After the thin-walled structural part is produced, it is often necessary to perform machining processes such as grinding, drilling, or polishing on the thin-walled structural part. To ensure the machining accuracy, before machining the thin-walled structural part, it is necessary to clamp the thin-walled structural part.
[0003] However, there are some problems in the clamping process of existing thin-walled structural parts. The thin-walled structural parts themselves are relatively fragile, and during the machining of thin-walled structural parts, due to improper clamping force of the clamping device, the thin-walled structural parts are prone to deformation, affecting the accuracy. At the same time, the existing clamping devices are not convenient for clamping thin-walled structural parts of different shapes. Currently, the clamping devices usually only have the function of clamping thin-walled structural parts of one or two shapes, and it is not convenient to adjust their own forms in cooperation with thin-walled structural parts of different shapes, reducing the application range of the device.

A number of jacks are provided on the outer edges of the movable plates 6. Slots are provided on the outer edges of the support disc 1. Plug plates 23 are fixedly connected to the sides of the movable plates 6 close to the support disc 1. The plug plates 23 are located in the adjacent slots.

Elastic plates 29 are fixedly connected to the outer edges of the vertical tubes 28. Sealing plugs 30 are fixedly connected to the sides of the elastic plates 29 away from the vertical tubes 28;
[0034] The first arc-shaped plate 16 and the second arc-shaped plate 17 can clamp thin-walled structural parts of different circular sizes. The bolt 21 adjusts the distance between the first arc-shaped plate 16 and the second arc-shaped plate 17. At the same time, the movable plate 6 can be disassembled from the support plate 3 and installed on the fixed disc 5, so as to adapt to more thin-walled structural parts of different shapes.
[0035] Working principle: When the device starts to work, the operator holds the handle 40 and pushes the handle 40 towards the support plate 1. The handle 40 drives the swing plate 38 to swing through the U-shaped plate 39. The swing plate 38 cooperates with the U-shaped block 37 and the threaded rod 36 to adjust the distance between the cross plates 34, and the second spring 35 is stretched. The upper and lower support plates 1 will move away from each other. When clamping a thin-walled structural member on a horizontal plane, place the thin-walled structural member between several upper and lower air bags 24. Start the inflator 2. The inflator 2 injects gas into the air bags 24 through the telescopic tube 12, the L-shaped tube 13 and the vertical tube 28. The air bags 24 gradually expand, thereby clamping the thin-walled structural member. If the area of the thin-walled structural member on the horizontal plane is large, the operator moves the movable plate 6. The movable plate 6 drives the T-shaped block 25 to move. The T-shaped block 25 moves in the T-shaped groove on the side wall of the support plate 3. After the movable plate 6 moves to a suitable position, it pushes the grip 33. The grip 33 drives the insertion rod 32 to move, and inserts the insertion rod 32 into the hole on the surface of the movable plate 6, thereby limiting the movable plate 6. When the movable plate 6 moves, the movable plate 6 drives the vertical tube 28 to move. The vertical tube 28 drives the L-shaped tube 13 to move through the first magnet 15 and the second magnet 27. The L-shaped tube 13 drives the telescopic tube 12 to stretch, so as to cooperate with thin-walled structural members of different sizes and areas. When clamping a circular thin-walled structural member, place the circular thin-walled structural member between several first arc plates 16 and second arc plates 17 on the same side. The first arc plates 16 and the second arc plates 17 are used to cooperate with circular thin-walled structural members of different diameters. Move the first arc plate 16 and the second arc plate 17. The second arc plate 17 drives the slider 19 to move. The slider 19 drives the first spring 18 to be compressed. Then rotate the bolt 21. The bolt 21 drives the first arc plate 16 to gradually move towards the second arc plate 17, thereby clamping the circular thin-walled structural member. If it is necessary to clamp thin-walled structural members of other shapes, the operator moves the movable plate 6. The movable plate 6 drives the T-shaped block 25 to move. The T-shaped block 25 is completely moved out of the support plate 3. Then adjust the position of the movable plate 6. Place the elastic Z-shaped plate 7 in the upper fixed plate 5. The fixing plate 8 limits the elastic Z-shaped plate 7. Multiple movable plates 6 are simultaneously located on the top of the upper fixed plate 5, thereby expanding the clamping range for thin-walled structural members. After the air bags 24 are inflated, the vertical tube 28 is sealed by the sealing plug 30, thereby ensuring that the gas inside the air bags 24 will not leak out.
