Hi-lock nut installation robot end actuator and hi-lock nut installation method thereof

Abstract

The invention discloses a hi-lock nut installation robot end actuator and a hi-lock nut installation method thereof. When hi-lock nuts are assembled manually, the labor intensity is large, and the installation efficiency is low. The hi-lock nut installation robot end actuator comprises a base, a feeding device, an installing device and a nut conveying device; the feeding device comprises a feedingdriving assembly, a guide rail, a ball screw and a rear sliding seat; the installing device comprises a socket wrench, a synchronous belt, a screwing driving assembly, a driving synchronous belt wheel, a driven synchronous belt wheel, a locking advancing and retreating plate, a spline shaft, a retreating air cylinder, a torque sensor, a stop shaft, a supporting box and a spline seat; and the nutconveying device comprises a pneumatic clamping jaw, a transposition air cylinder, a conveying pipeline, a charging air cylinder, a sleeve supporting seat, a front sliding seat, a mounting plate, a first connecting plate and a second connecting plate. According to the end actuator and the method, the conveying action, the transposition action, the screwing action and the hexagon head discharging action of the hi-lock nuts can be completed, and the automation degree is high.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing and automation thereof, and in particular relates to a high lock nut installation robot end effector and a high lock nut installation method thereof. Background technique [0002] In aircraft assembly connections, high-lock bolts and high-lock nuts are widely used. The high lock nut is composed of a round nut and a hexagonal head, with a thin neck broken groove in the middle. When the high lock nut is tightened, the inner hexagonal socket wrench is stuck on the hexagonal head of the nut, the outer hexagonal stop tool is inserted into the inner hexagonal hole at the end of the high lock bolt to stop, the socket wrench rotates and tightens the nut until the design pre-tightening force of the nut is reached , the broken neck groove on the nut is twisted off, and the installation of the high lock nut is completed. In the past, this task was mainly assembled manually, which was labor...

Problems solved by technology

In the past, this task was mainly assembled manually, which was labor-intensive and low-efficiency; some automatic drilling and riveting machines were used for installation, but the equipment was large in size, required a high degree of openness in the assembly space, and lacked flexibility and flexibility.
