[0014] A method for using an anti-corrosion casing port welding device comprises the following steps:

[0015] S1. The operator first places the anti-corrosion pipe body on the bracket plate, and the three-way pipe body is sleeved on the hollow plate and the hollow column. The vertical rack drives the horizontal gear to rotate, and the rotation of the horizontal gear drives the horizontal axis and the two clamping plates to swing. When the vertical roller moves to the long horizontal groove on the guide groove of the guide frame, the two clamping plates swing and cooperate with the bracket plate to clamp and fix the anti-corrosion pipe body;

[0016] S2. After the bracket plate moves, it will contact one side of the limit frame, and the guide roller will also contact one side of the lower slide plate. At this time, one end of the anti-corrosion pipe body will contact one end of the three-way pipe body, and the contact point between the anti-corrosion pipe body and the three-way pipe body will move to the three alignment wheels;

[0017] S3. Under the action of the three arc grooves on the arc groove wheel, the three alignment rollers, the three alignment sliders and the three alignment wheels will move away from each other, and the three alignment wheels will contact the inner side walls of the anti-corrosion pipe body and the tee pipe body. After the anti-corrosion pipe body and the tee pipe body are aligned, the operator welds the contact part of the anti-corrosion pipe body and the tee pipe body. The three alignment wheels will push the anti-corrosion pipe body and the tee pipe body to move, so that the axes of the anti-corrosion pipe body and the tee pipe body coincide, and the operator can weld the anti-corrosion pipe body and the tee pipe body;

[0018] S4. When the bracket plate is separated from the limit frame, under the action of the limit spring, the limit frame and the limit roller drive the three-way pipe body and the anti-corrosion pipe body to move on the bracket plate, and then the operator swings the welded anti-corrosion pipe body and the three-way pipe body along the hollow plate and the hollow column, and the guide beads play a guiding role. After the anti-corrosion pipe body is separated from the bracket plate, the operator can take the welded anti-corrosion pipe body and the three-way pipe body out of the hollow plate and the hollow column.

[0019] The beneficial effects of the present invention are: 1. The three alignment wheels will push the anti-corrosion pipe body and the three-way pipe body to move, so that the axes of the anti-corrosion pipe body and the three-way pipe body coincide, thereby enabling the anti-corrosion pipe body and the three-way pipe body to be more accurately aligned, avoiding relative displacement between the anti-corrosion pipe body and the three-way pipe body during welding, thereby improving the quality and efficiency of welding the anti-corrosion pipe body and the three-way pipe body.

[0020] 2. The positioning frame can be used to more conveniently and accurately position the anti-corrosion pipe body, so as to improve the accuracy of the placement of the anti-corrosion pipe body, thereby improving the efficiency of the placement of the anti-corrosion pipe body, thereby improving the efficiency of the welding of the anti-corrosion pipe body and the tee pipe body.

[0021] 3. The position of the tee pipe body is corrected and fixed by the limit frame and the sliding plate, so that the position of the tee pipe body is more accurate, so that the anti-corrosion pipe body can be aligned with the tee pipe body more accurately, further avoiding relative displacement between the anti-corrosion pipe body and the tee pipe body during welding, thereby further improving the quality and efficiency of welding the anti-corrosion pipe body and the tee pipe body.
