Background technology
At present, being threaded is the main connected mode of plug, pipeline in metallurgy, petroleum drilling and mining and refinery field, metallurgy industry seamless steel tube production milling train plug; Drilling rod, drilling tool, tubing and casing in petroleum drilling and mining industry; Pipelines in refinery field etc., its main connected mode is for being threaded.On unload connecting thread specific purpose tool be joint hoop screwing machine with effects.
While detaining on connecting thread, must strict control torque wrench moment, only in this way just can make to manage bar carrying, withstand voltage properties, serviceable life and obtain basic assurance.The size of torque wrench moment value directly affects detains quality on screw thread.The too small meeting of torque wrench moment value causes pipe rod seal bad or come off; During thread up, rear thread damage cannot be dismantled or dismantle to the excessive screw thread that can cause again of moment of torsion, can produce strain crack, thereby reduce the intensity of whole pipe bar, the fracture that even produces screw thread place when serious.
Existing multiple special moment of torsion detects and controls pen recorder use on joint hoop screwing machine with effects at present.Whether the measurement that these moments of torsion on joint hoop screwing machine with effects detect control pen recorder accurately directly affects button quality, therefore, need this special torque calibrating device of joint hoop screwing machine with effects torsion calibration device to detect control pen recorder for the moment of torsion of demarcating on joint hoop screwing machine with effects.
Due to joint hoop screwing machine with effects, frequency of utilization is high aborning, working strength is large, make the wearing and tearing of joint hoop screwing machine with effects machine driven system very fast, power transmission efficiency changes, no matter be driven by power or hydraulically powered joint hoop screwing machine with effects, its working current or operating oil pressure are compared and are altered a great deal with the use later stage at the use initial stage with the relation curve between joint hoop screwing machine with effects output torque, and this change procedure is progressive.In view of this joint hoop screwing machine with effects torque calibration of previous reasons should often carry out.
In joint hoop screwing machine with effects structure, mainly comprise main pincers, back-up tong, base, main pincers are rotating mechanism, and back-up tong is fixed mechanism; Main pincers are fixed on base, and back-up tong can slide on base, and the jaw size of the shortest spacing between main pincers and back-up tong, main pincers and back-up tong is different and different with size with the kind of the different of screw-on machine model and the product of need to stubborn practicing midwifery.For the joint hoop screwing machine with effects of different jaw sizes or different model is used a plurality of calibrating installations that involve great expense and is not suitable for, the torsion calibration device that integral structure is connected with flange, because bad adaptability, volume are large, the difficult very inconvenience of dismounting, how joint hoop screwing machine with effects torsion calibration device adapts to jaw size, the different joint hoop screwing machine with effects of main back-up tong spacing, obtain true loading torque value?
Utility model content
The purpose of this utility model is for the problems referred to above, provide a kind of simple for structure, combine flexible, quick and easy for installation, to adapt to different jaw sizes and different model joint hoop screwing machine with effects torsion calibration device, meet the real needs of production scene.
For achieving the above object, the technical scheme that the utility model adopts is: joint hoop screwing machine with effects torsion calibration device, its structure includes the torque sensor main body 1 of both end thread and is positioned at the signaling interface 8 at its middle part, pressure cap 2 is twisted and is connected in the torque sensor main body 1 of both end thread, instrument 10 is plugged on signaling interface 8 by signal cable 9, the torque transmission mechanism 7 that also comprises torque sensor main body 1 two ends that are plugged in both end thread, it is characterized in that: torque transmission mechanism 7 is by torque arm 3, termination 4, end cap 5 and lifting bolt 6 form, one end of torque arm 3 is plugged in the torque sensor main body 1 of both end thread by spline joint, the other end of torque arm 3 is connected with plug-in mounting termination 4 thereon by key, lifting bolt 6 is installed on torque arm 3 through end cap 5.
The utlity model has following advantage: the use of termination in torque transmission mechanism, makes torsion calibration device can pass through to change the different jaw sizes of termination flexible adaptation of different-diameter; The use of torque arm in torque transmission mechanism, make torsion calibration device can adapt to by changing the torque arm of different length the joint hoop screwing machine with effects of the different main back-up tong spacing of different model, torque transmission mechanism be made for one independently functional module greatly improved applicability and dirigibility and the work efficiency of joint hoop screwing machine with effects torsion calibration device.
The utility model is simple for structure, easy to assembly, can effectively adapt to the torque calibration of different jaw sizes and different model joint hoop screwing machine with effects.The impact that the systematic error of torque calibration has comprised power drive system efficiency, makes the moment of torsion showing more approach real torque value.
