Brush electroplating repair experiment platform for oil cylinder barrel

Abstract

The invention relates to a reproducing repair experiment platform and particularly relates to a brush electroplating repair experiment platform for an oil cylinder barrel. By adjusting four main parameters, which affect brush electroplating plating performances, such as brush electroplating voltage, relative movement speed of a workpiece and a plating pen, plating liquor flow rate, and relative pressure of the workpiece and the plating pen, optimal brush electroplating parameter value of the inner surface of the oil cylinder barrel can be obtained; the oil cylinder barrel is repaired through the obtained parameter value, so that dimension requirements and using performances can be satisfied well. According to the platform, a vertical structure is adopted, a plating brush adopts an inverter pulse power supply which is high in thickness measuring precision, and moreover, various parameters such as voltage are adjustable; the relative motion of the workpiece and the plating pen is decomposed into two major motions of linear feeding and rotation of the plating pen; each process step of the brush electroplating is automatically controlled by a PLC (Programmable Logic Controller); each of all different plating liquors has a respective specified plating liquor pump and a plating liquor box for realizing automatic applying and recycling. Besides, the brush electroplating repair experiment platform disclosed by the invention is simple and stable in structure, strong in practicability, high in automation degree, convenient to measure each parameter and capable of carrying out brush electroplating experiments, teaching and machining on the inner surface of a cylindrical workpiece.

Description

technical field [0001] The invention relates to a remanufacturing experimental platform, in particular to an experimental platform for electric brush plating repair of oil cylinder cylinders. Background technique [0002] The damage of the oil cylinder in the factory use accounts for a large part of the damage of the whole construction machinery parts. The manufacturing cost of the oil cylinder block accounts for about 35% to 55% of the entire oil cylinder assembly cost. If the cylinder block can be repaired, it can not only reduce the cost of remanufacturing the cylinder, but also achieve the reuse of steel and save steel resources. [0003] At present, the brush plating of hydraulic cylinders is mainly carried out manually. Since the brush plating is carried out manually, the brush plating is performed while measuring until the measurement results meet the size requirements. This not only increases the repair process but also increases the length of the measurement error. ...

AI Technical Summary

Problems solved by technology

At present, many brush plating technologies are used to repair small workpieces. Manual brush plating for single piece or small batch repairs requires a lot of manpower, material and financial resources, and the manual brush plating process is labor-intensive and efficient. Repaired surface quality is poor
