Assembly method of seal ring

Abstract

The invention discloses an assembly method of a seal ring. The method is achieved by a taper-lock and a thrust ring, wherein the thrust ring is sleeved outside the taper-lock and concentric with the taper-lock; the thrust ring and the taper-lock can oppositely move along the axes; the thrust ring can move along with the taper-lock; the positions of the thrust ring and the taper-lock are kept in relative rest to pick up the seal ring; the thrust ring also can axially move relative to the taper-lock, and pushes the seal ring; the taper-lock is in a structure which is divided into three parts from a cylinder along the axis, but not limited by 1 / 3; a reclaiming end can be hollowed out, so as to envelop a part of receptor; the reclaiming end also can be not hollowed out if the receptor does not need to be enveloped; the taper-lock can expand in a radial direction or conical degree; the inner diameter of the thrust ring is a little greater than the outer diameter of the expanded taper-lock. The assembly method of the seal ring is simple and convenient to operate, safe and reliable, and strong in common availability, and is applied to semi-automatic and automatic equipments for assembling the seal ring; manpower can be saved; the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of mechanical design and manufacture and its automation, in particular to a sealing ring assembly technology for a valve stem. Background technique [0002] Sealing rings are widely used. At present, they are mainly assembled by manpower. The efficiency of assembly is low, the consumption of manpower is large, and the cost of manpower is high. Contents of the invention [0003] The purpose of the present invention is to provide a sealing ring assembly method, which is easy to operate, safe and reliable, and has strong commonality. It is applied to semi-automatic and automatic equipment for sealing ring assembly, which can save manpower and improve production efficiency. [0004] The assembly method of the seal ring is realized by means of an expansion sleeve and a push ring; the push ring is set outside the expansion sleeve, the two are coaxial, and the two can move relatively along the axis; the push ring can be mo...
