Abstract

본 발명은 구멍가공기의 공구파손 감지장치를 개시한다.The present invention discloses a tool breakage detection device of a hole machine.

본 발명은, 분할테이블의 선회 위치를 기준으로하여 공구대의 후방과 인접된 베이스상에 고정 설치되는 베이스 플레이트와; 베이스 플레이트로 부터 상부를 향해 연장 형성되는 지지축과; 지지축의 상부에 고정 설치되는 고정 플레이트와, 주축대의 가공물과 대면하도록 위치되며, 공구대의 공구에 의해 가공된 가공물상의 구멍 가공여부를 감지하는 감지부와; 감지부와 고정 플레이트 사이에 개재되어, 감지부를 주축대의 가공물을 향하여 왕복 이송시키는 가이드부;를 포함하여 된 것으로서, 공구의 파손여부를 즉시 감지함으로써, 가공물의 가공불량을 최소화 할 수 있는 이점이 있다. 따라서 작업성 및 생산성의 향상을 꾀한 효과가 있다.The present invention includes a base plate fixedly installed on a base adjacent to the rear of the tool base on the basis of the pivot position of the partition table; A support shaft extending upwardly from the base plate; A fixing plate fixedly installed at an upper portion of the support shaft, and a sensing unit positioned to face a workpiece of the spindle shaft and detecting whether a hole is formed on the workpiece processed by the tool of the tool holder; Interposed between the sensing unit and the fixed plate, the guide unit for reciprocating the sensing unit toward the workpiece of the main shaft; including, as soon as detecting the damage of the tool, there is an advantage that can minimize the processing defect of the workpiece . Therefore, there is an effect to improve the workability and productivity.
