The invention relates to a device for detachably securing modules (1), such as tool holders, to a third component (3), such as a rotatable tool disk for a machine tool, including a controllable securing device (51, 53), by which the respective module (1) can be re-secured in a detachable manner in a locked position on the third component (3) by individual securing parts (15). A release device (76, 77) at least partially helps to release the securing device (51, 53) in a release position, such that the release device (76, 77) at least at the beginning of releasing, exerts pressure on the securing device (51, 53) for releasing the individual securing parts (15).

Systems and methods for configuring a power tool. One system includes a power tool communication system that includes an external device and a power tool. The external device includes a user interface configured to receive a first selection to enable a feature of a power tool, and receive a second selection of a threshold of a motor characteristic of the power tool. The power tool includes a motor within a housing. The power tool receives the selected feature and the selected threshold from the external device. The power tool includes a sensor configured to monitor the motor characteristic of the motor. The power tool further includes an electronic processor that controls the motor to operate according to the selected feature and adjusts an operating parameter of the motor when the motor characteristic is determined to cross the selected threshold.

A remote control power tool for a working material including a support configured to support the working material, a power tool fixed to the support, at least one actuator configured to move the working material, a user interface remote from the power tool, a controller communicably coupled to the user interface, video camera proximate the power tool, and a visual display proximate the user interface.

A strut (6) of a circular plug projects upward from a main body (4) of a housing (3) and inserts into circular hole (9) of work (8). An opening (20) is formed laterally in a left portion of peripheral wall (18) of strut (6), a cam portion (28) projects leftward from a right portion of the peripheral wall (18). A positioning rod (22) inserts into insertion hole (14) in upper portion of housing (3) which is movable vertically and radially. A cam surface (32) is provided vertically on upper right portion of positioning rod (22), and pushing portion (33) is provided on upper left portion thereof. When a driving arrangement (D) drives positioning rod (22) downward for locking, cam portion (28) pushes the cam surface (32) leftward, and pushing portion (33) passes through opening (20) to press inner periphery of the circular hole (9) of work (8).

A circumferential positioning device of automobile hub having rotary positioning seat, transition seat, bearing, positioning pin, positioning cylinder, bearing, base frame, main rotating shaft with sliding spline, coupling assembly, link snap-gauge assembly, lead screw, connecting bolt, nut, servo motor, lower bracket of main rotating shaft, small bracket of belt servo motor, belt pulley servo motor, small belt pulley axle, small belt pulley, belt, large belt pulley. The device in the present invention two radial grooves passing through the center that are formed in the bottom surface of the flange of the hub, correspond to the spoke direction on the facade of the hub and are just matched with the two radial bosses passing through the center on the top face of the positioning seat to achieve a positioning purpose.

A machine tool includes a drive unit driving a tool for machining a workpiece, and a control unit controlling the drive unit. The machine tool further includes an abnormality determining unit that determines whether machining can be continued, based on operation information of the drive unit, and a power failure detection unit that switches the power source of the control unit from a normal power supply unit to an emergency power supply unit if power failure is detected, and switches the power source from the emergency power supply unit to the normal power supply unit if recovery of power supply is detected after power failure. The control unit stops operation of the drive unit when power failure is detected, and thereafter, if recovery of power supply is detected, and the abnormality determining unit determines that machining can be continued, the control unit drives the drive unit, thereby automatically resuming machining.

A high pressure coolant tube for receipt by a tool body that includes a coolant tube body with an annular flange adjacent to the exit body end. There is a threaded collar that has an exterior threaded surface. The threaded collar contains an interior collar bore comprising an enlarged diameter interior collar bore surface portion and a reduced diameter interior collar bore surface portion. There is an exit seal pocket defined by an exit-facing flange surface of the annular flange and a reduced diameter body section and the enlarged diameter interior collar bore surface portion. There is an entrance seal assembly pocket defined by an entrance-facing flange surface of the annular flange and a reduced diameter body section and the enlarged diameter interior collar bore surface portion. An exit seal is in the exit seal pocket. An entrance seal assembly is in the entrance seal assembly pocket wherein the entrance seal assembly comprises an entrance seal sandwiched by a pair of thermoplastic polyester elastomeric rings.

A reinstalling method which, when reinstalling an object to be supported, precisely restores the object to an initial installing state in a short period of time without requiring special skills. In a state before supporting of an object to be supported by support tools is released and in each of states in which the supporting is sequentially released, load acting on at least one support tool selected from among the support tools being in a supporting state is obtained. When reinstalling, the object is sequentially supported at the same positions as those before the release by the support tools in the reverse order to that of the release, and, a vertical-direction supporting position of each support tool is adjusted so that a load cell of the selected support tool detects the same value as the load obtained in the supporting state before the support tool was released.

A device for positioning motor vehicle parts in the production or manufacture of motor vehicles. The device includes a main frame, at least one main module configured to be disposed on the main frame, at least one interchangeable first docking plate configured for releasable connection to the main module, and a plurality of first receptacles, arranged on the interchangeable first docking plate, configured to hold the motor vehicle parts at a predefined position during the production.

A machining tool for chip-removing machining includes a tool body and a generator assembly for harvesting electric energy to be used in the tool. At least one first component is secured to the tool body and a second component is movably connected to the tool body so as to, by moving with respect to the first component through interaction therewith, generate electric energy in the first component. The generator assembly includes an arrangement for conducting a medium flow to hit and act upon the second component for moving it with respect to the first component.
