Description

Technical Field

[0001] The invention relates to a quick installation device for a butterfly-shaped cable clamp, which is suitable for quickly completing the installation of the butterfly-shaped cable clamp in a narrow space of an aircraft during the aircraft cable assembly process. Background Art

[0002] When installing a butterfly-shaped cable clamp on an aircraft, usually four bundles of cables are inserted into the butterfly clamp respectively, and the operator presses the clamp with his fingers. When the clamp is pressed into place, the corresponding mounting bolt is placed into the clamp groove hole, and the bolt is tightened with a "slotted" screwdriver to complete the connection and installation between the clamp and the fuselage structure. When assembling in the narrow space of an aircraft, the operator uses a screwdriver tool with one hand and presses the clamp with the other hand while supporting the nut. There is a risk of the bolt and nut falling off due to the rebound of the clamp caused by the loss of hand strength to fix the clamp. After the bolt and nut fall off, the clamp needs to be pressed again for repeated installation. After the small batch and mass production of aircraft, this pure manual operation method without any tools is a great loss of the operator's physical strength. Not only is the production efficiency low, but the falling of bolts is also easy to cause redundant objects, thus bringing quality risks to the aircraft. Summary of the invention
