The patent discloses a flange body welding device for flange production, specifically relates to the field of welding devices, including a support base, the cross-section of the support base is set in a "Z" shape, and a connecting disc is welded on the top side of the support base.

A plurality of threaded pins are installed inside the driving connecting plate for rotation. The patent is set in a meshing state between the center gear and the four groups of linkage gear groups. A linkage gear located at the edge of the driving connecting plate is sleeved on the end of the threaded pin, thereby prompting the four groups of threaded pins to rotate in the same direction.

[0014] The present invention provides a flange body welding device for flange production, which has the following beneficial effects: (1) The invention, through the setting of the clamping device, places the flange body between the fixed frames, and moves the three clamping rods toward the center of the fixed frame through the round rod, brake block, rotating sleeve, fixed sleeve and auxiliary sleeve to realize the positioning and clamping of the flange body. Through precise clamping and positioning, the stability of welding can be ensured, and the problem of clamping shaking can be avoided, thereby improving production efficiency and ensuring production effect. This method can realize the clamping of flanges with different radii, simplifying the operation process and improving work efficiency. The rotation of the round rod is limited by the limiting wheel and the positioning rod, that is, the reversal of the round rod is prevented.

[0015] (2) The invention, through the setting of auxiliary devices, after the flange body and the pipe are clamped, the pipe is brought into contact with the inner wall of the flange body by rotating the first motor, the rotating shaft, the placing frame and the limiting rod. During the welding process, the pipe may move due to various reasons. The limiting rod can effectively prevent such movement and ensure the alignment accuracy of the pipe and the flange body. At this time, the butt joint is welded by the welding arm. After the welding part is completed, the rotation of the pipe drives the flange body to rotate, that is, the butt joint is rotated. The irregular parts are removed by rotating the second motor and the grinding roller, so that the weld surface is smooth, the risk of fatigue damage is reduced, and the service life of the pipe is extended. When the pipe with a larger radius contacts the grinding roller, the grinding roller will be driven to move downward. In this way, the grinding roller can be adapted to each other, so that when facing pipes with different radii, it can be adjusted without the help of external force, thereby improving the work efficiency of the operator.

[0016] (3) The invention, through the setting of the collecting device, generates suction in the slag suction pipe through the operation of the exhaust fan during welding, and strengthens it through the air amplifier, so that the welding slag after grinding by the grinding roller is sucked into the slag suction pipe to prevent the welding slag from splashing everywhere, and is transported to the collection basket through the telescopic pipe. The slag suction pipe is driven to move by the connecting rod, the connecting button, and the elastic telescopic rod, so that the effective position of the slag suction pipe can be adjusted when facing pipes with different radii. When the collection basket needs to be processed, it is disengaged from the positioning groove by the plug block, and the collection basket is taken out at this time. When the collection basket is installed, it is fixed by the plug block, the No. 4 spring, and the positioning groove, so that the collection basket can be quickly installed and disassembled. The quickly disassembled collection basket can easily pour out the collected welding slag for cleaning. At the same time, if the collection basket is damaged or worn, it can also be quickly replaced to ensure the smooth progress of the welding work. BRIEF DESCRIPTION OF THE DRAWINGS
