A clamping mechanism is arranged between the arc-shaped clamping plate 7 and the operating table 1, and the clamping mechanism is used to clamp and fix the flange 2 in the drilling positioning port 20.

A cleaning component is arranged on the lower side of the operating table 1, and the cleaning component is used to clean the waste chips of the flange 2 when drilling.

[0038] In this embodiment, when drilling a hole in the flange 2, the flange 2 is first placed on the sliding plate 4. Since the sliding plate 4 has a certain inclination angle, the sliding plate 4 will cause the flange 2 to slide into the pushing groove 3 and correspond to the pushing plate 6. The pushing mechanism pushes the pushing plate 6 to move, and the pushing plate 6 pushes the flange 2 to move through the elastic component. The pushing component moves the flange 2 into the drilling positioning port 20 and closes the drilling positioning port 20, so that the flange 2 corresponds to the arc-shaped clamping plate 7 and the clamping ring 8. Then the pushing component will push the pushing plate 6 to continue moving, and the pushing plate 6 is positioned by the elastic component. The plate 5 fixes the flange 2 in the drilling positioning opening 20, the arc-shaped clamping plate 7 clamps and fixes the flange 2 through the clamping mechanism, and the clamping ring 8 presses and fixes the flange 2 in the drilling positioning opening 20. The fixed flange 2 is drilled in the drilling positioning opening 20, and the waste chips generated by the drilling will fall from the drilling positioning opening 20.

[0039] Specifically, the pushing mechanism includes a pushing cylinder 601, which is fixedly connected to the operating table 1. The pushing cylinder 601 is electrically connected to an external power supply, and the output end of the pushing cylinder 601 is fixedly connected to the pushing plate 6.

[0040] In this embodiment, the pushing cylinder 601 is started by an external power supply, and the pushing cylinder 601 can push and pull the pushing plate 6. When the pushing cylinder 601 pushes the pushing plate 6, the pushing plate 6 pushes the flange 2 through the elastic component, so that the flange 2 moves into the drilling positioning port 20. At the same time, the pushing plate 6 will drive the slide 602 to slide in the slide 602, and the slider 603 moves the slide plate 604. The slide plate 604 can move to the lower side of the drilling positioning port 20. The flange 2 will be located on the slide plate 604 when it is pushed into the drilling positioning port 20. The slide plate 604 supports the flange 2 so that the flange 2 is drilled in the drilling positioning port 20. After the drilling is completed, the pushing cylinder 601 drives the pushing plate 6 to reset, and the slide plate 604 is also retracted, so that the flange 2 falls out of the drilling positioning port 20 and is discharged.

[0041] Specifically, the clamping mechanism includes two first racks 701, and the two first racks 701 are slidably connected to the lower side of the operating table 1. One end of the two first racks 701 is fixedly connected to a connecting bar 702, and the arc-shaped clamping plate 7 is fixedly connected to the connecting bar 702. The bottom end of the operating table 1 is rotatably connected to two first gears 703, and the two first gears 703 are respectively meshed with the two first racks 701. A driving rack 704 is fixedly connected to the slide plate 604, and the driving rack 704 is meshed with the two first gears 703.

[0042] In this embodiment, when the push plate 6 is pushed, the push plate 6 drives the slide plate 604 to move through the slider 603, and the slide plate 604 drives the driving rack 704 to move. The driving rack 704 causes the two first gears 703 to rotate, and the two first gears 703 cause the two driving racks 704 to move. The two driving racks 704 pull the connecting bar 702 to move, thereby causing the arc-shaped clamping plate 7 to move into the drilling positioning port 20 to clamp and fix the flange 2.

[0043] Specifically, the clamping mechanism includes a second gear 801, which is rotatably connected to the bottom end of the operating table 1, and the second gear 801 is meshed with the driving rack 704. The top of the second gear 801 is fixedly connected with a threaded rod 802, and the threaded rod 802 movably passes through the operating table 1. The outer surface of the threaded rod 802 is threadedly connected with a travel nut 803, and the outer surface of the travel nut 803 is rotatably connected with two rotating sleeves 804. A rotating block 805 is movably hinged on the positioning plate 5 through a hinge shaft, and the clamping ring 8 is fixedly connected to the rotating block 805. Two push rods 806 are fixedly connected to the rotating block 805, and the two push rods 806 are respectively slidably connected in the two rotating sleeves 804.

The two push rods 806 slide in the two rotating sleeves 804 respectively, so that the rotating block 805 rotates on the positioning plate 5, and the clamping ring 8 follows the rotation of the rotating block 805 and presses down to fix the flange 2 in the drilling positioning port 20.

[0045] Specifically, the elastic component includes two sliding rods 901, and the two sliding rods 901 are slidably inserted on the push plate 6. One end of the two sliding rods 901 is fixedly connected to a clamping plate 902. The outer surfaces of the two sliding rods 901 are both sleeved with springs 903, and the two springs 903 are located between the clamping plate 902 and the push plate 6.

