    Therefore, it is an object of the present invention to provide a stationary tool with which the above-mentioned problems can be solved. In particular, a stationary tool should be provided, which is simpler and more cost effective to provide.
    This task is solved by a stationary tool according to claim 1.
    Advantageous additional designs of the stationary tool are set out in the dependent claims. In the case of the stationary tool, a wireless operation is possible, which facilitates the installation of the stationary tool, as no wiring is required. As a result, a simple replacement is also possible in the event of a fault.
    The term "stationary" in accordance with this application means a permanent installation of the tool on an object or place, such as a tool table, a robot, etc. The stationary tool is thus not held in the hand by the user when machining a workpiece.
    The workpiece must therefore be brought to the installation site of the stationary tool.
    This also applies in the case of an installation of the stationary tool on a robot, even when the robot can move the stationary tool within a certain circumference relative to the workpiece.
    The stationary tool forms a compact unit. No additional manufacturing equipment is required.
    An additional advantage of the stationary tool is that the stationary tool can be mounted directly on a robot, which can be used, for example, in a production plant, such as in a production line for vehicles, furniture, etc. The stationary tool is also useful in production in the aviation industry.
    The desktop tool can be used in combination with other wireless or wireless automation devices. This is particularly advantageous at production facilities.
    In addition, a secure machining of a workpiece is possible with the stationary tool, since with the data measured by a measuring device to the stationary tool one can check and, if necessary, adjust the machining of the tool accordingly. If the stationary tool is, for example, a stationary battery-powered screwdriver, a safe screwing is possible by the measuring device measuring torque and turning angle with a specific accuracy and evaluating if necessary. This allows presetting for the tightening to be followed.
    Further possible implementations of the invention also include non-explicitly mentioned combinations of the above-mentioned criteria or embodiments described with reference to the exemplary embodiments. The person skilled in the art also adds individual aspects such as improvements or additions to the current basic form of the invention.
    The invention is described in more detail below with reference to the accompanying drawings and with the aid of the exemplary embodiments. They show: Fig. 1 shows a schematic view of an external apparatus and a stationary tool according to a first embodiment: and Fig. 2 shows a schematic view of an external apparatus and a stationary tool according to a second embodiment; In the figures, identical or function-like elements, unless otherwise stated, are provided with the same reference numerals.
    Fig. 1 shows in a first embodiment a stationary tool 10 and an external device 30, which is externally arranged from the stationary tool 10. The stationary tool 10 and the external device 30 can communicate with each other via a data connection 40. In this case, data with with respect to an operation of the stationary tool 10 via the data link 40 is exchanged bidirectionally.
    In the present embodiment, the stationary tool 10 is a stationary screw tool or a stationary drill spindle. However, the stationary tool 10 may also be a stationary riveting tool, a stationary punching tool or another stationary tool. The external device 30 may be, for example, a personal computer, a tablet PC, a mobile phone, such as a smartphone, etc.
    In Fig. 1, the stationary tool 10 has an output shaft 11, a coupling shaft 12, a driven unit 13, a measured value recorder or a measuring device 14, a drive mechanism 15, a motor 16, a control device 17, a transmitter / receiver device 18, a capacitor 19, a battery electronics 20, a battery 21 and a connector 22.
    The control device 17 controls the stationary tool 10 during its operation. In this case, for example, the measured value device 14 of the stationary tool 10 measures data relating to the output shaft 11 and / or the coupling shaft 12. The data data indicate in particular a torque which is transmitted from the motor 16 by means of the drive mechanism 15 on the driven unit 13 and from there transmitted via the coupling shaft 12. the output shaft 11.
    The data data can also indicate an angle of rotation, around which the output shaft 11 will be rotated / rotated due to the operation of the motor 16.
    The data data can be transmitted with the transmitter / reception device 18 via the data connection 40 to the external device 30. The transmission can be initiated independently from the stationary tool 10 by means of the control device 17. However, the transmission can also take place due to an access of the external device 30. the external device 30 can send a corresponding instruction to the stationary tool 10 via the data connection 40. In addition, the data data can also be stored in a memory unit (not shown) belonging to the control device 17 at least until the data data has been successfully sent to the external device 30. In this way the data data stored at least temporarily. In addition, the external apparatus 30 can also preset setpoints for in particular torque, angle of rotation, etc., which the stationary tool 10 controlled by the control device 17 is to achieve.
