L-705 Hinge Line Alignment System

L-705 Hinge Line Alignment System Hamar Laser’s Hinge Line Alignment System has been a proven performer in the aerospace industry for many years. In fact, the first hinge line system Hamar Laser delivered revolutionized the industry by reducing an 8-hour job, requiring eight workers and four the¬odolites, to one that took only two workers less than an hour to complete. In addition, accuracy was significantly higher and the results were consist¬ently repeatable. Currently, several aircraft builders are using this align¬ment system to accurately align hinge-pin bushings in tooling fixtures and vertical and horizontal stabilizers.

L-705 Laser Fits Into Standard Optical Tool Fixtures

The L-705 Laser has been designed with a standard aerospace tooling diameter of 2.25" (57.15 mm). The centering of the laser beam to the housing is controlled to extremely tight tolerances, usually less than .0005" (.013 mm). Built-in micrometers on the back of the laser control the angle adjustment of the laser beam. These two features eliminate the steering fixture and a reference target, making the task of aligning large floor assembly jigs fast and accurate.

T-271 Virtual Target Reduces Costly Fixturing

Hamar Laser Instruments has developed the world’s only virtual target (T-271) that is used for conventional, through-type bushings and spherical-bearing hinge line bushings. It is considered a virtual target because it functions as if it were in the actual center of the respective bearing without actually being inside it. No matter what attitude the spherical bearing is in, the target center readings are accurate. This reduces costly fixturing needed with conventional hinge line alignment methods.

R-1307 Readout

The Model R-1307 Readout supports both wireless targets, such as the A-1519, or local (cabled) targets. It is available with a radio frequency of either 900 MHz or 2.4 GHz ISM band. The R-1307 can be used as the primary readout or as an additional readout to copy position data captured by another R-1307.
