Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Embodiment: as Fig. 1, this numerical control tapping machine, comprise main spindle box 1, this main spindle box 1 is provided with servomotor 13, supporting component, Z axis feed arrangement, main shaft rotary actuator, rotary encoder 7, PLC control system 17, mair motor 2, adjustment block 20, tension block 22, motor cabinet 19, the encoder output shaft 8 of described main shaft rotary actuator is connected with the mover of rotary encoder 7, described rotary encoder 7 is connected with PLC control system 17, described PLC control system 17 is connected with servomotor 13, described supporting component is connected with the stator of rotary encoder 7.
Tapping stage mair motor 2 drives main shaft rotary actuator to rotate, the tapping tach signal recorded from main shaft rotary actuator is sent to PLC control system 17 by rotary encoder 7, PLC control system 17 is by calculating the relation of rotating speed and pitch, by signal to servomotor 13, Z axis feed arrangement is driven to realize main shaft 14 tapping.
After tapping completes, position signalling is fed back to PLC control system 17 by servomotor 13, processes through PLC control system 17, again signal is issued servomotor 13 and realizes Z axis location.
For the synchronism that raising main shaft 14 feeding and servomotor 13 rotate, the Timing Belt 11 in described Z axis feed arrangement need carry out pretension by the screw rotated between adjustment block, tension block.
Described main shaft rotary actuator is directly connected with rotary encoder 7, and counting is more accurate like this, and lower, the required part of cost is less.
Described Z axis feed arrangement uses driven by servomotor to make location more accurate.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
