[0015] Beneficial Effects

[0016] The present invention provides a calibration device for anti-corrosion pipeline flange welding. Compared with the prior art, it has the following beneficial effects:

[0017] 1. The calibration device for welding anti-corrosion pipeline flanges starts a driving motor to drive the driving disk to rotate counterclockwise. The rotation of the driving disk causes one end of the connecting rod to rotate on the top of the driving disk, causing the other end of the connecting rod to rotate on one side of the sliding plate, thereby causing the three groups of sliding plates to slide toward the center synchronously, causing the sliding plates to slide on the surface of the positioning slide rails. The sliding of the sliding plates drives the sliding blocks and the positioning blocks to slide synchronously, and the pipeline flanges are calibrated and positioned by the three groups of positioning blocks, so that the pipeline flanges remain stable. By providing a calibration mechanism, the three groups of positioning blocks can be synchronously adjusted under the drive of the driving motor, so that the pipeline flanges placed on the top of the base are positioned and calibrated by the three groups of positioning blocks, and because the positions of the three groups of positioning blocks can be flexibly adjusted synchronously, positioning and calibration can be performed for pipeline flanges of different sizes to keep them stable, thereby improving the stability during the subsequent welding of the anti-corrosion pipelines and pipeline flanges.

[0018] 2. The calibration device for anti-corrosion pipe flange welding drives the piston rod and the movable tooth plate to slide synchronously to the rear side by starting the clamping cylinder. The sliding of the movable tooth plate causes the transmission gears on both sides to rotate synchronously and in opposite directions. The rotation of the transmission gear drives the linkage gears on both sides to rotate synchronously. The rotation of the linkage gear causes the connecting tooth plates on both sides to slide synchronously to the opposite sides, so that the connecting tooth plates slide on the surface of the guide rails. The sliding of the connecting tooth plates drives the clamping plates on both sides to slide synchronously. The anti-corrosion pipes are clamped and calibrated by the clamping plates. By providing a clamping mechanism, the distance between the two sets of clamping plates can be flexibly adjusted under the drive of the clamping cylinder. Therefore, the two sets of clamping plates can be used to clamp and calibrate anti-corrosion pipes of different sizes, thereby maintaining the stability of the anti-corrosion pipes during welding.

[0019] 3. The calibration device for anti-corrosion pipe flange welding is provided with a lifting assembly. Driven by a lifting motor, the height of the clamping plate can be flexibly adjusted, so that the clamping mechanism can be suitable for anti-corrosion pipes of different heights. When clamping and calibrating the anti-corrosion pipes, it can be flexibly adjusted to a suitable clamping position to achieve the best clamping calibration effect. BRIEF DESCRIPTION OF THE DRAWINGS
