A lifting plate 8 is slidably installed in the hinge positioning tube 7. A support strip 9 is installed on one side of the lifting plate 8. A fastening screw 10 is installed on one side of the hinge positioning tube 7. The height of the lifting plate 8 is adjusted so that the tops of all the lifting plates 8 are flush, and then the fastening screws 10 are tightened to fasten the lifting plate 8. One end of the screw 10 is pressed tightly against the lifting plate 8 to fix the lifting plate 8 in the hinge positioning tube 7, so that all the support strips 9 are aligned. When in use, the welded door frame is placed on the top of multiple bottom support screws 2, so that the door frame is placed flat on the top of the door frame mounting frame 1, and then the adjusting nut 6 is rotated to make the adjusting nut 6 away from the correction plate 4. Since one side of the adjusting nut 4 is against the door frame mounting frame 1, the correction plate 4 is moved toward the side close to the door frame until it contacts and pushes the door frame to move, so that the side of the door frame where the hinge needs to be welded is close to the side of the hinge positioning tube 7, and then Then rotate the first fastening screw 3 so that one end of the two symmetrical first fastening bolts 3 is pressed tightly against the two sides of the door frame to clamp the door frame. Then unfold the hinge, insert one side of the hinge into the gap between the lifting plate 8 and the door frame and close it to the door frame. The bottom of the hinge contacts the support bar 9, and the hinge is supported and positioned by the support bar 9. Then welding can be performed to connect the hinge to the door frame. Because all the support bars 9 are aligned, the page axis heights of all the hinges are kept consistent and coaxial. After the door frame is removed, the parts of the hinge that are not welded in place can be repaired.

[0028] The door frame is positioned by setting a door frame mounting frame 1, a bottom support screw 2, a first fastening screw 3, a correction plate 4, and a hinge positioning tube 7, and the hinge is positioned by using a lifting plate 8 and a support bar 9, so as to facilitate the welding of the hinge and the door frame, make the hinge axis more coaxial, and thus improve the installation accuracy of the hinge and the welding quality.
