Suction disc provided with bidirectional edge

Abstract

The invention discloses a suction disc provided with a bidirectional edge and belongs to the technical field of vacuum adsorption. According to the suction disc, a connecting piece is a hollow cylinder, a thread is arranged on the outer ring of the upper portion of the cylinder, a suction disc assembly is formed by connecting an upper boss and a lower suction disc body smoothly, the boss is a hollow cylinder, and a groove is formed in the inner ring of the hollow cylinder of the boss. The suction disc body is in a hollow semi-cone shape, and an included angle alpha formed between an inclined surface of the suction disc body and the horizontal plane is 30-60 degrees; a suction ring is arranged on the inner wall at the lower end of the suction disc body and is in an inverted hollow semi-coneshape, and an included angle alpha formed between the suction ring and the lower end of the suction disc body is 60-120 degrees; and a flange at the outer ring of the lower portion of the connectingpiece is matched and fixedly connected with the groove in the boss in the suction disc assembly. According to the suction disc, through the bidirectional edge design of the suction ring and the lowerend of the suction disc body, either of the lower end edge, extending outwards, of the suction disc body and a circular ring which is in an inverted cone shape and extends inwards makes tighter contact with a contacting surface when the suction disc body bears bending moment generated by yawing force, and accordingly, the better sealing performance of the suction disc is guaranteed.

Description

Technical field [0001] The invention belongs to the technical field of vacuum adsorption, and specifically relates to a suction cup with a bidirectional edge. Background technique [0002] With the continuous upgrading of industrial automation, the application of robotic arms that can realize the handling function is becoming more and more extensive. Suckers are widely used in industrial manipulators and life hooks due to their unique adsorption characteristics. In the industry, the suction cup as a suction hand is often connected to a vacuum pump through a gas pipe, and the inside of the suction cup is vacuumed through the action of the vacuum pump. Due to the pressure difference between the inside and outside, the suction cup and the contact are tightly adsorbed together. In daily life, the suction cup is often used as a suction hook. When the suction cup is used as a suction hook, due to the simple structure and low cost, the hook suction cup is generally not connected to th...

AI Technical Summary

Problems solved by technology

The side of the suction cup opposite to the direction of the lateral force tends to be lifted, so that the gas can easily enter the interior of the suction cup from this side, making the suction cup lose its adsorption capacity. Therefore, it is necessary to invent a suction cup that can effectively resist the lateral force and firmly absorb
