[0028] Reference Figure 1-5This utility model discloses a multi-layer, multi-pass welding device for an aluminum motor outer cylinder, comprising a base 1. Two slide rails 2 are fixedly connected to the top of the base 1, serving as limiters and guides. A power distribution cabinet 3 is fixedly connected to the left side of the base 1, with a controller (not shown in the figure) installed externally. A chuck 4 is connected to the right side of the power distribution cabinet 3, and a motor (not shown in the figure) is installed inside the power distribution cabinet 3. The output end of the motor passes through the power distribution cabinet 3 and is fixedly connected to the chuck 4. The motor drives the chuck 4 to rotate. An adjusting seat 6 is slidably connected to the outside of the right side of the slide rails 2. Threaded rods 35 are threadedly connected to both sides of the adjusting seat 6, and rotating handles are installed on the outside of the threaded rods 35. Rotating the handles drives the threaded rods 35 to rotate, allowing them to extend into the adjusting seat 6 until they abut against the slide rails 2 for limiting the adjustment seat 6. A tailstock 5 is fixedly connected to the top of the adjusting seat 6, and a pneumatic chuck 7 is rotatably connected to the top of the tailstock 5, corresponding to the chuck 4. The pneumatic chuck 7 can rotate with the outer cylinder. Two material support assemblies are provided on the outer side of the middle section of the slide rail 2. A mounting bracket 12 is fixedly connected to the rear end of the base 1, which serves as a support. The mounting bracket 12 is located behind the base 1, so the first electric slide rail 13, the second electric slide rail 15, and the first lead screw 18 are far from the welding torch 34, avoiding the impact of welding debris on their normal operation. A movable component is installed on the top of the mounting bracket 12, and a fixed bracket 17 is connected to the top of the movable component.

The upper and lower ends of the slot 22 have through grooves to facilitate the passage of the sliding sleeve seat 25. A second lead screw 23 is rotatably connected through the slot 22. The slot 22 protects the second lead screw 23, preventing welding debris from affecting the transmission of the lead screw. The outer ring of the second lead screw 23 is threadedly connected to a sliding sleeve seat 25. The sliding sleeve seat 25 is hollow in the middle, and a slot 22 passes through its inner side.

A clamping block 33 is fixedly connected to the outside of the connecting frame 32. A welding torch 34 is installed inside the clamping block 33. The welding torch 34 is an automatic MIG welding torch, which, together with the moving components and fine-tuning components, can complete multi-layer welding of deep V-grooves, ensuring that the weld bead is filled. The clamping block 33 is fixed to the outside of the connecting frame 32 by bolts passing through it, facilitating the adjustment of the clamping block 33 and the welding torch 34. Furthermore, the welding torch 34 is set in the groove between the two clamping blocks 33, and the two clamping blocks 33 are fixedly connected by bolts. The welding torch 34 can be easily disassembled by unscrewing the bolts.A first motor 19 is fixedly connected to the top of the fixed frame 17. The output end of the first motor 19 is fixedly connected to the first lead screw 18, which can drive the first lead screw 18 to rotate.

A second motor 24 is fixedly connected to the left side of the movable seat 20, and the output end of the second motor 24 is fixedly connected to the second lead screw 23, which can drive the second lead screw 23 to rotate.

[0029] Reference Figure 1 , Figure 2 and Figure 5 The material support frame assembly includes a material support frame base 8, which is located outside the slide rail 2. An electric push rod 9 is fixedly connected to the top of the material support frame base 8, and a material support frame 10 is fixedly connected to the output end of the electric push rod 9. Rollers 11 are fixedly connected to both sides of the top of the material support frame 10. The material support frame assembly supports the workpiece, facilitating welding rotation. The electric push rod 9 controls the lifting and lowering of the material support frame, which can be adjusted according to different workpiece diameters. The moving assembly includes a first electric slide rail 13, whose bottom is fixedly connected to the mounting frame 12. A first slide block 14 is slidably connected to the outside of the first electric slide rail 13. A second electric slide rail 15 is fixedly connected to the top of the first slide block 14, and a second slide block 16 is slidably connected to the outside of the second electric slide rail 15. The top of the second slide block 16 is fixedly connected to the fixed frame 17. The moving assembly controls the upper fixed frame 17 to move left and right or forward and backward, thereby automatically adjusting the left and right and forward and backward positions of the welding torch 34.

[0030] Reference Figure 1-5 The fine-tuning assembly includes a fine-tuning seat 26, which is externally fixedly connected to a sliding sleeve seat 25. A mounting groove 28 is formed through the fine-tuning seat 26. The mounting groove 28 serves the same purpose as the slot 22, allowing the lead screw to be installed inside, preventing debris from entering and affecting the lead screw's transmission effect. A third lead screw 27 is rotatably connected through the mounting groove 28. A fine-tuning sliding sleeve 29 is threaded onto the outer ring of the third lead screw 27, and its outer surface is slidably connected to the inner wall of the mounting groove 28. The fine-tuning sliding sleeve 29 is fixedly connected to an adjusting frame 31. A knob 30 is fixedly connected to the end of the third lead screw 27, and the knob 30 is located outside the fine-tuning seat 26. The three fine-tuning components are arranged horizontally, vertically, and forward / backward, respectively. These components allow for further fine-tuning of the welding torch 34's position, improving the welding effect of the torch 34.

[0031] Working principle: The workpiece is manually hoisted onto two support frame assemblies, with the two ends of the outer cylinder aligned with chuck 4 and pneumatic chuck 7 respectively. Based on the outer cylinder diameter, the height of the support frame 10 is adjusted via electric push rod 9 to ensure the outer cylinder axis aligns with the axes of chuck 4 and pneumatic chuck 7, guaranteeing coaxiality during welding. For outer cylinders of different lengths, the threaded rods 35 on both sides of the adjusting seat 6 can be rotated, sliding the adjusting seat 6 along the slide rail 2, moving the tailstock 5 and pneumatic chuck 7 until the pneumatic chuck 7 is aligned with the right end of the outer cylinder. Then, the threaded rods 35 are tightened to fix the position of the adjusting seat 6. The pneumatic chuck 7 is activated, cooperating with the chuck 4 on the left to clamp and fix both ends of the outer cylinder, ensuring the workpiece does not shift during welding. The first electric slide rail 13 drives the first sliding block 14 to move left and right, achieving initial horizontal positioning of the welding torch 34. The second electric slide rail 15 drives the second slide block 16 to move back and forth, adjusting the distance between the welding torch 34 and the workpiece. The first motor 19 is started, driving the first lead screw 18 to rotate. Since the moving seat 20 is threadedly connected to the first lead screw 18 and its rotation is restricted by the guide rail 21, the moving seat 20 moves up and down along the guide rail 21, achieving height adjustment of the welding torch 34. The second motor 24 is started, driving the second lead screw 23 to rotate, causing the threaded sliding sleeve 25 to move along the slot 22, achieving precise positioning of the welding torch along the workpiece axis. Rotating the knob 30 drives the third lead screw 27 to rotate, causing the fine-tuning sliding sleeve 29 to move within the mounting slot 28. The fine-tuning components in three different directions—horizontal, longitudinal, and front-back—cooperate to precisely adjust the spatial posture and position of the welding torch 34, ensuring that the relative position of the welding torch 34 and the weld meets the welding requirements. During welding, the welding torch 34 begins to work, and simultaneously, the motor in the distribution cabinet 3 drives the chuck 4 to rotate, thereby rotating the workpiece for easy welding.
