在车床上加工多头螺纹时,常用的分头方法有两种,即:利用小拖板刻度进行分头和利用挂轮齿数进行分头。但是,这两种方法由于分头误差较大和加工效率较低,一般只在单件生产时加工精度要求不高的螺纹零件才采用。下面介绍一种利用乱扣盘进行分头的方法,它在生产批量大、精度要求高、螺纹头数多时,很有实用价值。一、乱扣分头法的原理与计算乱扣盘是在车床上加工单头螺纹时,用于防止螺纹乱扣的一种辅助工具。它是利用乱扣盘上的刻线,使能在工件为整数转数时
In the processing of multi-head lathe thread, there are two commonly used methods of division, that is: the use of small carriage scale division and the use of the number of teeth on the gear. However, these two methods due to larger error and lower processing efficiency, generally only in the production of single-piece machining accuracy of the threaded parts is not used. The following describes a method using the buckle disc to separate, it is in the production of large quantities, high precision requirements, the number of threads when a lot of great practical value. First, the principle of random deduction and the principle of sub-deduction chaos buckle disc is the processing of single-head thread in the lathe, used to prevent thread chaos deduction of an auxiliary tool. It is the use of chaos cut disk engraved lines, enabling the workpiece is an integer number of revolutions
