The limiting plate 16 is arranged to limit the turning part of the V-shaped rod head 18 mounted on the circular table 4, so as to prevent the V-shaped rod head 18 from moving axially along the annular barrel 3.

[0026] Working principle:

[0027] When the automobile V-shaped rod head four-axis machining special clamping device is used, one end of the V-shaped rod head 18 is inserted through the through hole 401 on the circular table 4, the annular barrel 3 and the limiting sleeve 5, and the other end is placed in the limiting through slot 402; the abutting screw rod 6 is rotated to abut on the V-shaped rod head 18, so as to preliminarily fix the V-shaped rod head 18; the rotating block 17 is rotated to rotate the rotating shaft 15 and drive the limiting plate 16 to rotate, so that the limiting plate 16 abuts on the turning part of the V-shaped rod head 18, thereby preventing the V-shaped rod head 18 from moving axially along the annular barrel 3.

[0028] When different parts of the V-shaped rod head 18 need to be machined, the abutting screw rod 6 is loosened, the slide rod 8 is pulled, the arc-shaped rack 9 is moved away from the annular rack 31, the annular barrel 3 is rotated, and the annular barrel 3 drives the V-shaped rod head 18 to rotate. During the rotation process, the rotation angle is accurately controlled by observing the angle scale line 11 on the rotating seat 2 and the identification line on the annular barrel 3. After the rotation angle is appropriate, the slide rod 8 is loosened, the arc-shaped rack 9 is engaged with the annular rack 31 outside the annular barrel 3 under the action of the spring 10, the annular barrel 3 is locked at the position, and the abutting screw rod 6 is locked.

[0029] The device avoids frequent operations of taking out and re-clamping the V-shaped rod head 18 in the machining process through the rotatable annular barrel 3 and the positioning assembly, greatly shortens the machining time, and improves the production efficiency.
