Обрабатываемые детали 15, напри- мер, с криволинейной поверхностью В |и прямолинейной С устанавливаются в гнезда приспособления и перемеща- 10 ются вместе с лентой 12 слева направо, При соприкосновении обрабатываемой поверхности В детали с периферией круга 6 соприкасаются и ролики 16 с криволинейной поверхностью Д 15 копиров 17. Поверхности Д, Е, F копиров соответствуют поверхностям В и С обрабатываемой детали, при этом радиус кривизны поверхностей Д и Е копира выбирается в зависимости от диа-__п<метра круга 6 и кривизны поверхности обрабатываемой детали. При дальнейшем движении ленты 12 ролики 16 контактируют с прямолинейным участком Е копира - обрабатывается прямолинейная поверхность С детали.The workpieces 15, for example, with a curved surface B | and rectilinear C, are installed in the fixture sockets and move 10 together with the tape 12 from left to right. When the workpiece B touches the part with the periphery of circle 6, the rollers 16 are in contact with the curved surface D 15 copiers 17. The surfaces D, E, F of the copiers correspond to the surfaces B and C of the workpiece, while the radius of curvature of the surfaces D and E of the copier is selected depending on the diameter _ _{n <} meter of circle 6 and the curvature of the surface of the workpiece the details. With further movement of the tape 12, the rollers 16 are in contact with the rectilinear portion E of the copier - the rectilinear surface C of the part is processed.

С целью увеличения усилия нажима круга 6 на поверхность обрабатываемой детали 15 копир 17 снабжен также нижней опорной поверхностью F, которая соответствует профилю обрабатываемых поверхностей детали 15 и обеспечивает обработку заданной поверхности детали с постоянным нажимом круга 6. Когда усилие нажима круга на деталь 15 меньше усилий, возникаю-35 щих от пружинения ленты 12, рабочей поверхностью копира 17 являются верхние поверхности Д и Е, когда же эти усилия больше, то рабочей поверхностью копира 17 является нижняя поверхность F.In order to increase the pressure force of the circle 6 on the surface of the workpiece 15, the copier 17 is also provided with a lower abutment surface F, which corresponds to the profile of the surfaces of the workpiece 15 and provides processing of the given surface of the part with constant pressure of the circle 6. When the pressure force of the circle on the part 15 is less than arising from the spring of the tape 12, the working surface of the copier 17 is the upper surface D and E, when these forces are greater, the working surface of the copier 17 is the lower surface F.

При окончании обработки ролики 16, контактируя с наклонной поверхностью Q, выходят Из зацепления с копиром 17 и лента 12 возвращается в свое первоначальное положение (вверх). Обрабатываемые детали под действием собственного веса выпадают из приспособления 14 в тару.At the end of processing, the rollers 16, in contact with the inclined surface Q, come out of engagement with the copier 17 and the tape 12 returns to its original position (up). The processed parts under the action of their own weight fall from the device 14 into the container.
