Description

Technical Field

[0001] This utility model relates to the field of wheel hub production and processing technology, specifically a wheel rim grinding device. Background Technology

[0002] The wheel rim, also known as the wheel hub, together with the spokes, forms the wheel hub. The rim provides the mounting and securing position for the tire, ensuring a stable connection between the tire and the hub. The rim line is the edge line of the inner rim. Rim line polishing is a crucial step in the production and repair of wheel rims, significantly impacting their quality and performance. This is especially important with the increasing use of tubeless rims, which inevitably exhibit defects such as sharp edges, burrs, and indentations. In practice, appropriate polishing processes and equipment must be selected based on the rim's material, shape, size, and quality requirements. Strict quality control is essential to ensure the rim meets the safety and performance requirements of the vehicle.

[0003] Inconsistent grinding pressure and unstable grinding equipment can lead to over-grinding or inaccurate grinding positions, causing changes in the critical dimensions of the wheel rim. This affects the fit precision between the rim and components such as the tire and hub, resulting in vibration and vehicle drift during driving, seriously impacting driving safety. Furthermore, inconsistent surface roughness of the wheel rim affects the appearance quality and may also affect the effectiveness of subsequent painting or electroplating. Utility Model Content
