[0014] An operating method of a liquid storage cylinder assembly pull-off strength test tool, characterized in that it comprises the following steps:

[0015] S1. Preparation: When preparing to start the pull-off strength test of the liquid storage cylinder assembly, first check the tooling body and various components to ensure the integrity and accuracy of all components, including the left half mold, the right half mold, the support column, the upper connecting device, the connecting support device and the locking device, to avoid the test results being affected by manufacturing defects;

[0016] S2. Installation of the tooling body: After all parts are prepared, start to install the tooling body. First, place the support column on the right half mold, then merge the left half mold and the right half mold together, so that the support column is located in the mounting hole in the cylindrical mold. Finally, use the locking nut to fix the left half mold, the right half mold and the support column through the locking hole, and then check whether the support column is stable, and ensure that the thread in the through hole of the support column is tightly fitted with the outer surface of the support column to avoid affecting the stability of the test due to looseness;

[0017] S3. Installation of the upper connection device: After the tooling body is installed, the connection hole on the upper part of the support column is coaxially connected with the fixing hole on the test equipment, and then the limiting column is passed through the connection hole on the upper part of the support part and the fixing hole on the test equipment to fix the connection, ensuring that it does not fall off or loosen during the entire pull-off strength test process;

[0018] S4. Installation of the connecting support device: After the upper connecting device is installed, the connecting hole at the bottom of the support column is coaxially connected with the fixing hole on the support base, and then the supporting pin is inserted into the connecting hole at the bottom of the support column and fixedly connected with the fixing block on the support base. In addition, the angle of the support base needs to be adjusted according to the test requirements to ensure that the supporting device stably supports the tooling body during the test;

[0019] S5. Check the stability of the tooling: After all parts are installed, it is necessary to check the stability of the locking device, the upper connecting device and the connecting support device again to confirm that the tooling body will not be displaced or fall off during the entire test process;

[0020] S6. Installation of the liquid cylinder assembly: After the tooling body has been installed and confirmed to be stable, start installing the liquid storage cylinder assembly; align the liquid storage cylinder assembly with the fixed position on the tooling body, and then carefully install the liquid storage cylinder assembly at the designated position on the tooling body, and check whether the liquid storage cylinder assembly is completely fixed and ensure that it does not move;

[0021] S7. Debugging of test equipment: After the inspection is completed, debug the test equipment; check whether the pull-off strength test equipment is correctly connected and confirm that the equipment can operate normally. During the debugging process, special attention should be paid to the sensitivity of the equipment's tension sensor and measuring instrument to ensure that they can accurately read the pull-off strength value;

[0022] S8. Start the pull-off strength test: After the test equipment is debugged, the pull-off strength test is officially started. The test equipment is started, and the pulling force is slowly increased until the pull-off force of the liquid storage cylinder assembly reaches the set value. During the test, the data changes on the test equipment are monitored in real time to ensure that the test process is carried out smoothly and the pull-off strength data is accurate.

[0023] S9. Record test data: After the test is completed, record the value of the pull-off strength and the factors that affect the test results, including but not limited to the installation of the tooling and the performance of the test equipment;

[0024] S10, test result analysis: after all test data are recorded, compare the test data with the standard value to evaluate whether the pull-off strength of the liquid storage cylinder assembly meets the requirements. If the test results do not meet the requirements, it is necessary to analyze the reasons based on the test data, and may re-test or adjust the tooling design;

[0025] S11, cleaning and disassembly: After the test results are analyzed, start cleaning and disassembling the tooling, disassemble the tooling parts in sequence, and perform cleaning and maintenance to ensure the long-term service life of the equipment and tooling;

[0026] S12. Record and archive: When all disassembly and cleaning work is completed, organize the test report and archive it for future reference. The test report includes but is not limited to the use of the tooling, the performance of the liquid storage cylinder assembly, and the pull-off strength value.

[0027] The present invention is further configured as follows: the adjustable angle range of the support base is 5°-20°, and the sensitivity of the adjustment angle is 1°. This design can be finely adjusted according to different test requirements to improve the applicability and test accuracy of the tooling.

[0028] The beneficial effects of the present invention are:

[0029] 1. Compared with the prior art, the pull-off strength test tooling of the liquid storage cylinder assembly of the present invention can effectively support and fix the liquid storage cylinder assembly through carefully designed components to ensure that its shape does not change, and avoid deformation and deviation during the pull-off strength test. The coordinated use of the upper connecting device, the connecting support device and the locking device ensures the stability of the tooling, so that the tooling will not loosen or shift when the tension is applied, thereby ensuring the test accuracy. This design not only improves the reliability of the test process, but also improves the accuracy of the experimental results, ensures the credibility of the pull-off strength data, and can meet high-standard test requirements.

[0030] 2. The pull-off strength test fixture of the liquid storage cylinder assembly of the present invention has strong structural stability through the combination of the left half mold, the right half mold and the support column. The thread design between the cylindrical mold and the through hole of the support column increases the friction force, avoids the loosening phenomenon that may occur during the pull-off strength test, and ensures the stable connection of the test equipment.

