[0021] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0022] This application discloses a welding apparatus for improving the connection accuracy of stainless steel pipes. (Refer to...) Figure 1 and Figure 2 The system includes a welding base 1, on which two transverse moving modules 2 are arranged along the length direction. A sliding base 3 is slidably arranged on the transverse moving modules 2. In this embodiment, the transverse moving modules 2 are linear modules used to drive the sliding base 3 to move along the length direction of the welding base 1. A mounting base 4 is arranged on the surface of the sliding base 3, and a second rotating mechanism 31 is arranged on the surface of the sliding base 3. The output shaft of the second rotating mechanism 31 is connected to the bottom wall of the mounting base 4 to drive the mounting base 4 to rotate relative to the sliding base 3, thereby facilitating the subsequent loading of stainless steel pipes.
[0023] Reference Figure 1 and Figure 2 The mounting base 4 has a vertical plate 41 on its surface. A first rotating mechanism 42 is provided on the side of the vertical plate 41 that is far apart from each other. In this embodiment, the first rotating mechanism 42 and the second rotating mechanism 31 are both in the form of motor units. The output shaft of the first rotating mechanism 42 passes through the vertical plate 41 and is connected to the mounting base 43. The mounting base 43 is rectangular. Side plates 44 are provided at both ends of the side surface of the mounting base 43 that is far away from the vertical plate 41. The side plates 44 are arranged in the horizontal direction. Several sets of U-shaped groove components 5 are provided between the upper and lower side plates 44 for fixing and supporting the stainless steel pipe. Several sets of U-shaped groove components 5 are distributed along the length direction of the transverse moving module 2 to achieve fixing and clamping of the stainless steel pipe.
[0024] Reference Figure 2 , Figure 3 and Figure 4 The U-shaped groove component 5 includes a U-shaped groove body 51, a mounting block 52, four adjusting members 53, and two positioning plates 54. Each positioning plate 54 corresponds to two adjusting members 53. The U-shaped groove body 51 is positioned between the upper and lower side plates 44, with its opening facing the upper side plate 44. The upper end of the U-shaped groove body 51 is fixedly connected to the bottom wall of the upper side plate 44 to maintain its stability. The centerline of the U-shaped groove body 51 lies on a straight line containing one of the diameters of the output shaft of the first rotating mechanism 42. The mounting block 52 is fixedly mounted on the surface of the lower side plate 44, with two adjusting members 53 positioned on its surface. The U-shaped groove body 51 is positioned between the two adjusting members 53. 3. The positioning plate 54 is set on the bottom wall of the upper side plate 44 and the piston rod end wall of the corresponding adjusting member 53. In this embodiment, the adjusting member 53 adopts a cylinder module to drive the positioning plate 54 to move. The positioning plate 54 includes straight sections 541 on both sides and an arc-shaped section 542 set between the straight sections 541 on both sides. The protruding parts of the arc-shaped sections 542 of the two positioning plates 54 are set in opposite directions to cover and press the outer surface of the stainless steel pipe with the concave part. The inner wall of the U-shaped groove body 51 is provided with an adjusting groove 511 for the two positioning plates 54 to move. The adjusting groove 511 is opened along the height direction of the U-shaped groove body 51 so that the upper and lower positioning plates 54 can move towards each other or away from each other in the adjusting groove 511.
[0025] Reference Figure 3 and Figure 4 The two straight sections 541 of the lower positioning plate 54 are each provided with abutting blocks 543. The two abutting blocks 543 are each provided with a moving part 544 on the opposite side. The piston rod of the moving part 544 is connected to the abutting block 543. In this embodiment, the moving part 544 is a cylinder module. The moving part 544 drives the abutting block 543 through the adjusting groove 511 and abuts against the outer wall of the stainless steel pipe. The bottom wall of the two straight sections 541 of the upper positioning plate 54 is provided with a relief groove 546 for the upper end of the abutting block 543 to enter. The relief groove 546 is opened along the length of the straight section 541 to reduce the risk of collision and ensure safety during operation. The side of the abutting block 543 near the stainless steel pipe is provided with a flexible pad 545 to prevent damage to the surface of the stainless steel pipe during clamping on both sides.

