Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, and particularly relates to a cantilever tooling for fitting a low-temperature double-layer pressure vessel. Background Art

[0002] In the manufacturing process of a low-temperature double-layer pressure vessel, the fitting operation is one of the key links, and there are often many deficiencies in traditional fitting methods.

[0003] Traditional fitting tooling performs poorly in terms of adjustment accuracy. Due to the lack of an adjustment mechanism, it is difficult to adjust the position of the working block, resulting in difficulty in ensuring the accuracy of the fitting of the double-layer pressure vessel and affecting product quality. At the same time, it is difficult for traditional tooling to ensure the levelness of each component. Because there is no hydraulic system to adjust the deflection of the cantilever body, it is difficult to keep the inner cylinder, the cantilever body and the turning frame of the double-layer pressure vessel approximately horizontal, which will increase the difficulty of fitting and reduce the quality and efficiency of fitting.

[0020] The outer wall of the locking bolt 10 is threadedly connected to the inner wall of the inner cylinder 6, the bottom of the ear seat 5 is fixedly connected to the top of the side plates 4, and the top of the hydraulic system 11 is rotatably connected to the outer wall of the inner cylinder 6. Use a hoisting device to lift the inner cylinder 6, pass the two groups of ear seats 5 through the rotating shafts on both sides of the inner cylinder 6, and then firmly fix the ear seats 5 on the side plates 4, so that the inner cylinder 6 can rotate freely on the turnover rack, providing convenience for subsequent operations.

[0021] On the outer wall of the cantilever body 7, a left - right adjustment motor 12 is fixedly connected through a frame.

[0022] Working principle:

[0023] During use, first assemble the turnover frame. Just place two groups of support pipe fittings 1 parallel to each other, then place the connecting bar 3 between the two groups of support pipe fittings 1 and weld the two ends of the connecting bar 3 to the support pipe fittings 1.
