Title (EN) APPARATUS FOR MEASURING DISPLACEMENT OF TAILSTOCK TRANSFER CYLINDER, AND MACHINE TOOL INCLUDING SAME
(FR) APPAREIL POUR MESURER LE DÉPLACEMENT D'UN CYLINDRE DE TRANSFERT DE CONTRE-POUPÉE, ET MACHINE-OUTIL COMPRENANT CELUI-CI
(KO) 심압대 이송용 실린더의 변위 측정 장치 및 이를 갖는 공작 기계
Abstract:
(EN) An apparatus for measuring displacement of a tailstock transfer cylinder comprises: a magnetostrictive wire shaft having a magnetostrictive wire installed to extend through a through hole of a piston within a cylinder bore; a position magnet unit having a permanent magnet movable together with the piston and installed on the piston to surround the magnetostrictive wire; and a position measurement unit for applying a first pulse signal to the magnetostrictive wire, and receiving a second pulse signal which is generated by intersection of first and second magnetic fields formed in the magnetostrictive wire by the first pulse signal and the permanent magnet, so as to calculate the position of the piston.
(FR) La présente invention concerne un appareil pour mesurer le déplacement d'un cylindre de transfert de contre-poupée qui comprend : un arbre de fil magnétostrictif comportant un fil magnétostrictif installé de façon à s'étendre à travers un trou traversant d'un piston à l'intérieur d'un alésage de cylindre; une unité d'aimant de position comportant un aimant permanent mobile conjointement avec le piston et installé sur le piston de façon à entourer le fil magnétostrictif; et une unité de mesure de position pour appliquer un premier signal d'impulsions au fil magnétostrictif, et recevoir un deuxième signal d'impulsions qui est généré par l'intersection de premier et deuxième champs magnétiques formés dans le fil magnétostrictif par le premier signal d'impulsion et l'aimant permanent, de façon à calculer la position du piston.
(KO) 심압대 이송용 실린더의 변위 측정 장치는 실린더 보어 내에서 피스톤의 관통홀을 통과하도록 연장 설치된 자왜선을 갖는 자왜선 샤프트, 상기 피스톤에 상기 자왜선을 둘러싸도록 설치되며 상기 피스톤과 함께 이동 가능한 영구 자석을 갖는 위치 자석부, 및 상기 자왜선에 제1 펄스 신호를 인가하고 상기 제1 펄스 신호 및 상기 영구 자석에 의해 상기 자왜선에 형성되는 제1 및 제2 자기장들이 교차하여 발생하는 제2 펄스 신호를 수신하여 상기 피스톤의 위치를 산출하는 위치 측정부를 포함한다.
