Abstract
Description
Technical Field
[0001] This utility model relates to a mechanical structure, and more particularly to a wheel used in an automatic welding machine, specifically a rubber wheel for an automatic welding machine. Background Technology
[0002] In shipbuilding and other construction projects, magnetic adsorption crawling automatic welding machines are commonly used for steel structure welding. These machines typically employ rubber wheels. The rubber wheel consists of a circular aluminum core coated with a rubber adhesive, which is then heated and vulcanized in a mold to form a rubber layer. This gives the machine high friction and shock absorption, allowing it to move and weld in various positions (horizontal, vertical, horizontal, and overhead). However, thick plate welding involves multiple layers and passes, requiring repeated back-and-forth movement, which continuously increases the heat of the workpiece, raising its surface temperature. Some special steels require heating before welding, with surface temperatures reaching 100-200 degrees Celsius. Under these high-temperature conditions, traditional rubber wheels are prone to delamination and damage between the aluminum core and the rubber layer, rendering them inoperable and severely impacting the normal operation of the welding equipment.
[0003] Therefore, improvements are urgently needed to better meet production demands. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a rubber wheel for an automatic welding machine.
[0005] The technical solution of this utility model is:
[0006] A rubber wheel for an automatic welding machine includes a wheel core and a wheel rim. The wheel core includes a body; the body is disc-shaped with a through-hole-shaped mounting hole at its center, and annular protrusions on both sides of its surface; the protrusions are concentric with the body and their radius is smaller than the radius of the body; a plurality of connecting holes penetrating the body are provided between the protrusions and the outer edge of the body; the wheel rim is made of rubber material, vulcanized and molded to cover the outer edge of the body, and penetrates the connecting holes.
[0007] Furthermore, the distance between the outer periphery of the protrusion and the outer edge of the body is 10mm-15mm.
[0008] Furthermore, the outer edge of the body is provided with flanges protruding to both sides; the height of the flanges is less than the height of the ribs; the rim wraps around the flanges.
[0009] Furthermore, the mounting hole is a D-shaped hole.
[0010] Furthermore, the connecting hole is a round hole or an oblong hole.
[0011] Furthermore, the lower edge of the wheel rim abuts against the outer periphery of the convex ridge.
[0012] The beneficial effects of this utility model are:
[0013] This utility model features a reasonable design, simple structure, and convenient production. By incorporating flanges and ridges to form a stepped mounting structure, it increases the vulcanization adhesion area of the wheel rim, thereby improving the wheel's strength. Simultaneously, by setting multiple connecting holes on the wheel core, it ensures a tight connection between the wheel core and the wheel rim, fully meeting the wheel's axial and radial force requirements and effectively preventing the wheel core and rim from separating due to heat, thus creating favorable conditions for smooth welding operations.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] like Figure 1-4 As shown.
[0021] This utility model relates to a rubber wheel for an automatic welding machine, comprising a wheel core and a wheel rim 6.
[0022] The wheel hub includes a body 1. The body 1 is disc-shaped with a through-hole-shaped mounting hole 2 at its center. This mounting hole 2 is D-shaped, sufficient for the installation and driving of a D-shaped wheel axle. Preferably, the outer edge of the body 1 has flanges 4 protruding to both sides. The height of each flange 4 is 2mm-3mm to enhance support. Both the body 1 and the flanges 4 are made of aluminum or other metal materials.
[0023] The two sides of the body 1 are respectively provided with annular protrusions 5. These protrusions 5 are concentric with the body 1, their radius is smaller than that of the body 1, and the distance between their outer periphery and the outer edge of the body is 10mm-15mm. Simultaneously, the height of the protrusion 5 is greater than the height of the flange 4, and the height difference between the two is ≥5mm, in order to form a stepped structure to meet the installation requirements of the wheel rim. The material of the protrusions 5 is the same as that of the body 1, and they are integrally formed with the body 1.
[0024] The rim 6 is made of rubber material and is vulcanized to cover the outer edge of the body 1, and also wraps around the flange 4. Its width is approximately equal to the distance between the outer ends of the ribs 5, providing sufficient friction to facilitate rolling on the workpiece surface. Preferably, the lower edge of the rim 6 abuts against the outer periphery of the ribs 5, allowing the ribs and flanges to effectively support the rim under pressure and prevent deformation.
[0025] Furthermore, the body 1 between the convex rib 5 and the flange 4 is provided with multiple through-hole-shaped connecting holes 3, so that the wheel rim 6 passes through the connecting holes 3, making the wheel rim and the wheel core tightly connected, improving its strength, and meeting the force requirements of the wheel in the axial and radial directions. Preferably, there are six connecting holes 3, evenly distributed around the circumference of the body 1. At the same time, the connecting holes 3 are round holes or oblong holes. If it is a round hole, its diameter is ≥4mm. In this embodiment, it is an oblong hole, with an arc length of about 10mm and a width of about 6mm, ensuring the connection strength through the rubber material. Thus, when the wheel rim delaminates from the wheel core due to heat, the wheel rim can still ensure a stable connection with the wheel core through the connecting hole structure. Therefore, the problem of the wheel being affected by heat is effectively solved, creating favorable conditions for the smooth progress of welding construction.
[0026] The parts not covered in this utility model are the same as or can be implemented using existing technologies.
