Optimización del proceso de rectificado de asientos esféricos en las cañerías de combustible de alta presión para motores de energía eléctrica

Abstract

The objective of this Project is to optimize the rectifying process of spherical seats, by designing and building a high precision mechanism for replace a former process. In the first chapter a description of how the company is making the rectifying process, maintenance schedule of the electrical motors, and failure detections in fuel lines. It’s proposed as a solution, the design of a rectifying machine that will works with tree types of sand paper, in order to choose the best. In the second chapter the design of the mechanism is performed, taking into account factors such as: speed, power, efforts and standardized elements, to determinate the proportions of each element in the mechanism. Having identified these elements thought mathematics calculus, design a mechanical plan, specifying dimensions and geometric tolerances. The third chapter contains an estimate of costs in order to find the total value of the project, through cost research of materials, human labor, machinery and equipment. Furthermore, is performed an experimental analysis with different sandpapers at different speeds in order to choose the most optimal grinding process, it´s project also includes conclusions, recommendations, an operation sheet, and maintenance sheet. Ending attached annexes contains invoices, tables, machine’s photographs, and mechanical planes.
