To provide a hand stocker with a simple structure. A hand stocker housing a hand for attaching on an actuator includes a housing board that houses the hand in a hung state and includes a hanging mechanism hanging the hand on a board surface facing the hand. The hanging mechanism includes: a hooking member that extends in a horizontal direction from the board surface to engage with a hanging portion disposed in the hand; a pressing member that prevents the hand hung on the hooking member from moving to a direction separating from the board surface; and a supporting member that restricts the hand hung on the hooking member from moving to a direction approaching the board surface. The hand is sandwiched between the pressing member and the supporting member and housed.

A tool changing system that includes a tool mount adapter and a tool holder. The tool mount adapter is configured to be attached to a tool and selectively engage and disengage a tool bit. The tool provides movement to the engaged tool bit to perform work on a workpiece. The tool holder is positioned in proximity to hold the tool bit when the tool bit is not engaged by the tool. The tool holder can also selectively engage and disengage the tool bit.

A method for machining a workpiece includes using a multi-axis robot to lift a tool head from a magazine. The robot attaches the tool head to an end of a drill tube. The drill tube is then rotated and longitudinally translated to machine the workpiece. The tool head is withdrawn from the machined workpiece longitudinally by moving the drill tube. The robot is used to disconnect the tool head, replace the disconnected tool head into a magazine and withdraw a different tool head from the magazine for attachment to the drill tube.

A system for inserting and removing cutting inserts of a cutting tool includes a first processing device, a second processing device, and a controller coupled to the first processing device and the second processing device, wherein the first processing device includes a gripping element for holding or securing a cutting insert, wherein the second processing device includes a fastening tool for fastening or releasing a fastening mechanism holding the cutting insert, and wherein the control is adapted to control the first processing device to hold the cutting insert, to control the second processing device to fasten or release the fastening mechanism when the cutting insert is held.

The invention relates to a processing plant (1) comprising: at least one first working spindle (2); a tool magazine (6) for storing different processing tools (4), wherein at least one storage plane (10) having several tool receiving spaces (11) arranged next to one another is provided in the tool magazine (6); a tool change device (5) comprising at least one first gripper device (13) for exchanging the processing tool (4) held in the working spindle (2), wherein the gripper device (13) comprises at least one first gripper unit (15) and one second gripper unit (16) which are positioned at a gripper-unit distance (17) from one another. The gripper units (15, 16) can be displaced between the working spindle (2) and the tool magazine (6).

A tool magazine has been developed, in which the tool rack includes a gripper into which the holder for the tool that keeps the cutting part standing and facing upward is to be fitted from above, the gripper has a ring-shaped inner circumferential edge that has an opening in an approaching and leaving direction of the tool moved by the magazine arm, a pair of engagement portions are arranged on opposite ends of the inner circumferential edge and beyond a half turn of a horizontal section of the holder, and the magazine arm includes: a hand configured to grip the holder for the tool that keeps the cutting part standing and facing upward in a horizontal direction; approaching and leaving means configured to cause the hand to approach the gripper and leave therefrom; and elevator means configured to move the hand up and down.

A tool holder locking device has a base, a horizontal support mounted on the base to hold a first tool holder, and a vertical support mounted on the base to vertically hold a second tool holder. The horizontal support has a supporting block having a holding cavity and an engaging rib radially protruding from the holding cavity to engage with a gripper groove of the first tool holder, a first positioning member fixed on the supporting block to engage with a positioning notch of the first tool holder, and a second member fixed on the supporting block to engage with an orientation notch of the first tool holder. The vertical support has a supporting sleeve and a positioning block mounted on a bottom of the supporting sleeve and extending along a radial direction of the supporting sleeve to engage with two driving grooves of the second tool holder.

A welding station includes a welding gun that includes first and second caps. The welding gun is movable between a working position and a maintenance position. The working position corresponds to a welding operation on at least one workpiece. A maintenance tool assembly is configured to cooperate with the first and second caps in the maintenance position. The maintenance tool assembly includes a cap extractor, a cap dispenser and a cap dresser. The cap extractor is configured to remove the first and second caps from the welding gun. The cap dispenser is configured to provide a new cap to the welding gun for installation. The cap dresser is configured to shape the cap face. The maintenance tool assembly includes a lift actuator. A translate actuator is respectively configured to move the maintenance tool assembly in the lift and translate directions with respect to the welding gun.

The invention relates to a clamping device (10) for a tool (18) on a machine tool having a holder block (12) with at least 2, in particular a multiplicity of, apertures (16) for receiving clamping sleeves (14), wherein at least two clamping sleeves (14) are received in the apertures (16). Each clamping sleeve (12) has a clamping element (36), with which a tool (18), in particular a shaft (20) of a tool (18), can be clamped. The clamping sleeve (14) at least partially passes through in each case the aperture (16) in the holder block (12) and has, at its end opposite the clamping element (36), the rear end, an expansion element (34) which engages behind the holder block (12) or a counter-support element (30) of the holder block (12).

A cutting machine includes a holder located below a spindle to hold processing targets, and an adaptor connected to a rotation shaft to rotatably support the holder. The holder includes a first holder fixed to the adaptor and including a pin insertion hole to which a fixing pin attached to a processing target is fixed, and a second holder detachably attached to the first holder and including a pin insertion hole at a position facing the pin insertion hole. The fixing pin extends in a Y-axis direction. In the Y-axis direction, a distance between a processing target fixed to the pin insertion hole and a processing target fixed to the pin insertion hole is shorter than a length of the fixing pin.
