Description

Technical Field

[0001] This utility model belongs to the field of copper tube production and processing technology, and in particular relates to a copper tube production and processing water pressure testing machine. Background Technology

[0002] In the copper tube manufacturing and processing industry, hydrostatic testing is a crucial step in evaluating the quality and performance of copper tubes, directly impacting their safety and reliability in practical applications. However, existing hydrostatic testing machines for copper tube manufacturing and processing on the market have numerous problems and fail to meet the industry's growing demands.

[0003] Traditional hydrostatic testing machines often use simple clamp designs when holding copper pipes, which cannot achieve precise positioning and stable fixation. These clamps may not guarantee the coaxiality of the copper pipe during the test, leading to uneven stress on the pipe and making it prone to local deformation or even breakage during the test, thus affecting the accuracy of the test results. Moreover, this simple clamping method may not effectively prevent water leakage, causing deviations in the test data and failing to truly reflect the sealing performance of the copper pipe. Utility Model Content

[0004] To achieve the above objectives, this utility model proposes a copper tube production and processing hydraulic testing machine, which includes a testing machine body. A clamping mechanism is fixedly installed on the side wall of the testing machine body. The clamping mechanism includes a threaded tube, which is fixedly installed on the side wall of the testing machine body. A first threaded sleeve is threadedly installed on the side wall of the threaded tube. A first rubber gasket is fixedly installed inside the first threaded sleeve. An installation rod is fixedly installed at the end of the threaded tube away from the testing machine body. A threaded rod is fixedly installed at the end of the installation rod away from the threaded tube. A second threaded sleeve is threadedly installed on the side wall of the threaded rod. A second rubber gasket is fixedly installed inside the second threaded sleeve.

[0005] In one example, a mounting base is fixedly installed on the side wall of the threaded pipe, and a fixing plate is fixedly installed on the top of the mounting base.

[0006] In one example, a rotating rod is rotatably mounted inside the fixed plate.

[0007] In one example, a clamping block is fixedly mounted on the side wall of the rotating rod, and a torsion spring is sleeved on the side wall of the clamping block.

[0008] In one example, the torsion spring is fixedly mounted to the fixing plate.

[0009] In one example, the end of the torsion spring away from the fixed plate is fixedly mounted to the clamping block.

[0010] In one example, the rotating rod sidewall is equipped with a synchronous belt drive assembly.

[0011] In one example, a plug-in plate is slidably mounted on top of the mounting base.

[0012] The copper tube production and processing hydraulic testing machine proposed in this utility model can bring the following beneficial effects:

[0013] 1. This utility model achieves precise and efficient clamping and fixing of copper tubes. Utilizing threaded tubes, threaded rods, corresponding threaded sleeves, and rubber gaskets, the copper tubes are securely clamped from both ends. The rubber gaskets not only increase friction but also effectively prevent water leakage during the hydrostatic test, ensuring the accuracy and stability of the test. At the same time, the synchronous movement of the clamping blocks is controlled by a torsion spring, rotating rod, and synchronous belt drive assembly, which can evenly clamp the copper tubes at various positions, ensuring uniform force on the copper tubes during the test, avoiding test errors caused by uneven clamping, and improving test efficiency and the reliability of the results.

[0014] 2. This practical testing machine possesses excellent versatility. The sliding plug-in plate on the mounting base, fitted onto the side wall of the threaded rod, allows for flexible adjustment of the clamping structure, adapting to copper pipes of different sizes. Whether small or large diameter, copper pipes can be stably clamped using this structure, eliminating the need for multiple specialized clamps for different specifications. This reduces equipment costs, enhances the equipment's adaptability to diverse production needs, meets the requirements for hydrostatic testing of copper pipes of different specifications during copper pipe production and processing, and improves the equipment's usability and application range.

[0021] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0022] Example:

[0023] like Figures 1-4 As shown in the figure, an embodiment of this utility model proposes a hydrostatic testing machine for copper pipe production and processing, which includes a testing machine body 11. In use, the testing machine body 11 serves as the main body of the entire equipment, providing an installation foundation and working platform for other components. A threaded pipe 12 is fixedly installed on the side wall of the testing machine body 11. The threaded pipe 12 is used to connect and fix other components, and at the same time provides a threaded installation position for a first threaded sleeve 13. The first threaded sleeve 13 is threadedly installed on the side wall of the threaded pipe 12. In use, rotating the first threaded sleeve 13 on the threaded pipe 12 counterclockwise will cause the first threaded sleeve 13 to move along the threaded structure of the threaded pipe 12. A first rubber gasket 14 is fixedly installed inside the first threaded sleeve 13. When the first threaded sleeve 13 moves, it will drive the first... The rubber gasket 14 gradually approaches the copper tube. The first rubber gasket 14 increases the contact friction and sealing with the copper tube, thereby better fixing the copper tube and preventing water leakage during the water pressure test. The end of the threaded tube 12 away from the test machine body 11 is fixedly installed with an installation rod 15. The installation rod 15 is used to support and position the copper tube. During operation, the copper tube is placed on top of the installation rod 15 so that the installation rod 15 is located in the center of the copper tube, providing a reference for clamping and test operation. The end of the installation rod 15 away from the threaded tube 12 is fixedly installed with a threaded rod 18. The threaded rod 18 also provides a threaded installation position for the second threaded sleeve 17, which cooperates with the threaded tube 12 and the first threaded sleeve 13 to complete the clamping of the copper tube.

