摘要： In a machine tool with an automatic tool change function, a rotatable tool spindle carries a key engageable with a key-way formed on a tool. A tool change arm, serving as a tool support device, rotatably supports at least one tool to selectively insert and remove the same into and from said tool spindle. When a tool change operation is to be performed, the rotation of the spindle is changed into a predetermined speed suitable for the key-engagement. An operating device is provided for causing relative movement between the tool change arm and the spindle to insert a tool into the spindle, however, the relative movement thereof is stopped by a stopping device just before the engagement of the key with the key-way. Subsequently, when a first detecting device detects that the key reaches to a predetermined angular position, the relative movement of the tool change arm is permitted to thereby make engagement of the key with the key-way. A second detecting device detects the key-engagement and then the tool is clamped in the spindle for a machining operation. After the machining operation, when a third detecting device detects that the key reaches to a predetermined angular position, the operating device is operated to move the tool change arm for removing the tool from the spindle.

摘要： In a machine tool with an automatic tool change function, a rotatable tool spindle carries a movable key engageable with either of a pair of key-ways formed on a tool. A tool changing arm, serving as a tool support device, friction-rotatably supports at least one tool for selectively inserting and removing the same into and from the tool spindle. When a tool change operation is to be performed, rotation of the spindle is changed into a predetermined speed permitting key-engagement. A first confirming device is provided for confirming that the spindle is reached at a first predetermined position during rotation thereof. The tool change arm is operated to remove the tool from the spindle in response to the first confirming device. A second confirming device is provided for confirming that the spindle is reached at a second predetermined position during rotation thereof. Prior to insertion of the tool into the spindle, the movable key is withdrawn, and in response to the second confirming device the movable key is moved outwardly into engagement with predetermined one of the key-ways.

摘要： A torque transmission device (30) is provided wherein a rotary housing (32) is connected to one of front (12) and rear drive shafts (20) which respectively drive front and rear axles of a four-wheel drive vehicle, while a rotary shaft (20) coaxially carried by the rotary housing (32) is connected to the other of the front and rear drive shafts (12,20). The housing receives therein a multiple disc clutch device (40) for transmitting rotational power between the housing (32) and the shaft through friction engagement between alternately arranged outer and inner clutch discs (37,38) which are respectively rotatable bodily with the housing (32) and the shaft. The housing also receives an axially movable piston (36) to press the clutch discs (37,38) for friction engagement. An end wall of the housing (32) or an end cap (31) secured thereto and a facing end surface of the piston (36) define an axially narrow circular chamber, within which a rotor (41) with several radially extending blade portions is received to be rotated by the shaft. A several space sections into which the chamber (42) is divided by the rotor blade portions are filled with silicon oil of a high viscosity.

摘要： In a machine tool with an automatic tool change function, a rotatable tool spindle (11) carries a movable key (65) engageable with a key-way (18) formed on tool (T). A tool changing arm (13), serving as a tool support device, friction-rotatably supports at least one tool (T) for selectively inserting and removing same into and from the tool spindle (11). When a tool change operation is to be performed, rotation of the spindle (11) is changed into a predetermined speed permitting key-engagement. A detecting device is provided for detecting movement of the movable key (65) to confirm engagement of the movable key (65) with the key-way (18) of the tool (T). A clamp device (21-23) clamps the tool (T) inserted into the spindle (11) in response to the detecting device. After the tool (T) is clamped on the spindle (11), rotation of the spindle (11) is changed into a machining speed. A confirming device (33, 34) is provided for confirming that the spindle (11) is reached at a predetermined angular position during rotation thereof. The tool change arm (13) is operated to remove the tool (T) from the spindle (11) in response to the confirming device (33, 34).
