Description

Technical Field

[0001] This utility model relates to the field of hydrogen storage bottle production and testing technology, specifically to a hydrogen storage bottle tube blank performance testing device. Background Technology

[0002] With the increasing demand for clean energy, hydrogen energy, as a highly promising energy carrier, is finding increasingly widespread applications. As a key component for storing hydrogen, the quality and performance of hydrogen storage cylinders directly affect the safety and reliability of hydrogen energy systems. Before being processed into finished hydrogen storage cylinders, hydrogen storage cylinder preforms undergo rigorous testing for multiple properties, such as strength, sealing performance, and fatigue resistance.

[0003] Traditional methods for inspecting hydrogen storage cylinder tube blanks often rely on rudimentary fixtures. When fixing the tube blank, it's difficult to ensure its stability during inspection, leading to displacement or shaking. This not only affects the accuracy of the test data, causing misjudgments of the tube blank's performance, but can also damage the testing equipment and the tube blank sample. Furthermore, some existing testing devices lack versatility; it's difficult to quickly and easily adjust the fixtures to adapt to different specifications and sizes of hydrogen storage cylinder tube blanks, significantly reducing testing efficiency and failing to meet the growing production demands of hydrogen storage cylinders. In addition, if the forces between the tube blank and the fixture are not effectively buffered during inspection, clamp marks and other damage may be left on the tube blank surface, further affecting its quality. Utility Model Content

[0004] This utility model addresses the aforementioned problems in the existing technology by providing a hydrogen storage cylinder tube blank performance testing device. This device enables stable clamping of the tube blank, rapid clamping to adapt to different specifications, and effectively protects the tube blank surface, ensuring the accuracy and efficiency of the testing.

[0005] The objective of this utility model is mainly achieved through the following solution:

[0006] A hydrogen storage cylinder tube blank performance testing device includes a base platform. A bracket is rotatably connected to the top surface of the base platform. A first clamp is fixed to one end of the top surface of the bracket. A threaded roller is rotatably connected inside the bracket. The end of the threaded roller away from the first clamp passes through the bracket and is connected to a turntable. A handle is fixed on the turntable. A calibration screw is threadedly connected to the turntable. The side wall of the bracket has several threaded slots that mate with the calibration screw. The end of the calibration screw away from the threaded slots is connected to... The threaded roller is connected to a screw ring via a screw thread. A moving block is connected to the top surface of the screw ring. The moving block passes through the long slot hole on the top surface of the bracket and is connected to the bottom surface of the secondary clamping piece. Several anti-movement blocks are provided on the side walls of the primary clamping piece and the secondary clamping piece that are close to each other. Each anti-movement block includes a cylindrical tube. A limiting column is slidably connected inside the cylindrical tube. One end of the limiting column located inside the cylindrical tube is fixedly connected to the cylindrical tube by a shock-absorbing spring. The other end of the limiting column is connected to a rubber column.

[0007] Preferably, the top surface of the base is provided with a support column, and the bottom surface of the base is provided with a notch. The top of the support column is rotatably connected to the notch via a head shaft seat. The side wall of the support column is provided with a fixed plate, and the bottom surface of the fixed plate is connected to a solid cavity. A sliding piece is slidably connected in the solid cavity. The bottom surface of the sliding piece is connected to a pull strip, and a restoring spring is sleeved on the pull strip. The restoring spring is located inside the solid cavity. The pull strip passes through the bottom surface of the solid cavity and is connected to the pull piece. The top surface of the sliding piece is connected to a retaining strip, and the retaining strip passes through the top surface of the solid cavity and the fixed plate. The bottom surface of the base is provided with multiple retaining slots that cooperate with the retaining strip.

[0008] Preferably, the bracket has two sliding rods inside, which are symmetrically arranged about the threaded rod as the axis of symmetry.

[0009] Preferably, the end of the adhesive column away from the limiting post is arc-shaped.

[0010] Preferably, the base is provided with anti-slip pads at the four corners of its bottom surface.

[0011] Preferably, the threaded roller is rotatably connected inside the bracket via a secondary shaft seat.

[0012] Therefore, compared with the prior art, the present invention has the following advantages:

[0013] (1) This utility model can stably clamp the hydrogen storage bottle tube blank from multiple directions by setting the first clamping piece, the second clamping piece and the anti-displacement block. The damping spring and the rubber column in the anti-displacement block can not only buffer the clamping force and avoid damage to the tube blank, but also effectively prevent the tube blank from small displacement during the testing process, ensuring the accuracy of the test data. Compared with the traditional simple clamp, it greatly improves the clamping stability.

[0014] (2) With the setting of threaded roller, turntable, handle and calibrating screw, the operator can easily adjust the position of the secondary clamping plate by simply turning the handle, so as to realize the quick clamping of tube blanks of different diameters. The calibrating screw can accurately position the turntable, adapt to frequent clamping operations, improve work efficiency, and can be widely used for the detection of hydrogen storage bottle tube blanks of various specifications, effectively solving the problem of poor versatility of traditional devices.

[0015] (3) The bottom platform and the support column of this utility model adopt a rotatable connection structure, with the help of the locking strip and the pull plate, so that the device can quickly adjust the tilt angle of the bottom platform according to the actual testing needs, meet the requirements of performance testing of hydrogen storage cylinder tube blank under different working conditions, and further expand the application scope of the device.

[0016] (4) In this utility model, the sliding rod and sliding ring in the bracket provide a smooth guide for the movement of the secondary clamping piece, ensuring that the secondary clamping piece always maintains a straight line movement when it approaches the first clamping piece to clamp the tube blank, avoiding deviation, improving the clamping accuracy, and helping to improve the detection accuracy.

