The position-returning element enables the tool arm to rotate for upward and downward moving between a first position and a second position. The gripping element functions to grip a main-axle tool or a magazine tool. The tool change unit is combinable with a power unit to form a tool change device. The power unit drives the tool change unit to do rotation or rotation and upward and downward movement.

A machine tool is provided with two vertically oriented tool spindles that are arranged to hold tools and that are movable vertically in a first direction and horizontally in a second direction orthogonal to the first direction. Furthermore, the machine tool is provided with two workpiece support devices for clamping workpieces in place. At least one of the two workpiece support devices is movable horizontally in a third direction orthogonal to the first and the second direction. The two tool spindles and the two workpiece support devices are mounted on a common machine frame with a common working space, wherein the two tool spindles are movable parallel to one another in the second direction. The two tool spindles are facing one another.

The CNC machining device 1 includes a tool magazine 20, a spindle 26, an automatic tool replacing device, a CNC controller 32, a sensor head 10 configured to generate measurement data corresponding to a distance from a surface of the object, and a personal computer 40. The sensor head 10 generates measurement data (X, Z) at regular intervals. The CNC controller 32 generates position coordinate data (x, y, z, xθ, yθ, zθ) at regular intervals. The sensor head 10 transmits the measurement data to the personal computer 40 through first radio communication RC1. The sensor head 10 transmits a synchronization signal for synchronizing the measurement data and the position coordinate data to the CNC controller 32 through second radio communication RC2.

A method for setting up an apparatus (100) which is formed for machining a workpiece with a tool (20) comprises: providing the tool (20) in the region of the apparatus (100), providing a line assembly (53) in the region of the apparatus (100), which is fitted with at least one outlet nozzle, transferring a first linear axis (A1) of the apparatus (100) to a changing position by moving at least one axis of the apparatus (100), receiving the tool (20) by a tool spindle (21) which is carried by the first linear axis (A1), and the line assembly (53) plus the at least one outlet nozzle by a clamping system which is carried directly or indirectly by the first linear axis (A1), or by an additional axis, wherein the receiving of the tool (20) and the receiving of the line assembly (53) occur successively or simultaneously.

Provided is a three-dimensional measurement device applicable to a machining machine. A sensor head contains a body and a collet chuck. A light emitting window and a light receiving window are provided on the front end of the body. A non-contact sensor is incorporated in the body. Laser light emitted by the non-contact sensor is radiated onto a workpiece through the light emitting window. Laser light reflected from the surface of the workpiece is received by the light receiving window. A collet chuck is attached to the rear end of the body. The collet chuck has the same shape as a collet chuck provided by each tool housed in a tool magazine of a machining center.

A system, method, and apparatus for changing a set of old tools for a set of new tools may be presented. The system may comprise a crawler robot, a robotic arm, a tool changer, a vision system, and at least one of a tool rack or a storage area. The tool changer may be an end effector of the robotic arm. The tool changer may comprise a number of grippers and a number of movement assemblies. The number of grippers may perform at least one of moving a set of new tools to the crawler robot or removing the set of old tools from the crawler robot. The number of movement assemblies may be associated with the number of grippers. The vision system may be associated with at least one of the robotic arm and the tool changer.

A processing apparatus includes a holder configured to hold a processing target object; a processing mechanism to which a processing tool configured to process the processing target object held by the holder is installed in a replaceable manner; and an exterior cover accommodating the holder and the processing mechanism therein. The exterior cover includes an entrance opening through which a replacing apparatus configured to replace the processing tool passes when advancing to an inside of the exterior cover from an outside thereof. The processing apparatus further includes a shutter configured to open or close the entrance opening of the exterior cover.

A power tool, comprising: a housing; a motor being disposed in the housing for outputting rotary power; an output shaft having an accommodating hole in the axial direction for holding a tool bit; a transmission mechanism, being disposed between the motor and the output shaft for transmitting rotary power from the motor to the output shaft; a tool bit supporting being disposed in the housing and including several chambers disposed in parallel for holding the tool bit; a connecting member being disposed in the housing and capable of moving axially between a working position where the connecting member passes through one of the chambers and to accommodate the tool bit in the chamber connect the output shaft, and a release position where the connecting member exits and separates from one of the several chambers; and an operating member is arranged on the housing for controlling the axial movement of the connecting member; the power tool further includes an automatic shifting means for adjusting the position of the tool bit supporting in response to the movement of the operating member, wherein the connecting member moves axially to a position that is separated from one of the several chambers, and the cartridge moves to a position where another chamber is axially corresponding to the output shaft under the action of the automatic shifting means.

An apparatus and a system comprise a collet comprising a top portion and a bottom portion. The top portion comprises a threading means. The bottom portion at least comprises means for holding the collet from rotating and means for retaining an end mill. A master comprises a top portion and a bottom portion. The top portion is configured for engagement with a spindle of a milling machine. The bottom portion comprises a threading means for engagement with the threading means of the collet, wherein the master is retained by the spindle and the collet engages and disengages the master by rotation of the spindle. The milling machine operates under computer control during engagement and disengagement of the collet from the master.