    The measured value device 14 and / or the control device 17 can evaluate the data data if necessary. The result of the evaluation can be sent to the external device 30 in addition to the measured data.
    At the stationary tool 10, the transmitter / receiver device 18 is designed for wireless transmission or reception of the data data. For example, the transmitter / receiver device 18 may be an antenna for transmitting the data data via the data link 40 by radio. The transmitter / receiver device 18 may also be WLAN-operated.
    The battery 21 serves to supply the stationary tool 10 with electrical energy.
    The battery 21 of the stationary tool 10 may be a rechargeable or non-rechargeable battery.
    Preferably, the battery 21 is a rechargeable battery, such as an accumulator, as this reduces waste and is resource-saving. The battery 21 is controlled and monitored by the battery electronics 20.
    Thus, the stationary tool 10 is a wireless or wireless stationary tool 10. Thus, the stationary tool 10 no longer needs any cables. Due to the functions of the measuring device 14 and the control device 17, the stationary tool 10 can also be referred to as a wireless measuring stationary tool with integrated control. In the case of a drilling spindle, one can also speak of a wireless measuring stationary accumulator spindle with integrated control.
    The stationary tool 10 thus offers a complete solution with a stationary wireless or cable, with respect to electric current, data / signal and air, tools for process engineering fastening with determination, assessment and transmission of process data via an integrated control, the control device 17, with transmitter - / receiving device 18 such as WLAN radio module.
    In other words, the stationary tool 10 is, for example, an accumulator screw spindle for safer screwing. When screwing, ie during operation of the accumulator screw spindle, torque and turning angle are determined and evaluated with a specific accuracy. This process data is provided with a superior control, the control device 17. The control device 17 is arranged directly at the accumulator screw spindle, the stationary tool 10.
    The screw spindle can send directly to a network, which is represented by the data connection 40 and can be connected to a network, for example a local network, internet, etc.
    At the stationary tool 10, the transmitter / receiver device 18 is arranged directly at, in particular on, the control device 17. In the event of failure of the transmitter / receiver device 18 and / or the external device 30 and / or the data connection 40, all data can be stored and transmitted at a later time. Communication with other automation devices such as other external devices is also possible.
    Fig. 2 shows a second embodiment with the stationary tool 10, which in other parts is constructed in the same way, as described in the first embodiment. Also in the present embodiment, an external device 30 is present, which can communicate bidirectionally with the stationary tool 10 at the data link 40, as described in the first embodiment.
    In contrast to the first embodiment, the stationary tool 10 in the present embodiment also has a display device 25. With or on the display device 25 the data data can be displayed, which have been measured by the measuring device 14. In addition, with or on the display device 25, for example, data regarding the battery 21 charge state. the operating hours of the stationary tool 10, etc. is shown.
    Thus, a direct operation and / or condition monitoring of the stationary tool 10 is possible. In particular, the display device 25 can display live data with respect to the stationary tool.
    Otherwise, the stationary tool 10 is constructed in the same manner as in the first embodiment.
    All the above-described designs of the device 10 and its method can find use separately or in all possible combinations. In particular, all the criteria and / or functions according to the embodiments described above can be arbitrarily combined.
    In addition, the following modifications in particular are conceivable.
    The parts shown in the figures are schematically represented and may in the exact design deviate from the shapes shown in the figures, as long as their functions described above are guaranteed.
    The battery 21 can be similarly constructed as a battery for a hand tool.
    The measuring device 14 can be similarly constructed as a measuring device for a hand tool. The transmitter / receiver device 18 may be similarly constructed as a transmitter / receiver device for a hand tool. In this way, already available parts can be used, whereby a development cost is saved and the logistics for the supply of different parts are simplified.
    Thus, a kit can be provided which is suitable for both the realization of a measuring accumulator hand screwdriver and for the realization of a measuring accumulator screw spindle. The measuring accumulator hand screwdriver additionally has a handle and possibly an angular output gear. The lens unit for storing the data data measured by the measuring device can also be arranged externally from the control device 17 at the stationary tool 10.
    The arrangement of the parts of the stationary apparatus 10 in Fig. 1 and Fig. 2 is only one of arbitrarily many possibilities. The arrangement of the parts is arbitrarily selectable, as long as the functions described above are guaranteed.
