Description

A multi-functional high-speed train locomotive large spring multi-directional fatigue loading test system Technical Field

[0001] This utility model belongs to the field of spring fatigue loading technology, and in particular relates to a multi-functional high-speed locomotive large spring multi-directional fatigue loading test system. Background Technology

[0002] The main purpose of spring fatigue loading test is to determine how many cycles of loading a spring can withstand under specific working conditions without breaking or significantly degrading its performance. This test can provide key data for spring design, material selection and quality control, ensuring that the spring has sufficient life and reliability in practical applications, and providing strong protection for product quality and safety.

[0003] In common fatigue loading tests, springs are subjected to variable-amplitude loads, and their parameters are recorded. However, in actual use, the applied force is limited to a single direction, and the spring is prone to displacement during loading, affecting the test results. Therefore, we provide a multi-functional high-speed train locomotive large spring multi-directional fatigue loading test system to solve the aforementioned technical problems. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a multi-functional high-speed train locomotive large spring multi-directional fatigue loading test system, including a loading support assembly. The loading support assembly includes a loading support platform, two vertical actuators symmetrically arranged above the loading support platform, and a horizontal actuator installed on the upper surface of the loading support platform. Two loading test components are snapped together on the upper surface of the loading support platform, one of which is placed horizontally and the other is placed vertically. Each loading test component includes a test pressure plate that can move up and down. A limit component is fixedly installed on the upper surface of the loading test component. The limit component includes several horizontally movable transmission support blocks, and a limit clamping plate is fixedly connected to the upper surface of the transmission support blocks through a support column.

[0006] The present invention is further configured such that two vertical support seats are symmetrically fixedly connected to the upper surface of the loading support platform, and a horizontal support platform is fixedly connected between the two vertical support seats. Two adjustable support plates are symmetrically slidably arranged on both sides of the horizontal support platform, and adjacent adjustable support plates are connected by adjustable mounting columns. The vertical actuator is fixedly installed on the lower surface of the corresponding adjustable support plate, and a loading transmission block is fixedly connected to the output end of the vertical actuator. The loading transmission block is rotatably connected to hinge seats on both sides, and the hinge seats are fixedly connected to the upper surface of the corresponding test pressure plate.

[0007] The present invention is further configured such that the loading test assembly includes a test support platform that is snapped together with the loading support platform. Two hollow support seats are symmetrically fixedly connected to opposite sides of the test support platform. A transverse support seat can be connected between two adjacent hollow support seats. A guide slide is provided on one side of the hollow support seat. The test pressure plate is slidably disposed between the hollow support seats through an extension block. The extension block is slidably engaged with the corresponding guide slide. An electromagnet is fixedly connected to the upper surface of the hollow support seat. A magnet is fixedly connected to the upper surface of the extension block. The test support platform of the loading test assembly, which is placed vertically, is fixedly connected to the output end of the horizontal actuator.

[0008] The present invention is further configured such that the limiting component includes a hollow limiting platform fixedly connected to the upper surface of the test support platform. A plurality of transmission external gear rings are rotatably connected to the bottom of the hollow limiting platform. A plurality of limiting adjustment grooves are symmetrically opened on the surface of the transmission external gear rings. One inner sidewall of the limiting adjustment groove is an inclined sliding surface structure. One end of the transmission support block is slidably engaged with the corresponding limiting adjustment groove. A partition block corresponding to each limiting adjustment groove is rotatably connected to the inner sidewall of the transmission external gear ring. The partition block is fixedly connected to the bottom of the hollow limiting platform. A limiting channel is formed between two adjacent partition blocks. A limiting support block is fixedly connected inside the limiting channel.

[0009] The present invention is further configured such that a guide column is slidably disposed on the surface of the limiting support block, the transmission support block is fixedly connected to the corresponding guide column, a return spring is fixedly connected between the transmission support block and the limiting support block, and the return spring is sleeved on the outside of the guide column; a limiting transmission rack is slidably disposed at the bottom of the hollow limiting platform, the limiting transmission rack meshes with the transmission outer gear ring, and a limiting slide rail corresponding to the transmission outer gear ring is opened on the upper surface of the hollow limiting platform, and the support column slides in cooperation with the corresponding limiting slide rail.

