FIELD: machine building.SUBSTANCE: part with one-sided access for fastening with locating is made mainly of a plate and contains locating and fastening elements in the form of at least two through holes located in one or parallel planes. Profile of holes represents an order of circular radial n projections-cavities, which are similar and symmetrical relative to their middle parts, the maximum and minimum distances of which to the hole axis are located on concentric circles; at that, one of holes is made with n?2, and the other one with n?3, where n=2, 3, 4, 5? - number of projections-cavities of normal row of figures.EFFECT: simplification of the design; reduction of manufacturing cost and prime cost of the assembly; improvement of manufacturability of the design and improvement of consumer and service performance of the product.11 cl, 25 dwg |
