the central driving rod is sleeved with a left movable supporting block body and a right movable supporting block body, a first spring is arranged between the left movable supporting block body and the fixed chassis, a second spring is arranged between the right movable supporting block body and the movable chassis, and the left movable supporting block body and the right movable supporting block body support the elliptic cylinder body.
Furthermore, the left movable supporting block body and the right movable supporting block body are symmetrically distributed.
Furthermore, the joint surface of the left movable support block body and the elliptic cylinder body is an arc surface and is similar to the arc shape of the surface of the elliptic cylinder body.
Furthermore, the joint surface of the right movable support block body and the elliptic cylinder body is an arc surface and is similar to the arc shape of the surface of the elliptic cylinder body.
The utility model has the advantages that the first spring and the second spring are pressed tightly by the cooperation of the dowel bar and the central driving rod, and the elliptic cylinder is supported by the left movable supporting block body and the right movable supporting block body, when the whole body is blocked, the dowel bar is positively rotated to enable the central driving rod and the dowel bar to be relatively separated (incomplete separation, the dowel bar horizontally drives the central driving rod), the prestress of the first spring and the second spring is partially released, the left movable supporting block and the right movable supporting block can slide left and right relative to the central driving rod, the support at the lower part of the elliptic cylinder is loosened, the external equipment horizontally pulls the dowel bar to enable the device to be integrally moved out of the dead-locked position, then reversely rotates to enable the dowel bar to enable the central driving rod and the dowel bar to be relatively close, and prepressing the first spring and the second spring, and fixing the left movable supporting block and the right movable supporting block on the central driving rod.
Drawings
Fig. 1 is a pretension self-adaptive elastic spinning composite die head.