[0010] The present invention has the following beneficial effects: 1. By setting up a loading support assembly and a loading test assembly, the spring to be tested is placed on the horizontally placed and vertically placed loading test assemblies respectively. The vertical actuator drives the test pressure plate to move downward, and the horizontal actuator drives the corresponding test support platform to move horizontally, thereby realizing the horizontal and vertical fatigue loading test, so as to carry out multiple fatigue loading tests.

[0011] 2. This utility model sets up a limiting component to control the horizontal movement of the limiting transmission rack, which drives the transmission outer gear ring to rotate synchronously. Under the sliding cooperation between the limiting adjustment groove and the transmission support block, the transmission support block moves horizontally, which in turn drives the limiting clamping plate to move synchronously and move closer to each other until the limiting clamping plate is in contact with the peripheral side of the spring. This achieves the limitation of the spring's position and avoids the spring's movement during the loading test from affecting the test results. Attached Figure Description

[0026] The operation process of this embodiment is as follows: The spring to be tested is placed on the horizontally placed and vertically placed loading test components 2 respectively. The transmission support block 301 is controlled to move horizontally, driving the limiting clamping plate 302 to move synchronously until the limiting clamping plate 302 is in contact with the peripheral side of the spring.

[0029] Furthermore, the limiting component 3 also includes a hollow limiting platform 303 fixedly connected to the upper surface of the test support platform 202. Several transmission external gear rings 304 are rotatably connected to the bottom of the hollow limiting platform 303. Several limiting adjustment grooves 305 are symmetrically opened on the surface of the transmission external gear rings 304. One inner sidewall of the limiting adjustment groove 305 is an inclined sliding surface structure. One end of the transmission support block 301 is in sliding fit with the corresponding limiting adjustment groove 305. The inner sidewall of the transmission external gear ring 304 is rotatably connected to a partition block 306 corresponding to the limiting adjustment groove 305. The partition block 306 is fixedly connected to the bottom of the hollow limiting platform 303. A limiting channel is formed between two adjacent partition blocks 306. A limiting support block 307 is fixedly connected inside the limiting channel.

[0030] Furthermore, a guide column 308 is slidably provided on the surface of the limiting support block 307, and the transmission support block 301 is fixedly connected to the corresponding guide column 308. A return spring 309 is fixedly connected between the transmission support block 301 and the limiting support block 307, and the return spring 309 is sleeved on the outside of the guide column 308. A limiting transmission rack 310 is slidably provided at the bottom of the hollow limiting platform 303. The limiting transmission rack 310 meshes with the transmission outer gear ring 304.

[0031] The operation process of this embodiment is as follows: The springs to be tested are placed on the horizontally placed and vertically placed hollow limiting platforms 303 respectively. The electric telescopic rod is activated to drive the limiting transmission rack 310 to move horizontally. Under the meshing action of the limiting transmission rack 310 and the transmission outer gear ring 304, the transmission outer gear ring 304 rotates synchronously, thereby driving the limiting adjustment groove 305 to move synchronously. Under the sliding cooperation between the inclined sliding surface of the limiting adjustment groove 305 and the corresponding transmission support block 301, the transmission support block 301 moves horizontally, and the support column slides along the inside of the corresponding limiting slide rail 311, thereby driving the limiting clamping plates 302 to move synchronously and move closer to each other. The guide column 308 moves horizontally synchronously, and the return spring 309 is compressed until the limiting clamping plate 302 is in contact with the circumferential side of the spring, thereby limiting the position of the spring. The electromagnet 206 is disconnected, and the magnetic effect between the electromagnet 206 and the magnetic attractor 207 disappears. The two vertical actuators 102 drive the two test pressure plates 201 to move downward synchronously. The test pressure plates 201 press down on the spring to perform a longitudinal fatigue loading test. The horizontal actuator is controlled to drive the longitudinally placed loading test assembly 2 to move, and the corresponding test support platform 202 moves horizontally, thereby driving the spring on the loading test assembly 2 to move horizontally synchronously, thereby performing a transverse fatigue loading test.
