Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to an adjustable fillet welding device. Background Technology

[0002] Ship hull structures are complex with a large number of welds. However, not all welded joints are suitable for automated equipment. Generally, straight welded joints are more conducive to automation, and the longer the welded joint, the better for automation. Currently, the application of automated equipment for butt joints and corner joints in flat welding positions is basically widespread in domestic shipyards. However, during shipbuilding, especially in the group erection workstation, many corner welds cannot meet the basic operating width requirements of automatic corner welders (which cannot be less than 250mm). Therefore, most of these welds are still welded manually.

[0003] like Figure 3 As shown, the fillet weld between the non-watertight rib 1 and the reinforcing member 3 is affected by the presence of a manhole 2 on one side of the non-watertight rib 1, or the distance between the two reinforcing members 3 is less than 250mm, making it impossible to use an automatic fillet welder. Similarly, the welding of the reinforcing ribs on the annular frame of the pipe-tunnel assembly does not meet the requirements of an automatic fillet welder. Manual welding in these areas will result in some welds being of poor quality, leading to a large amount of rework, which is time-consuming, labor-intensive, and affects the production schedule. Therefore, it is necessary to study an adjustable fillet welder to solve the problem of manual welding of welds that are not suitable for automatic fillet welders. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable fillet welding device to solve the problem of manual welding at locations where a semi-automatic fillet welding machine cannot be used for automatic welding, thereby improving welding quality and welding speed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable fillet welding device includes a moving trolley, a fixed base, a left support rod, a left upper open-type cross clamp, a crossbeam, a right upper open-type cross clamp, a right support rod, a welding torch holder, a welding torch, and a T-shaped support base. The fixed base is mounted on the moving trolley. The T-shaped support base is fixedly mounted on the fixed base using fasteners. The lower end of the left support rod is rotatably and vertically movable and fixedly mounted on the T-shaped support base. The upper end of the left support rod is rotatably and vertically movable and fixedly mounted with the left upper open-type cross clamp. The left end of the crossbeam is rotatably and vertically movable. The left and right movable fixed installation is on the upper left open cross-shaped fixing clamp. The right end of the crossbeam rod is rotatable and rotatable and fixed on the upper right open cross-shaped fixing clamp. The upper end of the right support rod is rotatable and rotatable and fixed on the upper right open cross-shaped fixing clamp. A welding gun holder is provided at the lower end of the right support rod, and the welding gun is installed on the welding gun holder. The moving trolley is provided with wheels. A magnet is provided at the lower part of the moving trolley. The moving trolley is provided with a drive motor. Under the magnetic force of the magnet, it is attracted to the non-watertight rib plate and moves.

[0007] The aforementioned adjustable fillet welding device has two support arms on the moving trolley, and each support arm is equipped with a roller at its right end.

[0008] In the aforementioned adjustable fillet welding device, the two support arms are of different lengths, with the front support arm being shorter than the rear support arm along the welding direction.

[0009] The adjustable fillet welding device described above has the same structure for the upper left open cross clamp and the upper right open cross clamp. Both clamps use fasteners to tighten the openings on the two clamps to hold the rod-shaped parts in place.

[0010] This utility model has the following advantages:

[0011] This utility model comprises a right-angle portal frame consisting of a left support rod, a crossbeam, and a right support rod, which are fixedly connected by an open-type cross clamp. The length or height can be adjusted arbitrarily at each turning point. The welding torch is mounted on the right support rod, and a moving trolley drives the welding torch. The moving speed of the moving trolley can be set according to different welding requirements. This utility model is applicable to various types of cross-part welding. For fillet welds in confined spaces or with obstacles, it achieves semi-automatic welding, reducing manual input and labor intensity. It is highly beneficial to improving production efficiency and reducing costs, thus achieving the goal of cost reduction and efficiency improvement. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] This utility model provides an adjustable fillet welding device, such as... Figure 1 As shown, the device includes a mobile trolley section, a gantry section, and a welding torch 16. The gantry section is mounted on the mobile trolley section and moves with the mobile trolley section. The welding torch 16 is mounted on the gantry section.

[0020] The aforementioned mobile trolley includes a mobile trolley 4, wheels 5, magnets 6, support arms 7, rollers 8, and a fixed base 9. The mobile trolley 4 is equipped with a drive motor, wheels 5, magnets 6, support arms 7, rollers 8, and a fixed base 9. The rollers 8 are mounted on the support arms 7, which have two sections, one on each side of the mobile trolley 4. The mobile trolley 4 can be magnetically attached to the structure to be welded and can move at a set speed. It is small in size and weight, making it highly portable.

[0021] The aforementioned gantry frame includes a left support rod 10, a left upper open-type cross clamp 11, a crossbeam 12, a right upper open-type cross clamp 13, a right support rod 14, a welding gun holder 15, and a T-shaped support seat 17; as shown Figure 5 As shown, the upper left open-type cross clamp 11 and the upper right open-type cross clamp 13 have the same structure, both having two mutually perpendicular through holes. A 2mm gap is provided on one side of each through hole. Fastening bolts are used to clamp the left support rod 10, the right support rod 14, and the crossbeam rod 12. The T-shaped support base 17 has the following structure... Figure 4As shown, it is installed on the fixed base 9 using fasteners. There are two in the vertical direction. The lower end of the left support rod 10 is fixedly installed on the T-shaped support base 17, which can be rotated and moved up and down. The lower end of the right support rod 14 is provided with a welding gun base 15, and the welding gun 16 is installed on the welding gun base 15.

[0022] This utility model provides an adjustable fillet welding device, such as... Figure 2 As shown, the roller 8 is pressed against the side of the stiffener 3. Since the two support arms 7 are of different lengths, there is an angle between the moving trolley 4 and the stiffener 3. When the moving trolley 4 moves under the drive of its own drive motor, the above-mentioned angle can ensure that the roller 8 is always pressed against the stiffener 3, thereby ensuring that the welding torch 16 moves along the side of the stiffener 3.

[0023] The adjustable fillet welding device of this utility model works as follows: Before welding, adjust the appropriate current and voltage of the welding machine, place the moving trolley 4 in the accurate position, set its moving speed, fix the welding gun 16 of the welding machine on the welding gun holder 15, adjust the length and angle of the left support rod 10, right support rod 14 and crossbeam 12 according to different welding positions, align the welding gun 16 with the weld seam, and then the automatic welding work can be carried out.

[0024] This utility model discloses an adjustable fillet welding device. In the gantry frame section, the length of each turning point can be adjusted arbitrarily. The left support rod 10 and the right support rod 14 can be adjusted in height or rotated to adjust the angle. This utility model is applicable to various forms of automatic welding of cross parts.
