Definitions
- the present invention relates to a control method for an impact wrench for fastening steel components by means of screw connections.
- the control method of the invention includes two modes of operation that are performed in response to a position of a selector switch.
- the first operating mode involves the following steps:
- first strokes of the hammer on the anvil Capture the event of a blow of the hammer on the anvil with a shock sensor; Detecting an angular position of the anvil with an angle sensor; Estimate a single beat angle of the anvil by the most recently detected beat based on the angular position of the anvil before the last detected beat and the angular position of the anvil after the most recently detected beat and comparing the single beat angle to a single beat target angle.
- the first operating mode is terminated when the single-stroke angle falls below a single-stroke target angle.
- the second operating mode provides the following steps: detecting the angular position of the anvil with the angle sensor as the starting position; Making second strokes of the hammer on the anvil; and detecting a relative angle of rotation of the anvil to the home position during the second strokes.
- the second mode of operation is terminated when the relative angle of rotation exceeds a standard angle.
- One embodiment provides during the second operating mode to detect a rotational movement of the machine housing with a rotational movement sensor and to determine the relative rotational angle based on the angular position of the anvil and the rotational movement of the machine housing.
- pivotal movements of the impact wrench are preferably taken into account by the user when determining the switch-off criterion.
- One embodiment provides that during the first operating mode, following the undershooting of the single-stroke setpoint angle, a predetermined number of third blows are executed with the hammer. If a selected screw connection requires very low single-stroke setpoint angles, the method can be approximately completed at a higher single-stroke setpoint angle and supplemented by a fixed number N of punches.
- One embodiment provides to check whether a screw is to be tightened with the second operating method, regardless of the switching position of the operation selector switch. Before performing the second beats, at least one first beat may be performed, the single beat angle to the first beat determined, and compared to the single beat target angle. If the single-stroke angle exceeds the single-stroke target angle, the second operating mode is canceled. The screw connection and possibly adjacent screw connections are still not properly tightened with the first mode of operation.
- the setting of the screw connections can log the first operating mode and the second operating mode individually for each screw.
- Fig. 1 an impact wrench
- FIG. 1 shows schematically the structure of a impact wrench 1.
- An application of the impact wrench 1 is the screwing of a steel plate 2 on a steel beam 3.
- the steel plate 2 and the steel beam 3 are connected by a screw 4 and a nut 5 with each other.
- the typical steel plates and steel beams have undefined curved surfaces, which exert a counter force when screwed together like a steel spring.
- the impact wrench 1 supports the user in a secure screw connection.
- the steel plate should lie flat against the steel girder and the screw 4 should not be overstretched.
- the screw 4 or the nut 5 are tightened in two phases.
- the screw head of the screw 4 is fixed and the nut 5 is tightened.
- the nut 5 is tightened until the screw 4 is stretched to approximately 40% to 60% of its yield point.
- the elongation is not measured directly, but estimated by a single beat angle theta, around which the nut 5 rotates by a single beat. It has been found that for the targeted range of yield strength, i. 40% to 60%, the single-impact angle theta largely depends solely on the screw 4 and the nut 5, and are only a small amount of unknown stresses of the steel beam 3 and the steel plate 2.
- an upper limit is determined in trial series for each screw type, i. depending on diameter, length, thread pitch, material pairing of screw 4 and nut 5 etc.
- the nut 5 is tightened in the first phase until the single-stroke angle theta drops below the single-stroke target angle theta in a single stroke. If a plurality of screws for fixing the steel plate 2 are necessary, this first phase is performed for all of their nuts.
- a subsequent second phase the nut 5 is tightened until the screw 4 is stretched to approximately 70% to 80% of its yield point.
- the strain is not measured directly, but estimated by a relative rotational angle dphi of the nut 5 relative to the screw 4. It has been recognized that this strain can no longer be determined with sufficient accuracy by the single impact angle theta.
- the relative rotation angle dphi is a robust measure of the elongation.
- an upper limit (standard angle dPhibz) is determined in test series for each screw type, ie depending on diameter, length, thread pitch, material pairing of screw 4 and nut 5 etc. It may be advantageous to have the standard angle dPhi dependent on the total thickness of the steel beam 3 and the steel plate 2 set.
