Abstract

The invention relates to a polishing device for an arc-shaped slot array antenna mounting plate. The polishing device is characterized in that each conveying mechanism comprises a pair of parallel conveying wheels used for conveying the antenna mounting plate, the distance between the conveying wheels is adjustable, the conveying wheels are connected with driving motors, and multiple sets of conveying mechanisms are arranged; at least one set of inner cambered surface polishing mechanisms are arranged, each inner cambered surface polishing mechanism comprises a portal frame and a rotating part, a plurality of polishing brushes are uniformly arranged on each rotating part along the circumference, and the distance between the head of each polishing brush and a rotating shaft of the corresponding rotating part is adjustable; and at least one set of outer cambered surface polishing mechanisms are located between the conveying mechanisms, at least one set of conveying mechanisms are arranged between the inner cambered surface polishing mechanisms and the outer cambered surface polishing mechanisms, each outer cambered surface polishing mechanism comprises an outer ring base and an innerring coaxially and rotationally arranged in the outer ring base, a lifting mechanism is arranged at the bottom of each outer ring base, a plurality of polishing brushes are evenly arranged on the inner wall of each inner ring in the circumferential direction, and the positions of the polishing brushes in the normal direction of the corresponding inner ring are adjustable. According to the polishing device, mounting plates of different thicknesses and different structures can be polished, and the polishing efficiency is high.

Description

technical field [0001] The invention belongs to the field of slot positive antenna manufacturing and processing, and in particular relates to a polishing device for an arc-shaped slot array antenna mounting plate. Background technique [0002] The slotted array antenna is usually a planar array structure. With the gradual expansion of antenna coverage, more and more slotted array antennas are required to be installed on a curved surface, which requires that the antenna mounting plate used to install the slotted antenna be processed into a design The arc-shaped structure of the antenna is used to obtain the arc-shaped slot array antenna. In order to improve the accuracy of the slot array antenna, there are also high requirements for the machining accuracy of the inner and outer arc surfaces of the antenna mounting plate. At present, most antenna mounting plates are cast or Formed by bending the board. The precision of the inner and outer curved surfaces of the antenna mounti...
