A new type of electroplating hanger for the inner wall of the oil cylinder

Abstract

The invention discloses a novel electroplating hanger for the inner wall of an oil cylinder, which belongs to the technical field of electroplating. It includes a cathode hoisting assembly for clamping the upper end of the cylinder to be plated, and an anode positioning assembly for clamping the lower end of the cylinder to be plated, and an anode hoisting assembly is hung on the cathode hoisting assembly; the cathode hoisting assembly includes A pair of oppositely arranged vertical plates, the vertical plates are connected with cathode hooks, and V-shaped hooks are fixed on the outside of the vertical plates; the two vertical plates are fixedly connected by a pair of intermediate plates, and the two intermediate plates are provided with Opposite bayonets; the lower ends of the two vertical plates are fixedly connected with a cathode card circle for clamping the upper end of the cylinder to be plated. The anode hoisting assembly, anode positioning assembly, and cathode hoisting assembly of the present invention are combined with each other to simplify the parts, break the original complex structure, realize an integrated tooling, realize rapid installation and overall hoisting, improve the electroplating efficiency, and ensure the electroplating quality.

Description

technical field [0001] The invention relates to the technical field of electroplating, in particular to a novel electroplating hanger for the inner wall of an oil cylinder, which is suitable for the electroplating process for the inner wall of a hydraulic oil cylinder. Background technique [0002] Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. It is a process of using electrolysis to attach a layer of metal film to the surface of metal or other materials, so as to prevent metal Oxidation (such as rust), improve wear resistance, electrical conductivity, reflective properties, corrosion resistance (copper sulfate, etc.) and enhance the appearance. [0003] According to the shape of the parts, the technical requirements of the coating, the electroplating process and the size of the equipment, there are different types of hangers. For example, there is a difference between au...

AI Technical Summary

Problems solved by technology

[0005] 1. The existing anode positioning plate is installed separately. Place the anode positioning plate at both ends of the cylinder, and then use several thin iron rods slightly longer than the cylinder to pass through the anode positioning plate, and then fix it. Cylinders of different lengths need Tooling cannot be used universally for different irons;

[0006] 2. The one-by-one installation method is difficult to install. It is difficult to achieve precise installation due to the cooperation of the installers and the proficiency of the operation. It cannot guarantee a good anode positioning ability, and is easily affected by the size of the workpiece, and the conductivity is also poor.

It not only wastes resources but also increases the difficulty of operation, and the installation efficiency of tooling is low;

[0007] 3. When entering the plating tank, the cathode and anode are hoisted separately, and there is eccentricity between the anode and the cylinder, resulting in uneven thickness of the coating
