Automatic production line and production process for lock spring nuts

The invention belongs to the field of nut machining, and particularly relates to an automatic production line and a production process for an anti-loosening spring nut, and the automatic installation of the anti-loosening spring nut is realized by arranging a nut fixing assembly, a spring installation assembly and a driving assembly; by arranging a first pushing air cylinder, a pushing plate, a rotating motor and a clamping jaw, the spring washer is pushed to an expansion piece of a nut, the expansion piece is contracted through a claw of the clamping jaw, and therefore the spring washer can be arranged on the expansion piece of the nut in a sleeving mode conveniently; the visual sensor and the control module are arranged to detect the mounting state of the nut and the spring washer, so that qualification detection is performed on the matching state of the nut and the spring washer, and the percent of pass of the anti-loosening spring nut is improved; by arranging the polishing pieces on the outer side walls
