Abstract

The invention provides a flexible pressing device for low-rigidity components and an assembling and pressing method of the flexible pressing device. The flexible pressing device is characterized in that a pressing assembly comprises a first force application part and a second force application part sequentially arranged in the force application direction; the first force application part comprises an upper pressing block and pressing springs pressed downwards by the upper pressing block; the second force application part comprises a lower pressing block propped against the pressing springs and jacking springs pressed downwards by the lower pressing block; a pressing part for pressing the low-rigidity components is connected to the lower pressing block. According to the invention, whether the controlled pressing force value is within a required range or not can be judged through visually observing the displacement values of the upper pressing block and the lower pressing block and the position difference value of the upper pressing block and the lower pressing block, so that the stress state requirements during the assembly can be met; besides, the flexible pressing device can buffer the impact force to the maximum extent during pressing through the elastic deformation of the jacking spring and the pressing spring, and the damage to pressed components under a certain degree of overload force is avoided.

Description

technical field [0001] The invention relates to a flexible pressing device for weakly rigid parts, in particular to a flexible pressing device for aircraft weakly rigid panel parts based on a limited assembly pressing force range and a method for assembling and pressing weakly rigid parts. Background technique [0002] The control of the pressing force of aircraft weak rigid parts in the assembly process of docking and connection is a common difficulty in the current aircraft assembly line. The value of the pressing force will directly cause the displacement deviation of weak rigid parts to increase or damage the parts, so It is a factor that can not be ignored to affect the quality of assembly. [0003] At present, more researches are mainly focused on the deformation control in the manufacturing process of weakly rigid parts of the aircraft, and the structural form mostly adopts the method of sensor and screw. For example, the patent application CN103481094A provides a fl...
