Description

Technical Field

[0001] This utility model belongs to the field of jack manufacturing technology, specifically relating to a welding structure for a thin-walled jack joint. Background Technology

[0002] The common method for connecting the fluid pipe of a mining hydraulic jack is to weld the connector directly to the cylinder body. The fluid passage hole of the connector in the vertical direction to the cylinder body is usually drilled through, and then welded to the cylinder body. The machine is then transported to a drilling machine to drill through the cylinder body along the connector hole, and finally transferred to the welding workshop to weld the upper end of the connector hole.

[0003] During the welding process of jack joints, it is often difficult to position and limit the quick connector. This is mainly due to insufficient preparation before welding, non-standard operation during welding, and insufficient precision of welding equipment. If the quick connector is misaligned during welding, it will not only lead to welding failure, but also waste a lot of time and materials, increase production costs, and after multiple welding failures, the heat accumulation in the welding area will cause the temperature of the thin-walled part to become too high, thus melting and deforming. This will not only further increase the difficulty of welding, but may also lead to the scrapping of the entire jack joint, affecting the production progress and product quality.

The pressing bolt 7 is threadedly connected to the groove on the outer wall of the positioning rod 5.

[0027] In a specific embodiment of this utility model, the welding assembly, utilizing the matching of the conical head 6 and the connecting groove 102, as well as the cooperation of the positioning rod 5 and the limiting groove 201, allows the quick connector 2 to be conveniently and quickly installed in the designated position. The pressing bolt 7 generates a pressing force on the quick connector 2, preventing misalignment and ensuring the stability of the welding. A weld 101 is welded at the gap between the cylinder body 1 and the quick connector 2, further ensuring the firmness of the connection. The movable protective sleeve 4 can protect the outer wall of the quick connector 2, preventing the pipeline from being punctured or scratched, and improving the sealing performance of the quick connector 2. The matching of the positioning rod 5 and the limiting groove 201, as well as the recessed setting at one end of the positioning rod 5, can improve the positioning efficiency.

[0028] Specifically, a sliding groove 501 is provided on the top of the outer wall of the positioning rod 5, and the sliding groove 501 matches the protruding end of the inner wall of the protective sleeve 4.

[0029] In a specific embodiment of this utility model, the sliding groove 501 matches the protruding end of the inner wall of the protective sleeve 4, which can ensure the movement accuracy.

[0030] Specifically, a weld 101 is welded at the gap between the cylinder body 1 and the quick connector 2.

[0031] In a specific embodiment of this utility model, a weld 101 is welded at the gap between the cylinder body 1 and the quick connector 2 to ensure stable fixation.

[0032] Specifically, the bottom end of the extrusion bolt 7 is attached to the bottom of the inner wall of the limiting groove 201.

[0033] In a specific embodiment of this utility model, the bottom end of the extrusion bolt 7 is attached to the bottom of the inner wall of the limiting groove 201, which can ensure stable extrusion.

[0034] Specifically, the quick connector 2 and the outer wall of the protective sleeve 4 are provided with fixing holes 401.

[0035] In a specific embodiment of this utility model, the quick connector 2 and the outer wall of the protective sleeve 4 are provided with fixing holes 401, which can be easily fixed by bolts.

[0036] Specifically, one end of the positioning rod 5 is recessed.

[0037] In a specific embodiment of this utility model, one end of the positioning rod 5 is recessed to ensure positioning efficiency.

[0038] Working Principle: Ensure that components such as cylinder body 1, quick connector 2, base 3, protective sleeve 4, positioning rod 5, conical head 6, extrusion bolt 7, and sealing ring 8 are intact and free from defects such as deformation or cracks. Clean all components, especially welded areas, with an appropriate cleaning agent to ensure that there is no oil or impurities that could affect the welding quality. Prepare welding equipment, wrenches, bolts, and other installation tools. Embed base 3 into the inner wall of one end of cylinder body 1, ensuring it is firmly fixed without any looseness. Fix positioning rod 5 to the outer wall of base 3, noting that one end of positioning rod 5 is recessed for subsequent positioning. In the positioning operation, the conical head 6 is fixed at the bottom of the outer wall of the quick connector 2. Then, the quick connector 2 is aligned with the connecting groove 102 at the top of the outer wall of the cylinder body 1. By matching the conical head 6 with the connecting groove 102, the quick connector 2 is initially installed in the designated position. A sealing ring 8 is fitted onto the outer wall of the conical head 6, ensuring that the sealing ring 8 is installed in place without twisting or damage. The limiting groove 201 of the quick connector 2 is aligned and engaged with the positioning rod 5. By matching the positioning rod 5 with the limiting groove 201, the positioning efficiency and accuracy are improved. Finally, the extrusion bolt 7 is threaded into place. The quick connector 2 is attached to the slotted outer wall of the positioning rod 5, and the clamping bolt 7 is tightened so that its bottom end fits against the bottom of the inner wall of the limiting groove 201, generating a stable clamping force on the quick connector 2 to prevent misalignment and ensure welding stability. Welding is then performed at the gap between the cylinder body 1 and the quick connector 2 to form weld 101, further ensuring the connection's firmness and sealing. During welding, welding parameters are carefully controlled to avoid overheating that could affect component performance. After welding is completed, the protective sleeve 4 is moved to cover the outer wall of the quick connector 2 to protect it from punctures and scratches to the pipeline. To improve the sealing performance and service life of the quick connector 2, the protruding end of the inner wall of the protective sleeve 4 matches the sliding groove 501 on the top of the outer wall of the positioning rod 5 to ensure movement accuracy. Using the fixing holes 401 opened on the outer wall of the quick connector 2 and the protective sleeve 4, the protective sleeve 4 is further fixed by bolts and other fasteners to ensure that it will not loosen or shift during use. The entire welding assembly is inspected to ensure that each component is firmly installed and there are no loose or missing welds. If necessary, pressure tests are performed to verify its sealing performance and reliability, ensuring that the thin-walled jack joint welding structure can work normally.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
