A kind of material taking device of sealing ring

Abstract

A sealing ring fetching device comprises a fetching station and a fetching assembly. The fetching station is provided with a positioning groove, and the internal diameter of the positioning groove is larger than the external diameter of a sealing ring. A limiting structure for limiting falling of the sealing ring is arranged in the positioning groove. The fetching assembly is located over the positioning groove, and comprises a cylindrical portion. The bottom end of the cylindrical portion is in a conical shape, and the external diameter of the cylindrical portion is larger than the internal diameter of the sealing ring. According to the sealing ring fetching device, the sealing ring is grabbed by being held with tension, and through flexibility of the sealing ring, the lower half portion of the fetching assembly grabs the sealing ring. Meanwhile, the sealing ring fetching device carries out precise positioning on the sealing ring through combination of rough positioning and guidance. By means of the sealing ring fetching device, the conflict requirements of fetching and assembly for the fetching assembly structure are met, the problem that flexible sealing rings are difficult to position is solved, and stable and reliable grabbing is achieved.

Description

technical field [0001] The invention relates to the technical field of product installation, in particular to the installation of sealing rings. Background technique [0002] To install the sealing ring on the product, the sealing ring needs to be grasped first. When grasping the sealing ring, there are the following difficulties: [0003] First, the sealing ring is made of rubber material, which is soft and easy to deform, and it is difficult to maintain the original circular shape when clamping. Therefore, it is not suitable to grasp the sealing ring by clamping; [0004] Second, the sealing ring has no rigidity, and the shape of the incoming material before grasping varies greatly, and it is difficult to accurately position the sealing ring during grasping; [0005] Third, the diameter and wire diameter of the sealing ring are relatively small. For example, for a rubber O-ring with an inner diameter of 10 mm and a wire diameter of 1 mm, it is difficult to grasp the seal...

AI Technical Summary

Problems solved by technology

[0003] First, the sealing ring is made of rubber material, which is soft and easy to deform. It is difficult to maintain the original circular shape when clamping. Therefore, it is not suitable to grasp the sealing ring by clamping;

[0004] Second, the sealing ring has no rigidity, and the shape of the incoming material before grasping varies greatly, and it is difficult to accurately position the sealing ring during grasping;

[0005] Third, the diameter and wire diameter of the sealing ring are relatively small. For example, for a rubber O-ring with an inner diameter of 10mm and a wire diameter of 1mm, it is difficult to grasp the sealing ring by adsorption.
