Definitions

  • the invention relates to a method for rotating a rotatable member using a driven by a hydraulic pressure source hydraulic piston cylinder drive with at least one piston and a hydraulic cylinder and a ratchet, wherein during a load stroke, a torque applied to the rotatable member and the piston via a return stroke in a Starting position is moved.
  • a method for rotating a rotatable part is known in particular in the operation of hydraulic power wrenches.
  • a method according to the preamble of claim 1 shows the GB 2 449 638 ,
  • both methods include a method step in which a defined torque is applied to the part to be rotated.
  • a torque sensor is provided for measuring the torque applied to the part to be rotated.
  • Such a method is for example from the WO 03/013797 A1 previously known.
  • the provision of additional torque sensors is an additional expense and has the consequence that only certain types of power wrenches are suitable for carrying out the method.
  • such sensors are arranged on the power wrench itself, which is thereby sensitive to pollution and environmental influences. Since power wrenches are often used on construction sites, the aforementioned sensitivity to environmental influences and contamination is to be regarded as particularly disadvantageous.
  • the power wrenches are automatically controlled by a controller, upon reaching the pressure corresponding to the desired torque, the pressure source is automatically switched off or a phase of the angle-controlled rotation is initiated.
  • the controller can not recognize that the applied pressure is exerted only on the end stop and not a transfer of the Pressure on the rotatable part takes place. Therefore, even with such an automatic control, a visual inspection by the operator is necessary.
  • the gradients to be evaluated become even with identical systems, i. identical hose lengths and volumes of the piston-cylinder units, influenced by parameters of the parts to be rotated, so that a pressure gradient-based control of the pressure source can react unambiguously in different applications.
  • the inventive method is characterized in that the load stroke ends when reaching an end position and then the return stroke is initiated, wherein the end position is a position of the piston before striking the piston to an end stop.
  • the pressure exerted by the pressure source via the piston cylinder drive and the ratchet always on the rotatable part in the form of a Torque is transmitted.
  • the control of the hydraulic pressure source can thus turn off upon reaching a predetermined pressure, which is determined by the known system component or a previous calibration, and it is ensured that this pressure has actually been impressed in the form of a torque on the rotatable member.
  • the inventive method can avoid this mechanical stress in the use of the piston cylinder drive, resulting in a longer service life of Piston cylinder drive leads.
  • the method according to the invention makes possible a control which is independent of the actual chronological course of the pressure during a load stroke. Thus, such control will not be affected by unpredictable pressure gradient changes that may occur during rotation of a rotatable member in the load stroke, for example, by clutches, seating, seizure or changes in friction values. The reliability of the control is thus increased.
  • the return stroke can be done either by pressurizing the piston with hydraulic fluid or via a return element, for example a spring.
  • ratchet in the context of the invention is basically understood an element for force or torque transmission, which runs free in one direction and transmits in the opposite direction by force or positive engagement of the force or torque.
  • the determination of the instantaneous position of the piston with the travel of the piston is made possible in a simple way to determine the reaching of the end position of the piston and to end the load stroke.
  • the determination of the position can take place continuously or at intervals of time.
  • the travel during the load stroke is determined by the volume of hydraulic fluid supplied to the hydraulic cylinder. This is done by the volume and the known geometry of the hydraulic cylinder can be converted into the travel.
  • the volume of hydraulic fluid supplied to the hydraulic cylinder during the return stroke is determined.
  • the travel path determined during the preceding load stroke can be checked so that malfunctions in the control of the pressure source can be avoided.
  • Checking the travel path during the load stroke allows the detection of malfunctions in which the piston has been moved past the intended end position and against the end stop.
  • the inventive method can avoid unnoticed that the controller stops the pressure source, although the predetermined torque has not yet been impressed on the rotatable member.
  • the volume supplied to the hydraulic cylinder is determined by the temporal pressure curve of the hydraulic pressure source.
  • a pressure / volume flow characteristic can be determined, so that over the temporal pressure curve, the currently funded volumes can be summed up to the total volume delivered.
  • Such a method according to the invention has the particular advantage that no further sensor is necessary for carrying out the method according to the invention, since a pressure sensor is already present for determining the impressed torque. In particular, no additional sensor to the piston cylinder drive is necessary, whereby the complexity and susceptibility of the system is reduced.
  • the volume supplied to the hydraulic cylinder during the load stroke is determined via a volume flow measurement of the hydraulic fluid.
