With G hole behind half finish-milling of exhaust rocker arm, G hole before half finish-milling, G hole behind the finish-milling, G hole before the finish-milling, the empty cutter in G hole after the boring, the empty cutter in G hole before the boring, the thick F hole of boring, the axis system of the machining tool of nine road manufacturing procedures of right boring F hole and F Hole chamfering is installed in one to have on each station of rotary table of a plurality of stations, the peace position fixture of rocking arm processing all is installed on each station of rotary table, like this, on the clamping station of rotary table, carry out the clamping location of rocking arm, rotary table rotates, the workpiece of this clamping gone to process on the station of oilhole centre bore axis system before the first road manufacturing procedure is bored, on the clamping station, carry out simultaneously the clamping of workpiece again, after to be processed the finishing, rotary table rotates, the workpiece that processes first procedure then behind brill the station of oilhole centre bore axis system process, so, workpiece once just can be finished G hole behind half finish-milling of rocking arm at clamping on the clamping station of rotary table, G hole before half finish-milling, G hole behind the finish-milling, G hole before the finish-milling, the empty cutter in G hole after the boring, the empty cutter in G hole before the boring, the thick F hole of boring, nine road manufacturing procedures of right boring F hole and F Hole chamfering, the error that minimizing brings because of the workpiece multiple clamping, improve the machining accuracy of piston, and, No. one time clamping just can be finished nine road manufacturing procedures, thereby also can alleviate the labour intensity of workman's operation, enhance productivity.
Structure of the present utility model can be specially:
Rotary table is a kind of oil pressure rounding table, and this oil pressure rounding table is the oil pressure rounding table of CH3-800-10 for day model of dish board.
The structure of the positioning fixture of rocking arm processing can be specially:
Anchor clamps comprise clamping device and positioner, clamping device is a kind of pneumatic gripping, positioner comprises alignment pin and two limited blocks; rocking arm is located by alignment pin with the E hole; spacing by limited block at the H of rocking arm face and A face, and the E hole end surface by pneumatic gripping with the rocking arm clamping and positioning on anchor clamps.
Like this, by these anchor clamps with the intake rocker clamping and positioning, thereby be convenient to finish the processing of workpiece.
Structure of the present utility model can also further be specially:
Also comprise water tank, water tank is around the bottom that is installed in bed piece.
Like this, water tank is installed in the bed piece bottom, thereby utilizes the space of bed piece bottom, water tank just needn't take other space, reduces the waste in space, processing site, and, also make the mounting arrangements of processing machine more orderly.
Second special machine of exhaust rocker arm of the present utility model also comprises protective cover and drip tray, protective cover is looped around G hole axis system behind half finish-milling, G hole axis system before half finish-milling, G hole axis system behind the finish-milling, G hole axis system before the finish-milling, the empty cutter axis system in G hole after the boring, the empty cutter axis system in G hole before the boring, the thick F hole axis system that bores, right boring F hole axis system, the periphery of F Hole chamfering axis system, drip tray is positioned at the below of protective cover and the top of water tank, and drip tray has delivery port, the top of water tank that is positioned at the below of delivery port correspondence has open ports, is coated with screen pack on the open ports of this water tank.
Like this, one protective cover is installed, is made the processing bits that in process, splash to be blocked in the protective cover, prevent to process bits and splash everywhere and destroy the cleaning of processing site in the periphery of the system of processing of this special machine.And drip tray is used to be collected in and adds the water that spills man-hour, is back in the water tank recyclingly after drip tray is collected, and the screen pack on the water tank is used for filtering the processing bits, make processing bits and moisture from, water then reflow tank is recycling.
In sum, the utility model has following advantage compared to prior art: with the empty cutter in G hole before the empty cutter in G hole after G hole, the boring before G hole, the finish-milling behind G hole, the finish-milling before G hole, half finish-milling behind half finish-milling of exhaust rocker arm, the boring, slightly the axis system of machining tool that bores nine road manufacturing procedures of F hole, right boring F hole and F Hole chamfering is installed on the processing stations of a rotary table correspondence, thereby a clamping just can be finished ten road manufacturing procedures of rocking arm, the error that minimizing brings because of the workpiece multiple clamping, can improve machining accuracy, reduce labour intensity, enhance productivity.
