Description

Бабки ведущего винтового барабана бесцентрового шлифовального станка-с двум  соосными опорами дл  приводного вала и дл  шпиндел  ведуш,его барабана, известны.The headstocks of the lead screw drum of a centerless grinding machine — with two coaxial supports for the drive shaft and for the spindle of a lead drum, its drum, are known.

Особенностью предлагаемой подобной бабки  вл етс  применение в качестве шпиндел  барабана неподвижно закрепл емой во второй опоре и переносимой вместе с барабаном с резьбошлифовального станка полой оправки, через полость которой пропушеп поводок дл  врашени  барабана на шарикоподшипниках . Такое выполнение бабки уменьшает биение барабана при его установке после нарезани  винтовой канавки на резьбошлифовальном станке.The peculiarity of the proposed tailstock is the use of a spindle fixedly mounted in the second support and transferred along with the drum from a grinding machine of a hollow mandrel, through which cavity a leash is used to raise the drum on ball bearings. This embodiment of the headstock reduces the drum beating when it is installed after cutting the helical grooves on the thread grinder.

Предлагаема  бабка ноказана на чертеже в продольном разрезе.The proposed grandmother is shown on the drawing in longitudinal section.

Бабка имеет две сооспые опоры } н 2 дл  приводного вала 3 и дл  шпиндел  ведушего барабана 4. В качестве шпиндел  ведушего барабана 4 применена пола  оправка 5. На оправке 5 устанавливаютс  радиально-упорные шарикоподшипники 6, на которых крепитс  ведуш,ийThe headstock has two sososp support} n 2 for the drive shaft 3 and for the spindle of the lead drum 4. As the spindle of the lead drum 4 is used a floor mandrel 5. On the mandrel 5 are installed angular contact ball bearings 6, on which the lead is attached.

барабан 4 бесцентрового шлифовального станка.drum 4 centerless grinding machine.

Оправка 5 с барабаном 4 крепитс  неподвижно на резьбошлифовальном станке, на котором нарезаетс  винтова  ведуш,а  канавка. После нарезани  канавки оправка 5 вместе с барабаном 4 переноситс  в предлагаемую бабку бесцентрового шлифовального станка и здесь закрепл етс  также неподвижно во втулке 7 опоры 2. Таким образом, при перенесении барабана с резьбошлифовального станка на бабку бесцентрового база не мен етс  и биение барабана зависит только от точности шарикоподшипников 6.The mandrel 5 with the drum 4 is fixedly mounted on a thread-grinding machine, on which the lead screw is cut and the groove is cut. After cutting the groove, the mandrel 5 together with the drum 4 is transferred to the proposed head of a centerless grinding machine and is fixed also here in the sleeve 7 of support 2. Thus, when transferring the drum from the grinding machine to the centerless head, the base does not change and the drum beat depends only on precision ball bearings 6.

.Врашение барабану 4 передаетс  поводком 8, который ввинчиваетс  в приводной вал 3 посредством планки 9.The rotation to the drum 4 is transmitted by the driver 8, which is screwed into the drive shaft 3 by means of the strip 9.