  • a volumetric flow measurement can be carried out by conventional volumetric flow measuring methods, for example in the hydraulic line between the piston cylinder drive and the pressure source. In volumetric flow measurement, the volume supplied to the hydraulic cylinder can be determined in a simple manner.
  • the volume of hydraulic fluid supplied to the hydraulic cylinder during the return stroke is determined via a volume flow measurement of the hydraulic fluid or over the time profile of the hydraulic pressure source.
  • the end position of the piston is detected by a sensor. Via a sensor, the end position of the piston can be determined very accurately.
  • the detection over a sensor may alternatively or additionally to the detection of the end position via the travel of the piston.
  • the sensor on the piston cylinder drive forms a higher cost and a higher susceptibility to external influences, but also means a higher accuracy of the method according to the invention.
  • the provision of a sensor on the piston-cylinder drive can therefore be advantageous.
  • the sensor may be an electronic sensor, an optical sensor or a Hall sensor.
  • the sensor can be used, for example, as a limit switch.
  • the delivery volume of the pressure source for a return stroke is greater than the volume of hydraulic fluid necessary for a piston movement from the end position of the previous load stroke to the starting position. This can ensure that the piston is moved into the starting position during the return stroke, so that a malfunction can be avoided in a subsequent load stroke.
  • the delivery volume of the pressure source for a return stroke can be specified as a function of the volume actually supplied to the hydraulic cylinder in the preceding load stroke or of the volume to be supplied by calibration during a load stroke prior to a single operation.
  • the end position of the piston is arranged at a distance D from the initial position of the piston, which is 85% -95%, preferably 90%, of the distance D between the initial position of the piston and the end stop.
  • the load stroke is only 85% -95% of the maximum achievable with the piston cylinder drive stroke.
  • known system properties of a control of the pressure source can be specified.
  • known system components such as a known hydraulic line, and a known piston-cylinder drive
  • control of the corresponding volumes and a system behavior can be specified, so that, for example, pressure-dependent volume changes can be considered as correction volumes.
  • system properties are determined by the repeated performing maximum piston strokes without concern of a load and return strokes, the maximum piston strokes of the starting position of Piston until the piston stops against the end stop.
  • necessary system properties such as volume of the hydraulic lines and volume of the piston cylinder drive and pressure-dependent volume changes can be determined by stretching the hydraulic lines and taken into account in the control of the pressure source.
  • the method according to the invention can be used in a particularly advantageous manner, since a pressure source with a controller can be used on different systems, without requiring a complex adaptation of the controller.
  • the method according to the invention for rotating a rotatable part using a hydraulic piston-cylinder drive operated by a hydraulic pressure source can be carried out, for example, with a power screwdriver for turning a screw.
  • a power wrench 10 is shown.
  • This has a hydraulic piston cylinder drive 11 with hydraulic cylinder 12 and a piston 13 movable therein.
  • the piston 13 is connected to a piston rod 14 and the end of the piston rod 14 engages a lever 15, which engages with a latching pawl 15 a on the toothing of a ratchet wheel 17.
  • the ratchet wheel 17 is part of a ring piece 18 which has a socket 19 for attaching a key nut or a screw head to be rotated. By reciprocating movement of the piston 13, the ring piece 18 is rotated and with this the screw.
  • the ring piece 18 is mounted in a housing 20 which also contains the piston cylinder drive 11.
  • the pressure for the piston cylinder drive 11 is supplied by a pressure source 25, which in the in Fig. 1 illustrated embodiment is designed as a hydraulic unit.
  • the hydraulic unit has a positive displacement pump 26 containing a motor and a tank.
  • the pressure source 25 is connected to the pressure line 28 and a return line 29 connected. These two lines are connected via a control valve 30 to the piston-cylinder drive 11. By switching the control valve 30, the piston 13 can be moved either forward or backward.
  • a control unit 31 is provided for controlling the pressure source 25 and the control valve 30.
  • a pressure sensor 32 On the pressure line 28, a pressure sensor 32 is provided, which measures the hydraulic pressure P in the pressure line 28.
  • the pressure sensor 32 is connected via a line 33 to the control unit 31.
  • hydraulic fluid is conveyed through the pressure line 28 via an inlet 28a into a first space 12a of the hydraulic cylinder 12.
  • the piston rod 14 in this case exerts a force on the lever 15, which converts the force into a torque which is impressed on the rotatable part, for example a screw.
