CN-224198628-U - Be applied to pay-off tool of miniature nut production

Abstract

The utility model particularly relates to a be applied to pay-off tool of miniature nut production belongs to nut pay-off technical field, charging tray one side of disc vibrating screen is equipped with first material loading guide rail, and the one end of first material loading groove is equipped with blind selection coil in the built-in disc vibrating screen charging tray, the linear rail of linear vibrating screen is equipped with the second material loading guide rail that flushes relatively with first material loading guide rail. This design is based on disc vibrating screen's circular screen vibration material loading, with the mode of blind selection material loading with micro nut, vibration material loading is in the blind selection coil, at this moment, when the big radial of micro nut, then by the spacing support of blind selection coil and last vibration material loading, and when the little radial of micro nut, blind selection coil can't be spacing to it, fall back to in the disc vibrating screen, then carry at the vibration of first material loading guide rail, and the vibration of the last second material loading guide rail of linear vibrating screen is carried down, unload the feeding in the blanking frock with micro nut, its pay-off is more accurate, the continuous stability of pay-off is better again.

Description

Be applied to pay-off tool of miniature nut production Technical Field The utility model belongs to the technical field of nut pay-off, concretely relates to be applied to pay-off tool of miniature nut production. Background The miniature nut has wide application in various fields, mainly including mechanical manufacture, automobile manufacture, building engineering, ship manufacture, daily life and the like, for example, in the mechanical manufacture, the miniature nut is mainly used for connecting and fastening various machine parts to ensure the normal operation of mechanical equipment, and for example, in the automobile manufacture, the miniature nut is widely applied to the connection of wheels and axles to ensure the stability and safety of the wheels. Along with the wide application demands of miniature nuts, in the production application process, miniature nuts are continuously fed in batches by adopting a mechanical feeding mode, as shown in a feeding jig (publication No. CN 220431399U) for miniature nuts, which is disclosed by Chinese patent network, in the use process of the device, the nuts are poured into a nut bin, the nuts flow into a nut front and back screening mechanism along a buffering bin, at the moment, air blowing ports on two sides of the nut front and back screening mechanism begin to blow according to set frequency, in the air blowing process, the nuts with accurate front and back positions are conveyed into a buffering bin, the nuts with inaccurate front and back positions cannot pass through, the nuts with the front side flow into the buffering bin, then an air pipe of the buffering bin begins to blow to divide the nuts into four tracks to be conveyed to a discharging tail end, and an air blowing device at a discharging tail port begins to blow, so that the nuts are conveyed into an ultrasonic welding jig.
