(2) after the workpiece upset, mill each face of lower convex platform, finish-milling A datum level, camber beam fixing hole end face medial surface mill leaf spring pin shaft hole end face, mill the inboard facade in two places;
(3) each face and each face and chamfering and tapping all around around the processing.
In the processing technology of above-mentioned cargo vehicle front overhang combination cast, in step (1), need be coarse positioning with the left surface of workpiece and 3 of bottom surfaces and 2 of upper sides, other establishes an adjustable support is the aiding support location, clamps with clamping tool, processes on vertical machining centre.
In the processing technology of above-mentioned cargo vehicle front overhang combination cast, need be in step (2) with the two diagonal bore location of each face of convex platform processed and workpiece, the two diagonal bore location of workpiece refers to two and is each face of convex platform that the diagonal angle is provided with, clamp with clamping tool, on vertical machining centre, process.
In the processing technology of above-mentioned cargo vehicle front overhang combination cast, clamping tool is a chute-type pressing plate clamping tool.
Beneficial effect of the present invention:
Adopt above-mentioned technical process, each procedure arrangement is reasonable, and the location clamps rationally distributed, is convenient to workpiece location and clamping, can guarantee the required precision of workpiece, the working (machining) efficiency height.
