(54) ПОДВОДИМАЯ ВСПОМОГАТЕЛЬНАЯ ОПОРА(54) SUPPORTING AUXILIARY SUPPORT

1one

Изобретение относитс к металлообработке , в частности к станочной оснастке, предназначенной дл использовани в качестве дополнительной опоры, при обработке нежестких деталей на металлорежущих станках .The invention relates to metal working, in particular, to a machine tool intended for use as an additional support when machining non-rigid parts on machine tools.

Известна подводима вспомогательна опора, содержаща корпус с наклонной плоскостью , на которой установлен ползун и механизм перемещени ползуна 1.The known auxiliary support is supplied, comprising a housing with an inclined plane on which the slider and the mechanism for moving the slider 1 are mounted.

Недостатком известной опоры вл етс ограниченный диапазон размеров обрабатываемых деталей.A disadvantage of the known support is the limited range of sizes of workpieces.

Цель изобретени - расщирение технологических возможностей.The purpose of the invention is the expansion of technological capabilities.

Эта цель достигаетс тем, что предложенна опора снабжена стойкой с элементами креплени и механизмом фиксации корпуса относительно стойки, при этом корпус выполнен в виде кронщтейна и установлен на стойке с возможностью поворота и перемещени относительно ее продольной оси и фиксации в любом промежуточном положении .This goal is achieved by the fact that the proposed support is provided with a stand with fastening elements and a mechanism for fixing the case relative to the stand, wherein the case is made in the form of a bracket and is mounted on the stand with the possibility of rotation and movement relative to its longitudinal axis and fixation in any intermediate position.

На фиг. 1 изображена вспомогательна опора, общий вид; на фиг. 2 - разрез А-А на фиг. 1.FIG. 1 shows auxiliary support, general view; in fig. 2 shows section A-A in FIG. one.

Корпус 1 опоры выполнен в виде кронщтейна , установленного на вертикальной стойке 2 с помощью болта 3, щайбы 4 и гайки 5, закрепленной в Т-образном станочном пазу 6. На корпусе выполнена наклонна плоскость 7, на которой установлен ползун 8, подпружинный плоской пружиной 9 и контактирующий с обрабатываемой деталью 10. Механизм фиксации корпуса относительно стойки выполнен в виде эксцентрика 11, размешенного в пазу корпуса и снабженного ру10 ко ткой 12.The body 1 of the support is made in the form of a bracket mounted on a vertical rack 2 with the help of a bolt 3, a clamp 4 and a nut 5 fixed in a T-shaped machine groove 6. On the body there is an inclined plane 7 on which the slider 8 is mounted, spring-loaded flat spring 9 and in contact with the workpiece 10. The mechanism for fixing the body relative to the stand is made in the form of an eccentric 11 placed in the groove of the body and provided with a key 12.

Подводима вспомогательна опора работает следующим образом.Driven auxiliary support works as follows.

Обрабатываема деталь 10 устанавливаетс в центрах делительной и центровых го15 ловок, закрепленных на столе станка. В соседний Т-образный станочный паз устанавливаетс болт 3, на. стержне которого с помощью щайбы 4 и гайки 5 крепитс стойка 2 опоры с размещенным на ней корпусом 1. Опора в сборе поворачиваетс вокруг оси на The workpiece 10 is installed in the centers of the pivoting and centering points fixed on the table of the machine. A bolt 3 is installed in the adjacent T-shaped machine groove, on. the rod of which with the help of a clamp 4 and a nut 5 secures the support of the support 2 with the housing 1 placed on it. The support assembly rotates around an axis by

Claims

20 is the angle required to place the slider 8 under the workpiece. Turning the handle 12 unlocks the case and disengages the threaded connection of the rack, made on its outer surface. and body, made in the form of semi-nuts. The body rises up to the stop of the slide in the workpiece and is fixed in this position by the eccentric 11. When the body 1 is fastened. In the rack 2, the slide 8 is pushed to the left (Fig. 1) so that a small gap is formed between it and the workpiece, which then chooses moving the slider 8 along the inclined plane 7 under the action of the spring 9. The angle of inclination of the plane 7 and the slider 8 is chosen to be less than the friction angle. The rotation of the workpiece is performed in the opposite direction to the force of the spring of the slider, which at the same time draws the force to the left. After the part has been rotated, the slider returns to the working position under the action of the spring. Part processing operations are performed. The spring-loaded slider ensures a constant force on the workpiece. When installing a new workpiece of the same diameter, the spring-loaded wedge is retracted to the left and released after the part is fixed. When installing a part of a different diameter, the force of the wedge on the supported part is adjusted by the position of the body, which expands the technological capabilities of the support. Claims The inlet auxiliary support comprises a housing with an inclined plane on which a slider is installed and a slider movement mechanism, characterized in that in order to expand technological capabilities by increasing the size range of the parts being machined, the support is provided with a stand with fastening elements and a housing fixation mechanism relative to the rack, with the housing made in the form of a bracket and mounted on the rack with the possibility of rotation and movement relative to its longitudinal axis and fixation in bom intermediate position.
