preferred axial direction can take place.
- Such segments can form a closed hollow cylinder but also separate individual segments, which are held in a suitable form at a distance from each other.
- Circular disk-shaped or also formed as a circular disk segment elements can be arranged on end faces of tools or drive shafts to tion there, for example, between tool and holding tion as a result of the respective processing forces or moments to detect and close to the processing process sequence or actively influence the clamping position of the tool to be able to take relief.
- the entire clamping force can be changed but also the clamping force effect can be varied in preferred axes if a plurality of elements are arranged in a suitable form.
- the respective detected state can thus represent an image of the respective instantaneous process parameters resulting from time-varying forces and movements of tool and holder (clamping).
- the condition of tools which can affect, for example, their clamping conditions or the wear of tools, can also be recorded and then taken into account.
- Point of intervention of a tool which can then be corrected upon detection of a difference to a default or taken into account in the further control of the feed.
- State variables can also be determined when a tool is not engaged, ie during "idling".
- FIG. 1 shows an example of a holder according to the invention
- FIG. 2 shows another example modified in comparison with the example according to FIG.
- a holder 4 for a circular saw blade, as a tool 2 is present.
- the circular saw blade 2 is fixed by means of a holder, which is formed from two individual elements which can be clamped together. These practice one Compressive force from both sides on the circular saw blade 2 off.
- Holder 4 and circular saw blade 2 are mounted on a drive shaft 3 and rotate together about their axis of rotation.
- a module 1 formed in the form of element 1 is added. This is hollow inside and also pushed onto the drive shaft.
- the element 1 is at the radially outer periphery in touching contact with the inner bore of the circular saw blade 2, so that acting forces and / or moments in both directions, ie from the circular saw blade 2 to the element 1 or vice versa can be transmitted.
- a contacting which is connected to an electronic control of a machine, is present on element 1 in a manner not shown.
- elements 1 can form a module. This can, as explained in the general part of the description, be formed in different shapes, including several segments. These can be arranged distributed radially over the circumference or also in the direction of the longitudinal axis. However, it is also possible to embed elements 1 of a multifunctional material in a matrix of another material, which then should preferably be elastically deformable and only the task of positioning elements 1 in relation to holder 4 and tool 2, and optionally also that of an electrical insulation can take over.
- the element 1 is supported on one side with one end face on the holder 4 and on the other end side on the circular saw blade 2, so that acting forces and also vibrations can be detected and exerted.

Abstract
L'invention concerne des fixations d'outils d'usinage par coupage et/ou enlèvement de copeaux. Cette fixation peut être utilisée dans la construction de machines-outils classiques mais aussi dans d'autres domaines. L'invention vise à proposer des solutions qui permettent de mieux agir directement sur l'usinage par coupage et/ou enlèvement de matière dans le processus d'usinage. Ainsi au moins un élément, placé sur ou bien logé dans la fixation selon l'invention, permet de détecter les trajets modifiés, les forces ou couples exercés et de les appliquer sur un outil. En outre, les dérivées temporelles de trajets et/ou de forces modifiés, peuvent être déterminées et prises en compte par la création d'une référence temporelle.
