Sheet Beam Generator Alignment System for Fuel Particle Velocity Measurement System for Automotive Engines

摘要

The present invention discloses a sheet beam generator alignment device for a fuel particulate velocity measurement system of a vehicle engine. The disclosed invention includes: a beam receiver 10 connected to a laser generator 1, into which a circular laser beam is incident; One side is connected to the beam receiver 10, the hollow articulated link 20, the beam is moved along the inside; A sheet beam generator (2) installed at the other side of the articulated link (20) to convert the circular beam into a planar shape and irradiate the cylinder block (3) of the engine; A pair of upper and lower plates 31 and 32 spaced apart from each other by predetermined intervals that support the sheet beam generator 2 from below; A spring (33) installed at three of each corner between the upper plate and the lower plate (31,32) to elastically support the upper plate (31); A pivot pin 34 installed at the remaining corner between the upper plate 31 and the lower plate 32 to connect the upper plate 31 to the lower plate 32 so as to be rotatable at a predetermined angle; A pair of vertical micrometers 41 of which a top is vertically installed at a corner of a lower portion of the lower plate 32 so as to be connected to the upper plate 31 to adjust the height of the upper plate 31; And a horizontal micrometer 42 installed horizontally at one corner of the upper plate 41 to adjust a horizontal rotation angle of the upper plate 31 with respect to the lower plate 32.
