Abstract
Systems and methods are provided for securement of parts. One embodiment is a method for securing a part during fabrication. The method includes forming an interference fit between a pin and a wall defining a hole, supporting a weight of the part with the interference fit, and rotating the part around an axis of the part while the weight of the part is supported.
Claims20
A method for securing a part during fabrication, the part having a weight, the method comprising:
- forming multiple interference fits between each of multiple pins and respective multiple undersized holes disposed at a surface of the part, wherein the multiple undersized holes are disposed such that centerlines of the holes intersect a neutral axis of the part;
- supporting at least a portion of the weight of the part with the multiple interference fits;
- adjusting a pulley system to compensate for differences in elevation between the multiple interference fits;
- removing the pins;
- and
- after removing the pins, drilling out the multiple undersized holes to a respective assembly diameter, wherein the assembly diameter is larger than a diameter of the undersized hole.
A method for securing a part during fabrication, the method comprising:
- supporting the part by inserting multiple pins in respective multiple undersized holes in the part, wherein the multiple undersized holes are disposed such that centerlines of the holes intersect a neutral axis of the part;
- adjusting a pulley system to compensate for differences in elevation between the multiple pins;
- surface treating a surface of the part while the part is supported by the multiple pins;
- removing the multiple pins;
- and
- after removing the multiple pins, drilling out the multiple undersized holes to a respective assembly diameter, wherein the assembly diameter is larger than a diameter of the undersized hole.
A method for securing a part during fabrication, the part having a weight, the method comprising:
- forming an interference fit between each pin of a plurality of pins and a corresponding plurality of undersized holes disposed at a surface of the part, wherein the plurality of undersized holes are disposed such that centerlines of the holes intersect a neutral axis of the part;
- adjusting a pulley system to compensate for differences in elevation between the plurality of pins;
- supporting weight of the part by the interference fit;
- surface treating the surface of the part while weight of the part is supported by the interference fit;
- removing the plurality of pins;
- and
- after removing the pins, drilling out the plurality of undersized holes to a corresponding assembly diameter, wherein each corresponding assembly diameter is larger than a corresponding diameter of each undersized hole.
