Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment 1:
As shown in Figs. 1-5, a kind of simple dynamic poise device of CNC lathe, including spindle chuck 1, axis fixation hole 2, chuck jaw
3, fluting 31, fitting strip 32, workpiece elbow 4, bolt 5, mounting hole 51, clump weight 6, annulus 61, the first screw thread layer 62 and the
Two screw thread layers 63 are provided with axis fixation hole 2 on spindle chuck 1, and axis fixation hole 2 is located at the center of spindle chuck 1, and main shaft
The surface of chuck 1 is equipped with chuck jaw 3, and the quantity of chuck jaw 3 is three, and center of three chuck jaws 3 about spindle chuck 1
Angularly it is distributed, workpiece elbow 4 is located therein between two chuck jaws 3, clump weight 6 is provided on another chuck jaw 3, and
And bolt 5 is provided at the center of clump weight 6.
In the embodiment: the contact surface of chuck jaw 3 and workpiece elbow 4 is provided with fluting 31, and the avris of fluting 31 is distributed with
