[0002] Aircraft skin refers to a dimensional component that surrounds the aircraft frame structure and is fixed to the frame with adhesives or rivets to form the aircraft's aerodynamic shape. The skin structure composed of the aircraft skin and the frame has a large bearing capacity and rigidity, but is very light in weight, and plays a role in bearing and transmitting aerodynamic loads.

[0003] The manufacturing process of aircraft skin is usually: rolling - annealing - cleaning - solution heat treatment - stretching - natural aging - machining - surface treatment. In the heat treatment process of materials, most of them use tray-shaped tooling to place materials. After annealing, the materials will be removed for cleaning and then placed on the tooling for solution heat treatment. This is relatively cumbersome, and scratches may be caused by the movement of materials during the material removal process.

[0016] The present invention provides an aircraft skin shaping heat treatment tool that is easy to position, and has the following beneficial effects: when in use, it is easy to position and stack the bottom frame, so as to prevent the bottom frame from shaking due to position deviation during stacking and causing it to fall.

[0017] 1. When the present invention is in use, the bottom frames can be engaged with each other through positioning rods and positioning holes, so as to position and stack the bottom frames, thereby avoiding position deviation of the bottom frames when stacking, causing shaking when the bottom frames are moved and causing the upper bottom frames to fall, resulting in damage to the bottom frames or processing equipment, and the length of the positioning rods is greater than the depth of the positioning holes, so that when the bottom frames are stacked, gaps can be left between the bottom frames, which is convenient for heating the materials in the bottom frames and avoids uneven heating of the materials.

[0018] 2. When placing materials, the present invention can lift the materials and move the materials along the rails to the top of the bottom frame, and then lower the materials to the inside of the bottom frame, and the hydraulic rod can drive the clamping plate to move toward the materials to clamp them, and the distances of the clamping plates pushed by the opposite hydraulic rods are consistent, so that when placing materials of different specifications, the clamping plates can fix the materials at the center of the bottom frame, and after clamping, the heat can be directly transferred to the materials through the through grooves, avoiding uneven heating of the materials caused by the clamping plates, maintaining the heating effect on the materials, and when the clamping plates move, they can drive the connecting pipes to slide in the connecting chamber, and the clamping blocks limit the connecting pipes through the clamping grooves, thereby limiting the clamping plates and avoiding the deviation of the clamping plates.

[0019] 3. After the material is clamped and stabilized and the bottom frame is stacked, the lifting trolley can lift the bottom frame through the hook and the hook, move the bottom frame above the pallet and place the bottom frame on the pallet through the positioning rod and the positioning groove. The trumpet mouth on the upper part of the positioning groove can assist the positioning rod to slide into the positioning groove, so that the positioning and placement can be completed more quickly. After the bottom frame is placed on the pallet, it can slide into the annealing furnace or the solution treatment furnace through the slide rail and the pulley for heat treatment.

[0020] 4. According to the present invention, after the material is taken out from the annealing furnace, it is not necessary to take it out from the bottom frame for cleaning. It is only necessary to insert the ventilation hood and the dust box onto the bottom frame through the fence and the surrounding frame respectively, and then connect the air inlet to the external fan. The airflow enters the air outlet from the air inlet through the branch channel, and then blows from the connecting cavity through the connecting pipe from the air vent to the material. While cooling the material, impurities on the surface of the material are blown away, and the impurities are blown into the dust box from the air vent on the opposite clamping plate through the dust port. After the impurities enter the dust box, they are guided to the right side of the guide plate by the guide plate, and then the airflow leaves the dust box from the air outlet, and the filter intercepts the impurities in the dust box. The material can be cleaned while being cooled.

[0021] 5. In the present invention, when the lifting trolley moves the bottom frame, when the material moves to the top of the pallet, the telescopic rod can move the I-shaped plate in the slide groove, thereby driving the vertical plate to move. After the lifting trolley contacts the buffer plate, the resistance spring buffers the impact force with the cooperation of the resistance rod, and assists the braking of the lifting trolley to avoid the position deviation of the lifting trolley that causes the bottom frame to be unable to be stably placed on the pallet. After the lifting trolley is completely stationary, the telescopic rod can drive the I-shaped plate to return to its original position, avoiding obstruction to the movement of the lifting trolley.

