Wheel positioner for tire building machine

Abstract

The invention relates to a steel ring positioner for a tire building machine. The positioner comprises a positioning block, a connecting seat, a guide rail, a guide rail guiding element and a guide rail driving mechanism, wherein the positioning block is arranged on the connecting seat, the connecting seat is mounted on the guide rail, and the guide rail is movably installed in the guide rail guiding element and moves in the guide rail guiding element under the driven by the guide rail driving mechanism. The positioner is characterized in that the guide rail guiding element employs a sliding block, the sliding block is provided with a sliding chute with a shape matching with the shape of the bottom of the guide rail and the bottom of the guide rail is placed in the sliding chute and can slide relative to the sliding chute. According to the invention, the steel ring positioner has a simple and ingenious structure; the guide rail guiding element in the steel ring positioner is changed from a conventional pulley into the sliding block, so steel ring positioning is more accurate, which is favorable for improvement of tire quality; a reconstruction scheme in the invention is easy, and investment of considerable capital and modification of equipment are not needed; a production process for a reconstructed steel ring positioner remains unchanged, maintenance time and maintenance frequency are reduced, and production efficiency is improved.

Description

technical field [0001] The invention relates to a steel ring positioner used on a tire building machine, belonging to the technical field of tire manufacturing. Background technique [0002] Existing wheeled vehicles, especially large freight vehicles, run on the expressway, not only require a higher speed but also require a better load-bearing capacity, wherein the high load-bearing capacity puts forward more challenges to the tire bead structure of the load-carrying vehicle. high demands. [0003] In order to meet these high requirements, high-precision manufacturing equipment is required in the tire bead manufacturing process to ensure the positioning accuracy of the steel ring in the tire bead structure. In the prior art, the steel ring positioner on the tire building machine is a group of four ( figure 1 shown), installed on the ring fixing frame 2 of the positioning bracket 1. Each rim positioner includes a positioning block 3, a connecting seat 4, a guide rail 7, a...

AI Technical Summary

Problems solved by technology

[0004] In order to ensure the positioning accuracy, the sides of the positioning block 3 on the four steel ring positioners are preferably guaranteed to be on a plane ( figure 2 As shown), since the guide rail guide in the existing steel ring positioner is the pulley 9, the gap between the pulley 9 and the guide rail 7 is relatively large, so that the guide rail 7 will shake up and down during the forward and backward movement, and the four positioning blocks 3 cannot be guaranteed. The side of the tire is on the same plane, which causes the positioning of the steel ring to change, which affects the quality of the tire. It needs to be adjusted frequently, and the adjustment must be adjusted with the help of measuring tools. The maintenance time is increased, the maintenance frequency is high, and the production efficiency is low.
