Abstract

The invention provides a clamping-claw-type centering clamping device and belongs to the technical field of automobile parts. The clamping-claw-type centering clamping device comprises a driving disc, a cone and clamping claws; three spring supporting grooves are formed in the lower end of the cone and are distributed at equal intervals of 120 degrees; three inclined sliding grooves are formed in the cone and are distributed at equal intervals of 120 degrees; the spring supporting grooves and sliding grooves are mutually staggered by 60 degrees; a pushing rod is arranged on an upper support in a sliding up and down mode; a guide rod is arranged on the cone in a sliding up and down mode; a pushing plate is coaxially fixed to the lower end of the pushing rod; the pushing plate is connected with the upper end of a piston rod of a driving air cylinder; the upper ends of compression springs and the spring supporting grooves are attached; the lower ends of the compression springs and the upper end surface of the driving disc are attached; the clamping claws are slidably arranged on the sliding grooves of the cone; and clamping grooves at the lower ends of the clamping claws are clamped on the driving disc. Centering and clamping of a disc-shaped workpiece are achieved through the clamping claws, and the clamping claws are distributed at equal intervals of 120 degrees, so that the centering effect on the disc-shaped workpiece is good.

Description
