[0057] The workpiece is clamped by a through-type electric chuck 3. The first motor 4, driven by the reducer 2, rotates the workpiece via the through-type electric chuck 3, fixing the turning tool via the tool holder 16. The second motor 8, driven by the dual-output reducer 7 and then by the first lead screw 9, causes the first slider 6 to slide laterally. The third motor 11, driven by the second lead screw 12, causes the second slider 10 to slide forward or backward, adjusting the position of the turning tool. The fourth motor 14, driven by the support table 15, rotates the tool holder 16, adjusting the angle of the turning tool. The part is machined by turning, or by extending the second hydraulic cylinder 27, multiple sets of support plates 31 are extended to the right side of the through-type electric chuck 3. Then, the hole of the part is fitted onto the multiple sets of support plates 31. Multiple sets of third hydraulic cylinders 30 are extended simultaneously, so that the multiple sets of support plates 31 support the part, aligning the hole of the part with the center of the through-type electric chuck 3. Then, the fourth motor 14 is turned on, driving the support table 15 to rotate 180°. The fifth motor 19 is turned on, and through the meshing transmission of two sets of gears 18, the positions of the two sets of first electric clamps 20 are adjusted. Then, through the two sets of first electric clamps... The first set of electric clamps 20 or a set of first electric clamps 20 clamps the part, and then extends through two sets of first hydraulic cylinders 23. At the same time, two sets of guide sleeves 22 guide and limit the two sets of first hydraulic cylinders 23 respectively, so that the two sets of brake pads 24 squeeze the two sets of brake discs 25 respectively. The friction between the brake pads 24 and the brake discs 25 brakes the part and prevents the two sets of gears 18 from rotating. Then, by activating the sixth motor 42, the fourth slider 41 slides laterally through the fourth lead screw 40. Then, the fourth hydraulic cylinder 43 extends, causing the second electric clamp 46 to move downward. Then, the sixth motor 42... In reverse operation, the fixed seat 32 is inserted into the middle of the through-type electric chuck 3, so that the through-type electric chuck 3 clamps and fixes the fixed seat 32. Then, the frame 33 is released by the second electric clamp 46 and retracted by the fourth hydraulic cylinder 43, moving upward. Then, the handle 36 is clamped by the second electric clamp 46, and the seventh motor 45 is turned to drive the second electric clamp 46 to rotate, adjusting the position of the boring tool 38. Then, the turning mechanism moves the part closer to the boring tool 38, and the inner wall of the hole in the part is bored by the boring tool 38, thereby improving the practicality of the equipment.

[0058] The main functions achieved by this invention are: improving efficiency, improving control convenience, and improving processing accuracy;

[0059] 1. Improve efficiency: By cooperating with the turning mechanism and the boring mechanism, the inner wall of the hole in the irregular part can be bored, which improves the convenience and efficiency of the machining process.

[0060] 2. Improved control convenience: The position of the boring tool can be adjusted by changing the mechanism, ensuring the accuracy of the adjustment and facilitating the programming control of the equipment, thus improving control convenience;

[0061] 3. Improve machining accuracy: By centering the hole in the part through the centering mechanism, the accuracy of the boring tool in machining the inner wall of the hole in the part is improved.

[0062] The machine tool boring mechanism of this invention uses common mechanical methods for installation, connection, or setting. Any method that achieves the desired beneficial effect can be implemented. A protective shell and protective door can be installed on the worktable 1 according to actual usage.
