Problems solved by technology

[0003] However, in the current prior art, after the production of the fan is completed, the vibration frequency of the fan needs to be detected. After the fan is assembled in the computer, if the vibration frequency of the fan exceeds the standard, it will emit noise, which will affect the user experience and thus affect the product. The current fan vibration test is carried out by holding a fixed sensor in contact with the fan, which has a certain degree of human influence, resulting in data errors

Abstract

The invention discloses a vibration testing device for a fan. The vibration testing device comprises a base testing box, a placing box, a plurality of groups of first buffer mechanisms, a plurality ofgroups of second buffer mechanisms, a vibration sensor and a central processing unit, wherein the placing box is fixedly arranged on the surface of the top end of the testing box, the testing box isarranged on the inner side of the base, and the vibration sensor is fixedly arranged on the surface of the bottom end of the testing box through bolts. According to the vibration testing device, the first buffer mechanisms are arranged, so that the left-right shaking of the testing box can be realized; springs have very good buffering performance, so that the vibration frequency generated by the testing box when the fan works can be guaranteed, and the testing accuracy cannot be reduced; and a clamping mechanism is arranged, so that the defects of traditional bolt fixing are overcome, the clamping stability effect can be improved, the time and the energy required by fan installation can be reduced, and the testing efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of fan production, in particular to a vibration test device for a fan. Background technique [0002] Fan refers to a device used to generate wind to keep cool in hot weather. Electric fan is a device driven by electricity to generate air flow. The fan inside is energized and then rotated into natural wind to achieve the effect of cooling. It is used for heat dissipation and is provided for radiators and chassis. The size of general cooling fans on the market ranges from 2.5cm to 30cm in diameter, and 6mm to 76mm in thickness. According to different operating requirements, rare AC (AC) fans can be used. , take power from household sockets) and common D power supply (DC, take power from computer fire cow or motherboard), most of them use two-phase motors (two sets of copper coils, a total of four units), which is conducive to low speed To save production costs, computer fans are divided into chassis fans and ...
