AI Technical Summary

Technical Problem

Existing electric linear actuators with telescopic rods suffer from problems such as short stroke, reduced accuracy, complex structure, inconvenient installation, and poor load adaptability, making them particularly difficult to meet the requirements of automated equipment in scenarios requiring long strokes.

Method used

The adjustable tail-end mounting shaft of the tail-end mechanism, combined with the wing nut and screw drive structure of the stroke mechanism, realizes the functions of installation angle correction and long stroke, asymmetrical load drive. The wing-type screw directly pulls the heavy object, extends the movement stroke and allows different pulling forces at both ends.

Benefits of technology

It achieves the effects of long stroke, high precision, convenient installation, strong load adaptability, and compact and reliable structure of electric linear actuators, and solves the problems of motion accuracy attenuation and installation complexity of traditional electric linear actuators.
