Description

Technical Field

[0001] The invention belongs to the technical field of stainless steel flat plates, and in particular relates to a welding device for stainless steel flat plates. Background Art

[0002] Stainless steel plates are widely used in many fields such as construction, machinery manufacturing, chemical equipment, transportation, etc. due to their excellent properties such as corrosion resistance, high strength, beauty and durability. In the processing and manufacturing of stainless steel plates, welding is a crucial process. Through welding, different stainless steel plates can be connected into components that meet specific size and structural requirements, thereby realizing their assembly application in various equipment and facilities.

[0003] Existing stainless steel plate welding assist devices often face issues with unstable driving force and large deviations in movement trajectory when moving the plate. Most devices rely on a single drive mechanism, making it difficult to adjust the driving force and travel distance for stainless steel plates of varying sizes. This results in the plate easily drifting during movement, preventing it from accurately reaching the desired welding position.

[0004] Therefore, when it comes to docking stainless steel plates of different specifications, especially those with different sizes, traditional devices lack an efficient automatic alignment mechanism. Either the alignment action cannot be automatically triggered, or the alignment structure is not adaptable enough to meet the docking requirements of plates of different sizes, resulting in problems such as misaligned docking edges and uneven gaps.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0021] Example 1: like Figures 1 to 10 As shown, a welding device for stainless steel flat plates includes a mounting base 1, two beams 11 disposed above the mounting base 1, a plurality of equally spaced crossbeams 111 disposed between the two beams 11, and a first hydraulic cylinder 13 disposed on either side of the crossbeam 111. A first stainless steel flat plate 14 and a second stainless steel flat plate 141 are also placed above the crossbeam 111, and a mounting block 132 is disposed at the output end of the first hydraulic cylinder 13. Two rotating rods 3 are also disposed above the crossbeam 111, the two rotating rods 3 being symmetrical to each other, and the bottoms of the two rotating rods 3 are both provided with second bearings 313, the two second bearings 313 being symmetrical to each other. A push plate 2 is also disposed above the crossbeam 111, and is used to drive the second stainless steel flat plate 141 to move, and is also used to drive the rotating rod 3 to rotate. The first stainless steel plate 14 is driven to move by the first hydraulic cylinder 1 to adapt to plates of different sizes. During the adjustment process, after the rectangular plug-in rod 21 of the push plate 2 contacts the first stainless steel plate 14, it is linked by the fixed plate 212, the first rocker arm 22, the second rocker arm 223, etc. to drive the moving rod 33 to align the first stainless steel plate 14, and then the flip plate 34 is tightened to achieve precise alignment, reducing manual operation and improving alignment accuracy.

[0022] like Figures 1 to 3 As shown, in a specific embodiment, two support legs 12 are disposed above the two crossbeams 111. The two support legs 12 are symmetrical to each other. A top plate 121 is disposed above the two support legs 12. An electric push rod 122 is disposed at the bottom of the top plate 121. A welding assembly 123 is disposed at the output end of the electric push rod 122. In this configuration, the installation position of the welding assembly 123 is determined.

[0023] Example 2: The difference between the above embodiment and this embodiment is that: Figures 1 to 9 As shown, a welding device for stainless steel plates is shown. A push plate 2 is placed on a crossbeam 111. The push plate 2 is located outside a second stainless steel plate 141. Two symmetrical notches are provided on the push plate 2, and rectangular plug rods 21 are placed in the inner cavities of the notches. A fixed plate 212 is provided at one end of the two rectangular plug rods 21 away from the second stainless steel plate 141. Two first return springs 211 are provided on the fixed plate 212. The two first return springs 211 are symmetrical to each other, and the other ends of the two first return springs 211 are provided on the push plate 2. This arrangement ensures that when the first stainless steel plate 14 moves horizontally, it will first contact the rectangular plug rods 21 that are movably connected to the push plate 2, thereby pushing the rectangular plug rods 21 to move horizontally. When the rectangular plug rods 21 move horizontally, they can also drive the fixed plate 212 to move horizontally.

[0024] like Figures 1 to 7 and Figure 9 As shown, in a specific embodiment, a first swing link 22 is provided on each side of the push plate 2. The two first swing links 22 are symmetrical to each other. A first rotating link 222 is provided through each end of the two first swing links 22 away from the push plate 2. The two first rotating links 222 are symmetrical to each other. A first bearing 221 is provided at the bottom of each first rotating link 222. A second swing link 223 is also provided on each first rotating link 222. The two second swing links 223 are symmetrical to each other. This arrangement ensures that when the fixed plate 212 moves horizontally, it can push the two first swing links 22 to rotate with the assistance of the first rotating link 222 and the first bearing 221. When the first rotating link 222 rotates, it can also drive the second swing link 223 to rotate.

[0025] Example 3: The difference between the above embodiment and this embodiment is that: Figures 1 to 7 and Figure 9As shown, a welding device for stainless steel flat plates is shown. Two rotating rods 3 are each provided with a first placement plate 31. The two first placement plates 31 are symmetrical with each other. Opposite side walls of the two first placement plates 31 are each provided with a movable groove 311. The two movable grooves 311 are symmetrical with each other. A movable slider 312 is slidably disposed within the inner cavities of the two movable grooves 311. The two movable sliders 312 are symmetrical with each other. The ends of the two movable sliders 312, each distal from the movable groove 311, are respectively affixed to the second rocker 223. This arrangement ensures that when the second rocker 223 rotates, it can drive the first placement plates 31 to rotate with the assistance of the rotating rod 3. Rotation of the rotating rod 3 also drives the second placement plate 32 to rotate.

