The outer end of the main shaft is provided with a clamping hole for installing an elastic chuck to clamp a cutter. The power of the tool turret of the machine tool is transmitted to the transmission shaft, and the transmission shaft drives the main shaft to rotate through two groups of bevel gears in the transmission structure for processing.
The second body is provided with two parallel baffles 1-4, and the rotating seat is rotatably positioned between the baffles.
The transmission structure comprises a first bevel gear 12-1, a second bevel gear 12-2, a gear shaft 11 with a third bevel gear 12-3 and a fourth bevel gear 12-4. The first bevel gear is coaxially connected with the transmission shaft, the second bevel gear is coaxially connected with the gear shaft and meshed with the first bevel gear, and the fourth bevel gear is coaxially connected with the main shaft and meshed with the third bevel gear.
The angle fine adjustment structure comprises a fine adjustment main shaft 5-1, a fine adjustment transmission shaft 5-2, a fine adjustment driving shaft 5-3, a first fine adjustment gear 7-1, a second fine adjustment gear 7-2, a third fine adjustment gear 7-3 and a fourth fine adjustment gear 7-4. The shaft hole 1-5 is arranged on one baffle plate of the second body, the inner wall of the shaft hole is provided with an inner convex ring 1-3, and as shown in fig. 7, the angle fine adjustment structure is arranged on the left side of the inner convex ring.
The fine tuning main shaft, the fine tuning transmission shaft and the fine tuning driving shaft are rotatably positioned in the second body of the tool apron body, the fine tuning main shaft is coaxially connected with the first fine tuning gear, the fine tuning transmission shaft is coaxially connected with the second fine tuning gear and the third fine tuning gear, the fine tuning driving shaft is coaxially connected with the fourth fine tuning gear, the first fine tuning gear is meshed with the second fine tuning gear, and the third fine tuning gear is meshed with the fourth fine tuning gear. The fine adjustment drive shaft is rotatably positioned in the shaft bore. Bearings are arranged at two ends of the fine tuning main shaft and the fine tuning transmission shaft.
The rotational axes of the fine tuning spindle, the fine tuning drive shaft, and the fine tuning drive shaft are parallel to each other (horizontal direction in fig. 7).
