[0002] The pad needs to be punched during processing and production. Stamping is a process at room temperature where a die installed on a press is used to apply pressure to the material to cause it to separate or plastically deform.

The clamp 3 is a prior art, so it will not be described in detail; The multi-stage telescopic cylinder 4 starts to work, and the telescopic end of the multi-stage telescopic cylinder 4 contracts to drive the lifting top plate 5 to descend, and the lifting top plate 5 drives the fixed ring 7, the fixed circular plate 8, and the pneumatic grinding part 9 to descend through the fixed bearing 6, so that the pneumatic grinding part 9 moves into the punching hole of the pad, and the pneumatic grinding part 9 is driven to rotate by the adjusting driving part 10, and the fixed ring 7 rotates along the fixed bearing 6, and the burrs on the pad are polished by the pneumatic grinding part 9; During grinding, the dust collection device 13 starts to work, and the debris generated during grinding falls into the waste chip collection box 11 through the processing through hole 2. The dust collection device 13 sucks out the waste chips in the waste chip collection box 11 through the exhaust pipe 12. The dust collection device 13 is a prior art and is not described in detail. The air blowing part 14 is used to blow air to the inflatable grinding part 9 and the pad, and the debris on the inflatable grinding part 9 and the pad is blown toward the processing through hole 2, so that the debris on the inflatable grinding part 9 and the pad falls into the waste chip collection box 11.
[0019] Refer to the instruction manual Figure 2 , Instruction Manual Figure 4 And the instruction manual Figure 5 The inflatable polishing part 9 includes an inflatable airbag 15 fixedly mounted on the bottom of the fixed circular plate 8, a fixed bottom plate 16 is installed at the bottom of the inflatable airbag 15, a fixed through hole 17 is provided at the center of the lifting top plate 5, the center of the fixed through hole 17 is the same as the center of the fixed bearing 6, an inflatable tube 18 is connected at the center of the fixed circular plate 8, the inflatable tube 18 penetrates the fixed circular plate 8 and extends into the inflatable airbag 15, and small air outlet holes 19 are provided around the inflatable tube 18, the small air outlet holes 19 are located in the inflatable airbag 15, the top of the inflatable tube 18 penetrates the fixed through hole 17 and extends out of the lifting top plate 5, a rotary joint 20 is connected to the top of the inflatable tube 18, an inflatable pump 21 is installed on the lifting top plate 5, an inflatable end of the inflatable pump 21 is connected to an inflatable hose 22, and the inflatable hose 22 is fixedly connected to the rotary joint 20 at one end away from the inflatable pump 21, a fixed block 23 is installed at the center of the outer wall of the inflatable airbag 15, and a polishing plate 24 is connected to the fixed block 23.
[0020] Specifically, in practical applications, the inflatable grinding part 9 descends into the punching hole of the backing plate and the grinding plate 24 stops descending when it is located at the center of the punching hole. The inflatable pump 21 starts working, and the gas is delivered to the inflatable tube 18 through the inflatable hose 22 and the rotary joint 20. The gas in the inflatable tube 18 enters the inflatable airbag 15 from the air outlet hole 19. The inflatable airbag 15 is inflated by inflation. The inflatable airbag 15 gradually expands and drives the fixed block 23 and the grinding plate 24 to move, so that the grinding plate 24 and the inner part of the punching hole of the backing plate are in contact with each other. The fixed block 23 and the grinding plate 24 are installed on one side of the inflatable airbag 15. After the grinding plate 24 contacts the inner wall of the punching hole, there is a gap between the outer wall of the inflatable airbag 15 and the inner wall of the punching hole. The inflatable airbag 15 drives the fixed block 23 and the grinding plate 24 to rotate, and the inner wall of the punching hole is polished and deburred by the grinding plate 24. The inflatable airbag 15 applies elastic pressure to the grinding plate 24, so that the grinding plate 24 fits tightly with the inner wall of the punching hole, which can prevent the grinding plate 24 from deviating from the position and improve the grinding efficiency and effect.
[0021] Refer to the instruction manual Figure 3 , Instruction Manual Figure 4 , Instruction Manual Figure 6 And the instruction manual Figure 7 The adjustment drive unit 10 includes a sealed bearing 25 arranged at the center of the bottom wall of the waste collection box 11, and the inner ring of the sealed bearing 25 is slidably connected to the driving shaft 26. A driving cylinder 27 is installed on one side of the bottom of the processing platform 1, and a motor seat 28 is installed on the telescopic end of the driving cylinder 27. A driving motor 29 is installed on the motor seat 28. The output end of the driving motor 29 is fixedly connected to the bottom end of the driving shaft 26, and a connecting shaft 30 is installed at the top of the driving shaft 26. Vertical steel bars 31 are installed on both sides of the connecting shaft 30. A fixed sleeve 32 is installed at the center of the bottom of the fixed base plate 16, and vertical grooves 33 are provided on both sides of the inner wall of the fixed sleeve 32, and the vertical steel bars 31 are consistent with the vertical grooves 33.
[0022] Specifically in practical applications, after the pneumatic grinding part 9 is lowered into place, the driving cylinder 27 starts to work, the telescopic end of the driving cylinder 27 contracts to drive the motor seat 28 to rise, and the motor seat 28 drives the driving motor 29, the driving shaft 26 and the connecting shaft 30 to rise, the driving shaft 26 moves along the inner ring of the sealed bearing 25, and the connecting shaft 30 drives the vertical steel bar 31 to move upward, so that the connecting shaft 30 is inserted into the fixed sleeve 32, and the vertical steel bar 31 is inserted into the vertical groove 33, the driving motor 29 starts to work, and the output end of the driving motor 29 drives the driving shaft 26 to rotate, and the driving shaft 26 drives the fixed sleeve through the connecting shaft 30. The cylinder 32 rotates, and the fixed sleeve 32 drives the inflatable airbag 15 to rotate through the fixed base plate 16, which is convenient for docking and convenient for driving the inflatable grinding part 9 to rotate for grinding. When the punching of the pad is large and the inflatable airbag 15 cannot contact the inner wall of the punching of the pad after inflation, the multi-stage telescopic cylinder 4 and the driving cylinder 27 shrink at the same time, and the inflatable airbag 15 is squeezed through the fixed circular plate 8 and the fixed base plate 16, so that the middle part of the inflatable airbag 15 bulges outward, so that the grinding plate 24 contacts the inner wall of the punching. It is suitable for punching pads of different sizes and specifications, which improves applicability and does not require replacement of grinding tools, thereby improving work efficiency.
[0023] Refer to the instruction manual Figure 2 , Instruction Manual Figure 3 And the instruction manual Figure 4 The blowing part 14 includes a plurality of articulated frames 34 installed around the bottom of the fixed circular plate 8, and the plurality of articulated frames 34 are distributed around the inflatable airbag 15.

