Abstract
The invention discloses a method for detecting coaxiality of cylindrical surfaces with large diameter, which is a center location method applicable to detecting holes and shafts with large diameters and overcoming the limitation of current tripod centering frame detection; the difficulty of coaxial detection on the holes and the shafts with diameter of 700 mm is effectively solved, the coaxial detection is ensured to be accurate and reliable, the operation is convenient, and the location accuracy is high. The detection is performed by sine tripod centering frames composed of installation target holes on a measurement frame, coincidence levels and measuring sticks. The method comprises the steps of: respectively placing the sine tripod centering frame A and the tripod centering frame B on the internal circle surfaces of two holes on a hollow shaft of a mill; aiming at the centers of installation target holes of the sine tripod centering frames A and B by microalignment telescope, and reading deviation XA, YA, XB and YB in horizontal and vertical directions relating to an optical axis; and thereby detecting the coaxial error of the holes on the hollow shaft of the mill: f =(X2+Y2)1/2.

Description
Technical field
The present invention relates to a kind of right alignment detection method, especially a kind of right alignment detects the method for large diameter cylindrical surface.
Background technology
At present, right alignment generally is divided into the right alignment in hole and the right alignment of axle.Right alignment for the hole of large scale engineering goods detects, and in the practice all is to adopt optical means, uses tripod centering frame to confirm the center in hole, reads the deviation of center, hole relative datum axis with micr-alignment telescope.But tripod centering frame can only be used for diameter in the location of 228mm to the hole between the 528mm.Detect for the right alignment of diameter, does not still have at present accurately, reliable method greater than large scale engineering goods such as the hole of 528mm or axles.
In view of the foregoing, the method that detects for the right alignment in the hole of large scale engineering goods needs to improve.

The present invention is in order to realize above-mentioned purpose; Adopt following technical scheme: a kind of right alignment detects the method for large diameter cylindrical surface; Be that the sine centering frame that installation targets hole, combined diagram level, the measurement rod of use device on measurement bay formed detects, concrete steps in sequence is following:
Earlier sine is felt relieved frame A and sinusoidal centering frame B is placed on respectively on the inner headed face in two holes of mill trunnion, and the sine frame A that feels relieved is placed the A1 place; Sinusoidal centering frame B places the B1 place; With their positions in a circumferential direction of skin hammer fine setting, make the combined diagram level on sinusoidal centering frame A and the sinusoidal centering frame B all be in zero-bit; On 4 degree of freedom, adjust micr-alignment telescope, make its optical axis through the center of sinusoidal centering frame A with the installation targets hole 1 of sinusoidal centering frame B; At this moment, the optical axis of micr-alignment telescope is exactly a datum axis;
Again sine centering frame A and sinusoidal centering frame B are moved to position A2 and position B2 place respectively; Make its combined diagram level all be in zero-bit once more; Through the center of the sinusoidal centering of micr-alignment telescope aiming frame A, read their relative optical axis deviation X in the horizontal and vertical directions with the installation targets hole of sinusoidal centering frame B