[0046] In this embodiment, when the push plate 6 needs to move to push the flange 2, the push plate 6 pushes the flange 2 through the clamping plate 902, so that the flange 2 is pushed into the drilling positioning port 20 and supported by the slide plate 604. The flange 2 will correspond to the clamping ring 8 and the arc-shaped clamping plate 7, and the push plate 6 continues to move, squeezing the two springs 903 on the two sliding rods 901, so that the arc-shaped clamping plate 7 and the clamping ring 8 are in contact with the flange 2 at the same time for fixation. When the push plate 6 is reset, the elastic force of the two springs 903 will reset the clamping plate 902, which is convenient for pushing the flange 2 again.

[0047] Specifically, the cleaning assembly includes a fixed plate 101, which is fixedly connected to the bottom end of the operating table 1, and a fixed rod 102 is fixedly connected to the fixed plate 101. The outer surface of the fixed rod 102 is rotatably connected to a cleaning brush 103, and the cleaning brush 103 corresponds to the slide plate 604.

[0048] In this embodiment, the flange 2 will generate a certain amount of waste chips when drilling, and most of the waste chips will fall through the slide plate 604. When the slide plate 604 is retracted to make the flange 2 fall, some of the remaining waste chips will be scraped off by the operating table 1. At the same time, the driving rack 704 will rotate the third gear 104, and the third gear 104 will rotate the active bevel gear 105. The active bevel gear 105 rotates the cleaning brush 103 on the fixed rod 102 through the driven bevel gear 106, and the cleaning brush 103 cleans the waste chips in the gap of the slide plate 604.

[0050] In this embodiment, the length of the slide plate 4 can be set according to actual conditions, and a conveyor belt can also be connected to transport the flange 2. When the push plate 6 pushes the flange 2, the baffle 11 will close the slide plate 4 to prevent the flange 2 stored on the slide plate 4 from affecting the retraction of the push plate 6. The receiving groove 12 is used to accommodate the baffle 11.

[0051] Specifically, two installation openings 13 are provided on the slide plate 4 , and a group of rollers 14 are rotatably connected in the two installation openings 13 .

[0052] In this embodiment, when the flange 2 slides into the pushing groove 3 through the sliding plate 4, the two groups of rollers 14 provided in the two installation openings 13 can make the flange 2 slide more smoothly.

[0056] In this embodiment, the fixed fastening pad 17 , the arc-shaped fastening pad 18 and the circular fastening pad 19 have a certain anti-slip effect, so that the positioning plate 5 , the arc-shaped clamping plate 7 and the clamping ring 8 maintain good stability when positioning the flange 2 .

[0057] Working principle: by placing the flange 2 in the sliding plate 4, the sliding plate 4 makes the flange 2 slide into the pushing groove 3 and correspond to the top plate 902, and then the pushing cylinder 601 is started by an external power supply, and the pushing cylinder 601 pushes the pushing plate 6 to move, and the pushing plate 6 makes the top plate 902 push the flange 2 to move into the drilling positioning port 20, and at the same time, the pushing plate 6 will drive the slide plate 604 to move through the slider 603, so that the flange 2 is located in the drilling positioning port 20 and is supported by the slide plate 604, and the slide plate 604 moves During the process, the driving rack 704 will be driven to move, and the driving rack 704 will cause the two first gears 703 and the second gear 801 to rotate. The rotation of the two first gears 703 will cause the two first racks 701 to move. The two first racks 701 drive the arc clamping plate 7 to move through the connecting bar 702. The arc clamping plate 7 clamps and fixes the flange 2 in the drilling positioning port 20. The rotation of the second gear 801 can cause the threaded rod 802 to rotate, and the threaded rod 802 can cause the travel nut 803 to move upward, so that The two rotating sleeves 804 push the two pushing rods 806, and the two pushing rods 806 control the rotating block 805 to drive the clamping ring 8 to press and rotate downward, and the clamping ring 8 presses and fixes the flange 2 downward, and finally the flange 2 fixed in the drilling positioning port 20 is drilled by the drilling equipment. After the drilling is completed, a certain amount of waste chips will be generated on the slide plate 604, and the push cylinder 601 controls the push plate 6 to move and reset. At the same time, the slide plate 604 follows the push plate 6 to move to open the drilling positioning port 20. The slide plate 604 moves During the process, the operating table 1 will scrape off the waste chips on the upper side of the slide plate 604, the arc-shaped clamping plate 7 and the clamping ring 8 will move away from the flange 2, and the flange 2 will fall from the drilling positioning port 20 to realize material discharge. While the slide plate 604 follows the reset of the push plate 6, the rack 704 is driven to rotate the third gear 104, and the third gear 104 rotates the driven bevel gear 106 through the active bevel gear 105, and the driven bevel gear 106 controls the cleaning brush 103 to rotate, so that the waste chips in the gap of the slide plate 604 are cleaned.
