Abstract

The invention relates to a micro-pit machining technology, in particular to an ultrasonic micro-pit machining device. The device solves the problems that an existing micro-pit machining technology islimited in application range, complex in machining process, high in machining cost, poor in machining continuity, low in machining precision and long in machining period. The ultrasonic micro-pit machining device comprises a horizontal workbench, a rectangular block-shaped supporting seat, a transverse supporting rod, an ultrasonic machining head, a time control switch and an ultrasonic generator,wherein the ultrasonic machining head comprises a circular-tube-shaped protective sleeve, a variable amplitude rod, a supporting disc, a piezoelectric transducer, a disc-shaped knife rest and a puncher pin, the input end of the ultrasonic generator is connected with the output end of an alternating current power supply through the time control switch, and the output end of the ultrasonic generator is connected with the input end of the piezoelectric transducer. The ultrasonic micro-pit machining device is suitable for machining a cylinder sleeve type friction pair.

Description

technical field [0001] The invention relates to a micropit processing technology, in particular to an ultrasonic micropit processing device. Background technique [0002] When processing cylinder liner friction pairs, it is usually necessary to process micro pits (tiny pits) with a certain size, shape and arrangement on the inner surface of the cylinder liner to improve the surface tribological properties of the friction pair and reduce the friction of the friction pair And wear, improve the performance and life of the friction pair. Under the existing technical conditions, the micropit processing technology mainly includes electrochemical mask processing technology, diamond indentation technology, surface shot peening technology, laser surface texturing technology, etc. Practice has shown that the existing micropit processing technology has the following problems due to its own limitations: 1. The problem of electrochemical mask processing technology is that the range of p...
