In industrial production, the six axis reciprocating machine is an important automation equipment, and the wear of each axis after long-term continuous operation directly affects its performance and service life. Effective monitoring and evaluation are crucial.

1、 Monitoring methods

Sensor monitoring: Displacement sensors, pressure sensors, etc. can be installed at key locations. The displacement sensor can monitor the position changes of the shaft in real time. If the shaft wears out, its running trajectory will change, and the displacement sensor can capture these subtle changes. Pressure sensors can monitor the pressure that the shaft is subjected to during operation, and wear may cause uneven pressure distribution. The sensor can provide timely feedback.

Oil analysis: By regularly collecting lubricating oil samples from a six axis reciprocating machine, analyze the content and composition of metal particles in the oil. Different shafts are made of different materials, and the metal particles generated by wear will blend into the oil. Through spectral analysis, iron spectrum analysis, and other methods, the worn shaft and degree of wear can be determined.

Vibration monitoring: Use vibration sensors to monitor the vibration of the shaft during operation. When the shaft is operating normally, the vibration amplitude and frequency are within a certain range. Once wear occurs, the vibration characteristics will change, such as an increase in vibration amplitude and abnormal frequency. By analyzing these changes, the wear condition of the shaft can be determined.

2、 Evaluation indicators

Wear amount: directly measure the dimensional changes of the shaft and calculate the wear amount. By comparing with the initial dimensions, the degree of wear of the shaft can be intuitively understood. The greater the amount of wear, the more severe the wear on the shaft.

Surface roughness: Use a surface roughness measuring instrument to measure the surface roughness of the shaft. Wear and tear can make the shaft surface rough, increase surface roughness, and affect the operational accuracy and stability of the equipment.

Gap variation: The fit gap between the shaft and other components may change due to wear. By measuring the gap size and comparing it with the standard value, determine the impact of wear on equipment operation. Excessive clearance may lead to increased equipment vibration, noise, and even affect the normal operation of the equipment.

By comprehensively applying the above monitoring methods and evaluation indicators, it is possible to comprehensively and accurately grasp the wear and tear of each axis of the six axis reciprocating machine after long-term continuous operation, provide scientific basis for equipment maintenance and upkeep, ensure stable operation of equipment, extend equipment service life, and reduce production and operation costs of enterprises.
