摘要:
A tool turret, in particular provided for the use for a machine tool, has a pivotable tool disk (10), which has on its outer circumference a plurality of receptacles (14) for holders (18) provided with working tools. The holders (18) are attached to the tool disk (10) in a changeable manner by a fixing device (20). Each holder (18) can be swiveled into a working position to permit the assigned working tool to be driven by a drive (22). For this purpose, the working tool can be coupled to an output shaft (16) of the respective holder (18) by a coupling device (26). The fixing device (20) can be actuated by the drive (22) when this drive (22) is uncoupled while stopping the working tool.

A tool turret, in particular intended for use in a machine tool, is for an automated tool change process. In a work station (7) of the pivotable tool disk (5), a holder (9) intended for receiving a machining tool (15) can be attached to the tool disk (5) in a re-detachable manner by a clamping device (31) assigned to the work station (7). In an adjusting position of the tool disk (5) that differs from the working position (11), the respective clamping device (31) can be activated or deactivated, while leaving the holder (9) on the tool disk (5). In a changing position of the tool disk different from the working (11) and adjusting positions (57), the clamping device (31) unlocks the holder (9) in such a way that the holder can be removed from the tool disk (5) and replaced with another holder (9) to be used.

A machining apparatus has a frame, a magazine holding a plurality of tools, a loader capable of moving the tools between the magazine and a primary transfer position, first and second tool holders each displaceable horizontally and vertically on the frame, and a transfer arm carrying a grab. Each of the tool holders can move into and out of a respective secondary transfer position for switching a tool, one of the tools is removed from the magazine with the loader and moved by the loader into the primary transfer position, then the one tool is transferred position to the grab of the transfer arm. This arm is them pivoted to move the one tool in the grab from the primary transfer position into one of the secondary transfer positions, and then the tool at the one secondary transfer position is transferred from the grab to the respective holder.
摘要:
A machine tool comprising a turret for receiving tools, a drum magazine for storing further tools, and an automatic device for conveying the tools from the magazine into a working position on the turret, in which the drum magazine is arranged coaxially to the turret. The tools of the turret may define a pitch circle and the drum magazine may be constructed as part of the turret within the pitch circle or it may be arranged in rotary manner within the said pitch circle. In another construction, the drum magazine has the shape of a circular segment and is arranged outside the turret.

An automatic cutting-tip replacing apparatus in a machine tool, having means for firmly clamping, at the required position, a cutting-tip which is detachably attached to the predetermined position of a tool holder or a cutting tool shunk and for removing the cutting-tip therefrom, and also having means for feeding a spare tip to said required position, said apparatus being mounted on a rotary table rotating between the tipreplacing position and the awaiting position. This arrangement eliminates the prior need of replacing the entire tool holder and greatly reduces the size of the tool replacing device thereby making both the designing of the apparatus and the attachment of the apparatus to the machine easy, providing an efficient operation as well as greatly saving time and labor.

In a machine tool having a tool carrier (1) that comprises at least one receptacle (4) for a tool holder (3) for driven or stationary tools a tool change device is provided that comprises gripping means (370) for gripping the tool holder (3) at the housing (7) or at part (71) connected with the housing (7). In addition to the gripping means the tool change device comprises a device for actuating the fastening means that are configured for attachment of the tool holder at the tool carrier.
摘要:
A machine tool comprising a table on which a spindle holding the workpiece moves in horizontal direction along the workpiece. A tool post is sidewardly movable toward the table. An arbor head is connected to the end of the post and is both axially and circumferentially movable. The arbor head includes a powered arbor for holding and possibly rotating a tool. The result is that the workpiece is movable in one direction and the arbor support is movable in two other orthogonal directions as well as being rotatable. Thereby, a variety of complex machining operations may be performed. A tool magazine and an automatic tool changer are provided.
摘要:
A turning machine (10) having a tool changer (70) capable of automatically changing O.D. and I.D. tools. A tool block system which supports the various tools is utilized. The tool changer (70) has a pair of fingers (74) disposed at the end of a cross arm (72). Fingers (74) are independently movable for engaging O.D. tooling blocks (32) and I.D. tooling blocks (33). Cross arm (72) is indexable to positions for installing the gripped tooling blocks (32,33) onto tool turret (16) or a tool storage magazine (60). A gauge mechanism (80) which pivots a touch probe (82) into the machine tool cutting plane is provided for accurately locating the position of various cutting tools. Offset of the tool cutting point from denominal position is compensated for software of the machine tool controller (22). Probe (82) can also be used in conjunction with another probe supported from turrets (16) for inprocess part gauging.
摘要:
A lathe having a longitudinal slide, a longitudinal guide for said slide, a tool magazine and an automatic tool changer, the tool changer being arranged on the slide and the tool magazine having a number of tool storage holders arranged in rows along the guide.
摘要:
An arrangement for changing tool-supporting tool holders on a machine tool assembly including an installation for clamping the tool holders and moving the tool holders in a linear movement between two clamping positions on a turret and a belt magazine, the tool holder and clamping installation having cooperative groove and plunger means extending at a small acute angle relative to the linear movement so as to prevent interference between the various components during the tool holder changing sequence.