[0026] like Figures 1 to 7 and Figure 9 As shown, in the specific embodiment, the two rotating rods 3 are further provided with second placement plates 32, the two second placement plates 32 are symmetrical to each other, and a rectangular notch 321 is opened through the middle of the two second placement plates 32. In this setting, the opening position of the rectangular notch 321 is determined.

[0027] like Figures 1 to 7 and Figure 9 As shown, further, the inner cavities of the two rectangular slots 321 are each provided with a movable rod 33. The two movable rods 33 are symmetrical with each other, and a connecting plate 331 is provided on opposite ends of the two movable rods 33. The two connecting plates 331 are symmetrical with each other, and a second return spring 333 is provided on opposite ends of the two second return springs 333. A placement block 322 is provided on the placement block 322. A mounting plate 323 is provided on the placement block 322, and a slide rail 332 is provided at the bottom of the mounting plate 323. The slide rail 332 and the connecting plate 331 are slidably arranged. This arrangement ensures that when the second placement plate 32 rotates, it can drive the mounting plate 323 to rotate, thereby driving the placement block 322 to rotate through the mounting plate 323, and the connecting plate 331 to rotate through the slide rail 332. Therefore, the movable rod 33 and the second return spring 333 can be driven to rotate, so that the movable rod 33 can contact the side wall of the first stainless steel plate 14, thereby straightening the first stainless steel plate 14.

[0028] like Figures 1 to 7 and Figure 9 as well as Figure 10 As shown, third bearings 341 are disposed on opposite sides of the inner cavity of the two rectangular slots 321. A rotating shaft 342 is disposed between each of the third bearings 341. The two rotating shafts 342 are symmetrical to each other, and a flip plate 34 is disposed on each rotating shaft 342. In this arrangement, the installation position of the flip plate 34 is determined, ensuring that the flip plate 34 can rotate.

[0029] like Figures 1 to 7 and Figure 9 as well as Figure 10 As shown, the two flip plates 34 are symmetrical to each other. Torsion springs 343 are provided on the upper and lower sides of the flip plates 34, respectively, and the other ends of the torsion springs 343 are mounted on third bearings 341. A swing arm 344 is provided on each flip plate 34 near one end of the movable rod 33, and the other ends of the swing arms 344 are movably mounted on the movable rod 33. This arrangement ensures that when the movable rod 33 contacts the side wall of the first stainless steel plate 14, the second placement plate 32 continues to rotate, thereby allowing the movable rod 33 to move backward with the assistance of the connecting plate 331 and the slide rail 332. When the movable rod 33 moves, the swing arm 344 drives the flip plates 34 to rotate with the assistance of the rotating shaft 342 and the third bearing 341, thereby allowing the flip plates 34 to abut the side wall of the first stainless steel plate 14. At this time, the second stainless steel plate 141 is in contact with the first stainless steel plate 14, thereby achieving alignment between the first stainless steel plate 14 and the second stainless steel plate 141.

[0030] The implementation principle of the stainless steel flat plate welding device of this embodiment is as follows: First, the staff places the first stainless steel plate 14 and the second stainless steel plate 141 of different sizes on the beam 111 respectively. When the placement is completed, the staff controls the first hydraulic cylinder 13 to operate, so that the first hydraulic cylinder 13 can drive the mounting block 132 to move horizontally, thereby driving the first stainless steel plate 14 to move horizontally; When the first stainless steel plate 14 moves horizontally, it will first contact the rectangular plug-in rod 21 that is movably plugged into the push plate 2, so it can push the rectangular plug-in rod 21 to move horizontally. When the rectangular plug-in rod 21 moves horizontally, it will drive the fixed plate 212 to move horizontally. When the fixing plate 212 moves horizontally, it will be able to squeeze the two first rocking rods 22 to rotate with the assistance of the first rotating rod 222 and the first bearing 221. When the first rotating rod 222 rotates, it will be able to drive the second rocking rod 223 to rotate. When the second rocking rod 223 rotates, it will be able to drive the first placement plate 31 to rotate with the assistance of the rotating rod 3. When the rotating rod 3 rotates, it can also drive the second placement plate 32 to rotate. When the second placement plate 32 rotates, it will be able to drive the mounting plate 323 to rotate, thereby driving the placement block 322 to rotate through the mounting plate 323, and driving the connecting plate 331 to rotate through the slide rail 332, thereby driving the moving rod 33 and the second return spring 333 to rotate, so that the moving rod 33 can contact the side wall of the first stainless steel plate 14, thereby straightening the first stainless steel plate 14. When the moving rod 33 contacts the side wall of the first stainless steel plate 14, the second placement plate 32 continues to rotate, so that the moving rod 33 can move backward with the assistance of the connecting plate 331 and the slide rail 332. When the moving rod 33 moves, the swing arm 344 can drive the flip plate 34 to rotate with the assistance of the rotating shaft 342 and the third bearing 341, so that the flip plate 34 can be pressed against the side wall of the first stainless steel plate 14. At this time, the second stainless steel plate 141 is in contact with the first stainless steel plate 14, so that the first stainless steel plate 14 and the second stainless steel plate 141 can be aligned; When the first stainless steel plate 14 and the second stainless steel plate 141 are aligned, the worker controls the electric push rod 122 and the welding assembly 123 to operate, thereby being able to weld the connection between the first stainless steel plate 14 and the second stainless steel plate 141 .
