A method for machining and clamping a carbon fiber composite material plane frame suspended state for satellites

Abstract

The invention discloses a satellite carbon fiber composite plane frame suspension state machining clamping method. The method comprises following steps: supporting points of a certain number can be fixed to the to-be-machined face of a frame, a carbon fiber composite plane frame is suspended, and the gravity direction and the frame mounting plane are kept parallel to a certain degree; the supporting points are subject to measuring, trimming or adjusting, and the surfaces of the supporting points can reach certain coplanarity under the suspension state; the supporting point plane serves as the clamping standard, and the frame is clamped on a machine tool in a flat manner. Through the clamping method, the mounting face of the plane frame is machined, the variable, caused by gravity, of the product can be controlled within the index allowable range, the influence of the curing stress of the composite plane frame on the plane is reduced, and the planeness of the machined product mounting face meets the precision requirement under the space weightlessness environment.

Description

technical field [0001] The invention belongs to the field of composite materials and machining, and in particular relates to a method for machining and clamping a plane frame of a carbon fiber composite material for a satellite in a suspended state. Background technique [0002] The planar frame is a commonly used antenna module carrier for satellites. Generally, carbon fiber composite material parts are used to complete the assembly by bonding. The metal sheet bonded to the composite material is integrally machined to ensure the accuracy of the mounting surface. When the satellite is launched, the antenna frame is It is folded together and unfolded after the satellite is in orbit. Due to the large planar area and small thickness of the planar frame, the bending stiffness is poor, and its planarity is difficult to maintain in an environment affected by gravity and in a weightless space environment. [0003] In order to solve the influence of gravity on the flatness of the p...
