Abstract: The present invention has an object to provide a tool replacement system that is capable of preventing the waiting time from occurring as much as possible although an intermediate magazine arranged therefore has a smaller capacity than prior arts. In the tool replacement system, programs pertaining to the sequence of operation and operation time of operating tools 7 are established, wherein, when the operation time of individual tools 7 is shorter than the conveyance time for reciprocation of the tool conveyance apparatus 3 between the tool magazine 1 and the tool replacement arm 4, the object can be solved by realizing transfer of at least a part of the tools planned to be operated in a next process of the corresponding individual tools 7 to the tool replacement arm 4 after the tools are arranged to the intermediate magazine 5.

Abstract: Retractable chuck for drill bits, screw bits and other tools for any chuck size operated by hand or power source which operates without the user touching the bits to move into operating position.

Abstract: An automatic tool changing device (30) has a tool storage device (31) with a plurality of tools stored therein, a tool chucking unit (41) and a tool unchucking unit (51) both capable of advancing/retreating between the tool storage device (31) and a tool changing position (P2), and a tool delivery mechanism (61). The tool chucking unit (41) is provided with a tool fastening mechanism (42) for fastening the tool chucking mechanism (24), and the tool unchucking unit (51) is provided with a tool loosening mechanism (52) for loosening the tool chucking mechanism (24). The tool delivery mechanism (61) delivers the tool positioned at a tool delivery position from the tool storage device into the tool fastening mechanism of the tool chucking unit so that the tool is held by the tool fastening mechanism, and delivers the tool retrieved by the tool unchucking unit from the tool unchucking unit to the tool storage device so that the tool is stored by the tool storage device.

Abstract: A machining center includes a first column, a second column, a crossbeam mounted transversely on the first and the second columns, a tool magazine, an upper tool exchange device mounted on the crossbeam, a lower tool exchange device mounted on the tool magazine and a relay tool exchange device. The tool magazine is mounted near the first column and extends transversely. The relay tool exchange device is mounted on the first column and has a guide device, a frame, a tool case and a driving device. The guide device is mounted on the first column and extends longitudinally. The frame is mounted moveably on the guide device. The tool case is mounted the frame and aligned selectively with the upper and the lower tool exchange devices. The driving device is connected to the frame and drives the frame to approach the upper and the lower tool exchange devices.

Abstract: A machine tool consists in a pair of slide ways set apart one from another and extending parallel with a longitudinal axis, a machining station between the slide ways, presenting a first zone and a second zone adjacent one to the other, and a traveling gantry set in motion along the slide ways and carrying a machining head positionable in the first and second zones. Installed alongside at least one of the slide ways and containing a supply of tools attachable to the machining head is a magazine equipped with a first changer element positioned to coincide with the first zone of the station, and a second changer element positioned to coincide with the second zone, so that whichever of the two zones the machining head happens to occupy at any given moment, the tool currently in use can be replaced with a tool from the magazine by the relative changer element with minimal loss of time.

Abstract: The tools of the various machining heads are housed on a common drum, which is remote from the heads and rotated to select a given row of tools. At each head, there is provided and intermediate station having a container housing a row of tools; and a shuttle provides for sequentially transferring the tools between the drum and the intermediate stations. Each container is rotated 90° between a position cooperating with the shuttle and a position cooperating with a device for exchanging the tools between the head and the container. The container is also movable with respect to the device to select the location of the tool to be changed.

Abstract: In a tool changer system comprising one or more tool grippers together with a pressure foot insert change pod supported on a U-V slide which is independent of the machine work table. The slide services a tool magazine mounted on the machine tool in close proximity to the work table. Because the tool changer is independent of the machine table, the selection and retrieval of the next tool to be used is performed while the machine tool is working in a work cycle. Similarly, the replacement of the used tool back into its storage location is also performed while the machine tool is working. Exchange of the pressure foot insert is also done as part of the tool change process in part during the tool change work cycle. Time is saved because the machine tool work need not be interrupted and the machine tool table need not be moved to accommodate the tool change.

Abstract: A machine tool comprises a spindle having a tool receptacle for receiving tool holders in their working position. A tool changer is provided for conveying a tool holder in a first changing step between a magazine position and a spindle position at said spindle. Further provided is a linear stroke mechanism for conveying said tool holder in a second changing step between said spindle position and said working position. A common drive mechanism is linked to said tool changer and said linear stroke mechanism such as to affect both said first and second changing step.

Abstract: A simple and efficient tool exchanger device is presented. The device has a pair of swing arms (8, 9), and each swing arm is provided with a set of grippers (11, 12) for holding a tool bit. The positions of the swing arms (8, 9) are separated by 90 degree so that they will not interfere with each other during the swinging motion. One driving device (2) is provided to operate both swing arms (8, 9) and operate the gripper devices (11, 12). The swing arm (8) rotates upwards to remove a used tool bit (10) from the machining shaft (21) of a machining center and the other swing arm (9) is rotated downwards to install a new tool bit (10') in the vacated machining shaft in a single simultaneous step.

Abstract: The tool store comprises a prismatic drum having a number of cells in which the tools may be inserted singly or housed inside a magazine; and the tool change device comprises a pair of clamps operated singly and fitted to the work table. The clamps are moved simultaneously in a direction perpendicular to the axis of the drum, for withdrawing or loading the tool from/on to the drum or spindle; the tool being transferred between the drum and spindle by the work table; and a sensor being provided for detecting the tip of the tool inserted in the spindle and so adjusting the axial position of the tool in the spindle.
