[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] like Figures 1-6 As shown, a positioning mechanism for metal plate welding includes a support plate 1, the right side of the support plate 1 is rotatably connected to the support plate 2 5, a positioning assembly 4 is fixedly installed on the side where the upper ends of the support plates 1 and 2 5 are close to each other, a limit assembly 3 is movably connected to the side where the upper ends of the support plates 1 and 2 5 are separated from each other, and a welding angle adjustment assembly 2 is fixedly installed on the right front side of the support plate 1;

[0029] The welding angle adjustment assembly 2 includes a rotating shaft 21. The front and rear outer wall portions of the rotating shaft 21 are rotatably connected to the front and rear right sides of the support plate 1. The inner wall of the left portion of the support plate 25 is fixedly sleeved with the middle portion of the outer wall of the rotating shaft 21. A gear 22 is fixedly sleeved on the front outer wall of the rotating shaft 21. A rack 23 is slidably connected to the top position of the front right portion of the support plate 1. The lower end of the rack 23 is engaged with the outer surface of the gear 22. A locking cylinder 24 is fixedly installed on the front right portion of the support plate 1. The output end of the locking cylinder 24 is fixedly connected to the right end of the rack 23.

[0030] The limiting assembly 3 includes two movable frames 31, and the rear sides of the support plate 1 and the support plate 2 5 are rotatably connected to the positions away from each other. The ends of the two screws 32 away from each other are fixedly installed with hand wheels, and the front and rear sides of the two movable frames 31 are fixedly installed with connecting plates 33. The inner walls of the bottom of the two connecting plates 33 at the rear are threadedly connected to the outer walls of the two screws 32, and the upper front ends of the two connecting plates 33 are movably connected to the top limiting mechanism 34.

[0031] The welding angle adjusting assembly 2 can adjust the angle between the support plate one 1 and the support plate two 5 according to the welding requirements of the two metal plates. The rack 23 can be pushed to slide on the support plate one 1 by the extension and retraction of the locking cylinder 24. Since the rack 23 is engaged with the gear 22, the gear 22 will rotate, thereby rotating the shaft 21. The support plate two 5 is fixedly sleeved on the outer wall of the shaft 21, so the support plate two 5 will rotate relative to the support plate one 1 by a certain angle, thereby achieving the adjustment of the welding angle. This design makes the positioning structure functional and can meet different requirements. The two metal plates of different sizes can be positioned by the limiting assembly 3, so that the two metal plates are positioned by the corresponding pressing plates 341 and the fixed plates 43. When the two fixed plates 43 act on one side of the metal plates, the two pressing plates 341 are tightly attached to the metal plates by the reaction force of the corresponding elastic members 343, thereby increasing the contact points between the positioning mechanism and the plates and improving the stability of the subsequent processing of the plates. Secondly, the screw rod 32 is rotated by rotating the hand wheel. Since the screw rod 32 is threadedly connected with the connecting plate 33, the connecting plate 33 will move along the axial direction of the screw rod 32, thereby moving the moving frame 31. In this way, the position of the moving frame 31 and the top limiting mechanism 34 can be adjusted as needed, so that the pressing plate 341 can adapt to metal plates of different lengths, thereby improving the applicability of the positioning mechanism.

[0032] As shown in Figure 4 , the bottom position of the right front side of the support plate one 1 is fixedly installed with a guide rod 25, and the left front side of the rack 23 is fixedly installed with a sliding frame 26, and the inner wall of the bottom of the sliding frame 26 is slidably connected with the outer wall of the guide rod 25.

[0033] The sliding connection of the guide rod 25 and the sliding frame 26 provides additional stability, ensuring that the rack 23 will not deviate during sliding, thereby ensuring the accuracy of angle adjustment.

[0034] As shown in Figure 3 and Figure 4 , the lower ends of the four corners of the support plate one 1 are fixedly installed with support columns 27.

[0035] The four support columns 27 support the support plate one 1 and the support plate two 5.

[0036] As shown in Figure 3 , the right side of the right two support columns 27 is provided with a sliding groove 28, and the front and rear ends of the lower end of the support plate two 5 are rotatably connected with adjusting rods 29, and the ends of the two adjusting rods 29 away from the support plate two 5 are rotatably connected with sliding blocks 210, and the front and rear sides of the two sliding blocks 210 are slidably connected with the inner walls of the two sliding grooves 28.

