AI Technical Summary
When the existing alignment devices align the bent pipe and the straight pipe, the length of the straight pipe is higher than the height of the crimping ruler, causing the crimping ruler to be unable to fit the top of the straight pipe, and thus fail to align.
A processing and alignment device for welding elbows is designed, using adjustment components, including sliding holes, threaded rods, worm gears and worms. By rotating the handle, the worm, worm gear and threaded rods are driven to rotate, so that the cirrus is moved upward on the inner wall of the sliding hole, and the cirrus height is increased to accommodate straight pipes of different lengths.
It effectively solves the problem of inaccurate alignment due to the length of the straight pipe higher than the height of the crimping ruler, and achieves efficient alignment of straight pipes of different lengths to ensure the accuracy of the welding process.
