Embodiment
Below in conjunction with specific embodiment, the utility model is described further:
As described in Figure 1, airscrew pitch measuring instrument of the present utility model comprises the crossfoot 4 of pawl dish 2, pedestal 3, elongated rod shape, the perpendicular chi 5 of elongated rod shape.Its median claw dish 2 is fixed by the taper hole of its claw and screw propeller 1.Pawl dish 2 is three-jaw self-centering chucks, and the structure of claw is step.It has used existing lathe chuck technology, and according to requirements three-jaw length and height and plane link position etc. are optimized repacking, make the three-jaw of chuck increase the length of every layer of step, the quantity of increase step, to be applicable to the screw propeller of larger diameter.
As shown in Figures 2 and 3, pedestal 3 comprises lower surface 31, the upper surface 33 parallel with lower surface 31, connects the support 32 of upper surface 33 and lower surface 31.The lower surface 31 of pedestal 3 is fixing by bolt and pawl dish 2, and upper surface 33 is provided with a rotating disk 34.Rotating disk 34 and upper surface 33 are annular concentric structures.Wherein the Area Ratio rotating disk 34 of upper surface 33 is large, and rotating disk 34 is positioned at the top of upper surface 33.Rotating disk 34 is connected with upper surface 33 by bearing.Upper surface 33 is provided with the angle dial 331 with rotating disk 34 couplings.Angle dial 331 can be arranged on the interior ring of annular upper surface 33, also can be arranged on the outer shroud of upper surface 33.Angle dial 331 can be dismountable structure, can be also to be fixedly installed on upper surface 33.Rotating disk 34 is provided with the pointer 341 of orientation angle index dial 331.Also be provided with the fixed mount 35 of frame-shaped construction on rotating disk 34.Fixed mount 35 comprises two, is separately positioned on along the two ends of rotating disk 34 diameters.By the fixing crossfoot 4 of fixed mount 35.Crossfoot 4 is elongated rod shape, is carved with range on it.Crossfoot 4 adopts 304 stainless steel materials to be made, have stiffness high, from advantages such as heavy and lights.Can guarantee being horizontally disposed with of crossfoot 4 by two fixed mounts 35.Also be provided with adjusting bolt 36 on each fixed mount 35.Conflict or separate with crossfoot 4 by adjusting bolt 36, the fixing or adjusting position with crossfoot 4.For convenient fixing, crossfoot 4 is rectangular structure.Coordinate the fixed mount 35 of shaped as frame, fixed effect is better.In addition, also be provided with a pressing plate 7 between adjusting bolt 36 and crossfoot 4, by pressing plate 7, increase stress surfaces, prevent that direct acting High Voltage due to 36 pairs of crossfoots 4 of adjusting bolt from causing the distortion of crossfoot 4, accuracy is measured in impact.In addition, pressing plate 7 also can play the effect in determining.Due to fixed mount 35 symmetries, pressing plate 7 two ends are set just with fixed mount 35 two ends, flush, the mid point of pressing plate 7 is exactly fix midway point.As preferably, pressing plate 7 is to be fixedly connected with adjusting bolt 36, and pressing plate 7 and crossfoot 4 are according to the adjustment of adjusting bolt 36 and corrective action power.When adjusting two adjusting bolts 36 simultaneously, pressing plate 7 can apply acting force equably on crossfoot 4, makes crossfoot 4 and rotating disk 34 laminatings closer.The central point of the pressing plate 7 between two adjusting bolts 36, be provided with center line, the position of center line and the axis coinciding of rotating disk.This center line is used for recording the length that crossfoot is measured.
In Fig. 1, be provided with the perpendicular chi 5 of elongated rod shape at the other end of crossfoot 4.Be carved with range on perpendicular chi 5, fixing with crossfoot 4 by fixture 6.The structure of fixture 6 guarantees that crossfoot is vertical with perpendicular chi, increases the accuracy of measuring.Because perpendicular chi 5 needs the directly blade 11 of contact screw propeller 1, the long-term use can produce wearing and tearing, in the bottom of perpendicular chi 5, is provided with scriber 51.Scriber 51 contacts with screw propeller 1 while being used for measuring the pitch height, and also will mark radian on blade 11 surfaces of screw propeller 1 when degree of making an arc, so scriber 51 employing alloys make, with good hardness and the abrasion resistance that reaches.In addition, scriber can be changed, and prevents the problem that the measuring accuracy that causes due to long-term wearing and tearing reduces.
