Description

Technical Field

[0001] This utility model relates to the field of vibration tables, specifically to a vibration table for simulating transportation. Background Technology

[0002] A vibration table is a testing device used in laboratory environments to simulate the vibration and impact experienced by products during transportation. It generates controllable vibrations through a motor drive or hydraulic system to reproduce the bumps and vibrations of transportation scenarios such as highways, railways, and aviation. It is mainly used to test the integrity of packaging, the structural strength of products, and the reliability of electronic components, and to expose potential faults in advance to optimize the design.

[0003] In existing transportation vibration simulation technologies, most devices can only generate vibration simulations in a single direction. They cannot simultaneously simulate the vibrations of goods in the vertical direction caused by bumps and the vibrations in the horizontal direction during transportation. This makes it difficult to fully and realistically reproduce the transportation vibration environment, which may lead to inaccurate assessments of the vibration resistance performance of transported goods in real transportation scenarios. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned shortcomings by providing a simulated transportation vibration table that can simulate the horizontal vibration of goods during transportation. By combining vertical and horizontal vibration simulation, it can more comprehensively and realistically simulate the transportation vibration environment. This solves the technical problem that existing technologies cannot simultaneously simulate both the vertical vibration caused by bumps and the horizontal vibration of goods during transportation, making it difficult to fully and realistically reproduce the transportation vibration environment. This may lead to inaccurate assessment of the vibration resistance performance of transported goods in real transportation scenarios.

[0005] The objective of this utility model is achieved through the following means:

[0006] A simulated transport vibration table includes a vibration table support, a vibration frame mounted on top of the support, slide rails mounted on both the front and rear sides of the upper surface of the vibration frame, a vibration seat mounted on the upper surface of the slide rails, an mounting plate mounted on the upper surface of the base plate of the support, a first motor mounted on the surface of the mounting plate, a rotating rod coaxially mounted on the rotor of the first motor, cams evenly distributed on the surface of the rotating rod, an installation groove formed on the upper surface of the vibration frame, a second motor mounted inside the installation groove, a turntable coaxially mounted on the rotor of the second motor, a first connecting plate mounted on the surface of the turntable via a rotating shaft, a second connecting plate mounted on the connecting end of the first connecting plate via a rotating shaft, and the second connecting plate connected to the surface of the vibration seat.

[0007] Furthermore, a return spring is installed at each of the four corners of the upper surface of the base plate of the vibration table support. The top of each return spring is connected to the bottom of the vibration frame. The return spring can support the vibration frame, allowing the vibration frame to be in close contact with the upper surface of the cam and to rise and fall with the cam.

[0008] Furthermore, lifting blocks are installed on both the left and right sides of the vibration frame, and lifting slots are opened on the surface of the vibration table support at positions corresponding to the lifting blocks. The lifting blocks are inserted into the lifting slots, enabling the vibration frame to be raised and lowered.

[0009] Furthermore, a limiting sleeve is installed inside the mounting groove, and the second connecting plate is inserted into the limiting sleeve, allowing the second connecting plate to move linearly.

[0010] Furthermore, mounting brackets are installed on both the front and rear sides of the upper surface of the vibration seat, and cylinders are installed on the surface of each mounting bracket. Clamping plates are installed on the output ends of each cylinder. Activating the cylinder can drive the clamping plates to clamp the sample.

[0011] Furthermore, each of the vibration seats is equipped with a first slide bar at its bottom. Each first slide bar has a mounting frame on its front side. A pull-out plate is inserted into the surface of each mounting frame. A second slide bar is installed at the connecting end of each pull-out plate. A compression spring is installed between the second slide bar and the inner wall of the mounting frame. The first and second slide bars are movably mounted in the groove of the slide rail. The pull-out plate allows the second slide bar to be pulled out from the groove of the slide rail, facilitating the disassembly of the vibration seat. When the pull-out plate is released, the second slide bar is inserted into the groove of the slide rail under the action of the compression spring, further facilitating the assembly and disassembly of the vibration seat. Since the second slide bar is inserted into the interior of the mounting frame, it prevents the second slide bar from shifting.

[0012] The beneficial effects of this invention are as follows: The added first motor drives the rotating rod and cam to rotate. The cam interacts with the vibration frame to generate vertical vibration, simulating the bumpy vibration during transportation. The second motor installed in the groove on the vibration frame drives the turntable to rotate. The turntable is connected to the first connecting plate and the second connecting plate in sequence through a rotating shaft. The second connecting plate is connected to the vibration seat, which can convert the circular motion of the turntable into the reciprocating motion of the vibration seat in the horizontal direction or a specific trajectory. This can simulate the horizontal vibration of the goods during transportation. By combining vertical and horizontal vibration simulation, the vibration environment of transportation can be simulated more comprehensively and realistically, and the vibration resistance performance in real transportation scenarios can be evaluated more accurately.

[0020] The vibration table support 1 provides stable support for the overall structure. The vibration frame 2 above it cooperates with the vibration seat 4 through the slide rail 3, allowing the vibration seat 4 to move along the slide rail 3 and providing basic guidance for vibration. The first motor 6 on the mounting plate 5 drives the rotating rod 7 and cam 8 to rotate. The cam 8 interacts with the vibration frame 2 to generate vertical vibration, simulating the bumpy vibration during transportation. The second motor 10 in the mounting slot 9 on the vibration frame 2 drives the turntable 11 to rotate. The turntable 11 is connected to the first connecting plate 12 and the second connecting plate 13 in sequence through the rotating shaft. The second connecting plate 13 is connected to the vibration seat 4. This structure can convert the circular motion of the turntable 11 into the reciprocating motion of the vibration seat 4 in the horizontal direction or along a specific trajectory, thereby simulating the horizontal vibration of the goods during transportation. By combining vertical and horizontal vibration simulation, it more comprehensively and realistically simulates the vibration environment during transportation.

[0029] The first slide bar 21 and the second slide bar 24 are movably installed in the groove of the slide rail 3. The second slide bar 24 can be pulled out from the groove of the slide rail 3 by the pull plate 23, so that the vibrating seat 4 can be easily disassembled. When the pull plate 23 is released, the second slide bar 24 will be inserted into the groove of the slide rail 3 under the action of the compression spring 25, so that the vibrating seat 4 can be easily disassembled and assembled. The second slide bar 24 is inserted into the inside of the mounting frame 22, which can prevent the second slide bar 24 from shifting, so as to realize the quick installation and position adjustment of the equipment without relying on complicated tools to disassemble and assemble the vibrating seat 4.

[0030] The working process of a simulated transport vibration table in this embodiment is as follows: The vibration table support 1 provides stable support, and the return springs 14 at the four corners of its base plate support the vibration frame 2 in close contact with the cam 8. The first motor 6 drives the rotating rod 7 and the cam 8 to rotate, so that the vibration frame 2 is raised and lowered under the cooperation of the lifting block 15 and the lifting groove 16, generating vertical vibration; at the same time, the second motor 10 in the mounting groove 9 on the vibration frame 2 drives the turntable 11 to rotate, and through the first connecting plate 12 and the second connecting plate 13, the second connecting plate 13 inserts into the limiting sleeve 17 and moves linearly to drive the vibration seat 4 to move horizontally or along a specific trajectory; the cylinder 19 of the mounting frame 18 on the vibration seat 4 drives the clamping plate 20 to clamp the sample; and the first slide bar 21 and the second slide bar 24 at the bottom of the vibration seat 4 are movably installed in the groove of the slide rail 3, and the vibration seat 4 can be easily disassembled and assembled by pulling the pull plate 23.
