[0052] When the two outer positioning plates 21 in the lower positioning assembly and the upper positioning assembly are butted, the arc surfaces inside the two outer positioning plates 21 form a circumferential surface, the two guide grooves 23 form a circular groove in abutment, and the two inner positioning plates 25 form a ring clamped on the surface of the split cylinder 100 in abutment. When the inner positioning plate 25 is driven to rotate in the guide groove 23 by the driving assembly, the ring is caused to rotate and slide in the circular groove, so that the split cylinder 100 is rotated and adjusted by the ring, and the inner positioning plate 25 drives the roller 24 to rotate, so that the roller 24 rolls on the inner positioning plate 25 to reduce the frictional resistance when the inner positioning plate 25 rotates.

[0053] As shown in Figure 1 , Figure 2 , Figure 5 , Figure 6 In one embodiment, the driving assembly includes a rotating strip 26, a connecting rod 27, a handle 28, and a connecting shaft 29. The rotating strip 26 and the handle 28 are both arc-shaped structures.

[0057] Please refer to Figures 1-9 As shown, in one embodiment, the locking assembly includes a plurality of push-pull rods 34, a plurality of dynamic friction plates 35, and a plurality of static friction plates 36, the plurality of static friction plates 36 are fixedly installed at one end of the plurality of rollers 24, the plurality of push-pull rods 34 are slidingly inserted into one side of the outer positioning plate 21 and are opposite to the end of the roller 24, the inner side end of the push-pull rod 34 is fixedly installed with the dynamic friction plate 35 abutting the static friction plate 36, and the outer side end of the push-pull rod 34 is in communication with the unlocking assembly; the unlocking assembly includes a strip plate 31 and a plurality of springs 37, the strip plate 31 is in an arc structure and is arranged on one side of the outer end of the outer positioning plate 21, the outer side end of the plurality of push-pull rods 34 is fixedly connected to the inner side surface of the strip plate 31, and the plurality of springs 37 are respectively sleeved on the plurality of push-pull rods 34 and abut against the outer end surface of the outer positioning plate 21 at one end and abut against the inner side surface of the strip plate 31 at the other end; the limiting assembly includes a plurality of adjusting blocks 32 and a plurality of limiting blocks 33, the plurality of adjusting blocks 32 are circumferentially equidistantly distributed and fixedly installed on the outer side surface of the strip plate 31, and the plurality of limiting blocks 33 are circumferentially equidistantly distributed and fixedly installed on the inner side surface of the handle 28, the adjusting block 32 and the limiting block 33 can abut against each other when moving in contact, and the contact surfaces of the adjusting block 32 and the limiting block 33 are both provided with guide inclined surfaces on both sides;

[0058] When the upper and lower handles 28 are butt-jointed to form a hand wheel, the plurality of limiting blocks 33 are circumferentially uniformly distributed on the hand wheel, and at this time, the upper and lower strip plates 31 butt-joint to form a circular ring, and the plurality of adjusting blocks 32 are circumferentially uniformly distributed on the circular ring, when the split cylinder 100 is welded and processed, the plurality of adjusting blocks 32 and the plurality of limiting blocks 33 abut against each other correspondingly, so as to abut and fix the circular ring, at this time, the dynamic friction plate 35 abuts against one side of the static friction plate 36, the static friction plate 36 and the roller 24 are locked and fixed, and the spring 37 is in a compressed and contracted state; when the hand wheel is rotated to adjust the angle of the split cylinder 100, the hand wheel simultaneously drives the plurality of limiting blocks 33 thereon to make circumferential movement, so that the limiting block 33 and the corresponding adjusting block 32 gradually deviate from each other, at this time, the adjusting block 32 and the strip plate 31 are no longer abutted and limited, the strip plate 31 moves outward under the restoring force of the spring 37, and at the same time, the strip plate 31 pulls the dynamic friction plate 35 outward through the push-pull rod 34, so that the dynamic friction plate 35 is separated from the static friction plate 36, at this time, the static friction plate 36 and the roller 24 are unlocked, so that the roller 24 rolls and supports the inner positioning plate 25 when the inner positioning plate 25 and the split cylinder 100 rotate, so as to reduce the frictional resistance of the inner positioning plate 25 when rotating, and make the split cylinder 100 more labor-saving when rotating and adjusting;

[0059] Meanwhile, the hand wheel rotates to drive the limiting block 33 on it to move to the position of the next adjacent adjusting block 32.

By arranging the four limiting blocks 33 and the four adjusting blocks 32, when the hand wheel rotates by 90°, the limiting block 33 just abuts against the next adjacent adjusting block 32 to lock the roller 24, so that the steam cylinder 100 is welded and processed again, and at this time, the steam cylinder 100 also rotates by 90°. Through the cooperation of the locking mechanism 3, the steam cylinder 100 can just rotate by 90° during each rotation adjustment, so that the steam cylinder 100 is not adjusted too large or too small, which is not conducive to the welding and processing.

At the same time, the limit assembly abuts against the end position of the unlocking assembly, and the unlocking assembly and the locking assembly abut and lock, so that the locking assembly locks and fixes the rolling joint, so that the rolling joint and the inner clamping part are in a fixed support state, so as to increase the friction resistance of the rotation of the inner clamping part, thereby improving the stability of the installation of the inner clamping part and the sub-cylinder; Then use a welding torch to weld the sealing end of the steam sub-cylinder or the steam inlet and outlet pipes to the main cylinder of the steam sub-cylinder; When the welding process of the easy-to-process area on the cylinder is completed, the inner clamping part is driven to slide and rotate in the outer support part by the rotating drive assembly to drive the cylinder to rotate.
