A hair removing assembly for soft shaft processing

By combining the rotation and revolution of the grinding wheel with the pretreatment of spiral airflow, the problem of low contact between the grinding wheel's motion trajectory and the flexible shaft surface in the existing technology is solved. This achieves efficient and uniform deburring and impurity removal of the inner and outer layers of the flexible shaft, improving processing quality and equipment adaptability.

AI Technical Summary

Technical Problem

Existing flexible shaft processing equipment suffers from uneven deburring due to low contact between the grinding wheel's movement trajectory and the flexible shaft surface. The inner and outer steel wire winding structure is difficult to clean thoroughly, airflow cleaning is ineffective, and residual impurities affect processing quality and equipment lifespan.

Method used

The grinding wheel uses a combination of rotation and revolution to move, and the movement trajectory of the grinding wheel matches the spiral trajectory of the outer steel wire of the flexible shaft. It also combines spiral airflow and permanent magnet adsorption shaft for pretreatment and cleaning to ensure uniform grinding and removal of impurities on the inner and outer steel wire surfaces.

Benefits of technology

It achieves efficient and uniform deburring of the inner and outer surfaces of the flexible shaft, improves processing accuracy and equipment adaptability, reduces wear and impurity residue, and enhances deburring efficiency and cleanliness.

Abstract

The application discloses a hair removing assembly for soft shaft processing and relates to the technical field of metal hair removing treatment. The hair removing assembly comprises a hair removing machine main body, a driving module is arranged in the hair removing machine main body, the driving module comprises a driving motor, the soft shaft main body is divided into an inner layer and an outer layer, the inner layer steel wire is spirally wound on the inner surface of a center column, the outer layer steel wire is spirally wound on the outer surface of the center column in the opposite direction of the inner layer steel wire, the movement track of the grinding brush wheel during revolution matches the spiral track of the outer layer steel wire of the soft shaft main body, and the adhesion of the hair removing mechanism to the surface of the soft shaft is enhanced. Since the outer layer steel wire is spirally wound, the friction position of the outer end of the bristles of the grinding brush wheel with the outer layer steel wire matches the spiral track, so that the grinding brush wheel always maintains the best contact state with the surface of the steel wire during revolution. Whether the outer layer steel wire is convex or concave, the grinding brush wheel can always adhere to the surface, the continuity and stability of the hair removing operation are ensured, and the collision and abrasion of the grinding brush wheel and the soft shaft main body are reduced.
