Side thrust pins

GN 715

w = movement of pin
F = side thrust [N]
  initial thrust = F₀
  end thrust = 1,1 x F₀
a₂-a₁= clamping range for
  workpiece
x = distance center line - thrust point
  at w / 2
  x₁ for highest thrust point (a₁)
  x₂ for lowest thrust point (a₂)

l₀ = Distance end stop -
  bore of thrust bush
l₀ = l_m + x
  l_m = average length of (I_max. + I_min.) / 2
  workpiece

For contact points (workpiece height)
between a₁ and a₂ a value for x has
to be used lying between x₁ and
x₂ (interpolation).

By observing the above values the full movement of the side thrust pin is available to cover the tolerance of the workpiece.

For inserting the side thrust pins the use of mounting tool GN 715.1 or spanner GN 713.1 is recommended.

Eccentric bushes GN 715.2 are a tooling accessory for GN 714 / GN 715.
They enable a precise optimum setting of side thrust pins This allows an adjustment to l₀to accommodate for instance a larger tolerance range on a workpiece.
