Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figure 1-4 Shown, the assembly method of O-ring of the present invention comprises the steps:

[0023] (1) Ring release: place the O-shaped sealing ring on the support ring cone, either manually or by an automatic feeding device for the front sealing ring.

[0024] (2) Ring preparation: The ring cylinder drives the ring cone to go deep into the ring channel in the ring cone cavity, and the ring channel, air inlet and exhaust channel are arranged in the ring cone cavity ;

[0025] (3) Support ring: Tightly cover the ring transfer guide sleeve 2 outside the support ring cone 5, the air inlet 11 starts to intake air, and under the action of the air flow, the O-shaped sealing ring 100 moves upward along the support ring cone 5 to the transfer ring On the guide sleeve 2, the stripping sleeve 3 is set outside the ring transfer guide s...

Abstract

The invention discloses an assembling method for an O-shaped sealing ring. Firstly, the O-shaped sealing ring is placed on a ring supporting cone in advance (at the moment, the O-shaped sealing ring is not stretched), then the ring supporting cone is inserted into a ring supporting cone cavity, air flow filled through an air inlet enters a ring supporting passage, the light O-shaped sealing ring can be pushed upwards onto a ring moving guide sleeve sleeving the ring supporting cone under the action of the air flow, a ring releasing sleeve sleeving the ring moving guide sleeve can limit an extreme position of upward movement of the O-shaped sealing ring, i.e. limit a supporting size of the O-shaped sealing ring, and the O-shaped sealing ring is automatically sleeved and supported by the ring moving guide sleeve; then the supported O-shaped sealing ring is moved to a ring sleeving station, a ring sleeving plate pushes a ring release spring guide pillar to move downwards under the action of a ring sleeving cylinder, and the spring guide pillar pushes the ring release sleeve to move downwards along the ring moving guide sleeve to push the O-shaped sealing ring away from the ring moving guide sleeve and send the O-shaped sealing ring to a designated sealing ring mounting position on a workpiece to be assembled so as to implement ring sleeving. Assembling efficiency and a qualified rate are high, and basically, no damage to the O-shaped sealing ring is caused.

Description

technical field [0001] The invention relates to an assembly method of an O-shaped sealing ring. Background technique [0002] The O-ring is the most commonly used seal ring. O-ring seal is the most widely used seal on various mechanical equipment. Its cross-sectional structure is extremely simple, and it has self-sealing function and reliable sealing performance. It is mainly used for static seal and reciprocating motion seal. [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, stretch the O-shaped sealing ring and cross any end of the workpiece before inserting it into the groove. As the shape of the workpiece becomes smaller and smaller, the size of the O-ring is also smaller and smaller, which brings great inconvenience to the installation work. The assembly of the existing O-shaped seal rings generally relies on manual assembly, resulting in a high failu...
