Description
Technical field
The utility model belongs to be measured and mechanical engineering technical field, especially relates to a kind of torque transmission device of the gamut moment of torsion calibrating instrument that automaticallyes switch.
Background technology
Thread connection has the advantages that to repeat dismounting because of it, and more and more is subjected to the widespread use of every profession and trade, as manufacturings such as aircraft, automobile and precision equipments.Accordingly, manpower that drops in the screw thread tightening operation and expense are also increasing, meanwhile, the double thread tightening operation has also proposed certain requirement, especially for some important thread connection operations, not only require high efficiency, and the quality of work such as the accuracy of screwing force and moment of torsion are also had requirement.In assembling process, if moment of torsion is excessive, seriously surpass the yield limit of thread connector material, will make the screw thread fracture failure of thread connector, fastening failure; If moment of torsion is too small, do not reach the effect of fastening clamping, also can cause fastening failure.Connection for important spare part is then particularly important, as the securing member of doughnut, the securing member on the cable car support, the securing member on the space shuttle launcher spademan support etc., can not be up to standard as the accuracy that connects, and consequence is comparatively serious.Therefore, for guaranteeing the quality of tightening of securing member, be extensive use of dial torque wrench in the fastening process of each engineering goods, to guarantee the screw-down torque of each securing member.
Dial torque wrench is the important measurement instrument of control product quality, and its manufacture view at Aeronautics and Astronautics, boats and ships, automobile, petrochemical industry, precision optical machinery and exact instrument etc. is widely used.For guaranteeing the accuracy of dial torque wrench, each manufacturing enterprise need deliver the dial torque wrench of producing through the measurement unit or the metrological service of authorized by state and examine and determine or calibrate, and respectively use enterprise to need regularly dial torque wrench to be delivered through the measurement unit or the metrological service of authorized by state to examine and determine or calibrate, and the specialized equipment that calibrating or calibration dial torque wrench use is torque wrench system or calibrating instrument.
At present, domestic and international widely used torque wrench instrument is to utilize single-sensor to carry out limited moment of torsion calibrating in its linearity measuring range scope.
As shown in the table is the sensing range of the torque wrench instrument of single measuring head (single-sensor):
| Model | Calibrating scope (unit: N.m) | Scale division value (unit: N.m) |
| TC-2 | 0.4～2 | 0.0005 |
| TC-5 | 1～5 | 0.001 |
| TC-10 | 2～10 | 0.002 |
| TC-20 | 4～20 | 0.005 |
| TC-50 | 10～50 | 0.01 |
| TC-100 | 20～100 | 0.02 |
| TC-200 | 40～200 | 0.05 |
| TC-300 | 60～300 | 0.1 |
| TC-500 | 100～500 | 0.1 |
| TC-1000 | 200～1000 | 0.2 |
| TC-2000 | 400～2000 | 0.5 |
