Problems solved by technology

However, with the increase of production batches, the workload of manual gear grinding is very large, and the running-in standards are not uniform, which is not conducive to the expansion of production scale and the improvement of product consistency.
In addition, when the servo mechanism is reworked and ground, it will inevitably cause certain wear and tear on the installed servo motor, tachometer, potentiometer and other rotating components, which reduces the reliability of the servo control system
In addition, when the teeth are manually ground, the servo mechanism swings back and forth to form a certain impact on the mechanical limit position, which also causes considerable damage to the gyroscope.
[0006] It can be seen that using the current technology to test the stability of the servo control system, there are disadvantages and technical limitations such as damage to the secondary accessories, poor implementability, and delay in the failure cycle.
[0007] Further, in the prior art, the running stability of the servo mechanism is tested, and electrical components can also be used for feedback control, but this method needs to modify the existing servo control system, and the existing disadvantages are that the servo control system is complicated, expensive, and unfavorable. accomplish

Abstract

The invention relates to a method for quantitatively controlling the operational stability of a servo mechanism by using an automatic gear grinding technology. The method can be implemented through adopting an automatic running-in and stability test system. The method includes the steps of movement control, data collection and analysis, and running-in parameter and evaluation criterion establishment. According to the movement control, the servo mechanism moves in a reciprocating manner in an operation position range under control according to movement parameters and operation positions, and automatic gear running-in is performed on the transmission chain of the servo mechanism. According to the data collection and analysis, in an automatic gear running-in process, work state parameter data are acquired, and are processed, and processing results are display in real time. According to the running-in parameter and evaluation criterion establishment, operational stability quantitative detection is performed on the servo mechanism, and the running-in process parameters of the transmission chain of the servo mechanism are determined, and quantitative evaluation criteria of qualified running-in are established. With the method of the invention adopted, automatic running-in of the transmission chain of the servo mechanism can be completed with shortest time and minimum manpower and material resources, and the stability detection of the servo mechanism can be realized with quantitative evaluation indexes, and malfunctioned products can be reduced, and the rate of rework in processes can be reduced, and batch production efficiency and product reliability can be improved.
