The invention relates to an automatic lock piece press-fitting detection and correction device and method. The automatic lock piece press-fitting detection and correction device comprises a detection and correction rod (3) and an installation seat (1), wherein the upper portion of the detection and correction rod (3) is installed on the installation seat (1), the detection and correction rod (3) is hollow, a hollow inflation rod (5) is arranged in the detection and correction rod (3), an inflation port (6) is formed in a seat body of the installation seat and is communicated with the inflation rod (5), and a sealing ring (4) is arranged at the bottom of the detection and correction rod (3) and located on the outer side of the bottom of the inflation rod (5). The detection and correction rod descends and makes contact with an upper seat of an engine cylinder head, and the sealing ring (4) makes contact with the upper seat to play a role in sealing. The detection and correction rod continues to descend and compresses a spring of the upper seat, and at the time, if a locking piece is not pressed in place, the locking piece falls into the upper seat under the action of gravity. The detection and correction rod is inflated through the inflation port in the seat body of the installation seat, and whether the locking piece is pressed in place is further detected.
Description
technical field [0001] The invention relates to an automatic press-fit detection and correction method for a lock block. Background technique [0002] In the existing technology, on the automobile engine assembly line, the pass rate of the automatic press-fitting equipment for the cylinder head lock block is generally 90-95%. The problem to be solved urgently is that unqualified assembly needs to be reworked (manual assembly), which affects the efficiency The second is that there is a quality risk that the unqualified lock block for automatic pressing will fall into the inner cavity of the cylinder head. Contents of the invention [0003] The object of the present invention is to provide an automatic press-fit detection and correction method for the lock block, which can effectively realize the automatic press-fit detection and correction of the lock block. [0004] The technical scheme that realizes the object of the present invention: [0005] A lock block automatic pr...
