【正文】 hell process features are: the structure of plex shape。 uneven wall thickness and stiffness is low。 based on the enterprises ability to actively adopt advanced process technology and equipment, and constantly enhance their level of technology. Gearbox shell machining process design should follow the following basic principles: The selection of processing equipment The principle of selection adopted the principle of selection adopted the principle of bining rigidflexible, processing each horizontal machining center is located mainly small operations with vertical machining center, the key process a crank hole, cylinder hole, balancer shaft hole Highspeed processing of highprecision horizontal machining center, an upper and lower noncritical processes before and after the fourdimensional highefficiency rough milling and have a certain adjustment range of special machine processing。 gearbox shell machining process design the main content Gearbox shell plex structure, high precision, arge size, is thinwalled parts, there are a number of high precision plane and holes. Engine block machining process characteristics。 Fine reference base Refined the base of this box for the engine block parts, the general use of side two sales for a full range of uniform benchmarks, For the longer automated production positioning. In the gearbox shell of the process, we have adopted to the side, bottom and the spindle hole positioning, in the processing center on the process. Machining Processing Stages and processes of the arrangements Often a part of many apparent need for processing, of course, the surface machining accuracy are different. Processing of high precision surface, often after repeated processing。 semifinishing phase of the engine block machining In order to ensure the accuracy of the middle of some important surface processing, and arrange some semifinishing operations, will be required accuracy and surface roughness of the surface of the middle of some processing to plete, while demanding the surface of semifinished, to prepare for future finishing。 secondary processing Secondary processing such as small surface screw holes, you can finish of the major surface after the one hand, when the workpiece deformation process little impact at the same time also reduced the rejection rate。 make proper arrangements for secondary processes Make proper arrangements for secondary processes such as product inspection process,in part roughing stage,the key process before and after processing,spare parts all the processing has been pleted,should be appropriate arrangements. Stage of processing division,has the following advantages:First,it can take measures to eliminate the rough workpiece after the stress,to ensure accuracy。again,first roughing
