Description
Technical field
The invention belongs to the nonmetal rudder chip technology of motor driven bullet field in missile weapon system, specifically refer to a kind of processing method and fixture for processing of nonmetal special-shaped rudder sheet.
Background technology
Motor driven bullet is by the missile weapon system bullet of preset program change of flight trajectory at terminal phase.Motor driven bullet reenters when flight, its control system be the air force that produced by airvane deflection as control, effectively control guided missile and ensure good attitude flight in endoatmosphere.Airvane is made up of rudder sheet, adapter ring and connector thereof, and rudder sheet adopts and is threaded with adapter ring.Long for the armament systems maneuvering flight time, the ablation to rudder, the wing and the high feature of thermal structure requirement of strength, nonmetal rudder sheet is applied increasingly general in armament systems.The structure of common nonmetal rudder sheet is as shown in attached Fig. 1 and 2, formed by rudder sheet 1 and the rudderpost 2 that is positioned at its lower edge face, because rudder sheet 1 needs to bear larger thermal shock power in the course of the work, after assembling, require rudder sheet 1 and control cabinet housing solid and reliable, rudder sheet 1 median plane and body symmetry are not more than 0.1mm, the rudderpost 2 that is positioned at rudder sheet 1 lower edge plane is interference fit with control cabinet housing, and rudder sheet 1 dimensional tolerance is only 6 grades.Because rudder sheet 1 external form is pneumatic profile, therefore very high to the requirement of rudder sheet 1 overall dimensions precision and surface quality again.Because rudderpost 2 structures are little, precision is high, the rudder face of rudder sheet 1 is irregular special-shaped profile, in process, technological datum face cannot be determined, therefore very high to the requirement of rudder slice processing method, and the difficult point of nonmetal special-shaped rudder flake products processing is the control of overall dimensions, rudder face surface quality and rudder face and rudderpost symmetry precision.Nonmetallic materials rudder sheet hardness is about Mohs' hardness 9.5, and cutting ability is poor, and the cost of charp tool is high.Meet the demands in order to ensure Product Precision, not only best technological process and parameter will sought aspect product processing, need to manufacture a set of precision profile location special tooling accurately simultaneously, otherwise easily cause the inaccurate and rudderpost in location and rudder face symmetry defective.
Be not more than ± the 0.0055mm of designing requirement dimensional discrepancy of rudderpost, the Central Symmetry degree of the relative rudderpost of two rudder faces is not more than 0.1mm, upper limb, the lower edge size tolerance requirements of rudder sheet are all not more than 0.1mm, and lower edge angular deviation is not more than ± and 3 ', surface roughness requires as Ra3.2.At present, because of nonmetal special-shaped rudder chip architecture complexity, raw material hardness is high, design of part poor rigidity, add Jiang Duopian in man-hour center basal plane horizontal positioned, carry out Roughing and fine machining with tungsten carbide tipped tool and hard alloy cutter respectively, last pincers worker repair rudderpost, concrete technology journey is: profile → pincers worker repair rudderpost under profile → fine finishining in profile → fine finishining under profile → roughing in blank preparation → roughing.The problem that this technique exists is that after processing, product rudderpost size cannot ensure, the rudderpost non-interchangeability of pincers worker repair, and surface roughness is poor, and product weight difference is large, and processing cost is high, and efficiency is low.
Summary of the invention
Object of the present invention will provide a kind of nonmetal special-shaped rudder slice processing method exactly, and the method can effectively ensure machining accuracy and the form and position tolerance of nonmetal special-shaped rudder sheet, and the present invention simultaneously also provides a kind of nonmetal special-shaped rudder sheet fixture for processing,
