Further, said support column has four, and first crossbeam that is connected support column middle part and top also has four respectively, and second crossbeam that is connected on the framework between support column middle part and the top also has four.
Further, the bumping post and the anti-principal vertical line that fixed stably voltage source are installed on the said base plate roll mobile line and roll pickup groove.
Further, more firm in order to make framework, said support column is connected through steel square with first crossbeam.
Further, can move stand more convenient, quickly when testing, be connected with roller respectively through bearing in the bottom of four support columns in order to let.
Further, in order to let the more firm of microphone clamping, said microphone fixture is connected on second crossbeam through screw, and microphone fixture is made up of microphone anchor ear and bolt cooperation.
Its course of work is following: at first will be tacked with bungee by measured motor, and make the center that is in framework upper by measured motor; Be separately fixed at microphone on second crossbeam of framework through microphone fixture again; Again line is rolled line in the pickup groove and roll and be connected on the socket, be connected on line and roll, will be connected on the stabilized voltage supply through power lead, with the voltage table in the voltage table stationary installation and be connected in the two ends at tested motor interface place by measured motor with being fixed on stabilized voltage supply in the bumping post; The voltage and current of adjustment stabilized voltage supply, the magnitude of voltage that on voltage table, shows is that setting gets final product, and treats at last to be tested by after measured motor preheating a few minutes.
The utility model is fixed on microphone on second crossbeam through microphone fixture, and microphone fixture does not move, and has guaranteed the consistance of each test data; To be tacked fixingly by measured motor through bungee, and place the center of framework upper, the vibration that when tested machine operation, produces seldom to be delivered on the test framework then, thereby guaranteed the accuracy and the validity of test figure; Stabilized voltage supply, voltage table, line roll all has stationary installation, has guaranteed clean and tidy, the standard of test; Adopt steel square to connect the support column and first crossbeam, guaranteed the fastness of framework; Bottom at support column connects roller, and it is convenient, fast to move stand when making test.

Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Like Fig. 1, Fig. 2, Fig. 3, Fig. 4, micro-machine noise testing stand shown in Figure 5, comprise by four support columns 2, be connected four first crossbeams 3 at support column 2 middle parts and be connected the square framework that four first crossbeams 3 on support column top are formed through steel square 12; On support column 2 and eight corners that first crossbeam 3 forms, be connected a bungee 6 respectively, bungee 6 connects by measured motor 5, will be hung in the framework upper center by measured motor 5; On one first crossbeam 3 at support column 2 middle parts, be welded with voltage table stationary installation 8; On the framework between four support column 2 middle parts and the top, be connected with four second crossbeams 4; The plane parallel that the plane of four second crossbeam 4 formation and four first crossbeams at support column 2 middle parts 3 form; In the framework end face, be connected with another root second crossbeam 4 between two first parallel crossbeams 3, on five second crossbeams 4, install one respectively by microphone anchor ear 71 microphone fixture 7 that 72 cooperations constitute with bolt through screw; Below framework, be provided with base plate 10, base plate 10 is welded on the bottom of support column, and the bumping post 11 that fixed stably voltage source is installed on base plate 10 rolls mobile line with anti-principal vertical line and rolls pickup groove 9; Bottom at four support columns 2 is connected with a roller 1 respectively through bearing.
