- ZQ350型減速機(jī)機(jī)體加工工藝及銑機(jī)__畢業(yè)設(shè)計(jì)說明書ABSTRACT
The title of graduation project is "the design of ZQ350 reducer body of technological procedure and assembly technology clamp "there are two main tasks: The first is the design of technological procedure of box parts ,and the second is the design of assembly technology clamp of box parts .During the design of technological procedure, the first step is to analysis the parts according to production program, materials of parts and the other requirements ,and to determine the manufacture form of rough;the followed is to select rough and precise in accordance with the principles of reference, then deciding the process routes ,and detetmining the final programme by the Integrated Comparison and analysis ; the final is to determine mechanical allowance, process dimension, blank dimensions, cutting parameters and the basic working hours. In the design of part of assembly technology clamp, the first is the determination of location programme,choosing location reference reasonably and analysising error in accordance with the characteristics of every process. if the location reference does not coincide with design reference , we must work out the dimension chain;the followed is the calculation of the cutting force by the characteristics of the processing .considering all the factors ,we will design the clamping programmes reasonably and calculate the clamping force, and design the clamp finally. Key words: reducer; technological procedure; assembly technology clamp
