Device for installing cylindrical flange

Abstract

The invention provides a device for installing a cylindrical flange. The device comprises a mounting mechanism and a transmission mechanism, wherein the mounting mechanism comprises a mounting angle seat, a positioning block, a positioning plate, a handle, a handle screw, horizontal clamp forceps and a lifting ring, wherein the mounting angle seat serves as a mounting platform, the handle and thepositioning plate are fixed at the side, provided with a rib, of the mounting angle seat, the positioning block and the horizontal clamp forceps are fixed at the other side of the mounting angle seat,the positioning block is located in the vertical center line of the mounting angle seat, and the horizontal clamp forceps are uniformly distributed on the left and right sides of the mounting angle seat by taking the center of the mounting angle seat as the center of a circle and taking a fixed radius as a datum; the transmission mechanism comprises an angle seat supporting plate, a guide rail, ahand wheel, a ball screw, a drive sliding block, a guide rail sliding block, a limiting angle bracket and a bearing base, wherein the guide rail and the limiting angle bracket are arranged on a workbench, the guide rail sliding block is embedded in the guide rail and moves front and back along the back and rear of the guide rail, the angle seat supporting plate is fixed on the guide rail slidingblock, the drive sliding block is fixed on the angle seat supporting plate, and the whole mounting mechanism is vertically placed on the angle seat supporting plate of the transmission mechanism.

Description

technical field [0001] The invention relates to the field of space vehicle assembly technology, in particular to a device for cylindrical flange installation. Background technique [0002] In the manufacturing process of aerospace vehicles, the design and manufacture of aircraft process equipment manufacturing has always occupied an important position, and its technical level directly affects the assembly quality and model development progress of aircraft. The original aircraft structure is cylindrical or conical, and the assembly tooling is also designed to be of the same type according to the structural characteristics of the aircraft. Now there is an aircraft structure with a cylindrical flange installed on the outside of the cylindrical section. The middle cylinder section is formed by screwing the upper and lower end frames and four arc-shaped wall panels. The cylindrical flange is an integral machined structure, which is characterized by a flat surface at one end, a cy...
