[0003] The pallet nut drilling jig is a self-made special tool that is frequently used in the field of aircraft assembly and manufacturing. The traditional pallet nut drilling jig is affected by its own structure (the drilling template is square, the handle is 180 degrees from the drilling template), and cannot complete certain tasks. Drilling of nut rivet holes in some narrow spaces
And the drilling jig needs to be used front and back to drill two rivet holes, which is inconvenient to use and the drilling efficiency is affected

Embodiment Construction
[0018] The present invention will be further described below in combination with specific embodiments.
[0019] A pallet nut drilling template comprises a cylindrical drilling template 1, a bolt hole positioning pin 2, a retaining spring 3, a rivet hole positioning pin 4, a spring 5, and a handle 6. Two rivet holes, A7 and B8, are set on the template 1, respectively, and two rivet holes are drilled in sequence, the first rivet hole is drilled in the drill hole A7, and the second rivet hole is drilled in the drill hole B8 . The drill template 1 is made of steel after quenching and surface oxidation treatment, the thickness is 5 mm, and the roughness of the lower surface of the drill template 1 is 1.6. The bolt hole positioning pin 2 is used to realize the positioning of the bolt hole. The size of the bolt hole positioning pin 2 is determined according to the bolt hole of the supporting plate nut. The two are a small clearance fit, and the bolt hole positioning pin 2 and the dr...

The invention discloses a novel anchor nut drill jig and belongs to the technical field of aircraft assembling and manufacturing. A drill plate of the novel anchor nut drill jig is provided with two drill jig holes used for drilling two rivet holes in order. A bolt hole positioning pin is used for achieving positioning of a bolt hole, is in small clearance fit with the bolt hole of an anchor nut and is connected with the drill plate through a clamp spring. A rivet hole positioning pin is used for achieving positioning of the first rivet hole and is in small clearance fit with the rivet hole of the anchor nut. The rivet hole positioning pin is in clearance fit with the drill plate, and the effect that the rivet hole positioning pin rotates freely can be ensured. A spring is mounted between the rivet hole positioning pin and the drill plate. A handle is connected with the drill plate through a welding method, and the control degree is increased. The novel anchor nut drill jig is simple in structure and low in cost, the requirement of drilling the rivet holes of the anchor nut in a small and narrow space can be met, and the drilling precision is ensured; and traditional drill jig forward and reverse usage is changed into rotational usage, and the drilling efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of aircraft assembly and manufacturing, and relates to a pallet nut drilling mold. Background technique [0002] With the vigorous development of China's aviation industry, the aircraft assembly manufacturing industry, especially civil aircraft and general aircraft assembly manufacturing, is gradually moving towards higher precision and higher efficiency, which requires the tools used in the assembly manufacturing field to be On the premise of satisfying the machining accuracy, it should be easy to operate and increase the production rate. [0003] The pallet nut drilling jig is a self-made special tool that is frequently used in the field of aircraft assembly and manufacturing. The traditional pallet nut drilling jig is affected by its own structure (the drilling template is square, the handle is 180 degrees from the drilling template), and cannot complete certain tasks. Drilling of rivet holes for pallet ...
