Description
Technical field
The utility model belongs to the torque measurement technical field, is specifically related to be directly installed on carry out the device that moment of torsion is measured fast on the workpiece for measurement.
Background technology
Torque measurement be the development research, test analysis, quality inspection, pattern of various engineering goods identify and work such as energy-conservation, safety and optimal control in requisite content.By the moment of torsion of measurement mechanical equipment, can the analyze and research force-bearing situation of part, mechanism and the mechanism of some physical phenomenon.Therefore, torque measurement and analysis are the important means that the energy, raising system effectiveness were normally moved, saved to various productions of assurance and utility appliance safety.Along with progress of science and technology and development of productivity, the torque measurement technology has obtained using widely in many-sides such as motor, automobile, boats and ships transportation, traffic, diesel engine, chemical machinery, oil, metallurgy.
Especially in the process that loading spectrum is gathered, measuring torque signal is its groundwork, and will carry out the torque signal collecting work of multiple industrial and mineral, type, and collection period is long, the cost costliness.
Advantages such as in the prior art, the detection means of torque measurement comparative maturity is a strain measurement technology, and it has, and precision height, frequency response are fast, good reliability and life-span are long.The survey twisting strain sheet of special use is sticked on the tested elastic shaft with strain gage adhesive, and form strain bridge,, can test the electric signal that this elastic shaft is turned round if provide working power to strain bridge.Basic torque sensor pattern that Here it is.Yet, in order to guarantee the installation requirement of sensor, to carry out careful polishing, cleaning to tested elastic shaft test position before the paster, carry out processing such as the fixing and moistureproof and waterproof of the bonding of sensor during paster with AB glue, insulating tape etc., this just must pull down axle to be measured it is handled when measuring moment of torsion, thereby prolonged the test duration, and complete machine has also been had a negative impact.In addition, no matter the signal transmission is to adopt slip ring or employing wireless transmission to strain gauge transducer, all has weak point: for adopting the slip ring mode, can be subjected to the influence that contact resistance changes; For adopting wireless transmission, because of emitting antenna or coil rotate with axle, the signal intensity that can cause receiving trap to receive changes, sometimes even can loss signal.
In addition from present domestic and international technical merit, although the telemetry system that transmission precision is higher, antijamming capability is strong is much, but because the power supply and the emitting module of rotational telemetry system must be contained in the rotating shaft, need look the tested object difference during actual the use and do special design, so the complete property of system is a more scabrous problem.
Therefore, a kind of moment of torsion that can carry out of utility model is measured fast, and has the torque-measuring apparatus of the broad scope of application, has become the active demand of the work such as development research, test analysis and quality inspection of various engineering goods.
Summary of the invention
The purpose of this utility model is to provide a kind of can being directly installed on to carry out the device that moment of torsion is measured fast on the workpiece for measurement.In addition, but this moment of torsion rapid measurement device can be by changing renewal of facing renewal, the axle and the multidiameter of various outer diameter carried out the quick measurement of moment of torsion, and then improve the scope of application of this device.
But but the utility model form by renewal of facing renewal A2, anchor clamps A3, bolt 4 renewal of facing renewal B5, anchor clamps B6, data collecting instrument 7, signal receiving device 8, strain bridge circuit 9 and sender unit 10,
Wherein anchor clamps A3 and anchor clamps B6 are affixed through bolt 4; Strain bridge circuit 9 and sender unit 10 are fixed in anchor clamps B6 outside surface, and strain bridge circuit 9 is connected with sender unit 10 through transmission line, and sender unit 10 is connected with data collecting instrument 7 through signal receiving device 8; But but renewal of facing renewal A2 and renewal of facing renewal B5 are two respectively, place between anchor clamps A3, anchor clamps B6 and the axle 1 to be measured.
But but renewal of facing renewal A2 and renewal of facing renewal B5 external diameter and anchor clamps A3 and anchor clamps B6 coupling, but but renewal of facing renewal A2 and renewal of facing renewal B5 internal diameter and axle to be measured 1 coupling; But but renewal of facing renewal A2 and renewal of facing renewal B5 inside surface are zigzag, so that closely be connected with the external diameter of axle 1 to be measured, make moment of torsion carry out the free of losses transmission, improve the accuracy of torque measurement.
But but renewal of facing renewal A2 and renewal of facing renewal B5 are the fan-shaped lobe of central angle less than 180 degree, can be convenient to installation and removal.
When carrying out torque measurement, device of the present utility model directly can be installed on the axle 1 to be measured, thus the quick measurement of realization moment of torsion.
In addition, but because but the internal diameter of renewal of facing renewal A2 and renewal of facing renewal B5 can be changed at any time according to axle 1 external diameter to be measured, therefore can measure the moment of torsion of different-diameter axle to be measured and multidiameter easily, greatly improved the scope of application of the present utility model.
The course of work of the present utility model is as follows:
At first strain bridge circuit 9 is pasted on anchor clamps B6 outside surface.
Then but but renewal of facing renewal A2 and renewal of facing renewal B5 are placed to be measured 1 position to be measured, again that anchor clamps A3 and anchor clamps B6 is fixing with bolt 4, but but simultaneously renewal of facing renewal A2 and renewal of facing renewal B5 are clamped.Will guarantee that bolt 4 has the enough big power that screws this moment, with the calibration strain of assurance strain bridge circuit 9 and the linearity of torque, and the accuracy of sensor electrical output quantity and mechanical input quantity relation.
Next, sender unit 10 and signal receiving device 8 are installed, and data collecting instrument 7.
At last, make axle 1 operate as normal to be measured, utilize the linearity of reading and strain and torque, and the relation of sensor electrical output quantity and mechanical input quantity, calculate axle 1 suffered torque to be measured.
Good effect of the present utility model is: can carry out torque measurement fast, but and can be by changing renewal of facing renewal, the axle and the multidiameter of various outer diameter carried out the quick measurement of moment of torsion, and with low cost, easy operating.
