Automatic protection door for built-in tool magazine

Abstract

The invention provides an automatic protection door for a built-in tool magazine, and relates to the technical field of numerical control machine tools. The automatic protection door for the built-in tool magazine comprises the built-in tool magazine, a protection plate and a tool changing opening are arranged on the front wall of the built-in tool magazine, the protection plate is fixedly connected to the front wall of the built-in tool magazine and is close to the top, the tool changing opening is formed in the front wall of the built-in tool magazine and is located on the lower side of the protection plate, a first sensing device is arranged on the inner side of the tool changing opening, the front wall of the protection plate is fixedly connected with a lamp holder, and the front wall of the lamp holder is fixedly connected with an alarm lamp. According to the automatic protection door, a door opening triggering device is arranged, so that the situation of mistaken opening is avoided; a bearing slides in a sliding groove in a sliding rail, so that the overall operation action is smooth and unobstructed; when the machine tool breaks down, the next action can be automatically stopped through the first sensing device, a second sensing device and a testing assembly, and accidents such as machine collision and the like are avoided; an auxiliary closing assembly is matched with a sealing gasket, and it is guaranteed that the sealing performance is better when the automatic door covers the tool changing opening.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to an automatic protective door for a built-in tool magazine. Background technique [0002] The tool magazine is one of the key functional components for the normal operation of the machining center. Its function is to provide a tool storage position, fast automatic tool selection, and tool change, so that the machining center can complete multiple processes or even all processes in one clamping. In many traditional machine tools, some are equipped with a tool magazine door, while others are not. The tool magazine door is the most important part of the tool magazine protection. It needs to be opened automatically when the spindle tool is changed, and it will be automatically closed after the tool change. After closing, it can be activated. To prevent dust, water and chips, most of the current common tool magazine doors use angled guide rails. When the tool ma...
