Brief description：
Fig. 1 is this utility model structural representation.
Specific embodiment：
As shown in figure 1, this utility model is a kind of calibrating installation of scene torsion marking apparatus, including lever 1, screw mandrel 2,
Rider 3, stalloy 4, suspension rod 5, pallet 6 and arm lever fulcrum shaft 7,1 one-tenth Y-shaped of lever, the two ends circular sliding slopes of fork,
Torque arm length for ensureing lever is a definite value, one end of lever is designed to 15 degree of circular arc, the thick stalloy 4 of 0.5mm
Upper end be fixed on the top of circular arc by rivet, the lower end of stalloy 4 connects suspension rod 5 and pallet 6, when stalloy is subject to by hanging
After the weight of bar 5, pallet 6 and counterweight, stalloy 4 is tightened up tangent with the circular arc of lever 1, and the length of such arm of force is actually
It is the radius of lever 1 it is ensured that the accuracy of torque arm length.The root end of 1 one-tenth Y-shaped of lever and screw mandrel 2 pass through screw thread 8 even
Connect, rider 3 is contained on screw mandrel 2 and can move about thereon, arm lever fulcrum shaft 7 is serration spline axle, by carrying Triangle ID
The adapter sleeve of shape spline tooth is arranged on the root end of 1 one-tenth Y-shaped of lever and the intersection at fork two ends.
Torque arm length for ensureing simple moment of torsion standard lever is a definite value, and one end of lever is designed to 15 degree by us
Circular arc, and at the top of circular arc, the stalloy of is fixed by rivet, when stalloy is subject to by suspension rod, pallet and counterweight
Weight after, stalloy be tightened up tangent with the circular arc of lever, the length of such arm of force be actually lever radius it is ensured that
The accuracy of torque arm length.
In this utility model, screw mandrel 2 and rider 3 constitute balance regulator.By adjusting on screw mandrel 2 and screw mandrel 2
Rider is balanced tune and connects, and makes to design and is integrated the total length of lever and decreases half, that is, ensure that the accuracy of calibration,
Shorten the length of lever simultaneously, be easy to carrying and suitable onsite application.
For reducing the impact to calibration result for the lever deadweight, on the premise of taking into full account lever rigidity, by lever design
Become hollow structure.
In this utility model, lever arm of force error in length is less than one thousandth, and counterweight force value error is less than 5/10000ths, whole
The error of covering device is less than 3/1000ths.
1 calibration steps and principle
Torsion marking apparatus 9 are fixed on work platformses 11, by triangle internal spline by arm lever fulcrum shaft 7 with set
The dedicated connecting sleeve of meter connects, and the adapter sleeve other end is connected with torsion marking apparatus 9 screw rod (sensor axis), to guarantee arm lever
Fulcrum shaft 7 is reliably connected with by school torsion marking apparatus 9, then lever 1 one termination suspender, and the other end installs balance regulator.
Adjustment device, makes lever be horizontal；The sensor of torsion marking apparatus 9 is connected with its display device 10.According to
Selected torque calibration point, the weight calculating loading counterweight first respectively is standard test weight weight (lever length is definite value),
Secondly, according to selected calibration point, steadily it is incremented by and applies counterweight to standard test weight weight, record torsion marking apparatus display instrument
The mass value (standard test weight value) of indicating value and counterweight, counterweight now is this torsion with the static moment of torsion of the product formation of torque arm length
The standard torque value of square marking apparatus.
2 method validations
With this device, scene torsion marking apparatus each point is calibrated, gained expanded uncertainty (k=2) it is less than or equal to by the 1/3 of school torsion marking apparatus limits of error absolute value, measurement knot
Fruit accurate and effective.U in formula1、U2、U3It is respectively the standard uncertainty of measurement reproducibility introducing, counterweight allowable error introduces
The standard uncertainty that standard uncertainty, simple moment of torsion standard lever allowable error introduce.
