Description

Technical Field

[0001] This utility model belongs to the field of strength testing technology, and in particular relates to a protective device for strength testing of mechanical parts. Background Technology

[0002] Mechanical components are indispensable parts of a machine, working in conjunction with other components to achieve specific functions. The various parts of a mechanical component have defined relative motion relationships, precisely set according to the machine's design requirements and working principles. After manufacturing, these relationships are often tested for strength.

[0003] A search revealed a strength testing device for machining mechanical parts, with publication number CN220120572U. However, existing strength testing devices cause mechanical parts to deform under external pressure during testing, resulting in parts scattering and potentially injuring nearby workers, posing a significant danger and hindering equipment use. Furthermore, after testing, some structural components easily fall onto the placement base, requiring manual cleaning by workers, which is inconvenient and severely reduces work efficiency.

[0004] To address these issues, we provide a protective device for strength testing of mechanical parts. Utility Model Content
