Pre-plating dust removal device for cylinder body electroplating

Abstract

The invention discloses a pre-plating dust removal device for cylinder body electroplating. The pre-plating dust removal device comprises a dust removal tank and an ultrasonic generating assembly. Theultrasonic generating assembly comprises transduction heads and a driver, the transduction heads are located on the outer side of the lower portion of the dust removal tank obliquely, and the ultrasonic generating directions of the transduction heads are right opposite to the range where an inner hole of a workpiece is located when the workpiece is put in the dust removal tank. A chemical dust removal manner is avoided, and the requirements of environmental protection are met. Meanwhile, the structure that a transduction rod is put in the inner hole of the workpiece in the prior art is abandoned, the obliquely-arranged transduction heads are adopted, ultrasonic waves directly act on the inner hole of the workpiece (the dust removal tank is located on the upper portion), and the requirements of dust removal of pre-plating treatment of most current cylinder bodies can be met. The pre-plating dust removal device cooperates with a tool matched with the workpiece, a production line does not need to stop, different workpieces are replaced to be directly mounted on the device, thus, the device is suitable for existing workpieces with various sizes, seamless switching of products is achieved, capacity losses of line stop are avoided, the delivery requirements are rapidly met, the switching time of mature products is shortest, and the capacity losses are reduced to be minimal.

Description

technical field [0001] The invention relates to a cylinder body electroplating device component, in particular to a pre-plating ash removal device used for cylinder body 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 ...

AI Technical Summary

Problems solved by technology

The existing dynamic electroplating pre-plating deashing generally adopts ultrasonic ash removal, which can be applied to almost all ash-hanging materials encountered at present, and can achieve perfect ash removal effect under the premise of sufficient ultrasonic power , but the equipment capacity requirements are high. Even if the domestic ordinary ultrasonic vibration heads are fully arranged at the bottom and surrounding of the tank, it is difficult to achieve 100W / L power. If you want to meet the requirements, you must use ultrasonic transducer rods to directly connect the energy source It is possible to achieve this power requirement in the local space of the cylinder bore only if it is placed inside the cylinder bore; however, under the same power requirements, domestic ultrasonic transducers are often too thick in diameter to be placed in the cylinder bore, or even if they can be placed , and the gap is too small, it is easy to collide with the workpiece on the hanging basket

Imported ultrasonic transducers are expensive

The main thing is that since the energy emission of the ultrasonic source is also a sinusoidal waveform, it will form a strong and weak ash removal effect on the inner wall of the cylinder bore. In severe cases, "zebra patterns" will appear. Reversed, so the requirements for equipment manufacturing and control are high; and the structure of placing the transducer rod in the cylinder is less versatile, especially when switching between double cylinder products, due to different hole center distances, it must be accurate Adjust the position of the transducer

It must be adjusted once after switching, and non-professionals cannot operate it. If the position is adjusted incorrectly, the workpiece will be scratched, or a crash will occur, causing serious damage to the production line.
