Description
В ОСНОВНОМ авт. св. № 63282 описан станок дл притирки плоских поверхностей, расположенных в полости втулки, цилиндра и т. п.BASIC Auth. St. No. 63282 described machine for grinding flat surfaces located in the cavity of the sleeve, cylinder, etc.
Насто щее предложение вл етс дальнейшим усовершенствованием основного изобретени путем автоматизации изменени длины хода притира.The present proposal is a further improvement of the basic invention by automating the change in the lap length of the lap.
На фиг. 1 схематически изображен вид по оси звездочки предлагаемого механизма дл изменени величины хода притира; на фиг. 2- вид по стрелке Б на фиг. / с частичным разрезом.FIG. Figure 1 shows schematically a view along the axis of the asterisk of the proposed mechanism for changing the stroke of the lap; in fig. 2 is a view along arrow B in FIG. / with partial cut.
На валу 1 помещен эксцентрик 2, имеющий щестерню 3, котора входит в зацепление с шестерней 4, установленной на эксцентрике 5 (последний имеет эксцентрицитет а относительно вала и эксцентрицитет б относительно эксцентрика 2). Эксцентрик 5 свободно надет на эксцентрик 2, который закреплен на приводном валу.An eccentric 2 is placed on the shaft 1, having a pinion 3, which engages with the gear 4 mounted on the eccentric 5 (the latter has an eccentricity a relative to the shaft and an eccentricite b relative to the eccentric 2). The eccentric 5 is freely mounted on the eccentric 2, which is mounted on the drive shaft.
При вращении вала / и эксцентриков 2 и 5 в направлении стрелки Л звездочка 6, закрепленна на оси шестерни 4, дойдет до упора 7 и начнет поворачивать шестерню 4. Шестерн 4 приведет во вращение щестерню 3, а вместе с ней и эксцентрик 2, при вращении которого изменитс эксцентрицитет а эксцентрика 5.When the shaft / and eccentrics 2 and 5 rotate in the direction of the arrow L, an asterisk 6, fixed on the axis of gear 4, will reach stop 7 and will start to turn gear 4. Gear 4 will cause the rotation of the gear 3, and with it the eccentric 2, during rotation eccentricity of eccentric 5 is changed.
На эксцентрик 5 опираетс ролик 8, установленный на рычаге 9, смонтированном на оси 70. Пальцем 11, установленным на верхнем конце рычага 9, движение передаетс ползуну 12. Обратное движение ползун 12 получает от пружины 13.The eccentric 5 is supported by the roller 8 mounted on the lever 9 mounted on the axis 70. With the finger 11 mounted on the upper end of the lever 9, the movement is transmitted to the slider 12. The return movement slider 12 receives from the spring 13.
Предмет изобретени Subject invention
Форма выполнени станка по п. 2 авторского свидетельства № 63282, отличающа с тем, что дл автоматического изменени хода притира эксцентрик, сообщающий через рычаг движение ползуну, не закреплен на приводном валу, а свободно надет на закрепленный на последнем другой эксцентрик и входит в зацепление с шестерней последнего своей шестерней, на валу которой закреплена звездочка , поворачиваема неподвижным упором при каждом обороте первого эксцентрика дл поворота его на некоторый угол вокруг второго эксцентрика.The form of the machine according to claim 2 of copyright certificate No. 63282, characterized in that to automatically change the course of the lap, the eccentric telling the movement of the slide through the lever is not fixed on the drive shaft, but loosely mounted on the other eccentric fixed on the latter and engages with the gear of the latter with its gear, on the shaft of which a star is fixed, turned by a fixed stop at each revolution of the first eccentric to rotate it through a certain angle around the second eccentric.
