The top of the base 2 is rotatably connected to a rotating shaft 6, and a turntable 7 is fixedly connected to the top of the rotating shaft 6. The top of the turntable 7 has four arc-shaped sliding grooves, and a sliding rod 8 is slidably arranged inside each arc-shaped sliding groove. The bottom of each sliding rod 8 passes through the sliding groove and is fixedly connected to a limit block. A gear 9 is fixedly connected to the surface of the rotating shaft 6. A limit frame 10 is fixedly connected to the top of the base 2. A rack 11 is slidably arranged inside the limit frame 10. A push plate is fixedly connected to the left side of the rack 11. A first cylinder 12 is fixedly connected to the top of the base 2, and the output arm of the first cylinder 12 is fixedly connected to the push plate.

[0025] The rack 11 meshes with the gear 9, and the top of the slide bar 8 is fixedly connected to the positioning block 5.

[0027] Four arc-shaped slides are arranged in a circular array, and a control panel 13 is fixedly connected to the top of the base 2.

[0028] Through the above technical solution, the base 2 serves as the base of the positioning mechanism, fixed on the machine base 1, providing stable support for the entire positioning mechanism. Four pillars 3 are vertically fixed on the base 2, their tops collectively supporting the positioning plate 4, ensuring the stability of the positioning plate 4. The positioning plate 4 is horizontally fixed to the top of the pillars 3, and its top has four positioning grooves arranged in a cross shape, providing a sliding track for the L-shaped positioning block 5. The L-shaped positioning block 5 slides within the positioning grooves, and by adjusting its position, it can adapt to the positioning requirements of flanges of different sizes. The rotating shaft 6 is vertically rotatably connected to the base 2, and its top is fixedly connected to the turntable 7. The turntable 7 is coaxially arranged with the positioning plate 4, ensuring smooth rotation. The top of the turntable 7 has four arc-shaped sliding grooves arranged in a circular array, corresponding to the positions of the positioning grooves. The sliding rod 8 slides within the arc-shaped sliding grooves, its bottom passing through the grooves and fixedly connected to... A limiting block prevents the slide rod 8 from dislodging from the slide groove. The top of the slide rod 8 is fixedly connected to the L-shaped positioning block 5. Therefore, the rotation of the turntable 7 will cause the slide rod 8 and the L-shaped positioning block 5 to slide in the positioning groove.

Two second cylinders are vertically mounted on the bracket 14, and a mounting plate is fixedly connected to their bottoms. The operation of the second cylinder 15 can drive the mounting plate to move up and down. The X-axis electric slide rail 16 is horizontally fixed on the mounting plate, enabling precise movement of the punching assembly in the X-axis direction. The Z-axis electric slide rail 17 is vertically mounted on the X-axis electric slide rail 16, enabling precise movement of the punching assembly in the Z-axis direction. By combining the X-axis and Z-axis electric slide rails, precise adjustment of the punching assembly's position can be achieved. The punching assembly includes a punching frame 18, a third cylinder 19, a mounting frame, a punching motor 20, and a drill bit 21. The punching frame 18 is fixed on the Z-axis electric slide rail 17. As the Z-axis electric slide rail 17 moves...
