Description

-1Изобрегение относитс  к сганкосгроению , а более конкретно к самоценгрируюшим зажимным устройствам и может быт использовано дл  зажима цилиндрических деталей на агрегатных станках и .автЧ)матических лини х. Наиболее близким к изобретению по тезшической сущности и достигаемому эффекту  вл етс , зажимной кулачок с вы полненными рифлеными площадками по С1 1 Недостатком известного кулачка  вл етс  то, что он контакт-ируёт с поверхностью детали только рифлеными поверхност ми губки. На многостаночных автоматических лини х детали в процессе обработки лере сганавливают с одного станка на другой, при этом сохран етс  пространствен - ное положение детали, а контакт детали с зажимными элементами осуществл етс  в одних и тех же точках. Однако при многократном зажиме деталей за одни и те же участки на поверхности детали получаютс  вм тины, ч го отражаетс  на точности цеитрироваюш детали на последующих зажимных приспособлени х , а следовательно и на точности изготовлени . Цель изобретени  - повыщение точности центрировани  деталей при многократном , зажиме.. Указанна  цель достигаетс  гем, что кулачок снабжен гладким дугообразным выступом, наружный радиус которого выбран из услови  равенства радиу- су детали... На фиг. I схематически показано расположение кулачков на зажимном приспособлении; на фиг. 2 - кулачок, обший вид. Кулачок установлен с возможностью поворота на оси I, закрепленной на радиально-подвижном ползуне 2 зажимного приспособлени  (не показано). В средней части кулачок снабжен гладким дугообразным выступом 3, наружный диаметр-1Float refers to scrapping, and more specifically to self-centering clamping devices and can be used to clamp cylindrical parts on aggregate machines and automatical lines. The closest to the invention in terms of practicality and effect achieved is a clamping cam with full grooved pads in C1 1. A disadvantage of the known cam is that it only contacts with the surface of the part with the grooved sponge surfaces. On multi-machine automatic lines, the parts are machined from one machine to another in the course of machining, while maintaining the spatial position of the part, and the contact of the part with the clamping elements is carried out at the same points. However, with multiple clamping of parts for the same areas on the surface of the part, holes are formed, which is reflected in the accuracy of a zeitrizing part on subsequent clamping devices, and consequently on the accuracy of manufacture. The purpose of the invention is to increase the accuracy of part centering with multiple clamping. This goal is achieved that the cam is provided with a smooth arched protrusion, the outer radius of which is chosen from the condition of equality of the part radius ... In FIG. I schematically shows the location of the cams on the jig; in fig. 2 - cam, general view. The cam is pivotably mounted on an I-axis mounted on a radially movable slider 2 of the fixture (not shown). In the middle part, the cam is provided with a smooth arc-shaped protrusion 3, the outer diameter
