Description

Technical Field

[0001] This application relates to the field of aerospace manufacturing technology, and in particular to an automatic flipping device for large composite material panels and its usage method. Background Technology

[0002] In aircraft assembly, especially in horizontal assembly structures, there are various processes involving the flipping and lifting of composite material panels during demolding, assembly removal, cleaning and deburring, and mounting of upper surface panels. Due to the large cross-sectional dimensions and thin thickness of aircraft panels, ensuring the stability of the panel shape during the flipping process has always been a challenge. Currently, most domestic aircraft panel flipping methods involve multiple actions, including flipping suspension, slings combined with brackets, and manual assistance. These auxiliary actions and processes are numerous. Furthermore, because the panel dimensions, curvature, flipping height, and combinations of flipping and lifting processes vary, it is difficult to standardize the flipping structure and equipment, resulting in a high degree of uniformity for large panels. Currently, the production volume of large aircraft in China is small, and the configurations are diverse. Based on factors such as cost reduction, improved development efficiency, and shortened development cycles, developing a reasonable and universal flexible large composite material panel flipping equipment is an inevitable technical challenge in large aircraft manufacturing. Therefore, it is necessary to develop an automatic large composite material panel flipping device and its operating method. Summary of the Invention

The wall panel is initially fixed horizontally on the tilting and adjusting beam, parallel to the ground moving device in the tilting device. The steel cable on the cable-driven column is retracted, and the ground moving device moves towards the cable-driven column, driving the tilting and adjusting beam and the wall panel on it to tilt until it is vertical.

The lower frame is a rectangular plate welded structure, with two layers of perforated steel plates welded to ribs on the left and right sides respectively. The back has two thick steel plates with guide rail mounting surfaces welded to it, and the front has a steel plate with a maintenance opening.

[0009] A method of using an automatic flipping device for large composite material wall panels, characterized by comprising the following:

[0010] 1. Move the movable bracket to the marked position on the ground;

[0011] 2. Hoist the wall panel directly above the multiple sets of tilting and adjusting beams and fix it thereto;

[0012] In the multiple sets of tilting devices, the motor-driven screw in the cable-driven column drives the pulley to tighten the cable, so that the multiple sets of tilting and attitude-adjusting beams can be tilted upward synchronously with the slewing bearing in the ground moving device as the axis of rotation; the bearing mounting seat assembly and the moving assembly in the multiple sets of ground moving devices are driven by the motor to drive the gear to rotate, so that the axis of rotation of the multiple sets of tilting and attitude-adjusting beams, namely the slewing bearing, can move linearly synchronously in the ground moving device.

[0013] 4. The steel cables in the column drive multiple sets of rotating and adjusting beams to rotate synchronously upward with the slewing bearings in the ground moving device as the rotating axis. At the same time, the multiple slewing bearings move synchronously in a straight line on the ground moving device, so that the steel cables are always perpendicular to the ground until the rotating and adjusting beams are vertical.

[0014] 5. The steel cable in the column is stationary, while multiple sets of slewing bearings continue to move synchronously in a straight line on the ground moving device until the angle between the tilting and adjusting beam and the vertical direction is greater than 3°.

[0015] The 6 slewing bearings remain stationary on the ground moving device. Multiple sets of steel cables drive the steel cables in the column to loosen, causing the tilting and adjusting beam to tilt downwards synchronously with the slewing bearings in the ground moving device as the axis of rotation.

[0016] 7. When the tilting and adjusting beam is horizontal, the steel cable in the column driven by the steel cable remains stationary.

[0017] 8. Manually raise the movable bracket until it contacts the wall panel;

[0018] 9. Disconnect the wall panel from the multiple sets of tilting and adjusting beams;

[0019] More than 10 sets of steel cables drive the steel cables in the column to tighten, causing the tilting and adjusting beam to tilt upwards to a vertical position with the slewing bearing in the ground moving device as the axis of rotation.

[0020] 11. Complete the 180° rotation of the wall panel.

[0021] The advantage of this application lies in the use of a combination of rigid and flexible methods, such as cable drive and ground sliding synchronous control, to achieve 90° and 180° rotation of large composite wall panels while minimizing the equipment footprint. This ensures the safety of the wall panels while saving resources. It is characterized by strong versatility, relatively low cost, and full automation, and is universally applicable to the rotation of composite wall panel skins and even ordinary metal wall panels.

3. The automatic flipping device for large composite material wall panels according to claim 1 or 2, characterized in that... One end of the tilting and adjusting beam is connected to one end of the steel cable on the steel cable drive column, and the other end is hinged to the ground moving device through two slewing bearings on the bearing mounting seat assembly.

4. A method of using an automatic flipping device for large composite material wall panels as described in any one of claims 1 to 3, characterized in that... Includes the following: 4-1 Move the movable bracket to the marked position on the ground; 4-2 Hoist the wall panel directly above the multiple sets of tilting and adjusting beams and fix it thereto; 4-3 In the multi-set tilting device, the motor-driven screw in the cable-driven column moves the pulley to tighten the cable, so that the multiple tilting and attitude-adjusting beams can be tilted upward synchronously with the slewing bearing in the ground moving device as the axis of rotation; the bearing mounting seat assembly and the moving assembly in the multiple sets of ground moving devices are driven by the motor to drive the gear to rotate, so that the axis of rotation of the multiple sets of tilting and attitude-adjusting beams, i.e. the slewing bearing, can move linearly synchronously in the ground moving device. 4-4 Multiple sets of steel cables drive the columns. The steel cables drive multiple sets of tilting and adjusting beams to tilt upwards synchronously with the slewing bearings in the ground moving device as the pivot. At the same time, the multiple sets of slewing bearings move linearly synchronously on the ground moving device, so that the steel cables are always perpendicular to the ground until the tilting and adjusting beams are vertical. 4-5 The steel cable in the steel cable driven column remains stationary, while multiple sets of slewing bearings continue to move synchronously in a straight line on the ground moving device until the angle between the tilting and adjusting beam and the vertical direction is greater than 3°; 4-6 The slewing bearing remains stationary on the ground moving device. Multiple sets of steel cables drive the steel cables in the column to loosen, causing the tilting and adjusting beam to tilt downward synchronously with the slewing bearing in the ground moving device as the axis of rotation. 4-7 When the tilting and adjusting beam is horizontal, the steel cable in the steel cable-driven column remains stationary; 4-8 Manually raise the movable bracket until it contacts the wall panel; 4-9 Disconnect the wall panel from the multiple sets of tilting and adjusting beams; 4-10 Multiple sets of steel cables drive the steel cables in the column to tighten, causing the tilting and adjusting beam to tilt upwards to a vertical position with the slewing bearing in the ground moving device as the axis of rotation. 4-11 Complete the 180° rotation of the wall panel.
