    摘要: A machine tool comprising a spindle head, a tool magazine, and an arm, the arm being secured to the spindle head, the arm having gripping members for holding a tool holder. When a workpiece is machined, the arm in which gripping members are opened is placed near the spindle. As soon as machining is completed, the grip members are closed so as to hold the tool holder set into the spindle. The end face of the spindle and the end face of the tool magazine stand at different levels when the spindle head is located in tool changing position. When a used tool is returned to the tool magazine, the arm operates in the following steps: first, the arm grips the used tool set into the spindle; second, the arm is moved so as to draw the tool from the spindle; and third, the arm is swiveled so as to return the tool to the tool magazine.

    摘要: A pallet changer includes at least one pallet (4, 14) for holding a workpiece (5, 15); a first guide (41) for guiding the pallet (4, 14); a first support (2) for supporting the first guide (41); a second guide (51) for guiding the pallet (4, 14); a second support (30) for supporting the second guide (51); a first linear motor (40) associated with the first guide (41); a second linear motor (50) associated with the second guide (51). The pallet (4, 14) is made of conductive material so as to serve as a secondary conductor for the first linear motor (40) and the second linear motor (50) for performing changing of the pallet (4, 14) between the first linear motor (40) and the second linear motor (50) along a desired direction (Y).

    摘要: This invention relates to an apparatus and method for sensing a thrust load applied to a spindle of a machine tool. The object of the invention is to generate a signal representing the thrust load alone, exclusive of other forces such as frictional resistance within the spindlehead feeder, etc. so as to accurately measure the thrust load. According, to one disclosed embodiment, a first pressure sensor is arranged between a thrust bearing supporting the spindle and a surface on the spindle support and a second pressure sensor is arranged between a second surface on the spindle support and the machine tool frame. Each of the pressure sensors may be, for example, a piezo-electric film pressure sensor.

    摘要: An automatic tool changing device comprises the head of a machining center and a drum vertically movably mounted on the outer end of the head, and rotatably arranged around a center shaft which is projected from the central portion of the drum to slant downwardly are a large number of arms each having an arbor holding portion at the forward end and formed in a predetermined position on the central back surface with an elongated groove adapted for engagement with a geneva drive pin, whereby when one of the arms is engaged with a main shaft or spindle in the head, the remaining arms are continuously arranged on each side of the engaged arm above a position spaced by a predetermined angle therefrom. Disposed on the back side of the arm engaged with the main shaft and the adjacent arms on both sides thereof is a pair of genevas each having the arm moving drive pin selectively engageable with the elongated groove of the adjacent pair of arms, and every rotation or every plurality of rotations of the genevas in the counterclockwise or clockwise direction moves the arms each by an amount corresponding to one arm or a plurality of the arms.
