Design of the milling machine for transmission fork of transmission(horizontal)
Summary: This text mainly introduces the parameters and structure principle of X62W type horizontal milling machine for fork of transmission, with wheel and spring chuck design calculate, choice and use of cutter and electrical machinery, preparation method course and choices of different standard component of part. X62W type horizontal milling machine for transmission fork of transmission is one set of semi-automatic horizontal mill special plane. It regard current X62W type miller as the half automatic on that stir the fork special airplane. The workpiece fixing with its sipindle hole. The spolting spindle is placed in disc worktable. Its working process is: anticipate on the artificial- automatic position- automatic clamp- automatic milling, after milling unclamped the work piece automatically and taken down the workpiece by the operator. Use this kind of special airplane works can overcome the current X62W type miller much disadvantage such as big labor strength bi, low productivity. The X62W type horizontal milling machine for fork of transmission’s work tempo is 20piece every minute. And have the work safety, dependable, construction tightly packed, circulate steady, product quantity stability, operation and maintenance simple etc. various advantages. The reconstructing of X62W type horizontal milling machine for fork of transmission would getting application effectively, and will obtain the good result, It will creats evidence economic performance for the business enterprise at the need of the premise bottom.