As shown in Figure 4, fixture 6 is column structure, and it comprises the first clamping part of clamping crossfoot 4 and the second clamping part of the perpendicular chi 5 of clamping.The second clamping part comprises along post is high and runs through the duct 61 of fixture 6 and penetrate to duct 61 bolt 62 from the fixture side.It is fixing with fixture 6 by bolt 62 that perpendicular chi 5 passes duct 61.Adjust the elasticity of bolt 62, can regulate the perpendicular displacement of chi 5 in duct 61.The first clamping part is included in the fixture side and forms the recess 63 that holds crossfoot 4 and the adjusting portion 64 that moves adjusting recess 63 sizes along the screw thread of fixture 6.Recess 63 and crossfoot 4 form fit.Adjusting portion 64 is set on columned fixture 6 by screw thread, by adjusting portion 64, utilizes screw thread that crossfoot 4 is fixed on fixture 6, makes crossfoot 4 mutually vertical with perpendicular chi 5, guarantees the data precision of measuring.Adjusting portion 64 comprises the nut that is enclosed within on fixture 6 screw threads, perhaps has the bolt of through hole.Bolt passes internal thread duct and the crossfoot 4 of the second clamping part and conflicts.As preferably, crossfoot 4 broad ways run through a duct, and this duct is identical with the duct xsect of fixture, perpendicular chi 5 parts are passed the duct of fixture, a part is passed the duct of crossfoot, and at the axis in the duct take crossfoot, is the scale initial point, marks this scale initial point on the surface of crossfoot., because crossfoot is vertical with perpendicular chi, in the position of the corresponding crossfoot of the center line of pressing plate 7, can read and need the value of measurement point apart from disk axes.
The installation method of this measuring instrument is as follows:
1, fixing screw propeller, make the taper hole of screw propeller upwards, and keep the screw propeller horizontal equilibrium.
In this step, by stationary installation, screw propeller is fixed, the taper hole aperture of screw propeller is vertical with ground level, opening upwards, screw propeller rough balance.Simply, by visual each blade that can observe screw propeller rough balance whether.Keep the screw propeller rough balance to be convenient to follow-up Installation and Measurement.
2, the taper hole clamping of claw and the screw propeller by the pawl dish, be fixed on the pawl dish on screw propeller.
Select suitable scroll chuck according to screw propeller taper hole diameter, the taper hole clamping of claw and screw propeller by the pawl dish, and whether coincidence loss is stipulated with measuring the fixed middle effect of slide calliper rule check.
3, pedestal is fixedly mounted on the pawl dish.
The rotating disk of test rotating basis is guaranteed its flexible rotating in 360 degree scopes, and with surveyor's staff, checks whether the pedestal installation meets the levelness requirement.
4, crossfoot is put into fixed mount, will erect chi by fixture and be fixed on the crossfoot other end, keep perpendicular chi vertical ground, and the locking adjusting bolt, the level of maintenance crossfoot.
Crossfoot penetrates in two fixed mounts of rotating disk, when an end of crossfoot is given prominence to the fixed mount certain distance on request, crossfoot is compressed with pressing plate by adjusting bolt, after crossfoot fixes, perpendicular chi is installed, is unclamped the screw between perpendicular chi and crossfoot, scriber contact paddle, the rotation crossfoot also stops in predetermined angle position, reads the pitch numerical value of diverse location on perpendicular chi.
The foregoing is only the preferred embodiment of explaining the utility model, not the utility model is done any formal restriction.All any modification or changes of the relevant the utility model of doing under identical utility model spirit, all must be included in the category of the utility model intention protection.
