Description

Technical Field

[0001] The utility model belongs to the technical field of cylinder assembly, and particularly relates to a cylinder assembly butt joint tooling. Background Art

[0002] When the diameter of the cylinder is relatively large, an auxiliary tooling is required for the butt joint operation of two cylinders. The relatively large diameter of the cylinder specifically means that the diameter of the cylinder is 5 to 7 meters. As Figure 1 、 2 shown, the existing cylinder assembly butt joint tooling includes an axially adjusting device and a radially adjusting device used in cooperation. The axially adjusting device includes a first support 11, a second support 12 and a screw 13, and the radially adjusting device includes a fixed seat 14 and a bolt 15. In actual use, at least four sets of cylinder assembly butt joint tooling are installed, and at least four sets of cylinder assembly butt joint tooling are evenly distributed along the circumferential direction of the cylinder 10.

[0003] Place two cylinders 10 horizontally opposite to each other, that is, both cylinders 10 are horizontally placed, and one end of one cylinder 10 is arranged corresponding to one end of the other cylinder 10. The worker stands inside the cylinder 10, welds the first support 11 on the inner wall of the butt joint end of one cylinder 10, and welds the second support 12 on the inner wall of the butt joint end of the adjacent other cylinder 10. The first support 11 and the second support 12 are connected by a screw 13, and both the first support 11 and the second support 12 are in threaded cooperation with the screw 13. By rotating the screw 13, the distance between two adjacent cylinders 10 is adjusted. Specifically, a first nut 1101 is connected to the first support 11, a second nut 1201 is connected to the second support 12, the screw 13 is installed through the through holes on the first support 11 and the through holes on the second support 12, and both the first nut 1101 and the second nut 1201 are in threaded cooperation with the screw 13.

[0004] A fixing seat 14 is welded on the inner wall of the butt end of one of the cylinders 10. The fixing seat 14 includes a connecting block 1401, and the connecting block 1401 is welded and connected to the inner wall of the butt end of one of the cylinders 10 with a relatively lower horizontal position; on one side of the upper end of the connecting block 1401, there is an extension arm 1402 extending into the adjacent cylinder 10. There is an adjustment gap between the extension arm 1402 and the inner wall of the adjacent cylinder 10. A bolt 15 extending into the adjustment gap is installed on the extension arm 1402, and the axial direction of the bolt 15 is parallel to the radial direction of the cylinder 10. By rotating the screw 13, the two cylinders 10 are pulled closer, and by rotating the bolt 15, the cylinder 10 with a relatively higher horizontal position is pressed down, so that the two cylinders 10 are in a horizontally flush state. After the two cylinders 10 are aligned and butted, they are spot-welded. Then, the first support 11, the second support 12 and the fixing seat 14 of each set of cylinder alignment and butting tooling are removed. Since the above method has three welding points for each set of cylinder alignment and butting tooling, each set of cylinder alignment and butting tooling needs to be cut three times, which causes relatively large damage to the inner wall of the cylinder.
