Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Example:

[0028] As attached Figure 1 To Attachment Fig. 9 As shown:

[0029] A clamping device for sheet metal processing, comprising a mounting frame 1, a workbench 2 is fixedly connected to the top of the mounting frame 1, a cylinder 3 is fixedly installed on the upper surface of the mounting frame 1, a U-shaped push rod 4 is fixedly connected to the output end of the cylinder 3, a placement plate 7 is fixedly installed in the middle of the upper surface of the workbench 2, a through hole 8 is opened in the middle of the workbench 2, a notch 9 is opened on one side of the workbench 2, a push rod 10 is slidably connected to the lower surface of the workbench 2, a movable part 12 is fixedly sleeved on the outer wall of the push rod 10, a spring 13 is sleeved on the outer wall of the push rod 10, the spring 13 is located on the left side of the movable part 12, and the push rod 10 The other end of the movable member 12 is fixedly connected with a connecting block 14, and a movable plate 15 is fixedly connected to the upper surface of the connecting block 14. Connecting rods 16 are movably connected to both sides of the movable member 12, and a slider 17 is movably connected to the other end of the connecting rod 16. Side panels 18 are fixedly installed on both outer side walls of the workbench 2, and a sliding rod 19 is fixedly connected to the outer wall of the side panel 18, and the other end of the sliding rod 19 is slidably connected to the slider 17.

[0030] In the above technical scheme, the sheet metal to be clamped is placed on the upper surface of the placement plate 7, and the cylinder 3 is started. The cylinder 3 drives the U-shaped push rod 4 to move to the right. At this time, the push rod 10 is not in contact with the U-shaped push rod 4. Under the action of the spring 13, the spring 13 pushes the movable part 12 to move to the right. The movable part 12 drives the slider 17 to approach each other through the connecting rod 16. The slider 17 drives the second clamping plates 21 on both sides to approach each other, and the sheet metal is clamped by the second clamping plate 21. At the same time, the push rod 10 drives the movable plate 15 to move to the right through the connecting block 14, and the movable plate 15 drives the first clamping plate 20 to move, and the sheet metal is further clamped by the first clamping plate 20 and the third clamping plate 22, thereby completing the positioning and fixation of the sheet metal.

[0031] As attached Figure 4 As shown, a buffer block 11 is fixedly sleeved on the outer wall of the push rod 10 , and the buffer block 11 is located on the right side of the movable part 12 .

[0032] In the above technical solution, the design of the buffer block 11 prevents the movable part 12 from directly contacting the outer wall of the workbench 2 , thereby protecting the movable part 12 .

[0033] As attached Figure 6 To Attachment Figure 7 As shown, there are two second clamps 21, and the two second clamps 21 correspond to each other, and the first clamp 20 and the third clamp 22 correspond to each other. The first clamp 20, the second clamp 21, and the third clamp 22 have the same structure. The first clamp 20 includes a bottom plate 2001, and an opening is provided on the outer wall of the bottom plate 2001. The outer wall of the bottom plate 2001 is slidably connected to an adjustment plate 2002. The outer wall of the bottom plate 2001 is threadedly connected to a fixing screw, and the fixing screw is in contact with the outer wall of the adjustment plate 2002.

[0034] In the above technical solution, when clamping sheet metal parts of different sizes, the fixing screws on the base plate 2001 are loosened. At this time, the length of the adjustment plate 2002 can be adjusted so that the sheet metal parts of different sizes can be fixed, thereby improving the application range of the clamping device.

[0035] As attached Figure 8 To Attachment Fig. 9 As shown, a rotating mechanism 5 is fixedly installed at the bottom of the mounting frame 1, an air slip ring 6 is fixedly installed inside the rotating mechanism 5, and the air slip ring 6 is connected to the cylinder 3 through a pipeline.

A motor 503 is fixedly installed on the upper surface of the base 501, and an output shaft 504 is fixedly connected to the output end of the motor 503. A gear 505 is fixedly sleeved on the outer wall of the output shaft 504, and the gear 505 and the outer ring teeth of the slewing bearing 502 are meshed with each other.

[0036] In the above technical solution, after clamping, when the angle of the sheet metal needs to be adjusted, the motor 503 is started, the motor 503 drives the gear 505 to rotate through the output shaft 504, the gear 505 drives the outer ring of the slewing support 502 to rotate, and the slewing support 502 drives the sheet metal placed above to rotate through the mounting frame 1, thereby adjusting the angle of the sheet metal, making it convenient for external equipment to process the sheet metal.

[0037] The specific usage and function of this embodiment are as follows:

[0038] When the utility model is used, the sheet metal to be clamped is placed on the upper surface of the placement plate 7, and the cylinder 3 is started. The cylinder 3 drives the U-shaped push rod 4 to move to the right. At this time, the push rod 10 is not in contact with the U-shaped push rod 4. Under the action of the spring 13, the spring 13 pushes the movable member 12 to move to the right. The movable member 12 drives the slider 17 to approach each other through the connecting rod 16. The slider 17 drives the second clamping plates 21 on both sides to approach each other, and the sheet metal is clamped by the second clamping plate 21. At the same time, the push rod 10 drives the movable plate 15 to move to the right through the connecting block 14. The movable plate 15 drives the first clamping plate 20 to move, and the sheet metal is further clamped by the first clamping plate 20 and the third clamping plate 22, thereby completing the positioning and fixing of the sheet metal.

[0039] When the sheet metal part needs to be loosened, the cylinder 3 drives the U-shaped push rod 4 to retract, and the U-shaped push rod 4 pushes the push rod 10 to reset;

[0040] For the above structure and process, please refer to Figure 1-5 .

[0041] When clamping sheet metal parts of different sizes, the fixing screws on the bottom plate 2001 are loosened, and the length of the adjustment plate 2002 can be adjusted, so that the sheet metal parts of different sizes can be fixed, thereby improving the application range of the clamping device;

[0042] For the above structure and process, please refer to Figure 5-8 .

[0043] After clamping, when the angle of the sheet metal needs to be adjusted, the motor 503 is started, and the motor 503 drives the gear 505 to rotate through the output shaft 504, and the gear 505 drives the outer ring of the slewing support 502 to rotate, and the slewing support 502 drives the sheet metal placed above to rotate through the mounting frame 1, thereby adjusting the angle of the sheet metal, making it convenient for external equipment to process the sheet metal.
