By measuring the distance to various points on the hole wall during rotation using a distance sensor embedded in the ring, it can immediately determine whether there are protrusions or depressions on the inner wall of the hole, and whether the hole diameter is uniform. The electric push rod achieves rapid installation and disassembly via an electromagnet. When collecting the finished product, the entire inner support assembly can be lifted directly by an external robotic arm. At this time, the force plate still supports a set of flanges, clamping the entire assembly with the flanges and moving it outwards, which is convenient, efficient, and safe.

Specifically, each of the four corners of the rotating disk 9 can be equipped with a placement component 11 to form a "four-station" rotary table. When drilling is being performed at one station, the operator can simultaneously perform loading and unloading operations at other stations, greatly reducing equipment waiting time. After drilling is completed, the flange is transferred to another area, and then the flange slides down to the monitoring component 1147 below for processing.

A permanent magnet is provided at the bottom of the electric push rod 11151. An electromagnet is provided in the connection area between the inner frame 113 and the permanent magnet. By energizing the electromagnet and attracting the permanent magnet, the electric push rod 11151 can be fixedly installed, which is convenient for subsequent disassembly.

[0027] Please see Figures 3-6 and Figures 9-11 A stepper motor 1141 is bolted to the upper side wall of the inner frame 113. The stepper motor 1141 drives the transmission gear 1143 to rotate and connect with the upper end of the inner frame 113 through the first worm gear 1142.

Among them, the upper end of the drive rod 11471 is fixedly connected to the upper rod 11473, and the side wall of the upper rod 11473 is embedded with an embedded ring 11474.

The sliding rod 11477 slides through the inner side wall of the upper rod 11473 and extends outward. A grinding rod 11478 is fixedly connected to the side wall of the sliding rod 11477. Specifically, the grinding rod 11478 has multiple grinding areas from top to bottom, and the surface roughness of the multiple grinding areas is different.

[0029] The working principle of a drilling device for metal flange processing is as follows: First, when using this device, place it in the work area, and then connect it to an external power source to provide the power required for its operation. During processing, the flange to be processed is placed between multiple sets of contact frames 1112. The auxiliary motor 117 is started to drive the drive gear 118 to rotate. The drive gear 118 drives the second gear ring 119 to rotate. The second gear ring 119 drives multiple sets of driven gears 1110 to rotate. The driven gears 1110 are meshed and driven to rotate. The multiple sets of driven gears 1110 drive multiple sets of contact frames 1112 to rotate inward. After the contact frames 1112 rotate inward, the bottom of the multiple sets of contact frames 1112 contacts multiple positions on the bottom of the flange. The electromagnetic spring 1113 is activated to push the contact plate 1114 to move downward. The contact plate 1114 moves downward until it is pressed and fixed to the flange surface, so that the flange is fixed on the contact frame 1112. Second, the electric push rod 11151 is controlled to drive the limiting frame 11152 to move upward. The limiting frame 11152 drives multiple sets of force plates 11157 to move upward. The multiple sets of force plates 11157 move upward and slide into the cavity of the central area of ​​the flange. Then, the receiving motor 11159 is controlled to drive the auxiliary gear 11158 to rotate. The auxiliary gear 11158 drives the drive gear 11153 to rotate. The drive gear 11153 drives the force rod 11155 to move through the connecting groove 11154. The force rod 11155 drives the second guide rod 11156 to move. The multiple sets of second guide rods 11156 drive the force plates 11157 to move outward. The multiple sets of force plates 11157 move outward until they are pressed and fixed to the surface of the central cavity inside the flange, so that the multiple sets of force plates 11157 apply extrusion force to different radial directions of the flange. The hydraulic cylinder 5 controls the drive motor 6 and drill bit 7 to move downwards, and the drill bit 7 can also drill holes in the flange below; Third, control the servo motor 112 to drive the inner frame 113 to rotate, and the inner frame 113 to drive the upper flange to rotate and adjust its position, so that the drill bit 7 drills holes at different positions of the flange, and a monitoring component 1147 is provided below the bolt hole after the flange drilling is completed. Fourth, after drilling is completed, the auxiliary motor 117 drives the drive gear 118 to reverse, and the drive gear 118 drives the contact frame 1112 to reverse, so that the contact frame 1112 and the flange disappear, and the force plate 11157 is pressed and fixed to the inner diameter surface of the flange, so that the flange will not fall down. Then, the multiple sets of force plates 11157 are controlled to move slightly inward, so that the pressure of the force plate 11157 on the inner diameter of the flange is reduced. Due to the influence of gravity, the flange will slide down, and the bolt holes on the flange after drilling are slid into the outer end of the upper rod 11473 (or the flange is moved down by the electric push rod 11151). The control and adjustment motor 11475 drives the second worm gear 11476 to rotate, the second worm gear 11476 drives the double screw to rotate, the double screw drives the sliding rod 11477 to move, so that the two sets of sliding rods 11477 drive the grinding rod 11478 to move, and the distance between the two sets of grinding rods 11478 can be adjusted, thereby adjusting the grinding diameter formed when the grinding rod 11478 rotates, which is convenient to adapt to the bolt holes of different flanges; Fourth, when the flange slides down to the first grinding area at the upper end of the grinding rod 11478, the force plate 11157 is controlled to move outward to press and fix the flange, so that the flange stops moving downward (or the flange is driven to move downward by the electric push rod 11151). Then, multiple grinding motors 11472 are controlled to drive the drive rod 11471 and the upper rod 11473 to rotate. The upper rod 11473 drives the grinding rod 11478 to rotate, and the first grinding area on the grinding rod 11478 grinds the surface of the bolt holes of the flange. The force plate 11157 moves inward, and the flange moves downward until it is at the same height as the second grinding area on the grinding rod 11478. The force plate 11157 moves outward and presses and fixes the flange (or drives the flange to move downward through the electric push rod 11151). The motor 11472 indirectly passes through the second grinding area on the grinding rod 11478 and grinds the surface of the bolt holes of the flange, and this cycle is repeated. The force plate 11157 moves inward, the flange moves downward into the area of ​​the embedded ring 11474, the force plate 11157 moves outward and is pressed and fixed with the flange (or the flange is moved downward by the electric push rod 11151), the grinding motor 11472 drives the upper rod 11473 and the embedded ring 11474 to rotate, the embedded ring 11474 drives the distance sensor to rotate, so that the embedded ring 11474 and the bolt hole are in the same circle. The distance sensor monitors the distance between the embedded ring and the inner surface of the flange bolt hole, and uses this to monitor whether the inner wall of the bolt hole is flat. The force plate 11157 is moved inward, and the flange slides downward to the area above the drive plate 1145 to collect the processed flanges. When a number of flanges are collected on the drive plate 1145, the bottom of the electric push rod 11151 is disassembled from the inner frame 113. At the same time, the force plate 11157 is pressed into contact with the inner wall of multiple flanges, and force is applied to lift the force plate 11157 upward. The multiple force plates 11157 are pressed and fixed with the inner diameter of the flanges, so that the inner support assembly 1115 drives the multiple flanges to move outward to the outer end, which facilitates the transfer of multiple flanges.
