Embodiment Construction
[0015] See attached picture, before installation of conduit butt joint, as follows figure 1 As shown, it is required that the angle between the conduit axes 2 of the two butt-installed conduits 1 must be within the threshold range, otherwise the installation of the conduits will be deemed unqualified. In actual production, the conduit axis 2 is a virtual position in space, and the angle between the spatial axes of two butt-connected conduits is required to be less than a certain angle. In the process of aircraft development, before the installation of the conduit butt joint, it is necessary to check whether the angle between the conduit axes meets the threshold range to measure.
[0016] The body of the measuring device 4 of the present application is a flat plate structure, the side of the flat plate is the measurement reference, the middle part of the side of the flat plate has an avoidance groove 5, and one side of the avoidance groove 5 is the first measurement reference s...

The invention discloses a device and method for measuring an included angle between butt-joint installation axes of guide pipes. A body of the measuring device is of a flat plate structure, the side edge of the flat plate is a measuring reference, an avoiding groove is formed in the middle of the side edge of the flat plate, one side of the avoiding groove is a first measuring reference edge, and the other side of the avoiding groove is a second measuring reference edge; and an included angle between the first measurement reference edge and the second measurement reference edge is a measurement reference for butt joint installation of the conduit. Mounting joints of the butt-joint conduits on the two sides are placed in the avoiding grooves of the measuring device, the first measuring reference edge of the measuring device is attached to the surface of the conduit on one side, and whether the butt-joint axis included angle between the guide pipes meets the guide pipe butt-joint mounting measuring reference or not is judged according to the attaching state of the surface of the guide pipe on the other side and the second measuring reference edge.
Description
technical field [0001] The present application relates to manufacturing technology, and further relates to conduit installation, in particular to a measuring device and method for measuring the included angle of conduit butt joint installation axes. Background technique [0002] When the aircraft duct is butt-jointed, the product design usually requires that the angle between the axes of the two ducts should be less than one angle before the duct butt joint is connected. The axis of the conduit is a virtual position in space, and there is a requirement that the angle between the spatial axes of the two conduits is less than a certain angle. Before the installation of the conduit butt joint, there is a lack of suitable measuring devices and measurement methods. [0003] At present, there is only an indirect measurement method, that is, by measuring the maximum and minimum values of the end-to-end gap of the butt joint of the conduit and calculating the difference between th...
