Description

Technical Field

[0001] This utility model relates to the field of welding auxiliary tools, specifically to a clamp for adjusting the bevel of a cylinder section. Background Technology

[0002] When manufacturing equipment with large cylindrical structures, such as deaerators and rotary kilns, these structures are achieved by welding multiple cylindrical sections together to form a single unit. During the welding process, the cylinder is first hoisted onto the slide support, roughly aligning the end faces of the two sections. Then, the end faces to be welded are beveled and adjusted, involving fine-tuning the axial and radial clearances between them. This process requires setting several clamps on the circumference of the cylinder sections on both sides of the gap to be welded. These clamps are used to make segmented fine-tuning of the end faces, thus achieving comprehensive adjustment of the bevel alignment dimensions of the two cylinder sections.

[0003] Currently, there is a lack of integrated clamps when adjusting the bevel alignment of cylinder sections. Therefore, even though the axial and radial clearance adjustment parts follow the principle of selecting adjacent points, and the clamp structures used in the two adjustment processes are highly similar—both are combinations of fixed seats and bolts, differing only in the bolt installation orientation—in actual operation, the axial and radial clearance adjustment clamps must be welded and installed individually, making the operation cumbersome. When installing the clamps, the mounting seat must first be welded to the cylinder section, the misalignment adjusted, and the welding between cylinder sections completed. Then, the clamps must be removed from the cylinder section, and the welded surfaces ground and repaired. However, the mounting seats on existing clamps are all block structures, and the welding range between the mounting seat and the cylinder section is large, making the installation and removal of clamps time-consuming and labor-intensive. This also increases the probability of damaging the cylinder section when separating the welded parts, further complicating the repair work on the welded surfaces. To address these problems, this utility model proposes a clamp for adjusting the bevel alignment of cylinder sections. Utility Model Content

[0004] The purpose of this utility model is to provide a clamp for adjusting the bevel of cylindrical sections in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions: This utility model provides a clamp for adjusting the bevel of a cylindrical section, including a bracket. A support screw is threadedly connected to the bracket and is arranged along the axial direction of the cylindrical section. An axial clearance adjusting component and a support component are threadedly sleeved on the support screw. Radial clearance adjusting components are provided on both sides of the axial clearance adjusting component, and positioning sleeves are provided on both sides of the support component. The radial clearance adjusting component and the support component are connected to the bracket by corresponding adjusting screws.

[0006] As a further optimization of this utility model, both the radial clearance adjusting component and the support component are threaded onto the corresponding adjusting screw, and the adjusting screw is threadedly connected to the bracket.

[0007] As a further optimization of this utility model, the bracket includes two side rods, and the center of the side rods is provided with a protrusion for fixing the two ends of the support screw. Two radial clearance adjustment components are provided on the same side rod.

[0008] As a further optimization of this utility model, the axial clearance adjusting component includes a first adjusting screw sleeve, a connecting sleeve rotatably sleeved on the first adjusting screw sleeve, and a fixed post provided on the connecting sleeve.

[0009] As a further optimization of this utility model, the radial clearance adjusting component includes a second adjusting screw sleeve and a fixed sleeve that is rotatably sleeved on the second adjusting screw sleeve.

[0010] As a further optimization of this utility model, the end of the fixed sleeve away from the bracket protrudes from the end face of the No. 2 adjusting screw sleeve.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a clamp for adjusting the bevel of cylindrical sections, integrating radial and axial clearance adjustment functions required for bevel assembly. Through the cooperation of a bracket, supporting screw, axial clearance adjusting component, radial clearance adjusting component, and adjusting screw, a unified clamp is obtained, simplifying the installation steps. Furthermore, the clamp, through the cooperation of the axial clearance adjusting component, radial clearance adjusting component, supporting component, and positioning sleeve, achieves a distributed spot welding fixing effect, avoiding the inconvenience of disassembly and assembly caused by large-area welding. The clamp can also be quickly removed after use, improving the efficiency of weld removal and repair. Overall, this significantly improves the convenience of adjusting the bevel of cylindrical sections using this clamp. Attached Figure Description

