Abstract
The utility model relates to detection equipment, in particular to a harness cross type safety grating detection device used on a numerical control machine tool. The detection device comprises a harness transmitting module and a harness receiving module, wherein the harness transmitting module is provided with a plurality of harness transmitting sources, and the harness receiving module is in signal connection with the numerical control machine tool and provided with a plurality of harness receiving ends; if any harness receiving end can receive the harness signal of any harness transmitting source, the machine tool runs normally; and if any harness receiving end fails to receive the harness signal of any harness transmitting source, the harness receiving module outputs a signal to the machine tool to lead the machine tool to stop running. In the safety grating detection device used on the numerical control machine tool, the light rays are used for cross-scanning. Compared with the common protection grating that is used for transmitting and receiving at equidistant intervals, the harness cross type safety grating detection device remarkably reduces the blind areas of the light rays, thereby more effectively protecting the safety of a machine tool operator and the stable operation of the machine tool.
