    摘要： The present invention relates to a tool changer mechanism operative to effect a bodily interchange of a pair of toolholders respectively mounted in spaced apart parallelism in an operating station and a storage station. To effect a tool interchange, a pair of independent and oppositely rotatable toolholder arms, are normally positioned in a vertical or substantially parallel parked position about a common parallel axis, between the horizontally spaced apart operating and storage stations respectively. Each of the toolholder arms is provided towards its opposite ends with inwardly or oppositely disposed semicircular openings movable toward one another into opposed or clamped tool encompassing relationship. The arms are interconnected to be controlled by a novel reversing mechanism to effect clockwise rotation of one arm simultaneously with effecting counterclockwise rotation of the other arm. By means of this arrangement, the inner and outer arms are initially rotated 90* in opposite directions to move the semicircular openings toward one another into a fully enclosed clamped position about the spaced apart toolholders carried in spaced apart parallelism in the operating station and storage station respectively. After urging the separate arms into fully enclosed gripping engagement with the spaced apart tools, a transverse cylinder is actuated to simultaneously move both oppositely clamped arms rectilinearly outward to extract the fully enclosed or clamped tools from the respective sockets. Next, with both arms still locked in enclosed tool engaging position, the entire assembly is rotated 180* to bodily interchange the positions of the enclosed tools relative to the spaced apart storage and operating stations. The assembly is then reversibly moved rectilineally inward to reinsert the now interchanged tools after which the reverse mechanism is again operated to reactuate the arms in independent reversed direction to return parked position.

    摘要： An apparatus to eliminate the stalling of a machine tool spindle electric drive motor when a cutting tool secured in the spindle encounters a hard spot in a workpiece. A current relay is connected in the spindle motor circuit and is energized upon the occurrence of an abnormal load on the spindle motor. A normally closed contact of the relay is located in the feed axis drive system and effects the interruption of the command pulses to the feed axis drive system.

    摘要： This invention relates to an extremely accurate measuring system comprising a single laser interferometer and associated single counting apparatus responsive to a multiple axis laser beam reflectively connected to measure one of a plurality of different movements in a multiple axis machine tool. Preferably, the measuring apparatus is incorporated in a machine tool having a frame provided with a worktable movable along an X axis relative to an upright column mounted on the frame for transverse movement along a Z axis. The upright is disposed to carry a spindle head for movement along a vertical or Y axis to effect selective movement of a cutter relative to an associated workpiece mounted on the worktable in the usual manner.

    摘要： This invention relates to a greatly simplified tool storage and changing mechanism for a machine tool. To accomplish this, a plurality of cutting tools are disposed in a radial array relative to a tool receiving operator. Each tool is carried at the outer end of a single pivotal support with each respective support being individually pivotal to insert a tool carried thereby into the tool operator. After insertion by a single movement of its associated support, securing means are actuated to releasably secure the inserted tool to the operator for performing a desired machining operation. The inserted tool can be returned to a parked or storage position by simply releasing the securing means and pivoting the associated tool support outwardly for returning the tool carried thereby to stored position. In other words, each tool support is pivotal in one direction for inserting a tool into the operator, and is pivotal in open direction for inserting a tool into the operator, and is pivotal in the opposite direction for returning that tool to a radially disposed storage position.
