设计简介
摘要
本次设计是对泥浆泵Y型管的加工工艺规程及一些工序的专用夹具设计，如镗夹具与钻夹具。泥浆泵Y型管的主要加工表面是平面及孔。由加工工艺原则可知，保证平面的加工精度要比保证孔的加工精度容易。所以本设计遵循先面后孔的原则。并将孔与平面的加工明确划分成粗加工和精加工阶段以保证加工精度。基准选择以Y型管双管口面端面作为粗基准，以单管口面端面与管身的基面作为精基准。主要加工工序安排是先以管身与3个管口端面为基准加工出端面，再以端面定位加工出工艺孔。在后续工序中除个别工序外均用端面和工艺孔定位加工其他孔与平面。整个加工过程均选用普通机床

ABSTRACT
This design is a Y-pipe mud process planning and fixture design some of the special procedures, such as boring and drilling jig fixture. Y-pipe mud surface is flat and the main processing hole. Known by the principle of processing technology to ensure precision plane precision than the hole to ensure easy. Therefore, this design follows the principles of the hole after the first plane. And a clear hole and surface processing is divided into roughing and finishing stages to ensure accuracy. Benchmark choose to dual port Y-tube as a coarse face with reference to a single face to face with the tube nozzle base body surface as a fine reference. Arrangement is the first major processing operations to control the body and the nozzle 3 end processing of the end for the benchmark, then processing the process end positioning holes. In addition to the follow-up processes are used outside of individual processes and process end processing of other hole hole location and plane. The whole process of general machine tools are used
