An end effector for high-precision laser cutting of circular holes

Abstract

This utility model provides an end effector for high-precision laser cutting of circular holes, belonging to the field of laser processing equipment technology. It includes: a rotary drive mechanism comprising a servo motor, a transmission assembly, and a rotary platform; the servo motor is connected to the rotary platform via the transmission assembly; a mounting bracket has a mounting area with an optical axis reference position within the mounting area, the optical axis reference position being eccentrically positioned relative to the rotation axis of the rotary platform; when the rotary platform performs circular motion, the optical axis reference position performs circular motion with the rotation axis of the rotary platform as its center; the advantages of this utility model are: the laser cutting head can be fixed on the mounting bracket, and the servo motor can drive the laser cutting head to perform high-precision circular motion via the rotary platform, thereby ensuring that the cut circular hole has high precision, effectively avoiding the hole diameter deviation and out-of-roundness problems caused by insufficient robot motion precision in the prior art, and meeting the needs of precision machining.