Detailed Implementation

[0024] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.

[0025] In this invention, unless otherwise specified, all parts and percentages are by weight, and the equipment and raw materials used are commercially available or commonly used in the field. Unless otherwise specified, the methods in the following embodiments are conventional methods in the field. Unless otherwise specified, the components or equipment in the following embodiments are general standard parts or components known to those skilled in the art, and their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0026] Example 1:

[0027] like Figure 1As shown, this utility model provides a technical solution: a hydrogen storage cylinder tube blank performance testing device, including a base 1. Anti-slip pads 34 are provided at the four corners of the base 1's bottom surface. A bracket 2 is rotatably connected to the top surface of the base 1. A first clamping piece 3 is fixed to one end of the top surface of the bracket 2. A threaded roller 4 is rotatably connected inside the bracket 2. The threaded roller 4 is rotatably connected inside the bracket 2 via a secondary shaft seat 35. The end of the threaded roller 4 away from the first clamping piece 3 passes through the bracket 2 and is connected to a turntable 5. A handle 6 is fixed on the turntable 5. A calibration screw 7 is threadedly connected to the turntable 5. Several threaded slots 8 are opened on the side wall of the bracket 2 to mate with the calibration screw 7. A torsion handle 9 is connected to the end away from the screw groove hole 8. A screw sleeve 10 is threadedly connected to the threaded rod 4. A moving block 11 is connected to the top surface of the screw sleeve 10. The moving block 11 passes through the long slot hole 12 on the top surface of the bracket 2 and is connected to the bottom surface of the secondary clamping piece 13. Several anti-movement blocks 14 are provided on the side walls of the primary clamping piece 3 and the secondary clamping piece 13 that are close to each other. The anti-movement block 14 includes a cylindrical tube 15. A limiting column 16 is slidably connected inside the cylindrical tube 15. One end of the limiting column 16 located inside the cylindrical tube 15 is fixedly connected to the cylindrical tube 15 by a damping spring 17. The other end of the limiting column 16 is connected to a rubber column 18. The end of the rubber column 18 away from the limiting column 14 is arc-shaped.

[0028] In use, the hydrogen storage cylinder blank to be tested is placed between the first clamp 3 and the second clamp 13. Rotating the handle 6 drives the turntable 5 to rotate, which in turn drives the threaded roller 4 to rotate. The rotation of the threaded roller 4 causes the threaded sleeve 10 to move along the threaded roller 4, thereby driving the moving block 11 and the second clamp 13 to move closer to the first clamp 3 until the blank is clamped. Then, rotating the torsion handle 9 drives the alignment screw 7 to rotate, so that the end of the alignment screw 7 is engaged in the threaded groove hole 8, thereby fixing the position of the second clamp 13. At this time, the rubber column 18 in the anti-displacement block 14 is in close contact with the surface of the blank, preventing the blank from shifting during the testing process.

[0029] Example 2:

[0030] Based on Embodiment 1, a support column 19 is provided on the top surface of the base platform 1, and a recess 20 is provided on the bottom surface of the base platform 1. The top of the support column 19 is rotatably connected to the recess 20 through a head shaft seat 21. A fixed plate 22 is provided on the side wall of the support column 19, and a solid cavity 23 is connected to the bottom surface of the fixed plate 22. A sliding piece 24 is slidably connected in the solid cavity 23, and a pull strip 25 is connected to the bottom surface of the sliding piece 24. A restoring spring 26 is sleeved on the pull strip 25 and is located inside the solid cavity 23. The pull strip 25 penetrates the bottom surface of the solid cavity 23 and is connected to the pull piece 27. A retaining strip 28 is connected to the top surface of the sliding piece 24 and penetrates the top surface of the solid cavity 23 and the fixed plate 22. Multiple retaining slots 29 that cooperate with the retaining strip 28 are provided on the bottom surface of the base platform 1.

[0031] When the height of the base platform 1 needs to be adjusted, pull tab 27 is pulled to drive pull strip 25 and slide tab 24 to slide in the solid cavity 23, while compressing the restoring spring 26. At this time, the locking strip 28 disengages from the locking slot 29, allowing the support column 19 to rotate in the recess 20, thereby adjusting the height of the base platform 1. After the adjustment is completed, pull tab 27 is released, and the elasticity of the restoring spring 26 causes the slide tab 24 and locking strip 28 to return to their original positions. The locking strip 28 then engages in the corresponding locking slot 29, thus fixing the height of the base platform 1.

[0032] Example 3:

[0033] Based on embodiment 1, the bracket 2 is provided with two sliding rods 30 inside. The two sliding rods 30 are symmetrically arranged with the threaded rod 4 as the axis of symmetry. A sliding ring 31 is slidably connected to the sliding rod 30. A sliding block 32 is connected to the top surface of the sliding ring 31. The sliding block 32 passes through the groove 33 on the top surface of the bracket 2 and is connected to the bottom surface of the secondary clamping piece 13.

[0034] The introduction of the slide bar 30 and the slide ring 31 structure provides additional support and guidance for the secondary clamping piece 13. During the movement of the secondary clamping piece 13, the slide ring 31 slides along the slide bar 30 to ensure that the movement of the secondary clamping piece 13 is more stable and accurate.

[0035] The hydrogen storage cylinder tube blank performance testing device provided in this application has the advantages of simple operation, high testing accuracy, and good stability. It can accurately test the performance of hydrogen storage cylinder tube blanks and meet the needs of the modern hydrogen energy industry for high-quality hydrogen storage cylinder tube blanks.
