AI Technical Summary

Technical Problem

The existing spring assembly method is inefficient, depends on the operator's skill level, and is difficult to guarantee the coaxiality of the inner and outer springs and the consistency of the spring assembly quality, which affects the elastic performance and service life.

Method used

The system employs an inner spring positioning station, an outer spring positioning station, an installation mechanism, and a lifting mechanism to ensure that the inner and outer springs are coaxial and collinear. Precise assembly is achieved through the guidance of a guide rod and the fixing assembly of a pressing head. The cooperation between the guide rod and the pressing head ensures the coaxiality of the inner and outer springs.

Benefits of technology

This enables a highly efficient and precise spring assembly process, avoiding the problem of misalignment between the inner and outer springs after fitting, and improving assembly efficiency and product consistency.

Abstract

This utility model relates to the field of spring processing equipment technology, and in particular to a spring assembly fixture. It includes: an inner spring positioning station with an inner spring placement seat and a pressing head facing the inner spring placement seat; an outer spring positioning station spaced apart from the inner spring positioning station in the X direction, including an outer spring placement seat and a pressing head facing the outer spring placement seat, with the axes of the two springs vertically collinear when placed; an installation mechanism located on the side of the inner spring positioning station away from the outer spring positioning station, having an axially movable guide rod facing the spring axis and whose size is adapted to the inner diameter of the inner spring; and a lifting mechanism to ensure the two springs are coaxial and collinear. This fixture ensures the coaxiality of the two springs through the lifting mechanism, with the guide rod centrally guiding the fitting, and the pressing head cooperating with a limiting component to fix the position, achieving precise and efficient assembly, avoiding misalignment during fitting, and improving efficiency and product consistency.
