Specific implementation mode
As shown in Figure 1 and Figure 2, a kind of positioning device for flange processing described in the embodiment of the present invention, including：Work
Mounting base 3 is fixed on the table top of platform 1, mounting base 3 totally nine is distributed in nine grids shape, and as shown in Figure 2, Figure 4 shows, mounting base 3 is wrapped
Include 32 two centralized positioning axis 31, collet parts；Centralized positioning axis 31 is multidiameter shaft, and the big lower end in the upper end is small, in multidiameter shaft
External splines 311 is machined on the periphery of upper end, external splines 311 is uniformly cut into three parts, and each part contains three teeth；
Screw 34 passes through and is furnished with stopping shim 33 at the middle part of multidiameter shaft, and stopping shim 33 includes gasket body 331,332 liang of flanging
Part；Four notches 321 are uniformly processed on collet 32, there are one small gaps 322 for processing between the notch 321 of two, left side；Such as
Shown in Fig. 1, unilateral hold-down mechanism 5 is located at the outside of mounting base 3, including pressure plate 53, mandril 52, guide holder 51；Pressure plate 53
It is connect in end hinge with mandril 52, mandril 52 is oriented to by guide holder 51, and guide holder 51 is fixed on workbench 1 and passes through hinge
Plate 54 is movably attached to the middle part of pressure plate 53, compression bar 55 is housed, the height of compression bar 55 is adjustable (referring to Fig. 6, figure on pressure plate 53
7)；As shown in Figure 1, bilateral hold-down mechanism 2 is fixed between two neighboring mounting base 3, including jacking rotary axis 21, press strip 23,
Small axis 22 is installed, 23 middle part of press strip is emptied and is rotatably arranged on small axis 22 after the head cutting of jacking rotary axis 21
(referring to Fig. 8, Fig. 9).
This processing unit (plant) is positioned by the major diameter of spline, ensures that connecting hole position and splined central are good same when part processing
Axis degree and quick-clamping, the work in-process heart and drilling machine obtain good processing effect when processing, and meet the stability of batch machining；
Workpiece flange realizes the positioning in upper and lower directions by mounting base, passes through external splines on centralized positioning axis and flange lower part
The positioning of circumferencial direction is realized in internal spline cooperation, while external splines is processed at 3 points and the internal spline of flange lower part is connected,
While realizing precise positioning, it is more convenient to pick and place flange, improves working efficiency.
Empty and be rotatably arranged on small axis in the middle part of press strip so that when bilateral clamp system work stress completely with it is small

Need the flange processed as shown in Figure 10, Figure 11, it is now desired to process four holes 41 and one in its disk
Flange 4 to be processed is placed in mounting base by aperture 42, the rotation of internal spline and external splines fitting limitation flange；
Unilateral hold-down mechanism first acts, and mandril acts on pressure plate, pressure plate rotation, and the compression bar for being installed on pressure plate compresses method
Blue one end；
It is acted after bilateral hold-down mechanism：Jacking rotary axis first rises swings 90 degree again, declines again later so that press strip is by two
A adjacent flange screw, since press strip can move in small angle range around small shaft rotation, will not cause method during compression
Blue impression and destruction, actual good positioning effect.
It after the positioning for realizing flange, is processed and is portalled in the disk of flange by numerical control head, processing waste material is lacking
It is leaked out at mouth and small gap.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, any made by repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