  • the piston-cylinder drive 11 thus performs a load stroke, wherein the direction of the load stroke in Fig. 2 is shown by an arrow.
  • the ratchet wheel 17 is locked, so that the torque can be transmitted to the rotatable part.
  • the controller 31 terminates the load stroke and initiates the return stroke.
  • hydraulic fluid is conducted via the pressure line 28 through the outlet 29a into the second space 12b, so that the hydraulic fluid in the first space 12a moves from the piston 13 through the inlet 28a into the second chamber 12b
  • Return line 29 is pressed.
  • the piston 13 exerts a movement counter to the load lifting direction, wherein a tensile force is exerted on the piston rod 14.
  • the piston rod 14 pulls during the return stroke the lever 15 with it, the detent pawl 15 a free running.
  • the piston is in a position in which the piston is not yet struck at the end stop.
  • the method according to the invention provides that during normal operation the piston 13 does not abut the end stop 16. It is thereby achieved that the hydraulic pressure P measured by the pressure sensor on the pressure line 28 is completely converted, taking into account the usual correction values, into a torque which is exerted on the rotatable part. In other words, via the measured hydraulic pressure P, the torque impressed in the rotatable part can be determined, wherein it is avoided that the measured hydraulic pressure P is falsified by abutment of the piston 13 against the end stop 16.
  • the end position of the piston 13 can be determined by determining the instantaneous position of the piston 13 over the travel of the piston during the load stroke. When the end position is reached, the control unit then switches the control valve 30 to initiate the return stroke.
  • the travel of the piston 13 can be determined during the load stroke by the hydraulic cylinder 12 supplied volume of hydraulic fluid.
  • the volume of hydraulic fluid supplied to the hydraulic cylinder 12 can be determined, for example, by means of the temporal pressure profile of the hydraulic pressure source 25, wherein the chronological pressure profile of the hydraulic pressure source 25 can be detected with the aid of the pressure sensor 32.
  • a pressure / volume flow characteristic obtained from a calibration of the system is necessary, so that the from the current pressure certain currently funded volumes can be added to the total volume funded.
  • the controller 31 Upon reaching the predetermined total volume, the controller 31 detects that the piston 13 is in the end position.
  • the volume of hydraulic fluid supplied to the second space 12b can also be determined.
  • the temporal pressure profile of the hydraulic pressure source 25 can also be used.
  • hydraulic cylinder 12 supplied volume of a hydraulic fluid is determined by a volume flow measurement.
  • the end position of the piston is detected by a sensor, which is used for example as a limit switch. Via the sensor, the controller 31 receives a signal to end the load stroke and initiate the return stroke.
  • the sensor can be used as an alternative or in addition to the determination of the end position over the travel of the piston 13.
  • the default of the hydraulic cylinder 12 supplied volume of hydraulic fluid is greater than the hydraulic cylinder supplied volume of the previous load stroke in that the delivery volume setting of the pressure source 25 is set correspondingly higher during the return stroke than during the load stroke.
  • the piston 13 is arranged in the end position at a distance d from the initial position of the piston 13, which is 85% -95% of the distance d between the initial position of the piston 13 and the end stop 16.
  • the load stroke is only 85% -95% of the maximum stroke that can be carried out with the piston-cylinder drive 11.
  • the maximum stroke of the hydraulic cylinder 12 is a stroke from the initial position of the piston 13 to the approach of the piston 13 to the end stop 16.
  • the avoidance of the abutment of the piston 13 to the end stop 16 also has the advantage that the piston-cylinder drive 11 is subjected to a lower mechanical load. Since high pressures are generated during the load stroke, a start of the piston 13 at the end stop 16 means a high mechanical load on the piston 13, which is avoided by the method according to the invention. During the return stroke, no such high mechanical loads on the piston 13 arise when it strikes against the second end stop 16a.
  • the method according to the invention uses a system which consists exclusively of known system components, such as a previously known power wrench with a previously known hydraulic piston-cylinder drive 11, and a previously known pressure line 28 and a previously known return line 29, the previously known system properties of the control of the pressure source 25 can be predetermined. These may for example already be stored in the control unit 31.
  • the system properties can be, for example, pressure-dependent volume changes of the lines.
  • the system properties can be determined by a calibration and taken into account in the control of the pressure source 25 accordingly.
  • the system properties are determined by repeatedly performing maximum piston strokes without concern of a load and return strokes.
