铝合金汽车轮机加工常用工装夹具分析

Analysis about the Fixture of Aluminum Wheel

机加工工装夹具是保证产品精度的关键因素之一。铝合金车轮是汽车上高速运转的安全部件,为保证车轮的运转精度,需要对铝合金车轮机加工过程的工装夹具进行专门设计。为此,介绍铝合金汽车轮机加工各工序常用的工装夹具,利用六点定位原理分析了数控一序、加工中心序和数控二序工装夹具的定位原理和一般设计方法,对比分析不同工装夹具之间的优缺点和改进措施,并对铝合金汽车车轮机械加工技术进行了展望。

Machining fixture is one of the key factors to ensure product precision. Aluminum alloy wheel is one of the safety components for high speed automobile. In order to ensure the accuracy of the wheel, special design of fixture for machining aluminum alloy wheel is needed. So the fixture used in aluminum wheel machining were introduced, the six-point locating principle in fixture design was applied to analyze the positioning principle and general design methods in numerical control one process, machining center process and numerical control two process, and the advantages and disadvantages of different fixtures were comparatively analyzed and corresponding improvement measures were presented. Finally the aluminum wheel machining technologies were prospected.
