Abstract
The invention relates to a positioning and self-locking clamping device used on a rotary automatic detecting worktable of a tappet body component assembly production line. The device structurally comprises a fixed worktable, the rotary worktable, positioning fixture components, a clamping cylinder component and a loosening cylinder component. The clamping cylinder component utilizes two inclined plane sliding plates with self-locking angles, wherein a transverse sliding plate is pushed by a pneumatic device, so as to enable a longitudinal sliding plate to move and then clamp tappet body components; and when no clamping push force exists, the transverse sliding plate cannot be pushed to move evenly by opposite reacting forces of tappet bodies, thereby achieving a self-locking clamping effect. The positioning and self-locking clamping device adopting a self-locking clamping manner has a structure that pneumatic elements of the clamping fixture and the loosening fixture are both mounted on the fixed worktable and separated from the rotation of the rotary worktable, and is used for replacing a complex structure that the original clamping cylinder rotates along with the rotary worktable, so as to simplify the structure and reduce the cost. The positioning and self-locking clamping device is suitable for positioning and clamping automatic devices similar to the rotary worktable structure.
