A corresponding actuator can also be equipped as an element that extends through material expansion.

Such elements which are actuatable protruding out of the sliding surface may also be used to hook into structures in the overlay. For example, in this case a pin can be actuated out of the sliding surface. If the support has a circular depression, then the pin can penetrate into this depression at a specific position of the processing aid and block further displacement of the processing aid. In this way, the processing aid can be fixed. If at least two such elements are provided, an orientation of the processing aid can also be fixed.

In this way, for example, a contacting of a tool with a workpiece can be detected when the workpiece and the tool are electrically conductive and a voltage is applied between the workpiece and the cantilever. As soon as the tool comes into contact with the workpiece, a current flows, which can be detected by the current sensor. Such an embodiment can also be used if a component is to be brought into contact with the workpiece in an assembly process. If the component is held by the tool and it is electrically conductive, the current flows as soon as the component is in contact with the workpiece.

The processing aid according to the invention can advantageously have at least one further arm, with which a tool can be guided. In this way, the boom for changing processing situations can be changed quickly without having to rebuild the editing aid itself. It is also possible, in particular, that at least one further Outrigger a tool is maintained, so that an operator can quickly change both tool and boom.

The production can be done, for example, by impression and / or layer construction techniques. Numerous other individual production methods are conceivable.

Optionally, the hand rest and the base plate can be realized as one part, ie monolithic. Also, the boom can optionally be monolithically formed with the palm rest and / or the base plate. However, it is advantageous if the hand rest, the base plate and the boom are three separate interconnected parts. The boom can advantageously be exchangeable.

According to the invention, a machining system is also specified, which on the one hand comprises a machining aid as described above and on the other hand a support on which the machining aid can be placed with its sliding surface.

If a user puts his hand in the channel 2, he can lean his palm on the stabilizer 3 or be supported with the outside hand on the stabilizer 4, for example. to avoid jarring. The stabilizers 3 and 4 are optional and can be implemented individually or together.

In order to follow the bending of the hand as described by palm and finger, the receptacle 2 is correspondingly curved around the inner hand stabilizer 3 with respect to a longitudinal direction of the channel 2. In the example shown, the palm rest is formed from an element having a circular base.

In the Fig. 1 Hand rest 1 shown has a lifting element 5 or a vibrating element 5 for haptic feedback to the editor. If a processor puts his hand in the channel 2, he touches the lifting element or vibrating element 5. To signal a specific state of processing, the lifting element may protrude from the surface 2 and abut the hand of the editor. As a vibration element 5, this element can impart a vibration to the hand of the user. The lifting element or vibration element 5 is optional, but can be implemented in all embodiments of the invention.

Im in Fig. 1 As shown, the processing aid has the base plate 8, the hand rest 1 and the arm 10. The hand rest 1 is arranged on the base plate 8. Both the hand rest 1 and the base plate 8 are designed with a circular circumference, wherein the centers of these circular circumferences are coaxial with each other. The boom 10 is disposed approximately along an extension of a passage direction of the receptacle 2 for the hand. What is meant is that direction which describes the hand edge of the user when he has his hand for intended use in the receptacle 2. In the example shown, the hand rest 1 is rotatable relative to the base plate 8 about a passing through the center of the base plate and the hand receiving axis. A certain relative position of the hand rest 1 and the base plate 8 to one another can be detected by means of a locking device 19.

Side edges of the boom 10 have a corrugation with which a tool 27 (in Fig. 4 shown) is feasible.

In order to enable a possible friction-smooth sliding of the processing device on a support, 8 sliding elements 11 are arranged in the sliding surface, which may be, for example, plain bearings. Such plain bearings 11 may be formed for example by balls in corresponding receptacles in the sliding surface. In order to prevent tilting of the processing aid, preferably three of the processing elements 11 are provided, which are arranged at corners of an equilateral triangle. The sliding elements 11 are also optional, but may be implemented in all embodiments of the invention. Alternative sliding possibilities are conceivable, for example by a simple polishing of the sliding surface 9.

If at least two signal transmitters and two signal receivers 15 are provided, an orientation of the processing aid can also be determined. Analogously, the elements 15 can also be signal receivers. In this case, signal transmitters are arranged in a corresponding manner in the support. In the example shown, the elements 15 are diametrically opposite with respect to a center of the circular sliding surface 9. The signal generator or signal receiver 15 are optional, but can be implemented in any embodiment of the invention.

Im in Fig. 2 In the example shown, two diametrically opposed centering aids 16 are also arranged in the sliding surface 9 with respect to the center of the sliding surface 9. These may, for example, have pins that protrude perpendicularly from the sliding surface 9. The pins can be actuated for this purpose.

In that of the base plate 8 facing away from the bracket 10 has an opening 20 through which a tool 27 or a component 28 can be passed. Such a tool 27 is then rotatable about the opening and slidable in its longitudinal direction, but not in the plane of the boom 10 slidably. The tool is thus guided through the opening 20 and the boom 10. Alternatively, the opening 20 may also have another shape, for example the shape of a rectangle, at the edge of which the tool can be guided. The opening can be formed here as a template, for example.

Fig. 3F shows a further exemplary embodiment of the boom 10. The boom 10 is in this case elongated and has at its lateral edges notches, in which a tool for guiding can be inserted. In the example shown, the boom may be displaceable in the direction of its longitudinal direction. The displaceability can take place counter to a spring force or be actuated by a suitable actuator.

Fig. 4 shows a system according to the invention with a processing aid according to the invention and a support 30 on which the processing aid is moved. The support 30 extends here over the entire figure surface. In use, a user has placed his hand 26 in the palm rest 1 and the processing aid rests with the sliding surface 9 of the base plate on the support 30. The user holds in his hand 26, a tool 27, with which he attacks a screw 28 in the example shown. The tool 27 is a tweezers 27. The boom 10 is as in FIG. 3F As an alternative, however, it may also have a hook-shaped groove on its end facing away from the base plate. On the boom 10, the tool 27 can be performed to place the screw 28 just above a screw hole and screwed there. For positioning and orientation of the processing aid on the support 30, the support 30 signal generator 29a, 29b, 29c, 29d, 29e, which are designed here as light-emitting diodes. In the example shown, the signal generator 29a is active, ie it lights up while the others Signalers 29b to 29d are not active. The user can now move the processing aid until an arranged in the sliding surface 9 of the processing aid sensor for the light signal with the light source 29a is exactly in line. The processor can then be signaled by the possibilities described above that the said position is reached. By simultaneous activation of several of the signal generator 29, an orientation of the processing aid can be determined in a corresponding manner.
