The outer wall of the clamping plate 21 is fixedly provided with a first anti-slip pad 22. The valve 25 is opened, and then the high-pressure air pump 26 delivers high-pressure gas to the cylinder 2 through the valve 25, the shunt pipe 24 and the air pipe 23, so as to drive the cylinder 2 to drive the clamping plate 21 to move. The top of the output end of the servo motor 261 is fixedly provided with a first bevel gear 27. The outer wall of the first bevel gear 27 is evenly meshed. A second bevel gear 29 is combined, and a screw 28 is fixedly provided on the outer side wall of the second bevel gear 29. An internal threaded slide plate 291 is screwed on the outer side wall of the screw 28. A second anti-slip pad 292 is fixedly provided on the outer side wall of the internal threaded slide plate 291. The first bevel gear 27 is driven to rotate by the servo motor 261, and the second bevel gear 29 is driven to rotate by the first bevel gear 27, and the screw 28 is driven to rotate by the second bevel gear 29. The internal threaded slide plate 291 is driven to move outward by the screw 28. The threads on the outer surfaces of each two sets of relatively installed screws 28 are designed in opposite ways. When each relatively installed screw 28 rotates, the internal threaded slide plate 291 on its outer side will be driven to move outward synchronously. An inverted V-groove is provided through the outer side wall of the internal threaded slide plate 291.

[0031] The collecting assembly 300 includes a material guide rack 3 and an inverted V-plate 32. A storage box 31 is placed below the material guide rack 3.

The inverted V-plate 32 is located above the feed port of the material guide rack 3.

[0032] The cylinder 2 is evenly fixed on the top of the workbench 1, the high-pressure air pump 26 is fixed on the bottom of the inner wall of the support frame 11, the servo motor 261 is fixed on the bottom of the workbench 1, and the first bevel gear 27 and the second bevel gear 29 are both rotatably set in the mounting groove of the workbench 1.

[0033] The screw 28 is rotatably set in the slide groove of the workbench 1, and the screw 28 passes through the mounting groove of the workbench 1 and is connected to the second bevel gear 29. The internal thread slide plate 291 is slidably set in the slide groove of the workbench 1.

[0034] The inverted V-plate 32 is fixedly arranged in the slide groove of the workbench 1, and the sealing gasket 33 is fixedly arranged in the inverted V-groove of the internal threaded slide plate 291. The inverted V-plate 32 is located above the screw 28. The screw 28 can be protected by the inverted V-plate 32 to prevent debris from contacting the screw 28, thereby ensuring the reliability of the screw connection between the screw 28 and the internal threaded slide plate 291, and then ensuring the reliability of the device. When the screw 28 drives the internal threaded slide plate 291 to move, it will drive the sealing gasket 33 to move synchronously. When the sealing gasket 33 moves, it will scrape off the debris attached to the surface of the inverted V-plate 32.

[0035] The guide rack 3 is evenly fixed at the bottom of the workbench 1, the guide rack 3 is connected to the slide groove of the workbench 1, and the storage box 31 is evenly placed at the bottom of the inner wall of the support frame 11. The debris generated by the processing of the thin-walled parts 4 and the debris scraped off the surface of the inverted V-plate 32 by the sealing gasket 33 will fall down along the surface of the inverted V-plate 32 into the guide rack 3, and fall into the storage box 31 through the guide rack 3, so that the debris collection and recovery work can be quickly completed.

[0036] The thin-walled member 4 is placed on the top of the workbench 1 , and the thin-walled member 4 is located between the first anti-slip pad 22 and the second anti-slip pad 292 .

[0037] The first anti-skid pads 22 are evenly distributed on the outer circle of the thin-walled part 4 in an annular array, and the second anti-skid pads 292 are evenly distributed on the inner circle of the thin-walled part 4 in an annular array.

[0038] A method for using a clamping device for processing aviation thin-walled parts:

[0039] Step 1: Place the thin-walled part 4 on the top of the workbench 1, and make the thin-walled part 4 between the second anti-slip pad 292 and the first anti-slip pad 22, drive the first bevel gear 27 to rotate through the servo motor 261, drive the second bevel gear 29 to rotate through the first bevel gear 27, drive the screw 28 to rotate through the second bevel gear 29, drive the internal thread slide 291 to move outward through the screw 28, and drive the second anti-slip pad 292 to press against the inner wall of the thin-walled part 4 through the internal thread slide 291. The outer threads of each two sets of relatively installed screws 28 are designed in opposite ways, so that when each two sets of relatively installed screws 28 rotate, the inner thread slide 291 on the outer side thereof will be driven to move outward synchronously.

[0040] Step 2: Open the valve 25, and then the high-pressure air pump 26 delivers high-pressure gas into the cylinder 2 through the valve 25, the shunt pipe 24 and the air pipe 23, so as to drive the cylinder 2 to drive the clamping plate 21 to move, and drive the first anti-skid pad 22 to press against the outer wall of the thin-walled part 4 through the clamping plate 21. Then, after closing the valve 25, the high-pressure air pump 26 can be turned off to complete the locking of the cylinder 2, and the outer wall and inner wall of the thin-walled part 4 are clamped in the same position by the clamping plate 21 and the internal threaded slide plate 291, so as to prevent the thin-walled part 4 from being deformed due to excessive force on one side, and the first anti-skid pad 22 and the second anti-skid pad 292 can prevent the clamping plate 21 and the internal threaded slide plate 291 from causing wear to the thin-walled part 4 during the clamping process.

[0041] Step three: When the thin-walled part 4 is being processed, some of the debris generated during the processing will fall into the slide groove of the workbench 1. The screw 28 can be protected by the inverted V-plate 32 to prevent the debris from contacting the screw 28, thereby ensuring the reliability of the screw connection between the screw 28 and the internal threaded slide plate 291, and further ensuring the reliability of the device. When the screw 28 drives the internal threaded slide plate 291 to move, it will drive the sealing gasket 33 to move synchronously. When the sealing gasket 33 moves, it will scrape off the debris attached to the surface of the inverted V-plate 32. The debris generated by the processing of the thin-walled part 4 and the debris scraped off the surface of the inverted V-plate 32 by the sealing gasket 33 will fall downward along the surface of the inverted V-plate 32 into the guide rack 3, and fall into the storage box 31 through the guide rack 3, so that the debris collection and recovery work can be quickly completed.
