[0033] refer to Figure 1 and Figure 6-7 The feeding mechanism 3 includes a silo 31 and a feeding rod 33. The silo 31 is installed on the upper side of the base frame 11. The silo 31 is used to place the flange to be processed. A gap is provided between the silo 31 and the base frame 11, which allows only one flange to pass through. The gap is adjustable and can be adjusted according to the thickness of flanges of different specifications. A feeding rod 33 is provided at the bottom of the silo 31. The feeding rod 33 is slidably connected to the base frame 11. The running trajectory of the feeding rod 33 passes through the gap between the silo 31 and the base frame 11. The feeding rod 33 is driven by a second cylinder 32. The second cylinder 32 is fixedly installed on the upper side of the base frame 11. The piston rod of the second cylinder 32 is fixedly connected to the feeding rod 33. When the feeding rod 33 moves, a flange at the bottom of the silo 31 can be pushed to the processing area so that it is located directly above the circular hole 12 between the left clamp 13 and the right clamp 14, thereby realizing feeding. The material return mechanism 4 includes a material return push block 42 and a third cylinder 41. The material return push block 42 is slidably connected to the base frame 11. The material return push block 42 is driven by the third cylinder 41. The third cylinder 41 is fixedly arranged at the bottom of the base frame 11. The piston rod of the third cylinder 41 is fixedly connected to the material return push block 42. The processed flange is pushed away from the processing area on the base frame 11 through the material return mechanism 4.

[0034] Working principle: First, the flange to be processed is transported to the processing area on the chassis 11, that is, between the left fixture 13 and the right fixture 14, through the feeding mechanism 3, and then the first cylinder 23 is started to drive the carrier 26 to move downward. At this time, the positioning mechanism 6 will pass through the center hole of the flange and position it. At the same time, the pre-tightening mechanism 5 will press the flange, and the drilling machine 27 will be started. The piston rod of the first cylinder 23 continues to move slowly downward, driving the drilling machine 27 to process the hole. After processing a hole, the piston rod of the first cylinder 23 slowly rises upward and rotates a certain angle. For example, if four holes are processed, it rotates 90 degrees. During the rotation process, the pre-tightening mechanism 5 is still pressing the flange, and the cone 62 and the fixed rod 61 rotate relative to each other. This cycle is repeated until the processing is completed. The piston rod of the first cylinder 23 is completely retracted upward, and the flange is out of contact with the drilling machine 27, the pre-tightening mechanism 5, etc., and then the material removal mechanism 4 pushes it away from the processing area. This device saves labor costs and improves processing efficiency through automated processing, and has a good market prospect.
