Universal out-of-groove electroplating system for cylinder body

Abstract

The invention discloses a universal out-of-groove electroplating system for a cylinder body. The universal out-of-groove electroplating system for the cylinder body comprises an electroplating pretreatment device, an electroplating device and a universal fixture, wherein the universal fixture comprises an installation frame assembly and an auxiliary installation assembly, and the installation frame assembly comprises a fixed frame and a compression assembly; the fixed frame comprises a bottom plate and a frame fixed to the bottom plate; and the auxiliary installation assembly is used for installing a workpiece, installing the workpiece on the bottom plate after compensation in height and diameter, and compressing the workpiece through the compression assembly, and further used for guidinga pretreatment liquid into the cylinder body to form a pretreatment environment in an electroplating pretreatment procedure, guiding an electroplating liquid into the cylinder body in an electroplating procedure, and forming an electroplating environment between an anode and the workpiece through the anode. The universal out-of-groove electroplating system for the cylinder body is suitable for workpieces with various dimensions in the electroplating pretreatment procedure and the electroplating procedure, realizes seamless switchover for products, avoids the capacity loss of line stop, rapidlymeets a delivery need, reduces a switchover time for matured products to the minimum, and reduces the capacity to the lowest value.

Description

technical field [0001] The invention relates to a part of a cylinder electroplating device, in particular to a general-purpose out-of-slot electroplating system for cylinders. Background technique [0002] As the main component 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 trajectory for the piston assembly, thus forming a Power conversion environment. In the process of guiding the piston to reciprocate continuously, the inner wall of the cylinder and the piston rub against each other for a long time and at a high frequency, which reduces the useful power of the cylinder and consumes a part of the energy. In order to solve the above problems, the inner wall is electroplated, and the electroplating layer is used instead of the cylinder liner to solve the abo...

AI Technical Summary

Problems solved by technology

[0003] However, in the existing electroplating structure outside the tank, due to the different dimensions of the cylinder body (workpiece), the dummy anode needs to be replaced in the pre-plating treatment process, and the anode (especially the height) needs to be replaced in the electroplating process before it can be used for electroplating work. Normal operation requires the entire production line to be shut down, increasing loss and increasing production costs; and the fixtures are also different, with complex structures, and the replacement process needs to be done manually, reducing work efficiency
