Fast machine drives chuck to rotate again, so as to complete the connection between two pipe fittings.The setting of reductor and shaft coupling can reduce electricity
The rotating speed of machine, moment of torsion is improved, so as to provide condition for the connection of pipe fitting.
Further set：Electric-control system is additionally provided with the frame, electric-control system electrically connects with torsion torque sensor, for connecing
Receive the signal that torsion torque sensor is sent and open or close motor.
By using above-mentioned technical proposal, the torsion in torsion torque sensor detection work, set for different size pipe fitting
Corresponding torsion, is stored in electric-control system.When torsion reaches pre-set value in work, torsion torque sensor transmits signals to automatically controlled
System, electric-control system, which sends command job process, to be terminated.Pretension terminates, and removes passive pipe fitting, active pipe fitting, whole assembly pretightening
Process terminates.
Further set：Displacement transducer is additionally provided between pipe casting clamp and active cell in the frame.
By using above-mentioned technical proposal, the setting of displacement transducer can be sensed between pipe casting clamp and active cell
Distance, the pretightning force size of pipe fitting is also can determine from the distance of torsion.
Further set：The centering holder includes two pieces of grip blocks being slidably connected in longitudinal slide rail and for driving
The actuator that dynamic grip block slides towards opposite direction.
Further set：The actuator includes driving leading screw and the leading screw handle for adjusting driving leading screw, drives silk
Thick stick is provided with the screw thread of two sections of opposite directions, and two pieces of grip blocks are connected with by two sections of screw threads with leading screw respectively
By using above-mentioned technical proposal, operating personnel's rotating threaded shaft handle, leading screw handle drives driving leading screw rotation, due to driving
For two sections of hand of spirals on dynamic leading screw on the contrary, when therefore driving leading screw rotation, grip block on two sections of screw threads can be to opposite
Direction is moved, and tightens pipe fitting so as to reach, the purpose of appropriate pretightning force is provided for pipe fitting.
Further set：The horizontal slide rail that direction is set towards pipe casting clamp is fixed with the frame, active cell is set
Put in horizontal slide rail.
By using above-mentioned technical proposal, the setting of horizontal slide rail can facilitate active cell in frame toward and away from
Pipe casting clamp slides, and realizes the assembling of pipe fitting.
In summary, the invention has the advantages that：
The automatic pretension of threaded fitting can be mitigated hand labor intensity.Provided with torsion control system, torsion is avoided to cross havoc
Workpiece, the too small poorly sealed unqualified phenomenon of leakage.Its transverse movement is controllable, avoids passive pipe fitting screw thread part from being completely superposed
Torsion is not up to setting value, and rotary motion is carried out always, destroys workpiece phenomenon.The present disclosure applies equally to the pre- of collar joint
Tightly.
