A tram adapter apparatus, kit and method is used with an alignment tool to check the alignment of the spindle and the table of a machine tool. The alignment tool has two or more indicators retained in a spaced apart relation to the spindle of the machine tool. A tram adapter body is interposed between the indicator body and the stop of one of the indicators, moving the indicator tip to a retracted position. The other indicator remains in the deployed position and may be used to tram the table of the machine tool to check the alignment between the table and spindle.

An alignment tool provides for aligning the spindle of a machine tool to a work holding feature of the machine tool. The alignment tool may include one indicator or may include a first indicator and a second indicator in a spaced-apart relation. The faces of the indicators are rotatable. In use, a machinist may attach the indicators to the spindle of a machine tool, advance the spindle or work holding feature until the indicator tips contact the work holding feature. The machinist can rotate the faces so that the machinist can read the indicator faces without placing the machinist's head within the envelope of tool movement of the machine tool.

A positioning device for a machine tool includes a substrate upon which a printing medium is deposited. The substrate has a longitudinal dimension that is longer than the transverse direction of the substrate. The printing medium includes magnetic or magnetizable particles, and the substrate is nonmagnetic. A scale is formed by first regions of the printing medium on the substrate and by second regions without the printing medium between adjacent first regions. The first regions are spaced apart in the longitudinal direction on the substrate. The printing medium is printed within the first regions on the substrate such that the printing medium is thinner in the interior of the first regions and thicker at the edges of the first regions. The location of the positioning device is determined by applying a measuring magnetic field and by detecting a resulting magnetic field emanating from a particular first region on the scale.

A holder system for mounting and aligning a machining device to a rotary transfer machine. The holder system includes a holder with a first part being mountable on a machine or being part of a machine as well as a second part which is releasably coupled to the first part in a defined first position. The second part is coupled to a third part, the third part coupled with the machining device. Positioning features are located between the second part and the third part to allow moving the third part relative to the second part in at least one spatial direction. Further, the holder system includes at least one alignment station that can releasably couple the second part of the holder to the alignment station in the first defined position and a measuring device configured to measure the position of the third part or of the machining device.

An indexing tool for positioning a workpiece, the tool comprising a block having sides, the sides defining a regular polygon. The block has a central opening, and a threaded hole extending at a right angle to the central opening and into and through one of the sides. The block also has a V notch in the block wall opposite the threaded hole, the threaded hole being adapted to have received therein a like threaded set screw.

A representative system includes an alignment tool for aligning attachment interfaces of horizontally-oriented launch vehicle portions. The tool can include a receiver assembly for connecting to a first launch vehicle portion and an actuation assembly for connecting to a second launch vehicle portion. When a first connecting element of the receiver assembly is engaged with a second connecting element of the actuation assembly, the second connecting element can apply force to the receiver assembly, and the actuator assembly applies an opposite force to the second launch vehicle portion, to align fastening features in the launch vehicle portions and/or to reshape the launch vehicle portions. A representative method includes connecting the alignment tool to the launch vehicle portions and operating the tool to apply oppositely-directed forces to align the launch vehicle portions for installing fasteners to connect the launch vehicle portions. One or more bracing beams can connect two tools together.
