Description
Technical Field
The utility model relates to a negative line layer board nut scope control device that polishes is applicable to the negative line layer board nut mounting process of all kinds of avionics products on the aircraft, is applied to among the aircraft assembly process equipment technical field.
Background
The negative line layer board nut of aircraft avionics equipment is connected on the organism, and negative line layer board nut is for guaranteeing to switch on with the organism structure is reliable, and the organism need polish the paint removal rather than the laminating installation face. The traditional installation process directly uses a grinding tool to mechanically grind and remove paint on the nut part of the preset installation negative line supporting plate on the surface of the machine body, so the prior art has the following defects:
(1) the polishing area of the binding surface of the nut body of the negative line supporting plate is difficult to control. The technical requirement of the negative line support plate nut of the aircraft avionics device allows the grinding area of the binding surface of the aircraft body to be 2-3 mm larger than the contour of the bottom surface of the negative line support plate nut, but actually, due to manual operation, the grinding area is difficult to accurately control a grinding tool, and the grinding area is ensured.
(2) The shape of the grinding area of the binding surface of the nut body of the negative line supporting plate is difficult to control. The grinding tool is used for manually grinding the joint surface of the negative line supporting plate nut and the machine body, the grinding shapes are different, and the appearance quality of a product is influenced.
Disclosure of Invention
The utility model aims at providing a device of negative line layer board nut binding face control scope of polishing on organism to solve the problem of the difficult control of negative line layer board nut organism binding face regional size of polishing, shape.
The utility model discloses technical scheme:
the utility model provides a negative line layer board nut scope of polishing controlling means, includes appearance board, handle, bolt hole locating pin and rivet hole locating pin, appearance board outline is the same with negative line layer board nut bottom surface outline, and the size adds 2.5mm for negative line layer board nut bottom surface outline, and one side of appearance board is equipped with the handle, and the opposite side of appearance board is equipped with the bolt hole locating pin that corresponds negative line layer board nut bolt hole and at least one rivet hole locating pin that corresponds negative line layer board nut rivet hole.
Preferably, the bolt hole positioning pin and the rivet hole positioning pin are both metal cylindrical pins, the outer diameter of the bolt hole positioning pin is consistent with the inner diameter of the negative line support plate nut bolt hole, and the outer diameter of the rivet hole positioning pin is consistent with the inner diameter of the negative line support plate nut rivet hole.
Preferably, the outer plate is a stainless steel flat plate structure, and the thickness is 2 mm.
The utility model discloses simple structure, convenient to use, can complement in each type negative line layer board nut, the regional size of polishing, the shape of accurate control negative line layer board nut and organism binding face are favorable to improving that the product structure is anticorrosive, appearance quality, also has the improvement to work efficiency.
