DETAILED DESCRIPTION

[0016] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0017] Example: Reference Figure 1-2A stainless steel butt welded pipe positioning device includes a bottom plate 3, on which a first positioning assembly 4 and a second positioning assembly 5 are installed. The first positioning assembly 4 is used to place a first stainless steel pipe 1, and the second positioning assembly 5 is used to place a second stainless steel pipe 2, so as to achieve butt positioning of the first stainless steel pipe 1 and the second stainless steel pipe 2. The first positioning assembly 4 includes a fixing plate 6 installed on the bottom plate 3, a fixing plate 6 installed on a fixing block 7, and a positioning ring 8 installed on the fixing block 7. The fixing plate 6 and the fixing block 7 play a supporting role, and the positioning ring 8 can allow the first stainless steel pipe 1 to pass through. The positioning ring 8 is provided with a threaded hole, which is threadedly connected with the threaded rod 9. One end of the threaded rod 9 is connected with a first positioning block 10 through the threaded hole. The end of the threaded rod 9 away from the first positioning block 10 is connected with a rotating handle 16. After the first stainless steel tube 1 and the second stainless steel tube 2 are docked, the rotating handle 16 is turned to drive the threaded rod 9 to rotate. Through the threaded connection between the threaded rod 9 and the threaded hole of the positioning ring 8, the first positioning block 10 is driven to move downward until it is pressed on the upper end surface of the first stainless steel tube 1, completing the positioning of the first stainless steel tube 1. At the same time, it can be applied to first stainless steel tubes 1 of different diameters, so that one positioning device can adapt to first stainless steel tubes 1 of different sizes, with high versatility, reducing equipment costs and reducing occupied space. The positioning ring 8 is provided with a through hole, and a fixed cover 12 is installed on the positioning ring 8 above the through hole. The lower end of the fixed cover 12 is connected with a positioning rod 13, and the positioning rod 13 is connected with a second positioning block 14. The second positioning block 14 further positions the first stainless steel tube 1, making the first stainless steel tube 1 more stable during welding. The positioning rod 13 is a telescopic rod, and a spring 15 is sleeved on the positioning rod 13. One end of the spring 15 abuts against the fixed cover 12, and the other end of the spring 15 abuts against the second positioning block 14. The cooperation between the spring 15 and the telescopic rod enables the second positioning block 14 to position and fix stainless steel pipes of different diameters. Elastic parts 11 are provided on both sides of the positioning ring 8. The elastic parts 11 are thermoplastic elastomers or rubber blocks. Due to their own elastic effect, they can limit the two sides of the first stainless steel and adapt to stainless steel pipes of different diameters. The second positioning component 5 is symmetrically arranged with the first positioning component 4 with the center of the bottom plate 3 as the reference plane, which can realize the positioning of the second stainless steel pipe 2 and can be suitable for second stainless steel pipes 2 of different diameters.

[0018] The working principle of the utility model is as follows: when in use, the first stainless steel tube 1 passes through the positioning ring 8 on the first positioning component 4, and the second stainless steel tube 2 passes through the positioning ring 8 on the second positioning component 5. After the first stainless steel tube 1 and the second stainless steel tube 2 are connected, the elastic member 11 limits the two sides of the first stainless steel tube 1, and the rotating handle 16 is rotated to drive the threaded rod 9 to rotate. Through the threaded connection between the threaded rod 9 and the threaded hole of the positioning ring 8, the first positioning pressing block 10 is driven to move downward until it is pressed against the upper end surface of the first stainless steel tube 1; at the same time, the second positioning pressing block 14 is pressed against the upper end surface of the first stainless steel tube 1, and the positioning rod 13 and the spring 15 are adjusted autonomously according to the size of the first stainless steel tube 1; the second positioning component 5 repeats the above operation, thereby completing the positioning of the first stainless steel tube 1 and the second stainless steel tube 2, and works in this way.
