Description

Technical Field

[0001] The utility model relates to the technical field of mechanical metrology equipment, in particular to a mechanical metrology verification and calibration platform. Background Art

[0002] The mechanical calibration room of the Metrology Institute usually performs calibration and verification on torque wrench calibrators, working dynamometers, tension sensors and other multi-specification and multi-variety torque measuring instruments of equal force values. The existing calibration test bench in the mechanical testing room is a cement platform, which has the following problems in practical application: 1) The platform can only be used to calibrate measuring instruments such as torque wrench calibrators, and the calibration of measuring instruments such as dynamometers and tension sensors can only be carried out manually. Not only will the jitter of manual operation affect the uncertainty of detection, but there is also a safety hazard of weights falling and hitting the calibrators; 2) When calibrating the torque wrench calibrator, the torque wrench calibrator can only be pressed and fixed on the platform using a pressure plate and a screw installed on the pressure plate. For the torque wrench calibrator equipped with a special tooling that can adjust the level of the torque wrench calibrator during calibration, its special tooling cannot be installed. Not only will the level of the cement platform and the platform that is worn after long-term use affect the level of the torque wrench calibrator during calibration, thereby affecting the uncertainty of detection, but the platform can only be installed with torque plate calibrators that meet the appearance dimensions, and the scope of use is narrow and inconvenient.

[0003] For this purpose, an application number: 202220996289.7 appeared. A mechanical metrology verification and calibration test bench can better solve the above-mentioned technical problems. However, when the existing mechanical metrology verification and calibration test bench is conducting verification and calibration of measuring instruments such as dynamometers and tension sensors, when placing a weight plate or a weight hanging table, if the weight plate or the weight hanging table falls, the weight plate or the weight hanging table will directly contact the ground, which may easily cause the weight plate or the weight hanging table to be bumped or damaged, which is not conducive to use.
