Pre-gluing machine of bolt

Abstract

The invention discloses a pre-gluing machine of a bolt. The machine is characterized in comprising a gluing head, a gluing opening turning on-off mechanism, a pushing mechanism, an electric control device system, a glue storing cylinder and an adjusting component, wherein the glue storing cylinder is connected with a glue inlet of the gluing head; the gluing head comprises a baffle ring of an opening of a gluing cavity, a gluing cavity sleeve, a gluing cavity sleeve seat, a pushing rod, a gluing cavity, a gluing opening and a glue storing cavity; an annular gluing opening is formed between the baffle ring of the gluing cavity and the gluing cavity sleeve; the pushing mechanism and the gluing opening turning on-off mechanism respectively comprises a gas cylinder; the gluing opening turning on-off mechanism and the pushing mechanism are driven by the gas cylinders to realize the sequential linkage; the pushing rod gradually and axially pushes a bolt of a work piece; glue liquid is peripherally, axially and continuously injected among screw thread teeth of the bolt of the work piece from the gluing opening along the bolt of the work piece; and the adjusting component can adjust the action position of the pushing rod, the turning on-off position of the gluing opening, the opening width of the gluing opening, and the opening pressure of the gluing opening. The pre-gluing machine can peripherally, axially and fast inject the glue into an elastic die cavity, can evenly and exactly glue, guarantees the gluing length and position, and guarantees the quality.

Description

technical field The invention belongs to the technical field of mechanical engineering, and relates to a bolt pre-applying machine, which is particularly suitable for pre-applying thread-locking glue on various bolts. Background technique As we all know, the commonly used method of pre-applying thread-locking glue on the bolts by hand is of poor quality and cannot guarantee the expected locking performance, and the production efficiency is low, and the production cycle can generally only reach 4 seconds per piece. The traditional bolt pre-gluing machine adopts the circumferential gluing method, which mainly includes the following three types: the first is that the workpiece bolts are rolled and coated on the gluing plate with a certain width; the second is that the workpiece bolts are clamped on the Rotate on the rotating shaft, use a certain width glue brush or sheet to brush glue in the circumferential direction; the third is to roll the workpiece bolts and a certain thic...
