The length metering grating 15 lower ends eccentric disc 30 of ining succession is carved with 180 ° sulculus round nut 31 in the dish, length metering grating 15 can be around the central shaft Rotate 180 of angular measure grating 1 °, when rotating to some angles, and can be fixing by nut 31.Luminous point can move around along guide rail 16 by counter 14, angular measure grating 1, plane polar coordinates of length metering grating 15 the two composition, and it and outgoing laser beam 17 are combined into a three-dimensional measurement coordinate.The laser-bounce that reflection diaphragm 13 will incide on the blade 11 is put on to plane utmost point dirt, any one reflection light point has reflected the coordinate relation of the blade 11 tested flank of tooth on polar coordinates, move and rotate the luminous point reception simultaneously by counter 14, make to receive aperture aligning reflection light point on it, so just obtain the parameter of tooth angle plane in three-dimensional coordinate.
The vertical platform 7 of level, horizontal cross platform 8 have been formed one group of horizontal portraitlandscape moving guide rail.On guide rail, installed can 90 ° of rotations rotating base 9, the cutter adjusting bracket 10 of ining succession above and can load different-diameter, the different flank of tooth, it is when laser beam is got on blade 11 reference fields or beaten on blade 11 tooth angle faces, and the three-dimensional coordinate that the three-dimensional coordinate of adjusting blade tooth is determined itself and instrument coincides.But adjusting bracket 10 is finely tuned with the vertical and horizontal level that adjusting screws nut 12 blade.
Cutter tooth tooth plane is not an ideal plane owing to add each factor affecting in man-hour, and the efficient of laser-bounce is low, therefore needs a high reflection diaphragm of desirable reflectivity and is attached on the tooth angle face.In order to prevent to come off, this reflection diaphragm is developed into and has high magnetic, and its reflection diaphragm is made by the Nd-Fe-B permanent magnetic material.
Shown in the chromosome 3, light path turnover pipe 6 inserts light path turnover base 5 by sleeve pipe 19, facing to laser beam incident hole 20 deflecting prism 21 is housed in the sleeve pipe bottom, in the upper end of sleeve pipe prism table 24 is housed, lens 23 are contained in the bottom of prism 24 and are fixed by lens tight loop 22, in the upper end of prism table 24 deflecting prism 25 is housed, lens 26, tight loop 27, lens 28 and fastening adjustment circle 29 are housed respectively from left to right on the prism table right side.Prism 21 is transferred 90 ° simultaneously to the reflection of the laser beam of incident, the course of laser beam is along sleeve pipe 19, lens 23, scioptics 26 and 28 shine on the reflection diaphragm 13 after 90 ° of deflecting prism 25 inside surface generation total reflections turnovers, get on the plane polar coordinates of being made up of angular measure grating 1 and length metering 15 by the reflection of reflection diaphragm 13. Lens 26 and 28 are combination focusing systems, as required, laser beam can be assembled, and focal length is adjustable at 400～1500mm.
Be that example illustrates concrete measuring method now to survey garden saw blade tooth angle.Back knife face according to blade shown in Figure 1 is P1, and rake face is P2, and crest top land is P3.Supposing that the radial direction with blade is an X-axis, tangentially is Y-axis, axially is the Z axle, and with near the denticle direction be positive dirction.With the garden saw blade cutter adjusting bracket 10 of packing into, adjusting screws nut 12, make blade adjustment to horizontal level, crown point alignment with tested tooth, at this moment, the vertical platform 7 of horizontal cross platform 8 and level all is in the zero-bit amount, flank of tooth P1 sticks reflection diaphragm 13 in the cutter that regulates, light beam reflects by reflection diaphragm, receive luminous point by counter 14 and aim at reflection light point this moment, the angular measure grating 1 that length metering grating 15 is being connected goes to horizontal position, the display zero clearing, rotate length metering grating 15, angular measure grating 1 is counted at this moment, when luminous point is injected into the luminous point reception by counter 14, with regard to the raster count of automatic cut-off angular measure, the number of display demonstration is the value of P1 angular measure grating 1, then, allow luminous point receive and return starting point along guide rail 16 by counter 14, the display zero clearing, traveling light spot receives by counter 14, receives automatic cut-off rolling counters forward when counting 14 apertures when luminous point enters, and the long raster values that show this moment is the value of P1 length metering grating.In like manner record the value of P2, P3.
According to the program disk that provides, starting microcomputer, demonstration and printer, three groups of data inputs of P1, P2, the P3 microcomputer internal diameter that records is crossed each space angle that the microcomputer computing just can show and print the blade tooth angle.Just represented that as the α among Fig. 13 P1, P2 intersection are projected on the yoz plane about the angle between the Z axle, by that analogy, all can obtain.
Its measuring principle is as follows: according to P1, P2, the P3 tooth plane of correspondence shown in Figure 1, should there be definite coordinate parameters on each tooth plane in three-dimensional.Know that the plane equation expression formula by true origin is how much by space analysis:
AX＋BY＋CZ＝0 （1）
When these plane normal direction cosine were known, formula (1) can be rewritten as:
Xcosα＋ycosβ＋Zcosγ＝0 （2）
Plane equation for P1, P2, P3 tooth plane can be expressed as:
Xcosαk＋ycosβk＋Zcosγk＝0 （3）
Wherein: k=1,2,3 represents P1, P2, P3 tooth plane respectively
If the coefficient of (3) formula is represented with matrix method:
By (4) formula as can be known,, just can release angle between each flank of tooth that needs by equation (3) as long as we measure 9 coefficients in (4) formula, the projection angle of flank of tooth intersection, and the angle between intersection and the intersection etc.
For example, instrument when measuring left tooth, the measurement coefficient of (4) formula can derive following formula:
Wherein:

Know by formula (5), (6), (7), as long as blade diameter determines that record the angular measure grating 1 of P1, P2, P3 and the reading value of length metering grating 15 simultaneously, all of this tooth need angle all can calculate.
For example:
P1 and P2 flank of tooth intersecting lens L(1,2) about the projection on the yoz face of Z axle clamp angle: be α 3 among Fig. 1, through (3), (4), (5) formula derives and draw:
In the reading value and blade diameter substitution (8) formula with the P1 that measures and P2 length metering grating and angular measure grating, can calculate α 3, each α angle value shown in of in like manner all publishing picture at last.
The utility model has the advantages that simple in structurely, with low cost, adopt computer processing data, easy to operate.
