Description

Technical Field

[0001] This invention relates to the field of vibration testing equipment for connecting pieces, and in particular to a connecting piece toggle vibration simulation testing device and testing method. Background Technology

[0002] Currently, power tools and other equipment generate continuous vibration, impact, and cyclic loads during operation. Connecting plates, serving as components for current transmission, signal acquisition, or structural connection, are typically fixed at one or more ends by welding, riveting, screwing, or clamping, while the other part vibrates slightly or bends with the overall machine's vibration. After prolonged use, connecting plates are prone to fatigue cracks, fractures, and poor contact at bends, around fixing holes, in weld heat-affected zones, or in material transition areas.

[0003] Existing verification methods mostly employ general-purpose vibration tables, manual repeated bending, or single-station fatigue testing. General-purpose vibration tables are closer to overall excitation, but they are difficult to reliably reproduce the stress pattern of connecting pieces being locally moved and repeatedly bent under actual installation conditions; manual bending has poor consistency and is difficult to count; single-station equipment has low testing efficiency and insufficient comparability between different parts and different installation conditions.

[0004] Existing technical pain points: 1. It is difficult to simulate the local vibration, swaying and repeated bending of the connecting piece during actual operation using low-cost equipment.

[0005] 2. When multiple connector samples need to be compared simultaneously, traditional methods have long testing cycles and insufficient consistency of operating conditions.

[0006] 3. During the testing process, data such as the number of connector failures, test duration, and lifespan at different workstations rely on manual recording, which is prone to omissions or errors.

[0007] 4. The fixture lacks versatility. When dealing with connecting pieces of different lengths, widths, fixed hole positions, or bending angles, it is necessary to frequently make special tooling.

[0008] 5. Open-ended repeated tossing tests pose a risk of sample ejection, breakage and splashing, or accidental contact by personnel.

[0009] To address these issues, we developed a connecting piece toggle vibration simulation testing device and method. Summary of the Invention

[0010] The purpose of this invention is to overcome the shortcomings of the prior art by providing a connecting piece toggle vibration simulation test device and test method, which has the advantages of improving verification efficiency, improving the universality of in-plant testing, reducing costs, improving traceability, improving safety, and facilitating operation.

[0011] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a connecting piece toggle vibration simulation testing device, comprising a chassis base, a testing platform at the top of the chassis base, a turntable at the middle of the testing platform, multiple sets of clamping components fixedly connected to the top of the turntable, and multiple sets of toggle components evenly distributed around the turntable, the clamping components clamping the connecting piece, a servo motor movably connected to the bottom of the turntable, the servo motor being fixedly connected to the testing platform, the bottom of the toggle components being fixedly connected to the testing platform, a transparent protective cover movably covering the top of the testing platform, and a slotted sensor fixedly connected to the top of the top, a control panel fixedly connected to the side wall of the transparent protective cover, and control buttons provided on the side wall of the chassis base, the control buttons being electrically connected to the control panel, the servo motor, and the slotted sensor respectively.

[0015] Preferably, the clamping assembly includes a fixing block and a pressing block. The fixing block has an L-shaped notch at one corner, and the L-shaped notch is adjustablely connected to the pressing block. A connecting piece is pressed between the fixing block and the pressing block.

[0016] Preferably, a fixing hole is provided at the bottom end of the L-shaped notch, and a second adjustment hole is provided at the top end of the clamping block, and the fixing hole is fixedly connected to the second adjustment hole.
