Description

Mute tester

Technical field

The utility model relates to a kind of electric current of test computer fan and Mute tester of rotating speed, waveform and different sound of being used for.

Background technology

Existing Mute tester, four contents of general test, the one, electric current and rotating speed, the 2nd, waveform, the 3rd, different sound test, the 4th, motor vibration test, electric current and measurement of rotating speed have two kinds at present: 1. the control box rotating speed shows with gauge outfit; 2. directly demonstrate rotating speed on computers with the fan test system testing; For waveform is waveform with the oscillograph fan; And the test of different sound and vibrations, be that personnel selection takes product mostly, different sound and vibration test overturn in the quiet chamber of this kind equipment, the result of its test judges the quality of product by the long experience of people, because there is mismatch in stirring of staff, therefore, same computer fan is by different people, the result who measures is different, and its accuracy is relatively poor.

Summary of the invention

The technical matters that the utility model solves is to overcome above-mentioned shortcoming, provides a kind of and can improve test result accuracy, intuitive display, and finish the Mute tester of digitized processing entirely.

The technical solution of the utility model is: design a kind of Mute tester, comprise soundproof box main body, data processing equipment and display, data processing equipment input termination shock sensor, different sound sensor; Its output terminal and display join; Described soundproof box main body comprises the computer fan rotating mechanism, and the computer fan rotating mechanism can stretch out or indentation in the opening of soundproof box main body one side.

Described computer fan rotating mechanism comprises base plate, in base plate one side a side plate vertical with base plate is arranged, and is furnished with power source on base plate, gear train and rotary body, power source and gear train join, and gear train and rotary body join, and the fan geometrical clamp is arranged on rotary body.

Also comprise the translation cylinder that controlling computer fan rotating mechanism is flexible, the translation cylinder joins by cylinder guide rod and computer fan rotating mechanism.

Described power source is revolving cylinder or servomotor.

Described gear train is driving belt or gear drive.

Two gauge tap are arranged on the outer wall of described soundproof box main body.

Below the soundproof box main body, operator's console is arranged.

In soundproof box main body one side, data processing equipment is arranged on the operator's console.

The utility model is owing to adopted data processing equipment and display, data processing equipment is collected the electric current and the information such as rotating speed, waveform, different sound and vibrations of computer fan, passing to display after treatment shows, do the demonstration of waveform with computing machine, can be more intuitively to the judgement of electric current and rotating speed; With computing machine judge the wide-to-narrow ratio of fan waveform and height than, it is more accurate to show than traditional oscillograph; In addition, in the soundproof box main body, also be provided with the computer fan rotating mechanism, the computer fan rotating mechanism can stretch out or indentation in the opening of soundproof box main body one side, after the indentation, computer fan rotating mechanism and soundproof box main body constitute the structure of a sealed whole body, like this, overturn with machine and to replace artificial upset to carry out the multiaspect test, improved different sound measuring accuracy widely, and, directly made the judgement of " qualified OK " or " defective NG " by data processing equipment according to the size of different sound.
