Description
Technical field
The utility model relates to a kind of pick-up unit for detecting torque spanner torque value, can set the monitoring and testing of the instrument of output torque and the moment of torsion output of equipment for prefabricated dial torque wrench, dial type dial torque wrench, Digital Electronic Torque Wrench and torque multiplier etc.
Background technology
In current commercial unit, a lot of device product, especially Large-Scale Equipment, equipment key components and parts connect all use bolt and nut connected mode so as maintenance in the future, maintenance.Such as: steam power plant, hydro-electric power generating equipment, nuclear power generating equipment, wind power generating set equipment, metallurgical equipment, mining equiment, shipbuilding equipment, auto industry, petrochemical equipment, Aero-Space etc. have thousands of large-sized bolt for the connection of its key components and parts, these bolts all need according to design technology requirement, use can export the Digital Electronic Torque Wrench of amount moment of torsion, dial type dial torque wrench, prefabricated dial torque wrench or torque multiplier are tightened and are dismantled, identical to guarantee that the pretightning force of each coupling bolt is tried one's best, guarantee that equipment component is by effectively, safety, reliable connection.But the torque setting of these torque tools or equipment be all when being dispatched from the factory by producer theory calculate out or by external torque sensor calibrating factory-said value, after China employs a period of time, consider the problems such as cost do not do period spot check or spot check error large, cause the bolted moment of torsion Joint failure of the parts of domestic a lot of key equipment, time serious, blast is leaked in the accident that can cause such as chemical plant, and Leakage of Oil Storage pollutes, aerogenerator collapses, automobile non-driver human accident etc.
The torque tester existed in the world at present, uses an elastomeric elasticity coefficient, then goes out to act on the moment of torsion on elastic body according to corresponding Deformation calculation.After a certain period of use time, due to factors such as fatigue deformations, can there is certain change in elasticity coefficient to such elastic body, so the moment of torsion surveyed is in the different lifetime stage of equipment, measure the moment of torsion come to be not quite similar, need to carry out spot check after a certain period of time, be confirmed whether to need repairing.
The device of existing testing calibration torque spanner, majority is that import equipment quality is pretty good, but cost is high, the arrival time is long, upkeep cost is expensive, and most units scruple Cost Problems is seldom bought.And the device of the testing calibration torque spanner that more domestic producers do, majority is hand gear, wastes time and energy when working; The device of the testing calibration torque spanner that calibration department majority uses, also be all hand gear, can find owing to artificially participating in too much by use, personal error is large, and the general each point of torque spanner (preset) will be twisted minimum three to five times (according to spanner quality) in advance and wasted time and energy, turning excessive velocities can cause error excessive bad with repeatability on the contrary, this is all to bring the additional force such as shock and vibration, moment of flexure, and the reason of these additional reasons on the impact of torque measurement brings error just.
No matter the well-known large enterprises of country facilities are as Samsung, Motorola, Toyota Motor, Great Wall Automobile etc. or the company of some specialize foundries, the place of using torque spanner is too many, originally Here it is by a kind of common tool (opening spanner, ratchet spanner etc.) develop, it is also natural for can not get paying attention to, but they have in the face of a problem, cross various examination & verification, have on the one hand from buying side, have on the one hand from national Related product quality testing department, this all does to supervise product whether qualified, such examination & verification is all generally circulation, annually or for many years once, and the vertification regulation regulation calibration interval are 1 year.Among this year, few people frequently and can spend an expense to go to metrological service to verify because use again, this just constitutes some above-mentioned hidden danger, remove a hidden danger and just relate to outer inspection or buy standard set-up voluntarily, the test of the actual torque of its torque tool or equipment and be aligned in producer and do not have a kind of reliable and stable, be simple and easy to use, economical and practical torsion-testing instrument.
In a word, whether the factory-said value of the torque tool equipment bought correctly cannot be verified, after torque tool equipment use certain hour, whether the torque value of setting or the torque spanner of a upper annual test still correctly cannot be determined, in calibration cycle, frequency of usage is excessive, the error that user of service's misoperation is brought not easily is determined, these of having become industrial trade bolt assembly working are difficult to the bottleneck broken through.
