Face is provided with the upper ejector pin shaft shoulder, and upper ejector pin is realized by the upper ejector pin shaft shoulder and is connected with device to be calibrated；Adjusting rod cone nest with
The inner ring that the upper ejector pin cone nest is surrounded is in be arranged at the adjusting rod with the matched circle in steel ball outer ring, the steel ball
Between the circular inner ring that cone nest and upper ejector pin cone nest are surrounded.
Preferably, at least two adjusting rod blind hole is evenly equipped with the adjusting rod outer circumference face, the adjusting can be passed through
Bar blind hole rotates the adjusting rod, specifically, when twisting the external thread rod, steel is connected in the adjusting rod blind hole
Rod is convenient to rotate the adjusting rod to increase torque.
Preferably, several base blind holes are evenly equipped with the chassis outer side periphery, prevent base from rotating the tune
The adjusting rod is followed to rotate during pole, specifically, by connecting a steel rod in the base blind hole to increase torque, to prevent
The base is rotated with the adjusting rod.
Preferably, some base plate through holes are circumferentially evenly equipped with the base, to mitigate base weight.
Preferably, the steel ball, adjusting rod cone nest, the equal hardness height of upper ejector pin cone nest, surface are smooth, to reduce
Its rotating friction force.
Compared with prior art, a kind of performance test bed inertia calibration external rotation axis, Neng Goufu provided by the invention
Performance test bed active and passive end is helped to implement inertia calibration, and it is simple in structure, it is easy to use, it is easily operated with realizing, have at the same time
There is relatively low rotating friction force.
Certainly, implement any of the products of the present invention and do not necessarily require achieving all the advantages described above at the same time.
