A high-speed CNC machine tool safety device

Abstract

The invention relates to a high-speed numerically-controlled machine tool safety device, and relates to the technical field of numerically-controlled machine tools. The high-speed numerically-controlled machine tool safety device comprises a fence plate, a protecting door and a fingerprint recognizing device, wherein a rectangular cavity is formed in the middle of the inside of the fence plate; straight rods are symmetrically arranged on the upper side and the lower side of the rectangular cavity; connecting and starting mechanisms are symmetrically arranged on the upper side and the lower side of the right side wall of the rectangular cavity; an observation window is arranged in the middle of the protecting door; each door body locking mechanism is arranged in the protecting door and positioned between the observation window and the corresponding straight rod; and the fingerprint recognizing device is electrically connected with the door body locking mechanisms. By the high-speed numerically-controlled machine tool safety device, a numerically-controlled machine tool begins to run when the protecting door is closed, the numerically-controlled machine tool automatically stops running when the protecting door is opened, by the fingerprint recognizing device, non-specialized persons can be effectively stopped from opening the protecting door, and potential safety hazards are avoided.

Description

technical field [0001] The invention belongs to the technical field of numerical control machine tools, and in particular relates to a safety device for high-speed numerical control machine tools. Background technique [0002] CNC machine tool is an automatic machine tool equipped with a program control system. The control system can better solve the problem of complex, precise, small batch and multi-variety parts processing. It is a flexible and high-efficiency automatic machine tool.

[0003] Among them, the protective door in the high-speed CNC machine tool is used to ensure the safety settings of the staff. During the processing of parts by the high-speed CNC machine tool, the protective door in the prior art cannot be synchronized with the power mechanism in the CNC machine tool, that is, when the protective door is closed. , the CNC machine tool starts to run, and when the protective door is opened, the CNC machine tool automatically stops running. When some workers are working, the protective door is always open when the high-speed CNC machine tool is running or the protective door is opened when the high-speed CNC machine tool is running, causing potential safety hazards
