Connection；It can be mechanical connection, be also possible to be electrically connected；Can be directly connected, can also indirectly connected through an intermediary,
It can be the connection of two components interiors.For the ordinary skill in the art, on being understood by concrete condition
State the concrete meaning of term in the present invention.
As shown in Figs 1-4, a kind of large-scale circular machined piece measuring device, including shaft 1, rotating arm 2,4 and of rotating seat
Measure plummet 6；The shaft 1 is mounted on one end of the rotating arm 2 and is set to the center of round machined piece 7, the rotation
Seat 4 is mounted on the rotating arm 2 and rotates relative to the center of round machined piece 7, and the measurement plummet 6 is fixed on described
The other end on rotating arm 2 and in the outside wall parallel of round machined piece 7.
When work, shaft 1 is installed on the center of round machined piece 7, and rotating arm 2 is machined by rotating seat 4 in circle
1 rotation around the shaft in the plane of part, when rotating to certain position, measure between plummet 6 and round 7 outer wall of machined piece away from
From measuring and compare respectively by choosing several location points, examine whether the machining accuracy of round machined piece meets public affairs
Difference requires, and is trimmed in time；The error amount of round machined piece 7 can be accurately measured very much using the present apparatus, in time
