Description
Technical Field
The invention relates to the field of ship steel pipe manufacturing, in particular to a flange bolt hole double-hole positive detection tool.
Background
Generally, when a flange steel pipe is manufactured, a straight pipe is cut and discharged, the cut straight pipe is placed on a support frame on a working platform to enable the pipe to be in a horizontal state, and then the flange is installed.
After the flange is mounted to the pipe orifice, the alignment of two eyes of the flange is detected, and normally, a horizontal ruler is manually held to detect whether the lower edge connecting line of the symmetrical bolt holes is horizontal or not; the two-hole alignment is needed, so that the positions of the bolt holes of the flange after the conversion can be determined according to the standard position of the initial bolt holes and the conversion process when the position of the flange is converted in the follow-up process.
After the symmetrical bolt hole connecting lines are horizontal, a right-angle caliper is used for detecting whether the flanges are perpendicular to the central connecting line (pipe wall end face plain line) of the pipe or not, after the flanges are determined to be perpendicular, a welding gun is used for tack welding and positioning the flanges at one end and the pipe, and after at least 3 points are tack welded on the end faces of a group of flanges, the flanges at the other end are installed.
After the flange nails are welded, 2 persons use the tape measure to detect the length of the pipe in a matching way, and the person in the detection is easy to have deviation when seeing the orthogonal value of the tape measure strip and the flange surface of the pipe.
During the tube manufacturing process, 3 aspects of accuracy are controlled and detected for the tube: 1. whether the bolt holes of each group of flanges meet the requirement of right eyes or not; 2. whether the end faces of the two groups of flanges are perpendicular to the connecting line of the pipe cores or not; 3. whether the length dimension of the tube is in accordance with the design value.
For the first problem, subjective deviation is easy to occur when the level is used for detecting on site, and the level is used for detecting eyes which are dependent on people, so that the eyes cannot be detected without being held by hands, and the operation process is very troublesome.
For the second problem, the end face degree of the flange can be controlled and detected by using a right-angle caliper, but a deviation value cannot be read in detection (only a gap can be visually observed), the measurement precision is insufficient, and the operation convenience is poor;
for the third problem, 2 people are needed for matching detection during size detection, the operation is relatively troublesome, and sight line reading deviation is easy to occur during size detection.
