Abstract

The invention discloses a string core clamp tightening tool. The tool comprises a frame handle, a sleeve, a pin, a quick-changing bush and a compressing screw; a hexagonal socket I and a compression screw hole are arranged on the frame handle, and the hexagonal socket I is a hollow through hole; a hexagonal socket II is arranged in the sleeve, the sleeve is a tubular through hole, and a round hole is formed in the sleeve; the pin penetrates the round hole in the sleeve, the sleeve and the frame handle are combined through the quick-changing bush, and the compressing screw compresses the quick-changing bush through the compressing screw hole; and the string core clamp tightening tool is simple in structural design, ingenious in conception and capable of rapidly tightening a string core clamp; and the problem that the appearance of a wing whole oil tank is extremely poor is solved, and the thickness of a rubber layer is effectively controlled. The product quality is ensured, the work efficiency is improved, and labor intensity of workers is reduced.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a core clamp tightening tool for fixing the glue-coated rear wall plate of the integral fuel tank of an aircraft wing. Background technique [0002] The shape requirements of the overall fuel tank of the aircraft wing are relatively strict, and one of the important factors affecting the shape of the overall fuel tank of the wing is the thickness of the glue layer of the sealant. During the sealing and riveting process of the integral fuel tank of the aircraft wing, the control of the adhesive layer is particularly important. The thickness of the adhesive layer must be strictly controlled within 0.3mm to ensure that the product shape meets the design requirements. However, it is difficult for ordinary wind trigger guns to fully tighten the core clamp, and often can be tightened by 1 to 2 turns, resulting in the thickness of the adhesive layer not being ef...
