[0024] See also Figure 1-6, a drilling device for flange production, including a base 1 and a drilling manipulator 2 installed on the base 1, a circular workbench 3 is provided on the base 1 on one side of the drilling manipulator 2, the drilling manipulator 2 can drive the drill bit to move above the circular workbench 3, and a support plate 4 is fixedly connected to the middle position below the circular workbench 3 through a suspension rod, and a plurality of groups of screws 5 are rotatably connected to the support plate 4, each group of screws 5 is oriented toward the center of the circular workbench 3, and a threaded sleeve 6 is threaded on the surface of each group of screws 5. When the screw 5 rotates relative to the threaded sleeve 6, the screw 5 can drive the threaded sleeve 6 to move along its surface toward or away from the center of the support plate 4, and a connecting rod 7 is fixedly connected to the threaded sleeve 6. The top of the circular workbench 3 is provided with several groups of through slits 8. The top of each group of connecting rods 7 passes through the through slits 8 and extends above the circular workbench 3 and is fixedly connected to an L-shaped clamping plate 9 for clamping and fixing the flange placed above the circular workbench 3. Each group of L-shaped clamping plates 9 is facing the center of the circular workbench 3 and has the same height. A cylinder 10 is provided inside the circular workbench 3 just below the support plate 4. One end of the output shaft of the cylinder 10 is fixedly connected to an annular frame 11. A driving assembly is provided between the annular frame 11 and the several groups of screw rods 5. When the output shaft of the cylinder 10 drives the annular frame 11 to move upward or downward, the annular frame 11 can drive the several groups of screw rods 5 to rotate synchronously through the driving assembly.

[0025] When in use, by starting the cylinder 10, the output shaft of the cylinder 10 can drive the annular frame 11 to move upward or downward. During this process, the annular frame 11 will drive several groups of screws 5 to rotate synchronously in the forward or reverse direction through the driving assembly, and several groups of screw sleeves 6 will synchronously approach or move away from the center of the circular workbench 3 in the direction of the center of the circular workbench 3 under the driving action of the screw 5. During this process, several groups of screw sleeves 6 will drive the L-shaped splints 9 located above the circular workbench 3 to synchronously approach or move away from the center of the circular workbench 3 through the connecting rod 7. Therefore, when the flange is placed above the circular workbench 3, it can be controlled to synchronously approach the center of the circular workbench 3 by controlling several groups of L-shaped splints 9. At this time, the side plates of several groups of L-shaped splints 9 are The side wall contact of the flange can clamp the flange and fix it in the center position above the circular workbench 3. At the same time, the bottom plate of the L-shaped clamp 9 contacts the bottom periphery of the flange, which can provide stable support for the bottom periphery of the flange. When the drilling robot 2 drives the drill bit to drill the flange on the circular workbench 3, the flange can be maintained in the center position above the circular workbench 3 without displacement. It can be seen that the user only needs to control the output shaft of the cylinder 10 to drive the annular frame 11 to move up or down, and can control several groups of L-shaped clamps 9 to synchronously approach or move away from the center of the circular workbench 3, thereby clamping flanges of different diameters and fixing them in the center position of the circular workbench 3, thereby realizing the function of processing flanges of different diameter specifications, and effectively improving the applicability of the device.

[0026] For further information, see Figure 4-6 The driving assembly includes a gear 12 fixedly sleeved on the end of several groups of screw rods 5, and several groups of racks 13 fixedly connected to the edge of the annular frame 11 and meshing with several groups of gears 12. When the annular frame 11 moves up or down, it will drive several groups of racks 13 on its edge to move up or down synchronously. At this time, the gear 12 will drive several groups of screw rods 5 to rotate forward or reverse synchronously under the synchronous driving action of several groups of racks 13.

[0027] For further information, see Figure 4 A support seat 14 is provided in the middle position of the circular workbench 3. The height of the support seat 14 is the same as the bottom plate height of the L-shaped clamping plate 9. It can support the middle part of the flange, so that people can easily place the flange on top of the circular workbench 3 before clamping the flange.

[0028] For further information, see Figure 1 and Figure 2 A baffle 15 is provided around the circular workbench 3. During the drilling process, the baffle 15 can prevent the generated debris from splashing around and causing harm to the surrounding personnel. A sliding door 16 is installed on the baffle 15. After opening the sliding door 16, the flange on the circular workbench 3 can be taken and placed.

[0029] For further information, see Figure 2 A lighting lamp 17 is installed on the top of the baffle 15. When the environment around the workplace is relatively dim, turning on the lighting lamp 17 can illuminate the top of the circular workbench 3. A transparent observation window 18 is provided on the side wall of the baffle 15, which is convenient for people to observe the flange processing process from the outside of the baffle 15.

[0030] For further information, see Figure 1 , a 20 is provided on the circular workbench 3 to facilitate the staff to overhaul and maintain the cylinder 10 inside the circular workbench 3.

[0031] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
