The direction phase that time laminating in face 112, first side 320 just should set with the first side 320 during the digital cuttings of grinding given shape
Overlap.Such Curve guide impeller, can improve the clamping efficiency to blade: described fixture is main when the situation of similar the following stated
For rectangular blade and triangular blade are carried out clamping (fixture the blade of main clamping should be according to the concrete feelings of blade manufacturing enterprise
Depending on condition, it is to illustrate as a example by rectangular blade and triangular blade herein), wherein the clamping times of triangular blade is more,
The clamping times of rectangular blade is less, at this moment, i.e. guarantees to make described second when design and manufacture the first movable location-plate 300
When side 330 and positioning table terrace 112 are fitted the first side 320 just with the first side 320 (cutter during grinding triangular blade
Location, sheet side plane 310) (as shown in Figure 4, wherein blade 500 is a triangular blade, should to answer direction initialization to coincide
In figure, the direction residing for the first side 320 forms an angle with positioning table terrace 112 shape, on blade 500 at the bottom of outwardly location
The side of plate 110 is face to be ground), quickly at positioning plate 110 before this makes it possible to conveniently when clamping triangular blade
Upper installation is had good positioning the first movable location-plate 300.When wanting clamping rectangular blade, then to the first movable location-plate 300 He
Second movable location-plate 400 move, rotate (as it is shown on figure 3, wherein blade 500 is a rectangular blade, this figure
In direction residing for the first side 320 vertical with positioning table terrace 112, the side of outwardly positioning plate 110 on blade 500
Face is face to be ground).
As a example by the triangular blade shown in clamping Fig. 4, the using method of above-mentioned fixture is illustrated below.First, assemble
Good fixture, tightens first after being fitted with positioning table terrace 112 the second side 330 of the first movable location-plate 300 and can live
Carry out the screw threadeded on the bar hole of dynamic location-plate 300 with the hole 111, respective threaded location selected, and press under blade
Mechanism 200 and the second movable location-plate 400 are substantially installed and are adjusted to preferable position；Then by triangular blade 500
One side be close to the first movable location-plate 300 blade side location plane 310, hereafter rotate the second movable location-plate
400 (radius of gyration of the second movable location-plate 400 can be entered by the installation site in screw bar hole in latch spoon portion 420
Row sum-equal matrix), make the circular arc chamfering face 411a of blade side locating detent point 411 tangent with the another side of triangular blade 500 and press
Tightly, then tighten and carry out screw thread even with the hole 111, respective threaded location selected on the bar hole 421 of the second movable location-plate 400
The screw connect, thus the location that complete paired blades is in the horizontal direction；Finally adjust piece under pressure 250 in blade press mechanism 200
Position and volume under pressure, thus downwards compress triangular blade 500, complete the clamping of diabolo blade 500.
