[0039] In this embodiment, the precision design of the first transmission assembly ensures that the power is efficiently and stably transmitted from the floor-standing boring machine to the front end of the processing tooling. The transmission rod 5 is horizontally installed in the fixed housing 1, and the keyway at its end is precisely matched with the fixed key 8 protruding on the keyway fixing plate 7 of the floor-standing boring machine. It is locked to the end face of the transmission rod 5 with two screws to form a firm connection, ensuring direct power transmission, so that the boring machine can drive the transmission rod 5 to rotate synchronously when it rotates after connecting the keyway fixing plate 7.

The one-piece flange at one end of the connecting cylinder 14 is fixedly sleeved with a ring gear 37, which forms an effective linkage with the transmission gear 39 rotatably mounted on the central shaft 38 at one end of the mounting seat 13. The meshing of the transmission gear 39 and the ring gear 37 ensures the precise transmission of power and the fine adjustment of the angle. The second worm gear 40 fixedly sleeved at one end of the central shaft 38 can form a meshing with the worm 28. This design not only provides an additional transmission path, but also realizes fine adjustment of the angle adjustment through the deceleration and torque-increasing effect of the worm gear, thereby ensuring high-precision control of the tool processing angle. The addition of the angle adjustment assembly not only enhances the flexibility and adaptability of the tooling system, but also ensures high precision and stability during the processing, provides key technical support for the precision processing of complex components, and significantly improves the processing efficiency and quality.

[0054] In a further preferred embodiment of the present invention, an indicator block 41 is fixedly installed on one side of the mounting seat 13 , an arrow is provided on the indicator block 41 , an angle scale line 42 is provided on the outer wall of the connecting tube 14 , and the arrow on the indicator block 41 points to the angle scale line 42 .

[0055] In this embodiment, a clear arrow is provided on the indicator block 41 fixedly mounted on one side of the mounting seat 13, and the angle scale line 42 provided on the outer wall of the connecting tube 14 corresponds to the arrow. This design provides an intuitive angle reading method for the operator. When the angle of the connecting tube 14 changes, the arrow on the indicator block 41 will point to the corresponding position on the angle scale line 42, directly displaying the current angle of the connecting tube 14, so that the operator can accurately control the processing angle of the tool and ensure the processing accuracy. This innovation in details not only simplifies the confirmation steps after the angle adjustment and improves the adjustment efficiency, but also effectively avoids the processing deviation caused by the angle reading error, provides a reliable visual reference for the high-precision processing of complex components, and is an important aid to improve the processing quality and efficiency.

[0056] In another preferred embodiment of the present invention, two symmetrical L-shaped blocks 43 are installed on the mounting seat 13, and the flange of the connecting tube 14 is located between the two L-shaped blocks 43. A locking screw rod 44 is threadedly installed on the L-shaped block 43, and the locking screw rod 44 is pressed against the flange of the connecting tube 14 to fix the connecting tube 14 after the angle is adjusted.

[0057] In this embodiment, two L-shaped blocks 43 symmetrically mounted on the mounting seat 13 form a clamping structure, stably placing the flange of the connecting tube 14 between the two. The locking screw rod 44 threadedly mounted on the L-shaped block 43 can accurately press against the flange of the connecting tube 14. This design ensures that the connecting tube 14 can be firmly fixed after adjusting the angle, effectively preventing any angle deviation during the processing, and ensuring the processing accuracy and safety. The use of the locking screw rod 44 not only simplifies the fixing process and improves the operating efficiency, but also adapts to the precise control of the angle of the connecting tube 14 under different processing requirements through its adjustability, which is a key link in achieving high precision and high stability of the tooling system.
