Abstract

Изобретение относитс  к машиностроению и может быть использовано при нарезании внутренних многозаходных резьб. Цель изобретени  - удешевление способа за счет снижени  затрат на изготовление инструмента. Метчику 1 и заготовке 2 сообщают относительное винтовое движение. После нарезани  первого захода вращение останавливают, развертывают метчик на угол, равный 360°/N, где N - число заходов обрабатываемой заготовки. Метчик 1 имеет число заходов в целое число раз меньшее числа заходов нарезаемой резьбы, а шаг резьбы в то же число раз больше шага нарезаемой резьбы. 2 ил.The invention relates to mechanical engineering and can be used when cutting internal multiple threads. The purpose of the invention is to reduce the cost of the method by reducing the cost of manufacturing the tool. Tap 1 and the workpiece 2 reported relative screw movement. After cutting the first run, the rotation is stopped, the tap is rotated through an angle of 360 ° / N, where N is the number of passes of the workpiece. The tap 1 has the number of visits in an integer number of times less than the number of visits of the thread being cut, and the thread lead is the same number of times as long as the thread cut. 2 Il.

Формула изобретенияClaim Способ нарезания внутренней многозаходной резьбы за несколько проходов , каждый из которых производят метчиком при относительном винтовом движении, отличающийся тем, что, с целью снижения затрат на осуществление способа за счет уменьшения количества метчиков, используют метчик, число заходов которого в целое число раз мень’ше числа заходов нарезаемой резьбы, а шаг резьбы - в то же число раз больше шага нарезаемой резьбы, при этом перед каждым последующим проходом витки метчика смещают относительно витков нарезаемой резьбы на величину, равную шагу нарезаемой резьбы.A method of cutting internal multi-threading in several passes, each of which is produced by a tap with relative screw movement, characterized in that, in order to reduce the cost of implementing the method by reducing the number of taps, a tap is used, the number of visits of which is an integer number of times less than the number of runs of the cut thread, and the thread pitch is the same number of times greater than the step of the cut thread, while before each subsequent pass the tap turns are shifted relative to the turns of the cut thread by an amount, p equal to the pitch of the thread being cut.
