Description

Circular vibration type conveying device

Technical field

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 circular vibration conveying device.

The piezoelectric element 5 is fixed on both sides of the vibration source. The carbon fiber vibration plate spring 4 does not produce twisting motion when vibrating. Therefore, the high speed is easier to achieve, and the high speed can be achieved. For stable feeding, one end of the piezoelectric element 5 is fixedly connected with a carbon fiber vibration plate spring 4, and one end of the core metal 3 is fixedly connected with a vibrating body connection part 6.

As shown in Figures 6 to 8, the carbon fiber vibration plate spring 4 is fixed on the back side of the core metal 3 in the direction of rotation. The horizontal arrangement direction C of the core metal and the carbon fiber vibration plate spring and the core metal motion track form a circle tangent D. At an angle of 90 degrees, the vibration direction of the core gold 3 is tangent to the circle formed by the movement track of the core gold 3, that is, the carbon fiber vibration plate spring 4 is installed on the rear side of the piezoelectric element 5 and fixed by bolts. The angle between the plane B where the core gold 3 is located and the plane where the circle A formed by the movement trajectory of the core gold 3 is located is less than 90 degrees. This installation method is for the rotation direction. When the vibrating plate spring is arranged behind the piezoelectric element, the vibration direction is The direction of rotation is relatively outward. As shown in FIG. 8, when the vibration plate spring is arranged in front of the piezoelectric element in the direction of rotation, the direction of vibration faces the inside of the direction of rotation, as shown in FIG. 7.