- the relative rotation angle is determined from the beginning of the second phase, for example set to zero at the beginning of the second phase.
- the nut 5 is tightened by turning around the standard angle dPhi.
- the stepwise tightening of the screw 4 proves to be tolerant to different stresses between the steel plate 2 and the steel beam 3. A possible overstretching of the screw 4 by a single-stage tightening up to a predetermined torque can be avoided here.
- the impact wrench 1 has an electric motor 7, a striking mechanism 8 and an output spindle 9.
- the striking mechanism 8 is continuously driven by the electric motor 7.
- a retroactive torque M of the output spindle 9 exceeds a load value MO
- the percussion mechanism 8 exerts periodic impacts on the output spindle 9 with a short-term but very high torque.
- the output spindle 9 rotates accordingly continuously initially and then stepwise about a working axis 10.
- the electric motor 7 can be powered by a battery 11 or mains powered.
- the impact wrench 1 has a handle 12, by means of which the user can hold and guide the impact wrench 1 during operation.
- the handle 12 may be rigid or mitttels damping elements attached to a machine housing 13.
- the electric motor 7 and the striking mechanism 8 are arranged in the machine housing 13.
- the electric motor 7 is switched on and off by means of a button 14.
- the button 14 is for example arranged directly on the handle 12 and operable by the hand surrounding the handle.
- the impact wrench 1 has an operation selector switch 15 for switching between a first operation mode and a second operation mode.
- the exemplary striking mechanism 8 has a hammer 16 and an anvil 17.
- the hammer 16 has claws 18 which rest in the direction of rotation on jaws 19 of the anvil 17.
- the hammer 16 may transmit continuous torque or momentary angular momentum to the anvil 17 via the claws 18.
- a coil spring 20 tightens the hammer 16 toward the anvil 17, whereby the hammer 16 is held in engagement with the anvil 17. If the torque exceeds the threshold, the hammer 16 shifts against the force of the coil spring 20 until the claws 18 are no longer in engagement with the anvil 17.
- the electric motor 7 can accelerate the hammer 16 in the direction of rotation until the hammer 16 is again forced into engagement with the anvil 17 by the helical spring 20.
- the kinetic energy gained in the meantime is transmitted by the hammer 16 to the anvil 17 in a short impulse.
- One embodiment provides that the hammer 16 is forcibly guided on a drive spindle 21 along a spiral path 22.
- the positive guidance can be realized, for example, as a helical depression in the drive spindle 21 and a pin of the hammer 16 engaging in the depression.
- the drive spindle 21 is driven by the electric motor 7.
- the output spindle 9 protrudes from the machine housing 13.
- the protruding end forms a tool holder 23.
- the tool holder 23 has a square cross-section.
- a socket 24 or similar tool can be plugged onto the tool holder 23.
- the socket 24 has a socket 25 with a square hollow cross-section, which essentially corresponds in its dimensions to the tool holder 23.
- the socket 25 opposite the socket 24 has a mouth 26 for receiving the hexagonal screw 4 or a hexagonal nut.
- the impact driver 1 has a shock sensor 27 for detecting shocks.
- the impact sensor 27 is, for example, an acceleration sensor 28 or a microphone.
- the beating leads to a vibration of the impact wrench 1 with a characteristic signature. For example, the amplitude of the detected acceleration or the volume of the detected sounds can be compared to a limit value.
- the impact sensor 27 includes an evaluation of the power consumption of the electric motor 7.
- the power consumption shows the impact of the hammer 16 on the anvil 17 a characteristic short-term jump in power consumption.
- the impact sensor 27 may, for example, filter the signal of the power consumption by means of a high-pass filter and compare it with a limit value. Instead of or in addition to the power consumption, short-term changes in the rotational movement of the hammer 16 or the electric motor 7 can be detected. During the impact, for example, the rotational speed U of the electric motor 7 decreases for a short time.
- the impact wrench 1 has an angle sensor 29 for detecting an angular position phi of the anvil 17 and the tool holder 23.
- the angle sensor 29 can directly detect the angular position phi of the anvil 17. For example, optically detectable markings, for example grooves, can be embossed on the anvil 17.
