Vibration reduction method and vibration reduction system

Abstract

The invention provides a vibration reduction method of a multifunctional machine. The vibration reduction method of the multifunctional machine includes the steps of providing a balance module movably connected with an output shaft and synchronously swinging together with the output shaft, obtaining parameters of extrusion conducted on a shaft sleeve through the output shaft in at least two staggered directions, judging whether each extrusion parameter belongs to a preset threshold range or not, if yes, continuing to keep synchronous swinging between the balance module and the output shaft, and if not, changing the relative position of the balance module and the output shaft so as to adjust each extrusion parameter to be within the preset threshold range. According to the vibration reduction method, the relative position of the output shaft and the balance module is adjusted by comparing all the extrusion parameters till all the extrusion parameters belong to the preset threshold range, then synchronous swinging of the balance module and the output shaft is kept and the vibration of the multifunctional machine is the smallest at the moment. The invention further provides a vibration reduction system corresponding to the vibration reduction method.

Description

technical field [0001] The invention relates to the technical field of multifunctional machine vibration reduction, in particular to an automatic operation vibration reduction method and a vibration reduction system corresponding to the vibration reduction method. Background technique [0002] The more common multi-function machines currently on the market generally include a motor. The motor shaft of the motor is connected to an eccentric pin, and a bearing is sheathed on the eccentric pin, thereby forming an eccentric wheel structure. When the motor shaft rotates, the eccentric wheel structure can rotate eccentrically around the axis of the motor shaft. The output shaft of the multifunctional machine is set perpendicular to the motor shaft, and a shift fork assembly is fixedly connected to the output shaft. The shift fork assembly has two opposite extension arms, which surround the eccentric wheel structure, and the extension arms of the two extension arms The inner sides...

Problems solved by technology

[0003] However, when the multi-function machine is working, the shift fork, output shaft and working head move together as a swinging whole. Since the shifting fork and working head have a certain mass, the center of mass of the swinging whole is not on the swinging axis of the output shaft, resulting in The overall eccentric swing of the swing will inevitably produce large vibrations, which will always act on the output shaft and the sleeve on the outside of the output shaft, and then be transmitted to the user's hand. In the case of using a multi-function machine, it will produce a large numbness feeling, which is not conducive to the user's use, and is also harmful to the user's hand health
