Description

technical field [0001] The invention relates to an electric brush plating technology, in particular to a machine tool for electric brush plating of inner hole parts, especially connecting rods. The machine tool is aimed at parts with inner holes, and it is not only suitable for strengthening new parts, but also for repairing and remanufacturing of worn parts. Background technique [0002] Brush plating is a surface processing technology that uses electrochemical methods to reduce metal ions to metal and deposit them on the surface of metal or non-metal products to form a smooth and dense metal coating that meets the requirements. With the development of science and technology and production, brush plating technology involves more and more fields, and people's requirements for coating are getting higher and higher. At present, the application of metal coating has spread all over the various production and research departments of economic activities, and has great significanc...

AI Technical Summary

Problems solved by technology

[0006] One is the low efficiency of brush plating

Manual brush plating can only brush one plating pen at a time, and it cannot be brushed and plated in batches, which cannot meet the requirements of the workpiece repair industry

[0007] Second, brush plating standards are not uniform

Since brush plating is a manual operation with strong randomness and high technical requirements for workers, the qualification rate of brush plating workpieces will also be affected

[0008] Third, the waste of plating solution is serious

With the prolongation of the brush plating time, the concentration of metal ions in the plating solution decreases, but when the concentration of metal ions drops to about 40% of the original concentration, it is impossible to continue to obtain a qualified coating. In this case, the plating solution has to be scrapped. And at this moment, also have about 40% metal (generally nickel) in the plating bath to be unused, cause very big waste

[0009] Fourth, the plating pen needs to be replaced many times

The brush plating process includes multi-step processes such as electric cleaning, strong activation, weak activation, bottom layer and plating working layer. Since the plating solutions cannot be confused with each other, and the residual liquid in the coating material of the plating pen is difficult to clean, so In the brush plating process, the plating pen needs to be replaced in each step, which is extremely inconvenient to realize automatic brush plating

[0010] Fifth, the precision of parts clamping is high

[0011] Sixth, brush plating temperature is too high

At the same time, due to the small amount of plating solution contained in the parts during brush plating, the circulation of the plating solution is not smooth, so the heat generated by brush plating cannot be released and cooled in time, causing the temperature to rise rapidly and burn the coating

[0012] Seven is the higher cost

[0014] However, after long-term research, the inventor found that there are still many problems in the above-mentioned device, such as the combination of the rotation of the plating pen and the reciprocating motion of the base is not good, which makes the effect of brush plating not good.

In addition, the brush plating process requires multiple liquid changes and rinses. Due to the movement of the base, these procedures must be implemented in a static environment, and the efficiency is further limited.

The movement of the base is also likely to cause splashing of the plating solution, and problems such as poor sealing and loosening of the connecting rod connection

[0015] To sum up, the traditional method can no longer meet the requirements of automatic brush plating of inner holes, and even cannot guarantee qualified products, so it needs to be improved and enhanced.
