Abstract

The invention relates to a testing machine, in particular to a spring fatigue testing machine. The purpose of the present invention is to provide a spring fatigue testing machine which is easy to use and can dissipate the heat during spring testing without affecting the testing. A spring fatigue testing machine includes a base, a bracket and the like; the base is provided with a bracket. The invention can drive the hollow cylinder to move up and down continuously through the electro-hydraulic push rod, so that it can be pulled up by cooperating with the special-shaped guide clamp, so that the test spring hanging on it can be pulled up, and the hollow cylinder can be connected with the chute ring The top is in contact, so that the first swing clamping rod is no longer in contact with the special-shaped guide clamping plate, so that the special-shaped guide clamping plate can be released, so that the test spring can be moved downward, and the fatigue test can be carried out to the spring repeatedly.

Description

technical field [0001] The invention relates to a testing machine, in particular to a spring fatigue testing machine. Background technique [0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials are deformed under the action of external force, and return to their original shape after the external force is removed. [0003] At present, springs are widely used in various fields, but the spring itself has elastic fatigue. In some precision instruments, the requirements for the spring are very high. Before the spring appears elastic fatigue, the spring must be replaced to ensure the normal use of the instrument. The elastic fatigue characteristics of the spring have become the main parameters for the selection of springs, so the spring elastic fatigue test device has become a necessary device for spring manufacturers and application manufacturers. [0004] The currently used spring fatigue testing machine is relatively complicated to...
