Multi-functional torque calibration device

Abstract

The invention provides a multi-functional torque calibration device and belongs to the field of measurement and detection, torque detection and calibration, and torque testing. The device comprises a basis foundation (10) and a triangular support structure; the triangular support structure comprises a first group of vertical shafts (9), a second group of vertical shafts (3) and a third group of vertical shafts (2). The multi-functional torque calibration device integrates the detection and calibration functions of a hydraulic torque wrench, a torque multiplicator, a torque sensor, and a torductor and realizes wide-range-section, and high-precision multifunctional torque calibration and the source tracing of a standard torque wrench. The multi-functional torque calibration device has the function of a 1,000 Nm high-accuracy reference standard torquer, and can be expanded into 30 kNm reference large-torque calibration device when matched with a special tool.

Description

technical field

[0001] The invention belongs to the fields of measurement detection, torque detection calibration, and torque testing, and in particular relates to a multifunctional torque calibration device, which is used for detection and calibration of torque tools such as hydraulic torque wrench, torque multiplier, torque sensor, torque measuring instrument, and standard torque wrench . Background technique

[0002] At present, there are some hydraulic torque wrench detectors and torque multiplier detectors with independent functions in China, but they have problems such as simple structure, narrow range, poor flexibility, and unscientific detection methods. The specific analysis is as follows:

[0003] At present, most of the torque multiplier detection chambers are input through a prefabricated manual torque wrench, and the output end is a torque sensor to measure the output torque. At this time, the input torque has an error in the input itself due to the error of th...
