摘要
本次设计是对汽车转向横拉杆右接头零件的加工工艺规程及一些工序的专用夹具设计。汽车的转向横拉杆右接头零件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。基准选择以右接头M52螺纹孔作为精基准,以不加工外圆作为精基准作为精基准。主要加工工序安排是先以镗削M52螺纹孔做为其他面的定位基准,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车床。

ABSTRACT
This design is on the vehicle steering levers of joint parts processing technology of the right procedures and some process of special jig design. The car turned to horizontal bars right joint parts processing surface is flat and main hole. The processing technology, it is known that guarantee the principle in the plane of the machining accuracy than guarantee hole machining accuracy easy. So this design follow the principle of face first hole. And in the plane of the hole processing clear divided into rough machining and intensive processing stage in order to ensure that the processing accuracy. Benchmark choose the right joint M52 threaded hole as pure benchmark, with the benchmark as fine processing round as fine a benchmark. Main processing process arrangement is first to boring cut M52 threaded hole as the other position datum, again with end face positioning processing technology hole out. In the subsequent process in addition to the individual with the process are face and technology hole hole and other plane positioning processing. The whole process are chosen for ordinary lathe.
Keywords The car turned to lever connectors Processing technology special fixture
