[0002] Elastic pads are a set of support devices used for the cross-end of railway freight cars. Elastic pads need to undergo combined compression deformation and fatigue performance tests. The requirements for the elastic pad combination are as follows: according to the product technical requirements, two qualified test pieces are randomly selected and assembled into a set of components using high-strength bolts (M24). The tightening torque is 675N·m. After the samples are assembled, the combined compression deformation test at room temperature is completed within 30 minutes.

[0006] Furthermore, a crossbeam is provided at the bottom of the cylindrical base.
[0007] Furthermore, the baffle is a long I-shaped structure.
[0008] Furthermore, the sleeve is a hexagonal sleeve, and a hexagonal hole is designed inside the hexagonal sleeve.

[0024] Example 1
[0025] like Figure 1-Figure 3 As shown:
[0026] An assembly tool for elastic pad combination testing, comprising a cylindrical base 1, a retaining bar 2 and a hexagonal socket 3, wherein:
[0027] The cylindrical base 1 has a sleeve structure in appearance. A hexagonal positioning boss 101 is provided at the bottom center of the cylindrical base 1. A crossbeam 102 with sufficient strength is provided at the bottom of the hexagonal positioning boss 101. The crossbeam 102 is connected to the cylindrical base 1. A groove 103 is provided at the top of the cylindrical base 1, and the groove 103 is used to place the baffle 2.
[0028] The cylindrical base 1 is the main part of the entire tooling. Its appearance is designed as a sleeve structure with high structural rigidity and strength. Its size is closely related to the stability of the overall tooling. The inner diameter of the cylindrical base 1 is 192mm and the height is 200mm. The specific specifications may match the size of the elastic pad to be tested. The hexagonal positioning boss 101 is designed as a hexagon and has a very good mechanical locking function, which can make the hexagonal socket 3 tightly fixed in the base to avoid loosening due to external forces during the test. This design enhances the accuracy and stability of the tooling. The crossbeam 102 is used to bear large pressure or torque, especially lateral or longitudinal forces that may be generated during the test. The crossbeam 102 must have sufficient strength to prevent deformation or damage, thereby ensuring the long-term reliability of the tooling.
[0029] The retaining bar 2 is a long strip-shaped stopper, and the size of the retaining bar 2 matches the groove 103 at the top of the cylindrical base 1. The retaining bar 2 is inserted into the groove at the top of the cylindrical base 1 to support the reaction arm of the torque wrench.
[0030] The groove on the top of the cylindrical base 1 ensures the precise positioning of the baffle, so that during the assembly process, the baffle will not be offset or misaligned, thereby improving the operating accuracy.
[0031] The retaining bar 2 is I-shaped, with its vertical surface parallel to the axial direction of the cylindrical base 1. The retaining bar 2 is inserted into the groove at the top of the cylindrical base 1. This I-shaped structure provides good bending resistance and effectively disperses the reverse force from test equipment (such as a torque wrench) during operation. Its shape also mates well with the groove of the cylindrical base, ensuring stability.
[0032] The hexagonal socket 3 is a cylindrical hollow ring with a hexagonal hole designed inside. The hexagonal socket 3 is used in conjunction with the size of the hexagonal positioning boss 101 at the bottom of the cylindrical base 1. The height of the hexagonal socket 3 should be higher than the height of the hexagonal positioning boss 101 at the center of the bottom of the cylindrical base 1.
[0033] The hexagon socket 3 is designed to quickly and accurately engage the locating boss on the cylindrical base 1, ensuring excellent assembly precision and ease of use. The hexagon socket accepts standard hexagonal tools (such as hexagonal wrenches), providing greater torque transmission capacity. The hexagon socket is sized to perfectly align with the locating boss on the base to ensure stability during testing.
[0034] The hollow cylindrical structure of the hexagonal socket 3 may be designed to reduce weight and unnecessary material usage, and may also be designed to reduce friction and wear during the use of the tooling and ensure the long-term stability of the tooling.
[0035] The hexagonal positioning boss of the cylindrical base of this utility model fits tightly with the hexagonal socket of the hexagonal socket. This design ensures a secure connection between the various components during the experiment, preventing potential motion deviation and error transmission. The entire tooling design emphasizes ease of operation. Through a simple fit and plug-in structure, experimenters can complete assembly and disassembly in a short time without the use of complex tools or operating procedures. This is of great significance for improving experimental efficiency, reducing labor costs, and minimizing operational errors.
[0036] The operating procedures of the utility model assembly tool:
[0037] First, place the cylindrical base 1 on the workbench and ensure that the base is stable and not loose.
[0038] Insert the retaining bar 2 into the groove on the top of the cylindrical base 1, ensuring that the retaining bar is fully embedded and fixed.
[0039] The hexagon socket 3 is docked with the hexagonal positioning boss at the bottom of the cylindrical base 1 and locked with a hexagonal tool to ensure its stability.
[0040] Conducting Tests: Once the tooling is installed, experimental operations such as assembly, testing, or fatigue testing of the spring pad can begin. Because the tooling design makes the entire assembly process simple and efficient, the experimenter can quickly enter the test state without wasting too much time on complex assembly or debugging.
[0041] This assembly tool is designed to facilitate the rapid assembly and disassembly of elastic pads through efficient assembly, thereby improving experimental efficiency and accuracy. Given the importance of elastic pads in testing, which often involves high torque operations and the need to avoid errors or loosening of the tool, the stability, strength, and precision of this assembly tool are crucial.
[0042] The utility model ensures the rapid completion of the elastic pad combination test, reduces human operation errors, and avoids repeated operations or incorrect adjustments caused by unstable tooling. By simplifying the assembly process of the test equipment, the experimenter can focus more on the test itself, improving the overall experimental efficiency. The test process of the elastic pad usually involves high-intensity operations, especially in fatigue tests, where the operation frequency and intensity are large. Through reasonable tooling design, the physical exertion of the operator can be reduced, making the experimental process easier and more efficient. Compared with complex multifunctional experimental equipment, the utility model has a simple tooling design, is easy to manufacture, and has a low cost. Utilizing existing processing technology, it can be quickly produced and put into use to meet the needs of experiments of different scales.
[0043] The utility model of the assembly tool for elastic pad combination test can make the elastic pad test combination process faster and more convenient, reduce the labor intensity of the combination experimenter, and improve the efficiency of the elastic pad combination test and fatigue test. The design structure is simple, light and compact, easy to process and easy to operate.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
