Horizontal supporting device suitable for processing shell with U-shaped structure, and installation method

Abstract

The invention provides a horizontal supporting device suitable for processing a shell with a U-shaped structure, and an installation method. The horizontal supporting device is formed by a supportingbase, two glue holding blocks, two telescopic rods, a plurality of locking screws and two fine adjusting rods, wherein shoulder through holes are formed in two sides of the top part of the supportingbase; locking screw installation holes and fine adjusting rod installation holes are formed in side walls of the shoulder through holes; one telescopic rod is inserted into the should through hole onone side of the supporting base; the outer end of each telescopic rod is fixedly connected with one glue holding block; racks are arranged on side walls of the telescopic rods; the end part of each fine adjusting rod is of a gear structure; and after the fine adjusting rods stretch into the fine adjusting rod installation holes in the side walls of the shoulder through holes of the supporting base, the fine adjusting rods can be matched with the racks on the side walls of the telescopic rods; and the fine adjusting rods are rotated to drive the telescopic rods to move axially. According to thehorizontal supporting device suitable for processing the shell with the U-shaped structure provided by the invention, the rigidity of a component cantilever part can be improved, the processing vibration is prevented, and the functions of damping and shock absorbing are realized, so that the processing requirement of a component with the U-shaped structure is met. The device is convenient, simple, reliable and flexible, the cantilever-structured component processing vibration can be effectively inhibited, and the cantilever-structured component processing accuracy is improved.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, in particular to a transverse support device and an installation method suitable for processing U-shaped structural shells. Background technique [0002] In the airborne photoelectric pod system, the structural part responsible for platform support is the "middle shell" part, which is U-shaped in structure. In order to meet the precision requirements of the photoelectric pod, there are strict requirements on the parallelism and verticality of the shaft system formed by the three-direction round holes on the two sides and the bottom of the part, both of which are less than 0.02mm; It is a weakly rigid thin-walled shell part made of magnesium alloy. [0003] When the part is processed, the traditional clamping method is not fixed and supported in the direction parallel to the machine bed surface, resulting in the round holes on the cantilevers on both sides of the U-shaped structure being d...
