Detailed Description
The following will further describe the embodiments of the present invention with reference to the drawings and examples.
As shown in fig. 1-2, a precision connecting flange includes first flange 1 and second flange 2 of matched with, be equipped with the first connecting hole 11 that a plurality of equidistance set up on the terminal surface of first flange 1, be equipped with the second connecting hole 21 with the corresponding setting of first connecting hole 11 on the second flange 2, first connecting hole 11 passes through bolt 7, nut 8 locking with second connecting hole 21, first flange 1 is equipped with constant head tank 3 on the terminal surface with second flange 2 complex, be equipped with elastic component 4 in the constant head tank 3, the position that second flange 2 corresponds constant head tank 3 is equipped with the locating piece 5 that can stretch into in the constant head tank 3 and contradict with elastic component 4, the one end that locating piece 5 and elastic component 4 contradict is equipped with and supports touch block 6, support touch block 6's cross sectional dimension and constant head tank 3 looks adaptation. The alignment between the first flange 1 and the second flange 2 can be realized by the matching between the positioning block 5 on the second flange 2 and the positioning groove 3 on the first flange 1, namely, the positioning block 5 is inserted into the positioning groove 3, so that the first connecting hole 11 and the second connecting hole 21 can be aligned, the positioning effect is generated, the connection between the two flanges is convenient, and the connection of the flanges is more precise; elastic component 4 that sets up in constant head tank 3 is receiving the compression of touch multitouch 6 to take place to warp the back, can produce the elastic deformation power, is used in touch multitouch 6, exerts reverse thrust to touch multitouch 6, on transmitting second flange 2 through locating piece 5, promotes second flange 2 extrusion nut 8, makes the screw thread on nut 8 and the bolt 7 closely cooperate to provide the locking force, avoid nut 8 not hard up, make the connection between the flange more firm.
The quantity of constant head tank 3 sets up two or more, has set up four constant head tanks 3 in this embodiment.
The center of first flange 1 and second flange 2 all is equipped with the passageway that runs through, the passageway diameter of first flange 1 slightly is less than the passageway diameter of second flange 2, be equipped with annular sealed inserted sheet 9 on the first flange 1, sealed inserted sheet 9 stretches into in the passageway of second flange 2 rather than sealing connection, sealed inserted sheet 9 sets up with the passageway an organic whole of first flange 1 for stretching into the other end in the passageway of second flange 2.
