[0002] Valves are control components in fluid conveying systems and have functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shut-off valves to various valves used in extremely complex automatic control systems. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves, chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, duplex steel valves, plastic valves, non-standard customized valves, etc. according to their materials.

[0033] Working principle:

[0034] When clamping and positioning the circular valve air cylinder to be welded, first, the two valve air cylinders are placed on the two welding positioning mechanisms 4 respectively; then, the servo motor 3 414 is started to drive the screw 413 to rotate; the screw 413 and the inner screw plate 412 form a spiral transmission, so that the inner screw plate 412 moves along the screw 413 in the vertical groove 410; this action is linked to the side frame rod 1 416 and the side frame rod 2 417 through the load-bearing rod 411 to adjust the height, and then the angles of the clamping frame 1 418 and the clamping frame 2 419 are adjusted to overlap, so as to accurately position the circular valve air cylinder;

[0035] In addition, the distance between the two welding positioning mechanisms 4 can be adjusted according to the length of the center valve air cylinder; to achieve this adjustment, the servo motor 6 is started to drive the bidirectional screw rod 5 to rotate; the rotation of the bidirectional screw rod 5 transmits the load-bearing moving block 401 through the screw hole, so that the load-bearing moving block 401 moves along the bidirectional screw rod 5 on the inner side of the adjustment slot frame 1, thereby driving the two welding positioning mechanisms 4 to adjust the distance;

[0036] Finally, according to the welding angle requirement of the valve air cylinder, the annular angle of the welding positioning mechanism 4 that clamps the circular valve air cylinder is adjusted; this adjustment process is achieved by starting the servo motor 2 407. After the motor is started, the worm 406 is driven to rotate, and the worm 406 is engaged with the worm wheel 405, thereby driving the shaft body 404 to rotate in the shaft hole 403; this action adjusts the angle of the mounting frame 408 through the shaft hole 403, so as to facilitate the precise adjustment of the annular angle after the circular valve air cylinder on the welding positioning mechanism 4 is clamped; during the entire operation process, the various components work together to ensure that the clamping and positioning of the valve air cylinder are both accurate and stable; the precise control of the servo motor 3 414 ensures that the clamping frame 1 418 and the clamping frame 2 419 can be accurately overlapped, thereby firmly fixing the valve air cylinder; at the same time, the combination of the servo motor 1 6 and the bidirectional screw 5 allows the distance between the two welding positioning mechanisms 4 to be flexibly adjusted to accommodate valve air cylinders of different lengths.