[0037] When the support plate two 5 rotates through the rotating shaft 21, the two moving rods 29 rotate and push or pull the corresponding sliding blocks 210 to slide in the two sliding grooves 28. The close fit between the sliding blocks 210 and the sliding grooves 28 and the support of the moving rods 29 together enhance the stability of the entire positioning mechanism during the welding process.

[0038] As shown in Figure 5 , the front sides of the support plate one 1 and the support plate two 5 are fixedly installed with limiting rods 35 at positions away from each other, and the inner walls at the bottom of the two connecting plates 33 are in sliding connection with the outer walls of the two limiting rods 35.

[0039] The two limiting rods 35 guide and limit the movement of the two moving frames 31.

[0040] As shown in Figure 5 , the top limiting mechanism 34 includes two pressing plates 341, the upper ends of the two moving frames 31 are slidingly connected with slide columns 342 penetrating through the top portions of the two moving frames 31, the lower ends of the two slide columns 342 are fixedly connected with the front upper ends of the two pressing plates 341, the upper ends of the two slide columns 342 are fixedly installed with pull plates, the outer wall top portions of the two slide columns 342 are movably sleeved with elastic members 343, and the two elastic members 343 are located between the corresponding pull plates and the moving frames 31.

[0041] Since the slide columns 342 are in sliding connection with the moving frames 31 and the elastic members 343 are arranged between the slide columns 342 and the moving frames 31, when the pressing plates 341 contact the metal plate, the elastic members 343 will be compressed to generate a reaction force, so that the pressing plates 341 are tightly attached to the metal plate to provide stable clamping force. The elastic members 343 are springs, and the compression degree can be adjusted according to the thickness of the metal plate, so as to ensure that the pressing plates 341 can always provide appropriate clamping force.

[0042] As shown in Figure 6 , the positioning assembly 4 includes two fixed frames 41, the lower ends of the two fixed frames 41 are fixedly installed at positions close to each other at the upper ends of the support plate one 1 and the support plate two 5, the inner walls of the middle portions of the rear sides of the two fixed frames 41 are in threaded connection with adjusting screws 42, the front ends of the two adjusting screws 42 are rotatably connected with fixed plates 43, the inner wall bottoms of the two fixed frames 41 are provided with moving grooves, and the lower ends of the two fixed plates 43 are in sliding connection with the inner walls of the two moving grooves.

[0043] By rotating the adjusting screws 42, the fixed plates 43 can be driven to move in the fixed frames 41. The fixed plates 43 can fix the metal plate between them and the inner walls of the fixed frames 41, so as to realize accurate positioning of the metal plate.

[0044] The utility model discloses a working principle: when using, according to the welding demand of two metal sheet material and starts locking cylinder 24, the telescopic of locking cylinder 24 can push rack 23 to slide on support plate no. 1. Because rack 23 is engaged with gear 22, gear 22 will rotate along, and then drive the rotation of rotating shaft 21. The outer wall of rotating shaft 21 is fixedly covered with support plate no. 2 5, and therefore support plate no. 2 5 will rotate a certain angle relative to support plate no. 1, to realize the adjustment of welding angle.

[0045] According to the size of two metal sheet material, rotate hand wheel, and hand wheel drives the rotation of screw rod 32. Because screw rod 32 is connected with connecting plate 33 threadedly, connecting plate 33 will move along the axial movement of screw rod 32, and then drive the movement of moving frame 31. In this way, the position of moving frame 31 and top limiting mechanism 34 can be adjusted as required, so that the compression plate 341 can adapt to metal sheet material of different lengths, and the applicability of the positioning mechanism is improved. Pull two pull plates, so that two pull plates drive corresponding compression plate 341 to move away from the upper surface of support plate no. 1 and support plate no. 2 5, and two metal sheet materials are placed on the inner wall bottom of corresponding moving frame 31 and fixed frame 41 respectively, so that two metal sheet materials are butt jointed, and two pull plates are loosened, and two compression plate 341 resets, when compression plate 341 contacts metal sheet material, elastic member 343 will be compressed, and counterforce is generated, so that compression plate 341 is closely attached to metal sheet material, and stable clamping force is provided. After the butt joint of two metal sheet materials, rotate two adjusting screw rod 42, and can drive corresponding fixed plate 43 to move in corresponding fixed frame 41. Fixed plate 43 can fix metal sheet material between it and fixed frame 41 inner wall, so as to realize the accurate positioning of metal sheet material, and facilitate the subsequent welding work of two metal sheet materials.
