Description

Technical Field

[0001] The invention relates to the technical field of disc spring testing, and in particular to an elastic fatigue attenuation testing device and method based on disc spring production. Background Art

[0002] Disc springs, also known as Belleville washers or disc springs, are springs with a conical cross-section, usually used in applications that require high load-bearing capacity and large deformation. They consist of single or multiple disc-shaped metal sheets stacked together, which are compressed and deformed when subjected to pressure, thereby generating elastic force. The design of disc springs enables them to provide very high elastic force and energy absorption capacity in a limited space. They have the characteristics of high load bearing, compactness, nonlinearity, combined use and long life. In certain specific use environments, they also need to be painted to avoid corrosion.

[0003] Publication number CN203231890U discloses a device for testing spring elasticity, including a base, on which a pressure plate is arranged, the pressure plate is divided into an upper pressure plate and a lower pressure plate, the upper pressure plate is arranged above the lower pressure plate, the lower pressure plate is fixed to the base, the upper pressure plate and the lower pressure plate are symmetrical along a horizontal plane, and several pressure gauges are arranged on the upper pressure plate, and the probes of the pressure gauges point to the lower pressure plate.

[0004] Although the above application and the prior art can accurately test the elasticity of the spring through multiple pressure gauges, the results are accurate, so that the spring can be applied to appropriate fields. However, when the device detects the disc spring, due to the different sizes of the disc springs, it is impossible to adjust the support according to the sizes of different disc springs during the detection, which will cause errors in the test results. Moreover, since the disc spring is usually composed of multiple disc-shaped metal sheets stacked together, only the disc spring as a whole can be detected during the detection, and it is impossible to detect a single or multiple of them, which leads to incomplete test results. Moreover, when the disc spring is detected as a whole, the anti-corrosion material on the surface of the disc spring will fall off. If it is not handled in time, when detecting disc springs of other sizes, the disc springs will not be placed at the same level, which will cause errors in the test results. Therefore, we propose an elastic fatigue attenuation test device and method based on disc spring production. Summary of the invention

Moreover, since disc springs are usually composed of a plurality of disc-shaped metal sheets stacked together, only the disc spring as a whole can be tested during testing, and it is impossible to test a single or multiple disc springs, which results in incomplete test results. Moreover, when testing the disc spring as a whole, the anti-corrosion material on the surface of the disc spring will fall off.

[0056] Step 1: Place the disc spring to be tested on the surface of the fixed cylinder 16, start the support assembly 3, and support the inner wall of the disc spring by the support assembly 3;

[0057] Step 2: When the disc spring needs to be tested as a whole, the pressurizing component 2 is started, the disc spring is squeezed by the pressurizing component 2, and then the pressurizing component 2 is restored to the initial state, and the elastic fatigue attenuation of the disc spring is tested by the testing component 13;

[0058] Step 3, when the pressure component 2 detects the disc spring as a whole, the anti-corrosion material on the surface of the disc spring will be detached, and the pressure component 2 drives the cleaning component 6 to start when in operation, so that the cleaning component 6 cleans the anti-corrosion material on the surface of the disc spring to prevent the fallen anti-corrosion material from affecting the detection of elastic fatigue attenuation of the disc spring during subsequent tests;

It is necessary to detect the disc spring during the detection. When cleaning the anti-corrosion material fallen on the surface of the disc spring, the first motor 21 drives the pressure plate 221 to move through the screw 22, and at the same time drives the driving sprocket 61 to rotate. The driving sprocket 61 drives the driven sprocket 621 to rotate through the chain 611, so that the driven sprocket 621 drives a number of fan blades 622 to rotate through the rotating column 62.
