The invention discloses an automatic bolt lubricating and smearing device which comprises a feeding device used for conveying bolts to a grabbing
station; the material conveying device comprises a bolt
moving frame and two opposite side plates, the top end of each side plate is provided with a plurality of bolt groove positions arranged in the front-back direction, the bolt groove positions in the two side plates correspond to each other in a pairwise mode, every two opposite bolt groove positions are used for jointly supporting bolts, and the head and the
tail of screw rods of the bolts stretch out of the bolt groove positions. The bolt
moving frame is arranged between the two side plates in a lifting and front-back moving mode. The feeding and picking device is used for grabbing the bolts on the grabbing
station to a pair of bolt slots at the foremost end; the head gluing device is used for smearing the head of the screw with lubricating
grease; the
tail gluing device is used for smearing the
tail of the screw with lubricating
grease; and the discharged material picking device is used for grabbing the pair of bolts on the rearmost end bolt groove positions into the material receiving device. According to the automatic bolt
lubrication smearing equipment, the labor intensity of workers is reduced, and the smearing efficiency is greatly improved.