- the angle sensor 29 is based on an optical sensor which detects the markings.
- the angle sensor 29 can estimate the progress of the angular position phi of the tool holder 23. For example, the angle sensor 29 estimates the angular position phi based on the rotational movement of the drive spindle 21 during the period between two impacts.
- the hammer 16 and the anvil 17 were in the meantime exactly once out of engagement.
- the anvil 17 does not rotate during the missing procedure.
- the next engagement occurs when the jaws 18, 19 are again rotated to an engaged position.
- These positions are typically offset by the angular distance of the jaws 18 of the hammer 16 to each other. Accordingly, the anvil 17 has rotated by this angular distance less than the hammer 16 during the period between two beats.
- the rotational movement of the hammer 16 can be detected directly on the hammer 16, the drive spindle 21 or indirectly on the electric motor 7.
- the device controller 30 detects the position of the operation selector switch 15.
- the device controller 30 executes a first operation mode or a second operation mode according to the position of the operation selector switch.
- the first operating mode may begin with an optional pre-phase.
- the screw 4 is rotated continuously.
- the impact wrench 1 rotates the tool holder 23 at a continuous rotation speed U which is equal to the rotation speed Uh of the hammer 16 (step S1).
- the speed U can be specified by the user via the button 14 or can be stored as a predetermined size in the device control 30.
- the impact wrench 1 can lower the rotational speed Uh of the hammer 16 in order to suppress striking of the striking mechanism.
- the lowering of the speed Uh can be up to a minimum value.
- An angular position phi of the tool holder 23 increases continuously. The continuous turning allows a high working speed.
- the impact driver 1 stops the continuous rotation of the tool holder 23 as soon as the retroactive torque M on the tool holder 23 exceeds a predetermined load value MO (step S2).
- the impact wrench 1 automatically changes into a beating operation.
- the change is preferably realized by the mechanical structure of the impact wrench 1.
- the load value MO is given in the exemplary impact wrench 1 by the spring strength of the coil spring 20 and the inclination of the web 22.
- the load value MO can be varied for example by an adjustable bias of the coil spring 20.
- the impact wrench 1 beats the hammer 16 repeatedly in the direction of rotation 31 on the anvil 17 (step S3).
- the angular position phi of the tool holder 23 now changes discontinuously, i. gradually.
- the anvil 17 rotates through each individual stroke by a single impact angle theta in the direction of rotation 31. Between the blows the anvil 17 rests.
- the single impact angle theta is dependent on the counter-torque of the nut 5.
- the impact energy is preferably constant.
- the counter torque of the nut 5 increases with the tightening of the nut 5, therefore, the single-turn angle ⁇ decreases.
- the single-impact angle theta can decrease uniformly and monotonically. However, jumps can also result in the single-turn angle theta.
- an intermediate increase in the single-turn angle theta is possible, for example, when the steel plate 2 relaxes.
- the time to the impact events H1, H2, Hn of a beat is a priori indeterminate.
- the single-stroke angle theta is detected for each individual stroke.
- the beat sensor 27 detects when or when a strike occurs (step S4).
- the angle sensor 29 continuously detects the angular position phi of the anvil 17 (step S5).
- the apparatus controller 30 determines the single-shot angle ⁇ of the anvil 17 by each beat (step S6) based on the angular position phi before and after each beat.
- the single shot angle theta is compared with a single beat target angle theta (step S7). As soon as the single-turn angle theta drops below the single-stroke setpoint angle theta, the first operating mode changes.
- the impact wrench 1 terminates the first mode of operation and deactivates the electric motor 7.
- a fixed number N of strokes is performed (step S8).
- the number N is between 5 beats and 20 beats.
- the beating with a fixed number N is particularly advantageous when the predetermined by the screw 4 single-stroke target angle theta is below the resolution limit of the available sensors. It was recognized that in this case from the already achieved bias a fixed Number N of impacts is more robust against a priori unknown influences, eg compared to the relative rotation angle dphi.
- the impact wrench 1 ends the first operation mode and deactivates the percussion mechanism 8, for example, by switching off the electric motor 7 (step S9).
