夹具是机械加工中的一种重要工艺装备,它的制造费用在生产成本中占有一定比例,在成批生产和大批量生产的情况下,正确的使用、维护、保养夹具,是延长夹具使用寿命的重要手段。但是就夹具设计本身而言,它对延长夹具的使用寿命也是至关重要的方面。就设计而论,夹具的使用寿命,不仅与夹具零件的强度、刚性有关,而且与夹具某些零件的耐磨性、夹具的结构、尺寸及精度的制订等因素有关。
Fixture is an important process equipment in machining, its manufacturing costs account for a certain proportion of the cost of production, in the case of mass production and mass production, the correct use, maintenance, maintenance of the fixture is to extend the service life of the fixture The important means. But as far as the fixture design itself is concerned, it is also an important aspect of extending the service life of the fixture. In terms of design, the service life of the fixture is not only related to the strength and rigidity of the fixture components, but also to factors such as the wear resistance of certain parts of the fixture, the structure, the size and the precision of the fixture.
