Helicla flute, on the one hand, make the movement of claw more link up steadily, on the other hand ensure therewith to match when parcel rotates to an angle
The multiple claws closed are always ensured that Concentric rotation, and the displacement on disk body I-shaped groove is equal.
Compared with prior art, the utility model has following beneficial technique effect：
Electronic self-centering chuck of the present utility model directly uses motor driven gear, and gear engagement drives external toothing and disk
Silk rotation, so as to drive claw to be operated, replaces existing camshaft bearing apparatus using self-centering, makes the making work of chuck
Skill more simplifies, and clamping range is bigger, and cost is lower, and reduces the mechanical connection between part, can use claw
During to the quick positioning of workpiece and clamping, improve the overall fit precision of chuck and operating efficiency, alleviate staff
Labor intensity.The design of archimedean spiral groove, makes the movement of claw more link up steadily, whole chuck design is ingenious, work
Skill is simple, installs and changes convenient, economical and practical, with the good market competitiveness.
