Dismounting and mounting device for slotted countersunk head nut of aircraft canopy

Abstract

The invention discloses a dismounting and mounting device for a slotted countersunk head nut of an aircraft canopy, can realize effective dismounting and mounting of the slotted countersunk head nut, and relates to the technical field of aviation equipment. According to the dismounting and mounting device for the slotted countersunk head nut of the aircraft canopy, the end part of the countersunk head nut is provided with a slotted groove; the device comprises two tooth heads, a stress application rod and a wrench handle. Round holes, U-shaped notches and sharp teeth are arranged on the two tooth heads; the two tooth heads are cylindrical, the round holes are formed in the tooth heads, the two inclined U-shaped notches are formed in the head parts, the two sharp teeth are formed, and the width size of the sharp teeth is increased from the root parts. The stress application rod and the two tooth heads are integrally manufactured, the stress application rod is in a square column shape, a stress application rod rivet hole is formed in the tail end of the stress application rod, and a rivet is matched with the rivet hole to fixedly connect the stress application rod with the wrench handle. The wrench handle is cylindrical, a square hole matched with the stress application rod is formed in the wrench handle, and the stress application rod is inserted into the square hole.

Description

technical field [0001] The invention relates to the technical field of aviation equipment, in particular to a dismounting device for a slotted countersunk nut of an aircraft canopy. Background technique [0002] When repairing the canopy of JJ-9 aircraft, it is necessary to dismantle the canopy glass for replacement and repair. There are 24 slotted countersunk nuts Q / 6A1-402-M6 on the canopy frame. Before disassembling the canopy glass, it is necessary to First disassemble the nut, and then install and fix the nut after the glass is installed. Because of the special shape of the nut, the existing tools cannot be disassembled, and the canopy repair work cannot be carried out normally.

Problems solved by technology

[0002] When repairing the canopy of JJ-9 aircraft, it is necessary to disassemble the canopy glass for replacement and repair. There are 24 slotted countersunk nuts Q / 6A1-402-M6 on the canopy frame. Before disassembling the canopy glass, it is necessary to First disassemble the nut. After the glass is installed, the nut needs to be installed and fixed. Because of the special shape of the nut, the existing tools cannot be disassembled and assembled, and the canopy repair work cannot be carried out normally.

[0003] This model is the first overhaul model of the air force equipment system, and the aircraft has entered the first overhaul period. The nut has a special shape, and the existing tools cannot be disassembled, and the canopy repair work cannot be carried out normally.

[0004] There is an urgent need for a wrench that can effectively disassemble and assemble the slotted counter nut Q / 6A1-402, and no related device has been found in the market and the entire industry
