Height limit detection mechanism for inner assembly of tapered roller bearing

The invention discloses a tapered roller bearing inner assembly height limit detection mechanism, and belongs to the technical field of bearing machining devices. A standard part is placed on the rear side of the detection station, a through groove is formed in a table top where the standard part is placed, a driving mechanism is arranged at the bottom of the working table top, the driving mechanism is composed of a moving air cylinder and a lifting air cylinder and connected with a poke rod, the poke rod penetrates through the through groove to be inserted into an inner ring of the standard part, and the standard part is driven to move through the poke rod. The control program is provided with a benchmarking program, after a certain number of standard parts are detected, the standard parts are pushed into the detection station for benchmarking and timely correction, the accuracy of the measurement result is guaranteed, the detection mechanism and the movable sliding plate are connected through a conical slee
