The specific embodiment

Below, by reference to the accompanying drawings the utility model processing clamper for motor stator vehicle is described further:

As shown in Figure 1, 2, a kind of processing clamper for motor stator vehicle comprises scroll chuck 1, mandrel 4 and automatically controlled and PCU (not shown).

Scroll chuck 1(is commercially available) formed by disk body 2 and claw 3, disk body 2 is vertically placed, be provided with ladder hole I 5 at the center of disk body 2, on an end face of disk body 2, be provided with uniformly three claws 3 around ladder hole I 5, claw 3 is connected with slide block (not shown) in being arranged on disk body 2 by screw, so that claw 3 can clamp under the drive of slide block, decontrol.

It is fixing by screw and disk body 2 that mandrel 4 passes the ladder hole I 5 of disk body 2.

Shown in Fig. 1-4, the front end of mandrel 4 is a disk 6 that vertically arranges, and in the center of circle of disk 6 front end faces one projection is arranged, and the shape of disk 6 front end faces and the interior hole shape of workpiece 13 are complementary.

Be formed with adpting flange 7 around mandrel 4, circumference along adpting flange 7 is provided with three groups of ladder hole II 8, screw is fixed on adpting flange 7 on the disk body 2 together with mandrel 4 by ladder hole II 8, be provided with three breach 9 along what the circumference of adpting flange 7 and every group of ladder hole II 8 alternated, the shape of breach 9 and claw 3 are complementary.

Be provided with the mandrel passage at mandrel 4, the mandrel passage by along the passage I 10 of the axis setting of mandrel 4, be arranged on and communicate in the disk 6 and with passage I 10 and perpendicular three passage II 11 and be opened in three apertures 12 that communicate with three passage II 11 respectively on the front end face of disk 6 and form.
