摘要:
A machining device comprising five axial kinetic coordinate systems that can be controlled simultaneously, three axes of which are linear moving axes and two axes of which are rotary axes, with one axis of the five axes being provided with a tool rotating function, whereby said machining device is equipped with a cutting tool 51 and a friction stir welding tool 52. The current value observed when a large-diameter portion of said tool 52 contacts the work object is set in advance, and by observing the torque current of the rotary shaft of the tool 52 during friction stir welding, the insertion depth of the tool 52 can be controlled by maintaining the observed torque current above the preset current value, thus providing a good weld. A single device can provide both the cutting and the welding. Thus, it is possible to reduce equipment cost, installation space, plant area, lead time and production cost.

The present invention provides a tool changer for removal and installation of tools in a machining center having a spindle for holding a tool including a tool rack having a plurality of locations for holding tools and a rotatable arm movable between the spindle and the plurality of locations. Each of the plurality of locations has a clip for holding a tool and each clip has two arms with the arm on a first side of the clip having an inclined surface. The rotatable arm includes at least two grippers with each gripper defining at least one cam surface, the cam surface being structured and arranged to engage the inclined surface of the clip to allow for the removal of a tool in the clip.

An automatic tool exchanging device for a machine tool, comprising a stopper block (5, 5') attached to a magazine supporting member (2) supporting a magazine (1) at the lower end thereof and capable of swinging to the front and rear, and pulled by an elastic member (8) having one end connected to the upper end of the magazine supporting member (2). Upon arrival of the magazine (1) at a standby position from a tool exchanging position, a stopper (4, 4', 11) is engaged with the stopper block (5, 5') to prevent vibration of the magazine (1). A desired tool among various tools stored in the turret magazine is selected automatically and automatically exchanged for a tool on the machine tool.

The center comprises a conveyor, a motor-driven carriage equipped with a gripper to move a section (2) over the conveyor, along a numerical axis toward the fixed frame (7) of a machining station, and a vise (11).In accordance with the invention, the machining station includes only the following: two moving elements (16, 21) adapted to move along cross-axes, the first said element (16) being movable relative to the fixed frame (7) and the second (21) being movable relative to the first (16), said second moving element (21) carrying a swivelling spindle head (25) equipped with at least one tool (5).Also, the actuator (22) which controls the movement of each said element is a multipurpose actuator selectively controlled by the main numerical control program to execute either positioning-only commands, or feed-only commands, or combined commands, among others.
摘要:
A tool magazine for an automatic machine producing various machining operations with the aid of machine tools held by a machine spindle. The magazine for replaceable tool is adapted to hold a plurality of tools each in tool holding mechanisms being held on a tool pallet mounted on a rotary table of the automatic machine. The spindle cooperates with the magazine so as to be in alignment with a tool holding mechanism of the magazine at a tool replacement position; whereby a new tool can be withdrawn from the tool holding mechanisms by the spindle or a used tool held by the spindle can be inserted into the tool holding mechanism. In addition, the magazine is indexed, to align the several tool holding mechanisms, one at a time, with the spindle at the tool replacement position by transmitting spindle movement, preferably through a tool, to the magazine. The magazine may include a plurality of magazine units, each carrying several tool holding mechanisms on a supporter adapted for rotation about a shaft in response to defined spindle movement. Releasable lock mechanisms prevent non-commanded support rotation.
摘要:
A grinding machine wherein the spindle which supports a grinding wheel during removal of material from a workpiece and/or any one of several carriers for spare or substitute grinding wheels are movable relative to each other to positions in which a grinding wheel can be transferred from a selected carrier directly onto the spindle or vice versa. The carriers are mounted in or on a stationary or mobile magazine and their axes can extend radially of a horizontal axis or radially of a vertical axis. The carriers can form one or more rows or one or more annuli. The magazine can be mounted adjacent to the frame of the grinding machine, on a horizontally reciprocable table which supports a vertically or horizontally movable carriage for the spindle, or at a level above the normal level of the spindle.

The present invention is directed to a gang head for a replaceable gang head type machine tool. The machine tool includes a base, a jig table, a driving member mounted on the base and movable to an advance and retract with respect to the jig table, and an annular rail surrounding the driving member. The annular rail has a rear stationary rail and a movable front rail, the movable rail movable to advance and retract with respect to the jig table along the same direction as the driving member. The gang head comprises a base frame mounted on the movable rail, a working unit mounted on the base frame, wherein the working unit is inclined at an angle other than a right angle, with respect to the direction of advance and retraction of the movable rail, an oil pressure pump, and an oil pressure operated cylinder. The oil pressure cylinder being operatively coupled to the working unit for advancing and retracting the working unit with respect to the jig table.

A tool changer for use in a transfer machine includes a pallet movable to a station in front of a machining unit, and a tool support mounted on the pallet for releasably supporting a tool. The machining unit is movable by an actuator toward the tool support to receive the tool from or release the tool onto the tool support. When the machining unit is advanced toward the tool support, the pallet is lowered by another actuator to release the tool support from supporting the tool, which has been held by the machining unit. Prior to transfer of the tool from the tool support to the machining unit, the tool is held down against the tool support by a clamp arm pivotably mounted on a clamp frame fixedly placed on the pallet. The clamp arm is angularly actuatable to release the tool in response to the movement of the machining unit toward the tool support.
摘要:
A machine tool having a frame, a turret head rotatably mounted upon the frame, at least one tool spindle rotatably supported within the turret head, first coupling means mounted upon the tool spindle, and second coupling means slidably and rotatably mounted within the frame and adapted to engage with the first coupling means of the tool spindle positioned at an operative position so as to transmit a driving power to the tool spindle. Within the turret head there is mounted angular maintenance means for maintaining the tool spindle in a first predetermined angular position. Within the frame there are mounted release means for releasing the tool spindle positioned at the operative position from the angular maintenance means, orienting means for positioning the second coupling means to a second predetermined angular position, and means for moving the second coupling means positioned at the second predetermined angular position into and out of engagement with the first coupling means.
摘要:
A mechanism for interchanging a plurality of non-captive tools between a tool support rack and a work station. An upwardly opening Vee bearing is provided at each work station for supporting a tool at two spaced locations intermediate the ends thereof. The tool support rack includes a pair of horizontally extending rails having aligned tool engaging recesses on the upper surfaces thereof, the rails engaging the tools at two spaced locations intermediate the ends thereof and offset from the Vee bearing support locations. Means are provided for effecting vertical and lateral movement of the support rack to effect tool transfer between the rack and the Vee bearing.
