Problems solved by technology

[0004] However, the installation space of the existing positioner is limited, and the accuracy of the existing tooling positioner exceeds the design index range after long-term use of grinding, vibration, etc., the workload of regular inspection and repair is large, and maintenance is inconvenient, which will increase virtually. Reduce the cost of tooling life cycle use

Embodiment 1

[0030] A large-curvature aircraft fuselage assembly double-rail locator unit, including a first mounting seat 1 installed on a tooling platform, a column 3 installed at the free end of the first mounting seat 1, a second mounting seat 2 arranged on the top of the column 3, The cantilever 4 arranged on the second mount 2;

[0031] Such as image 3 As shown, the column 3 is slidably connected with the first mounting seat 1 through a first sliding mechanism, and the first sliding mechanism includes a first guide rail 8 fixedly installed on the first mounting seat 1, a first guide rail 8 installed at the bottom of the column 3 A sliding block 9; the column 3 is slidably connected with the first guide rail 8 through the first sliding block 9, so that the column 3 can slide back and forth on the first mounting seat 1; the column 3 is fixedly provided with a positioning pin 6;

[0032] A cantilever 4 is installed on the second mounting base 2, and the cantilever 4 is slidably connec...

Embodiment 2

[0038]This embodiment is further optimized on the basis of Embodiment 1. The first mounting seat 1 and the second mounting seat 2 are arranged in parallel, and the first guide rail 8 and the second guide rail 10 are vertically arranged, so that the positioner can be realized front and rear, left and right Position adjustment, the locator can flexibly adjust the position according to the needs, which improves the degree of freedom of the locator and effectively improves the efficiency of tooling assembly.

[0039] Other parts of this embodiment are the same as those of Embodiment 1, so they will not be repeated here.

Embodiment 3

[0041] This embodiment is further optimized on the basis of embodiment 1, as figure 1 , figure 2 As shown, the column 3 includes two sections, and the sections are fixedly connected between the sections. A section of the column 3 is vertically arranged on the first mounting seat 1, and this section is connected to the first rail 8 through the slider mechanism of the first guide rail 8. The mounting base 1 is slidingly connected; the other section of the column 3 is inclined according to the needs of assembly, and is slidingly connected with the second mounting base 2 through the second guide rail 10 slider mechanism; the first mounting base 1 and the second mounting base 2 are arranged in parallel, the positioner can realize front and rear adjustment; both ends of the first guide rail 8 are provided with stoppers 12, which can prevent the first sliding block 9 from sliding out of the first mounting seat 1.

[0042] The invention adjusts the size and angle of the column 3 acc...

Abstract

The invention discloses a large-curvature aircraft fuselage double-track positioner unit, which comprises a first mounting base mounted on a tooling platform, a vertical column mounted on a free end of the first mounting base, a second mounting base arranged on the top of the vertical column, and a cantilever arranged on the second mounting seat. The vertical column is slidably connected with thefirst mounting seat through a first sliding mechanism. A positioning pin is fixedly arranged on the vertical column. The cantilever is mounted on the second mounting seat. The cantilever is slidably connected with the second mounting seat through a second sliding mechanism. Symmetrical cantilever positioning quick locking pins are arranged on the second mounting seat and on both sides of the cantilever. The cantilever is provided with a product positioning pin bolt at a working end. According to the invention, the retractable distance and the reachable size of the positioner are improved, thetooling space is enlarged, meanwhile, the post-maintenance cost of the positioned is reduced, and the service life of the positioned is prolonged.

Description

technical field [0001] The invention belongs to the technical field of aircraft component assembly tooling locators, and in particular relates to a large-curvature aircraft fuselage assembly double-rail locator unit. Background technique [0002] Aircraft component assembly refers to the precise positioning and riveting of the manufactured aircraft components in the assembly jig to form a complete whole with precise component dimensions, so as to enter the final assembly of the next wheel. In the process of assembling the skeleton, the aircraft assembly jig is first required to accurately position important parts such as the aircraft frame beam, and then the outer skin is positioned and riveted based on the frame beam structure. [0003] Aircraft fuselage components, especially small and medium-sized aircraft fuselage components, have a cylindrical shape with large curvature. Then set the process positioning point along the circumference of the fuselage. The positioner is s...
