Especially when facing large-sized pipe fittings, it is difficult to improve the welding efficiency and it occupies a large floor space. Therefore, there is a need in the market for a component that can efficiently and stably complete the welding of pipe fittings to meet the needs of modern industrial production. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a new type of efficient welding assembly for pipe fittings, aiming to improve welding efficiency, ensure welding quality and simplify the operation process.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Now, the present utility model will be further described in detail with reference to the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model. The present utility model is described in detail using structure diagrams and the like. The schematic diagrams are only examples and should not limit the scope of protection of the present utility model here.

[0022] Please refer to Figures 1 to 4 , a high-efficiency welding assembly for pipe fittings, including a horizontally arranged row rail 1 and a tiltable slide 2 movably connected thereto. A support roller set 3 for carrying the pipe fittings to be welded is arranged on the tiltable slide 2;

[0023] A welding mechanism 4 with a fixed position is arranged between the two support roller sets 3. The welding mechanism 4 includes two welding torches 4a with different heights. The welding torch 4a located above is movably arranged on an arc-shaped frame 4b. The arc-shaped frame 4b is in the shape of a quarter circle, and its lower end is connected to an upright frame. The welding torch 4a located below has a fixed position. The welding torch 4a located above is connected to the arc-shaped frame 4b through a sliding seat. The height of the welding torch 4a located above changes as its position on the arc-shaped frame 4b changes. When the welding torch 4a located above moves to the highest position, it is vertically opposite to the welding torch 4a below. During the welding operation, the welding torch 4a located above moves to the highest position, and the support roller set 3 drives the pipe fittings to rotate. The two welding torches 4a each complete a weld bead with half the length.

[0024] Each support roller set 3 includes four roller wheels 3a arranged at the four corners of a rectangle. A synchronous rotating shaft 5 is connected between the two support roller sets 3. The synchronous rotating shaft 5 penetrates through the axles of some of the roller wheels 3a. One of the roller wheels 3a connected to the synchronous rotating shaft 5 is internally provided with a rotating motor, and this roller wheel 3a is the driving power roller wheel. The synchronous rotating shaft 5 is used to keep the roller wheels 3a connected thereto rotating synchronously; the four roller wheels 3a connected by one synchronous rotating shaft 5 come from two support roller sets 3 respectively. Specifically, two roller wheels 3a on the same side in one support roller set 3 are connected to the synchronous rotating shaft 5. Matching tooth grooves are arranged on the outer periphery of the synchronous rotating shaft 5 and the inner periphery of the roller wheels 3a. The roller wheels 3a can linearly translate along the central axis of the synchronous rotating shaft 5. They are movably connected but rotate synchronously. Limit blocks 5a are arranged at both ends of the synchronous rotating shaft 5 with a length exceeding the row rail 1 to prevent it from slipping out of the inner periphery of the roller wheels 3a.

[0025] To achieve convenient unloading after welding, the tiltable slide 2 includes an upper layer plate 2a and a lower layer plate 2b with a variable included angle. The upper layer plate 2a and the lower layer plate 2b are connected by a hinge 2c. The lower layer plate 2b is slidably connected to the row rail 1. The roller wheels 3a are arranged on a rotating shaft fixed on the upper layer plate 2a. Tilting the upper layer plate 2a obliquely upward based on the hinge 2c can tilt the support roller set 3 and quickly unload the welded pipe fittings; the synchronous rotating shaft 5 and the arc-shaped frame 4b are arranged on the same side of the row rail 1. The synchronous rotating shaft 5 and the hinge 2c are respectively located on two opposite sides of the tiltable slide 2. The synchronous rotating shaft 5 and the arc-shaped frame 4b will not interfere with the unloading. When unloading, the welding torch 4a located above slides downward along the arc-shaped frame 4b to make way for the pipe fittings.

[0026] When the high-efficiency welding assembly for pipe fittings of the present utility model is in use, two pipe fittings to be welded are placed on the support roller set 3. The tiltable sliding table 2 is pushed to move towards each other so that the pipe orifices to be welded come into contact. Then, the welding torch 4a located above is moved to the highest position and is vertically opposite to the welding torch 4a located below. While starting the welding machine, the driving power roller is turned on. The support roller set 3 rotates the two pipe fittings synchronously to complete the welding. In this process, each of the two welding torches 4a completes a weld bead of half the length, improving the working efficiency. After the welding is completed, the welding torch 4a located above is lowered, and the upper plate 2a is tilted upwards obliquely based on the hinge 2c, so that the support roller set 3 can be tilted, facilitating the rapid unloading of the welded pipe fittings and improving the working efficiency.

[0027] As mentioned above, only the preferred embodiments of the present utility model are described, but the protection scope of the present utility model is not limited thereto. It should be noted that for those skilled in the art, any changes, modifications or additions made without departing from the concept of the present utility model shall fall within the protection scope of the present utility model.
