Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 3 As shown, the pressure vessel positioning welding device includes a long strip-shaped base plate 1, which extends laterally. Two movable plates 2 are arranged along the length of the base plate 1. The movable plates 2 are driven by a power component and move left and right along the length of the base plate 1. In this embodiment, a guide rail 3 extending left and right along the length of the base plate 1 is bolted to the top of the base plate 1. Two guide rails 3 are arranged side-by-side, and the two movable plates 2 are simultaneously slidably mounted on the two guide rails 3, thereby improving the stability of the left and right sliding of the movable plates 2. The power component includes a horizontally moving cylinder 4 mounted on the movable plates 2. A horizontally moving cylinder 4 is bolted to the front and rear sides of each movable plate 2. Connecting plates 5 are bolted to the left and right ends of the base plate 1. The piston rod of the horizontally moving cylinder 4 extends towards the corresponding connecting plate 5, and the piston rod of the horizontally moving cylinder 4 is bolted to the corresponding connecting plate 5. Specifically, the extension of the horizontally moving cylinder 4 causes the two movable plates 2 to move closer together, or the retraction of the horizontally moving cylinder 4 causes the two movable plates 2 to move away from each other.

[0024] The tops of the two movable plates 2, which are close to each other at one end, are respectively equipped with cylindrical support assemblies 6, such as... Figure 3As shown, the cylindrical section support assembly 6 includes two sliding plates 7 arranged opposite each other along the width direction of the base plate 1. The tops of the two sliding plates 7 are respectively rotatably mounted with rollers 8 extending left and right along the length direction of the base plate 1. The two rollers 8 can support a cylindrical section 20. In this embodiment, the tops of the sliding plates 7 are fixedly mounted with two vertical plates arranged opposite each other by bolts, and the two ends of the corresponding rollers 8 are respectively rotatably mounted on the two vertical plates via bearings.

[0025] During welding, a cylindrical section 20 is placed horizontally on each of the two movable plates 2, and the corresponding cylindrical section 20 is supported by the two rollers 8 on the movable plates 2; then, the horizontal moving cylinder 4 extends to drive the two movable plates 2 to move closer to each other, so that the ends of the two cylindrical sections 20 are joined together, and then the joint of the two cylindrical sections 20 is welded.

[0026] like Figure 2 As shown, in this embodiment, the top of the movable plate 2 is provided with a groove 9. A slide rod 10 extending back and forth along the width direction of the base plate 1 is fixedly installed in the groove 9 by bolts. Both slide plates 7 are slidably installed on the slide rod 10, so that the positions of the slide plates 7 and the rollers 8 can be adjusted back and forth. A double-rod cylinder 11 is also installed in the groove 9 between the two slide plates 7 by bolts. The two piston rods of the double-rod cylinder 11 extend toward the two slide plates 7 respectively, and the two piston rods of the double-rod cylinder 11 are fixedly connected to the two slide plates 7 by bolts respectively.

[0027] When the ends of the two cylindrical sections 20 are joined, if there is a height difference between the two cylindrical sections 20, the double-rod cylinder 11 on one of the movable plates 2 can be adjusted. By retracting the double-rod cylinder 11, the two rollers 8 are driven to move closer to each other, thereby raising the corresponding cylindrical section 20. Alternatively, by extending the double-rod cylinder 11, the two rollers 8 are driven to move away from each other, thereby lowering the corresponding cylindrical section 20. This will adjust the two cylindrical sections 20 to the same height and further improve the welding quality.

[0028] like Figure 1 and Figure 2 As shown, two movable plates 2 are respectively fixedly installed on the top of their opposite ends. The uprights 12 include two columns 13 arranged in opposite directions. The lower ends of the columns 13 are fixedly installed on the movable plates 2 by bolts. A fixing plate 14 is welded between the two columns 13.

[0029] A push plate 15 is provided on the side of the upright 12 near the cylindrical support assembly 6. Guide rods 16 are welded to the four corners of the push plate 15 near the corresponding upright 12. The guide rods 16 extend left and right along the length of the base plate 1. Both columns 13 are provided with guide holes that match the guide rods 16. The guide rods 16 are slidably mounted on the two columns 13. An adjusting cylinder 17 is bolted to the side of the fixed plate 14 away from the push plate 15. The piston rod of the adjusting cylinder 17 passes through the fixed plate 14 and extends towards the corresponding push plate 15. The piston rod of the adjusting cylinder 17 is fixedly connected to the push plate 15 by bolts.

[0030] When the two movable plates 2 approach each other and drive the ends of the two cylindrical sections 20 to be joined together, the extension of the adjusting cylinder 17 drives the push plate 15 to move towards the cylindrical section 20. The two push plates 15 respectively abut against the ends of the two cylindrical sections 20 that are far apart from each other, thereby axially pressing the two cylindrical sections 20 together and making the end faces of the two cylindrical sections 20 tightly joined, thereby improving the welding quality.

[0031] One of the slide plates 7 of the cylindrical section support assembly 6 is bolted with a motor 18 for driving the corresponding idler roller 8 to rotate. The motor shaft of the motor 18 is connected to the corresponding idler roller 8 via a belt 19. After the two push plates 15 axially press the two cylindrical sections 20 together, the worker can weld the joint between the two cylindrical sections 20. After the worker finishes welding the joint at the top of the two cylindrical sections 20, the push plates 15 are disengaged from the ends of the cylindrical sections 20 by adjusting the cylinder 17. Then, the two motors 18 drive the two idler rollers 8 to rotate synchronously, and the idler rollers 8 drive the two cylindrical sections 20 to rotate at a certain angle, so that the joint between the two cylindrical sections 20 that has not yet been welded is rotated to its top, thereby reducing the welding difficulty and improving the welding efficiency.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
