Title: Machining head of laser beam machine
Inventor: MORI ATSUSHI
IPC: B23K26/14
Filed: 1990-03-15
Abstract: PURPOSE:To construct an airtight room without using a transmission type optical part and to perform high-powered laser beam machining by condensing laser beams with a laser beam introducing means, passing it through an orifice and introducing it into a working head. CONSTITUTION:The laser beams 2 from a laser beam oscillator 1 are reflected by reflectors 3a, 3b and introduced by the laser beam introducing means into the working head. That is to say, the laser beans 2 which are reflected by the reflectors 3a, 3b and arrive at a parabolic mirror 4 being a condenser are condensed by a parabolic mirror 4 once to be brought into a focus 5, diverge again and are guided to a parabolic mirror 6 being a magnifying glass. The laser beams 2 guided by the parabolic mirror 6 are magnified by the parabolic mirror 6 and returned to the parallel laser beams 2 again. The paralleled laser beams 2 are condensed by the parabolic mirror 6 being a condenser and brought into a focus 10 on the surface of a workpiece 9. Consequently, it is possible to construct the airtight room only with a reflector profitable for high power and perform high-powered laser beam machining without using the transmission type optical part.

CONSTITUTION: A main combustion chamber 2 in a cylinder 1 is communicated with an auxiliary chamber 5 in a cylinder head 3 by a communicating hole 6. In a compression stroke, compressed air is forced from the main combustion chamber 2 through the communicating hole 6 into the auxiliary chamber 5 to form a forced stream 11 in the auxiliary chamber 5, whereby fuel 13 injected from a fuel injection nozzle 4 is mixed with air. In this case, a projection 17 is provided along the longitudinal axis on the peripheral surface of the communicating hole 6, and the projection 17 is formed like a trigonal pyramid in such a manner as to be increased in its size as it approaches from the main combustion chamber 2 to the auxiliary chamber 5.  Thus, a turbulent is caused in the interior of a forced stream 11 by the friction due to a speed difference between an approaching stream and a separating stream, whereby mixture of fuel 13 and air in the auxiliary chamber 5 is made better so as to improve combustion.
