Embodiment 1
[0021] Example 1: see attached Figure 1 to Figure 5 . It includes Dota ( Figure 5-1 ), the guide seat in the turret ( Figure 4-4 ) is indirectly fastened to the base ( Figure 5-4 ), a round hole ( Figure 4-3 ) so that the main shaft drive shaft ( Figure 4-2 ) is connected to the transmission, and the outer surface of the guide seat has a zigzag guide groove ( Figure 4-5 ), the distance between the upper and lower ends is symmetrical with the center of the circular hole on the normal plane. Slotted flat head shank seat ( figure 1 -8) The tail has a flat head in the shape of a line and is located in the in-line guide groove in the guide seat. The in-line flat-head tool shank seat is matched with the in-line guide groove on the guide seat and rotates along the guide seat. Wear-resistant sheet ( Figure 4 -6) It is built into the in-line guide groove of the guide seat and the wear-resistant sheet is located on the left side and the right side of the in-line guide ...
Embodiment 2
[0026] Embodiment 2: On the basis of embodiment 1, the rotation method of the special-purpose rotary turret of the turning and milling CNC center, when the turret rotates, it drives the in-line flat head shank seat ( figure 1 -8) With the guide seat in-line guide groove ( Figure 4-5 ) for a 360-degree cyclic rotation, after the turret rotates at a specific angle, the in-line flat head at the tail of the shank seat turns into the in-line groove of the spindle drive shaft ( Pic 4-1 ), the main shaft drive shaft ( Figure 4-2 ) to rotate to rotate the in-line flat head shank seat. At this time, a V-groove shank ( Picture 1-1 ) and the tool to process the part.
Embodiment 3
[0027] Embodiment 3: On the basis of Embodiment 1, a turret rotation structure, which includes a turret, the turret rotation adopts a three-plate clutch structure and is composed of an indexing toothed plate A ( Figure 5-3 ), indexing ring B ( Figure 5-2 ), the indexing ring C ( Figure 5-5 ) and friction discs ( Figure 5 -6) Composition, the indexing ring A is fastened on the turret ( Figure 5-1 ), the indexing ring C is fastened on the base ( Figure 5-4 ), the indexing chain B can perform piston movement, the teeth of the indexing chain A and the indexing chain C are aligned, and the indexing chain B performs the teeth of the indexing chain A and the indexing chain C. Bite lock, servo motor and worm ( Figure 5 -9) and drive the worm gear through the worm ( Figure 5 -7) Turn, the worm gear is installed on the cylindrical helical gear shaft ( Figure 5 -8), the outer circular helical teeth of the indexing tooth plate A mesh with the cylindrical helical gear shaft ...
