Silicon Valley Automation- How it works

How it Works General Description Each AFAB™ alignment hardware kit consists of:- a threaded adjustment nipple (1),- a keyed nipple adjuster (2), and- a socket head screw (3)The main advantage of this alignment method is the application of the holding force precisely at the center of an adjustment point. The holding force is applied by screw (3) through a keyed nipple adjuster (2) and alignment plate (4) to nipple (1) and base plate (5). Application of the holding force at the center of each adjustment point totally eliminates stresses in the material (plates 4 and 5), providing that three, and only three AFAB kits are used. The second advantage of the method is the fact that tightening the screws does not change the results of the preceding alignment procedure. See "How it Works" Demo Note! Figures that illustrate the following description are dimensioned with alphabetic symbols. Their actual values are listed in tables located on catalog pages.
	How to use AFAB™ kits ? There are two ways the AFAB™ kits can be used. Usually the keyed nipple adjuster (2) is hidden inside material of the plate being adjusted (4) (see the drawing to the left). In some rare cases, however, the keyed nipple adjuster (2) can stick out of the plate (see the drawing to the right).
How to prepare your parts ? Regardless of the application method it is necessary to prepare three threaded through holes B x D for three AFABs.Alphanumeric, symbolic dimensions shown below are tabularized in the catalog pages.
Usually the keyed nipple adjuster is hidden in a counter bore A x C.	If the keyed nipple adjuster can stick out, the thickness of the plate can be reduced to dimension D.	The preparation of thebase plate is independentof the application method,and requires three threaded holes E in a material of minimum thickness F.
Adjustment range. Theoretically the adjustment range of an AFAB™ kit is from 0 to h1max. It is however strongly recommended to leave always a small gap between the plate being adjusted and the base plate. The gap should grow if AFAB™ kits are installed farther from the edge of the plate being adjusted.
	These two plates should never touch each other! As the result of this requirement it is not possible to achieve 0 (zero) as a lower adjustment range in practice.Other dimensions: h2min , h2max , and h3max show variousaspects of engagement between the threaded adjustment nipple and a keyed nipple adjuster, and can be disregarded by a designer implementing AFAB™ kits.
