The specific embodiment
As shown in Figure 1, 2, 3 for the structural representation of collet of the present invention.The present invention is a double-stage type collet, the canned paragraph 14-0 and the plurality of elastic sheet that is positioned on the canned paragraph 14-0 one end circumference that comprise tubular, described plurality of elastic sheet is one-level flexure strip 14-1 and secondary flexure strip 14-2, has one-level in the outside of described one-level flexure strip 14-1 and compresses conical surface 14-3 (referring to Fig. 5); Have in the relevant position, the outside of described secondary flexure strip 14-2 that another one-level compresses conical surface 14-3A and secondary compresses conical surface 14-4 (referring to Fig. 6), one-level compresses conical surface 14-3, another one-level, and to compress conical surface 14-3A be consistent on axial location.
Described one-level flexure strip 14-1 and secondary flexure strip 14-2 alternately arrange along the end of canned paragraph 14-0.One-level flexure strip 14-1 and secondary flexure strip 14-2 add up to even number.For making the chucking power equilibrium, clamping point disperses, and I and II pressurizes simultaneously, makes workpiece add man-hour, avoids skidding, and can clampedly not be out of shape again.Also can make three grades or more multistage clamping.
As Fig. 4, each one-level, the secondary that adopt clamping ring 13 to be used on each flexure strip compress pressurization simultaneously on the conical surface, so that this collet is clamped, described clamping ring 13 is sleeved on each flexure strip 14-1,14-2 outside (Fig. 7-10), the one-level compacting ring 13-1 of the inboard of clamping ring 13 and secondary compacting ring 13-2, by moving right, the one-level on each flexure strip, secondary compress and begin pressurization (Fig. 7,8) on the conical surface simultaneously.Compress the position (Figure 10) that secondary that conical surface 14-3 (Fig. 9) and described secondary compacting ring 13-2 be in secondary flexure strip 14-2 compresses conical surface 14-4 when one-level compacting ring 13-1 is in one-level on the one-level flexure strip 14-1, finished pressurization.
As Fig. 6,8,10, on the internal diameter of described secondary flexure strip 14-2, be the boundary to compress conical surface 14-4 right positions C place corresponding to secondary, the internal diameter of the right-hand member of this position C is greater than the internal diameter of this position C left end.Purpose is to guarantee that the place of compressing on one-level flexure strip 14-1 compresses conical surface 14-3 for one-level, corresponding to the clamping of D place; The place of compressing on secondary flexure strip 14-2 compresses conical surface 14-4 for secondary, corresponding to the clamping of C place.C on secondary flexure strip 14-2 sentences right internal diameter and strengthens (for example machining with electric spark), interferes when having avoided compressing, and still keeps the clamping of C place.
