Installation device for O-shaped seal ring

Abstract

The invention provides an installation device for an O-shaped seal ring. The installation device for the O-shaped seal ring mainly comprises a plurality of ring hooking pieces, a radial drive mechanism and a plurality of extendable ejector rods. The multiple ring hooking pieces are evenly distributed around the same center axis, the ends, close to the center axis, of the ring hooking pieces are provided with hook columns, the multiple hook columns are parallel to the center axis, and the outer side faces of the hook columns are used for arranging the seal ring to be expanded in a sleeving manner; the radial drive mechanism can drive all the ring hooking pieces to keep away from the center axis in the radial direction at the same time, and a space for installing a workpiece is formed on the inner sides of the multiple ring hooking pieces; and the multiple extendable ejector rods are arranged on the periphery of the center axis in a parallel manner, each ejector rod corresponds to the gap between the two adjacent hook columns, and the multiple ejector rods carry out upward ejecting at the same time and can push the seal ring away from the hook columns so that the seal ring can be arranged on the workpiece in a sleeving manner. The installation device for the O-shaped seal ring can achieve automatic installation of the seal ring, the operation difficulty and intensity of workers are lowered, the working efficiency can be improved, and the installation quality is stable and consistent.

Description

technical field [0001] The invention relates to an O-shaped sealing ring installation device, in particular to an O-shaped sealing ring installation device capable of fitting the O-shaped sealing ring on a workpiece with a cylindrical structure. Background technique [0002] In the process of assembling mechanical parts, it often involves the assembly of the sealing ring on the workpiece with a cylindrical structure. In the prior art, when the sealing ring is installed on this cylindrical structure, it is mostly manual work. , that is: the assembler first stretches the sealing ring, and then inserts the sealing ring into the component installation part. Has the following disadvantages: [0003] 1. If the outer size of the sealing ring is too small, it is difficult for the operator to insert the hand, so it is difficult to assemble it directly by hand; if the cross-sectional size of the sealing ring is too large, it will be very difficult to open the sealing ring manually, a...

AI Technical Summary

Problems solved by technology

[0003] 1. If the outer dimension of the sealing ring is too small, it is difficult for the operator to insert the hand, so it is difficult to assemble directly by hand; if the cross-sectional size of the sealing ring is too large, it will be very difficult to manually open the sealing ring, and put the sealing ring on the workpiece It is more difficult; if it is batch sealing ring assembly, repeated manual work, the labor intensity is very high, and the work efficiency is low

[0004] 2. The quality and efficiency of manual assembly of sealing rings mainly depends on many human factors such as the operator's operating skills, proficiency and even fatigue, so there are many uncertainties, so the installation quality is unstable
