Description of the drawings
By exemplary implementation scheme and the present invention will be described in greater detail with reference to the attached drawings now, in the drawings：
Fig. 1 shows tight for tightening two or more screw threads by the power operated wrench of two or more artificial supports
The critical piece of the system of firmware；
The schematic diagram of Fig. 2 units in order to control.
Specific implementation mode
In fig. 1 it is shown that for by synchronize tighten threaded fastener by pre-tighten it is tight including two or more screw threads
The system 1 of the fastener 13 of firmware 11a-c.The system shown in Fig. 1 includes three artificial supports and is battery powered dynamic
Torque wrench 10a-c will be applied on multiple threaded fastener 11a-c.Threaded fastener 11a-c is the component of fastener 13,
Two of which element 14,15 will be combined by the chucking power obtained by threaded fastener 11a-c.Preferably, power
Spanner 10a-c is that torque pulse transmits type, does not generate any reaction force, allows the operator to operate two simultaneously and pull
Hand.But power operated wrench 10a-c may be that torque transmits type.Each in power operated wrench 10a-c not only carries detachably
Battery case, also carry unshowned interior arrangement, described device is used to indicate the reality such as output torque, angle displacement
Border operation data.These features are known in the prior art, therefore do not further illustrate herein.
Each in power operated wrench 10a-c includes wireless communication module 16a-c, the operation and control list for being used for and sharing
Member 18 communicates.Due to for equipped with the battery powered power operated wrench of wireless communication provide operation control unit itself be it is well known,
Therefore this feature is not explained in more detail.
In fig. 2, it is schematically shown control unit 18.Control unit 18 includes control loop and comparison loop；Institute
It states control loop and is suitable for actually tightening the operation data of operation and be programmed, and made to each power by the comparison loop
The control data that spanner is sent out are adapted to the practical operation data received from other power operated wrenches.Control loop and comparison loop can
For example to implement by being connected to processor 20 of memory 22, computer program is stored on the memory 22, institute
State computer program makes control loop and comparison loop carry out above-mentioned task when being executed by the processor.According to one
Embodiment, control unit 18 are further arranged to the reality of each in identification spanner during tightening process (sequence)
Border state, other power operated wrenches or multiple spanners are controlled to be corresponded to it tightens operation, and tightens spiral shell via synchronizing
Line fastener 11a-c and complete scheduled to tighten process (sequence).Control unit 18 is provided with wireless communication module 24, institute
Wireless communication module 24 is stated to be suitable for each power operated wrench 10a-10c wireless transmission data, or from each power operated wrench 10a-10c
Wireless receiving data.Wireless communication module can be operably coupled to control loop.It is tightened by this synchronize, in fastener
Equally distributed chucking power is obtained at 13, this is especially important to the fastener of the deformable sealing element with forms such as liners
(for the fastener, it is necessary to avoid the uneven setting of this element).
The present invention alternative embodiment in, operation control unit can be originally in by being located at power operated wrench or
It is formed in the internal individual control unit 18 of power operated wrench itself, it means that by every in individual control unit 18
The identification of one operation data and other power operated wrench current states is received and compares in a distributed fashion.This arrangement
Help to realize more flexible system.
The synchronizing of threaded fastener 11a-c is tightened can be continuous well or to be executed stepwise, as long as passing through power operated wrench
Each operation of tightening carried out in 10a-c is consistent with the operations of other power operated wrenches, with the realization at fastener 13
Equally distributed chucking power.
Alternatively, if multiple power operated wrenches are used to pre-tighten the fastener of more fasteners, multiple spanners can be grouped
Setting；The power operated wrench for tightening to control one group while from there through relative to power operated wrench in another group or other groups
Operation is tightened simultaneously and can be synchronized and be tightened.In this case, this synchronize the purpose tightened also in fastener at
Obtain equally distributed chucking power.
By a kind of system of offer, (system passes through with the channel radio for being communicated at least one operation control unit
Believe two or more battery powered power operated wrenches of module and synchronize the multiple threaded fasteners for tightening fastener), it can
Flexible fastener pretensioner systems are realized, without the adaptability and the relevant cable problem of operation with system.
