Adjustment device and adjustment method for fine rib center coincidence of gyro flexible joint

Abstract

The invention provides a gyroscope flexible joint thin rib center coincidence adjustment device and an adjustment method thereof. A flexible joint in a workpiece is fixed on a rotary table of a device through a lifting screw of the device. the rotary table is rotated to calibrate a center of a thin rib of an inner flexible joint to coincide with a central surface of a reference hexahedron, then the rotary table is locked by utilization of a rotary table fastening screw, an outer flexible joint sleeves the inner flexible joint, the center of the thin rib of the outer flexible joint is calibrated to coincide with the central surface of the reference hexahedron, and then the outer flexible joint is fixed by utilization of a fastening screw. In the method, the device can calibrate the centers of the thin ribs of the inner flexible joint and the outer flexible joint accurately, reading is carried out through a tool microscope, quantification of rib aligning errors can be achieved, and thin rib stressing skewing and angle positioning error problems can be solved which are possibly caused by employing of a sliding block contact component plane rib aligning method at present.

Description

Adjustment device and adjustment method for fine rib center coincidence of gyro flexible joint technical field The invention relates to an assembly and adjustment equipment and an adjustment technology, in particular to a center overlapping device and an adjustment method for thin ribs of inner and outer flexible joints of a gyroscope. Background technique After the inner and outer flexible joints of the dynamic adjustment gyroscope are processed separately, they must be combined, that is, the outer flexible joints are coaxially inserted into the position specified by the inner flexible joints, and the center alignment error of the fine ribs is adjusted to be less than ±3', so the combined A key issue in the assembly and adjustment process is to ensure that the centers of the thin bars of the inner and outer flexible joints are strictly aligned (the centers of the two thin bars coincide). This alignment error will directly affect the performance indicators of the joints. H...

Problems solved by technology

In this method, in order to ensure that the pin can be accurately inserted into the thin rib hole of the outer flexible joint, the outer diameter of the pin is affected by the machining accuracy of the tooling, the machining accuracy of the thin rib hole of the outer flexible joint, and the matching accuracy of the inner and outer flexible joints. The outer diameter of the pin must be made Small, the disadvantage is that it directly affects the positioning accuracy, and the method of adjusting the end face of the inner flexible joint is used to indirectly locate the position of the thin rib, which also introduces the factor of part processing error
