摘　　要：针对为了保证双螺杆挤出压片机轴承座/盖与机筒的同轴度,避免了传统将机筒与轴承座/盖组立加工影响产品互换性及加工效率方法,引进新的加工工艺理念,采用工艺销为基准一次性加工出端面与轴承孔,不组立即可保证轴承座/盖轴承孔的加工精度进而满足图纸要求,并提高产品零部件的互换性,提高加工效率缩短制造周期。In order to ensure the coaxiality between the bearing seat/cover and the barrel of the twinscrew extruder,avoid the traditional method of processing and assembling the barrel and the bearing seat/cover,which affects the product interchangeability and processing efficiency,this paper introduces a new processing technology concept,which uses the process pin as the benchmark to process the end face and bearing hole at one time.Without assembly,the processing accuracy of bearing seat/cover bearing hole can be guaranteed,so as to meet the drawing requirements,improve the interchangeability of product parts,improve the processing efficiency and shorten the manufacturing cycle.
