Solving problems of alignment – The Micro Alignment Telescope Displacement Micrometer Crossline graticule Focusing micrometer Erector lens Displacement micrometer Cover glass Micrometer block Focusing lens Objective lens Since the late 1930s Taylor Hobson has sold thousands of alignment telescopes to industries throughout the world. The Micro Alignment Telescope is used to set and check alignment, squareness, straightness, flatness, parallelism, verticality and level. With its wide range of accessories the Micro Alignment Telescope forms a unique and comprehensive system for solving alignment...

Principles of alignment The basic measurement principles available with the Micro Alignment Telescope system are alignment, squareness, flatness, autocollimation and autoreflection. The Micro Alignment Telescope generates a straight line of sight from zero to infinity. This forms the basic reference from which all measurements are taken. To measure squareness a penta prism is used to deviate the straight line through exactly 90 degrees. A similar rotating pentaprism is used to generate a plane for flatness measurement. The Telescope is designed to allow autocollimation and auto-reflection, providing...

Alignment checks (externally and internally) Typical applications • Alignment of periscope bearings using the main bearing in the hull of the submarine as the datum • Alignment of diesel engine bearings and boring bar • Checking straightness of gun barrels using a digital MAT and sliding a target on a sledge along the inside of the gun barrel and its rifling. Diesel engine alignment (shown here using CCTV system 137-2161-01) Typical equipment used Micro Alignment Telescope (112-2582 or 112-2583) Adjusting Bracket (112-645) Bore Fixture (112-1168) Mounting Sphere (112-376) Right Angle Eyepiece...

Horizontal and vertical measurement Typical applications • The line of sight of the Alignment Telescope is parallel to its mechanical axis. Hence by using an electronic level it can be set truly horizontal. If two lines are set horizontal then they are parallel in at least one direction. • Platforms for satellites: two platforms are set first in line then (using optical squares) set parallel to each other. • The Alignment Telescope can be set both horizontally & truly vertically – this feature can be used to great effect in the nuclear industry. Typical equipment used Micro Alignment Telescope...

Straightness measurement Engine Room Bulkhead Telescope Typical applications Engine L.O.S. fouls bulkhead here • The large focusing range of the alignment telescope makes it ideal for checking long machine slideways • The rails in a submarine torpedo tube need to be set straight • Propellor shafts are getting increasingly long and the Alignment Telescope is ideal for this long distance bearing alignment work Datum Target Scale Typical equipment used Propellor shaft alignment Micro Alignment Telescope (112-2582 or 112-2583) or Digital Micro Alignment Telescope (112-3389) Horizontal Base (112-656)...

Digital Alignment Telescope (code 112-3389) Using high resolution CCD technology and dedicated software, the Alignment Telescope can be digitised to automatically calculate the displacement from a set datum to ensure fast set up and repeatable readings as well as digitally outputting the result. This is particularly useful on large alignment projects such as aircraft jigs or large machine tools since a single operator can make measurements and adjustments along the construction or fixture while the target is displayed on the monitor. (see further details on page 10). Micro Alignment Telescope...

the Micro Alignment Telescope System Select your alignment kit from these accessory items: To use the Micro Alignment Telescope you will need to select from a range of accessories. Should you need any advice on the precise accessories and components necessary, contact Spectrum Metrology or your local Taylor Hobson outlet. Note: The Micro Alignment Laser System (112-3331) is not used with these accessories (see page 15) An adjustable tripod is available as an alternative to the unimount (code 112-4942 & adaptor 112-4943)

Micro Alignment Telescope accessories Digital CCD Accessory (code 137-2160-01) (connects to any Taylor Hobson Telescope) Available as an accessory upgrade for existing Micro Alignment Telescopes in the field, a high resolution CCD system with software automatically senses the centre position of the dedicated CCD targets then calculates the displacement from a set datum to ensure a fast set up time with repeatable readings, as well as digitally outputting the result. This is particularly useful on large alignment projects such as aircraft jigs or large machine tools since a single operator can...

Micro Alignment Telescope accessories Mounting the telescope Adjusting Bracket (code 112-645) Provides a fine azimuth and elevation adjustment for sighting the Telescope, used with a Horizontal Base or Bore Fixture. Horizontal Base (code 112-656) Used for mounting the Adjusting Bracket onto either the Plain, Flange or Adjustable Cup. When used on flat surfaces (plain cup), two fence pins provide a sideways location. Plain Cup (code 112-472) Locates the Mounting Sphere on the Horizontal Base with its centre 73.5 mm (2.9 in) from the base of the Cup. Flange Cup (code 112-471) Locates the Mounting...
