[0031] like Figure 1 and Figure 2 As shown, the utility model proposes an automatic surface welding device for metal product processing, comprising a base plate 1, and also comprising a splicing mechanism 2 for driving two parts of the metal product to be close. The splicing mechanism 2 comprises a vertical plate 21 and a rotating disk 22. Two groups of rotating disks 22 are respectively rotatably connected to two groups of vertical plates 21 arranged on the top of the base plate 1, and the rotating disk 22 keeps rotating in place. The splicing mechanism 2 also comprises a slide rail 23 and a hydraulic cylinder 24. Both groups of vertical plates 21 are slidably connected to the slide rail 23 installed on the top of the base plate 1. The slide rail 23 is a T-shaped structure, so that the movement of the vertical plate 21 is stable. The two groups of hydraulic cylinders 24 installed on the top of the base plate 1 are respectively arranged on the side where the two groups of vertical plates 21 are away from each other. The output end of the hydraulic cylinder 24 is fixedly connected to the vertical plate 21. The hydraulic cylinder 24 is used to drive the two groups of vertical plates 21 to be close to each other so as to realize the splicing of the two parts of the metal product.

[0032] For details, please refer to Figure 1-4The welding device comprises two groups of clamping assemblies 3 installed on the splicing mechanism 2 for clamping and adjusting the metal products. The two groups of clamping assemblies 3 respectively comprise a limit block 301, an adjustment block 302, a fixed plate 303, a first screw 304, a slider 305, a first fixed block 306, a second screw 307, a second fixed block 308, a third fixed block 309, and a rotating block 310. The two groups of clamping assemblies 3 are respectively installed on the opposite sides of the two groups of rotating disks 22, and the two groups of limit blocks 301 are fixedly connected to the side of the rotating disk 22, and the rotating disk 22 drives the limit blocks 301 to rotate synchronously when rotating. The limit blocks 301 are L-shaped, and the adjustment blocks 302 are slidably connected to the two groups of limit blocks 301, so that the sliding of the adjustment blocks 302 is stable. The two groups of fixed plates 303 are symmetrically arranged on both sides of the adjusting block 302 and fixedly connected between the two groups of limit blocks 301, and the position of the fixed plates 303 is fixed. The first screw rod 304 rotatably connected to the two sets of fixed plates 303 is threadedly connected to the adjustment block 302. The fixed plate 303 rotates in place and drives the adjustment block 302 to move when rotating. The movement of the adjustment block 302 is used to adjust the position of the metal product after the rotating block 310 rotates, so as to facilitate the splicing of the two sets of metal products. The slider 305 is slidably connected to one end of the adjustment block 302. The first fixed block 306 is fixedly connected to the side of the slider 305 away from the adjustment block 302. The slider 305 is in a T-shaped structure. The slider 305 makes the movement of the first fixed block 306 stable and prevents the first fixed block 306 from being driven to rotate by the second screw rod 307. The second screw rod 307 is rotatably connected to the first fixed block 306. When the second screw rod 307 moves, it drives the first fixed block 306 to move. The side of the adjustment block 302 is fixedly connected to the second fixed block 308, the third fixed block 309 arranged between the first fixed block 306 and the second fixed block 308 is fixedly connected to one side of the rotating block 310, one end of the second screw 307 passes through the third fixed block 309 and is threadedly connected to the second fixed block 308, so as to drive the first fixed block 306 to squeeze the third fixed block 309 when the second screw 307 rotates, thereby fixing the position of the rotating block 310. The clamping assembly 3 also includes a slide groove 311, a clamping plate 312, and a third screw 313. Two sets of slide grooves 311 are opened in the rotating block 310, and the clamping plate 312 is slidably connected in the slide groove 311, and the clamping plate 312 moves smoothly. The third screw 313 is rotatably connected to the rotating block 310 and passes through the two groups of clamping plates 312. The two groups of clamping plates 312 are both threadedly connected to the third screw 313, and the two ends of the third screw 313 have opposite thread directions, so that the third screw 313 can drive the two groups of clamping plates 312 to approach each other to clamp and fix the metal product parts when rotating. A rubber pad is also provided on the side where the two groups of clamping plates 312 are close to each other to prevent mechanical force from damaging the metal product parts and increase friction to prevent sliding.Furthermore, for metal product parts with an arc-shaped exterior, the clamping plate 312 can be an arc-shaped support plate, which can cover and fix the arc-shaped metal products, and cooperate with the rubber pad to prevent the metal product parts from sliding.

