Detailed description of the invention
From Fig. 1, Fig. 2, Fig. 3, Fig. 4, can find out, a kind of scroll chuck that can 6 clamping work pieces, it is made up of chuck body 1 and three groups of clamp mechanism being arranged on chuck body, forms scroll chuck. On chuck body 1, be also provided with drive unit, slide block 3 etc. The concrete composition such as chuck body 1, drive unit, slide block 3 structure is identical with prior art, repeats no more.
Feature of the present utility model is: described each group clamp mechanism is provided with a claw body 4 and and swings claw 8, and described claw body 4 is arranged on the slide block 3 of chuck body by mounting screw 5,9 and T-nut 2. Described swing claw 8 is arranged on claw body 4 by bearing pin 6. Described swing claw 4 is T-shaped structure, is made up of arched arm and a staight shank, and the afterbody of staight shank has the circular hole that bearing pin 6 is installed, and the lateral surface two ends of arched arm are provided with two tooth pieces 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 of clamping work pieces cylindrical. Swinging claw 8 can swing around bearing pin 7, and two tooth pieces 7 on arched arm are contacted with workpiece. Three 6 of claws of swing of three groups of clamp mechanism contact with workpiece completely, realize 6 clamping work pieces.
Further, described claw body 4 structure that is rectangle, it is provided with two stage steps, is processed with respectively bearing pin counterbore and screw counter bore, as shown in Figure 7 in two stage steps. Claw body 4 is arranged on the slide block 3 of chuck body 1 by Chang'an cartridge screw 9, short mounting screw 5. As shown in Figure 2, Figure 4 shows.
Further, described Chang'an cartridge screw 5 coordinates on the slide block that is arranged on chuck body with T-nut 2 through bearing pin counterbore. Bearing pin counterbore has two effects: the one, for fixed pin shaft is installed, another effect is to make Chang'an cartridge screw through bearing pin counterbore, Chang'an cartridge screw 9, together with short mounting screw 5, is fixed on claw body on the slide block of chuck body, can save like this assembly space.
Further, described claw body 4 afterbodys are upwards provided with a projection, and the tail protrusion on the corresponding claw body of staight shank afterbody of swing claw 8, is arranged on bearing pin 6.
