A system for pre-tensionmg a joint comprising a number of threaded elements,
Technical field
The invention relates to a system for pre-tensioning a joint comprising two or more threaded fasteners. In particular, the invention concerns a system in which two or more power wrenches are arranged to simultaneously tighten two or more threaded fasteners in a synchronized way in order to obtain an evenly distributed clamping force in the joint.
Background
In a system in which two or more power wrenches are arranged to simultaneously tighten two or more threaded fasteners in a synchronized way in order to obtain an evenly distributed clamping force in the joint there is conventionally used two or more power wrenches connected via cables to a common operation control unit to accomplish an individual control of each power wrench in relation to the operation of the other power wrench or wrenches to thereby obtain a synchronized tightening of the threaded fasteners and, hence an evenly distributed clamping force in the joint. While the existing systems work well, there is a constant desire to improve upon the existing systems.
Hence, there is a need for an improved system for pre-tensioning a joint comprising two or more threaded fasteners.

Brief description of the drawing
The invention will now be described in more detail by means of exemplary embodiments and with reference to the accompanying drawings, in which
Fig. 1 illustrates the main components of a system for tightening of two or more threaded fasteners by means of two or more manually supported power wrenches, and
Fig. 2 is a schematic view of a control unit.
Detailed description
In Fig. 1 a system 1 for pre-tensioning a joint 13 including two or more threaded fasteners 11a - c by a synchronized tightening of the threaded fasteners is depicted. The system illustrated in Fig. 1 comprises three manually supported and battery powered power wrenches 10 a-c which are to be applied on a number of threaded fasteners 11 a-c. The threaded fasteners 11 a-c are parts of a joint 13 wherein two elements 14, 15 are to be put together by a clamping force obtained by the threaded fasteners 11 a-c. Preferably, the power wrenches 10 a-c are of the torque impulse delivering type which do not generate any reaction forces, which makes it possible for an operator to operate two wrenches at a time. But the power wrenches 10 a-c can also be of the torque delivering type. Each one of the power wrenches 10 a- c carries not only a detachable battery casing but also a non- illustrated internal means for indicating actual operation data like output torque, angular displacement etc. These features are well known in prior art, and are therefore not further described herein .
Each one of the power wrenches 10 a-c comprises a wireless communication module 16a - c for communication with a common operation control unit 18. Since it is well known per se to provide battery powered power wrenches with equipment for wireless communication with an operation control unit that feature is not described in further detail.
In Fig. 2, the control unit 18 is schematically shown. The control unit 18 comprises a control circuit programmed with operation data suitable for the actual tightening operation, and a comparing circuit by which the outgoing control data for each power wrench are adapted to the received actual operation data from the other power wrenches. The control circuit and the comparing circuit can for example be implemented using a processor 20 connected to a memory 22 on which a computer program is stored that when executed by the processor causes the control circuit and comparing circuit to perform the above tasks. The control unit 18 is in accordance with one embodiment further arranged to identify the actual status of each one of the wrenches during a tightening sequence to control the tightening operation of the other power wrench or wrenches in response thereto, and to complete the predetermined tightening sequence via a synchronized tightening of the threaded fasteners 11 a-c. The control unit 18 is provided with a wireless
communication module 24 adapted to wirelessly transmitting and receiving data to/from the respective power wrenches 10a - 10 c. The wireless communication module can be operatively connected to the control circuit. By such a synchronized tightening there is obtained an evenly distributed clamping force in the joint 13, which is particularly important at joints having deformable sealing elements in the form of gaskets or the like where it is essential to avoid an uneven setting of such elements.
In an alternative embodiment of the invention the operation control unit may be formed by separate control units 18 located at or inside the power wrenches themselves, which means that operation data and identification of the present status of the other power wrenches are received and compared by each one of the separate control units 18 in a distributed manner. This arrangement will contribute to an even more flexible system.
The synchronized tightening of the threaded fasteners 11 a-c may very well be executed continuously or in steps as long as the tightening operation performed by each one of the power wrenches 10 a-c is kept up with the operation of the other power wrenches to accomplish an evenly distributed clamping force in the joint 13.
Alternatively, if a number of power wenches are used for pre- tensioning a multi-fastener joint the wrenches could be arranged in groups, whereby a synchronized tightening could be performed by controlling a simultaneous tightening operation of the power wrenches of one group in relation to a simultaneous tightening of the power wrenches in another group or groups. In this case too, the synchronized tightening aims to obtain an evenly distributed clamping force in the joint.
By providing a system for synchronized tightening of a number of threaded fasteners of a joint by two or more battery powered power wrenches having wireless communication modules for communication with at least one operation control unit it is possible to accomplish a flexible joint pre-tensioning system with no cable related problems as to the adaptability and operation of the system.
