Abstract

가. 청구범위에 기재된 발명이 속한 기술분야end. The technical field to which the invention described in the claims belongs

서보 리니어 액츄에이터.Servo linear actuator.

나. 발명이 해결하려고 하는 기술적 과제I. The technical problem that the invention is trying to solve

엘엠 가이드의 사용을 배제하고 고정부와 운동부가 간단한 구조로 지지될 수 있는 메커니즘을 제안함과 동시에 리니어 액츄에이터가 가장 일반적인 메커니즘에 사용될 수 있도록 최대 6자유도를 제공할 수 있는 조인트 및 액츄에이터 구조도 동시에 제시코져 하는 것임.It proposes a mechanism that allows the fixed part and the moving part to be supported by a simple structure while eliminating the use of the LM guide, and simultaneously presents a joint and actuator structure that can provide up to 6 degrees of freedom so that the linear actuator can be used for the most common mechanisms. It is to be a nose.

다. 발명의 해결방법의 요지All. Summary of Solution of the Invention

상하단이 유니버설 조인트(4,5)에 연결되고 6자유도를 가지면서 서보 모터(8), 2개의 튜브, 볼 스크류(9)에 의해서 직선운동을 생성하도록 하였으며, 상부 유니버설 조인트(4)에는 오프셋 링크(25)를 적용한 것이다.The upper and lower ends are connected to the universal joints 4 and 5 and have six degrees of freedom, so that linear motion is generated by the servo motor 8, two tubes, and the ball screw 9, and the upper universal joint 4 has an offset link. (25) is applied.
