Shock absorber tension and pressure measuring instrument and detection method thereof

Abstract

The invention provides a shock absorber tension and pressure measuring instrument and a detection method thereof, which overcome the defects that existing measuring equipment measures data incompletely, and is low in measurement precision and free of a function of perfecting parameter statistics and analysis. The shock absorber tension and pressure measuring instrument comprises a supporting frame, wherein the supporting frame is provided with an operation desk; a motor is arranged below the operation desk; the output shaft of the motor vertically penetrates through the operation desk and is connected with a transmission component in a driving way; the outer end of the transmission component is movably connected onto a sliding component; a tension and pressure detection position is arranged on the sliding component; a tension and pressure sensor is positioned on the tail end of the tension and pressure detection position; the tension and pressure sensor is connected with an amplifier filter, an A/D (Analog/Digital) converter, a microprocessor and an upper computer in sequence; and the microprocessor controls and is connected with the motor through a driving circuit. The detection method of the shock absorber tension and pressure measuring instrument comprises the steps of pressure collection, conversion, judging, storage, transmission, motor control and the like. The shock absorber tension and pressure measuring instrument and the detection method thereof have the advantages of being simple in structure of the instrument, reliable to act, rational in detection program design and clear in detection parameters, thereby being beneficial to further research and analysis.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a detection for the performance of a shock absorber of a washing machine, in particular to a tension pressure measuring instrument for a shock absorber and a detection method thereof. Background technique [0002] The damping shock absorber in the drum washing machine plays a role in supporting the water tub of the washing machine and absorbing the vibration of the water tub. Its quality directly affects the vibration intensity, noise and service life of the washing machine. Therefore it is particularly important to design an instrument for detecting the quality of the shock absorber of the washing machine. [0003] The shock absorber measurement equipment in the prior art usually has defects such as incomplete measurement data, low measurement accuracy, the function of perfect parameter statistical analysis, and lack of technical support for background system processing.