[0031] 3. In the present invention, by limiting the close connection between the column and the supporting column and the fixing holes on the test equipment, the stability between the test equipment and the test equipment during the test process is ensured. This design can effectively prevent the upper connection from falling off or loosening due to increased tension, thereby ensuring the safety of the test process and the accuracy of the data. The plug-in fixation simplifies the operation steps and makes the overall device have higher tensile strength, effectively ensuring the linkage between the equipment, so that the tooling can withstand higher tension during the test without being affected by external interference, thereby improving the reliability of the test equipment and the durability of the tooling.

[0036] Reference Figure 1-2The embodiment of the pull-off strength test tool for the liquid storage cylinder assembly and the operation method thereof of the present invention is further described.

[0037] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to illustrate the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "on" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0038] Furthermore, relational terms such as “first” and “second” and the like are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any such actual relationship or order between these components.

[0039] Figure 1 to Figure 2 The pull-off strength test tool for a liquid storage cylinder assembly shown in the figure includes:

[0040] Tool body 1: used to support the liquid storage cylinder assembly and ensure that its shape does not change;

[0041] Upper connecting device 2: used to connect the liquid storage cylinder assembly to the test equipment;

[0042] Connecting support device 3: used to support the lower part of the liquid storage cylinder assembly and keep it stable;

[0043] Locking device 4: used to ensure stable connection and fixation of various components and ensure the accuracy of pull-off strength measurement during the test;

[0044] Through the careful design of various components, the liquid storage cylinder assembly can be effectively supported and fixed to ensure that its shape does not change, and deformation and deviation are avoided during the pull-off strength test. The coordinated use of the upper connecting device 2, the connecting support device 3 and the locking device 4 ensures the stability of the tooling, so that the tooling will not loosen or shift when the tension is applied, thereby ensuring the test accuracy. This design not only improves the reliability of the test process, but also improves the accuracy of the experimental results, ensures the credibility of the pull-off strength data, and can meet high-standard test requirements.

[0045] The tooling body 1 comprises: a left half mold 5, a right half mold 6 and a support column 7. The left half mold 5 and the right half mold 6 are combined to form a cylindrical mold. A through hole for installing the support column 7 is coaxially penetrated in the center of the cylindrical mold, and a thread is provided on the inner wall of the through hole for increasing friction. The cylindrical mold is symmetrically provided with locking holes that penetrate the cylindrical mold and are close to the connection between the left half mold 5 and the right half mold 6 for fixing the cylindrical mold; the top and bottom of the support column 7 are respectively provided with connection holes for connection;

[0046] The height of the left half mold 5 is smaller than that of the right half mold 6, and the height of the support column 7 is greater than that of the cylindrical mold. After installation, the connection holes on the tooling body 1 are completely exposed to the outside;

[0047] The combination of the left half mold 5, the right half mold 6 and the support column 7 has a strong structural stability. The threaded design between the cylindrical mold and the through hole of the support column 7 increases the friction force, avoids the loosening phenomenon that may occur during the pull-off strength test, and ensures the stable connection of the test equipment.

[0048] The upper connection device 2 includes a limiting column, which is fixedly connected to each other by being inserted into a connection hole on the upper part of the support column 7 and a fixing hole on the test equipment to ensure that it does not fall off during the test;

[0049] By limiting the tight connection between the column and the support column 7 and the fixing holes on the test equipment, the stability between the test equipment and the test equipment is ensured during the test. This design can effectively prevent the upper connection from falling off or loosening due to increased tension, ensuring the safety of the test process and data accuracy. The plug-in fixation simplifies the operation steps and makes the overall device have higher tensile strength, effectively ensuring the linkage between the equipment, so that the tooling can withstand higher tension during the test without being affected by external interference, thereby improving the reliability of the test equipment and the durability of the tooling.

[0050] The connecting support device 3 includes a supporting base 8 and a supporting pin 9 that can be installed on the supporting base 8. The supporting pin 9 is fixedly connected to each other by being inserted into a connecting hole at the bottom of the supporting column 7 and a fixing hole on the supporting base 8. The angle of the supporting base 8 is adjustable to ensure stable support during the test.

[0051] The structure of the adjustable support base 8 and the support pin 9 ensures that the lower part of the tooling can stably support the entire liquid storage cylinder assembly, and the angle of the support base 8 can be adjusted according to the test requirements, so that the tooling can adapt to different test scenarios. Through this angle adjustment function, the tooling can be supported more accurately under different test conditions, thereby improving the applicability of the tooling and the accuracy of the test. The adjustable angle design of the support base 8 solves the problem of the inapplicability of fixed angles under different test environments, making the tooling more versatile and adaptable to a variety of test requirements, greatly improving its operational flexibility and functionality.

[0052] The locking device 4 includes a locking nut, which is used to fix the left half mold 5, the right half mold 6 and the support column 7 to ensure stability during the test;

[0053] The locking device 4 is designed with a locking nut. By firmly connecting the left half mold 5, the right half mold 6 and the support column 7, it can effectively prevent loosening due to vibration or tension during the test, and ensure that the tooling always remains stable during the pull-off strength test. The locking device 4 is simple in design, easy to operate and not easy to damage, which effectively improves the reliability and stability of the entire tooling. In addition, the fixing effect of the locking nut can minimize the interference of external environmental factors on the test results, thereby ensuring the accuracy of each test data. This design can effectively improve the service life of the tooling and reduce the maintenance cost caused by looseness.
