Specific embodiment
From Fig. 1, Fig. 2, Fig. 3, Fig. 4 as can be seen that it is a kind of can 6 points of scroll chucks of clamping workpiece, its three groups of clamp system by chuck body 1 and on chuck body constitutes, and constitutes scroll chuck.Drive device, sliding block 3 etc. are additionally provided with chuck body 1.The concrete composition structures such as chuck body 1, drive device, sliding block 3 are identical with prior art, repeat no more.
It is characteristic of the invention that：The each group of clamp system is provided with a claw body 4 and and swings claw 8, and the claw body 4 is arranged on the sliding block 3 of chuck body by mounting screw 5,9 and T-nut 2.The swing claw 8 is arranged on claw body 4 by bearing pin 6.The swing T-shaped structure of claw 4, is made up of arched arm and a staight shank, and the afterbody of staight shank has the circular hole for installing bearing pin 6, and the lateral surface two ends of arched arm are provided with two tooth fourths 7.As shown in Figure 5, Figure 6.Fig. 5 is the top view of the swing claw of stretching workpiece inner circle.Fig. 6 is the top view of the swing claw for clamping excircle of workpiece.Swinging claw 8 can swing around bearing pin 7, make two tooth fourths 7 and the absorption surface on arched arm.Three groups the three of clamp system swing 6 points of claw completely and absorption surface, realize 6 points of clamping workpiece.
Further, the claw body 4 is rectangle structure, is being provided with two stage steps, is machined with bearing pin counterbore and screw counter bore in two stage steps respectively, as shown in Figure 7.Claw body 4 is arranged on the sliding block 3 of chuck body 1 by mounting screw long 9, short mounting screw 5.As shown in Figure 2, Figure 4 shows.
Further, the mounting screw long 5 coordinates on the sliding block of chuck body through bearing pin counterbore with T-nut 2.Bearing pin counterbore has two effects：One is that, for installing fixed pin shaft, another effect is mounting screw long through bearing pin counterbore, mounting screw long 9 and short mounting screw 5 together, claw body is fixed on the sliding block of chuck body, can so save assembly space.
Further, the afterbody of claw body 4 is provided with raised a, tail protrusion on the staight shank afterbody correspondence claw body of swing claw 8, on bearing pin 6 upwards.
As shown in figure 8, the tooth, 7 is cylindrical, and end is with teeth and protrudes swing claw.With workpiece of holding.Tooth fourth 7 is arranged in the tooth fourth hole that the swing arched arm of claw 8 is provided with by bolt 11.
As shown in figure 9, the bearing pin 6 is in hollow tubular.The bottom of bearing pin 6 is arranged in the upper pin counterbore of claw body 4, and top coordinates through the circular hole of staight shank afterbody on claw 8 is swung with claw is swung, and the top of bearing pin 8 is additionally provided with a back-up ring 10.The mounting screw long 9 coordinates through back-up ring 10, hollow bearing pin 6 with T-nut 2, and claw body and swing claw are fixed on the sliding block of chuck.Swing claw after installation, play but can not be swung around bearing pin up and down by the limitation of back-up ring 10.Amplitude of fluctuation is subject to the raised limitation of claw body tail section.The amplitude of fluctuation of claw is swung to limit.
The claw body is with mounting screw and T-nut on the sliding block of chuck body.The installation site of claw body and direction, according to clamping the different and different of workpiece inner circle and excircle of workpiece.Bowlder is as shown in Figure 1 and Figure 2 in stretching workpiece.During clamping excircle of workpiece as shown in Figure 3, Figure 4.Radially inside and outside moved in the case where the drive device of chuck body drives, drive claw body and swing the movement such as claw to clamp and unclamp workpiece.
When three groups of clamp systems are used for bowlder in stretching workpiece, as shown in Figure 1, Figure 2, Figure 5, lateral surface of the claw 4 in arched arm is swung（It is also outer convex globoidal）Two ends are installed by two tooth fourths 7.Bowlder in stretching workpiece, claw body 4 and swing claw 8 are under drive device driving, moved along the from-inner-to-outer of sliding block 3, when a tooth fourth 7 on swing claw 8 touches workpiece, claw 8 is swung to be rotated around bearing pin 6, until two tooth fourths 7 all with absorption surface, swing claw 8 and stop swinging stretching workpiece.Three of final three groups of clamp systems swing 6 points of claw completely and absorption surface, realize 6 points of clamping workpiece.
When three groups of clamp systems are used to clamp excircle of workpiece, as shown in Fig. 3, Fig. 4, Fig. 6, lateral surface of the claw 4 in arched arm is swung（It is also inner concave arc surface）Two ends are installed by two tooth fourths 7.Claw body 4 and swing claw 8 are under drive device driving, from outer to inner moved along sliding block 3, when a tooth fourth 7 on swing claw 8 touches workpiece, swing claw 8 and rotated around bearing pin 6, until two tooth fourths 7 all with absorption surface, swing claw 8 and stop swinging stretching workpiece.Three of final three groups of clamp systems swing 6 points of claw completely and absorption surface, realize 6 points of clamping workpiece.
