Description

Technical Field

[0001] This invention relates to the field of valve welding technology, and in particular to a welding apparatus for multi-way valves. Background Technology

[0002] A multi-way valve is a valve capable of controlling multiple fluid channels or multiple fluid paths. This type of valve is designed to allow simultaneous or separate control of different fluid flows as needed, thereby enabling fluid distribution, switching, or regulation among multiple pipes or devices. Multi-way valves are commonly used in systems requiring multi-channel fluid control, such as liquid distribution, gas flow, and energy management. In the manufacturing of multi-way valves, automatic or semi-automatic electric arc welding equipment is commonly used to improve welding efficiency. However, multi-way valves have multiple connecting pipes, requiring accurate alignment before welding and welding in the connection area. Existing processing methods heavily rely on manual alignment, and the multiple pipes necessitate multiple clamping operations for the valve body, reducing production efficiency. Therefore, this invention proposes a welding device that can weld multi-way valves, reducing the number of valve body clamping operations, achieving accurate alignment, and decreasing reliance on manual labor.

An expansion rubber ring 13 is provided on the docking transmission part 24 and is connected to the airflow transmission box 22.

[0031] Operating principle: The valve body is positioned and installed using the positioning mechanism 1. This is achieved by using the clamping electric cylinder 33 to control the clamping plate 34 for positioning and fixation. The angle motor 28 operates, causing the angle electric cylinder 30 to rotate, thus adjusting the valve body angle. During valve body angle adjustment, the signal transmitter and receiver 6 is moved to the inside of the processing ring 2 by the control electric cylinder 5. The signal transmitters and receivers 6 on both sides of the processing ring 2 transmit and receive signals to adjust the valve body angle. By reciprocating the adjustment of the valve body angle, the valve body may obstruct or deviate from the signal transmission and reception path. By analyzing the angle of rotation, the accurate docking angle of the valve body can be determined.

[0032] Furthermore, the positioning mechanism one is located at the bottom of the processing ring 2 to mate with the valve body, and the positioning mechanism two is located at the top of the processing ring 2 to position and install the pipeline on the positioning mechanism two. That is, the clamping plate two 49 is positioned and fixed by the clamping electric cylinder two 48. During installation, the deflection seat 39 can be deflected by the deflection motor 38 so that the clamping plate two 49 faces outward, which facilitates the positioning and installation of the pipeline. Then, the installation seat 41 is moved by the positioning electric cylinder 40 to move the pipeline onto the valve body to achieve mating. Furthermore, the position seat 46 is moved by the welding position electric cylinder 45, and the welding arm 47 performs welding in the mating area. The welding angle motor 42 can rotate the welding turntable 44 to adjust the position of the welding arm 47 and achieve full-area welding.

[0033] After the welding of the top of the valve body is completed, the transfer motor 2 36 operates, causing the transfer seat 2 35 to move on the processing ring 2, that is, to both sides of the valve body. Through the above process, the pipe welding is performed on both sides of the valve body. Finally, the positioning mechanism 2 positions and fixes the valve body on the side or top of the valve body. The transfer motor 26 on the positioning mechanism 1 operates, causing the transfer seat 25 to move, that is, to offset the bottom area of ​​the valve body. The valve body is positioned and fixed on the side of the valve body. Then the positioning mechanism 2 moves to the bottom of the valve body. Through the above process, the final pipe is welded to the valve body.

[0034] When motor 3 operates, lead screw 4 rotates, and slide 7 moves to both sides of the valve body. Control cylinder 3 11 controls the movement of mating sealing part 12, which aligns with the pipes on both sides of the valve body. Airflow is transmitted through airflow transmission box 19, causing the expansion rubber ring 13 to expand, thus sealing the pipes. The valve is then moved to the outside of processing ring 2. Dating cylinder 1 20 controls mating sealing part 21 to align with the bottom of the valve. Airflow transmission box 19 transmits airflow, and the expansion rubber ring 13 on mating sealing part 21 also expands, achieving pipe sealing. Dating cylinder 2 23 controls mating transmission part 24 to align with the top of the valve. Airflow transmission box 2 22 transmits airflow to the inside of the valve, thereby checking for leaks in the welding area. Specifically, control cylinder 2 8 controls the movement of inspection mounting plate 9, motor 2 14 controls the deflection of rotating ring 15 to surround the welding area, and motor 3 17 operates, causing inner ring 16 to rotate. The airflow sensor inside inner ring 16 analyzes and provides feedback on airflow leakage in the welding area.
