Abstract
Description
Technical Field
[0001] This utility model relates to the field of test bench technology, and in particular to an electric vibration test bench with multi-angle clamping function. Background Technology
[0002] In reliability testing of electronic and electrical products, electric vibration test benches are the core equipment for simulating vibration stress, but traditional equipment has significant technical limitations. Existing fixtures are mostly unidirectional or bidirectional structures, relying on manual screws or single cylinders for clamping, which cannot adapt to the complex contours of irregularly shaped components, easily leading to uneven clamping force and specimen displacement and detachment during vibration. Multi-axis testing often relies on combinations of multiple single-axis devices or expensive six-degree-of-freedom vibration tables. The former is inefficient and prone to coupling interference, while the latter is costly, complex to control, and difficult to popularize.
[0003] Meanwhile, the integration of composite environment testing is insufficient, making it difficult to adjust the angle of the specimen synchronously to fit the actual working conditions such as tilting and deflection. This results in a deviation between the test scenario and the real environment. Furthermore, traditional fixtures may lack rigidity or be made of inappropriate materials, which can easily cause resonance or energy loss and affect the test accuracy. Therefore, an electric vibration test bench with multi-angle clamping function is proposed to solve the above problems. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an electric vibration test bench with multi-angle clamping function, which aims to improve the problems of poor clamping adaptation, high cost and test scene deviation in the prior art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An electric vibration test bench with multi-angle clamping function includes a working test bench and a support block. The support block has multiple sliding grooves inside. A multi-angle wheel is rotatably connected inside the support block. Multiple rotating arms are rotatably connected to the outside of the multi-angle wheel. A sliding block is rotatably connected to one end of each rotating arm. A clamping plate is fixedly connected to the outside of each sliding block. A support plate is fixedly connected to the outside of one of the sliding blocks. A cylinder is fixedly connected to the outside of the support plate. A push plate is fixedly connected to the drive end of the cylinder. A rotating assembly for facilitating multi-angle clamping is fixedly connected inside the working test bench.
[0007] As a further description of the above technical solution:
[0008] The rotating assembly includes a motor, one end of which is fixedly connected to the inside of the working test bench, the drive end of which is fixedly connected to a rotating disk, a support shaft is fixedly connected to the outside of the rotating disk, and a wheel groove is provided inside the working test bench.
[0009] As a further description of the above technical solution:
[0010] When the polygonal wheel rotates, it affects the rotation of multiple rotating arms connected to it.
[0011] As a further description of the above technical solution:
[0012] When the cylinder pushes the push plate to move, the reaction force affects the connected support plate to move in the opposite direction to the push plate, thereby controlling the sliding block connected to the push plate and the support plate to move in the opposite direction, transmitting power to the rotating arm, and thus causing the polygonal wheel to rotate.
[0013] As a further description of the above technical solution:
[0014] The function of the groove is to limit the movement trajectory of the sliding block;
[0015] As a further description of the above technical solution:
[0016] One end of the support shaft is fixedly connected to the outside of the support block;
[0017] As a further description of the above technical solution:
[0018] The rotation of the rotating disk controls the circular rotation of the support shaft under the constraint of the wheel groove;
[0019] As a further description of the above technical solution:
[0020] The groove is annular in shape.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, the cylinder serves as the power source, pushing the plate and the support plate to move in opposite directions, thereby causing the sliding block to move radially along the slide groove. The sliding block is driven by the rotating arm to rotate the polygonal wheel. Its "polygonal" structure links all the rotating arms, so that the sliding block drives the clamping plate to synchronously contract and open, achieving stable clamping at multiple angles and ensuring the mechanical constraints of the vibration test.
[0023] 2. In this utility model, the rotating component consists of a motor, a rotating disk, a support shaft, and a wheel groove. The motor drives the rotating disk to rotate, and the support shaft moves circumferentially along the annular wheel groove, causing the clamping system to rotate synchronously, adjusting the orientation of the specimen, and cooperating with the clamping to achieve compound angle testing, simulating complex vibration scenarios.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figures 1 to 4This utility model provides an embodiment of an electric vibration test bench with multi-angle clamping function, including a working test bench 1, which serves as the basic load-bearing structure of the equipment, and a support block 2, which serves as the connection hub between the clamping system and the main body of the test bench. Multiple sliding grooves 3 are provided inside the support block 2 to ensure the precise direction of the clamping force. Multiple angled wheels 4 are rotatably connected inside the support block 2 to synchronously transmit the motion of a single power source to all clamping units. Multiple rotating arms 5 are rotatably connected to the outside of the angled wheels 4 to perform motion conversion and force transmission. When the angled wheels 4 rotate, they affect the rotation of the multiple rotating arms 5 connected to them. A sliding block 6 is rotatably connected to one end of each of the multiple rotating arms 5, serving as the direct execution carrier for the clamping action. The sliding grooves 3 limit the movement trajectory of the sliding block 6.
