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.

The invention relates to a bending press (1) and/or a loading device (2) for loading a bending press (1) with bending tools (5, 6), comprising: at least one tool holder (3, 4; 13, 14) with a rail (7) having an inner profile (8) for receiving and displacing a bending tool (5, 6), at least one internal wall (9) of the rail (7) forming a guide structure (10) extending in the longitudinal direction of the rail (7); and at least one transfer device (15) drivable by a drive (21) for displacing a bending tool (5, 6) within the tool holder (3, 4; 13, 14) and/or between the tool holder (13, 14) of the loading device (2) and a tool holder (3, 4) of a bending press (1), wherein at least one portion of the transfer device (15) is guided by the guide structure (10) formed in the rail (7).

A tool changer includes at least one tool changer unit, wherein the at least one tool changer unit includes: a tool holder that receives and holds a tool; a base member that supports the tool holder so that the tool holder can be slid along a longitudinal direction of the tool; and a moving mechanism that slides the tool holder relative to the base member.

A hand power tool includes a tool receiver configured to receive a tool. The tool has an outer polygonal coupling and the tool receiver has an inner receiver including, at least portionally, a rotary driver profile. The tool receiver is provided on an associated tool housing, in which there is a drum-type tool change magazine having at least one tool chamber configured to store the tool. The tool chamber is configured to be aligned so as to be flush with the tool receiver to enable the tool to slide from the tool chamber into the inner receiver or from the inner receiver into the tool chamber. An alignment element is configured to align the outer polygonal coupling as the tool slides from the tool chamber into the inner receiver to enable the outer polygonal coupling to slide into the rotary driver profile.

Tool magazine for the provision of tools for a machine tool, wherein the tool magazine has a multiplicity of receiving positions for tools. A first tool can be removed from or inserted into a first receiving position along a removal direction, and at least one further receiving position for receiving a further tool is provided.

A tool changer includes at least one tool changer unit, wherein the at least one tool changer unit includes: a tool holder that receives and holds a tool; a base member that supports the tool holder so that the tool holder can be slid along a longitudinal direction of the tool; and a moving mechanism that slides the tool holder relative to the base member.

This tool exchange device for a machine tool uses an exchange arm to exchange tools between a processing area and a tool accommodation area. In the tool exchange device, an imaging device is used to capture an image of a tool in the tool accommodation area, operation parameters for the exchange arm when the exchange arm is used to exchange the tools are determined from the captured image of the tool, and the exchange arm is operated on the basis of the operation parameters to exchange the tool.

The invention relates to a bending press (1) and/or a loading device (2) for loading a bending press (1) with bending tools (5, 6), comprising: at least one tool holder (3, 4; 13, 14) with a rail (7) having an inner profile (8) for receiving and displacing a bending tool (5, 6), at least one internal wall (9) of the rail (7) forming a guide structure (10) extending in the longitudinal direction of the rail (7); and at least one transfer device (15) drivable by a drive (21) for displacing a bending tool (5, 6) within the tool holder (3, 4; 13, 14) and/or between the tool holder (13, 14) of the loading device (2) and a tool holder (3, 4) of a bending press (1), wherein at least one portion of the transfer device (15) is guided by the guide structure (10) formed in the rail (7).

A tool magazine device includes a rail that is annularly formed and that has a separation section at a part in a circumferential direction of the rail and a holding ring that is arranged coaxially with the rail and that is rotated by a driving motor. The holding ring is provided with a plurality of holding sections that are open in an axial direction of the holding ring. The holding sections are arranged in the circumferential direction of the holding ring. A tool pot is held to be insertable into and extractable from each holding section. A conveyance unit sends out the tool pot placed in the holding section to an exchange position and sends the tool pot into the holding section from the exchange position. A roller supported by each tool pot rolls on the rail in response to the rotation of the holding ring.

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.
