Require to manufacture supporting copying apparatus, the diameter of little axle 13 according to above-mentioned corresponding component size technologies
D generally can take 30-50 millimeter, and the front end arc radius F of push rod 10 generally can take 20-30 millimeter,
Template left and right arc radius R1 and radius R2 makes after calculating according to aforementioned formula；
Step 2, lower base 4 is fixed on side tool post ram 3, little axle 13 is installed to upper pedestal 5
After on, then upper pedestal 5 is installed on lower base 4, adjusts screw rod 9 when noting installing, make lower seat
Body 4 adjust to as far as possible away from the workpiece centre of gyration with ensure follow-up feed time have enough adjustment amounts, tighten
Screw 6 makes upper pedestal 5 fix with lower base 4；Push rod 10 and disc spring group 12 and guide plate 11 are pacified
It is firm to fill；
Step 3, template 15 is fixed on boatswain chair 14, then boatswain chair 14 top is arranged on crossbeam
On 18 (first do not fix, treat follow-up adjustment), make template 15 enter between little axle 13 and push rod 10 (see
Fig. 2), at this moment push rod 10 holds out against template 15 under the effect of disc spring group 12, and makes template 15 with little
Axle 13 also keeps contact condition；
Step 4, to cutter process, workpiece 1 is fixed on platen position to be processed, starts lathe,
Adjust crossbeam 18 and the position of side tool post ram 3 up and down, until tool nose and workpiece 1 outer wall circular arc
Center above-below direction is coplanar, and makes the center of template 15 arc surface and the center above-below direction of little axle 13
Coplanar；Then left and right adjusts boatswain chair 14, and boatswain chair 14 moves left and right and will pass through little axle 13 and push rod 10
Drive side tool post ram 3 to synchronize to move left and right, according to the allowance situation of workpiece 1, cutter is adjusted to
Behind the suitable relative position of workpiece 1 centre of gyration, tighten crossbeam 18 puller bolt 19 above, make
Boatswain chair 14 is fixed with crossbeam 18, and now the right position of template 15 is also fixed；
Step 5, first side tool post ram 3 is moved up, make tool nose position be in the song of workpiece 1
On upper surface, face 2, start lathe and make work table rotation；Then side tool post ram 3 is moved down out
Beginning linkage feed, side tool post ram 3 is by the lower base 4 interfixed with it, upper pedestal 5 and little axle
13 and push rod 10 under the control of template 15, (i.e. template can be moved according to pre-set track
The arc surface 16 of 15), workpiece 1 will be processed needs by the cutter being arranged on side tool post ram 3 termination
Curved surface 2；After covering a cutter, then move side tool post ram 3 and make tool nose position be in workpiece 1
On upper surface, loosen but screw 6 of not exclusively dismantling, make upper pedestal 5 and lower base 4 relative motion,
Rotate adjusting screw rod 9, make lower base 4 move to workpiece centre of gyration direction relative to upper pedestal 5, long heavy
Hole 7 makes screw 6 have mobile space, now lower base 4 can drive the side tool post ram 3 that is secured to
Workpiece centre of gyration direction is moved, and reaches the purpose of feed, after the mobile suitable depth of cut, then tightens spiral shell
Nail 6, makes upper pedestal 5 and lower base 4 become again stationary state, then starts downward linkage motion cutting the second cutter,
So repeat, until by curved surface 2 overall processing of workpiece 1 to predetermined size.
