Device and method for detecting assembly precision of hinge rod

Abstract

The invention provides a device for detecting the assembly precision of a hinge rod, and the device comprises an eccentric distance detection tool, a performance detection tool, a pin shaft A and a pin shaft B. The eccentric distance detection tool is used for testing the eccentric distance of the hinge rod in an unfolded state. The performance inspection tool is used for detecting the hole distance of the hinge rod in the unfolded state and the unfolding and folding performance of the hinge rod; the pin shaft A is used for fixing the hinge rod on the eccentric distance inspection tool or theperformance inspection tool and has the functions of fixing and parking; and the pin shaft B is used for combining the inner hinge rod and the outer hinge rod to form a product hinge rod. The invention provides an assembly precision detection method of a hinge rod. In the assembling and adjusting process, a special auxiliary tool is adopted for measuring the product assembly precision, the matching correctness of the hinge rod is detected in advance, rapid matching and precision measurement of the hinge rod are achieved, and the precision requirement that the hole distance between the two endsis 324 + / -0.05 mm and the eccentric distance is 5.97 mm and the unfolding and folding performance test can be guaranteed.

Description

technical field [0001] The invention relates to the field of aerospace assembly, in particular to a hinge rod precision detection device and a precision detection method thereof. Background technique [0002] The large solar wing adopts the deployment mechanism, which has a large folding ratio, takes up little space during the launch process, and can reach a length of 20m after deployment. In the process of space expansion, the solar wing needs to use the space expansion mechanism to realize the expansion and contraction of the battery array, and it is used as a structural element to support the force-bearing system. The unfolding mechanism is generally composed of multi-section unfolding and retracting units, and each unit has the same composition. The hinge rod is one of the key components in the unfolding and retracting unit. Its accuracy is the key to the fundamental frequency of the unfolding mechanism itself, which directly determines the reliability of the unfolding a...
