Embodiment Construction

[0031] The following embodiments are given in conjunction with the accompanying drawings to further describe the device of the present invention in detail.

[0032] Referring to Fig. 4, a laser processing equipment for cracking grooves of engine block main bearings includes a mechanical system and a YAG solid laser cutting system. It is characterized in that the mechanical system is composed as follows:

[0033] Above the workbench frame 4, there is a two-axis numerically controlled workbench that can translate along the X and Y axes (the X axis is the direction perpendicular to the drawing surface, and the Y axis is the horizontal direction of the drawing surface). Laser cutting head rotary oil cylinder 9 is arranged. The laser cutting head 2 is connected with the rotary oil cylinder 9 through the support sleeve 11 .

[0034] The engine cylinder block 14 is accurately positioned above the cylinder body frame 3 through the positioning pin 12 and the positioning oil cylinder ...

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 [0001] The invention relates to special laser processing equipment for cracking grooves of main bearing seats of engine cylinder blocks. Background technique [0002] 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. [0003] 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 norma...
