AI Technical Summary

Technical Problem

The dynamic coil guide structure of the traditional electric impact stage is prone to position deviation when it withstands the impact force on the side, resulting in faults such as jamming or guide deviation during operation.

Method used

An electric impact table dynamic coil structure including a dynamic coil frame, a dynamic coil winding and a guide structure is designed. The dynamic coil frame consists of a support part and a limiting part. The support part is composed of an arcuate external support plate and an internal support frame. The limit part limits and presses the dynamic coil winding axially through the limiting edge and screw structure; the guide structure adopts a detachable guide rod and connecting plate design.

Benefits of technology

Through the axial limiting and compression structure, the dynamic coil winding is ensured to be stable and unrotated during the impact process, which improves the impact indicators and guidance accuracy, extends the service life, and reduces the occurrence of faults.

Abstract

A moving coil structure of an electric impact table comprises a moving coil framework, a moving coil winding and a guide structure. The moving coil framework comprises a supporting part and limiting parts connected to the two axial ends of the supporting part, and the axial direction of the supporting part is the impact direction of the moving coil structure; the moving coil winding is wound on the supporting part and is axially limited by the two limiting parts; the guide structure is detachably connected to the moving coil framework and extends in the impact direction. The limiting parts are arranged at the two ends of the supporting part of the moving coil framework, so that the moving coil winding can be axially compressed, the moving coil winding can be compact, the axial position is fixed, radial rotation is avoided, and the moving coil winding is stable when being impacted back and forth along with the moving coil framework.
