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-way 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 has reached 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 has reached a predetermined angular position, the operating device is operated to move the tool change arm for removing the tool from the spindle.

摘要： A machine tool includes an indexing device for indexing a spindle to a predetermined angular position for engagement between a key member disposed upon the spindle and a key-way disposed upon a tool to be used. When either the tool, to be used next, upon a tool storage magazine, or a used tool, held upon the spindle, is a tool utilized for heavy cutting, the indexing device is operated before the tool change operation is performed. On the other hand, when the tool to be used next, and the used tool, are both tools utilized for light cutting, the tool change operation is performed without operation of the indexing device.

摘要： A grinding machine provided with an apparatus for changing a feed rate of a grinding wheel relative to a workpiece just before the grinding wheel comes into contact with the workpiece. An electrode device is mounted adjacent to the grinding wheel and connected to an electric power source for applying a potential to the surface of the grinding wheel. A detecting device detects a difference of potential between the grinding wheel and the workpiece to generate an output voltage. A memory device memorizes the output voltage detected when the grinding wheel is distant from the workpiece. A setting device reduces the memorized output voltage at a predetermined rate to provide a reference voltage corresponding to a predetermined gap between the grinding wheel and the workpiece. A comparator circuit compares the output voltage with the reference voltage to generate a feed rate changing signal when the output voltage attains the reference voltage. A control device controls a feed device so as to change the feed rate of a wheel slide in accordance with the feed rate changing signal.

摘要： A torque transmission device is provided wherein a rotary housing is connected to one of front and rear drive shafts which respectively drive front and rear axles of a four-wheel drive vehicle, while a rotary shaft coaxially carried by the rotary housing is connected to the other of the front and rear drive shafts. The housing receives therein a multiple disc clutch device for transmitting rotational power between the housing and the shaft through friction engagement between alternately arranged outer and inner clutch discs which are respectively rotatable bodily with the housing and the shaft. The housing also receives an axially movable piston to press the clutch discs for friction engagement. An end wall of the housing or an end cap secured thereto and a facing end surface of the piston define an axially narrow circuit chamber, within which a rotary with several radially extending blade portions is received to be rotated by the shaft. Several space sections into which the chamber is divided by the rotor blade portions are filled with silicon oil of a high viscosity. When the rotational speed difference occurs between the rotor and the housing, a pressure is generated within each of the space sections thanks to the high viscosity of the silicon oil and is directly applied to the piston, whereby rotational power is transmitted from the housing to the rotary shaft and vice versa.

摘要： A machine tool with an automatic tool change function wherein 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 being selectively inserted within and removed from the tool spindle. When tool changing operation is to be performed, rotation of the spindle is changed to a predetermined speed permitting key-engagement. A first confirming device is provided for confirming the fact that the spindle has reached a first predetermined position during rotation thereof. The tool change arm is then 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 has reached 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 the predetermined key-way of the first and second key-ways.
