Description

Technical Field

[0001] This utility model relates to the field of fatigue testing technology, specifically a fatigue testing mechanism for logistics components. Background Technology

[0002] In the logistics industry, linear guide sliders are widely used in various logistics equipment, such as automated sorting systems and warehouse racking handling equipment. During daily operation, these linear guide sliders need to withstand frequent reciprocating motions and large loads, which can easily lead to fatigue wear, thereby affecting the normal operation and service life of the logistics equipment. Therefore, in order to ensure the performance of linear guide sliders, fatigue tests are usually required.

[0003] However, existing fatigue testing institutions can usually only test one set of linear slide rails during use. When multiple sets of linear slide rails need to be tested, they often need to be tested one by one, which makes the entire testing process take a long time, thus seriously affecting the efficiency of fatigue testing and failing to meet the needs of users. Utility Model Content

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0022] Example 1:

[0023] Please see Figures 1-4 As shown, this utility model provides a fatigue testing mechanism for logistics components, including a test bench 1. A fixed frame 5 is fixedly connected to the right side of the inner cavity of the test bench 1. A drive motor 6 is fixedly installed on the upper left side of the fixed frame 5. A first bevel gear 7 is fixedly installed at the output end of the drive motor 6. A rotating shaft 9 is movably connected to the top of the fixed frame 5 through a bearing. A second bevel gear 8 is fixedly installed at the bottom of the rotating shaft 9. A U-shaped rotating rod 10 is fixedly connected to the top of the rotating shaft 9. A connecting plate 12 is movably connected to the middle end of the U-shaped rotating rod 10 through a bearing. A U-shaped connecting frame 4 is movably connected to the left end of the connecting plate 12 through a bearing. A connecting horizontal plate 2 is slidably connected to the upper end of the U-shaped connecting frame 4. Guide columns 16 are fixedly connected to both ends of the top of the connecting horizontal plate 2. There are six guide columns 16. An adjusting screw 18 is threadedly connected to the lower end of the guide column 16. A limit baffle 19 is movably connected to the surface of the adjusting screw 18 through a bearing.

[0024] In this technical solution, the test bench 1 supports multiple sets of linear slide rail sliders required for logistics testing. The guide column 16, adjusting screw 18, and limiting baffle 19 limit the movement between the connecting plate 2 and the slider during testing, ensuring that the connecting plate 2 can move the slider during subsequent movement. Through the coordinated action of the drive motor 6, the first bevel gear 7, the second bevel gear 8, the rotating shaft 9, the U-shaped rotating rod 10, the connecting plate 12, the U-shaped connecting frame 4, the connecting plate 2, and the limiting baffle 19, the slider is pushed to reciprocate along the surface of the linear slide rail during testing. This achieves the effect of synchronous fatigue testing of multiple sets of linear slide rail sliders. The overall operation is convenient and quick, effectively improving the efficiency of fatigue testing and greatly meeting the needs of personnel.

[0025] Example 2:

[0026] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a support plate 15 is slidably connected between the upper ends of two guide columns 16. A support column 13 is fixedly connected to the middle end of the support plate 15. A counterweight plate 14 is slidably connected to the upper end of the support column 13. The bottom of the counterweight plate 14 is placed on the top of the support plate 15. A guide crossbar 17 is fixedly connected to the upper end of the limiting baffle 19. The surface of the guide crossbar 17 is slidably connected to the surface of the guide column 16. Guide slide rods 3 are fixedly connected to both ends of the top of the test bench 1. The surface of the U-shaped connecting frame 4 is slidably connected to the surface of the guide slide rod 3. A support shaft 11 is fixedly connected to the left end of the top of the U-shaped rotating rod 10. The top of the support shaft 11 is movably connected to the right end of the top of the inner cavity of the test bench 1 through a bearing. The first bevel gear 7 meshes with the second bevel gear 8. A maintenance plate is fixedly installed on the front surface of the test bench 1 by bolts. The maintenance plate is rectangular in shape.

[0027] In this technical solution, the support plate 15, support column 13, and counterweight plate 14 are configured so that the support column 13 can contact the top of the slider during the test and apply counterweight to the top of the slider. This allows personnel to perform the test under load on the slider, improving the accuracy of fatigue testing. The guide bar 17 guides the limit baffle 19, preventing it from tilting during movement. The guide slide bar 3 guides the U-shaped connecting frame 4, preventing it from tilting during movement. The support shaft 11 supports the top of the U-shaped rotating rod 10, preventing it from tilting due to force.

[0028] The working principle of this utility model is as follows: After installing multiple sets of linear slide rail sliders required for testing in logistics components onto the top of the test bench 1, the connecting horizontal plate 2 is placed on top of the multiple sets of sliders and inserted into the upper end of the U-shaped connecting frame 4. Then, by manipulating the adjusting screw 18 to rotate, the limiting baffle 19 is moved, so that the limiting baffle 19 can contact both sides of the slider, thereby limiting the distance between the connecting horizontal plate 2 and the slider, ensuring that the connecting horizontal plate 2 can drive the slider to move during subsequent movement. Subsequently, the drive motor 6 is started by the external controller, which drives the first bevel gear 7 to rotate. The rotation of the first bevel gear 7 drives the second bevel gear 8 and the rotating shaft. The U-shaped rotating rod 10 and the U-shaped rotating rod 10 rotate, which drives the U-shaped connecting frame 4 to reciprocate in the left and right horizontal directions through the connecting plate 12. The movement of the U-shaped connecting frame 4 drives the connecting horizontal plate 2 to move. The movement of the connecting horizontal plate 2 drives the slider to reciprocate along the surface of the linear slide rail through the limit baffle 19. After the linear slide rail slider has run for a certain period of time, the personnel can disassemble the linear slide rail slider and use tools to measure the gap and the resistance generated when the linear slide rail slider slides slide together. This achieves the effect of synchronous fatigue testing of multiple sets of linear slide rail sliders. The overall operation is convenient and quick, effectively improving the efficiency of fatigue testing and greatly meeting the needs of personnel.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
