The operator needs to hold the welding torch while the robot rotates around the product for circumferential welding. This method reduces operator workload, although adjusting the robot's position is inconvenient; however, the welding efficiency remains low. Therefore, improving welding efficiency is a direction that those skilled in the art need to explore. Summary of the Invention

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0024] Example 1: See Figure 1-3 As shown, a circumferential seam welding device includes a machine base 1, a support component 2, a material pressing component, and a welding torch 3. The support component 2 is rotatably mounted on the machine base 1 via a first drive unit 4. The material pressing component includes a pressure rod 5, a mounting plate 6, and a vertical drive unit 7. The top of the pressure rod 5 is rotatably connected to the mounting plate 6. The vertical drive unit 7 is configured to drive the mounting plate 6 to move vertically and is positioned directly above the support component 2. The welding torch 3 is connected to the mounting plate 6 via a connecting component.

[0025] The connecting components include a first connector 8, a second connector 9, and a cylinder 10. The top of the first connector 8 is connected to the mounting plate 6, the cylinder 10 is mounted on the first connector 8, and the welding torch 3 is connected to the output shaft of the cylinder 10 via the second connector 9.

[0026] In this invention, during actual use, the product to be welded is placed on a supporting component, which supports the product. Then, a vertical drive unit drives a mounting plate downwards, causing a pressure rod to press against the top of the product. Simultaneously, the welding torch moves downwards with the mounting plate, aligning its welding tip with the area to be welded. The cylinder's output shaft then extends, allowing the welding tip to press against the welding point and begin welding. During welding, the first drive unit rotates the supporting component. Because the product is placed on the supporting component and the pressure rod is pressing on it, the rotation of the supporting component by the first drive unit causes the product to rotate as well. Therefore, automated circumferential welding of the product can be achieved during the welding process, effectively improving welding efficiency and reducing the labor intensity of operators. After welding is complete, the cylinder's output shaft retracts, detaching from the product. Then, the vertical drive unit moves the mounting plate, pressure rod, and welding torch upwards and detaches from the product. Operators or a robotic arm can then replace the product with a new one for welding. The first and second connecting parts facilitate adjustment of the welding torch's angle and position, making it suitable for different products. Of course, the support components can be detached and connected to the machine base. Different sizes and shapes of support components can be replaced according to different products to make them suitable for different products and improve the scope of application.

[0027] See Figure 3 As shown, the first connecting member 8 includes a connecting plate 11, a first adjusting bracket 12 and a second adjusting bracket 13. The connecting plate 11 is connected to the mounting plate 6. The first adjusting bracket 12 is installed on the left side wall of the connecting plate 11. The second adjusting member 13 is installed on the first adjusting bracket 12. The cylinder 10 is installed on the second adjusting bracket 13.

[0028] The first adjustment frame 12 is provided with two parallel first guide rods 14. The first adjustment frame 12 is also provided with a first adjustment screw 15 parallel to the first guide rods 14. A first slider is slidably provided on the first guide rods 14. The first slider is screwed to the first adjustment screw 15. The second adjustment frame 13 is connected to the first slider.

[0029] One side of the second adjustment frame 13 is connected to the first slider, and the other side of the second adjustment frame 13 is provided with a second slide rail 16. The second slide rail 16 is set perpendicular to the first guide rod 14. The cylinder 10 is installed on the top of the second adjustment frame 13. The second slider 17 is slidably provided on the second slide rail 16. The welding torch 3 is connected to the second slider 17 via the second connector 9. The output shaft of the cylinder 10 is connected to the top of the second slider 17.

[0030] In this embodiment, the cylinder is mounted on the first connecting member. To facilitate adjustment of the cylinder's angle and position, allowing the welding head of the welding torch to correspond to the welding points of different products, the first connecting member comprises a connecting plate, a first adjusting frame, and a second adjusting frame. The first adjusting frame is connected to the connecting plate and the mounting plate. A first adjusting screw, a first guide rod, and a first slider are mounted on the first adjusting frame. The second adjusting frame is mounted on the first slider. Taking the illustrated direction as an example, the first guide rod and the first adjusting screw are arranged longitudinally. According to the position that the welding torch needs to be adjusted, rotating the first adjusting screw can adjust the front-to-back position of the first slider, thereby adjusting the front-to-back position of the welding torch. A first gripper 18 is provided at the front end of the first adjusting frame. The first gripper is connected to the first adjusting screw, allowing for quick and convenient rotation of the first adjusting screw, thereby adjusting the longitudinal position of the first slider and the cylinder. The second connector slides on the second slide rail of the second adjustment frame via the second slider, thereby supporting the second connector. This allows the welding torch to move up and down relative to the second slide rail stably when the cylinder output shaft extends and retracts, without applying radial force to the cylinder output shaft, thus extending the cylinder's service life.

