我国从五七年开始应用组合夹具,其组装技术主要参考苏联和英国,一直采用可调整式的组装技术。这种组装技术的最大特点是灵活多变、万能性较好,适用于单件和小批生产。但在我国实践中,许多工厂也把组合夹具应用于成批和大批生产,而且要求能用在较大切削用量下保证工作可靠。多年来在推广组合夹具的应用中,由于夹具尺寸是可调的,对于较高精度就不稳定,因此人们不敢放手采用,加上组合夹具对切削用量有一定限制,生产效率低,影响了大量采用。
Our country from the beginning of five or seven years the application of the combination of fixtures, the main reference to the assembly technology Soviet Union and the United Kingdom, has been using adjustable assembly technology. The biggest feature of this assembly technology is flexible and better versatility, suitable for single and small batch production. However, in our practice, many factories also apply the combination fixture to batch and mass production, and they are required to ensure the reliable work under a large cutting load. Over the years in the promotion of the combination of fixture applications, the fixture size is adjustable, for higher accuracy is not stable, so people are afraid to let go, combined with the cutting fixture on the amount of certain restrictions, the production efficiency is low, affecting A lot of use.