An electric slip ring 40 is mounted on the inflatable pipe 18, and the electric slip ring 40 is located below the rotary joint 20.
[0024] Specifically in practical applications, when the inflatable airbag 15 is inflated, the gas can pass through the one-way valve 39, and the gas cannot flow in the reverse direction. After the grinding is completed, the exhaust valve 38 is opened, and the gas in the inflatable airbag 15 enters the inflatable tube 18 through the air outlet hole 19. The gas entering the inflatable tube 18 enters the air supply hose 37. The gas in the inflatable airbag 15 enters the exhaust valve 38 through the inflatable tube 18 and the air supply hose 37. The air nozzles 35 are connected to each other through the connecting hose 36. The nozzle 35 discharges the gas in the inflatable airbag 15, and the jet nozzle 35 blows the gas toward the inflatable airbag 15 and the pad, so that the waste gas can be utilized to avoid waste. The air is blown so that the debris on the inflatable airbag 15 and the pad is blown toward the processed through hole 2, and the debris falls into the waste collection box 11 through the processed through hole 2. The dust suction device 13 sucks out the waste in the waste collection box 11 through the exhaust pipe 12 and collects the debris, and cleans the debris on the pad to avoid the staff from being stabbed by the debris when taking and placing the pad, thereby improving safety.

A rectangular block 42 is fixedly connected to the bottom of the inflation tube 18, and the rectangular block 42 extends into the square sleeve 41 and is slidably connected to the square sleeve 41.
[0026] Specifically in actual applications, when the inflatable airbag 15 is squeezed, the rectangular block 42 at the bottom of the inflation tube 18 slides along the inner wall of the square sleeve 41. During rotation, the square sleeve 41, the rectangular block 42 and the inflation tube 18 improve the stability of the inflatable airbag 15 and prevent the inflatable airbag 15 from deformation.

[0028] Specifically in actual application, when the motor seat 28 is lifted and slid, the motor seat 28 is lifted and lowered along the guide rod 43. The guide rod 43 guides the motor seat 28 to prevent the motor seat 28 from tilting and displacing. The limit block 44 limits the motor seat 28 to the minimum position.
