Technical field

The utility model belongs to the technical field of circular vibration, in particular to a high-speed circular vibration for stable feeding.

Background technique

The characteristic of the existing I-shaped core gold is that the positions of the fixing bolts of the vibrating plate spring on the vibrating body are on the same line as the positions of the fixing bolts of the piezoelectric element and the fixing body. This is a relatively simple structure. Because the distance between the vibrating body and the fixed body is limited, the amplitude is also limited. In addition, compared with the I-shaped core gold of the existing U-shaped core gold, the actual extra length to the position of the fixed part plays a role in increasing the amplitude. However, because the core metal is fixed on one side, the balance is poor, and twisting movement will occur, making the conveying of the workpiece unstable, and it is also easy to cause noise and abnormal sound. Moreover, the twisting motion phenomenon will offset part of the horizontal thrust, which will affect the high speed to a certain extent. For this reason, we propose a high-speed circular vibration for stable feeding.
