The bottom end of the output shaft of motor 2 15 is fixedly connected to gear 17, and four gears 2 18 are evenly distributed around the outside of gear 17. Gear 2 18 is rotatably connected to the fixed disk 16, and gear 2 18 is engaged with gear 17. A drill bit 19 is vertically fixedly connected to the bottom center of gear 2 18.

[0019] The double-station clamping mechanism includes two fixed rods 3 symmetrically distributed on the left and right sides. The fixed rods 3 are fixedly connected between the front and rear inner walls of the opening 20. The upper part of the support frame 1 is the opening 20. A bidirectional screw rod 4 is rotatably connected between the middle parts of the two fixed rods 3. The two ends of the bidirectional screw rod 4 respectively pass through the middle parts of the two fixed rods 3. A motor 5 is fixedly installed on the left wall of the left fixed rod 3. The output shaft of the motor 5 is fixedly connected to the left end of the bidirectional screw rod 4. A slide groove 6 is provided on the front and rear inner walls of the opening 20. There are two symmetrical movable plates 7 in the opening 20. The front and rear sides of the movable plate 7 are connected to the movable plate 7. The walls are rotatably connected with a pulley 8, the pulley 8 is in the slide groove 6, the pulley 8 and the slide groove 6 are slidably engaged, the bottom of the movable plate 7 is fixedly connected to the fixed plate 21, the bidirectional screw 4 passes through the fixed plate 21, the bidirectional screw 4 is threadedly engaged with the fixed plate 21, the top of the movable plate 7 is fixedly connected to a clamping platform 9, the top of the clamping platform 9 is fixedly connected to three fixed seats 10, the three fixed seats 10 are distributed in an equilateral triangle, the clamping screw 11 passes through the fixed seat 10, the fixed seat 10 is threadedly connected to the clamping screw 11, the ends of the three clamping screws 11 are all facing the center of the clamping platform 9, and the clamping platform 9 is circular.

[0020] The fixed plate 16 is located above the clamping platform 9 , and the two fixed plates 16 correspond to the positions of the two clamping platforms 9 above and below.

[0021] The belt conveyor 2 is a conventional device and its specific structure will not be described in detail.

[0022] The flange to be processed is placed on the clamping table 9 of the double-station clamping mechanism. Three fixed seats 10 distributed in an equilateral triangle are provided on the top of each clamping table 9. By rotating the clamping screw 11, the end of the screw is directed toward and in close contact with the edge of the flange, so that the flange can be firmly clamped.

[0023] After the flange is clamped, the cylinder 14 is started to lower the motor 2 15 and the gear 1 17 and four gear 2 18 fixed thereunder (a drill bit 19 is connected to the bottom of each gear 2 18) to a suitable height until the drill bit 19 contacts the flange surface. At this time, the motor 2 15 starts working and drives the gear 1 17 to rotate. Since the gear 17 is meshed with the four gear 2 18, synchronous rotation is achieved, driving the four drill bits 19 to drill the flange at the same time, which greatly improves the processing efficiency and reduces the processing time.

[0024] After the drilling is completed, the cylinder 14 is lifted to make the drill bit 19 leave the flange. Then, the motor 5 is started, and the motor 5 drives the bidirectional screw 4 to rotate. Since the movable plate 7 is threaded with the bidirectional screw 4, and pulleys 8 are provided on both sides to slide in the slide 6 to ensure smooth movement, the two movable plates 7 will move to both sides at the same time to release the processed flange. At this time, the worker can remove the processed flange and transport it to the next process through the belt conveyor 2.

[0025] After the movable plate 7 is moved away, the new flange to be processed is quickly placed on the clamping table 9 and the clamping operation is repeated. The motor 1 5 then drives the bidirectional screw 4 to rotate in the opposite direction, causing the two movable plates 7 to simultaneously move toward the center. After that, the cylinder 14 and motor 2 15 are started again to perform a new round of drilling. This process can be repeated to achieve continuous and efficient flange processing. This utility model only protects the mechanical part. The related functions realized by the software control part are not within the scope of protection of this utility model.
