Abstract
A laser machining apparatus for machining the splitting slot on master bearing seat for the cylinder body of engine is composed of a mechanical system and a YAG solid laser cutting system. Said mechanical system consists of cylinder body and its machine frame, and bench and its machine frame. Said bench comprises a numerally controlled X-Y bench, an X-axis bench and a Y-axis bench with a laser cutting head driven by a rotary cylinder to rotate by 180 deg.
Description
technical field The invention relates to special laser processing equipment for cracking grooves of main bearing seats of engine cylinder blocks. Background technique The traditional processing method of the main bearing seat of the engine cylinder block is separate processing, that is, the bearing cover and the bearing seat (the bearing seat and the cylinder block are integral castings) are cast separately, and then the joint surfaces are milled separately, and the bolts are processed separately. hole. The traditional process has low production efficiency, high manufacturing cost and poor assembly accuracy. The cracking processing technology of the main bearing seat of the engine cylinder is to first process the initial cracking grooves A and B on both sides of the center of the main bearing seat 1 hole of the integrally cast and semi-finishing cylinder block, and then use the cracking special equipment to process the bearing seat holes. The normal stress applied to the...