[0033] The rotating blocks 310 provided in the two sets of clamping assemblies 3 are perpendicular to each other, and the two metal parts can be adjusted in two perpendicular directions, so that the joint surfaces of the two metal parts can remain parallel after adjustment, which is convenient for jointing. The limit blocks 301 provided in the two sets of clamping assemblies 3 are also perpendicular to each other. After adjusting the angle of the metal parts, the joint surfaces of the two metal parts will be staggered, so that they can be aligned by adjusting the position of the adjusting block 302, so that the two sets of rotating disks 22 are close to each other to complete the jointing of the metal parts.

[0034] Further, such as Figure 1 As shown, the welding device also includes a rotating mechanism 4 installed on the bottom plate 1 for driving the metal product to rotate. The rotating mechanism 4 includes a first pulley 41, a synchronous belt 42, a second pulley 43, a sleeve 44, and a positioning seat 45. The two groups of first pulleys 41 are respectively fixedly connected to the opposite sides of the two groups of rotating disks 22, and the first pulleys 41 drive the rotating disks 22 to rotate synchronously. The two groups of first pulleys 41 are respectively connected to the second pulleys 43 through the synchronous belts 42, and the second pulleys 43 drive the first pulleys 41 to rotate through the synchronous belts 42 when rotating. The sleeve 44 is fixedly connected to the second pulley 43, and the sleeve 44 rotates synchronously with the second pulley 43. The positioning seat 45 fixedly connected to the opposite sides of the two groups of vertical plates 21 is rotatably connected to the sleeve 44, and the positioning seat 45 enables the sleeve 44 to move with the vertical plate 21. The rotating mechanism 4 also includes a rotating rod 46, a positioning plate 47, and a servo motor 48. The rotating rod 46 is slidably connected to the two sets of sliding sleeves 44. The rotating rod 46 is in the shape of a quadrangular prism. When the rotating rod 46 rotates, it drives the two sets of sliding sleeves 44 to rotate synchronously. The rotating rod 46 is rotatably connected between the two sets of positioning plates 47 fixedly installed on the top of the bottom plate 1, and the rotating rod 46 rotates in the original position. A servo motor 48 is installed on one side of a set of positioning plates 47 away from the rotating rod 46. The output end of the servo motor 48 passes through the positioning plate 47 and is fixedly connected to the rotating rod 46. After starting, the servo motor 48 drives the rotating rod 46 to rotate.

[0035] Finally, the above-mentioned welding device also includes a welding module 5 for welding. The welding module 5 is fixed to the top of the base plate 1 through an L-shaped mounting frame 51. The welding module 5 can be driven by a linear motor and a push rod motor to adjust the welding position of the welding module 5, and cooperate with the photoelectric sensor to realize automatic welding operation.

[0036] In this embodiment, first, two metal parts are placed between two groups of clamping plates 312 in two groups of clamping assemblies 3, and the third screw 313 is rotated to drive the two groups of clamping plates 312 to slide in the slide groove 311 and approach each other to clamp the metal parts. At this time, due to the irregular surface of the metal parts, the surfaces of the two metal parts that need to be welded after being clamped cannot be aligned. The two groups of hydraulic cylinders 24 are started to push the vertical plate 21 to move under the limiting action of the slide rail 23. At this time, the two groups of vertical plates 21 approach each other, so that the two metal parts are close to each other. At this time, the second screw 307 is loosened, and the rotating block 310 rotates with the second screw 307 as the axis under the action of the third fixed block 309, thereby adjusting the angle of the two metal parts so that the surfaces to be spliced ​​are in a parallel state. Then the first screw 304 is rotated to drive the adjusting block 302 to move under the limiting action of the limiting block 301, thereby adjusting the position of the metal parts so that the two metal parts are aligned. Finally, the hydraulic cylinder 24 is started to make the two metal parts fit together, and their welding surfaces are perfectly spliced. The welding module 5 is started and the welding module 5 is brought close to the metal parts under the action of the linear motor and the push rod, and the welding module 5 is started to weld the seam. At the same time, the rotating rod 46 driven by the servo motor 48 is started to rotate. When the rotating rod 46 rotates, the sliding sleeve 44 and the second pulley 43 are driven to rotate. When the second pulley 43 rotates, the first pulley 41 is driven to rotate through the synchronous belt 42, so that the first pulley 41 drives the rotating disk 22 to rotate, and then the two metal parts rotate synchronously, so that the welding module 5 can weld the entire seam and ensure the stability of the welding. At the same time, according to the tilt position of the seam, the extension length of the two groups of hydraulic cylinders 24 can be adjusted synchronously to adjust the position of the metal parts.

[0037] The above specific embodiment is only an optional embodiment of the present invention.