Two sets of feeding mechanisms 6 are also provided on the same side of the welding base 1, and the welding station 11 is located between the two sets of feeding mechanisms 6. The feeding mechanism 6 includes a pipe guide frame 61, a vertical frame 62 provided at the bottom of the pipe guide frame 61, and a pushing module 63 provided on the side of the pipe guide frame 61 away from the welding base 1. The pipe guide frame 61 includes a horizontal section 611 and an inclined section 612. 12 is set at one end of the horizontal section 611 near the welding station 11. The inclined section 612 is inclined towards the ground at the end away from the horizontal section 611. An anti-detachment plate 613 is welded to the end of the inclined section 612 away from the horizontal section 611. The anti-detachment plate 613 is set at the end away from the inclined section 612 facing obliquely upward, so that the stainless steel pipe can roll down the inclined section 612 from the horizontal section 611 until it stops after contacting the anti-detachment plate 613. The pipe guide bracket 61 is set with... The truss structure has multiple hollow sections. The feeding mechanism 6 also includes a lifting plate 64 that is lifted and lowered below the pipe guide frame 61 and several blocking teeth plates on the surface of the lifting plate 64. Part of the lifting plate 64 is set parallel to the horizontal section 611, and part is set parallel to the inclined section 612 of the pipe guide frame 61. The lifting plate 64 is raised and lowered so that the blocking teeth plates pass through the hollow part of the pipe guide frame 61, thereby separating the stainless steel pipes and reducing the speed at which the stainless steel pipes slip, thus reducing the probability of damage to the stainless steel pipes. The piston rod of the pushing module 63 is set at the junction of the inclined section 612 and the anti-detachment plate 613. The piston rod of the pushing module 63 is set towards the welding base 1. In this embodiment, the pushing module 63 adopts a cylinder propulsion module. When the second rotating mechanism 31 drives the mounting base 4 to rotate 90° relative to the sliding base 3, the stainless steel pipes on the pipe guide frame 61 can be pushed into the U-shaped groove component 5 through the pushing module 63 to achieve automatic feeding.
[0027] Reference Figure 1 , Figure 2 and Figure 5 The welding base 1 has a lifting groove 12 on its surface, which is located between the two transverse moving modules 2. A support frame 7 is installed in the lifting groove 12, and a support seat 8 is installed at the top of the support frame 7. An inclined unloading frame 9 is provided on the side of the welding base 1 away from the welding station 11. The support frame 7 includes a bottom fixed end 71 and a rotating section 72 rotatably installed on the surface of the fixed end 71. A third rotating mechanism 73 is provided on the fixed end 71 for driving the rotating section 72 to adjust. In this embodiment, the third rotating mechanism 73 is a motor module, which is used to drive the support frame 7 to rotate in the direction of the inclined unloading frame 9, so that the welded stainless steel pipe rolls from the inclined unloading frame 9 to achieve automatic unloading. A flexible stop 91 is provided at the end of the inclined unloading frame 9 away from the welding base 1 to ensure the structural safety of the stainless steel pipe.
[0028] The implementation principle of a welding device for improving the connection accuracy of stainless steel pipes according to an embodiment of this application is as follows: The second rotating mechanism 31 drives the mounting base 4 to rotate 90° relative to the sliding base 3, and then the feeding mechanism 6 automatically feeds the stainless steel pipes. After feeding is completed, the stainless steel pipes enter the U-shaped groove component 5. The position of the stainless steel pipes is adjusted by the abutment block 543 and the positioning plate 54 until the stainless steel pipes are coaxial with the axis of the first rotating mechanism 42. Through the adjustment of the second rotating mechanism 31, the lateral moving module 2 and other mechanisms, the stainless steel pipes are turned and connected. Thus, the welder can connect the stainless steel pipes fixed on both sides and coaxially at the welding station 11. The pipe is welded. During the welding process, the first rotating mechanism 42 drives the stainless steel pipe to rotate continuously, making the welding simpler and more efficient. After the welding is completed, the support frame 7 extends and supports the stainless steel pipe through the support seat 8. The U-shaped groove component 5 releases the stainless steel pipe from the fixing, and the stainless steel pipe is removed from the range of the U-shaped groove component 5 by the lateral moving module 2. Then, the support frame 7 can be driven to rotate by the third rotating mechanism 73, thereby realizing the automatic unloading of the welded stainless steel pipe. The device of this application has a high degree of automation and can continuously rotate the stainless steel pipe during the welding process, thereby effectively improving the welding accuracy and convenience of the stainless steel pipe.
[0029] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
