[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figures 1-5 The above-displayed auxiliary device for welding stainless steel pipes includes a support platform 001. Two sets of fixing frames 101 are symmetrically arranged on one side above the support platform 001, and two sets of fixing frames 102 are symmetrically arranged on the other side above the support platform 001. A fixing frame 103 is installed at the center position above the support platform 001. An infrared laser level 104 is installed on the inner side wall and the top of the inner wall of the fixing frame 103.

[0026] The alignment of the joint between the two sets of stainless steel pipes can be measured by the infrared laser level 104 on the inner side wall and above the inner wall of the fixed frame 103, thereby ensuring the overall horizontal alignment and flatness after welding.

[0027] The docking assembly 002, located above the support platform 001, includes a slide 201. The slides 201 are symmetrically opened above the support platform 001, and the two sets of slides 201 are interconnected. A bidirectional screw 202 is rotatably connected inside the two sets of slides 201. An internal thread block 204 is symmetrically screwed onto the bidirectional screw 202. A sliding seat 203 is installed above the two sets of internal thread blocks 204.

[0028] The bidirectional screw 202 can drive two sets of internal threaded blocks 204 to move in opposite directions, thereby bringing the two sets of stainless steel pipes closer together.

[0029] The fixed adjustment assembly 003, located above the sliding seat 203, includes a guide rail 301. The guide rails 301 are symmetrically installed above the sliding seat 203. Guide sliders 302 are installed below the two sets of fixed frames 101. The guide sliders 302 are slidably connected to the corresponding guide rails 301. An electric push rod 303 is installed above the sliding seat 203. The output ends of the electric push rods 303 are arranged opposite each other and are fixedly connected to the bottom of the fixed frames 101.

[0030] By activating the electric push rod 303, the two sets of fixed frames 101 can be brought closer together to achieve a fixing effect. Furthermore, the cooperation between the guide slider 302 and the guide rail 301 can make the fixed frame 101 run more smoothly during the sliding process.

[0031] Furthermore, in the above structure, the docking component 002 also includes a guide block 205, which is symmetrically installed below the sliding seat 203. A guide groove 206 is symmetrically opened above the support platform 001, and the guide groove 206 is slidably connected to the corresponding guide block 205.

[0032] The cooperation between the guide block 205 and the guide groove 206 makes the sliding seat 203 run more smoothly during the sliding process.

[0033] Furthermore, in the above structure, the fixed adjustment assembly 003 also includes a bolt 304, which is screwed onto the inner wall of the fixed frame 101. One end of the bolt 304 near the inner side of the fixed frame 101 is rotatably connected to a spring rod 305. A fixed seat 306 is installed on one side of the spring rod 305, and a guide rod 307 is installed between the fixed seat 306 and the inner wall of the fixed frame 101.

[0034] The rotation of bolt 304 can drive spring rod 305 to move, thereby moving the position of fixed seat 306. When fixed frames 101 are close together, fixed seat 306 can fix stainless steel pipe through spring rod 305. The fixed position of stainless steel pipe can be adjusted left and right by turning bolts 304 on both sides. Guide rod 307 can ensure the stability of fixed seat 306 when it moves.

[0035] Furthermore, in the above structure, multiple sets of connecting holes 308 are provided on the inner wall of the fixed base 306, and a limiting groove 309 is provided above the inside of the connecting hole 308. A ball 310 is fitted and connected inside the connecting hole 308, and a limiting ring 311 is sleeved and fixed on the ball 310, and the limiting ring 311 is slidably connected to the limiting groove 309.

[0036] By cooperating with the limiting ring 311 and the limiting groove 309, the rotation direction of the ball 310 in the fixed seat 306 can be restricted, so that the steel pipe can only rotate and cannot be pulled between the two sets of fixed seats 306, thus avoiding positional deviation. The rotation can also ensure that the stainless steel pipe can be welded in multiple directions during welding.

[0037] Furthermore, in the above structure, the upper fixed frame 2 102 has the same structure as the fixed frame 1 101, and an electric push rod 303 is installed between the inner walls of the two sets of fixed frames 2 102. A spring rod 2 312 is installed in the lower fixed frame 2 102, and a fixed seat 306 with the same structure is installed above the spring rod 2 312. The upper and lower fixed seats 306 are arranged opposite each other.

[0038] By setting the spring rod 312, when the fixing frame 102 is close to each other, the two sets of fixing seats 306 can fix the stainless steel tube. By adjusting the position of the upper fixing seat 306, the spring rod 312 pushes the lower fixing seat 306, thereby adjusting the fixing position of the stainless steel tube up and down.

[0039] The working principle of this practical application is as follows:

[0040] Refer to the instruction manual appendix Figures 1-5A set of stainless steel pipes is fixed between two sets of fixed seats 306 by the electric push rod 303 below the first fixed frame 101. At the same time, the second fixed frame 102 moves closer together, thus fixing another set of stainless steel pipes between the two sets of fixed seats 306. At this time, the rotation of the bidirectional screw 202 causes the internal thread block 204 to drive the two sets of sliding seats 203 to move closer together, thereby making the two sets of stainless steel pipes fit together. At this time, the fit between the two sets of stainless steel pipes is detected by the infrared laser level 104. When a deviation occurs, the first fixed frame can be rotated. Bolts 304 on the top of the fixed frame 102 on both sides or above 101 are used to adjust the position of the stainless steel pipe by the fixed seat 306, so that the two sets of stainless steel pipes are in the same horizontal position. This structure can realize quick fine adjustment of the joint of the two sets of stainless steel pipes. The setting of ball bearings 310 can not only improve the fixing stability, but also facilitate the rotation of the steel pipe during the welding process, thereby realizing multi-directional welding. In addition, the infrared laser level 104 can also ensure the accuracy of the alignment, thereby improving the quality and efficiency of stainless steel pipe welding.

[0041] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
