Plating pretreatment device for cylinder electroplating

Abstract

The invention discloses a pre-plating treatment device for cylinder electroplating. The device comprises a treatment unit, a liquid supply assembly and a liquid return assembly. The processing unit comprises a substrate provided with an upper plane for placing tooling, and the tooling is used for installing a workpiece; the substrate is located on the upper plane, and provided with a liquid inletand a liquid return port, and the inner cavity of the workpiece communicates with the liquid inlet and the liquid return port after the tooling is placed on the upper plane; the liquid return assemblycomprises a communicating pipe communicating with the liquid return port, and an outlet of the communicating pipe is higher than the height of the to-be-treated part of the workpiece. On the basis ofthe principle of a communicating device, pre-plating treatment liquid in the workpiece maintains a set height, the liquid inlet and a liquid outlet can be both set in size range to adapt to double cylinders, single cylinders and cylinders with different cylinder hole distances, so that the device has universality, different workpieces can be replaced and directly installed on the device without stopping the production line, the loss of production capacity due to line stopping is avoided, switching time of mature products is shortened to the greatest extent, and the loss of production capacityis minimized.

Description

technical field [0001] The invention relates to a cylinder electroplating device component, in particular to a pre-plating treatment device for cylinder electroplating. Background technique [0002] As the main part of the engine, plunger pump, reciprocating compressor and other equipment, the cylinder block is used to form the working space together with the piston and the cylinder head; taking the engine as an example, it forms the combustion chamber and provides the movement track for the piston assembly, thus forming power conversion environment. When the cylinder guides the piston to reciprocate continuously, the inner wall of the cylinder and the piston rub against each other for a long time and at high frequency, which reduces the useful power of the cylinder and consumes part of the energy. In order to solve the above problems, electroplating is adopted on the inner wall, and the electroplating coating is used to replace the cylinder liner to solve the above problem...

AI Technical Summary

Problems solved by technology

In the existing pre-plating process of dynamic electroplating, a dummy anode is generally installed on the station (imitating the electroplating process for pre-plating treatment) to realize the implementation of the pre-plating treatment process. However, different workpieces have different heights. The false anode needs to be replaced; for the double-cylinder cylinder, since the distance between the cylinder holes is not fixed, the set pre-plating treatment station of the false anode cannot be changed, and it is not compatible with single-cylinder / double-cylinder products, and needs to be shut down for adaptation processing, increasing loss, increasing production costs
