Description

Technical Field

[0001] The utility model relates to the technical field of fatigue testing machines, in particular to a low-noise and high-frequency fatigue testing machine. Background Art

[0002] A high-frequency fatigue testing machine is a versatile, professional device for testing the mechanical properties of materials. It achieves significant results through the principle of electromagnetic resonance. During electromagnetic resonance, the high frequency and high load cause the entire machine to vibrate, generating noise levels of 110dB or higher. Due to limited space in many testing laboratories, operators cannot remain in close proximity to the equipment for extended periods, or even in the same room. Traditional high-frequency fatigue testing machines reduce noise levels by adding semi-open (full-length) panels and soundproofing to the upper half of the machine. Utility Model Content

[0003] The purpose of the utility model is to provide a low-noise high-frequency fatigue testing machine to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a low-noise, high-frequency fatigue testing machine, comprising a fatigue testing machine body, a buffer spring fixedly provided on the bottom surface of the fatigue testing machine body, one end of the buffer spring away from the fatigue testing machine body fixedly connected to the widened bottom plate, a vibration source soundproof cover provided on the fatigue testing machine body, a fully enclosed enclosure provided on the outside of the fatigue testing machine body, located around the widened bottom plate, and a cooling fan provided on the top of the fully enclosed enclosure.

[0005] Preferably, the fully enclosed enclosure is filled with sound insulation cotton, and a glass door is provided on one side of the fully enclosed enclosure.

[0006] Preferably, the glass door is a double door, and the glass door is rotatably connected to a fully enclosed enclosure.

[0007] Preferably, the bottom surface of the widened bottom plate is provided with a rubber layer.

[0008] Compared with the existing technology, the beneficial effect of the present invention is that the fatigue testing machine body is enclosed in a space by a fully enclosed enclosure, and the noise generated is doubly reduced by the source sound insulation cover and the fully enclosed enclosure, which effectively reduces the spread of noise and facilitates promotion.

[0011] In the figure: 1. Fatigue testing machine body; 2. Buffer spring; 3. Widened bottom plate; 4. Vibration source sound insulation cover; 5. Fully enclosed enclosure; 6. Cooling fan. DETAILED DESCRIPTION

[0012] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0013] Please refer to 1-2. An embodiment of the present invention is: a low-noise and high-frequency fatigue testing machine, comprising a fatigue testing machine body 1, a buffer spring 2 is fixedly provided on the bottom surface of the fatigue testing machine body 1, and the end of the buffer spring 2 away from the fatigue testing machine body 1 is fixedly connected to the widened bottom plate 3, and a vibration source sound insulation cover 4 is provided on the fatigue testing machine body 1. On the outside of the fatigue testing machine body 1, a fully enclosed enclosure 5 is provided around the widened bottom plate 3, and a cooling fan 6 is provided on the top of the fully enclosed enclosure 5. The fatigue testing machine body 1 is closed and soundproofed by the fully enclosed enclosure 5 and the widened bottom plate 3, thereby reducing the spread of noise in all directions, effectively reducing the spread of noise to the external environment, and protecting users from noise damage. In addition, the internal vibration source sound insulation cover 4 performs preliminary noise reduction on the structure on the fatigue testing machine body 1 that generates noise, and attenuates the noise twice to further reduce the noise.

[0014] The fully enclosed enclosure 5 is filled with sound insulation cotton, and a glass door is opened on one side of the fully enclosed enclosure 5; the glass door is a double door, and the glass door is rotatably connected to the fully enclosed enclosure 5; the bottom surface of the widened bottom plate 3 is provided with a rubber layer, and the glass door can effectively observe the interior, and can be opened, and it is convenient to place and put away the inspected items without affecting the inspection of the items. The bottom surface of the widened bottom plate 3 is provided with a rubber layer, which can also effectively buffer vibrations and play a buffering role when the friction with the bottom surface is increased.

[0015] Working principle: When in use, the object to be tested is placed at the detection position on the fatigue testing machine body 1 through the glass door, and then the fatigue testing machine body 1 is started to start the test. During the test, the glass door is closed, and the noise generated by the fatigue testing machine body 1 will first be reduced for the first time through the source sound insulation cover 4. After it spreads to the surroundings of the fatigue testing machine body 1, it will be blocked by the fully enclosed enclosure 5 when it spreads to the outside world. The noise is then reduced for the second time by the fully enclosed enclosure 5, effectively reducing the spread of noise.
