Problems solved by technology
The handling, installation or removal of these load-bearing columns weighing tens of kilograms is time-consuming and labor-intensive for manual workers. It is not only labor-intensive and inefficient, but also has potential safety hazards.
[0003] For example, the applicant's existing invention patent "a flexible combined prestressing fixture" (patent number: ZL200610087318.3), which provides a versatile flexible combined prestressing fixture for shot peening of aircraft panels, but it There are still deficiencies, such as the column is connected to the slide rail of the beam through the bolt, when the position of the column needs to be switched, it is necessary to manually remove, carry and reinstall the column, which is time-consuming, laborious and inefficient, and is not suitable for production lines. use

Embodiment Construction
[0012] Referring to the accompanying drawings, the pneumatic flexible load-bearing fixture includes a rigid frame 1 and a plurality of rigid load-bearing pillars 4. The rigid frame is preferably a quadrilateral structure in implementation, and contains parallel and symmetrical upper beams 2 and lower beams 3. On the upper beam 2 The upper rail 5 parallel to the upper beam is fixed on the inner side of the upper rail, and a plurality of positioning holes 7 perpendicular to the direction of the rail are arranged on the upper beam body below the upper rail. The center line of the positioning hole is parallel to the upper rail The lower rail is also provided with a lower rail 6 corresponding to the upper rail and a positioning hole 7 on the inner side of the lower beam. The positioning hole 7 of the lower beam is located above the lower rail 6. The two ends of the rigid load-bearing pillar 4 are respectively provided with Fix the slide block 8 and the positioning cylinder 9, the sl...

A pneumatic flexible force bearing clamp comprises a rigid frame and a plurality of rigid force bearing supporting columns. The rigid frame comprises an upper beam and a lower beam, wherein the upper beam and the lower beam are parallel and symmetrical. The two ends of the rigid force bearing supporting columns are connected with the upper beam and the lower beam through sliding rail pairs. In addition, the upper beam and the lower beam are provided with a plurality of positioning holes, positioning air cylinders are arranged at the two ends of each rigid force bearing supporting column respectively, and a telescopic pin of each positioning air cylinder corresponds to the corresponding positioning hole.
Description
technical field [0001] The application relates to aircraft manufacturing tooling technology, in particular to an aerodynamic flexible load-bearing fixture for assembling large panel parts. Background technique [0002] Such a type of fixture is often used in the traditional aircraft assembly manufacturing industry: frame fixtures containing multiple load-bearing columns. The docking of large parts and the type-guaranteed transportation of aircraft products are all essential. Whether it is for assembly, forming, or docking, transportation, aircraft products have two indispensable links in place and out of place on the fixture, so the load-bearing columns are loose parts and must be unloaded. When the aircraft product is in place , the load-bearing column in the fixture is hoisted, installed and fastened by the worker, and when the aircraft product is out of place, the load-bearing column in the tooling is removed, carried and hoisted away by the worker. The handling, instal...
