Title:
工作機械における保護窓へのレーザ光検知センサの取付構造
Document Type and Number:
Japanese Patent JP7146570
Kind Code:
B2
Abstract:
To make it possible that the operation of a laser light detection sensor can be checked with an operation check sensor attached to a protective window even if the protective window has no test light propagation space inside.SOLUTION: Provided is a structure for mounting a laser light detection sensor 1, which comprises an operation check tester 10 having a light emission portion 11 for test light, onto a protective window 20 on a cover of a machine tool, in which a spacer 6 is interposed between the protective window 20 and the laser light detection sensor 1. Inside the spacer 6 is formed a propagation space S which allows test light L from the light emission portion 11 of the operation check tester 10 to reach a light-receiving portion 2 of the laser light detection sensor 1 when the spacer is between the protective window 20 and the laser light detection sensor 1.SELECTED DRAWING: Figure 1
