AI Technical Summary

Benefits of technology

This new technology allows for accurate measurements on both pneuled tools (pneumatically driven), electrically charged tools like motors, and other devices without relying solely upon physical contact between them during testing. It uses an elastic disk called a damper instead of traditional springs to achieve similar simulation capabilities while also collecting real work force from multiple functions tests performed simultaneously. Additionally, there are several technical features mentioned beforehand such as ensuring stable operation even if some sources have issues affecting their performance. Overall, these improvements improve efficiency and reliance over existing methods.

Problems solved by technology

The technical issue addressed in these documents relates to current methods for testing pneuumatic or electronic torque tools without providing any dedicated devices specifically designed for their use.

Embodiment Construction

[0016] see figure 1 , Pneumatic / electric torque wrench dynamic verification device is composed of loading power source, flexible buffer, strain-type torque sensor and measurement output system. The loading power source is composed of a scroll air compressor 14, an air tank 13, an oil-water purifier 11, a compressed air filter 10, a precision pressure gauge 9 and a stabilized power supply 5. Among them, the scroll air compressor 14, the air storage tank 13, the oil-water purifier 11 and the compressed air filter 10 are connected in sequence by the air pipe to form a whole, the precision pressure gauge 9 is installed on the pipeline, the condenser 12 is located behind the air storage tank 13, and the built-in Condensate through which the air pipes pass. The tested torque wrench (pneumatic) 8 is connected to the end of the pipeline. If the electric torque wrench is to be measured, the gas tank 13 regulated power supply is directly connected to the tested electric torque wrench. ...

Abstract

The invention is related to the device of pneumatic/electric torque spanner dynamic test, consisting of turbinated air compressor, gas tank, oil-water purifier, air compressed percolator, exact pressure gauge, increase the power source consisting of a few voltage-stabilized source, high accuracy pressure air source or accuracy voltage-stabilized source or electro motion torque spanner, examined torque spanner communicates with strain torque sense organ through flexible buffer, the output system of measuring consists of dynamic strain gauge, data gathering and computer. Measuring the work torque of the examined torque spanner stimulates actual condition through flexible buffer. Buffer consists essentially of dishing spring. The device can stimulate actual condition of pneumatic/electro motion torque spanner, and gathers actual work torque at high-speed through multifunctional test instrument, realizing the torque of dynamic measuring, realizing the dynamic test of pneumatic/electro motion torque spanner.
