通用可调整夹具是一种应用于一组工件加工的新型夹具。该类夹具以成本低、投产快、适用范围广等特点,显示了它的强大生命力。 通用可调整夹具依据工件之相似原则实现工件成组,以此指导通用可调整夹具的结构设计。 这种夹具由通用部分和可调部分组成。对业已定型的可调整夹具,其基础件部分是不变的,而其可调部分,则是针对成组工件中每一个工件的具体形状专门设计。 根据上述原则,结合新产品试制和多品种、中小批量生产的特点,在主要机械加工车间,选择了三组工件进行通用可调整夹具的研制。现分述如下:
Universal Adjustable Fixture is a new type of fixture used for machining a set of workpieces. Such fixtures with low cost, fast operation, wide range of applications and other characteristics, shows its strong vitality. Universal adjustable fixture based on the principle of similar parts of the workpiece into a group, in order to guide the universal adjustable fixture structural design. This fixture consists of a universal part and an adjustable part. For the stereotyped adjustable fixture, the basic part is unchanged, and the adjustable part is designed for the specific shape of each of the group of workpieces. According to the above principle, combined with the new product trial and multi-species, small and medium batch production characteristics, in the main mechanical processing workshop, selected three groups of parts for universal adjustable fixture development. Now as follows:
