The specific embodiment
Below in conjunction with accompanying drawing a kind of little axial workpiece dislocation type screening plant of the present invention and using method thereof are described in further detail:
As shown in Figure 1, little axial workpiece dislocation type screening plant of the present invention mainly comprises screen plate 1, following screen plate 2 and pressing plate 5, wherein, design has some through hole 3a of going up on the last screen plate 1, shape is determined according to screened part, the gap of the monolateral 0.05mm of having when its width requirement part falls can enter smoothly with the assurance part, and can limit feature rocking at axial direction.Length direction then determines that according to composite factors such as the full-size of part, last through hole 3a chamferings last screening is of a size of D, and as shown in Figure 3, last screen plate 1 is used to screen the rejecting length dimension and exceeds poor part.Two ends respectively be provided with a projection at following screen plate about in the of 2, be used to locate screen plate 1, after last screen plate 1 is packed into, under the effect of stirring handle 6, can horizontally slip in the screen plate 2 down, and the same design in the corresponding position of through hole 3a has lower through-hole 3b on following screen plate 2 and the last screen plate 1, upper and lower screen plate 1,2 cooperates has formed time screening size E, as shown in Figure 3, its shape and size determine that according to the factors such as following tolerance of screened part following screen plate 2 is used to screen the part that the rejecting length dimension is lower than allowance below nominal size.Last screen plate 1 is packed into down behind the screen plate 2, and two ends install pressing plate 5 additional, limiting the moving range of screen plate 1, and setting-in circular magnet 4 in the pressing plate 5, be used to move into place screen plate 1 on the location, back.
