Description

Technical Field

[0001] The present invention relates to the field of aerospace technology, and in particular to an aerospace fire-resistant mica tape splicing device and method. Background Art

[0002] Aviation refers to the navigation of manned or unmanned aircraft within the Earth's atmosphere; aerospace refers to the navigation of manned or unmanned spacecraft beyond the Earth's atmosphere, also known as space flight or astronautics. To expand social production, humanity must inevitably open up new spaces for its activities. From land to sea, from the ocean to the atmosphere, and then to outer space, this is the process of humanity gradually expanding its scope of activities. In the aerospace field, there are aerospace cables. During the wrapping process of the aerospace cable sheath, mica tape is loaded between the upper and lower sets of fiberglass cloth. Mica tape, also known as refractory mica tape, is produced by a mica taping machine and is a refractory insulating material. It can be divided into mica tape for motors and cables by application, and into double-sided tape, single-sided tape, three-in-one tape, dual-film tape, and single-film tape by structure. Based on the mica content, it can be further divided into synthetic mica tape, phlogopite tape, and muscovite tape. Mica tape for fire-resistant safety cables is a high-performance mica insulation product with excellent high-temperature and combustion resistance.

[0003] During the production process of existing mica tapes, the mica tapes are pre-loaded inside two sets of fiberglass cloths. After production, there are usually some scraps at the disconnection points of the mica tape assembly. In order to ensure the convenience of its continued connection, it is necessary to shear them. The existing shearing device has a relatively simple structure, usually a single oblique cut and a vertical cut. This method makes it difficult to connect the mica tape by cold pressing when connecting it, and its contact area is narrow, which makes it easy for it to loosen, so it has certain limitations.

[0004] The existing splicing device usually requires manual pressing when limiting the mica tape, and the manual pressing method is prone to slipping, and it needs to be cold-pressed after manual pressing. The process needs to be done step by step, which is relatively cumbersome and has certain operational inconveniences. Summary of the Invention

[0017] Preferably, two groups of arc-shaped rotating plates rotate inside the closed-loop slide, and a No. 1 torsion spring is fixed between the two groups of arc-shaped rotating plates and the connecting device body. A reset rod rotates below the arc-shaped rotating plate inside the closed-loop slide, and a No. 2 torsion spring is fixed between the reset rod and the connecting device body.

[0025] 1. The present invention solves the problem of inconvenience caused by conventional manual pressing by arranging a pull rod, an inner slider, a slide plate, a limit plate, a limit pressure plate, a limit spring, a guide rotating rod, and a guide protrusion. By pressing the pull rod, the guide protrusion can be positioned below the two sets of arc-shaped rotating plates. At this time, the two sets of limit plates can drive the two sets of limit pressure plates to contact the top of the mica tape, thereby limiting it and playing a limiting role. The arrangement of the first torsion spring and the arc-shaped rotating plate can play a self-locking role, avoiding the problems of poor stability and inconvenience in operation of conventional manual pressing.

[0026] 2. The present invention solves the problem of complicated operation steps in the existing manual limit and subsequent cold pressing by arranging the pull rod, inner slider, slide plate, guide rotating rod, guide protrusion, pressing block and guide assembly. The mica tape can be limited by pressing the pull rod for the first time, and then the pressing block can be used to cold press the mica tape by continuously pressing the pull rod. When the cold pressing is completed, the pull rod can be released. When the guide protrusion is located on the side of the reset rod, the limit pressure plate and the pressing block can be reset, achieving the effect of simultaneous operation.

[0027] 3. The present invention solves the problem of insufficient adhesion after cold pressing due to small contact area caused by the relatively simple structure of the existing splicing device through the arrangement of a threaded rod, a threaded disk, a magnetic boss, a No. 1 pushing surface, a No. 2 pushing surface, a No. 3 pushing surface, a cutter head, a magnetic guide block, a cutting guide groove, a rack, a transmission gear, a No. 1 bevel gear, a damping disk, a damping block, a return spring, a side gear, a No. 2 bevel gear and a side rack.

10. A method for splicing the aerospace fire-resistant mica tape splicing device according to claim 9, characterized in that: The specific method steps are as follows; Step 1: The mica tape can be placed on the top of the limiting pressing seat (130); Step 2: At this time, the pull rod (310) can be pressed, and then the guide protrusion (351) can be located below the two sets of arc-shaped rotating plates (410). At this time, the two sets of limiting plates (330) can drive the two sets of limiting pressure plates (340) to contact the top of the mica tape and limit it; Step 3: At this time, the handle can be turned to drive the two sets of magnetic bosses (230) gradually close to the limiting pressure plate (340), so that the cutter head (240) can slide longitudinally to cut the fiberglass cloth. When the magnetic guide block (241) contacts the second pushing surface (232), the rack (250) and the transmission gear The contact of the wheel (260) can make the cutter head (240) slide horizontally, and the glass fiber tape on the outside thereof can be pushed to separate from the mica tape. When the magnetic guide block (241) contacts the third pushing surface (233), the mica tape can be cut; Step 4: Turn the handle to reset the two sets of cutter heads (240), and then pull the limiting slide bar to pull out the cut mica tape, place the mica tape to be continued on the top of the limiting pressing seat (130), and apply glue to its end, and then continue to press the pull rod (310) to make the pressing block (360) cold press the mica tape. After the cold pressing is completed, the pull rod (310) can be released to reset the limiting pressure plate (340) and the pressing block (360).
