The driving angle is adjusted by the thickness of the angle adjustment block 203 to achieve the conveying speed adjustment of the return side workpiece. The upper leaf spring 202, the angle adjustment block 203 and the lower leaf spring 204 form a driving source, which is perpendicular to the return groove 201, making the workpiece easier to process and achieving the effect of cost saving.

This structure lowers the center of gravity of the entire feeding equipment, achieves a shockproof effect, and makes the feeding more stable.

The working principle of this invention: under the drive of a common direct vibration mechanism, the vibrating components of the supply slot 101 of the supply assembly and the return slot 201 of the return assembly 2 are on the same direct vibration mechanism, and the transport adjustment is easy and does not require a vibrating transport device with a special shape or structure.

The high-speed direct vibration body drive block is equipped with a leaf spring with adjustable drive angle and a drive block (return side counterweight) to form an integrated structure, which can easily realize the high-speed and stable conveying function of various small workpieces.

This invention has two amplifying leaf springs, leaf springs with piezoelectric elements, two Z-shaped fixing blocks, and two vibration-proof leaf springs. The upper ends of the two pairs of amplifying leaf springs are fixed to the front and rear sides of the supply slot, and the lower ends of the amplifying leaf springs are fixed to a leaf spring with piezoelectric elements, and the lower ends of the leaf springs with piezoelectric elements are fixed to a Z-shaped fixing block, and the upper ends of the Z-shaped fixing blocks are fixed to the top of a vibration-proof leaf spring. The bottoms of the two vibration-proof leaf springs are fixed to the front and rear sides of the bottom plate, and the counterweight is set in the space surrounded by the supply slot, the amplifying leaf spring, the leaf spring with piezoelectric elements, the Z-shaped fixing block, the vibration-proof leaf spring and the bottom plate. The counterweight that maintains balance is fixed to the leaf spring with piezoelectric elements and the Z-shaped fixing block, and the counterweight does not contact the top and bottom.

This invention adds a Z-shaped fixing block to connect and fix the leaf spring equipped with piezoelectric elements and the anti-vibration leaf spring respectively, thereby reducing the height of the entire device while keeping the height of the anti-vibration leaf spring unchanged, thereby saving space and increasing the anti-vibration effect, achieving high-speed and stable feeding.

This invention can save space, the height of the entire structure is low, and it is easier to coordinate with other circular vibration adjustments; the low center of gravity design realizes the stabilization of high-speed transportation. That is, if the center of gravity of the structure is higher, the leaf spring equipped with piezoelectric elements and the vibration of the track will be more likely to be out of sync, and the transportation state will be more likely to be unstable.

This invention can improve the vibration-proof effect, reduce the vibration interference to the peripheral equipment, and reduce the noise to the peripheral devices.

This invention increases the longitudinal length of the anti-vibration leaf spring. In addition to the anti-vibration effect achieved by increasing the length of the anti-vibration leaf spring, it also increases the conveying speed by increasing the amplitude of the forward and backward vibration.

This invention uses a Z-shaped fixing block, which superimposes the amplitude of the anti-vibration leaf spring on the amplitude of the vibrating leaf spring, forming the vibration of the entire vibration machine, increasing the length of the anti-vibration leaf spring and reducing the overall height, increasing the amplitude while reducing noise.

The above is only the best implementation example of this creation and is not intended to limit this creation. Any modifications, equivalent replacements and improvements made within the spirit and principles of this creation should be included in the protection scope of this creation.
