Description

Technical Field

[0001] The utility model belongs to the technical field of measuring instrument verification and calibration, and in particular relates to a verification device for quality detection of a torque verification instrument. Background Art

[0002] A torque wrench tester is an intelligent, multifunctional measuring instrument designed and manufactured for testing and inspecting various torque wrenches. It is primarily used to inspect and calibrate various torque wrenches, including tightening force testing and destructive torsion testing of parts. my country's metrological verification regulations for torque wrench testers eliminate the use of a torque standard machine for verification, retaining the verification lever and force weight method. Therefore, most torque wrench testers use this method as the metrological standard for verification and calibration.

[0003] Chinese patent CN213779373U discloses a calibration device for a torque wrench calibrator, which belongs to the technical field of measuring instrument calibration. The calibration device for a torque wrench calibrator includes a combined bracket, a reference platform is provided on the upper portion of the combined bracket, a lever support seat and a leveling mechanism are provided on the reference platform, a calibration lever and multiple position sensors for detecting the position status of the calibration lever are provided on the lever support seat, scale hooks for placing force weights are symmetrically provided at both ends of the calibration lever, and a lever limiting mechanism is provided below the calibration lever.

[0004] In the existing calibration lever and force weight method, the torque wrench calibrator calibration device does not have a leveling mechanism. After the weight load is applied to the hook tray of the calibration lever, the calibration lever will rotate downward along the center of the sensor in the direction of loading, causing the calibration lever to deviate from the horizontal position, resulting in the vertical distance from the center of the sensor to the load direction, that is, the effective force arm, to change, thereby affecting the accuracy of the calibration result. In the above document, a leveling mechanism is designed to automatically level the calibration lever when loading is applied to ensure the vertical distance from the center of the torque sensor to the load direction. However, the hook is hung in the opening on the lever arm. When the hook is removed for adjustment, the open weight on the hook is easy to fall off, which is inconvenient to use.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content
