Detection and protection assembly for machine tool protective cover

Abstract

The invention relates to a detection and protection assembly for a machine tool protective cover. The detection and protection assembly comprises a light emitting unit, a light receiving unit and a light reflection unit, wherein the light emitting unit, the light receiving unit and the light reflection unit are arranged on the machine tool protective cover according to a certain position and angle, and when light emitted by the light emitting unit is received by the light receiving unit through a set optical path formed by the light reflection unit, the machine tool protective cover is locatedat the set mounting position. According to the detection and protection assembly for the machine tool protective cover, real-time detection and protection of the fixed protection and movable protective attachment state are achieved by arranging an optical detection part on the machine tool protective cover.

Description

technical field [0001] The invention belongs to the technical field of machine tool protection, and in particular relates to a detection and protection component for a machine tool protection cover. Background technique [0002] Machine tool outer protection, as an important functional part of CNC machine tools, has the functions of safety protection, precision maintenance and environmental protection, and is more and more valued by machine tool manufacturers and machine tool users. Generally speaking, many machine tools are equipped with machine tool processing control systems, so the mechanical area is covered by a protective cover to prevent cutting fluid or cutting chips from splashing during processing. The protective cover includes a fixed guard without a movable mechanism and a movable guard with a movable mechanism. Usually, the movable guard is used for the operating part of the processing area. Further, fixed guards can be categorized as "non-removable fixed guard...

AI Technical Summary

Problems solved by technology

However, if the safety lock device is modified so that the machine tool processing control system may be forced to mistakenly believe that the active guard is closed, the machine tool may automatically operate when the active guard is open, resulting in safety problems.

[0003] At the same time, in some cases, such as during machine tool maintenance, the detachable fixed guard is not in the open or closed state like the movable guard, and it is usually designed not to be easily disassembled or disassembled, so its accessories will not be damaged under any circumstances. Machine tool processing control system monitoring, so that even if the maintenance work is completed, the removable fixed guard is not installed or not installed, the machine tool is allowed to operate automatically

In this case, the same safety issues as in the case of active guards being modified safety locking devices may arise
