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 a test instrument thereof. More specifically, the invention relates to a spring fatigue test device. Background technique [0002] At present, in the parts of the automobile and other industries, such as some pumps and valves, springs of different specifications are installed; and the springs are under load during work, and its load force and fatigue resistance directly affect the components. , and even product quality. [0003] In the current industrial production, the detection of spring fatigue resistance is often manually operated by a manual press, and only one spring can be tested at a time, which is labor-intensive and low in efficiency. Contents 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 the spring fatigue...
