A multi-station needle guide post assembly

Abstract

The utility model relates to metal processing technical field, concretely relates to a kind of multi-station roller needle guide pillar assembly, comprising: sleeve, the inner wall sliding connection of sleeve has roller needle bushing, the inner wall sliding connection of roller needle bushing has column, the outer wall of sleeve is equipped with support device. Through support device, by being equipped with thread hole and limiting bolt in the circumferential, length direction array distribution of sleeve and connecting bracket, the circumferential angle and axial position of support device can be adjusted, cooperate with the relative sliding design of inclination adjusting hole and locking bolt of variable position support, the supporting angle of different stations can be adjusted, through regular polygon roller needle bushing and column, avoid guiding deviation, roller needle bushing converts the sliding friction between column and sleeve into rolling friction, reduce movement resistance and component wear, both meet the requirement of axial positioning in stamping, assembly and other scenes, and it is favorable to reduce precision attenuation after long-term use.

Claims
