Description

Известны устройства дл  бесцентрово-пр моточного точени  цилиндрических деталей, содержащие роликовый подающий механизм и суппорт с вращающимс  резцом. Однако такие устройства недостаточно универсальны.Devices for centerless-turning turning of cylindrical parts are known, comprising a roller feed mechanism and a support with a rotating cutter. However, such devices are not universal enough.

В описываемом устройстве дл  обработки деталей любой длины применены две группы роликов, установленных по обеим сторонам суппорта на незначительном рассто нии. Кажда  группа содерл :ит по три ролика, расположенные под углом 120° по окружности.In the described device for machining parts of any length, two groups of rollers are used, mounted on both sides of the caliper at an insignificant distance. Each group contains: three rollers each, located at an angle of 120 ° around the circumference.

На фиг. 1 изображена схема устройства; на фиг. 2 - ролик.FIG. 1 shows a diagram of the device; in fig. 2 - video.

Устройство дл  бесцентрово-пр моточного точени  цилиндрических деталей состоит из основани  /, роликового подающего механизма 2, суппорта 5 с вращающимс  резцом 4 и приводного электродвигател  5.The device for centreless turning of cylindrical parts consists of a base /, a roller feed mechanism 2, a support 5 with a rotating cutter 4 and a driving motor 5.

Цилиндрическа  деталь 6, подлежаща  точению, например вал, подаетс  к приемным роликам 7 механизма 2, сгруппированным по обе стороны суппорта 3, объединенным попарно в каждой группе и расположенным под углом 120° по окружности. Один из роликов 7 в паре служит дл  сообщени  детали 6 продольного перемещени , другой - дл  ее поддержки. Дл  компенсации отклонений диаметральных размеров детали 6 от номинала бокова  поверхность роликов 7 выполнена в виде чередующихс  кольцевых выступов 8 и впадин 9. Кольцевые выступы 8 слегка врезаютс  в деталь 6, устран   вли ние размерных погрещностей и одновременно надежно удержива  деталь 6 от проворачивани  под действием усилий резани .A cylindrical part 6 to be turned, for example a shaft, is fed to the receiving rollers 7 of the mechanism 2, grouped on both sides of the support 3, combined in pairs in each group and arranged at an angle of 120 ° around the circumference. One of the rollers 7 in the pair serves to communicate the detail 6 of the longitudinal movement, the other to support it. To compensate for deviations of the diametrical dimensions of the part 6 from the nominal, the lateral surface of the rollers 7 is made in the form of alternating annular protrusions 8 and cavities 9. The annular protrusions 8 slightly cut into part 6, eliminating the effect of dimensional faults and at the same time reliably holding the part 6 from turning under the influence of cutting forces .

Описываемое устройство позвол ет упростить технологический процесс продольного точени  цилиндрических деталей, снизить стоимость их обработки, увеличить производительность токарного оборудовани  и повысить точность готовой продукции при одновременном улучщении качества ее обработки.The described device allows us to simplify the process of longitudinal turning of cylindrical parts, reduce the cost of their processing, increase the productivity of turning equipment and improve the accuracy of the finished product while improving the quality of its processing.
