Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding equipment technology, specifically a novel butterfly valve positioning welding device. Background Technology
[0002] A butterfly valve, also known as a flap valve, is a simple regulating valve used for on / off control of low-pressure pipeline media. A butterfly valve is characterized by a disc-shaped closing element (valve disc or butterfly plate) that rotates around a valve shaft to open and close. Butterfly valves can control the flow of various types of fluids, including air, water, steam, corrosive media, mud, oil, liquid metals, and radioactive media. They primarily function as shut-off and throttling devices in pipelines. The butterfly valve's opening and closing element is a disc-shaped butterfly plate that rotates around its own axis within the valve body to achieve opening, closing, or regulation. Currently, the welding process between the flange and valve body in butterfly valve manufacturing is quite cumbersome, making it difficult to quickly and concentrically position the valve body and butterfly valve. Furthermore, the welding process requires manual adjustment of the welding position by the operator, hindering convenient welding operations.
[0003] For example, the utility model patent with authorization announcement number CN218426575U discloses a welding positioning device for a butterfly valve flange. This device fixes the base of the movable block to the top surface of the slider, slides the wall surface of the slider to the inside of the limiting groove, thereby allowing the movable block to be pushed on the top surface of the workbench. The rotating rod surface of the workpiece positioning frame is rotatably connected to the inside of the movable block. An anti-slip pad is set on the inner wall of the workpiece positioning frame, and then the wall surface of the spiral rod is threaded to the inside of the workpiece positioning frame. When the spiral rod is rotated, the workpiece to be welded is clamped and fixed inside the workpiece positioning frame, thereby positioning the workpiece to be welded.
[0004] However, in actual use, the device requires manual positioning, which is cumbersome, reduces processing efficiency, and cannot adequately meet production needs. Summary of the Invention

A clamping groove for clamping a flange is opened on the opposite side of the rotating clamping plate, and a clamping groove for clamping a valve cylinder is also opened on the opposite side of the rotating clamping plate.
[0011] As a preferred embodiment, both the first clamping groove and the second clamping groove are arc-shaped grooves.
[0012] As a preferred embodiment, the first clamping groove is located on the side of the lower end of the rotating clamping plate near the center of the welding table, and the second clamping groove is located on the side of the lower end of the rotating clamping plate away from the center of the welding table.
[0013] As a preferred embodiment, the welding mechanism includes a welding electric cylinder mounted on the upper end of the welding frame.

A pair of welding guns are installed on both sides of the welding slide. A welding motor is also installed at the end of the welding lifting seat. The output end of the welding motor is drivenly connected to the shaft end of the welding screw.
[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: The valve cylinder is placed on the placement mechanism, then fixed by the right-side adjustment mechanism in conjunction with the rotation mechanism. Next, the flange is fixed by the left-side rotation mechanism. Then, the flange is moved closer to the left side of the valve cylinder by the adjustment mechanism. Welding is then performed by the welding mechanism. After welding at this point, the flange and valve cylinder are rotated by the rotation mechanism, allowing welding to be performed at different points, thus completing the welding of the left flange. The valve cylinder is then fixed by the left-side rotation mechanism, and another flange is fixed by the right-side rotation mechanism. Repeating the above operations completes the welding of the right flange. This utility model has a reasonable structure, enabling automatic positioning and rotation of the butterfly valve, effectively improving processing efficiency and better meeting usage requirements.

[0023] The working principle of this utility model is as follows: In specific use, the valve cylinder is placed on the placement mechanism 4, and then the valve cylinder is fixed by the adjustment mechanism 2 on the right and the rotation mechanism 3. Then, the flange is fixed by the rotation mechanism 3 on the left. Then, the flange is moved close to the left side of the valve cylinder by the adjustment mechanism 2. Then, welding is performed by the welding mechanism 5. After the welding work at this point is completed, the flange and valve cylinder are rotated by the rotation mechanism 3. Then, welding can be performed at different points, thereby completing the welding work of the left flange. Then, the valve cylinder is fixed by the rotation mechanism 3 on the left. Then, the other flange is fixed by the rotation mechanism 3 on the right. Repeat the above operation to complete the welding work of the right flange.
[0024] As a further embodiment, the placement mechanism 4 includes a placement frame 41 mounted on the welding table 1.

[0027] The working principle of the adjustment mechanism 2 is as follows: During adjustment, the adjustment motor 22 is started, and the adjustment screw 23 is rotated by the adjustment motor 22, thereby realizing the movement of the adjustment seat 24, thereby realizing the adjustment of the position of the valve tube or flange, making it convenient to put the flange and the valve tube together, which facilitates welding work.
[0028] As a further embodiment, the rotating mechanism 3 includes a turntable 32 rotatably mounted inside the adjusting seat 24. A rotating motor 31 is also mounted on the outside of the adjusting seat 24. The output end of the rotating motor 31 is drivenly connected to the shaft end of the turntable 32.
