It is qualitative poor.Or drive ball-screw to realize that the displacement inputs with stepper motor, the control section of the stepper motor being related to compared with
For complexity, and to realize the small displacement, ball-screw cost is too high.
Summary of the invention
In order to solve the above-mentioned technical problem, the invention proposes a kind of test fixtures of rudder servo controller.
The technical problems to be solved by the invention are realized using following technical scheme:
A kind of test fixture of rudder servo controller, including rack, be arranged on rack be used for measurement direction rudder
The test device of servo controller on the rack and is located at the side of test device to be equipped with is rudder SERVO CONTROL to be tested
Device provide displacement power power output device, the power output device include coaxially connected direct current generator and camshaft,
With the cam axial end moment support close with realize ± 1mm move back and forth piston rod, setting piston rod end be used for and test
The product connector of product connection.
Further, the piston rod is slidably matched its promising fixation sliding block for mentioning linear steering.
Further, the idler wheel and cam axial end that the piston rod is connected by end thread, which support, to be closed.
Further, it is wound on the piston rod for eliminating gap so that idler wheel and cam axial end moment support conjunction
Spring.
Further, the piston rod end is connect by idler wheel connector with idler wheel.
Further, the piston rod end is equipped with for adjusting the adjusting nut for being threadedly coupled length.
Further, the piston rod is threadedly connect with product connector.
The beneficial effects of the present invention are:
By direct current generator as inputting, piston rod connects the present invention as output and with servo controller input connecting rod
It connects, by cam drive between motor and piston rod, so that piston rod drives the reciprocating motion of input connecting rod completion ± 1mm.Directly
The rotary speed property of galvanic electricity machine is preferable, can guarantee the stationarity of speed, and cam drive can guarantee the displacement accuracy of ± 1mm well,
And reduce manufacturing cost.
