A sliding table includes a sliding seat having a seat body made from a first material and disposed between two main rigid rails parallel with each other. The seat body has two opposite rail recesses opening toward the main rigid rails, and two inner cyclic track holes disposed between the rail recesses. Two seat body rigid rails made from a second material harder than the first material are fixed in the rail recesses to confront the main rigid rails. Two roller belt modules are arranged in two cyclic track members overmolded to the seat body. When the seat body moves along the main rigid rails, each roller belt module circulates along one of the cyclic track members.

The disclosed technology relates to a moveable panel, such as a fairing, of a vehicle, such as a semi-truck. For a number of reasons, it may be desirable to gain access to the area behind the fairing, for example, to access batteries, air/gas tanks, auxiliary power units, and/or other components that are mounted to the vehicle frame. In order to move the fairing with respect to the vehicle frame, one or more examples of a mounting system are provided that enables the fairing to pivot/swing away from the vehicle frame in a first direction (e.g., forward toward the front wheel). In some embodiments, the fairing may also pivot/swing away from the frame in a second direction (e.g., rearward toward the rear wheels) opposite the first direction. This multiple pivoting/swinging movement of the fairing enables access to different locations behind the fairing.

A workpiece support device includes: a jig, a table, a rotating shaft, a support member, a flow path connector, and a supply-side connecting portion. The jig has a main flow path to flow a fluid for machining and a sub-flow path, and fixes the workpiece. The table has a table flow path to communicate with the main flow path and is attached with the jig. The rotating shaft has a rotating shaft flow path to communicate with the table flow path, and is fixed to the table. The support member rotatably supports the rotating shaft. The flow path connector connects the rotating shaft flow path with a fluid-supply path to communicate with a fluid-supply side so as to relatively rotate with each other about an axis of the rotating shaft. The supply-side connecting portion moves relative to the jig to communicate with and block off the sub-flow path.

A relative displacement specification unit specifies a relative displacement between a jig and a tool.A position determination unit determines whether the jig and the tool are respectively positioned at a jig calibration point and a tool calibration point. A displacement correction unit corrects the measurement values of the displacements of the jig and the tool. A contact determination unit determines whether the tool has come into contact with a workpiece based on a measurement value related to a deflection of the tool. A tool length correction unit corrects tool length data based on the relative displacement when the tool is determined to have come into contact with the workpiece. A control unit generates a control command for controlling the jig or tool based on the relative displacement, a shape of the workpiece, and tool length data indicating a length of the tool.

Disclosed herein in a system for positioning a sub-assembly for installation. The system comprises a tool comprising a base and a sub-assembly support. The sub-assembly support is positioned above the base and pivotably mounted to the base at a pivot axis. The tool is positioned adjacent to an interior surface of an assembling body and configured to support a sub-assembly. The system also comprises at least one actuator that is selectively operable to tilt a first surface of the sub-assembly support toward an opening in the assembling body and adjust an angle of the sub-assembly support, relative to the base. The system further comprises an interior conforming device attached to the tool and configured to interface with the interior surface of the assembling body. The system additionally comprises an exterior conforming device configured to interface with the exterior surface of the assembling body.