[0034] A clamping plate 7 is fixedly connected to the outside of the sliding block 6. The clamping plate 7 is designed to apply a stable clamping force to the electronic and electrical products to prevent the specimen from falling off or shifting due to vibration during the test. A support plate 8 is fixedly connected to the outside of one of the sliding blocks 6. The support plate 8 is designed to be the connection node between the power input and the clamping system. A cylinder 9 is fixedly connected to the outside of the support plate 8. The cylinder 9 is designed to provide power for the clamping action. A push plate 10 is fixedly connected to the drive end of the cylinder 9. The push plate 10 is designed to drive the support plate 8 and the corresponding sliding block 6 to move in the opposite direction through the "reaction of force". It is the key transmission component for converting the power of the cylinder 9 into the motion of the clamping system. When the cylinder 9 pushes the push plate 10 to move, due to the reaction of force, it affects the reverse movement of the connected support plate 8 and push plate 10, thereby controlling the reverse movement of the sliding block 6 connected to the push plate 10 and support plate 8, transmitting the power to the rotating arm 5, and thus causing the polygonal wheel 4 to rotate. A rotating component for multi-angle clamping is fixedly connected inside the working test table 1.
[0035] Reference Figure 5 , Figure 6 The rotating component includes a motor 11, which is designed as the power source for the rotating component. One end of the motor 11 is fixedly connected to the inside of the working test bench 1. The drive end of the motor 11 is fixedly connected to a rotating disk 12, which is designed as the drive end of the motor 11 and plays the role of motion conversion and transmission. A support shaft 13 is fixedly connected to the outside of the rotating disk 12. The support shaft 13 is designed as the connecting bridge between the power and clamping systems. One end of the support shaft 13 is fixedly connected to the outside of the support block 2.
[0036] The working test bench 1 has a wheel groove 14 inside. The wheel groove 14 is designed as a ring constraint structure inside the working test bench 1. The rotating disk 12 controls the support shaft 13 to rotate in a ring under the constraint of the wheel groove 14. The wheel groove 14 is ring-shaped.
[0037] Working Principle: The multi-angle clamping electric vibration test bench operates on the following principle: Cylinder 9 serves as the power source, with its drive end connected to push plate 10. Support plate 8 on the opposite side is fixed to another sliding block 6. When cylinder 9 extends or retracts, push plate 10 and support plate 8 move in opposite directions due to the reaction force, causing their respective connected sliding blocks 6 to move radially along the groove 3 inside support block 2. The groove 3 restricts the trajectory of sliding block 6, preventing deflection. Sliding blocks 6 are rotatably connected to polygonal wheels 4 via rotating arms 5. The reverse movement of sliding blocks 6 on both sides causes the corresponding rotating arms 5 to swing in opposite directions, driving polygonal wheels 4 to rotate around the center. The "multi-angle" structure of polygonal wheels 4 allows them to synchronously drive all connected rotating arms 5 to swing during rotation, evenly transmitting power to each rotating arm 5. The other end of each rotating arm 5 is connected to a sliding block 6, which has a clamping plate 7 fixed to its outer side. When the polygonal wheel 4 rotates, all rotating arms 5 swing synchronously, causing the sliding block 6 to contract or open synchronously along the slide groove 3. This allows the clamping plate 7 to apply force to the specimen from angles determined by the number of sides of the polygonal wheel 4, such as four-way or six-way. The system uses the logic of "cylinder 9 driving → polygonal wheel 4 linkage → slide groove 3 constraint → clamping plate 7 synchronous action" to achieve multi-angle, adaptive, and stable clamping of electronic and electrical specimens, providing reliable mechanical constraints for vibration testing and preventing the specimen from loosening or shifting due to uneven clamping.
[0038] The working principle of the rotating assembly of the electric vibration test bench with multi-angle clamping function is as follows: The rotating assembly consists of a motor 11, a rotating disk 12, a support shaft 13, and a wheel groove 14. During operation, the drive end of the motor 11 is connected to the rotating disk 12, and after starting, it drives the rotating disk 12 to rotate around the center. One end of the support shaft 13 is fixed to the support block 2 of the clamping system, and the other end is linked to the rotating disk 12. The wheel groove 14 inside the test bench 1 is annular, which constrains the movement trajectory of the support shaft 13. When the rotating disk 12 rotates, the support shaft 13 moves in a circle along the annular wheel groove 14, thereby pulling the entire support block 2 and the multi-angle wheel 4, clamping plate 7, and other clamping systems above it to rotate synchronously around the central axis. This rotation action can dynamically adjust the spatial orientation of the specimen. Combined with the multi-directional clamping force of the clamping system, it achieves a composite angle testing capability of "fixed clamping angle + overall specimen rotation". The specimen is stably fixed from multiple directions by the clamping plate 7, and the angle between the specimen and the vibration direction is changed by the rotating component. This flexibly simulates the vibration response of electronic and electrical products under different orientations such as tilting and deflection, and expands the coverage of the test bench for complex vibration scenarios.
[0039] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
