[0025] The mounting block 10 has a flat surface 60 formed on the top thereof, and a downwardly recessed sealing groove 80 formed on the flat surface 60. The shape of the sealing groove 80 corresponds to the shape of the opening of the thin-walled box-shaped part 100. The inner plane surrounded by the sealing groove 80 is the adsorption plane 50. The surface of the adsorption plane 50 is formed with adsorption holes. The mounting block 10 also has an exhaust hole 101 formed thereon, and the exhaust hole 101 is in communication with the adsorption hole.

[0026] A connecting pipe (not shown in the figure) is connected to the air extraction hole 101;

[0028] The present embodiment provides a clamping tool for thin-walled box-shaped parts, which includes a mounting block 10, a connecting pipe and a vacuum pump. When clamping the thin-walled box-shaped part 100, the thin-walled box-shaped part 100 is inverted so that the open end of the thin-walled box-shaped part 100 faces downward, and the open end of the thin-walled box-shaped part 100 is placed in the sealing groove 80 to define a sealed space. The sealed space is the space above the adsorption plane 50. Since the vacuum pump is connected to the exhaust hole 101 through the connecting pipe, and the exhaust hole 101 is connected to the adsorption hole on the adsorption plane 50, the sealed space is vacuumed by starting the vacuum pump so that the thin-walled box-shaped part 100 is adsorbed and positioned. After adsorption and positioning, the surface of the thin-walled box-shaped part 100 can be processed, which can not only improve the clamping efficiency but also effectively prevent the deformation of the thin-walled box-shaped part 100 during the clamping process.

[0029] In a further embodiment of the present invention, there are multiple air extraction holes 101 , and the multiple air extraction holes 101 are provided on the bottom surface of the mounting block 10 .

[0033] In a further embodiment of this embodiment, the clamping tool for the thin-walled box-shaped part also includes a pressure block 20, which is arranged on the mounting block 10 and located on the first side of the sealing groove 80. The pressure block 20 is used to apply pressure to one side surface of the thin-walled box-shaped part 100.

[0034] In this embodiment, the pressing block 20 is used to apply pressure to one side surface of the thin-walled box-shaped part 100, which can make the clamping more stable.

[0039] In this embodiment, the thickness of the first portion 701 is greater than that of the second portion 702. The second portion contacts the side of the thin-walled box-shaped part 100, which can make the force point closer to the sealing groove 80 and effectively prevent the thin-walled box-shaped part 100 from deforming during the force application process.

[0040] In a further embodiment of the present invention, a plurality of mounting holes 703 are formed on the first portion 701 , and fasteners are provided in the mounting holes 703 . The clamping strip 70 is fixed to the flat surface 60 of the mounting block 10 through the fasteners.
