Abstract
The present invention relates to a kind of processing method of Helicopter Dome support member, first step preprocessing；Positioning fixture is arranged on jig installation position 1 by second step, and 1mm surpluses are stayed in the rough turn region in addition to intermediate press plate 2 and jig installation position 1；3rd step lays down intermediate press plate 2, installs four side clamping plates 4, fixes part 3 from outside, remaining unprocessed region in rough turn, smart car, the finish-milling first step；Part is connected by the sagging hole that the 4th step is processed by second step with the cooperation of respective screw hole on positioning fixture with positioning fixture, lays down side clamping plate 4, the remaining area of smart car second step smart car, remaining position of the processing part 3 in addition to lightening core；5th step installs outer end clamp plate 5 in the outer face of part 3, rough mills, lightening core at finish-milling 5.Clamping during processing is rationally solved the problems, such as, frock and Digit Control Machine Tool resource, and substantial amounts of turnaround time have been saved, with good effect.
Description
Technical field
The invention belongs to field of machining, it is related to a kind of processing method of Helicopter Dome support member.
Background technology
Rectification cover support members are the important component of helicopter lift system, and blank is forging part and accessory size is larger
(diameter 600mm thickness 230mm), was to use many machine toolings in the past, because clamping difficulty causes processing, stable conditions are poor, institute
It is not high with processing efficiency, and occupancy lathe and frock resource are more.
The content of the invention
The technical problem to be solved in the present invention：Asked caused by clamping is difficult when conventional helicopters rectification cover support members are processed
Topic.
Technical scheme：A kind of processing method of Helicopter Dome support member, comprises the following steps,
The first step, preprocessing, part 3 is tapered tubular structure, it is necessary to carry out turn-milling cutting, clamping to its surfaces externally and internally
Before, end face is first processed at three-axis machining center, milling positioning endoporus bores a dowel hole；
Second step, positioning fixture is arranged on jig installation position 1, part 3 is fixed into clamping by intermediate press plate 2,
Ensure that blank outer surface and the area above of inner surface intermediate press plate 2 can be processed, it is rough turn to remove intermediate press plate 2 and jig installation position 1
Region in addition, stays 1mm surpluses；
3rd step, lays down intermediate press plate 2, installs four side clamping plates 4, fixes part 3 from outside, rough turn, smart car, finish-milling
Remaining unprocessed region in the first step, including the sagging hole that 5 are next step smart car front clamp；
The cooperation of respective screw hole is by part on 4th step, the sagging hole processed by second step and positioning fixture and positions
Fixture is connected, and lays down side clamping plate 4, the remaining area of smart car second step smart car, remaining position of the processing part 3 in addition to lightening core；
5th step, outer end clamp plate 5 is installed in the outer face of part 3, is rough milled, lightening core at finish-milling 5.
Beneficial effects of the present invention：Clamping during processing is rationally solved the problems, such as, frock and Digit Control Machine Tool resource has been saved,
And the substantial amounts of turnaround time.
Brief description of the drawings
Fig. 1 is second step clamping schematic diagram of the present invention, wherein, 1 is positioning fixture, and 2 be intermediate press plate, and 3 be part.
Fig. 2 is the 3rd step clamping schematic diagram of the invention, wherein, 4 be side clamping plate, and 5 be hole of sinking.
Fig. 3 is the 4th step clamping schematic diagram of the invention, wherein, 6 be outer end clamp plate, and 7 be lightening core.
Embodiment
With reference to Figure of description, installation and working method to the present invention are described.
The first step, as shown in figure 1, part 3 be tapered tubular structure, it is necessary to carry out turn-milling cutting to its surfaces externally and internally,
Clamping, clamping is fixed by positioning fixture and intermediate press plate 2 by part 3, it is ensured that blank outer surface and inner surface intermediate press plate 2 with
Upper region can be processed, the rough turn region in addition to intermediate press plate 2 and positioning fixture installation site 1, stay 1mm surpluses；
Second step, installs four side clamping plates 4, lays down intermediate press plate 2, fix part 3 from outside, as shown in Fig. 2 slightly
Remaining unprocessed region in car, smart car, the finish-milling first step, including the sagging hole that 5 are next step smart car front clamp；
3rd step, the sagging hole processed by second step by screw tightening in corresponding screwed hole on positioning fixture, by zero
Part is connected with positioning fixture, lays down four side clamping plates 4, and the remaining area of smart car second step smart car processes part 3 in addition to lightening core
Remaining position；
4th step, as shown in figure 3, installing outer end clamp plate 5 in the outer face of part 3, is rough milled, lightening core at finish-milling 5.
