Claims

[Scope of utility model registration request]

The tool has a rotatable main shaft, a main shaft head device which is arranged on a support and is movable in the axial direction of the main shaft, and a gripping means for removably holding a tool, and is set on the axis of the main shaft. An automatic tool changer is provided with a plurality of tool transfer arms that can be selectively indexed to tool exchange positions, and is movable in a direction parallel to the advance/retreat direction of a spindle head device. In a machine tool including a synchronous interlocking mechanism for synchronously moving a tool changer, the automatic tool changer is supported so as to be movable in forward and backward directions on a guide rod that is fixed to a support parallel to the forward and backward direction of the spindle head device. The synchronous interlocking mechanism is spring-biased from both axial sides toward the inner side of the guide rod, and the synchronous interlocking mechanism allows for a limited range of movement towards and away from the automatic tool changer. A trapezoidal dog is disposed on a support body and is biased by a spring in the direction of movement of the spindle head device, and has a flat surface between the front and rear sloped surfaces along the forward and backward direction of the spindle head device, and a trapezoidal dog that is in sliding contact with the dog. It consists of an interlocking piece that is supported by the automatic tool changer and an interlocking roller that can be fitted into the interlocking piece and is disposed on the spindle head device. A release lever capable of forcibly releasing the grasping state of the means is rotatably supported, and a support member is provided with a release lever for abutting the release lever and operating the release lever when synchronized with the spindle head device of the automatic tool changer. A machine tool characterized by a fixed cam plate.
