AI Technical Summary

⚠Technical Problem

Existing electric cylinders suffer from reduced accuracy and lifespan after prolonged linear motion due to the lack of a stabilizing mechanism in the power lead screw or wear of the wear-resistant strips leading to eccentricity. Additionally, the one-piece connector design results in high replacement costs and limits applicable scenarios.

⚗Method used

The stabilizing mechanism includes a convex key, a rotating ring, and a stabilizing ring. Combined with the disassembly and assembly mechanism and sealing cover design, it avoids friction damage to the wear-resistant strip, supports the installation of multi-purpose connectors, and reduces replacement frequency and cost.

🎯Benefits of technology

It improves the service life of electric cylinders, enhances application precision, adapts to multiple application scenarios, and reduces maintenance costs and material waste.

Abstract

This utility model discloses a long-life, multi-purpose electric cylinder, relating to the field of electric cylinder technology. The utility model includes a housing, a threaded transmission assembly, a power screw, and a spindle. The threaded transmission assembly is disposed within the housing and includes a piston and a ball bearing. The ball bearing is threadedly connected to the power screw, and when the power screw rotates, it drives the ball bearing to move in the X-axis direction. A stabilizing mechanism includes a key, a rotating ring, and a stabilizing ring. The key is connected to the power screw, and the rotating ring rotates within the stabilizing ring in a direction perpendicular to the X-axis. This utility model eliminates the need for wear-resistant strips connected to the stabilizing ring to rub against the inner wall of the spindle, reducing the need for frequent replacement of wear-resistant strips and preventing frictional damage to the inner wall of the spindle. This increases the service life of the electric cylinder, is adaptable to various electric cylinder applications, reduces maintenance costs and waste, and makes it easier to observe the wear and replacement of the slide bars.