The airflow enters the air outlet 20 from the air inlet 18 through the branch channel 19, and then blows from the connecting cavity through the connecting pipe from the vent 404 to the material. While cooling the material, the impurities on the surface of the material are blown away, and the impurities are blown into the dust box 21 from the vent 404 on the opposite clamping plate 402 through the dust port 23.

[0036] In summary, when the aircraft skin shaping heat treatment tooling that is easy to position is used, the material is first lifted by the lifting trolley 13 and moved along the track 12 to the top of the bottom frame 3, and then the material is lowered to the inside of the bottom frame 3, and the hydraulic rod 401 can drive the clamping plate 402 to move toward the material to clamp it, and the distance that the clamping plate 402 is pushed by the opposite hydraulic rod 401 is consistent, so that when placing materials of different specifications, the clamping plate 402 can fix the material at the center of the bottom frame 3, and after clamping, the heat can be directly transferred to the material through the through groove 403, so as to avoid uneven heating of the material caused by the clamping plate 402 and maintain the heating effect on the material, and when the clamping plate 402 moves, it can drive the connecting pipe to slide in the connecting cavity, and the clamping block 406 passes through the clamping groove 408 restricts the connecting pipe, thereby restricting the clamping plate 402 to prevent the clamping plate 402 from being skewed, and then the bottom frame 3 is engaged through the positioning rod 409 and the positioning hole 410, so as to position and stack the bottom frame 3 to avoid position deviation of the bottom frame 3 when stacking, which causes shaking when the bottom frame 3 is moved and causes the upper bottom frame 3 to fall, causing damage to the bottom frame 3 or the processing equipment, and the length of the positioning rod 409 is greater than the depth of the positioning hole 410, so that when the bottom frames 3 are stacked, gaps can be left between the bottom frames 3, which is convenient for heating the materials in the bottom frames 3 and avoids uneven heating of the materials. After the materials are clamped stably and the bottom frames 3 are stacked, the lifting trolley 13 can lift the bottom frame 3 through the hook 14 and the hook 5, and move the bottom frame 3 to the top of the pallet 9. The bottom frame 3 is placed on the support plate 9 through the positioning rod 409 and the positioning groove 10.

After the bottom frame 3 is placed on the support plate 9, it can slide into the annealing furnace 2 or the solution treatment furnace 6 through the slide rail 7 and the pulley 8 for heat treatment. After the material is taken out of the annealing furnace 2, it is not necessary to take it out from the bottom frame 3 for cleaning. It is only necessary to insert the ventilation hood 16 and the dust box 21 into the bottom frame 3 through the fence 17 and the surrounding frame 22 respectively, and then connect the air inlet 18 to the external fan. The airflow enters the air outlet 20 from the air inlet 18 through the diverter 19, and then blows from the connecting cavity through the connecting pipe from the vent 404 to the material, cooling the material while Impurities on the surface of the material are blown away and blown into the dust box 21 through the vent 404 on the opposite clamping plate 402 through the dust collecting port 23. After the impurities enter the dust box 21, they are guided to the right side of the guide plate 24 by the guide plate 24, and then the airflow leaves the dust box 21 from the air outlet 25. The filter 26 intercepts the impurities in the dust box 21, and the material can be cleaned while being cooled. When the lifting trolley 13 moves the bottom frame 3, when the material moves to the top of the tray, the telescopic rod 1503 can move the I-plate 1502 in the slide 1501, thereby driving the vertical plate 1504 to move. After the lifting trolley 13 contacts the buffer plate 1507, the resistance spring 1505, in cooperation with the resistance rod 1506, buffers the impact force, thereby assisting the lifting trolley 13 in braking.Avoid the position deviation of the hoisting trolley 13, which causes the bottom frame 3 to be unable to be stably placed on the pallet. After the hoisting trolley 13 is completely stationary, the telescopic rod 1503 can drive the I-shaped plate 1502 to reset, avoiding obstruction to the movement of the hoisting trolley 13.