- the single-stroke setpoint angle ⁇ and possibly the fixed number N of strokes can be stored in a memory 32 for different fastening elements 4.
- the user selects the fastening element 4 via an operating element 33 on the impact wrench 1 or an external console 34 communicating with the impact wrench 1.
- the apparatus controller 30 adjusts the single-shot target angle ⁇ and possibly the fixed number N of strokes for the first-phase control method according to the user's choice.
- the second operating mode or second phase can begin with an examination of the already achieved elongation. For example, impact wrench 1 strikes a few times, e.g. once to three times (step S11). The impact wrench 1 detects the single-stroke angle theta (step S12). Detecting the single beat angle theta can be done as described above. The single shot angle theta is compared with the single stroke target angle theta (step S13). If the single-shot angle theta does not fall short of the given single-stroke target angle theta, the apparatus controller 30 aborts the second operation mode and issues a warning to the user (step S14). The user is preferably prompted to tighten the screws according to the first mode of operation. If the single-stroke setpoint angle theta is undershot, the actual second operating mode begins.
- the current angular position phi of the anvil 17 is detected and stored as the starting position Phi (step S15).
- the initial position Phi is preferably detected prior to the test to detect the rotation performed by the test for the subsequent process.
- the impact wrench 1 applies impacts to the anvil 17 (step S16).
- the angle sensor 29 detects the current angular position phi of the anvil 17 (step S17).
- the current angular position phi is continuously compared with the starting position Phi.
- the current relative rotational angle dphi is determined based on the starting position Phi. For example, the relative rotational angle dphi is simply the difference between the actual angular position phi of the anvil 17 and the starting position Phi.
- the current relative rotation angle dphi is compared with the standard angle dPhi.
- the device controller 30 stops the hammer mechanism 8, for example, by deactivating the electric motor 7 (step S19).
- the screw 4 is now tightened to the final elongation.
- proper movements of the impact wrench 1 in particular a rotational movement about the working axis 10, can be neglected to a good approximation.
- the estimation of the single beat angle theta is sufficiently independent of the typically occurring, usually slow proper motions.
- the proper motion can have an effect on the strain.
- the achievable relative rotation of the screw 4 relative to the nut 5 is equal to the current angular position phi of the anvil 17 relative to the machine housing 13 only at a dormant impact wrench 1.
- the impact wrench 1 advantageously detects during the second phase rotational movements of its machine housing 13 relative to the room.
- the impact wrench 1 has, for example, a rotational movement sensor 35 for determining an angular velocity about the working axis 10 based on the Coriolis force or an acceleration sensor for determining rotational accelerations about the working axis 10.
- the device control 30 determines based on the rotational movement an angle omega, around which the impact wrench. 1 has rotated around the working axis 10.
- the current angular position phi of the anvil 17 is corrected by the angle omega (step S20).
- the standard angle dPhi can be stored in a memory 32 for various fastening element 4.
- the user selects the fastening element 4 via an operating element 33 on the impact wrench 1 or a console 34 external to the impact wrench 1.
- the device controller 30 adjusts the standard angle dPhi for the second phase control method according to the user's choice.
- the external console 34 has an interface 36 for wireless communication, which can communicate with a corresponding interface 37 of the impact wrench 1.
- the external console 34 includes, for example, the database 38 with the parameters such as single target angle theta and standard angle dPhi for different fasteners, screws, etc.
- the external console 34 may be realized, for example, by a software application on a conventional mobile device, eg smartphone .
- the tightening of the screw 4 with the first operating mode and the second operating mode is preferably automatically recorded for each screw 4.
- the protocol records the time at which a screw 4 with the first Operating mode and on which the screw 4 was tightened with the second operating mode.
- the impact wrench 1 can assign the protocol to the individual screws, for example, based on their position in space.
- a tracking device 39 detects the position of the impact wrench 1 in the space, which is substantially equal to the position of the screw 4 in the room.
- the tracking device 39 can communicate via a wireless interface 40 with a corresponding interface 37 of the device controller 30. Alternatively, the tracking device 39 transmits the position to external console 34.
- a database 38 for recording the protocol may be provided in the impact wrench 1 or in the console 34.
