It should be understood that the data used in this way can be interchanged where appropriate, so as to describe the embodiments of the utility model described herein. In addition, similar terms such as "including" and "having" mean that in addition to those contents already listed in "including" and "having", other contents that have not been listed can also be "included" and "having"; for example, a process, method, system, product or device that can include a series of steps or units is not necessarily limited to those steps or units that have been clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0019] Due to the angle of the drawing, some components may not be drawn, but their positions and connection relationships can be partially understood based on the text expression.

[0020] like Figure 1-Figure 2 As shown, the utility model is a tool for clamping thin-walled parts, comprising a base plate 2, on which a positioning component and a clamping component are installed.

[0021] The positioning assembly comprises a first positioning cylinder 3 and a second positioning cylinder 4. The first positioning cylinder 3 and the second positioning cylinder 4 are arranged back to back. The first positioning cylinder 3 and the second positioning cylinder 4 have a first positioning plate 5 and a second positioning plate 6 respectively installed on their piston ends.

[0022] The clamping assembly includes a first fixed clamping plate 9, a second fixed clamping plate 10, a first clamping cylinder 15, and a second clamping cylinder 16. The first fixed clamping plate 9 and the second fixed clamping plate 10 are located on the sides of the first positioning cylinder 3 and the second positioning cylinder 4. The piston end of the first clamping cylinder 15 faces the first fixed clamping plate 9 and is installed with the first movable clamping plate 11. The piston end of the second clamping cylinder 16 faces the second fixed clamping plate 10 and is installed with the second movable clamping plate 12.

[0023] The bottom plate 2 is a rectangular plate.

[0024] The first positioning cylinder 3 , the second positioning cylinder 4 , the first clamping cylinder 15 , and the second clamping cylinder 16 are mounted on the base plate 2 via the first cylinder seat 7 , the second cylinder seat 8 , the third cylinder seat 13 , and the fourth cylinder seat 14 , respectively.

[0025] The first positioning cylinder 3 and the second positioning cylinder 4 are rotary cylinders.

[0026] The first fixed clamping plate 9 , the second fixed clamping plate 10 , the first movable clamping plate 11 , and the second movable clamping plate 12 are contoured structures adapted to the outer shape of the workpiece 2 .

[0027] The working process of the utility model is as follows:

[0028] Before clamping, the first positioning cylinder 3 is in a retracted state, and the other cylinders are in an extended state. Put the workpiece 2 between the first fixed clamping plate 9, the second fixed clamping plate 10, the first movable clamping plate 11, and the second movable clamping plate 12, with one end of the workpiece 2 attached to the first positioning plate 5, and one side of the workpiece 2 attached to the first fixed clamping plate 9 and the second fixed clamping plate 10. Then the second positioning cylinder 4 retracts and rotates with the second positioning plate 6, and the second positioning plate 6 and the first positioning plate 5 position the two ends of the workpiece 2; then the first clamping cylinder 15 and the second clamping cylinder 16 drive the first movable clamping plate 11 and the second movable clamping plate 12 to extend until the first fixed clamping plate 9, the second fixed clamping plate 10, the first movable clamping plate 11, and the second movable clamping plate 12 clamp the workpiece 2. After clamping is completed, the first positioning cylinder 3 and the second positioning cylinder 4 rotate with the first positioning plate 5 and the second positioning plate 6 to separate from the workpiece 2 to avoid interference during subsequent processing of the workpiece 2.