[0024] A second threaded sleeve 17 is threadedly installed on the side wall of the threaded rod 18. Rotating the second threaded sleeve 17 counterclockwise causes it to move along the threaded structure of the threaded rod 18. A second rubber gasket 16 is fixedly installed inside the second threaded sleeve 17. The movement of the second threaded sleeve 17 causes the second rubber gasket 16 to gradually approach the copper tube, clamping the copper tube from both ends together with the first rubber gasket 14, further increasing the stability of the copper tube during the test and enhancing the sealing performance. A mounting base 19 is fixedly installed on the side wall of the threaded tube 12. The mounting base 19 provides mounting positions for components such as the fixed plate 25, the rotating rod 21, and the synchronous belt drive assembly 24, and is an important support structure for realizing the copper tube clamping action. A fixed... The fixed plate 25 is used to install the rotating rod 21 and provide a fixing point for the torsion spring 23, ensuring the normal operation of the torsion spring 23 and the rotating rod 21. The rotating rod 21 is rotatably installed inside the fixed plate 25. When in use, the clamping block 22 is flipped counterclockwise, and the clamping block 22 drives the rotating rod 21 to rotate counterclockwise. When the clamping block 22 is released, the torsion spring 23 releases its torsion and drives the rotating rod 21 to rotate clockwise. The rotating rod 21 plays the role of transmitting power and controlling the movement of the clamping block 22. The clamping block 22 is fixedly installed on the side wall of the rotating rod 21. When in use, the clamping block 22 is first flipped counterclockwise, and then the copper tube is placed on the mounting rod 15 and released. Under the action of the torsion spring 23, the clamping block 22 rotates clockwise to clamp the copper tube, and the copper tube is directly clamped.

[0025] A torsion spring 23 is sleeved on the side wall of the clamping block 22. The torsion spring 23 is fixedly installed on the fixing plate 25. The end of the torsion spring 23 away from the fixing plate 25 is fixedly installed on the clamping block 22. When the clamping block 22 is rotated counterclockwise, the torsion spring 23 is twisted. When the clamping block 22 is released, the torsion spring 23 releases its torsion, driving the rotating rod 21 and the clamping block 22 to reset, thus clamping the copper tube and providing reset power for the clamping block 22. A synchronous belt drive assembly 24 is installed on the side wall of the rotating rod 21. When the rotating rod 21 rotates counterclockwise, it drives the torsion spring. 23 generates torsion, and at the same time, the torsion spring 23 drives the rotating rod 21 to rotate counterclockwise, so that all the clamping blocks 22 and the synchronous belt drive assembly 24 connected to the rotating rod 21 can move synchronously, ensuring the consistency of clamping the copper tube at various positions. The top of the mounting base 19 is slidably mounted with a plug plate 26. By sliding the plug plate 26, the plug plate 26 is fitted onto the side wall of the threaded rod 18, which increases the stability of the entire clamping structure. In this way, copper tubes of different sizes can be clamped, enhancing the adaptability of the equipment to copper tubes of different specifications.

[0026] Working principle: The testing machine body 11 serves as the core. A threaded tube 12 fixed to its side wall connects and secures other components, providing an installation position for the first threaded sleeve 13. An installation rod 15 at one end of the threaded tube 12 supports and positions the copper tube. A threaded rod 18 connected to the other end of the installation rod 15 cooperates with the threaded tube 12 to provide an installation position for the second threaded sleeve 17, together forming a clamping frame for the copper tube. Simultaneously, the mounting seat 19 on the side wall of the threaded tube 12 provides mounting support for related components that realize the copper tube clamping action, such as the fixed plate 25, the rotating rod 21, and the synchronous belt drive assembly 24. The rotating rod 21, rotatably mounted inside the fixed plate 25, has a clamping block 22 fixed to its side wall for clamping. A torsion spring 23 is sleeved on the side wall of block 22. The two ends of the torsion spring 23 are fixed to the fixing plate 25 and the clamping block 22 respectively. During operation, the clamping block 22 is first rotated counterclockwise, which drives the rotating rod 21 to rotate counterclockwise, causing the torsion spring 23 to twist. At the same time, the rotating rod 21 drives other connected rotating rods 21 and clamping blocks 22 to rotate counterclockwise synchronously through the synchronous belt drive assembly 24. After the copper tube is sleeved above the mounting rod 15, the clamping block 22 is released. The torsion spring 23 releases its torsion, which drives the rotating rod 21 to rotate clockwise, which in turn drives the clamping block 22 to rotate clockwise, thus achieving the clamping of the copper tube. The synchronous belt drive assembly 24 ensures the consistency of the movement of all clamping blocks 22, ensuring that the copper tube is clamped evenly at all positions.

[0027] Rotating the first threaded sleeve 13 on the threaded tube 12 counterclockwise causes it to move along the threaded structure, bringing the first rubber gasket 14 inside closer to the copper tube. This increases the friction and sealing between the rubber gasket and the copper tube, fixing the copper tube from one end and preventing leakage. Rotating the second threaded sleeve 17 on the threaded rod 18 counterclockwise causes it to move along the thread of the rod 18, bringing the second rubber gasket 16 inside closer to the copper tube. This gasket 16 cooperates with the first rubber gasket 14 to clamp the copper tube from both ends, further stabilizing the copper tube and enhancing the sealing, preparing for the hydrostatic test. The sliding plug plate 26 on the top of the mounting base 19 can be fitted onto the side wall of the threaded rod 18, increasing the stability of the entire clamping structure. In this way, the equipment can adapt to copper tubes of different sizes, enhancing its clamping capacity for copper tubes of various specifications and meeting diverse testing needs.
