Description

Technical Field

[0001] This utility model relates to a tooling for adjusting the extension height of the flange of the end cap assembly connecting pipe. Background Technology

[0002] In industrial production, especially in the manufacturing of pressure vessels, chemical equipment, and piping systems, the welding of end cap assemblies to butt flanges is a crucial step. End cap assemblies are an important part of the pressure vessel or pipeline terminal, while butt flanges are the key interface for connecting different pipelines or equipment.

[0003] Traditional end cap assembly butt joints are supported by temporary fixtures using nut welding. Due to the lack of precise positioning and clamping devices, operators find it difficult to ensure accurate alignment between the butt flange and the end cap assembly shell, resulting in unstable welding quality. In view of this, this utility model proposes a fixture for the flange extension height of the end cap assembly butt joint to solve the above problems. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example:

[0035] like Figure 1-9 As shown, this embodiment proposes a tooling for the extension height of the flange of the end cap assembly connecting pipe, including a base plate 10, the base plate 10 is provided with multiple sets of universal wheels 11, and a support plate 20 is provided on the base plate 10;

[0036] The support plate 20 is provided with a lifting plate 30 that can move up and down. The lifting plate 30 is provided with two sets of adjusting guide rails 31. The adjusting guide rails 31 are arranged along the long side of the lifting plate 30. Two sets of adjusting plates 40 are arranged between the two sets of adjusting guide rails 31. The adjusting plates 40 are provided with clamping rods 50. The adjusting plates 40 move towards the center of the lifting plate 30 on the adjusting guide rails 31, so that the two sets of clamping rods 50 wrap around the outer wall of the connecting flange pipe 60 for clamping.

[0037] In this embodiment, when the flange tube 60 needs to be welded to the shell of the head assembly, the adjusting plate 40 is moved on the adjusting guide rail 31 and moves towards the center of the lifting plate 30 until the two sets of clamping rods 50 wrap around the outer wall of the flange tube 60. The flange tube 60 is held by the two sets of clamping rods 50, so that the flange tube 60 is kept stable. Then the lifting plate 30 is raised and lowered on the support plate 20 to adjust the height of the flange tube 60 until the flange tube 60 contacts and aligns with the shell of the head assembly. Then the welding process can be carried out.

[0038] By adjusting the displacement of the plate 40 on the adjusting guide rail 31, the clamping rod 50 can accurately wrap around the outer wall of the mating flange tube 60, ensuring that the mating flange tube 60 is accurately aligned with the head assembly shell before welding, thereby improving the welding accuracy and allowing the mating flange tube 60 to remain stable during the welding process, reducing welding defects caused by the instability of the mating flange tube 60 and improving the welding quality.

[0039] The vertical displacement function of the lifting plate 30 allows the operator to adjust the height of the docking flange pipe 60 according to actual needs to achieve a perfect docking with the head assembly shell. This increases the applicability and flexibility of the tooling, simplifies the docking process between the docking flange pipe 60 and the head assembly shell, reduces the time and labor intensity of manual adjustment, and thus improves the overall work efficiency.

[0040] Specifically, the adjustment plate 40 is provided with four sets of adjustment sliders 32, with each pair of adjustment sliders 32 arranged symmetrically, and the adjustment sliders 32 are adapted to the adjustment guide rail 31;

[0041] The adjustment plate 40 is slidably mounted on the lifting plate 30 through the sliding cooperation between the adjustment slider 32 and the adjustment guide rail 31.

[0042] In this embodiment, when the position of the adjustment plate 40 needs to be adjusted, the sliding cooperation between the adjustment slider 32 and the adjustment guide rail 31 allows the adjustment plate 40 to smoothly slide and adjust its position on the lifting plate 30.

[0043] Specifically, two sets of lifting guide rails 21 are symmetrically arranged on the support plate 20, and the lifting guide rails 21 are arranged along the long side of the support plate 20.

[0044] The lifting guide rail 21 is provided with two sets of lifting sliders 23, and the lifting plate 30 is connected to four sets of lifting sliders 23.

[0045] In this embodiment, the sliding cooperation between the lifting slider 23 and the lifting guide rail 21 allows the lifting plate 30 to slide on the support plate 20 for lifting and lowering, so as to adjust the height of the docking flange pipe 60.

[0046] Specifically, the support plate 20 is also provided with a rack 22, which is arranged parallel to the lifting guide rail 21;

[0047] The bottom of the lifting plate 30 is provided with a rotatable gear 70, which meshes with the rack 22.

[0048] Specifically, the bottom of the lifting plate 30 is provided with two sets of mounting plates 73;

[0049] The gear 70 is provided with a rotating rod 72, which is rotatably disposed between two sets of mounting plates 73, and a rotating handwheel 71 is provided on the rotating rod 72.

[0050] In this embodiment, when the height of the lifting plate 30 is adjusted, the rotating handwheel 71 drives the rotating rod 72 to rotate, thereby driving the gear 70 to rotate. Through the meshing of the gear 70 and the rack 22, the mounting plate 73 is driven to rise or fall, thereby driving the lifting plate 30 to rise or fall.

[0051] Of course, a scale can be engraved on rack 22 to ensure the accuracy of lifting.

[0052] Specifically, a fixing plate 76 is provided at the bottom of the two sets of mounting plates 73, and a threaded screw 78 is provided on the fixing plate 76, the screw 78 passing through the fixing plate 76;

[0053] A limiting plate 74 is provided on the screw 78, and the limiting plate 74 is disposed between two sets of mounting plates 73.

[0054] In this embodiment, when the gear 70 does not need to rotate, the screw 78 engages with the fixed plate 76 to raise the limiting plate 74 to contact the gear 70, thereby preventing the gear 70 from rotating and affecting the stability of the docking flange pipe 60 after height adjustment.

[0055] Specifically, a hexagonal actuating block 77 is provided on the screw 78, and the hexagonal actuating block 77 is located at the end away from the limiting plate 74;

[0056] A rubber pad 75 is provided on the limiting plate 74, and the rubber pad 75 is fixedly connected to the limiting plate 74.

[0057] In this embodiment, the hexagonal toggle block 77 facilitates the rotation of the screw 78, and the rubber pad 75 effectively increases friction, making it easier to restrict the gear 70.

[0058] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
