Claims

[Scope of utility model registration request]

Between a tool magazine that stores multiple types of tools and a machine tool that is equipped with a fixing member that fixes and releases tools from the spindle, there is a tool magazine that extends parallel to the spindle and is rotatable and movable in the axial direction. An exchange shaft is provided, and the longitudinal center of each arm is attached to the front end of the exchange shaft in the axial direction, and each arm is provided with a gripper that is perpendicular to the exchange shaft and can grip a tool at both ends in the longitudinal direction, and the tool is stored in a tool magazine. One gripper grips the tool to be used next, while the used tool to be released from the spindle is gripped by the other gripper, and then both tools, the gripper, the arm, and the entire replacement shaft are moved forward. Then, both tools, the gripper, the arm, and the entire exchange shaft are moved back, and the tool to be used next is transferred from one gripper to the main shaft, and is fixed to the main shaft by the fixing member. , in a machining center in which a used tool is delivered to and returned from the other gripper to a tool magazine, each gripper comprises a pair of gripping claws that can be opened and closed, and a cam that controls the operation of the fixing member. A transmission means is provided which forms a cam surface with which the cam follower engages, and is configured by connecting a plurality of transmission members one after another,
A transmission member disposed at one end of the transmission means is connected to a cam follower, and a transmission member disposed at the other end of the transmission means is connected to a gripping pawl, so that the gripping pawl is closed when a tool is replaced, and the gripping pawl is closed when a tool is on standby. A machining center characterized by having open claws.
