Provided is an apparatus for detecting a failure in holding a tool of a machine tool that includes, in each of a plurality of tool holding mechanisms in a tool magazine, a locking member provided to have different self-displacement positions for a case where a tool is held at a proper held position between tool gripping portions of a pair of holding arms and a case where the tool is held with deviation from the proper held position, and that detects a holding failure state of the tool in the tool holding mechanism by detecting the position of a detection target portion that moves integrally with the locking member with a predetermined detector provided in the machine tool. The apparatus makes it possible to effectively prevent a risk of a breakdown of and damage to the machine tool.
An apparatus for detecting a failure in holding a tool of a machine tool including a tool magazine that holds a plurality of tools in an attachable/detachable manner, and configured to use one tool of the plurality of tools by selectively and exchangeably attaching the one tool to a machining spindle, the apparatus comprising:
A method for detecting a failure in holding a tool of a machine tool including a tool magazine that holds a plurality of tools in an attachable/detachable manner, and configured to use one tool of the plurality of tools by selectively and exchangeably attaching the one tool to a machining spindle, the tool magazine including a plurality of tool holding mechanisms that hold the tools, each of the tool holding mechanisms including a pair of holding arms that extend from one end side to an other end side and include tool gripping portions provided on the one end side to grip the tool, a pair of supports that are provided at intermediate points of the pair of holding arms in an extending direction, an urging member that is provided between the pair of holding arms at a location adjacent to the other end side of the holding arms and urges the tool gripping portions in a tool gripping direction via the supports, and a locking member that is interposed between the pair of holding arms and provided at a location closer to the other end than a location where the urging member is provided, and is movable between a locking position where the locking member causes the pair of holding arms to continue gripping the tool with the tool gripping portions and a release position where the locking member allows displacement to cause the pair of holding arms to discontinue gripping the tool with the tool gripping portions, the method comprising:
