Description

Technical Field

[0001] The utility model relates to a component structure of a tire building machine, in particular to a tire body pulling-out ring rotating disk guide structure of the tire building machine. Background Art

[0002] In the carcass pulling ring structure of the existing giant tire building machine, the extending and contracting cylinder rod drives the rotating disk to rotate and drives the top blocks evenly distributed around the circumference to expand and contract synchronously through the Archimedean spiral groove.

[0003] The rotating disk is installed on the copper sleeve, and the axial positioning of the rotating disk relies on the steps and ribs on the inner and outer sides of the copper sleeve. Since the outer diameter of the rotating disk is too large, in order to reduce friction, the height of the axial positioning steps and ribs is designed to be very low. When the cylinder rod pushes the rotating disk to rotate, it is easy to cause the rotating disk to deform and become stuck, which eventually leads to the expansion and contraction of each top block not being smooth, requiring maintenance personnel to frequently debug and maintain, which is time-consuming and labor-intensive. Utility Model Content

[0004] In order to solve the deficiencies of the prior art, the utility model proposes a tire body pulling-out ring rotating disk guide structure for a tire building machine.

[0005] A tire building machine carcass pulling ring rotating disk guide structure capable of solving the existing technical problems comprises a rotating disk mounted on a copper sleeve, the copper sleeve being mounted on a base, a plurality of cylinders being evenly distributed on the outer circumference of the rotating disk, the cylinder body of each cylinder being hinged to the base via a cylinder seat plate, and the cylinder rod of each cylinder being hinged to the edge of the rotating disk via a rod seat. The difference is that:

[0006] 1. The outer circumference of the base of the rotating disk is evenly distributed with stopper wheel assemblies I. The bearings I of each stopper wheel assembly I are rollingly fitted on the outer surface of the rotating disk. Each bearing I and the step on the inner side of the copper sleeve axially limit the rotating disk.

[0007] 2. Along the rotation direction, a stop wheel assembly II is provided on the rotating disk in front and behind each rod seat. The bearing II of each stop wheel assembly II rolls on the baffle provided on the inner side of the rotating disk to resist the inward deformation of the edge of the rotating disk. The baffle is coaxially mounted on the base.

[0008] Furthermore, the bearing I is mounted on the wheel seat through the shaft I, and the wheel seat is mounted on the base.

[0009] Furthermore, the bearing II is installed in a slot provided on the edge of the rotating disk through the shaft II.

[0010] Furthermore, the baffle and the base are an integrated structure.

[0011] Furthermore, the rotating disk is provided with an Archimedean spiral groove which can drive the top blocks evenly distributed around the circumference to expand and contract synchronously.

[0012] Beneficial effects of the utility model:

[0013] 1. The tire body pulling ring rotating disk guide structure of the tire building machine of the present invention adopts a tire cylinder to drive the rotating disk to rotate. When the cylinder drives the rotating disk to rotate, bearing I is used for axial positioning on one side of the rotating disk to reduce friction, and bearing II is used as a support for the outer edge of the rotating disk to prevent it from deforming inward. The combined effect of bearings I and II ensures smooth rotation of the rotating disk and prevents the disk body from deforming, thereby ensuring the smoothness of the synchronous expansion and contraction of each top block.

[0014] 2. The utility model has a simple and reliable structure, is easy and quick to install, has a low manufacturing cost, and is easy to repair and maintain. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solution of the present utility model will be further described below with reference to the embodiments shown in the accompanying drawings.

[0020] The utility model discloses a tire forming machine carcass pulling ring rotating disk guide structure, comprising a rotating disk 2, the rotating disk 2 is coaxially mounted on a copper sleeve 1, the copper sleeve 1 is fixed on a base 3, dozens of top blocks 10 are evenly distributed coaxially on the inner circumference of the rotating disk 2, and an Archimedean spiral groove 2-1 is opened on the rotating disk 2 corresponding to each top block 10, a plurality of cylinders 4 arranged along the tangential direction are evenly distributed on the outer circumference of the rotating disk 2, the cylinder body of each cylinder 4 is hinged on a cylinder seat plate 5, the cylinder seat plate 5 is fixed on the outer end surface of the base 3, the cylinder rod of each cylinder 4 is hinged on a rod seat 6, and the rod seat 6 is fixed on the circumferential edge of the rotating disk 2, as shown in FIG. Figure 1 shown.

[0021] A plurality of stopper wheel assemblies Ⅰ7 are evenly distributed on the base 3 outside the rotating disk 2, and each stopper wheel assembly Ⅰ7 includes a radial double-row bearing Ⅰ7-1. The bearing Ⅰ7-1 is mounted on the wheel seat 7-3 through the shaft Ⅰ7-2. The wheel seat 7-3 is positioned on the base 3 through the front and rear pins Ⅰ7-4 and then fixed with the front and rear screws Ⅰ7-5. Each bearing Ⅰ7-1 is rollingly fitted on the outer surface of the rotating disk 2. Each bearing Ⅰ7-1 and the step on the inner side of the copper sleeve 1 realize the axial positioning of the rotating disk 2. Figure 1 , as shown in Figure 2(a).

[0022] Along the rotation direction of the rotating disk 2, a stopper assembly II8 is provided on the rotating disk 2 on the front and rear sides of each rod seat 6. The stopper assembly II8 includes a bearing II8-1. The bearing II8-1 is installed in the slot through the shaft II8-2 and the locking nut 8-5. The slot is opened inward at the top of the edge of the rotating disk 2. In order to enhance the strength of the rotating disk 2 at the slot, a connecting block 8-3 is provided at the slot. The connecting block 8-3 is fixed to the outer surface of the rotating disk 2 by front and rear screws II8-4. A baffle 9 is provided on the inner side of the rotating disk 2. The baffle 9 is coaxially mounted on the base 3. Each bearing II8-1 is rollingly fitted on the baffle 9. Figure 1 , as shown in Figure 2(b).

[0023] The operation mode of the utility model is:

[0024] When the cylinder rods of the cylinders 4 extend and contract synchronously to drive the rotating disk 2 to rotate forward and reverse, bearings Ⅰ7-1 are positioned on the outer side of the rotating disk 2 with uniform distribution around the circumference, which can make the rotating disk 2 rotate smoothly and prevent the rotating disk 2 from getting stuck. The smooth rotation of the rotating disk 2 drives the synchronous expansion and contraction of the top blocks 10 to be smoother.

[0025] When the cylinder rods of the cylinders 4 extend and contract synchronously to drive the rotating disk 2 to rotate forward and reverse, and the rotating disk 2 drives the top blocks 10 to expand and contract synchronously, the circumferentially arranged bearings II8-1 move against the baffle 9, effectively preventing the rotating disk 2 from deforming inward due to the force, thereby being more conducive to the flexibility of the synchronous expansion and contraction of the top blocks 10.
