Embodiment Construction

[0018] Attached below figure 1 The present invention will be further described.

[0019] An auxiliary tooling for applying sealant to the edge of the lower pound column reinforcement of a passenger-to-cargo aircraft, including: a bracket 1; several pairs of tape fixing rings 26 coaxially arranged, and a gap adjustment is arranged between the two tape fixing rings 26 of each pair device, each tape fixing ring 26 is rotatably installed in the bracket 1 through the central shaft 13 connected coaxially; the tracking wheel 16 is rotatably mounted on the lower end of the tape fixing ring 26, and its rotation axis is parallel to the axis of the central shaft 13; And the tape fixing device is arranged on the tape fixing ring 26 and is used for fixing the inner ring of the tape inserted on the tape fixing ring 26 . During use, the adhesive tape is fixed on the adhesive tape fixing ring 26 through the adhesive tape fixing device, and then the gap between the two inner ferrules of each ...

Abstract

An assist tool for spraying sealant to an edge of a stiffener on a weighing pillar of a passenger-into-cargo airplane comprises: a support; a plurality of pairs of coaxially arranged tape fixing rings, wherein a clearance adjuster is disposed between two tape fixing rings in each pair and each tape fixing ring is rotationally mounted in the support through a coaxially connected center shaft; tracing wheels that are rotationally mounted at the lower ends of the tape fixing rings, wherein a rotational axis of each tracing wheel is parallel to the axis of the center shaft; and tape fixing devices disposed on the tape fixing rings and which are used for fixing tapes inserted onto the tape fixing rings. The clearance between two tape inner ferrules in each pair is adjusted through one clearance adjuster, so that a suitable paper tape clearance is obtained; the tracing wheels rotationally move along the edges of the skin stiffeners, a paper tape is continuously peeled from a tape core and stuck to the surfaces of the stiffeners on two sides of a tracing wheel rail during this process, and application and compression of the paper tape is finished. Tape sticking efficiency and precision are improved.

Description

technical field [0001] The invention relates to an auxiliary tooling for coating the edge sealant of the lower weighing column reinforcement sheet of a passenger-to-cargo aircraft. Background technique [0002] After completing the installation of the lower pound column reinforcement sheet of the Boeing 737-300 passenger-to-cargo aircraft, it is necessary to coat the edge of the reinforcement sheet with sealant, which can improve the aerodynamic smoothness of the area and prevent rainwater, dust, etc. Corrosion of relevant structural components affects structural strength. During the implementation of the above process, it is necessary to cover the edge of the reinforcing sheet with a gap and then cover it with paper tape to prevent the sealant from polluting other irrelevant areas. The implementation of the above process is now mostly done by manual posting, which has low work efficiency and easily leads to uneven posting gaps. Contents of the invention [0003] In orde...
