[0040] At one end of the transverse sliding clamping rod 73 far away from the mounting clamping seat 74, a limiting protrusion 731 is integrally formed. By arranging the limiting protrusion 731 at one end of the transverse sliding clamping rod 73 far away from the mounting clamping seat 74, the translational sliding of the transverse sliding clamping rod 73 is limited to prevent the transverse sliding clamping rod 73 from sliding out of the card sliding sleeve frame 72 during translational sliding.

[0041] Working principle: When in use, by sliding open the frame door 21, the workpiece 5 is positioned on the clamping device 4 for clamping and positioning, and the clamping device 4 can be controlled to drive the workpiece 5 to rotate at a high speed;

[0042] And according to the distance length between the turning tool bit 64 and the workpiece 5, a turning tool bar 62 with a suitable length is selected for installation and fixation. The turning tool bar 62 is movably installed in the middle of the mounting seat 61. At this time, the limiting ring 621 contacts the outer side of the mounting seat 61, and the first bolt 622 movably penetrates through the end of the turning tool bar 62 and is threadedly installed on the mounting seat 61 to install and fix the turning tool bar 62;

[0043] Subsequently, according to the turning processing requirements, a suitable turning tool bit 64 is selected. The turning tool bit 64 is movably clamped at one end of the fixed rod seat 63 far away from the turning tool bar 62, and a third bolt 641 is threadedly installed on one side of the fixed rod seat 63 far away from the turning tool bar 62, so that the third bolt 641 movably penetrates through the turning tool bit 64 to fix the turning tool bit 64;

[0044] In the initial state, the fixed rod base 63 and the turning tool bar 62 are coaxially corresponding. When turning a workpiece 5 that needs internal turning processing, by activating the first linear electric rail 31 to drive the turning mechanism 6 to perform translational sliding in the X-axis direction, the fixed rod base 63, the turning tool tip 64, and the clamping sleeve frame 72 are moved through the slot with limited dimensions and placed inside the workpiece 5.

[0045] Subsequently, directly activate the second motor 763 to drive the drive screw 762 to rotate in the turning tool bar 62, thereby driving the drive clamping seat 76 to perform translational sliding in the clamping chute 761, driving the first rack 751 to perform translational sliding towards the side of the turning tool tip 64, thereby driving the first gear 75 to rotate through the first rack 751, and then controlling the middle drive shaft 71 to rotate, thereby controlling the clamping sleeve frame 72 to rotate around the rotation longitudinal axis 721 in the rotation receiving groove 601, and then controlling the fixed rod base 63 and the turning tool tip 64 to automatically rotate around the rotation longitudinal axis 721 inside the workpiece 5, so that the fixed rod base 63 and the turning tool bar 62 are in a vertical state.

[0046] Subsequently, activate the first motor 79 to drive the worm 781 to rotate, thereby driving the worm wheel 78 to rotate, and then controlling the drive longitudinal axis 771 to rotate between the two auxiliary seats 77, driving the two second gears 772 to rotate synchronously, thereby controlling the second rack 773 to perform translational sliding, and then driving the transverse sliding clamping rod 73 to perform translational sliding in the corresponding clamping sleeve frame 72, thereby driving the mounting clamping seat 74 to perform translational sliding, and then controlling the turning tool tip 64 to perform automatic translational sliding in the Y-axis direction, thereby realizing the automatic translational sliding of the turning tool tip 64 in the Y-axis direction inside the workpiece 5, automatically adjusting the Y-axis position of the turning tool tip 64 inside the workpiece 5, and making the end of the turning tool tip 64 contact the inner wall of the workpiece 5.

[0047] By controlling the clamping device 4 to drive the workpiece 5 to rotate at high speed, use the turning tool tip 64 to turn the inner wall of the workpiece 5. At the same time, by activating the first linear electric rail 31 to drive the turning mechanism 6 to perform translational sliding in the X-axis direction, drive the turning tool tip 64 to perform translational sliding in the X-axis direction inside the workpiece 5, and by activating the second linear electric rail 33 to drive the turning mechanism 6 to perform translational sliding in the Z-axis direction, drive the turning tool tip 64 to perform translational sliding in the X-axis direction inside the workpiece 5, thereby adjusting the position of the turning tool tip 64 inside the workpiece 5, facilitating the use of the turning mechanism 6 to directly perform turning processing inside the workpiece 5.

[0048] During this period, according to the processing requirements, the second motor 763 is turned on to drive the driving screw rod 762 to rotate reversely in the turning tool bar 62, thereby driving the driving clamping seat 76 to translate reversely in the clamping chute 761, driving the first rack 751 to translate and slide toward the side away from the turning tool bit 64, thereby driving the first gear 75 to rotate reversely through the first rack 751, and further controlling the middle drive shaft 71 to rotate reversely, thereby controlling the clamping and sliding sleeve frame 72 to rotate reversely with the rotation longitudinal axis 721 as the axis in the rotation and receiving groove 601, and further controlling the turning tool bit 64 to adjust the angle inside the workpiece 5, so that the turning tool bit 64 is more convenient for turning processing inside the workpiece 5;

[0049] After the turning processing inside the workpiece 5 is completed, first, control the clamping and sliding sleeve frame 72 to rotate reversely with the rotation longitudinal axis 721 as the axis in the rotation and receiving groove 601, so that the fixed rod seat 63 and the turning tool bit 64 automatically rotate reversely and reset inside the workpiece 5 with the rotation longitudinal axis 721 as the axis, so that the fixed rod seat 63 and the turning tool bar 62 are coaxially corresponding. Subsequently, drive the turning mechanism 6 to translate and slide reversely in the X-axis direction by turning on the first linear electric rail 31 again, so that the fixed rod seat 63, the turning tool bit 64 and the clamping and sliding sleeve frame 72 are moved out of the inside of the workpiece 5 through the slot with limited dimensions.
