Abstract

본 발명은 선반의 베드상에 설치되어서 주축의 중심과 동일 중심을 갖는 하우징과 베어링 하우징 및 단동척으로 구성되는 방진구를 제공하되, 하우징은 힌지를 중심으로 개폐되는 상하 반원형상의 일체 조립형이며, 단동척은 베어링으로 지지된채, 베어링 하우징으로 회전 가능하게 설치되면서 전면에는 4개의 소프트 죠우(SOFT JAW)가 갖추어져 있으며, 후면에는 조임봉이 설치되어져서, 선반의 베드상에서 상기 하우징을 왕복대로 중심 맞춘 가공을 완료한 후 베어링 하우징 및 단동척을 설치함에 따라 지그가 필요없게 된다. 따라서 가공시간이 비약적으로 절감됨은 물론이고, 가공된 공작물의 가공률이 높으며, 특히 길이가 긴 공작물인 경우에 본 방진구로써 지지축을 겸하도록 하면 길이 제한없이 공작물을 가공할 수 있는 효과를 얻을 수 있게 되는 것이다.The present invention is provided on the bed of the shelf, provided with a housing having a center and the same center as the center of the main shaft, and a dustproof opening composed of a single-chuck chuck, the housing is an integral assembly type of upper and lower semi-circular shape to open and close around the hinge, The single-acting chuck is rotatably installed as a bearing housing while being supported by a bearing, and has four soft jaws in the front and a tightening rod in the rear, centering the housing on the bed of the shelf as a shuttle. After the machining is completed, the jig is eliminated by installing the bearing housing and the single-acting chuck. Therefore, the machining time can be drastically reduced, and the machining rate of the machined workpiece is high. Particularly, in the case of a long workpiece, when the double shaft is used as the support shaft, the workpiece can be machined without any length limitation. Will be.
