SUMMARY

[0004] The problems to be solved by the application are that the hoisting welding is easy to shake without an auxiliary supporting point, the welding personnel are required to have high level, and the welding gun is easily tired for a long time.

[0005] To solve the above technical problems, the technical scheme of the application is as follows: a steel part welding device for ship manufacturing, comprising a main support, an annular support is arranged in the main support, two vertical sliding blocks are symmetrically arranged on the two sides of the annular support, one side of the two vertical sliding blocks is fixedly connected with the outer arc surface of the annular support, two vertical sliding rails are symmetrically arranged on the two sides of the annular support, the two vertical sliding rails are matched with the two vertical sliding blocks, a horizontal sliding block is fixedly connected to one side of the vertical sliding rail, two sliding rails are arranged on the two sides of the inner wall of the main support, the two horizontal sliding blocks are matched with the main support, and a scale mark is arranged on the top of the vertical sliding rail.

[0006] Preferably, the inner wall of the annular bracket is provided with four main ball joints in an annular array. One end of each of the four main ball joints is adapted to the inner wall of the annular bracket, and the other end of each of the four main ball joints is provided with a secondary ball joint. One end of each of the four secondary ball joints is slidably connected to the inner wall of the other end of the main ball joint. The annular bracket is provided with a secondary bracket inside, and the other ends of each of the four secondary ball joints are adapted to the secondary bracket.

[0007] Preferably, fastening bolts are provided on both sides of the sub-support, one end of the fastening bolt passes through one side of the sub-support and extends into the interior, and the fastening bolt is threadedly connected to the sub-support.

[0008] Preferably, the annular bracket is provided with handles on both sides, and roller brackets are provided at the top and bottom of the back of the two handles, with rollers provided at the bottom and top of the roller brackets.

[0009] Preferably, push rods are provided at the top and bottom of the back of the handle. One end of the push rod is slidably connected to the inner wall of the handle, and the other end of the push rod is fixedly connected to a push plate. A spring is provided on the outside of the push rod, and the spring is adapted to the push rod. A magnet is provided on the back of the push plate.

[0013] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0014] (1) The device adopts a magnetic adsorption mechanism and a roller movement scheme. Its free adsorption feature is suitable for welding work on various irregular surfaces. When the operator is suspended outside the hull to perform welding operations, he / she does not have to worry about the swaying caused by outdoor wind or his / her own movement affecting the welding. At the same time, when welding inside, especially when welding the top, the operator does not need to hold the welding gun for a long time. It can be freely adsorbed on the top, which greatly reduces the operator's workload. Since the operator does not need to spend extra manpower to hold the welding gun for a long time, the welding process can be more refined, which further improves the work efficiency. The device has a simple structure and light weight, making it particularly suitable for operators to carry and move.

[0015] (2) The damping universal structure composed of the main ball joint and the auxiliary ball joint solves the stability problem during welding. It reduces the difficulty for operators to maintain balance and weld in a narrow space, and also lowers the operating threshold, so that novices can quickly get started and become proficient. This greatly reduces the demand gap for technical personnel in employers. The structure with built-in sunshade largely solves the cumbersome steps of operators having to frequently put on and take off sunshade masks in the dark environment of the narrow space inside the ship. There is no need to wear a mask, which not only facilitates free movement inside the ship but also ensures the protection of personnel's eyes. Attached Figure Description

The annular support 14 is provided with a secondary support 22 inside, and the other ends of each of the four secondary ball joints 16 are adapted to the secondary support 22.

[0030] Fastening bolts 17 are provided on both sides of the sub-support 22. One end of the fastening bolt 17 passes through one side of the sub-support 22 and extends into the interior. The fastening bolt 17 is threadedly connected to the sub-support 22.

[0031] Handles 7 are provided on both sides of the ring bracket 14. Roller brackets 18 are provided on the top and bottom of the back of the two handles 7. Rollers 4 are provided on the bottom and top of the roller brackets 18.

[0032] Push rods 10 are provided at the top and bottom of the back of the handle 7. One end of the push rod 10 is slidably connected to the inner wall of the handle 7, and the other end of the push rod 10 is fixedly connected to the push plate 2. A spring 5 is provided on the outside of the push rod 10, and the spring 5 is adapted to the push rod 10. A magnet 13 is provided on the back of the push plate 2.

[0033] A pull rod 3 is provided on the front of the push plate 2. One end of the pull rod 3 is rotatably connected to the front of the push plate 2. A handle 6 is provided on the other end of the pull rod 3. The back of the handle 6 is rotatably connected to the other end of the pull rod 3. A handle bracket 21 is provided on the top of the handle 6. The top of the handle 6 is rotatably connected to the handle bracket 21. The front of the handle bracket 21 is fixedly connected to the back of the handle 7.

[0034] The main support 1 has a welding torch handle 8 on its front side, and a welding torch head 11 is fixedly connected to the top of the welding torch handle 8. The welding torch head 11 is compatible with the secondary support 22 and the fastening bolt 17.

[0035] A light-shielding mirror 9 is provided on the front of the ring bracket 14. The light-shielding mirror 9 is symmetrically arranged and can be flipped open.

[0036] The working principle and usage process of this invention: Before use, the operator needs to insert the welding torch head 11 into the sub-support 22, then tighten the fastening bolt 17 to fix the welding torch head 11 at the sub-support 22. Then, hold the handle 7 and move the entire structure to the position to be welded, aligning the welding torch head 11 with the weld seam, and then push it forward so that the roller 4 and magnet 13 are completely in contact with the steel surface to be welded. After ensuring alignment, the operator can turn on the welding torch to weld. Due to the universal structure composed of the main ball joint 15 and the sub-ball joint 16, the welding torch head can be rotated within a certain range. At the same time, the structure has a certain damping, ensuring that beginners with lower skill levels can still perform welding work relatively stably. The universal structure also facilitates the use of welding methods such as fish scale welding. The light shield 9 on the front of the ring support 14 can... To prevent the strong light generated during welding from harming the operator's eyes, the vertical slide rail 12 allows the operator to adjust the welding distance normally according to the scale 23 when welding on curved or uneven surfaces. The horizontal slide rail of the main support 1 can ensure stable horizontal movement for welding without moving the main structure. When the horizontal slide rail's travel is insufficient, the operator holds the handle 7 and pulls the handle 6, causing the handle 6 to drive the push plate 2 to move vertically upward through the pull rod 3. At this time, the spring 5 contracts, causing the magnet 13 at the bottom of the push plate 2 to detach from the welding surface, thereby allowing the entire structure to move under the action of the roller 4. When it moves to the next welding area, the handle 6 is released, and the push plate 2 is pushed in the opposite direction under the action of the spring 5, causing the magnet 13 to re-adhere to the surface of the welded steel, achieving a stable effect and continuing the welding operation.