[0031] See Figure 3 As shown, the bottom surface of the mounting plate 6 is provided with an extension plate 19, and the extension plate 19 is provided with a central hole and positioning holes symmetrically arranged on both sides of the central hole.

[0032] The top of the connecting plate 11 is provided with a fixing hole 20 and arc-shaped holes 21 symmetrically arranged on both sides of the fixing hole 20. The fixing hole 20 is directly opposite the middle hole, and each arc-shaped hole 21 is directly opposite a positioning hole.

[0033] It is also provided with a connecting shaft 22 and two locking bolts 23, wherein the connecting shaft 22 is inserted into the intermediate hole and the fixing hole;

[0034] Each of the locking bolts 23 is inserted into a positioning hole and an arc hole respectively, and the connecting plate and the extension plate are locked and fixed.

[0035] To facilitate adjustment of the welding torch's tilt angle and the front-to-back position of the welding head, and to facilitate the connection between the connecting plate and the mounting plate, fixing holes and arc-shaped holes are provided on the connecting plate. The arc-shaped holes are coaxial with the fixing holes. A central hole and a positioning hole are provided on the extension plate. A connecting shaft is inserted into the central hole and the fixing hole to rotatably connect the connecting plate and the extension plate. Locking bolts are inserted into the arc-shaped holes and the positioning holes to fix the extension plate and the connecting plate. Adjusting the angle between the connecting plate and the extension plate is simple: loosen the locking bolts to rotate the connecting plate around the connecting shaft, then tighten the locking bolts to secure it. Adjustment is quick and easy.

[0036] See Figure 3 As shown, the second connecting member 9 includes a connecting rod 24, a clamping plate 25, and a second connecting plate 26. One end of the connecting rod 24 is provided with a sleeve hole 27, and the middle part of the welding gun 3 is installed in the sleeve hole 27. The other end of the connecting rod 24 is connected to the clamping plate 25. The top of the clamping plate 25 is connected to the output shaft of the cylinder 10 via the second connecting plate 26 and the second slider 17. The second connecting plate 26 and the second slider 17 are fixedly connected.

[0037] The clamping plate 25 is provided with at least one first screw hole 28, the second connecting plate 26 is provided with at least three second screw holes 29 spaced apart, and a second bolt 30 is also provided. The second bolt 30 passes through one of the second screw holes 29 and is screwed to one of the first screw holes 28.

[0038] In this embodiment, the sleeve hole of the connecting rod is used to fix the welding gun. A fixing bolt is screwed onto the connecting rod, with the inner end of the fixing bolt inserted into the sleeve hole and abutting against the outer surface of the welding gun to fix it. A clamping plate and a second connecting plate are provided. The second connecting plate is used to fix the second slider, and the clamping plate is used to connect the second connecting plate and the connecting rod. The clamping plate has multiple first screw holes arranged at intervals from bottom to top, and the second connecting plate has three second screw holes arranged at intervals from bottom to top. The second bolt passes through one of the second screw holes and one of the first screw holes to fix the clamping plate and the second connecting plate. In this way, the included angle between the clamping plate and the second connecting plate can be easily adjusted, that is, the angle and height position of the welding head of the welding gun can be adjusted. When it is necessary to adjust the height position of the welding gun, the second bolt is unscrewed, the first screw hole of the clamping plate and the second screw hole of the required positioning height are adjusted, and then the second bolt is inserted into the first screw hole and the second screw hole to lock it. When the welding torch welding head angle needs to be adjusted, loosen the second bolt, rotate the clamp plate, adjust the relative angle between the clamp plate and the second connecting plate, and then tighten the second bolt. The adjustment is convenient and quick.

[0039] See Figure 1 , 2As shown, the support component is rotatably mounted on the top surface of the machine platform, and the first drive unit is disposed on the machine platform below the support component. The first drive unit is a motor, and the motor drives the support component to rotate.

[0040] The motor is rotatably connected to the reducer and the support component, thereby stably driving the support component to rotate.

[0041] The vertical drive unit uses a vertical cylinder, and a guide rod 31 is set on each side of the mounting plate. The middle part of the guide rod is connected to the machine tool. When the vertical cylinder drives the mounting plate to move vertically, the guide rod can guide the vertical movement, thereby ensuring the stability and smoothness of its vertical movement.
