Description

Technical Field

[0001] This invention belongs to the technical field of flange tooling, specifically relating to a precise positioning tooling for flange pipe installation. Background Technology

[0002] A flange, also called a flange plate or flange, is a part used to connect shafts, pipe ends, or on equipment inlets and outlets for connecting two pieces of equipment.

[0003] When flanged pipes need to be connected to curved surfaces, to facilitate the operation of workers, they are usually lifted by a hanger or crane, and then bolt adjusting seats are spot welded around the perimeter of the flanged pipe. The surface of the flange is then leveled by the hanger and bolt adjusting seats before welding. After welding, the bolt adjusting seats need to be cut off with an angle grinder. This method is time-consuming and labor-intensive, requiring multiple steps to complete the welding. The leveling of the flange is also very difficult, so a flange tooling that can be precisely positioned is needed. Summary of the Invention

[0004] This invention proposes a precision positioning fixture for flange pipe installation, comprising clamping plates, screws, locking nuts, and adjusting bolts. The clamping plates are square in shape, with a beveled corner at one corner and a right-angled corner symmetrical to the beveled corner. An upper screw hole is located on the right side of the right-angled corner, and a reinforcing block is located at the bottom left side of the right-angled corner. A lower screw hole is horizontally penetrating through the center of the reinforcing block, with a screw installed in both the upper and lower screw holes. Four clamping plates are arranged in a circumferential array and connected to each other by screws. Locking nuts are located at both ends of the screws, and adjusting bolts are penetrating through the top surface of the clamping plates. Different sized flange pipes can be clamped by adjusting the clamping plates above the screws, and the flange pipes can be locked in place by tightening the locking bolts inwards.

[0005] Furthermore, the beveled surface is provided with longitudinal anti-slip strips to increase the clamping force of the clamping plate on the outside of the flange fitting, preventing loosening due to unstable clamping.

[0006] Furthermore, the adjusting bolt is installed on the clamp plate through a threaded hole, which allows for precise adjustment of the flange height by rotating the adjusting bolt.

[0007] Furthermore, the adjusting bolt is an internal hex bolt, which allows for easy adjustment of the bolt's height using a hex wrench, making it convenient to use.

[0008] Furthermore, the top surface of the clamp is equipped with an angled level, which allows for intuitive adjustment of the flange pipe's levelness.

[0009] Beneficial effects:

[0010] This invention uses a clamping plate above a screw to clamp flanges of different sizes, and tightens the locking bolts inward to lock the flanges, increasing the clamping force of the clamping plate on the outside of the flange fittings and preventing loosening due to unstable clamping. It also allows for precise adjustment of the flange height by rotating the adjusting bolts, and the height of the adjusting bolts can be easily adjusted directly with a hex wrench, making it convenient to use.

[0014] To enhance understanding of the present invention, the invention will be further described in detail below with reference to embodiments and accompanying drawings. These embodiments are only for explaining the invention and do not constitute a limitation on the scope of protection of the invention.

[0015] Implementation example:

[0016] A precision positioning fixture for flange pipe installation includes clamping plates, screws, locking nuts, and adjusting bolts. The clamping plates are square in shape, with a beveled corner at one corner and a right-angled corner symmetrical to the beveled corner. An upper screw hole is located on the right side of the right-angled corner, and a reinforcing block is located at the bottom left side of the right-angled corner. A lower screw hole is horizontally penetrating the center of the reinforcing block. A screw is installed in both the upper and lower screw holes. Four clamping plates are arranged in a circumferential array, connected to each other by screws. Locking nuts are located at both ends of the screws, and adjusting bolts penetrate the top surface of the clamping plates.

[0017] like Figure 1 , 2 As shown;

[0018] Loosen the locking nut 5, adjust the spacing between the beveled angles of the clamping plates 3 according to the pipe diameter at the bottom of the flange pipe 2, place the flange pipe 2 into the fixture between the clamps, move the clamping plates 3 inward along the screw 4, so that the beveled angles of the clamping plates 3 are in close contact with the outer side of the flange pipe, and the bottom of the flange is flush with the top surface of the clamping plates 3. Rotate the locking nut 5 to lock the locking nut 5 to the clamping plates 3 through the screw 4, ensuring the stability between the clamping plates 3, the flange pipe 2 and the locking nut 5. This completes the connection between the fixture and the flange pipe.

[0019] When it is necessary to weld flange pipe 2 to installation pipe 1, use a crane or manual labor to place the tooling with flange pipe 2 installed at the position where welding is required, rotate the adjusting bolt 6 to adjust the level of flange pipe 2, and the required level of welding can be visually observed through a spirit level. After the adjustment is completed, the welding work can be completed directly.

[0020] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
