AI Technical Summary

Technical Problem

The prior art is cumbersome when drilling holes in the center of the propeller hub of the aircraft, and the drilling efficiency is low, and the clamping mechanism is not convenient to adjust according to the propeller specifications.

Method used

An aircraft propeller drilling device is designed, including a base, a gantry, a lifting plate, a motor, a drill rod, a cylinder, a radial clamping assembly and a longitudinal clamping assembly. The lifting plate drives the drill rod downward and the cylinder pushes the lifting plate downward, and drives the pressure lifting mechanism to work, so that the clamping assembly clamps the propeller hub and the blade simultaneously.

Benefits of technology

It realizes rapid clamping and drilling of propeller hubs and blades without tedious operation. It is suitable for propellers with different diameter specifications and different surface blades of curvature, improving working efficiency and operation convenience.

Abstract

The invention relates to an aircraft propeller punching device which comprises a base fixed with a portal frame, a lifting plate slidably connected to a stand column of the portal frame, a motor fixed to the lifting plate, a drill rod in transmission connection with the output shaft end of the motor, an air cylinder fixed to a cross beam of the portal frame, and the lifting plate fixedly connected to the piston rod end of the air cylinder. A supporting cylinder base is fixed to the base, a radial clamping assembly is arranged on the supporting cylinder base, a support is fixed to the peripheral wall of the supporting cylinder base, a pressing and lifting mechanism is arranged on the support, a longitudinal clamping assembly used for pressing propeller blades is arranged on the support, and the pressing and lifting mechanism is in transmission connection with the radial clamping assembly and the longitudinal clamping assembly. A third sliding barrel and a fourth sliding barrel are fixed to the base, the third sliding barrel is communicated with the pressing and lifting mechanism through a first air pipe, and the fourth sliding barrel is communicated with the radial clamping assembly and the longitudinal clamping assembly through a second air pipe. According to the aircraft propeller punching device, synchronous clamping of a hub and blades of a propeller is achieved, and the operation efficiency is greatly improved.
