Problems solved by technology

As the shape of the workpiece is getting smaller and smaller, the size of the O-ring is getting smaller and smaller, which brings great inconvenience to the installation work.
[0004] The assembly of the existing O-rings generally relies on manual assembly, resulting in a high failure rate of the product, and the assembly efficiency is limited, which is time-consuming and laborious, and greatly increases the production cost.
At the same time, due to the

Abstract

The invention discloses an automatic assembling device for valve rod sealing rings. The automatic assembling device comprises an automatic valve rod feeding device and two sets of automatic sealing ring assembling devices, wherein the automatic valve rod feeding device sequentially moves valve rods to positions to be assembled for realizing the automatic feeding of the valve rods; after the automatic valve rod feeding device positions the valve rods and tightly presses the valve rods, the automatic feeding and ring supporting actions of O-shaped sealing rings are respectively completed by the two sets of automatic sealing ring assembling devices, in addition, the supported O-shaped sealing rings are pushed into grooves of the valve rods in the two positions to be assembled of the valve rods, and the automatic assembly of the two sealing rings is completed; finally, the assembled valve rods are conveyed and discharged. The automatic assembling device has the advantages that the assembly automation of the valve rod sealing rings can be realized, the defects of low assembly speed and automation assembly adaption difficulty of manual operation can be overcome, the product qualification rate and the assembly efficiency are greatly improved, and in addition, the work intensity, the labor and the production cost are reduced. The invention also discloses an automatic assembling method for the valve rod sealing rings.

Description

technical field [0001] The invention relates to an automatic assembly device, in particular to an automatic assembly device for a sealing ring of a valve stem. The invention also relates to an automatic assembly method for the sealing ring of the valve stem. Background technique [0002] O-rings are the most commonly used seal rings. O-ring is the most widely used seal on various mechanical equipment. Its cross-sectional structure is extremely simple, and it has a self-sealing function and reliable sealing performance. It is mainly used for static sealing and reciprocating motion sealing. [0003] In order to improve the sealing effect on the workpiece, it is necessary to insert the O-shaped sealing ring into the groove of the workpiece. When installing, the O-shaped sealing ring should be stretched and passed over any end of the workpiece before being inserted into the groove. As the shape of the workpiece is getting smaller and smaller, the size of the O-ring is also get...
