Abstract:
The invention relates to a machine tool (1), comprising a plurality of fixed tool spindles (3) and such that can optionally be displaced from a retracted idle position to an extended working position and can be positioned at different positions in a frame-like rack (2), and a workpiece carrier (4) with at least one workpiece holder (5), with the workpiece (4) carrier being movable at least in several axes in a translational manner and preferably also in a rotational manner. In order to provide advantageous constructional conditions it is proposed that at least one of the tool spindles (3) is associated with a tool magazine (7) plus tool changer (8).
Abstract:
A chain-type magazine includes a box, a chain-type conveyor and a spinning unit. The box includes a port defined therein. The chain-type conveyor includes links connected to one another so that each of the links can be pivoted relative to the other links about two axes in parallel to each other. A tool can be inserted in a holder inserted in each of the links. The spinning unit includes a mounting assembly, an elevating assembly, a rotary claw assembly and a connecting rod. The mounting assembly is connected to the box. The elevating assembly is movably connected to the mounting assembly. The rotary claw assembly is rotationally connected to the mounting assembly for catching a selected one of the links. The connecting rod connects the elevating assembly to the rotary claw assembly. The driving element drives the elevating assembly to spin the rotary claw assembly.

Abstract:
The invention relates to a tool changer for changing tools between a spindle and a tool magazine of a machine tool. The object of the invention is to provide a simple and compact tool changer. A plurality of tool pots 19 are detachably held by a circular ring tool magazine 21. Once the tool pot 19 receiving a tool to be changed is positioned at a predetermined position 39, the tool pot 19 is rotated 90 degrees to the inside of the tool magazine 21 so that the axis of the tool to be changed is parallel to the spindle 7. The tools are changed through linear motion and rotational motion of a tool changing arm.
Abstract:
A tool changer drum is rotatably mounted on a machine tool for rotation about an axis which is perpendicular to the spindle axis thereof. A plurality of tool changer arms are swingably mounted on the tool changer drum for swinging movement along radii of the drum between a storage position parallel to the central plane of the drum and a transfer position perpendicular to the central plane of the drum. A pneumatic cylinder is used to index the tool changer drum to place any selected tool changer arm in the ready position. Another pneumatic cylinder is used to swing the ready tool changer arm from its storage position to its transfer position to transfer a toolholder from storage to the spindle and later to swing the tool changer arm back to the storage position to return the toolholder to storage. Before the tool transfer operation, the spindle is moved to a tool transfer position in which the swinging movement of the tool changer arm either places a toolholder in the spindle or removes a toolholder therefrom.
Abstract:
The present disclosure relates to a tool holder to receive and lock a tool taper on a tool magazine, an unlocking device to unlock a tool taper that is received and is locked in a tool holder of this type, and a tool magazine for a machine tool comprising one or more tool holders of this type and an unlocking device of this type.

Abstract:
A chain-type bit-storing apparatus is provided for a CNC machine tool. The chain-type bit-storing apparatus includes a chain engaged with sprockets rotationally provided thereon. The chain includes links each includes a frame, a rotator rotationally connected to the frame, a pin for pivotally connecting the frame thereof to the rotator of another link and a socket connected to the frame and used to receive a bit. There is a pivoting unit for pivoting a selected one of the bits by pivoting a related one of the links.
Abstract:
A machine tool includes a tool magazine for accommodating a plurality of tools, the tool magazine including a tool ejecting section, feeding means for selectively feeding one of the tools accommodated in the tool magazine to the tool ejecting section of the tool magazine, and feed control means for controlling the feeding means so that a feeding speed of the feeding means is set on the basis of a type of a machining operation executed during feed of the tool.
Abstract:
A tool pot is carried by a rotatable pot carrier of a tool magazine to hold a cutting tool with a tail end portion. Swingable between a rest position and an operative position, the tool pot includes a body having an axial tapering bore, an axial end bore for reception of the tail end portion of the cutting tool and a plurality of radial holes each open into the axial end bore at their inner ends. A gripper is provided in the radial holes of the body for releasably gripping the tail end portion of the cutting tool during the time the cutting tool remains held in the tool pot. Built in the body is a tool lock that cooperates with the gripper to lock the cutting tool against removal during the time the tool pot is at the rest position and is caused to swing.
