The accuracy measurement for locking force, which directly affects the launching disturbance and missile＇s motion attitude of rock- et launcher, would be significant for improving the lannch precision. Aiming at the problem of large error, limited detecting range, and poor efficiency caused by traditional detecting devices, an automatic detecting device for locking force was introduced here, based on the study of a series aspects, such as the detection and control principle, power transmission way, working load, and the finite element simulation on crit- ical components. In this device, the power transmission was realized with single-rotating reciprocating lead screw, and the locking force can be detected in real time by ＂S＂ shape pressure sensors controlled by drive circuit, which took chip TMS320F2812 as the core processor. So, a wide range of continuous automatic detecting and accurate output were realized. This device was used to detect the locking force of a new launch equipment. The results indicate that it can effectively improve the detecting accuracy of locking force, expand the detecting scope, and improve the detecting efficiency.
