Technical Field

[0001] The utility model relates to the technical field of diaphragm fatigue testing, in particular to a diaphragm fatigue testing platform. Background Art

[0002] The diaphragm is a key component in the water pump, and the water pump is a very important component in the field of water source automatic control. The diaphragm inside it must be fatigue tested to test its service life.

[0003] The existing diaphragm fatigue test method usually involves turning water pressure on and off to cause the diaphragm to deform and recover. After the test, the diaphragm is checked to see if it is deformed too much, cracked, or penetrated. If no abnormalities are found after this process is repeated tens of thousands of times, the test is considered to be qualified. However, the platform's diaphragm testing requires manual participation in repeated water supply and discharge, and also requires a drainage process. The labor intensity of the workers is high, the test efficiency is extremely low, the accuracy of the test results is reduced, and it is difficult to accurately evaluate the diaphragm performance.

[0028] Meanwhile, in the following description, many specific details are set forth for the purpose of explanation to provide a thorough understanding of the embodiments of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without the specific details or the specific manner described herein.

[0029] See also Figure 1-3The utility model provides a diaphragm fatigue test platform, including: a base 1, a support column 2, a bracket plate 3, a pressure plate 4, a diaphragm 5, and a reciprocating shaking assembly 6. The support column 2 is arranged on the base 1; the bracket plate 3 is connected to the support column 2; the pressure plate 4 is detachably connected to the bracket plate 3 through a locking member; the diaphragm 5 is located between the pressure plate 4 and the bracket plate 3; the reciprocating shaking assembly 6 is installed on one side of the support column 2 and is located below the diaphragm 5; wherein the reciprocating shaking assembly 6 includes a motor 61, a turntable 62, a camshaft 63, a connecting rod 64, The hinge seat 65, the shaking plate 66, the slider 67, the slide rail 68, the fixed plate 69, and the turntable 62 are installed on the motor 61. One side of the connecting rod 64 is rotatably connected to the eccentric point of the turntable 62 through the camshaft 63, and the other side is also rotatably connected to the hinge seat 65 through the camshaft 63. The hinge seat 65 is installed on the lower side of the shaking plate 66, and the slider 67 is installed on the rear side of the shaking plate 66. The slider 67 is set on the slide rail 68, and the slide rail 68 is installed on the fixed plate 69. The fixed plate 69 is connected to the bracket plate 3, and the shaking plate 66 is located below the diaphragm 5.

[0030] When in use, the diaphragm 5 to be fatigue tested is placed on the bracket plate 3, and then the pressure plate 4 is locked to the bracket plate 3, so that the diaphragm 5 is fixed between the bracket plate 3 and the pressure plate 4 and is also located above the reciprocating shaking assembly 6, then the motor 61 is started, and the turntable 62 rotates mechanically. During rotation, the connecting rod 64 is pulled up and down by the action of the camshaft 63, and the shaking plate 66 is rotatably connected to the camshaft 63 through the hinge seat 65, so that the shaking plate 66 will move up and down along the slide rail 68 with the slider 67, and the diaphragm 5 will be knocked and shaken back and forth when moving, thereby performing fatigue testing on the diaphragm 5.

[0031] According to some embodiments of the present application, the locking member may optionally be a screw structure, which has the effect of making the locking method simple and easy to operate.

[0032] According to some embodiments of the present application, the shaking plate 66 is optionally made of aluminum, which is environmentally friendly, impact-resistant, and more durable.

[0033] According to some embodiments of the present application, optionally, the motor 61 is mounted on the base 1 , which has the function of mounting the reciprocating shaking assembly 6 on the base 1 .

[0034] According to some embodiments of the present application, a stand 7 is optionally mounted on the base 1. The top of the stand 7 is positioned above the diaphragm 5. A camera 8 is connected to the upper side of the side column of the stand 7. Light sources 9 are mounted on all four sides of the top of the stand 7. The camera 8 is externally connected to a camera image receiving device. The light sources 9 are positioned above the diaphragm 5, and the camera 8 is positioned above the diaphragm 5. Due to various defects on the surface of the diaphragm 5, the optical properties of the diaphragm 5 will inevitably differ from those of the diaphragm 5 itself. That is, after the light from the light source 9 is incident on the surface of the diaphragm 5, the various defects on the diaphragm 5 will exhibit different reflection, refraction, and other characteristics from the surrounding area. When the uniform light from the light source 9 is incident on the surface of the diaphragm 5, if the surface is free of defects, the direction of the light will not change, and the detected light will also be uniform. When the surface contains defects, the emitted light will change, and the image detected by the camera image receiving device will also change accordingly. Due to the presence of defects, stress concentration and deformation will occur around the defects, which are more easily observed in the image. If a light-transmitting defect (such as a crack) is encountered, the light will be refracted at the defect location, and the light intensity will be greater than the surrounding light. Therefore, the light detected by the camera 8 will also be enhanced accordingly. The camera image receiving device analyzes the intensity changes and image features of the image signal collected by the camera 8, and can obtain the corresponding defect information, so that the quality of the tested diaphragm 5 can be known.

[0035] According to some embodiments of the present application, optionally, a plurality of anti-slip feet 10 are provided at the lower end of the base 1, which have the effect of making the base 1 more stable.
