Abstract
The invention discloses a sealing ring bonding auxiliary tool and a sealing ring bonding method. The sealing ring bonding auxiliary tool at least comprises two O-shaped sealing ring bonding structures. One O-shaped sealing ring bonding structure comprises a cutting area, cutting constraint double grooves and a bonding constraint groove. The other O-shaped sealing ring bonding structure comprises abonding constraint groove, cutting constraint double grooves and a cutting area. Each structure is applicable to bonding of a wire diameter O-shaped sealing ring. Through the sealing ring bonding auxiliary tool, the problems that the fitness degree of the bonding cutting surfaces of existing large non-standard O-shaped sealing rings is not high and the bonding surfaces are connected in a staggered mode are solved. The sealing ring bonding auxiliary tool has the beneficial effects that the bonding surfaces of the O-shaped sealing rings are accurate, the bonding strength is high, the sealing effect is good, the service life is long, and the tool is easy to operate.
Description
【Technical field】 [0001] The invention belongs to the field of mechanical seals, and relates to an auxiliary tool for bonding a sealing ring and a method for bonding the sealing ring. 【Background technique】 [0002] O-rings are widely used in pressure vessels, power equipment, pulse power drive sources and other equipment, and are mainly used for oil, gas and water isolation. There are no standard products for O-rings with a diameter of φ700mm or more, and non-calibration is required. The processing cycle is long and the cost is high, which is not conducive to the development and use of large single-piece equipment. [0003] Most O-rings are glued and cut at 90°, 30° or 45°, and the bonding process is done manually or with the help of tooling. Manual operation, the bonding quality of the sealing surface is not easy to guarantee; tooling operation, the design accuracy of the tooling is high, and the general tooling design involves precision moving parts, and the operation is...
