Ball and Socket for an Adjustable Contouring Fixture

A magnetic head is precisely positioned during lapping so that the apex of the contour coincides with the head's gap.

Heads are mounted on fixture 10 so that the gap is located at points A and A' (Figs. 1 and 2). Points A and A' are established as tangent points for two chords passing through point B of the fixture.

To allow alignment between the apex of the head and the head's gap, R(1) of the fixture represents a spherical radius of a ball and socket joint generated from point A around which the head (not shown) may be rolled to adjust relative position of the apex on the contour at the part and gap of the head. This concept makes it possible to maintain the relative position between the apex of the contour and the gap.

R(2) is a spherical radius which allows the locking screw to be rotated within a reasonable amount of tolerance, while with the mating washer. The mating washer to R(2) will allow the assembly to be secured into position without stresses forcing it to move. R(3) represents the radius size required for the head contour. Additionally, R(3) is the radius size of a lapping cup which is used to lap the head.
