Afterwards, will not vary with each individual.
To achieve these goals, the utility model provides a kind of chuck automatic clamping device, including mandrel, the mandrel
Head be arranged with pivoted housing, the pivoted housing can be provided with claw, in the mandrel around central axis between the mandrel and pivoted housing
Groove is provided with pivoted housing socket place end face, three grooves are evenly distributed on the same circumference using its axis as the center of circle
On, spring one is provided with the groove, the spring one can make the pivoted housing after rotation automatically reset.
As preferable technical scheme, the mandrel is provided with twice chute, and the chute bottom land is circular arc, corresponding institute
To state and four circular holes are uniformly provided with the pivoted housing of chute, the circular hole penetrates the jacket wall of the pivoted housing, and ball is provided with the circular hole,
The part that the ball is higher by pivoted housing jacket wall is pressed into chute by spring two.
As preferable technical scheme, the groove is into arc-shaped, and central angle angle is corresponding to the groove length
30°~45°。
As preferable technical scheme, the spring one is extension spring, and described one end of spring one is fixed in mandrel, separately
One end is fixed on pivoted housing.
As preferable technical scheme, the outside of the pivoted housing is additionally provided with protective jacket, leads between the protective jacket and pivoted housing
Cross threaded connection, the rotation direction of the screw thread with make claw turned when loosening pivoted housing direction it is identical.
The utility model is applied to the little occasion of some clamping force demands, can be pressed from both sides automatically after clamping thing is put into
Tightly, improve clamping efficiency, and fast changeable spring selects different clamping forces, to meet different clamping force demands,
After clamping force setting, it will not vary with each individual.
