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

Abstract

The invention discloses a pallet nut gasket drilling mold, which comprises a drilling master mold, a double-ear pallet nut drilling mold, a butterfly-shaped pallet nut drilling mold and a single-ear pallet nut drilling mold. Three sets of independent drilling grooves are integrated, which are butterfly groove, double-ear groove and single-ear groove; the butterfly groove, double-ear groove and single-ear groove respectively correspond to the butterfly bracket nut drilling mold 1. Drilling mold for double-ear bracket nut and single-ear bracket nut. There are positioning pins in the groove of the drilling master mold. The positioning pins position each drilling male mold. The grooves of the corresponding drilling male molds inside the molds are clearance fit. The invention is simple in structure and easy to operate, and can ensure the accuracy of rivet hole positions when drilling holes with different types of supporting plate nut gaskets, and the drilling mold is simple to make, easy to operate, and can improve work efficiency. .

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...
