Abstract

The invention discloses a processing method of a nonmetal special-shaped rudder sheet and a clamp for processing. The processing method comprises the following steps: 1) designing a nonmetal rudder sheet flat blank according to a product maximum profile dimension; 2) vertically clamping the nonmetal rudder sheet flat blank, symmetrically grinding the two reference surfaces of the nonmetal rudder sheet flat blank; 3) performing rough milling of the profile of the nonmetal rudder sheet flat blank, processing a process chuck for subsequent clamping at a position of a rudderpost; 4) vertically clamping the process chuck, aligning the central planes of the two reference surfaces, performing semi-finish milling of the reference surfaces of the nonmetal rudder sheet flat blank, then performing finish milling one surface to obtain the designed dimension so as to form the rudder sheet; 5) vertically clamping the rudder sheet, performing semi-finish milling of the process chuck to obtain a rudderpost shape; 6) performing finish milling of the rudderpost to obtain the designed dimension so as to finish the processing of the nonmetal special-shaped rudder sheet. With the processing method of the nonmetal special-shaped rudder sheet and the clamp for processing, the processing precision and the form and location tolerance of the nonmetal special-shaped rudder sheet can be effectively ensured.

Description

technical field [0001] The invention belongs to the technical field of non-metallic rudder blades for motorized warheads in missile weapon systems, and specifically refers to a processing method for non-metallic special-shaped rudder blades and a fixture for processing. Background technique [0002] The mobile warhead is a missile weapon system warhead that changes the flight trajectory according to a predetermined program at the end of the trajectory. When the maneuverable warhead is re-entry, its control system uses the aerodynamic force generated by the deflection of the air rudder as the control force to effectively control the missile in the atmosphere to ensure a good attitude flight. The air rudder is composed of rudder blades, adapter rings and their connectors, and the rudder blades and adapter rings are connected by threads. In view of the long maneuvering flight time of the weapon system, the ablation of the rudder and wings, and the high temperature structural s...
