Integrated screening device of bolts

Abstract

The invention discloses an integrated screening device of bolts. The integrated screening device comprises a screw head screening unit and a screw rod screening unit. The screw head screening unit comprises a sorting box and a spiral feeder. Two first conveying belts are arranged in an outer shell of the sorting box, and a bolt conveying sorting channel with the gradually increased distance is formed between belt bodies located at the upper portions of the first conveying belts. The screw rod screening unit comprises a feeding box and a sorting belt. The feeding box comprises a supporting seat, an inclined box body fixed to the supporting seat and a second motor driving the box body to vibrate. Two sets of sorting mechanisms are fixed to the second conveying belt, and each sorting mechanism comprises an n-shaped frame, a detector and a material picking device from the position close to the feeding box to the position away from the feeding box in sequence, wherein the n-shaped frame limiting passing of the bolts with certain heights, the detector is used for detecting whether the bolts are inclined or not, and the material picking device is used for pushing the bolts away from the second conveying belt. A feeding rail is arranged between the box body and a material storage box body containing screw heads with qualified sizes, and the screening efficiency is high.

Description

【Technical Field】 [0001] The invention relates to the technical field of bolts, in particular to the technical field of a bolt integrated screening device. 【Background technique】 [0002] Bolt refers to a type of fastener consisting of two parts, a head and a screw, which need to be matched with a nut to fasten and connect two parts with through holes. At present, most of the detection devices for bolts are aimed at the thread and hardness indicators of the bolts, such as patent 201210101110.8 and patent 201310425246.9. However, if the width of the screw head of the bolt or the length of the screw is unqualified, it will not only affect the assembly accuracy of the entire equipment, but even cause potential safety hazards during the use of the equipment. The traditional method of detecting the width of the screw head or the length of the screw is a manual measurement method, and there is a problem that the screening efficiency cannot meet the mass production. Therefore, there i...
