Известно копировальное устройство, ^эсодержащее корпус с закрепленным на нем копиром, плиту, шарнирно соединенную с корпуссял, и установленный на ней шпиндель, в котором радиально размещено не менее двух пальцев, имеющих возможность взаимодействия с рабочими поверхностями копира £1 ].The invention relates to the field of metal cutting and can be used for abrasive processing of curved surfaces. . Known copying device, comprising a housing with ^e cam mounted thereon, a plate pivotally coupled to korpussyal and the spindle mounted thereon, wherein the radially taken by at least two fingers having the ability to interact with the working surfaces of the copier £ 1].

Недостатком известного устройства является'то, что оно позволяет обра- батывать только симметричные поверх- 15. ности, если угол обработки превышает угол рабочего профиля копира.A disadvantage of the known device is that it allows only symmetrical surfaces to be machined if the processing angle exceeds the angle of the working profile of the copier.

Целью изобретения является расширение технологических возможностей путем обеспечения возможности обработ- 20 ки изделий как с симметричными, так и с несимметричными поверхностями.The aim of the invention is to expand technological capabilities by providing the possibility of processing products with both symmetrical and asymmetric surfaces.

Для достижения поставленной цели в копировальном устройстве, содержа- 25 щем корпус с закрепленным на нем копиром, плиту, шарнирно соединенную с корпусом, и установленный на ней шпиндель, в котором радиально размещено не менее двух пальцев,имеющих возможность взаимодействия с рабочими поверхностями копира, согласно \ изобретению рабочие поверхности копира состоят не менее чем из двух ступеней, при этом по крайней мере один из пальцев смещен вдоль оси шпинделя на величину, равную или кратную шагу ступеней.To achieve this goal, a copying device containing 25 a housing with a copier mounted on it, a plate pivotally connected to the housing, and a spindle mounted on it, in which at least two fingers are radially placed that can interact with the working surfaces of the copier, according to According to the invention, the working surfaces of the copier consist of at least two steps, with at least one of the fingers offset along the spindle axis by an amount equal to or a multiple of the step of the steps.

На фиг. 1 изображено устройство, дбщий вид ; на фиг.. 2 - то же, вид сбоку ; на Фиг. 3 - то же, схема.In FIG. 1 shows a device in general view; on Fig .. 2 is the same side view; in FIG. 3 - the same scheme.

Копировальное устройство состоит из корпуса 1, подвижной плиты 2, соединенной с корпусом осью 3. Корпус -установлен на поворотный кронштейн 4, который поставляется вместе с заточкам станком, например, модель ЗА64М. На корпусе закреплен ступенчатый копир 5 с криволинейными поверхностями .The copying device consists of a housing 1, a movable plate 2 connected to the housing by an axis 3. The housing is mounted on a swivel bracket 4, which is supplied with the sharpening machine, for example, model ZA64M. A step copier 5 with curved surfaces is fixed on the body.

На плите 2 смонтирован корпус шпинделя с приспособлением для крепления обрабатываемой детали 6. В опинделе радиально установлены выдвижные пальцы 7. Устройство вместе с кронштейном устанавливают с возможностью поворота на стеле станка. Пальцы 7 смещены один относительно другого вдоль оси шпинделя на величину, равную или кратную шагу ступеней копира. Одни пальцы взаимодействуют с одной ступенью копира, а другие с другой. При вращении шпинделя 7 последовательно взаимодействуют с поверхностями копира, при этом издепие поворачивается в шпинделе и качается вокруг оси 3. В результате этих движений инструмент обрабатывает криволинейную поверхность изделия.A spindle housing with a fixture for mounting the workpiece 6 is mounted on the plate 2. Retractable fingers 7 are radially mounted in the spindle. The device, together with the bracket, is mounted for rotation on the machine stele. The fingers 7 are offset relative to each other along the axis of the spindle by an amount equal to or a multiple of the step of the steps of the copier. Some fingers interact with one step of the copier, and others with another. When the spindle 7 is rotated, they sequentially interact with the surfaces of the copier, while the blank is rotated in the spindle and swings around axis 3. As a result of these movements, the tool processes the curved surface of the product.

Использование данного устройства ,θ позволяет на заточных или шлифовальных станках производить обработку эксцентричных криволинейных поверхностей без существенных затрат, а имея комплект пальцев различной длины, можно обрабатывать идентичные криволинейные поверхности на требуемом удалении от оси вращения шпинделя.Using this device, θ allows grinding or eccentric grinding machines to process eccentric curved surfaces without significant costs, and having a set of fingers of different lengths, you can process identical curved surfaces at the required distance from the axis of rotation of the spindle.

Claims

The invention relates to the field of metal cutting and can be used for abrasive machining of curved surfaces. A copier is known which comprises a housing with a copier fixed on it, a plate pivotally connected to the housing, and a spindle mounted on it in which at least two fingers are radially positioned, and the interaction with the working surfaces of the copier Cl} is a disadvantage. It is clear that it allows only symmetric surfaces to be processed if the processing angle exceeds the angle of the working copier. The aim of the invention is to expand the technological capabilities by providing the possibility of working and products with both single-metric and asymmetrical surfaces. To achieve this goal, a copier with a casing with a copier attached to it, a plate pivotally connected to the casing, and a spindle mounted on it, in which at least two fingers are radially positioned to interact with the working surfaces of the copier, according to the invention, the working surfaces of the copier are; at least one of two steps, with at least one of the fingers being offset along the axis of the spindle by an amount equal to or a multiple of the step of the steps. FIG. 1 shows the device, a general view; in fig. 2 - the same, side view; in FIG. 3 - the same scheme. The copier consists of body 1, a plate 2, connected to the body by axis 3. The body is mounted on a swivel bracket 4, which is supplied with a sharpening machine, for example, model ZA64M. On the case there is a stepped copier 5 with curved surfaces w. On the plate 2, the spindle case is mounted with the fixture for fastening the workpiece 6. The fingers are placed on the ip-index and the fingers 7. The device, together with the bracket, is installed with the possibility of rotation, on the table of the machine. Paldy 7 offset one relative to the axis of the spindle by. equal or multiple step copier steps. One fingers interact with one degree of the copier, and others with another. By rotating the spindle. 7 sequentially interact with the surfaces of the copier, with this, the batch rotates in the spindle and swings around the axis 3. As a result of these movements, the tool processes the curved surface of the product. Using this device allows machining or grinding machines to process eccentric curved surfaces without significant costs, having a set of fingers of various lengths, you can handle identical curved surfaces at a desired distance from the axis of rotation of the spindle. Invention copying machine with a fixed on it there is a copier, a plate, pivotally connected to the body, and mounted on a spindle, in which at least two fingers are radially spaced that have the ability to interact with (working surfaces of the copier, about tl | and 4 and so that, in order to expand technological capabilities by providing the possibility of processing products with both symmetric and asymmetric surfaces The working surfaces of the copier consist of at least two steps, with at least one of the fingers offset along the axis of the spindle by an amount equal to or a multiple of the step of the steps.
