Processing machine one machining center of composition, it is characterised in that concrete processing comprises the steps:
1, wheel hub is placed on the work top of First lathe, and wheel hub is blocked, specifically by the first cylinder frock
Position is mechanical coordinate: on the work top of X=350mm, Y=-303 mm, then that wheel hub blank is fixing by pin-and-hole location
In the first cylinder frock, using the processing of Φ 16 alloy corrugated milling cutter, its processing cart wheel hub scope is that X-direction is all processed, and Y is anti-
To for 220mm, processing rear surface roughness is 12.5 mm, blows off scrap and takes off workpiece.
One spoke of this wheel hub is positioned at the negative direction of Y-axis.
2, the wheel hub after step 1 is processed is placed on the workbench on second lathe, by the second cylinder work
Wheel hub correspondence is blocked by dress, i.e. mechanical coordinate is: on the work top of second lathe of X=350mm, Y=-303 mm, so
After the wheel hub blank dextrorotation after step 1 is processed is turn 90 degrees, wheel hub blank is fixed on the second cylinder frock
On, and use Φ 16 alloy corrugated milling cutter to process, the wheel hub scope of processing be X-direction be 0, Y-direction is all processing, processing
The position that in one upper semi-circle, step 1 is not worked into, the most finished wheel hub is not above the part of board work top
(semicircle), processing rear surface roughness is 12.5 μm.
3, the 3rd cylinder frock is revolved turnback according to step 1 inverse position hour hands, be fixed on by the 3rd cylindrical support dish
On the work top of the 3rd lathe.And by the 3rd cylinder frock, the wheel hub blank after step 2 is processed is blocked, concrete position
Put on the work top that coordinate is X=350mm, Y=-303 mm, then 90-degree rotation counterclockwise for wheel hub blank, and by the 3rd
Cylinder frock is locked, use Φ 16 alloy corrugated milling cutter processing, the range of work be X-direction be 0, Y positive direction is all processed,
Processing step 1 and 2 unprocessed positions in the middle of a upper semi-circle, processing rear surface roughness is 12.5 μm.
4, use the applicant invention wheel hub special machine, this processing machine include platen face 1, backing plate 2,
3-360 rotary cylinder 3, chassis the 4, the 4th cylinder frock prop up support plate 5 and cylinder frock 6.On chassis 4, symmetry is equiped with four 6-90
Degree rotary cylinder 7, the 4th cylinder frock 6 is fixed on the 4th cylinder frock and props up on support plate 5, and the 4th cylinder frock is propped up support plate 5 and installed
Having on chassis 4, chassis 4 is supported by 3-360 degree rotary cylinder 3, and 3-360 degree rotary cylinder is fixed on the 4th lathe by backing plate 2
Work top 1 on.Particular location is mechanical coordinate X=350mm, on the 4th work top of Y=-303 mm, then will pass through
Step 1,2 and the 3 wheel hub blank after processing is placed on the 4th work top, by pin-and-hole and the 4th cylinder tool locating, and 4
6-90 cylinder-pressing makes wheel hub be pressed abd fixed in the 4th cylinder frock, uses Φ 10R5 alloying pellet cutter finish-milling, 360 degree of rotary pneumatics
Cylinder working width when O spends is 250mm, and after machining, then rotary cylinder dextrorotation turn 90 degrees, and processes a upper semi-circle and works as
The position that in, sequence is not worked into, after machining, sequence on this rotation turnback one upper semi-circle of processing counterclockwise of rotary cylinder
The position not being worked into, window surface all machines, and machines rear rotary cylinder and returns to 0 degree, takes off workpiece, i.e.
?.
It is an advantage of the current invention that:
Use this method processing cart wheel hub, the round jitter values that dynamic balancing is processed under the rotating speed of 8000 revs/min by traditional method
0.6-0.9mm becomes present 0.05-0.2mm, thus improves production efficiency, adds profit.Reach with Product Precision in season
Having arrived customer requirement, processing rear surface coarse is 3.2 μm, detects dynamic balancing run-out tolerance≤0.2mm.
