Positioning clamp with anti-clamping mechanism

Abstract

The invention discloses a positioning clamp with an anti-clamping mechanism, and relates to the technical field of storage battery production and processing. A telescopic cylinder drives a movable plate A to move to drive an L-shaped baffle to clamp a storage battery, and when the telescopic cylinder completely stretches out, the end of a movable column is inserted into an annular groove locking position; when the telescopic cylinder shrinks to a complete return position, the inclined plane B of the driving block A and the inclined plane A of the driving block B interact to push the movable column to slide out of the annular groove, and the spring A immediately drives the movable rod to move in the direction away from the storage battery to avoid jamming; before the telescopic cylinder is controlled to start to contract until complete contraction is completed, the movable rod keeps the telescopic cylinder at a position in a complete extension state, and the movable rod is utilized to prevent the storage battery from deviating and prevent the storage battery from moving along with the L-shaped baffle due to adhesion.
