Claims

[Scope of utility model registration request]

In an apparatus in which a rotating frame is pivotally supported on a machine frame and the rotating frame is index-rotated by a rotary actuator provided on the machine frame, the rotating axis of the rotating frame is set as the X axis, and the rotating frame is A positioning member is provided that is rotatably engaged with the positioning member so as to be movable back and forth in the X-axis direction, and a plurality of index grooves are formed at a predetermined pitch in the circumferential direction on the opposing surface of the machine frame that faces the positioning member in the X-axis direction. , a protrusion that can be engaged with the index groove is formed on the positioning member, the positioning member is biased forward in the X-axis direction by a spring so that the protrusion engages with the index groove; A cam holder is connected to the output shaft of the rotary actuator via a one-way clutch, and the cam holder is engaged with a cam groove formed in the positioning member, so that relative rotation of the cam holder with respect to the positioning member causes the positioning member to be moved by the spring. A cam is installed to move the cam back against the spring, and a lock pin is provided to unrotatably lock the cam holder against the output shaft of the rotary actuator. An indexing device characterized by forming a cam surface that moves the indexing device toward the lock side.
