[0003] During the process of assembling the triangular rubber core composite onto the bead, the situation of "over - sleeving" is likely to occur. The so - called "sleeving" is to inflate and expand the rubber core composite with a "drum capsule for application" and then turn it over and attach it to the bead. This process is not easy to control the position of the triangular rubber core composite after turning over, easily producing unqualified products, requiring rework and repair, and reducing the tire production efficiency. Summary of the Utility Model

A bead is sleeved on the positioning part, and a rubber core composite is installed between the bead and the positioning part. The side of the rubber core composite away from the positioning part is turned over and attached to the bead after being extruded by a capsule.

[0007] Further, the positioning part includes a positioning baffle. The edge of the rubber core composite after turning over abuts against the positioning baffle to achieve limit.

[0008] Further, the positioning baffle is installed on a base. The positioning baffle is annular, and the width of the positioning baffle matches the size of the rubber core composite.

[0009] Further, the positioning baffle includes several sub - baffles arranged at intervals. The several sub - baffles are distributed in a circular array on the base.

[0010] Further, the positioning part further includes a bead claw. The bead claw is arc - shaped, perpendicular to the sub - baffle and fixedly connected to the sub - baffle. The bead is sleeved on the periphery of the bead claw.

[0011] Further, the positioning baffle is slidably arranged relative to the base, and the positioning baffle slides on the base to adapt to beads and rubber core composites of different sizes.

[0012] Furthermore, a sliding rod is provided on a side of the positioning baffle away from the tire bead, and the sliding rod is slidably connected to a sliding groove provided on the base.

[0013] Furthermore, a plurality of the sliding grooves are provided, and the extension directions of the plurality of the sliding grooves intersect at the center of the tire bead.

[0014] Furthermore, a limiting block is arranged on one side of the sliding rod away from the positioning baffle, a connecting rod is hinged on the limiting block, and a driving component is hinged on the other end of the connecting rod.

[0026] By providing a positioning portion to support and position the bead 1 and the rubber core composite 2, one side of the rubber core composite 2 is clamped by the bead 1 and the positioning portion. Cooperating with the inflation and expansion of the bladder of the application drum, the rubber core composite 2 is expanded and turned over and sleeved on the bead 1. At the same time, the positioning portion blocks and limits the edge of the turned-over rubber core composite 2, so as to not only control the position of the rubber core composite 2 on the bead 1 after turning over, but also cooperate with the expansion of the bladder of the application drum to make the rubber core composite 2 fit more tightly with the bead 1, improving the product quality and production efficiency.

[0027] In the gripper for fixing a bead and assisting in assembling a rubber core of this embodiment, the positioning portion includes a positioning baffle 3, and the edge of the rubber core composite 2 after being turned over abuts against the positioning baffle 3 to achieve limiting.

[0028] The positioning baffle 3 is provided to block and position the rubber core composite 2 that is turned over and sleeved around the bead 1 by the inflation and extrusion of the airbag, providing a reaction force to make the rubber core composite 2 fit more tightly with the bead 1, and avoiding the problem that the rubber core composite 2 is turned over too long due to excessive inflation of the airbag, which affects the product quality.
