Description

Technical Field

[0001] The utility model relates to the technical field of flange installation, in particular to a full-size flange positioning tool. Background Art

[0002] Flanges are parts that connect shafts to each other and are used to connect pipe ends. Traditional flange installation often involves a chaotic operation site, requiring the use of several tools such as a spirit level, square, and hammer for accuracy. Assembling larger flanges requires the use of a crane, which is fraught with uncertainty. Operators may find it difficult due to the lack of accurate positioning and fixing tools, which can also lead to safety hazards during installation. Flanges need to be assembled in a vertical position during installation. There are small holes arranged in a ring on the flange for assembling other components. The overall position and angle of the flange must be accurate, and the two holes at the top of the flange must be horizontal when the flange is placed for better and more accurate assembly. Therefore, a tooling is required to support flanges of different sizes, and the overall levelness of the flange must also be adjustable, and the two holes at the top of the flange must be adjustable to a horizontal position. Therefore, solving this problem is very important. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to propose a full-size flange positioning tool to solve the problems that the existing technology cannot support flanges of different sizes, the overall levelness cannot be adjusted, and the two holes at the top of the flange cannot be adjusted to a horizontal level.

[0004] Based on the above-mentioned purpose, the utility model provides a full-size flange positioning tool, including a portal frame, on which two support frames are arranged for horizontal sliding, and the two support frames move relative to each other or in opposite directions. The two support frames are arranged at intervals on the left and right and the inner top ends are arc-shaped; the support frame includes two front and rear side plates and a bottom plate, and a rolling shaft is rotatably arranged at the bottom end of the adjacent side of the support frame, and the front top end of the support frame is threadedly connected to a clamping shaft that moves back and forth, and the rear end of the clamping shaft extends into the support frame; the rolling shaft is located at the lower inner side of the support frame and is used to support the flange. The surface of the rolling shaft is smooth and contacts with the bottom end of the flange, and the flange is rotatable on the rolling shaft; the four corners of the top end of the portal frame are vertically threadedly connected with threaded adjustment shafts, and the bottom end of the threaded adjustment shaft contacts the ground.

[0005] Preferably, a transverse sliding groove is provided on the top of the portal frame, and a slider is provided at the bottom of the support frame, which is adapted to the sliding groove, and the slider passes downward through the sliding groove and is connected to a threaded block; a threaded shaft is rotatably connected to the two sides of the portal frame, and the threaded shaft has two opposite threads, and the two threaded blocks are respectively provided with threaded holes that match the two opposite threads of the threaded shaft, so that the threaded block is threadedly sleeved on the threaded shaft.
