Description

Technical Field

[0001] The invention belongs to the technical field of electrochemical polishing fixtures, and in particular relates to a conductive fixture for electrochemical polishing with an additional electrode. Background Art

[0002] With the continuous advancement of science and technology, the functional requirements of products in the fields of aerospace, automobile manufacturing and biomedicine are constantly increasing, resulting in increasingly complex component structures and gradually increasing requirements for component performance. For example, parts in the aerospace field need to withstand high temperatures, high pressures and frequent load changes, metal parts in the automotive industry are required to have fatigue resistance, corrosion resistance and high strength properties, and parts in the biomedical field usually require high precision, high finish and good biocompatibility. Therefore, metal parts in these fields must meet extremely high performance requirements, not only with excellent mechanical properties, but also with low surface roughness and high surface finish to ensure the service life, reliability and safety of the parts.

[0003] However, these metal parts with complex structures are often obtained after previous processes such as machining, near-net-shape forming and additive manufacturing. During these processes, there will be scratches, burrs, impurities and roughness on the surface of the parts to varying degrees. These defects will not only affect the performance of the parts, but may also cause early failure of the parts. For example, burrs and roughness on the metal surface can become the source of fatigue cracks and increase the risk of damage to the parts. Surface impurities or uneven oxide layers may affect the corrosion resistance of the metal and reduce the service life of the parts in harsh environments. Therefore, how to effectively remove these surface defects and improve the surface quality of parts has become an important issue in improving product performance.

[0004] As an advanced surface treatment technology, electrochemical polishing has many advantages that traditional mechanical polishing methods cannot match. Through electrochemical reactions, electrochemical polishing can remove tiny burrs and impurities on the metal surface, significantly improve the surface finish, reduce roughness, and thus improve the mechanical properties and corrosion resistance of parts. Specifically, the working principle of electrochemical polishing is to place the part as an anode in an electrolyte and pass an electric current. Under the action of the electrolytic reaction, the tiny protrusions on the surface of the part will be dissolved and removed, achieving a smooth surface effect.

[0005] Although electrochemical polishing is an ideal post-processing method, in actual applications, due to the complex shapes of parts, traditional electrochemical polishing fixtures are either only suitable for fixing simple flat parts or only suitable for fixing cylindrical parts with center holes, and it is difficult to effectively clamp irregularly shaped parts. Especially for complex metal parts, existing fixtures fail to fully consider the rotation and lifting movements required by the parts during the polishing process. Due to the lack of proper motion control, the surface treatment of parts is often limited to the part surface corresponding to the fixed cathode angle, which not only affects the consistency of the polished surface, but also makes it difficult to ensure continuous and uniform contact between the fresh electrolyte and the part surface, resulting in unsatisfactory treatment of the contactable surface, and may even cause some parts of the part to fail to achieve effective polishing effects, and also increase production costs and time.

[0006] On the other hand, the anode of the electrochemical polishing device faces the following challenges when contacting parts: for polishing parts with complex structures, the parts need to be completely immersed in the electrolyte. Once the electrolyte contacts the metal in the conductive area of ​​the anode, the current will choose a circuit with smaller resistance and react with the conductive metal preferentially. This will not only corrode the metal in the conductive area of ​​the anode, but also cause the workpiece in contact with the conductive metal to be unable to undergo an effective electrolytic reaction, which will not only damage the polishing equipment but also cause the surface post-treatment to fail.

[0007] Based on the above considerations and related needs, a conductive fixture for electrochemical polishing with an additional electrode is invented. Summary of the invention
