Standard torque wrench calibration device based on deadweight torque standard machine and method thereof

Abstract

The invention provides a standard torque wrench calibration device based on a deadweight torque standard machine and a method thereof. The device comprises the deadweight torque standard machine, an external guiderail, a calibration unit and a liquid static pressure bearing. According to the standard torque wrench calibration device, a torque applying component and a torque bearing component on the deadweight torque standard machine move on the inner guiderail of the calibrating unit, and only a fan-shaped support moves on the external guiderail. Furthermore the movement of the fan-shaped support is not restricted by any component on the inner guiderail. The external guiderail settles a position adjustment problem of a calibrating unit and furthermore can move to the leftmost side of the body when only an original torque standard machine function is used, thereby realizing no influence to the original function of the torque machine. Furthermore, the liquid static pressure bearing is utilized for reducing influences of various adverse component forces to a standard torque to a lowest limit, wherein the liquid static pressure bearing is a current best solution.

Description

technical field [0001] The invention relates to a verification device, in particular to a standard torque wrench verification device based on a static weight torque standard machine. Background technique [0002] The verification of working torque wrenches generally uses a torque wrench calibrator, and the verification of a torque wrench calibrator mostly uses a standard torque wrench, while the verification of a standard torque wrench requires a standard torque wrench calibrating device. [0003] At present, there is no standard device in the market that conforms to the verification equipment of JJG1103-2014 "Standard Torque Wrench". The influence of this kind of bad component force on the torque indication value makes it difficult to guarantee the accuracy of the calibration device and the detection efficiency is low. Contents of the invention [0004] The object of the present invention is to provide a standard torque wrench verification device and method based on a de...
