摘要： In a tilting table indexing device driven by a direct-drive motor, a tilting table is prevented from rotating beyond an allowable rotation range when power is shut off in an emergency, such as power outage, and thus a breakage accident of, for example, a tool or a workpiece is reliably prevented from occurring. In a tilting table indexing device (1), in which a rotary member (3) such as a table (4) is rotated within a predetermined normal rotation angle range by a direct-drive motor (9) to tilt the table (4) and in which the tilted table (4) is held by activation of a holding mechanism (10), an elastically displaceable member (11) having a pressure receiving surface (12) is provided at one of the rotary member (3) and a frame (6) of the tilting table indexing device (1), and an engaging portion (13) capable of contacting the pressure receiving surface (12) is provided at the other of the rotary member (3) and the frame (6). When the rotary shaft (5) rotates beyond the normal rotation angle range because of free rotation of the rotary member (3) in an emergency, the elastically displaceable member (11) absorbs the kinetic energy of the rotary member (3) and stops the rotary member (3) before a danger angle range.

摘要： A method of controlling drive of a driving motor for a rotary indexing device is provided. The device includes an indexing mechanism that indexes an angular position of a circular table by rotating the circular table with the use of the driving motor as a driving source, a clamping mechanism that holds the indexed angular position, and a control unit that controls drive of the driving motor by position control. In the method, the control unit controls the drive of the driving motor during operation of the clamping mechanism with a content of control in which an output torque of the driving motor by the position control becomes smaller than an output torque by the position control during indexing of the angular position of the circular table for an equivalent positional deviation.

摘要： A table plate has a coolant channel including at least a pipe that is in contact with at least one of a back surface and an outer peripheral surface of the table plate or a path disposed in the table plate. At least a portion of the coolant channel is in areas outside a reference hole, which is formed in the table plate coaxially with the rotating shaft, the areas corresponding to two or more of four quadrants, which are defined by two perpendicular lines intersecting at an axial center of the rotating shaft in a plan view. The coolant channel has inlet and outlet ends that open in the outer peripheral surface of the table plate or an outer peripheral surface of the rotating shaft. The inlet and outlet ends are respectively connected to a coolant-supplying path and a coolant-collecting path through a rotary joint.
