The working method of big L/D ratio feedforward waveguide pipe processing device, works as follows：
1）Feeding
1.1）Aluminum pipe is clamped on the table by clamp assembly,
1.2）Fixture block position is adjusted by bolt, it is ensured that aluminum pipe is horizontal；The position that waveguide is finely tuned by adjusting block makes
The center of waveguide, the center of knife bar are in the same center line, it is ensured that machining accuracy when processing, if guide length mistake
It is long, driven fixture can be increased on the table, a waveguide using the clamping of multiple fixtures, effectively avoid in clamping process because
Micro-deformation caused by waveguide its own gravity.
2）Processing
2.1）Motor by drive active fixture rotation to drive aluminum pipe and driven fixture coaxial rotating, using it is multigroup from
Same waveguide is clamped in dynamic fixture, to effectively reduce the eccentricity of long straight waveguide when rotated, improves machining accuracy.
2.2）Stepper motor rotates a fixed angle, and lead screw is driven to rotate in the forward direction, and lead screw drives sliding block to advance, sliding block band
Moving knife bar advances, and knife bar enters inside feedforward waveguide, and the diameter of knife bar is identical as the internal diameter diameter of waveguide, while processing
It plays a supporting role, knife bar only moves in a straight line under the promotion of sliding block in process, therefore, it is possible to ensure that cutter head is being cut
Be not in eccentric phenomena when cutting, improve machining accuracy.Cutter head only waveguide in cutting itself is rotating, and cutter head does not revolve
Turn, the big situation of cutter head rotating eccentricity caused by knife bar is long is not present, therefore can be processed with higher precision, improves
Machining accuracy.
2.3）Stepper motor two is stretched out with dynamic cutter head, is cut, when being cut, stepper motor two is with moving knife
Head stretches out, and thus allows for cutting, and in cutting, cutter head is only along knife bar radial expansion, and without rotation, therefore cutter head will not
Big bias is generated, so as to cause high precision machining.
2.4）Stepper motor two is resetted with dynamic cutter head, and cutting for the first time is completed, and is completed cutting at one time rear blade and is resetted, at this time
Control stepper motor one acts again, and cutter head precession forward repeats to cut, until entire waveguide machines.
2.5）Repeat step 2.2）~ step 2.4）, the processing until completing entire feedforward waveguide；
3）Withdrawing
3.1）Out of service, band after the completion of entire manufacturing procedure of stepper motor two after stepper motor two is resetted with dynamic cutter head
Dynamic to reset to the end, stepper motor two stops after reset so that cutter head is locked, prevents cutter head malfunction during withdrawing from scratching
The waveguide inside pipe wall processed.
3.2）Stepper motor one is continuously run, and lead screw is driven to reversely rotate, and withdrawing is completed；Stepper motor one reversely rotates,
Knife bar band dynamic cutter head exits, and when exiting there is still a need for injection cutting fluid, on the one hand plays lubricating action, knife bar when preventing withdrawing
With waveguide inside pipe wall friction, waveguide is damaged, on the other hand utilizes cutting fluid to machined surface（It is exactly waveguide inside pipe wall）It is rushed
It washes so that the waste material remained in waveguide inside pipe wall is rinsed out, reduces waste material residual, reduces the work of follow-up cleaning process
Intensity.Waveguide is still rotating during withdrawing, the friction of knife bar and waveguide inside pipe wall when reducing withdrawing so that withdrawing is more
Add smooth, while also protecting machined surface.
4）The material returned
4.1）Motor stops rotating, unclamp adjusting bolt, unclamp adjusting bolt after can extract adjusting block out so that fixture with
Gap between waveguide becomes larger, convenient for taking out waveguide.
4.2）Fixture block is taken out, extraction feedforward waveguide finishes.
