[0013] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0014] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further. Example

[0015] Please see Figure 1-2 In the mechanized production of flanges, drilling is a crucial process. Traditional flange drilling equipment typically suffers from several technical bottlenecks that hinder further improvements in production efficiency and processing quality: First, the adaptability is poor and adjustments are cumbersome. Existing fixtures are mostly of fixed dimensions or require manual replacement of fixture components, making it difficult to quickly adapt to flange workpieces of different diameters and thicknesses. Each time product specifications are changed, the machine must be stopped and complex mechanical adjustments performed, severely impacting the continuity and automation of the production line, increasing the workload of operators and production costs.

[0016] Secondly, the fixing effect is limited. Conventional clamps mostly use mechanical clamping in one direction (such as clamping only from the side or only from the top). During high-speed drilling operations, especially for large or irregularly shaped flanges, the workpiece is prone to slight displacement or vibration. This problem of "under-positioning" or "under-constraint" will lead to a decrease in drilling accuracy, hole position deviation, or even drill bit breakage, affecting product quality and creating safety hazards.

[0017] Secondly, there is a lack of precise angle adjustment capabilities. Many existing machines have fixed worktables or can only perform simple indexing. When it is necessary to machine non-standard angled hole systems on flanges, or to make minor corrections to the workpiece posture to compensate for errors in previous processes, existing machines are often powerless, limiting their flexibility in processing complex products. Therefore, this application protects a drilling device for flange production. The flange is stably transported by a roller conveyor. A handling robotic arm on the processing support 3 drives a hydraulic chuck, which moves the flange onto the processing table 1. An angle-level fine-tuning drive 19 inside the annular drive groove 87 rotates, causing a bevel drive gear 18 on its drive end to rotate. The bevel drive gear 18 then drives a fine-tuning bevel gear 20 meshing with it, which in turn rotates. This, in turn, drives a convex annular slider 15 on a bevel annular rack 16, causing the convex annular slider 15 to move along the inner side of a concave annular slide rail 14. To achieve stable horizontal rotation, the convex annular slider 15 drives the conical annular rack 16 on it, which in turn drives multiple bevel gears 13 meshing with it. The bevel gears 13 drive the drive transmission shaft 5, which in turn drives the horizontal gear set 12. The horizontal gear set 12 drives a pair of horizontal adjusting threaded rods 9, which in turn drive a pair of horizontal adjusting threaded tubes. These tubes extend and retract horizontally along the horizontal adjusting threaded rods 9, thereby driving the... The horizontal L-shaped adjusting blocks 10, consisting of three pairs, clamp the flange, allowing for the clamping and fixing of flanges of different sizes according to different needs. By energizing the loop-shaped electromagnets on the pair of loop-shaped magnetic adjusting blocks inside the loop-shaped lifting limit blocks 11 on the horizontal L-shaped adjusting blocks 10, different magnetic fields and forces are generated by changing the current magnitude and direction. This magnetically raises and lowers the loop-shaped magnets on the loop-shaped pressing blocks, thus vertically raising, lowering, pressing, and clamping the flange. The inner side of the fine-tuning shaft barrel 23 on the horizontal adjusting disc 2... The negative pressure electric push rod 25 extends and retracts, driving the negative pressure disc 26 on the push end of the negative pressure electric push rod 25. The negative pressure disc 26 drives the negative pressure ring 27 on it. The negative pressure ring 27 and the negative pressure disc 26 work together to raise and lower, thereby generating negative pressure. This negative pressure is used to fix the original flange by adsorption. The negative pressure regulating drive motor runs, driving the negative pressure bevel gear 13 on the drive end of the negative pressure regulating drive motor. The negative pressure bevel gear 13 drives the fine adjustment shaft barrel 23 on it to adjust the angle of stability, thereby adjusting the angle of the flange. In summary, the process involves firstly, using a roller conveyor to stably transport the flange to the processing area; then, the robotic arm on the processing support 3 operates, driving the hydraulic chuck to grab the flange and move it onto the horizontal adjustment disc 2 on the processing table 1. Subsequently, the adjusting seal is activated to fix and adjust the angle of the flange: horizontal clamping is achieved by the operation of the angle drive 17, which drives the bevel drive gear 18 to rotate, thereby driving the bevel ring rack 16 meshing with it, causing the convex ring slider 15 to rotate horizontally along the concave ring slide 14. This, in turn, drives the drive transmission shaft 5 through the bevel gear 13, and then drives a pair of horizontal adjusting threaded rods 9 to rotate through the horizontal gear set 12, causing the horizontal adjusting threaded tube to move and adjust the position of the three pairs of horizontal L-shaped adjusting blocks 10, thus adapting to flanges of different sizes and performing horizontal clamping; vertical clamping is achieved by energizing the lifting and lowering electromagnets in a pair of lifting and lowering magnetic adjusting blocks on the lifting and lowering limit block 11, generating variable magnetic force by changing the magnitude and direction of the current, driving the L-shaped magnets on the lifting and lowering extrusion block, causing the L-shaped lifting and lowering extrusion block to rise and fall within the lifting and lowering limit block 11, thereby achieving vertical clamping of the flange. Simultaneously, the negative pressure adsorption mechanism extends and retracts the negative pressure electric push rod 25 within the fine-tuning shaft barrel 23, pushing the negative pressure disc 26 and the negative pressure ring rubber ring 27 to generate negative pressure and adsorb and fix the flange. Furthermore, the angle and horizontal fine-tuning drive 19 operates, driving the fine-tuning bevel gear 20 to mesh with the fine-tuning bevel ring rack 21, causing the horizontal adjustment disc 2 to perform horizontal angle fine-tuning. Meanwhile, the negative pressure adjustment drive, through the negative pressure bevel gear set 13, drives the fine-tuning shaft barrel 23 to rotate, achieving local angle adjustment of the flange and ensuring drilling accuracy. The entire process encompasses transportation, handling, multi-directional clamping, negative pressure fixing, and angle adjustment, supplementing the angle fine-tuning mechanism of the horizontal adjustment disc 2 and improving the automation and adaptability of the equipment.
