摘 要 [资料来源:http://www.THINK58.com] 零件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 [资料来源:http://think58.com] 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 [版权所有:http://think58.com] 工阶段以保证加工精度。基准选择以后钢板弹簧吊耳大外圆端面作为粗基准,以后钢板弹簧吊 [资料来源:http://think58.com] 耳大外圆端面与两个工艺孔作为精基准。主要加工工序安排是先以后钢板弹簧吊耳大外圆端面 [来源:http://think58.com]
互为基准加工出端面,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 [来源:http://think58.com] 艺孔定位加工其他孔与平面。整个加工过程均选用组合机床。 [资料来源:http://www.THINK58.com]
