3rd step, First machining center is changed milling boring back side fixture, utilizes bent axle back side cutter machining crankshafts back outer circle, utilize motor hole essence cutter to process motor hole, utilize drill bit, the installing hole at the reamer machining crankshafts back side and motor installing hole, squeezing tapping screw thread;
4th step, utilizes second machining center to coordinate milling boring side fixture, utilizes wire rod quality milling instep plate, utilize various process tool to process periphery hole, squeezing tapping each hole screw thread;
5th step, utilizes honing head honing two cylinder holes to processing criterion.
The mould assembling face processed described in wherein said step 2 and the crankshaft hole at the back side, oil pump axis hole, all first roughing of camshaft hole, then fine finishining once.
Described in wherein said step 2 when processing crankshaft hole, oil pump axis hole, the camshaft hole at mould assembling face and the back side, also the pin-and-hole around it, installing hole are machined simultaneously.
First the inventive method utilizes First numerical control machining center to join numerical control turntable, with blank precast piece first time Set and Positioning; Then the wire rod quality processing mould assembling face of First machining center is utilized, utilize rough boring cutter and fine boring cutter machining crankshafts hole, oil pump axis hole, camshaft hole and pin-and-hole, drill bit is utilized to process the installing hole of periphery, squeezing tapping each hole screw thread, simultaneously in machining crankshafts hole, oil pump axis hole, camshaft hole and pin-and-hole time, all first roughing then fine finishining once, makes each hole machined in mould assembling face complete like this; On First machining center, subsequently change milling boring back side fixture, utilize bent axle back side cutter machining crankshafts back outer circle, motor hole essence cutter is utilized to process motor hole, utilize drill bit, the installing hole at the reamer machining crankshafts back side and motor installing hole, squeezing tapping screw thread, by hole main for double-cylinder tank two sides, machine; Recycle second machining center and coordinate milling boring side fixture, utilize wire rod quality milling instep plate, utilize various process tool to process periphery hole, squeezing tapping each hole screw thread; Utilize honing head honing two cylinder holes to the processing criterion of cylinder holes.
Like this in whole process, only need clamping three times, just can complete the processing of double-cylinder tank, clamping times is few, and improve working (machining) efficiency, the error of simultaneously accumulating is little, so machining accuracy is high.
