Spring salt mist fatigue test device

Abstract

The invention provides a spring salt mist fatigue test device. The spring salt mist fatigue test device comprises a spring fatigue testing machine, the spring fatigue testing machine comprises a testing mechanism, the testing mechanism further comprises a casing pipe and a salt mist spray device, one end of the casing pipe is sleeved on a first spring seat of the testing mechanism, the other end of the casing pipe is sleeved on a second spring seat of the testing mechanism, the salt mist spray device is arranged in the casing pipe, the salt mist spray device comprises a water spray hole and an air jet hole, the water spray hole is connected with a brine tank through a pipeline, the air jet hole is connected with an air source device through the pipeline, the fatigue test for a spring is completed by the testing mechanism, the casing pipe arranged on the testing mechanism is utilized to form enclosed space between the first spring seat and the second spring seat, the salt mist spray device disposed in the casing pipe is utilized for spraying salt mist on the spring, the salt mist spraying is performed while the spring is subjected to the fatigue test, the spring fatigue test and spring salt mist test can be simultaneously performed, and thereby the spring fatigue corrosion test can be completed.

Description

technical field [0001] The invention relates to a spring test device, in particular to a spring salt spray fatigue test device. Background technique [0002] As a mechanical part that uses elasticity to work, springs have been widely used in mechanical equipment and instruments. When people use the spring, they mainly use its reset function. However, after the spring has been used for a period of time, its reset function will gradually weaken, which will eventually lead to the failure of the spring; therefore, the reset ability of the spring is a key factor that directly affects the service life of the spring. . For this reason, people often use the spring fatigue testing machine to test the reset function of the spring, so as to test the service life of the spring and ensure the normal use of the spring. [0003] Currently, if figure 1 As shown, a common spring fatigue testing machine includes a test mechanism 1, and the test mechanism 1 is composed of a base plate 11, a...

Problems solved by technology

[0004] But as we all know, the springs in some mechanical devices are usually exposed to the air, and the working environment contains corrosive components and factors such as oxygen, humidity, temperature changes, and pollutants, which will cause certain corrosion to the springs, and then affect the The strength of the spring's own structure will affect the service life of the spring. For this reason, people often use salt spray testing machines to conduct salt spray tests on springs.

[0005] At present, the spring fatigue test and the spring salt spray test are carried out separately, and it is impossible to carry out salt spray spray during the spring fatigue test, so it is difficult to test the service life of the spring in the working environment
