Abstract
The invention belongs to the testing method and particularly relates to an electric actuator clearance testing method. The method comprises steps: step 1, testing equipment is mounted; step 2, a weight is hung on a hook provided with a dial indicator so as to apply a vertical and downward torque to the electric actuator; step 3, zero is adjusted, and the point of the dial indicator in the condition of weight hanging is adjusted to be zero; step 4, the weight is taken away from the hook and hung on a hook in the opposite symmetrical position and the reading of the dial indicator is recorded; and step 5, the electric actuator clearance is calculated. The electric actuator clearance testing method has the beneficial effects that the electric actuator clearance which needs to be measured directly is changed into distance data measured indirectly, the electric actuator clearance is then calculated according to the distance data, the measurement process is simple, and the measurement accuracy is high.
Description
Technical field
The invention belongs to method of testing, be specifically related to a kind of electric steering engine clearance test method.
Background technology
Electric steering engine is the important servo control mechanism of the one of missile weapon system, is the topworks of rudder system, drives control surface deflection, to realize the control to missile flight attitude.The transmission accuracy of electric steering engine directly affects the control accuracy of rudder system, and then the control of impact to missile flight attitude.The gap of electric steering engine inside is the principal element that affects steering wheel transmission accuracy, therefore tackles the gap of steering wheel inside and effectively tests, to it is adjusted and is controlled.In prior art, there is no the method in Measurement accuracy electric steering engine gap.
Summary of the invention
The object of the invention is the defect that cannot accurately measure electric steering engine gap for prior art, a kind of electric steering engine clearance test method is provided.
The present invention is achieved in that a kind of electric steering engine clearance test method, comprises the steps:
Step 1: installation testing equipment
Electric steering engine is arranged on steering wheel support, then depression bar assembly is fixed on by card extender mounting screw on the output shaft of electric steering engine,
Step 2: hang counterweight
Under the hook that is provided with dial gauge, hang counterweight, electric steering engine is applied to moment straight down,
Step 3: zeroing
In the situation that articulating counterweight, the pointer of dial gauge is adjusted into zero-bit,
Step 4: counterweight transposition
Counterweight is taken off from hook, and is suspended on the hook of reverse symmetry position, then write down dial gauge reading,
Step 5: calculate
With following formula calculating electric steering engine gap
A kind of electric steering engine clearance test method as above, wherein, in step 1, described depression bar assembly comprises discoidal output shaft card extender, on output shaft card extender, be fixedly connected with depression bar with depression bar mounting screw, two ends at depression bar arrange hook, and a hook top arranges dial gauge therein, and gauge outfit contact pilotage is vertically against on the position of indicating in advance.
The invention has the beneficial effects as follows: the electric steering engine gap that must directly measure is converted to the range data of indirect measurement, then extrapolates electric steering engine gap according to range data, measuring process is simple, measure accuracy rate high.
