Description

Technical Field

[0001] The utility model relates to the technical field of vibration testing, in particular to a vibration testing tray device. Background Art

[0002] A vibration test pallet is a device used to perform vibration tests on products, usually to simulate the vibration environment that the product may encounter during transportation, use or storage. These pallets are usually made of strong materials to ensure that they can withstand the forces and pressures during vibration testing.

[0003] After searching, the patent document with announcement number: CN217321209U discloses a vibration test tray device, which relates to the field of vibration test technology. The vibration test tray device includes a fixed tray, the interior of the fixed tray is slidably connected to a placement box, and both sides of the interior of the placement box are provided with fixed components, and the fixed components are used to fix the test device; the lower ends of both sides of the placement box are fixed with slide rails, and both sides of the inner wall of the fixed tray are fixed with slide grooves at positions corresponding to the slide rails. The utility model adopts a multi-structure matching design, so that the device can take out the placement box from the interior of the fixed tray by pulling, and after the placement box is placed inside the fixed tray, it is fixed by the snapping of the card seat and the card block. Its structure is relatively simple, making it more convenient to take and put the test device; through the structural design of the fixed component, when the test device is placed inside the placement box, the test device is automatically fixed by squeezing, which effectively reduces the time required for fixation and improves the efficiency of the test.

[0004] The above patent mentioned in the specification that "when the test device is placed inside the placement box 4, the upper end of the extrusion plate 10 contacts the bottom of the test device, so that the extrusion plate 10 drives the sliding seat 11 to move in the direction of the fixed seat 12 and squeezes the fixed spring 13. Through the elastic deformation of the fixed spring 13, when the fixed spring 13 is squeezed, an opposite force is continuously applied in the force direction. After the test device is completely placed inside the placement box 4, the sliding seat 11 is pushed by the fixed spring 13 to squeeze the test device and complete the fixation." However, in the actual use process, because the sizes of the objects are inconsistent and the elastic force of the spring is fixed, it will lead to the inability to fix the objects of different sizes well, resulting in the unprepared test data.

[0026] One end of spring 17 is fixedly connected to the inner wall of one side of groove 12, and the other end of spring 17 is fixedly connected to one side of sliding block 8. When sliding block 8 moves, spring 17 can be squeezed to deform spring 17 and generate elastic potential energy. One side of sliding block 8 is rotatably connected with connecting rod 9, and when sliding block 8 moves, it can rotate with connecting rod 9. One end of connecting rod 9 away from sliding block 8 is rotatably connected with pushing plate 10, and the pushing plate 10 can be moved by the rotation of connecting rod 9. The outer part of sliding block 8 is slidably connected to the inner wall of groove 12, and the outer part of pushing plate 10 is slidably connected to the inner wall of groove 12, so that pushing plate 10 can be restricted by groove 12. The inner side wall of pushing plate 10 is fixedly connected with clamping block 11, and objects are clamped by clamping block 11. The outer part of clamping block 11 is slidably connected to the inner wall of moving plate 5, and pushing plate 10 can be pushed by clamping block 11. The front end of the inner wall of fixed tray 3 is fixedly connected with limiting rod 13.

[0027] The through hole of the moving plate 5 is slidably connected to the outside of the limiting rod 13. By limiting the moving plate 5 by the limiting rod 13, the moving plate 5 can be more stable when moving. The left end of the two-way threaded rod 4 is fixedly connected with a handle 14, and the two-way threaded rod 4 can be controlled to rotate by the handle 14. The front inner wall of the housing 1 is fixedly connected with a driving assembly. The driving assembly includes a motor 15 and an elliptical disk 16. The front end of the motor 15 is fixedly connected to the front inner wall of the housing 1, so that the motor 15 can be stable. The front end of the elliptical disk 16 is fixedly connected to the driving end of the motor 15. When the motor 15 is started, the elliptical disk 16 can be rotated with the motor 15. The outside of the elliptical disk 16 contacts the bottom of the sliding plate 2. The sliding plate 2 can be hit by the rotation of the elliptical disk 16, so that the sliding plate 2 vibrates.

[0028] refer to Figure 2 and Figure 4The inner walls of the four corners of the bottom of the housing 1 are fixedly connected with support rods 17, the outer sleeve of the support rod 17 is provided with a spring 18, the top of the support rod 17 is fixedly connected with an extrusion block 19, and the extrusion block 19 can be used for restriction. The outer sliding connection of the support rod 17 is connected with a shell 20, and the top of the shell 20 is fixedly connected to the bottom of the sliding plate 2. This is for connection, so that the sliding plate 2 can move with the shell 20 when moving. The shell 20 has a slide groove 21 inside, and the outer sliding connection of the extrusion block 19 is connected to the inner wall of the slide groove 21, and the sliding of the extrusion block 19 is limited by the slide groove 21. One end of the spring 18 is fixedly connected to one side of the extrusion block 19, and the other end of the spring 18 is fixedly connected to the inner wall of one side of the slide groove 21. The movement of the shell 20 can adjust the space of the slide groove 21, so that the spring 18 is squeezed, and the sliding plate 2 can be quickly reset during the vibration process.

[0029] Working principle: When the device needs to be used, the items that need to be vibrated are placed inside the fixed tray 3. At this time, the handle 14 is turned, and the rotation of the handle 14 can lead the bidirectional threaded rod 4 to rotate. The rotation of the bidirectional threaded rod 4 makes the movable plate 5 move, and the movement of the movable plate 5 can lead the clamping block 11 to move. The movement of the clamping block 11 can clamp and fix the items that need to be tested. In the process of clamping and fixing, the clamping block 11 will push the pushing plate 10, so that the pushing plate 10 moves on the inner wall of the groove 12. At this time, the movement of the pushing plate 10 can lead the connecting rod 9 to rotate, and the connecting rod 9 can push the sliding block 8 to move during the rotation, so that the spring 7 is deformed to generate elastic potential energy, so that the clamping block 11 can increase the clamping force of the item.

[0030] After clamping, start the motor 15 again. When the motor 15 is started, the elliptical disk 16 can be rotated. The continuous rotation of the elliptical disk 16 can hit the sliding plate 2, so that the sliding plate 2 pushes the fixed tray 3, so that the items inside the fixed tray 3 are subjected to vibration, so as to carry out the test. In the process of the movement of the sliding plate 2, the shell 20 can be moved, and the movement of the shell 20 outside the support rod 17 can make the extrusion block 19 slide on the inner wall of the slide groove 21, so that the spring 2 18 is squeezed. When the spring 2 18 is squeezed, the sliding plate 2 can be moved better, so that the vibration test of the item can be better carried out.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
