Threaded positioning pin structure for unmanned aerial vehicle assembly

Abstract

The invention discloses a threaded positioning pin structure for unmanned aerial vehicle assembly. The threaded positioning pin structure is composed of a positioning pin body, an angle seat and a clamping plate assembly. The positioning pin body and the angle seat are matched and are symmetrically mounted at the inner sides of the end part of a clamping plate through bolt connection. The positioning pin body sequentially comprises an outer hexagonal section, a pin handle, a tool withdrawal groove, a positioning pin rod, a guide section and a threaded section from the upper end to the bottom,wherein the outer hexagonal section is connected with a pneumatic tool hexagonal pneumatic sleeve in a matched manner, the pin handle is a cylinder, on one hand, the outer hexagonal section is liftedto facilitate operation of a pneumatic tool, and on the other hand, manual operation is facilitated to achieve screwing into a supporting plate nut during installation. The tool withdrawal groove facilitates tool withdrawal during machining. The clamping plate assembly is accurately positioned on a wing assembling tool base through the positioning pin rod; and the threaded section is used for applying clamping force, so that the clamping plate assembly and the wing assembling tool base are connected into a whole. The threaded positioning pin structure can achieve the positioning and clamping functions and can also be rapidly operated through the pneumatic tool, so that the production efficiency is greatly improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to a UAV wing assembly tooling technology, in particular to a threaded positioning pin structure for UAV assembly. Background technique [0002] Chinese patent CN206190680U discloses "a threaded positioning pin mechanism for inspection tools". In CN206495864U and CN203500217U, "a kind of thread positioning pin" is respectively proposed, which is characterized in that it is suitable for fixture positioning, and the thread can only play a positioning function and cannot be clamped. Although the three positioning screws of GB828-88, GB829-88, and GB72-88 can play the role of positioning and clamping, their positioning accuracy is low and cannot meet the needs of the aviation manufacturing industry. [0003] Such as image 3 As shown, the clamp part 8 of the UAV wing assembly tool is generally composed of a clamp, two sets of corner seats, and several positioning parts. on, and clamp with 4 bolts. [0004] Aircraft are generally pr...
