工艺夹具类毕业设计课程设计目录 CA6140杠杆加工工艺及夹具设计本设计是CA6140杠杆零件的加工工艺规程及-些工序的专用夹具设计。CA6140杠杆零件的主要加工表面是平面及孔。-般来说,保证平面的加工精度要比保证孔的加工精度容易。因此,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孔的加工精度。基准的选择以杠杆 外圆面作为粗基准,以 孔及其下表面作为精基准。先将底面加工出来,然后作为定位基准,在以底面作为精基准加工孔。整个加工过程选用组合机床。在夹具方面选用专用夹具〖虑到零件的结构尺寸简单,夹紧方式多采用手动夹紧,夹紧简单,机构设计简单,且能满足设计要求。
关键词 杠杆零件,加工工艺,夹具,定位,夹紧
ABSTRACT
This paper is to design the craft processes of making the CA6140 lever spare parts and some specialized tongs in the process. The CA6140 lever spare part primarily processes the surface and bores. Generally speaking, to guarantee the accuracy of the flat surface process is easier than that of the bore. Therefore, this design follows the principle that surface first and then the bore, and definitely divides the process of flat surface and bore into coarse processes and precise processes to guarantee the bore processes. The basic choice is to consider 45 outside circle as rough basis and to consider 25 bore and its next surface as precise basis. The bottom is first processed out to be fixed position basis, and process the bore using the bottom as the precise basis. The whole processes choose the machine bed. In the aspects of tongs choosing, specialized tongs are used. In consideration of the simple construction size of the spare parts, clipping by hands is adopted. It is simple, and the organization design is simple, and can satisfy the design request.
Key Words Lever spare parts, craft proces , tongs, fixed position, tight clip
