Pressing module used for automatic hole manufacturing end effector

Abstract

The invention discloses a pressing module used for an automatic hole manufacturing end effector. The pressing module mainly comprises air cylinders, air cylinder supports, floating connectors, linear guide rails, sliding blocks, link plates, a presser foot mounting frame, a limiting sensor mounting frame, a limiting sensor, an annular presser foot, a rubber elastic washer, laser displacement sensors, a laser displacement sensor support and an end effector frame. The air cylinders, the floating connectors and the linear guide rails drive a presser foot device to achieve the pressing module used for the automatic hole manufacturing end effector; and in addition, the laser displacement sensor support on the presser foot device is designed to be in a triangular shape and provided with the laser displacement sensors, the tail end of the annular presser foot is connected with the elastic washer, and limiting sensor mounting frames and limiting sensors form mechanical limit limiting devices. According to the pressing module, the dynamic rigidity of a system can be enhanced, vibration generated when a robot manufactures holes is restrained, gaps between laminated wall plates are eliminated, burrs are restrained, and the hole manufacturing precision can be effectively guaranteed.

Description

Technical field[0001]The present invention relates to the field of aircraft assembly, and more particularly to a compression module for automatic aperture end effectors.Background technique[0002]In the aviation manufacturing industry, it is often used to assemble the automatic drilling machine, automatic drilling riveting machine, etc., to improve the degree of automation of the aircraft assembly, due to the plane of the aircraft Difference, at the same time, in the process of the hole, the skin will be interfected with the sliding and vibration of the robot's end effector relative to the wall panel, which can generate a deformation of the aircraft wall panel to affect the drilling accuracy of the aircraft wall panel. The pressing module for automatic hole end effectors is particularly important.[0003]In the robot terminator, the compression module is often mounted on the end effector end, and the cylinder is synchronously pushed by the cylinder on both sides of the end effector to ...

AI Technical Summary

Problems solved by technology

[0002] In the aviation manufacturing industry, end effectors such as automatic drilling machines and automatic drilling and riveting machines mounted on industrial robots or machine tools are usually used for assembly to improve the automation of aircraft assembly. At the same time, during the hole making process, the skin will be disturbed by the sliding and vibration of the robot end effector relative to the panel parts, which will cause deformation of the workpiece to be processed and affect the drilling accuracy of the aircraft panel. Therefore, a The compression module for automatic hole making end effector is particularly important
