Abstract
The utility model relates to the technical field of a testing device used for testing micro pump transmission accuracy, and particularly relates to a micro pump transmission mechanism testing device. The testing device detects transmission errors and the errors are displayed. The testing device comprises a coupler, an encoder and a counter. The coupler is connected with a stepping motor rotating shaft. The encoder is provided with an encoder rotating shaft which is connected with the coupler. The counter is electrically connected with the encoder. The counter is provided with a display module. When the stepping motor rotating shaft rotates at a certain speed, the encoder rotating shaft connected with the coupler rotates jointly under an effect of a linkage transmission torque of the coupler. Rotation angle displacement of the tested rotating shaft of a photovoltaic coded disc arranged in the internal part of the encoder is converted into a high-speed pulse signal, and counting is performed on the pulse signal via the counter.

Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of micro pump gear train proving installation that detects driving error and show.
Micro pump gear train proving installation of the present utility model, comprises shaft coupling, scrambler sum counter; Described shaft coupling and stepping motor rotating shaft link together, and are provided with scrambler rotating shaft on described scrambler, and described scrambler rotating shaft and shaft coupling link together, and described counter is electrically connected to scrambler, and is provided with display module on described counter;
When stepping motor rotating shaft rotates with certain speed, the effect of the interlock transmitting torque by shaft coupling is rotated coupled scrambler rotating shaft jointly, the photoelectric code disk of scrambler inside is converted into high-speed pulse signal by the displacement of tested rotating shaft rotation angle, and counts by counter pulse signals.
Micro pump gear train proving installation of the present utility model, described stepping motor rotating shaft and scrambler rotating shaft are all fixed by screw with shaft coupling.
Compared with prior art the beneficial effects of the utility model are: by above-mentioned setting, can draw by final counter stepper motor rotational displacement amount in the unit interval, compare with the theoretical numerical value of controlling motor operation, can draw the actual displacement angle of stepper motor and the departure of theoretical angular displacement, reach and quantize the object of micro pump gear train error and show by display module.
