Summary of the invention
The present invention will solve current Water conservancy diversion core mandrel owing to not having machining benchmark and plane of orientation, and appearance curved surface adds cannot locate and cause the problem that cannot process man-hour, provides a kind of Water conservancy diversion core mandrel adhered processing method.
The adhered processing method of Water conservancy diversion core mandrel of the present invention, carry out according to the following steps:
One, be cuboid by Water conservancy diversion core mandrel Milling Process;
Two, the empty cutter groove of Milling Process Water conservancy diversion core mandrel upper curved surface, then milling both sides, respectively processes Φ 6 dowel hole at Water conservancy diversion core mandrel two ends;
Three, Special Fixture for Machining: by Water conservancy diversion core mandrel upper curved surface dimensioned mutually close-fitting recessed appearance curved surface with it, then Φ 6 dowel hole at the empty cutter groove in the both sides of milling fixture and two ends, match with the Water conservancy diversion core mandrel after step 2 Milling Process;
Four, Water conservancy diversion core mandrel and fixture are passed through two Ф 6 straight pin orientation assembles, use glue Water conservancy diversion core mandrel and fixture to be bonded as one, shape is cuboid;
Five, after bonding, by the fixture clamping that assembles on flat-nose pliers, use CNC milling machine to be got rid of by the redundance of Water conservancy diversion core mandrel the latter half, obtain adding working drawing Water conservancy diversion core mandrel;
Six, by the mode of heating, Water conservancy diversion core mandrel is separated from fixture, finally complete processing.
Beneficial effect of the present invention:
The present invention adopts adhered processing method to complete the processing of Water conservancy diversion core mandrel smoothly, workpiece after machining, molded line precision is within 0.02mm after testing, by the exploitation of the adhered processing method of Water conservancy diversion core mandrel, will use for reference its process program solve that other are complex-shaped, cannot the processing of parts of clamping.
