Description

Technical Field

[0001] This utility model relates to the field of welding platform technology, specifically a boom assembly tilting welding platform. Background Technology

[0002] The boom assembly is a key structural component in construction machinery (such as excavators, loaders, cranes, etc.). It is usually composed of the boom, stick, cylinder, connecting pin, structural components (such as steel plates and profiles), and auxiliary devices (such as hydraulic lines and sensors). It is the core component for the equipment to perform digging, lifting, loading and unloading actions, and directly affects the performance and reliability of the equipment. Therefore, the boom body is usually welded from thick steel plates to ensure that it has high strength and fatigue resistance.

[0003] During the welding process, the slag formed after the welding rod or welding wire melts may splash into the surrounding area, forming scattered metal particles or fragments, which not only poses certain safety hazards, but is also quite cumbersome to clean up. Utility Model Content

Two sliding rods 4 are symmetrically arranged on both sides inside the lifting frame 3. An adjusting seat 5 is slidably connected to the surface of the sliding rod 4. A motor 6 is fixedly connected to the top side of the adjusting seat 5. An adjusting screw 7 is fixedly connected to the output shaft of the motor 6. An adjusting sleeve 8 is threadedly connected to the surface of the adjusting screw 7. A dust cover 12 is fixedly connected to the bottom of the adjusting sleeve 8.

[0022] A sliding column 9 is fixedly connected to the bottom of the adjusting seat 5 on the side away from the motor 6. A sliding sleeve 11 is slidably connected to the bottom of the sliding column 9. The sliding sleeve 11 and the dust cover 12 are fixedly connected. A connecting spring 10 is fixedly connected between the sliding sleeve 11 and the sliding column 9.

[0023] When the motor 6 is started, its output shaft drives the adjusting screw 7 to rotate, and the adjusting sleeve 8 rotates accordingly. At the same time, the sliding column 9 and the sliding sleeve 11 slide relative to each other, the connecting spring 10 deforms, and drives the dust cover 12 to move down. Thus, when the welding head 16 is working, the dust cover 12 blocks the welding slag generated by welding and prevents it from splashing everywhere.

A moving plate 23 is fixedly connected to the end of the connecting rod 22 away from the threaded sleeves 21. The moving plate 23 is slidably connected to the top of the worktable 18.

[0027] When the motor 19 is started, its output shaft drives the bidirectional lead screw 20 to rotate, and the threaded sleeve 21 rotates accordingly. The connecting rod 22 moves the moving plate 23 through the limit of the through hole on the worktable 18. The sliding sleeve 34 slides on the surface of the rotating shaft 32. The sliding sleeve 34 and the rotating shaft 32 are respectively provided with grooves and protrusions. The grooves and protrusions are matched to limit the circumferential movement of the two. While the rotating shaft 32 drives the sliding sleeve 34 and the fixed clamping plate 35 to rotate, the moving plate 23 drives the fixed clamping plate 35 to limit the movement of the parts, thereby ensuring stability during the welding process.

[0028] A cylinder 24 is fixedly connected to the bottom of the workbench 18 near the mounting frame 1. A rack plate 25 is fixedly connected to the top of the cylinder 24. The rack plate 25 slides on one side of the mounting frame 1 via a slider.

[0029] Two rotating seats 26 are symmetrically welded on the side of the mounting bracket 1 near the rack plate 25. A rotating rod 27 is rotatably connected inside the rotating seat 26. A drive gear 28 is fixedly sleeved on the surface of the rotating rod 27. The drive gear 28 meshes with the rack plate 25. Drive wheels 29 are symmetrically sleeved on both sides of the surface of the rotating rod 27. A toothed belt 30 meshes on the surface of the drive wheel 29.

[0030] The top two sides of the workbench 18 are symmetrically welded with fixed plates 31. The fixed plates 31 are rotatably connected to the shaft 32. The surface of the shaft 32 is fixedly sleeved with a transmission wheel 33. The transmission wheel 33 is located on the side of the fixed plate 31 away from the moving plate 23.

The sliding sleeve 34 is rotatably connected to the moving plate 23. The end of the sliding sleeve 34 away from the shaft 32 is fixedly connected with a fixed clamping plate 35.

[0031] When cylinder 24 is started, its output rod moves rack 25, drives gear 28 to rotate, and drives rod 27 and drive wheel 29 to rotate. Power is transmitted to transmission wheel 33 through toothed belt 30, causing shaft 32 to drive sliding sleeve 34 and fixed clamping plate 35 to rotate, thereby flipping boom assembly to allow welding on other sides.

[0032] This utility model provides a boom assembly tilting and welding platform, the specific working principle of which is as follows:

[0033] In use, the boom assembly is placed between the two fixed clamping plates 35. Motor 19 is started, its output shaft drives the bidirectional lead screw 20 to rotate, and the threaded sleeve 21 rotates accordingly. The connecting rod 22 moves the moving plate 23 via the limit of the through hole on the worktable 18. The sliding sleeve 34 slides on the surface of the rotating shaft 32, thus bringing the two fixed clamping plates 35 closer to the boom assembly and fixing both sides. During welding, cylinder 17 is started, its output rod driving the lifting frame 3 and welding head 16 downwards to weld the joint. Motor 6 is started, its output shaft driving the adjusting screw 7 to rotate, and the adjusting sleeve 8 rotates accordingly. Simultaneously, the sliding column 9 and the sliding sleeve 11 slide relative to each other, connecting... Spring 10 deforms and causes dust cover 12 to move downward, thus blocking the welding slag generated during welding of welding head 16 and preventing it from splashing everywhere. Motor 13 is started, screw 14 rotates, and adjusting seat 5 drives welding head 16 to move back and forth to adjust the welding position. After welding on one side is completed, cylinder 24 is started, its output rod drives rack plate 25 to move, drives gear 28 to rotate, and drives rotating rod 27 and drive wheel 29 to rotate. Power is transmitted to transmission wheel 33 through toothed belt 30, causing rotating shaft 32 to drive sliding sleeve 34 and fixed clamping plate 35 to rotate, thereby flipping the boom assembly to weld other sides.
