Positioning and drilling tool for circular covering cap and using method thereof

Abstract

The invention provides a positioning and drilling tool for a circular covering cap and a using method thereof, and belongs to the technical field of machine manufacturing and assembling. The tool comprises a positioning platform, a rubber pad, a longitudinal V-shaped clamping device, a transverse sliding rail, a Y-axis zero pointer, a Y-axis rotating pointer, an angle ruler disc, a Y-axis slidingsupport, a locking screw, a guide hole positioning block, a jackscrew, an alloy bushing, a Y-axis sliding guide rail deflection locking device, an X-axis locking device, a transverse V-shaped clampingdevice and a transverse sliding support seat. The auxiliary positioning and drilling tool for rapidly drilling the circular covering cap is high in universality and practicability and simple in operation difficulty, the working efficiency can be greatly improved, manual control factors of the product quality are controlled in an auxiliary mode by adopting a mechanical device, and the product quality is guaranteed while the stability of the tool is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing and assembly, and is mainly used to solve the difficult problems such as the difficulty in positioning the fixing nail holes of the circular skin flap (hereinafter referred to as "the flap") on the aircraft, and the large deviation of the center size of the hole after drilling. Because the tooling adopts 3-point positioning method, the center of the cover can be quickly determined, and then according to the length of the center of each fixed point on the cover from the center of the cover and the deflection angle of the X axis, the aircraft circle can be completed efficiently and with high quality. Precise positioning, drilling, and nesting of the fixing nail holes of the shaped mouth cover. Background technique [0002] At present, in the process of aircraft manufacturing, for the convenience of pre-installation and post-maintenance, detachable covers are used for the installatio...

AI Technical Summary

Problems solved by technology

The current conventional method is to use a drill bit that meets the size requirements to directly expand the hole directly perpendicular to the guide hole of the skin cover for the cover that already has a small guide hole. When using a hand-held pneumatic drill, when the operator is drilling, he must not only overcome the centrifugal vibration force generated by the pneumatic drill during rotation, but also ensure that the drill bit is perpendicular to the mouth cover at all times, otherwise the round hole may be drilled into an ellipse hole, resulting in poor product quality
