Description
Technical Field
The application belongs to the field of sealing tools of aircraft assembly manufacturing technologies, and particularly relates to a sealing cap device for a high-lock bolt package.
Background
In modern aircraft assembly connection, the high-locking bolt is widely applied, so that the strength of the aircraft structure is effectively improved, and the service life of the aircraft structure is prolonged. In order to prevent corrosion, abrasion or discharge, a sealing material is filled between the head of the high-locking bolt and the matching surface of the high-locking bolt in the assembly process to form a sealing packet. At present, the sealing bag mainly has the problems of eccentricity, secondary pollution at the top glue overflow hole and the like.
The existing sealing technology of the high-locking bolt mainly comprises two types:
the first is to fill the sealant with a glue gun, then manually dip in isopropanol solvent or soapy water for repair or repair the sealant with a simple tool to achieve the shape of the sealed package. The appearance of the locking assembly after the high-locking bolt is installed is complex, the viscosity of the sealant is high, the sealing operation difficulty is high, the manual shape correction efficiency is low, and the formed sealing bag has the quality problems of unqualified sealing size, poor appearance consistency and the like. In addition, isopropanol solution or soapy water is needed for shaping, and if the isopropanol solution or soapy water is improperly used, the sealant can be bonded and fail, so that quality accidents are caused.
And the second is to form a sealing packet meeting the requirements by adopting a sealing cap glue injection back-off mode. Firstly, injecting sealant into a sealing cap by using a sealant injection gun, wherein the injected sealant is about 2/3 of the volume of the sealing cap, reversely buckling the sealing cap on a high-lock bolt head, enabling the bottom edge of the sealing cap to be in contact with the matching surface of the sealing cap, lightly pressing the sealing cap to enable the sealant to be extruded out of the edge of the bottom of the sealing cap in a uniform and continuous mode, and partially preventing the sealing cap from leaving air at the top to influence the appearance shape of a sealing packet, so that a sealant overflow hole is formed in the top end of the sealing cap, and a small amount of sealant is extruded out when the sealing cap is lightly pressed, thereby ensuring the integrity of the shape of the sealing packet. The method solves the problems of inconsistent appearance and high operation difficulty in the first mode, but the method still has the eccentric problem due to the fact that the axle center of the high-lock bolt cannot be positioned, so that the thickness of a sealing bag on the high-lock bolt is uneven, and the sealing effect is poor. And the glue injection amount of the sealing cap used in the method is determined visually, so that the risk of size out-of-tolerance exists. Therefore, the novel sealing cap which is convenient to operate, good in sealing effect and good in appearance consistency and can optimally solve the problem of encapsulation efficiency, the eccentric problem, the secondary pollution and the appearance quality of the high-lock bolt is very necessary.
The publication No. CN108943516B discloses a manufacturing method of a high-lock bolt sealing cap of an integral oil tank of an airplane. In the manufacturing method of the sealing cap, the die consists of an upper die of a concave cavity and a lower die of a stepped conical cavity, and the die is of a split type structure and needs to be used in combination with the upper die and the lower die. In the manufacturing process of the sealing cap, two forming modes exist, when a mode of injecting glue through a glue injection hole is adopted, the glue injection hole of the upper die is not protected, and the sealing agent is polluted by sundries such as dust and the like when being solidified; when the sealing mode that the upper die of the concave cavity is used for injecting glue and then the concave cavity is reversely buckled at the head of the high-locking bolt is adopted, the glue injection hole is free of a plug, a tool or a finger is needed to be additionally matched for blocking operation, and the risk of glue leakage exists.
