Abstract
The invention discloses an adaptive block arm mechanism for a torque wrench calibrator. The mechanism comprises a fixed flat guide rail, a bottom slider with a locking mechanism, block rods, a lifting positioning platform, and axial bearings respectively with a rubber outer ring. The double-block-rod structure of the mechanism meets the requirement of verification and calibration of a two-way torque wrench. The axial bearings mounted on the block rods can automatically adjust the force bearing position of a torque wrench to be at a vertical height during checking of initial force so as to find the optimal force bearing height, and the deformation (jointly influenced by the torque wrench and the calibrator) displacement of the force bearing position in the horizontal and vertical directions is compensated timely in the force bearing process to eliminate the friction effect. The block arm mechanism of the invention can accurately apply a force to the force bearing position of the tail of a torque wrench, avoid the influence of adverse component forces generated in the process of calibration to a torque standard instrument and the torque wrench as much as possible, and improve the scientific nature and accuracy of torque wrench indicating value calibration.
