AI Technical Summary

Technical Problem

Existing miniature columnar low-frequency vibrators have problems preventing resonance and heat accumulation in low-frequency vibration environments, especially under high load conditions, which can lead to decreased equipment performance or workpiece damage.

Method used

It adopts a suspension structure and coolant system, and uses the same polarity repulsion characteristics of magnets to replace traditional springs. Combined with multiple magnetic plates and spring structure, it reduces eddy current loss and enhances stability. The impact force is reduced by mounting bracket and telescopic rod.

Benefits of technology

It effectively isolates external vibration interference, reduces heat accumulation, improves equipment efficiency, enhances stability and vibration experience, prevents resonance, and extends equipment life.

Abstract

This utility model provides a miniature columnar low-frequency vibrator, relating to the field of vibrator technology. It includes a magnetic sleeve, inside which are an outer cover, a sealing mechanism, and a vibration mechanism, with the vibration mechanism located inside the sealing mechanism. A damping mechanism is located below the magnetic sleeve. A set of fixing rings is installed on both sides of the outer wall of the positioning shaft. A set of second springs is installed between the fixing rings and the magnet. A set of first springs and a telescopic rod are installed between the mounting brackets of the damping mechanism. The first springs dampen vibrations, and the telescopic rods reduce the force exerted by the low-frequency vibrator body on other devices during vibration. This effectively solves the problem that in low-frequency vibration environments, due to the high energy of low-frequency vibrations, the vibration isolation device needs to withstand a large impact force.
