Technical Field

[0001] The utility model belongs to the technical field of detection and calibration testing machines, and particularly relates to a multi-component sensor detection and calibration testing machine. Background Art

[0002] At present, multi-component sensors can simultaneously detect multi-directional mechanical information in three-dimensional space and have been widely used in product testing, automated industrial production lines, robots, and machine grinding and polishing control systems. For example, multi-force detection of wheels, robotic surgery, wind tunnels, experimental studies on various hydrodynamic problems of aircraft and ships in water tanks, and neurological research. In the existing technology, there is no dedicated device for the detection and calibration of multi-component sensors.

[0003] Existing testing machines generally use a hydraulic cylinder to load a multi-component sensor, and can only achieve tension and compression in one or two directions. To achieve multi-directional loading, separate tests need to be carried out on different testing machines, and simultaneous loading and force application in multiple directions cannot be achieved, so the comprehensive performance of multi-component sensors cannot be tested. Summary of the Utility Model

[0004] Aiming at the above deficiencies, the utility model provides a multi-component sensor detection and calibration testing machine, which uses multiple oil cylinders to apply forces simultaneously in multiple directions to detect the comprehensive performance of multi-component sensors, and has the advantages of convenient use, high control accuracy, and good reliability.
