AI Technical Summary

Technical Problem

It is difficult to realize the automatic assembly of folded articulated pairs, especially in the blind assembly structure of non-permeable holes in non-permeable holes, which have a small assembly space and limited field of view. It is difficult to achieve the high coaxiality and extremely small assembly clearance requirements of the pin shaft holes.

Method used

A device and method for hinging the pin shaft in the non-permeable hole of the folding articulated couple is adopted, including a work table, a mechanical grasping mechanism, a pin shaft transport mechanism, a pre-positioning mechanism, a final positioning mechanism and a moving platform. The final positioning mechanism is carried out in accordance with the ‘self-position reference principle’, and the secondary clamping is achieved using a pneumatic clamping mechanism to ensure the coaxiality and docking accuracy of the pin shaft hole.

Benefits of technology

It realizes efficient and precise assembly of folded articulated pairs, overcomes the problems of small assembly space and limited field of view, ensures high coaxiality and extremely small assembly clearance of the pin hole, and supports automated assembly.

Abstract

The invention discloses a hinge assembly device and method for a hinge pin in a non-through hole of a folding hinge matching part, and relates to the technical field of folding hinge matching part assembly.The hinge assembly device comprises a workbench and a mechanical grabbing mechanism, the mechanical grabbing mechanism is arranged at the left end of the workbench, and the workbench is provided with a hinge pin conveying mechanism, a pre-positioning mechanism, a final positioning mechanism and a motion platform; the motion platform is connected with the pre-positioning mechanism, and the final positioning mechanism is arranged at the right end of the motion platform. According to the hinge assembly device and method for the hinge pin in the non-through hole of the folding hinge coupling part, the problems that the outer surfaces of a basic part and a folding part are not accurately connected with the assembled surface, the assembly space is narrow and the like are solved, the influence of inaccurate positioning caused by machining errors of a part clamping surface and a positioning surface is eliminated, and the assembly efficiency is improved. The high-coaxiality automatic alignment of the axis of the pin shaft hole is realized, and the axial displacement of the pin shaft to a preset position is ensured.
