Problems solved by technology
The rivet holes on the backing nut gasket need to be drilled manually with the standard backing nut as the drilling template, and then the hole is made after clamping with wire pliers. The above hole making method undoubtedly has low hole making efficiency, poor hole quality, and the gasket cannot Problems such as interchangeability and high scrap rate, and manual clamping cannot meet the fixing degree of the nut gasket of the backing plate, and the gasket often rotates with the air drill during drilling, which may cause the drill bit to break and even cause personal injury

The invention discloses an anchor nut gasket drilling die. The anchor nut gasket drilling die comprises a drilling female die, a double-lug anchor nut drill die, a butterfly-shaped anchor nut drill die and a single-lug anchor nut drill die. Three sets of independent drilling male die grooves are integrated in the drilling female die and include the butterfly-shaped groove, the double-lug groove and the single-lug groove. The butterfly-shaped groove, the double-lug groove and the single-lug groove correspond to the butterfly-shaped anchor nut drill die, the double-lug anchor nut drill die and the single-lug anchor nut drill die respectively. A positioning pin is arranged in a groove of the drilling female die and conducts positioning on drilling male dies. The drilling male dies are in clearance fit with the corresponding drilling male die grooves in the drilling female die in shape respectively. The anchor nut gasket drilling die is simple in structure, convenient to operate and capable of guaranteeing the accuracy degree of rivet holes when holes are drilled in different types of anchor nuts. Moreover, the drilling die is easy to manufacture, convenient to operate and capable of improving the operating efficiency. The gasket is matched with the drilling die.
Description
technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a drilling die for a pallet nut washer. Background technique [0002] During the assembly process of the aircraft, a large number of single-ear, double-ear, and wing-shaped bracket nut gaskets are used for compensation and connection of detachable structural components, and some special requirements are also assembled with multi-layer gaskets. The rivet holes on the backing nut gasket need to be drilled manually with the standard backing nut as the drilling template, and then the hole is made after clamping with wire pliers. The above hole making method undoubtedly has low hole making efficiency, poor hole quality, and the gasket cannot There are problems such as interchangeability and high scrap rate, and manual clamping cannot satisfy the fixing degree of the backing nut gasket. During drilling, the gasket often rotates with the air drill, which will cause the dri...
