Nylon ring nesting device for nylon self-locking nut

Abstract

The invention discloses a nylon ring nesting device for a nylon self-locking nut. The nylon ring nesting device comprises a feeding mechanism, a detection mechanism and a loading and unloading mechanism; the feeding mechanism comprises a lifting unit and a downward pressing unit; the downward pressing unit comprises an L-shaped plate, two pressing plates, two air cylinders I and two air cylindersII; the center of a horizontal plate of the L-shaped plate is provided with a rectangular through slot, and the horizontal plate is located above a round turntable; each pressing plate comprises a semi-circular sleeve and an L-shaped side plate; horizontal parts and vertical parts of the L-shaped side plates are slidably connected with telescopic rods of the air cylinders I and the air cylinders II respectively; the air cylinders I and the air cylinders II are fixedly connected with an L-shaped rack; the detection mechanism comprises a metal sheet I and a metal sheet II; the metal sheet I is arranged on the surface of a wooden workbench and right below the L-shaped plate; the metal sheet II is arranged at the bottom surface of the semi-circular sleeve of one of the pressing plates; when there is a nylon ring, the nylon ring is insulated, and the two metal sheets are not conductive; and when there is no nylon ring, the two metal sheets are in contact with a nut body, and can be conductive.

Description

technical field [0001] The invention relates to the field of production and processing of nylon self-locking nuts, in particular to a nylon ring nesting device for nylon self-locking nuts. Background technique [0002] Nut is a common fastener, generally used in conjunction with bolts, many bolts and nuts are used in vibration situations, vibration will also cause the connection between bolts and nuts to loosen, resulting in potential safety hazards, so self-locking nuts are used Nylon self-locking nuts are a kind of self-locking nuts. Compared with ordinary nuts, nylon self-locking nuts add a layer of nylon ring. The nylon ring is ring-shaped. The inner diameter of the nylon ring is slightly larger than the threaded hole diameter of the nut. In such use, the external thread of the bolt and the nylon ring are extruded to deform the nylon ring. After installation, the nylon ring and the thread are completely squeezed into contact, and the extruded nylon ring produces a large ...

AI Technical Summary

Problems solved by technology

[0004] The disadvantages of the above-mentioned device are as follows: 1. The outer diameter of the nylon ring is highly compatible with the step hole, and the nylon ring itself is made of soft material, so the positioning requirement for the step of inserting the nylon ring into the step hole is high. The device, the blanking hole and the pressing device realize this step, and the positioning accuracy can be further improved; 2. The detection device detects that there is no nylon ring, and the whole device stops, and then the nylon ring is manually inserted, which reduces the efficiency. , also increases the workload of workers
