A laser etching processing device for the inner wall of an internal combustion engine cylinder

Abstract

The invention discloses a cylinder body inner wall laser etching device. The cylinder body inner wall laser etching device comprises a laser device, a machine tool and a control part. The laser device comprises a laser device body, a light path system and a focusing head. The machine tool comprises a working table, a machine frame and a drive mechanism. A workpiece clamp is installed on the working table. The light path system and the focusing head are arranged on the machine frame. The drive mechanism drives the focusing head to conduct feeding and rotating two-dimensional movement relative to a cylinder body. An industrial personal computer serves as a main part of the control part and controls an encoder and a sound and light power supply at the same time so that pulse lasers can be accurately controlled to acting on all positions of the inner wall of the cylinder body. On the basis of the laser texturing technology, the cylinder body inner wall laser etching device is high in pulse laser micro-pit etching speed and high in efficiency.

Description

technical field [0001] The invention belongs to laser processing equipment, in particular to equipment that uses high repetition frequency pulsed laser to focus on the inner wall surface of a cylinder to form discrete etching micropit processing. Background technique [0002] The cylinder block and piston ring are one of the most important friction pairs in the internal combustion engine, which directly affects the service life and performance of the internal combustion engine. And the performance depends largely on the anti-wear performance of this pair of friction pairs. At present, the inner wall of the automobile cylinder at home and abroad is mainly ground by sand bars. In the 1980s, the laser quenching technology for the inner wall of the cylinder was produced to improve the wear resistance of the cylinder. However, laser quenching cannot improve the friction and lubrication conditions of the cylinder-piston friction pair. , it is difficult to achieve the comprehensiv...

At present, the inner wall of the automobile cylinder at home and abroad is mainly ground by sand bars. In the 1980s, the laser quenching technology for the inner wall of the cylinder was produced to improve the wear resistance of the cylinder. However, laser quenching cannot improve the friction and lubrication conditions of the cylinder-piston friction pair. , it is difficult to achieve the comprehensive goal of fuel saving and emission reduction