[0014] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0015] Example 1 like Figure 1-5 As shown, the clamp for adjusting the bevel assembly of the cylinder section in this embodiment includes a bracket. A support screw 2 is threadedly connected to the bracket and arranged along the axial direction of the cylinder section. An axial clearance adjusting component 4 and a support component 5 are threadedly sleeved on the support screw 2. Radial clearance adjusting components 7 are provided on both sides of the axial clearance adjusting component 4, and positioning sleeves 6 are provided on both sides of the support component 5. The radial clearance adjusting component 7 and the support component 5 are connected to the bracket by a one-to-one corresponding adjusting screw 8. The radial clearance adjusting component 7, the support screw 2 and the positioning sleeve 6 are all located on the same side of the bracket. Both the radial clearance adjusting component 7 and the support component 5 are threaded onto the corresponding adjusting screw 8, and the adjusting screw 8 is threadedly connected to the bracket. The outer surfaces of the support screw 2, axial clearance adjustment component 4, radial clearance adjustment component 7, and adjustment screw 8 are all machined to a profile that matches the wrench and are compatible with wrenches of the same size.

[0016] The method of using the adjustment clamps for the bevel assembly of the cylindrical section is as follows: The operator holds the bracket and makes the axial clearance adjusting piece 4 and the two radial clearance adjusting pieces 7 fit against the inner wall of one cylindrical section, and the support piece 5 and the two positioning sleeves 6 fit against the inner wall of the other cylindrical section. Then, the axial clearance adjusting piece 4, the radial clearance adjusting piece 7, the support piece 5 and the positioning sleeves 6 are welded and fixed to the corresponding cylindrical sections respectively. This completes the installation of a single clamp. Repeat the above operation to install several clamps on the circumference of the two cylindrical sections. The distribution gap of the clamps does not need to be precisely controlled, just keep it roughly uniform. After installation, on the one hand, by rotating the axial clearance adjusting component 4, it moves along the supporting screw 2. This allows the axial clearance adjusting component 4 to move axially along the part of the cylinder section that is welded to it, thus adjusting the axial clearance of that part of the cylinder section. On the other hand, by using a wrench to hold one end of the adjusting screw 8 in place, and then using another wrench to rotate the radial clearance adjusting component 7, it moves along the adjusting screw 8. This allows the axial clearance adjusting component 4 to move radially along the part of the cylinder section that is welded to it, thus adjusting the radial clearance of that part of the cylinder section. It is important to emphasize that measurements must be taken during the adjustment process. By adjusting the clamps on the circumference of the cylinder section one by one, the bevel assembly size can be fully adjusted. After the adjustment is completed, the cylinder section is welded. After welding, the support screw 2 and the adjusting screw 8 can be removed by rotating and disassembling. Only the axial clearance adjustment component 4, support component 5, positioning sleeve 6 and radial clearance adjustment component 7 remain on the cylinder section. The welding between these components and the cylinder section is approximately spot welding. They can be quickly disassembled by knocking them off. The welding surface left after disassembly is small, which is convenient for quick grinding and repair.

[0017] Preferably, the bracket includes two side rods 1, and the center of the side rod 1 is provided with a protrusion 3 for fixing the two ends of the support screw 2. Two radial clearance adjustment parts 7 are provided on the same side rod 1. The setting of the protrusion 3 can make the support screw 2 relatively closer to the cylinder, and the four corners of the bracket relatively farther away from the cylinder. This allows the distribution of the axial clearance adjustment part 4, the support part 5, the radial clearance adjustment part 7 and the positioning sleeve 6 to adapt to the curvature of the cylinder, so that the axial clearance adjustment part 4 and the support part 5 are close enough to the cylinder. At the same time, the length of the adjusting screw 8 is sufficient to provide enough adjustment space for the radial clearance adjustment part 7.

[0018] Preferably, the axial clearance adjusting member 4 includes a first adjusting screw sleeve 401, a connecting sleeve 402 rotatably sleeved on the first adjusting screw sleeve 401, and a fixed post 403 provided on the connecting sleeve 402. Rotating the first adjusting screw sleeve 401 can move the axial clearance adjusting member 4 along the support screw 2.

[0019] Preferably, the radial clearance adjusting member 7 includes a second adjusting screw sleeve 701 and a fixed sleeve 702 rotatably sleeved on the second adjusting screw sleeve 701. Rotating the second adjusting screw sleeve 701 can move the radial clearance adjusting member 7 along the adjusting screw 8.

[0020] Preferably, the end of the fixed sleeve 702 away from the bracket protrudes from the end face of the second adjusting screw sleeve 701. This protruding end face is the welding surface with the cylinder section. This welding surface is offset from the end face of the second adjusting screw sleeve 701, which can avoid the situation where the second adjusting screw sleeve 701 is welded and fixed due to excessive use of welding material.

[0021] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
