Abstract

The invention discloses a spring fatigue test device, which is used for testing the fatigue strength of a spring (9) to be tested, and comprises a clamp bottom plate (1), a lower positioning plate (3), an upper pressure plate (5) and spring positioning pins (4) for fixing the spring (9) to be tested. The spring (9) to be tested is sleeved on the spring positioning pins (4); and the spring positioning pins (4) are in clearance fit with the mounting holes on a lower positioning plate (3). When the technical scheme is adopted, the clamping is reliable, the spring to be tested can be changed conveniently, the device is suitable for fatigue tests of springs of different specifications, and can replace the conventional manual operation method, improve test efficiency and reduce production cost.

Description

Technical field [0001] The invention belongs to the technical field of the manufacturing process of mechanical parts, and relates to its testing instrument. More specifically, the invention relates to a spring fatigue test device. Background technique [0002] At present, components in the automobile industry, such as pumps and valves, are equipped with springs of different specifications; while the springs are under load during work, their load force and fatigue strength directly affect the components. , And even the quality of the product. [0003] In the current industry production, testing the fatigue resistance of springs is often manually operated by a manual press, and only one spring can be tested at a time, which is labor-intensive and low-efficiency. Summary of the invention [0004] The problem to be solved by the present invention is to provide a spring fatigue test device, the purpose of which is to improve the efficiency of spring fatigue strength test. [0005] In ord...
