Description

Sucking disc device capable of continuously rotating

Technical Field

The utility model belongs to the technical field of suction disc device, especially, relate to a suction disc device that can rotate in succession.

Background

The Bernoulli sucker is commonly used in a workpiece sucking device and used for sucking a sheet-shaped workpiece, when the sucker is connected with compressed air by applying the Bernoulli principle, the working surface of the sucker generates uniform and thin strong airflow, the gas flow velocity of the upper surface of the workpiece is greater than that of the lower surface of the workpiece, the pressure difference can be generated on the upper side and the lower side of the workpiece by utilizing the principle that the fluid velocity is faster and the pressure is smaller, so that upward lifting force can be formed at the bottom of the workpiece, and the workpiece is sucked on the lower surface of the sucker body.

In the actual use, often need rotate the work piece of absorption, current sucking disc can not direct rotation, in order to realize the purpose of rotatory work piece, needs to increase other parts such as gas-liquid sliding ring for the structure of sucking disc is complicated, leads to with high costs, easily takes place to damage the scheduling problem.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a low-cost, easily realize 360 continuous rotation's bernoulli sucking disc device, be applicable to the occasion that turns to in succession the work piece, solve the problem that above-mentioned sucking disc exists.

The utility model discloses a realize through following technical scheme:

a continuously rotatable sucker device comprises a sucker core, a sucker body, a sucker housing, a rotary air pipe joint, a hollow shaft and a hollow shaft motor;

the sucker core is arranged in the sucker body, the sucker housing is arranged outside the sucker body, a disc is arranged below the hollow shaft, and the disc of the hollow shaft and the sucker housing are connected into a whole through screws.

The upper end of the sucker core is connected with the lower end of the rotary air pipe joint through threads, and the other end of the rotary air pipe joint is a compressed air quick-connection joint.

The compressed air quick connector is a through connector capable of rotating quickly, and when the sucker rotates, the compressed air pipe and the connector can be sealed, and compressed air cannot be leaked.

The hollow shaft is connected with the hollow shaft motor through threads, and the hollow shaft motor can be a stepping motor or a servo motor as a power source for rotation of the sucker.

The bottom surface of the sucking disc also comprises an inner ring gasket and an outer ring gasket, so that the effect of isolating the workpiece is achieved, the contact between the sucking disc and the workpiece can be reduced, and the precision workpiece is not easily damaged.

Compressed air passes through the hollow shaft of hollow shaft motor and the rotatory air pipe head who fixes on the sucking disc core gets into in the sucking disc, when the needs sucking disc is rotatory, the motor drives when the sucking disc is rotatory, drives rotatory air pipe head is rotatory, and the irrotational of compressed air trachea to realize 360 rotations of sucking disc.

The utility model discloses following beneficial effect has:

1. the 360-degree continuous rotation of the sucker can be realized.

2. The in-line rotary air pipe joint is adopted to access compressed air, so that the use of complex parts is avoided, and a low-cost sucker rotating scheme is provided.

3. The structure is simple, thereby improving the reliability of the system and being capable of being maintained quickly and conveniently when a fault occurs.
