At this time, the workpiece is fixed by the upper clamping plate 4 and the lower clamping plate 3. The distance sensor 5 measures the thickness of the workpiece and transmits the measurement result to the controller 6. The controller 6 will determine the punching pressure according to the material and thickness information of the workpiece, and control the punching and polishing mechanism to punch the workpiece according to the judgment result. The waste produced by punching will fall into the collecting mechanism for collection. After the punching is completed, the punching and polishing mechanism will cooperate with the secondary polishing assembly to polish the upper and lower surfaces and the inside of the machining hole. After polishing is completed, the reverse driving device resets each part, and the workpiece processed can be taken off.

[0023] Through the setting, the controller 6 and the distance sensor 5 can be used to measure the thickness of the workpiece, and the optimal punching pressure can be automatically determined according to the material of the workpiece, thereby effectively avoiding uneven punching quality. At the same time, by setting the punching and polishing mechanism and the secondary polishing assembly, the machining hole can be polished directly after punching without replacing the equipment or re-clamping, thereby effectively improving the processing efficiency and processing precision of the equipment and ensuring the safe and stable operation of the wind power hub.

[0025] When punching and polishing are needed, the hydraulic push rod 16 is started, which will push the moving sleeve 15 to drive the mounting seat 17 and the punching column 19 to move downward according to the ideal pressure judged by the controller 6, and punch the workpiece after the lower end of the punching column 19 abuts against the upper surface of the workpiece, and then continue to drive the punching column 19 to move downward through the hydraulic push rod 16, so that the vertical polishing plate 20 slides into the processing hole, and the lower surface of the upper polishing plate 21 abuts against the upper surface of the workpiece, and then the second motor 18 is started, which will drive the mounting seat 17 and the punching column 19 to rotate, so as to polish the inside and the upper of the processing hole through the upper polishing plate 21 and the vertical polishing plate 20, and in this process, the secondary polishing assembly will polish the lower of the processing hole in cooperation with the upper polishing plate 21 and the vertical polishing plate 20.

[0026] Through this setting, the punching column 19, the vertical polishing plate 20 and the upper polishing plate 21 can be used to realize efficient punching and polishing of the workpiece on the same device, avoiding the problems of low efficiency and poor precision caused by punching and polishing on different devices, and the setting of the mounting seat 17 can avoid the direct action of the reverse force of the punching column 19 on the second motor 18 during punching, thereby effectively preventing the second motor 18 from being damaged under pressure, and at the same time, through the setting of the assembly stud 22 and the assembly screw hole, the mounting of the punching column 19 and the mounting seat 17 can be more convenient, so as to quickly replace punching columns 19 of different specifications for processing.

[0027] It should be noted that the rotation direction of the assembly stud 22 when screwed into the assembly screw hole is opposite to the direction of the second motor 18 driving the punching column 19 to rotate and polish, thereby effectively avoiding the punching column 19 from falling off during polishing.

[0029] In the punching process, the punching waste is pushed into the first row of waste holes 26 by the punching column 19, and is discharged into the collecting mechanism through the second row of waste holes 27 under the continuous downward pushing of the punching column 19. In the process of entering the first row of waste holes 26 at the lower end of the punching column 19, the tapered end face of the tapered chuck 29 pushes the tapered chuck 29 to retract into the sliding cavity 28, and compresses the pressure spring 30. After the tapered chuck 29 moves to the position corresponding to the lowermost position of the sliding chuck groove 31, the punching column 19 stops moving downward. At this time, the punching column 19 is driven to rotate for a short time, and the tapered chuck 29 is pushed into the sliding chuck groove 31 by the pressure spring 30 when the position of the tapered chuck 29 corresponds to the sliding chuck groove 31, so that the lower polishing plate 25 and the polishing table 24 can rotate synchronously with the punching column 19. Then the punching column 19 stops rotating and continues to move downward. After the lower surface of the upper polishing plate 21 is attached to the upper surface of the workpiece, the upper polishing plate 21, the lower polishing plate 25 and the vertical polishing plate 20 are driven to rotate synchronously to polish the upper, lower and inner parts of the processed hole. After the polishing is completed, the punching column 19 is driven to reset upward, and the tapered chuck 29 is slid out of the sliding chuck groove 31 through the lower inclined surface of the sliding chuck groove 31, so that the parts of the device are stably reset.

[0030] Through the setting, the upper polishing plate 21, the lower polishing plate 25 and the vertical polishing plate 20 can be used to realize comprehensive polishing of the processed hole, thereby effectively improving the processing quality of the processed hole. Moreover, the polishing table 24 is fixed above the rotating seat 23 by screws, so that different specifications of the polishing table 24 can be conveniently replaced.

[0032] In use, the punching waste falls on the flow guide inclined plate 34 through the first row of waste holes 26 and the second row of waste holes 27, and is collected in the collecting box 33 under the flow guide of the flow guide inclined plate 34.

The mounting plate 36 and the mounting hole 37 can facilitate the installation of the device.

At this time, the workpiece is fixed by the upper clamping plate 4 and the lower clamping plate 3, and the distance sensor 5 measures the thickness of the workpiece and transmits the measurement result to the controller 6. The controller 6 will determine the punching pressure according to the material and thickness information of the workpiece, and control the punching and polishing mechanism to punch the workpiece according to the judgment result. The waste produced by punching will fall into the collecting mechanism for collection. After the punching is completed, the punching and polishing mechanism will cooperate with the secondary polishing assembly to polish the upper and lower surfaces and the inside of the machining hole. After polishing is completed, the reverse driving device resets each part, and the workpiece processed can be taken off.
