Automobile body electrophoresis exhaust tool

By designing an electrophoretic exhaust fixture for car bodies, and utilizing a combination of U-shaped exhaust pipes and threaded pipes, the problem of air residue caused by poor exhaust in traditional fixtures was solved. This enabled efficient exhaust of air from inside the car body and uniform filling of the electrophoretic liquid, thereby improving coating quality and sealing performance.

AI Technical Summary

Technical Problem

Traditional tooling suffers from poor exhaust, resulting in residual air inside the vehicle body. This prevents the electrophoretic coating from fully filling the complex structure, creating air stagnation areas. Consequently, the electrophoretic coating may not cover these areas, increasing the risk of corrosion and causing uneven coating thickness.

Method used

Design a vehicle body electrophoresis exhaust fixture, including a combination of a U-shaped exhaust pipe and a threaded pipe to expand the exhaust coverage area. With the help of double sealing rings for the intake pipe and exhaust hole, it ensures that the air inside the vehicle body is smoothly discharged. It can also be adapted to different vehicle models through support plates and slot structures to avoid interference.

Benefits of technology

It improves exhaust stability, reduces air residue and electrophoretic fluid filling blind spots, reduces pinhole and flow mark defects, extends seal life, and reduces maintenance costs.

Abstract

The utility model relates to the technical field of exhaust tools, and discloses a vehicle body electrophoresis exhaust tool which comprises an electrophoresis cell, an installation groove is formed in the outer wall of the electrophoresis cell, an observation window is fixedly installed in the installation groove, and a vehicle body is arranged in the electrophoresis cell. And the exhaust components are arranged inside and at the top of the electrophoresis cell. Through the arrangement of the U-shaped exhaust pipe and the threaded pipe, the exhaust coverage area is enlarged, the exhaust efficiency of air in an automobile body is improved, local bubble residues caused by unsmooth single-side exhaust are effectively avoided, an electrophoresis liquid filling blind area is effectively avoided, and the needle hole and flow mark defect rate is reduced; meanwhile, the exhaust cavity of the exhaust fixing bottom box serves as a buffer cavity, exhaust interruption caused by liquid level fluctuation of an electrophoresis cell or sudden change of exhaust pressure is avoided, and the effect of improving exhaust stability and product quality is achieved.
