本文主要论述了普通在双柱立车上车削柱帽和柱窝底平面的不科学方式,并阐述了新式一次装夹六件柱帽或柱窝的夹具设计原理、制做及应用方法和相关注意事项,且该夹具能通过借助不同的垫块实现同步加工不同类型的柱帽或柱窝。两台立车在一起安装运转时,使用该工装夹具可实现人机同工的科学运作模式。 This article mainly discusses the unscientific method of turning the column cap and the bottom of the column bottom on the double-column vertical lathe, and expounds the design principle, manufacturing method, application method and related of the fixture of the new six- Note, and the fixture can be synchronized through the use of different pads to achieve different types of column cap or nest. Two sets of cars together with the installation and operation, the use of the fixture can be achieved with the human-machine scientific mode of operation.
