GN 817.3 / Indexing Plungers for Precision Locating, Plunger Cylindrical

Information

Indexing plungers GN 817.3 realize a reasonable priced precision locating when guide bushings DIN 172 / DIN 179 are used.
The precise location is, therefore, not dependent on the guide pin in the plunger, but on the accuracy of the guide bushing (bore tolerance F7) and the plunger (tolerance h7). Both components are hardened and ground. It goes without saying that the bushing length also influences the accuracy of the positioning.
Type C is used for such applications where the plunger has to stay in its retracted position. To achieve this, the knob is rotated by 90° degrees after being retracted. A notch keeps the plunger in this position.

Construction and Assembly Instructions for Indexing Plungers GN 817.3 (Plunger Pin Cylindrical)

Two different plunger pin lengths l₁ are available for each indexing plunger diameter d₁.
The length l₃ must ensure that the plunger pin fully disengages, bushing length and plate thickness plus any gap can then be selected within certain margins.
For mounting bushings with tolerance n6, a hole with tolerance H7 corresponding to the external diameter is usually provided.
A selection of suitable guide bushings DIN 172 and DIN 179 is given below on.

Construction and Assembly Instructions for Indexing Plungers GN 817.5 (Plunger Pin Conical)

The length l₇ is determined by the penetration depth of the plunger pin into the cone of the bushing.
The length l₈ must ensure that the plunger pin fully disengages, bushing length and plate thickness plus any gap can then be selected within certain margins.
If engaged, the pin must have a minimum remaining stroke of 0.5 mm to make sure that the conical section of the pin is located without clearance in the cone of the guide bushing.
Two different plunger pin lengths l₁ are available for each indexing plunger diameter d₁ (see product table).
For a safe remaining stroke length: l₉ = l₁ - 0.5 mm
For mounting bushings with tolerance n6, a hole with tolerance H7 corresponding to the external diameter is usually provided.
A selection of suitable guide bushings DIN 172 / DIN 179 with cylindrical bore and guide bushings GN 172.1 / GN 179.1 with conical bore is given below on.
